+ | Die Hauptkonfigurationsdatei von Postfix ist **/usr/local/etc/postfix/main.cf** | ||
+ | |||
+ | Anbei eine **main.cf** die angepasst wurde um Mails über einen Relay (in diesem Fall 1und1) zu versenden. | ||
+ | |||
+ | Damit Postfix SASL und TSL unterstützt um Mails über den Relay zu versenden muss Postfix mit folgenden Optionen übersetzt worden sein. | ||

+ | # Global Postfix configuration file. This file lists only a subset | ||
+ | # of all parameters. For the syntax, and for a complete parameter | ||
+ | # list, see the postconf(5) manual page (command: "man 5 postconf"). | ||
+ | # | ||
+ | # For common configuration examples, see BASIC_CONFIGURATION_README | ||
+ | # and STANDARD_CONFIGURATION_README. To find these documents, use | ||
+ | # the command "postconf html_directory readme_directory", or go to | ||
+ | # http://www.postfix.org/. | ||
+ | # | ||
+ | # For best results, change no more than 2-3 parameters at a time, | ||
+ | # and test if Postfix still works after every change. | ||
+ | |||
+ | # SOFT BOUNCE | ||
+ | # | ||
+ | # The soft_bounce parameter provides a limited safety net for | ||
+ | # testing. When soft_bounce is enabled, mail will remain queued that | ||
+ | # would otherwise bounce. This parameter disables locally-generated | ||
+ | # bounces, and prevents the SMTP server from rejecting mail permanently | ||
+ | # (by changing 5xx replies into 4xx replies). However, soft_bounce | ||
+ | # is no cure for address rewriting mistakes or mail routing mistakes. | ||
+ | # | ||
+ | #soft_bounce = no | ||
+ | |||
+ | # LOCAL PATHNAME INFORMATION | ||
+ | # | ||
+ | # The queue_directory specifies the location of the Postfix queue. | ||
+ | # This is also the root directory of Postfix daemons that run chrooted. | ||
+ | # See the files in examples/chroot-setup for setting up Postfix chroot | ||
+ | # environments on different UNIX systems. | ||
+ | # | ||
+ | queue_directory = /var/spool/postfix | ||
+ | |||
+ | # The command_directory parameter specifies the location of all | ||
+ | # postXXX commands. | ||
+ | # | ||
+ | command_directory = /usr/local/sbin | ||
+ | |||
+ | # The daemon_directory parameter specifies the location of all Postfix | ||
+ | # daemon programs (i.e. programs listed in the master.cf file). This | ||
+ | # directory must be owned by root. | ||
+ | # | ||
+ | daemon_directory = /usr/local/libexec/postfix | ||
+ | |||
+ | # The data_directory parameter specifies the location of Postfix-writable | ||
+ | # data files (caches, random numbers). This directory must be owned | ||
+ | # by the mail_owner account (see below). | ||
+ | # | ||
+ | data_directory = /var/db/postfix | ||
+ | |||
+ | # QUEUE AND PROCESS OWNERSHIP | ||
+ | # | ||
+ | # The mail_owner parameter specifies the owner of the Postfix queue | ||
+ | # and of most Postfix daemon processes. Specify the name of a user | ||
+ | # account THAT DOES NOT SHARE ITS USER OR GROUP ID WITH OTHER ACCOUNTS | ||
+ | # AND THAT OWNS NO OTHER FILES OR PROCESSES ON THE SYSTEM. In | ||
+ | # particular, don't specify nobody or daemon. PLEASE USE A DEDICATED | ||
+ | # USER. | ||
+ | # | ||
+ | mail_owner = postfix | ||
+ | |||
+ | # The default_privs parameter specifies the default rights used by | ||
+ | # the local delivery agent for delivery to external file or command. | ||
+ | # These rights are used in the absence of a recipient user context. | ||
+ | # DO NOT SPECIFY A PRIVILEGED USER OR THE POSTFIX OWNER. | ||
+ | # | ||
+ | #default_privs = nobody | ||
+ | |||
+ | # INTERNET HOST AND DOMAIN NAMES | ||
+ | # | ||
+ | # The myhostname parameter specifies the internet hostname of this | ||
+ | # mail system. The default is to use the fully-qualified domain name | ||
+ | # from gethostname(). $myhostname is used as a default value for many | ||
+ | # other configuration parameters. | ||
+ | # | ||
+ | #myhostname = host.domain.tld | ||
+ | #myhostname = virtual.domain.tld | ||
+ | |||
+ | # The mydomain parameter specifies the local internet domain name. | ||
+ | # The default is to use $myhostname minus the first component. | ||
+ | # $mydomain is used as a default value for many other configuration | ||
+ | # parameters. | ||
+ | # | ||
+ | #mydomain = domain.tld | ||
+ | |||
+ | # SENDING MAIL | ||
+ | # | ||
+ | # The myorigin parameter specifies the domain that locally-posted | ||
+ | # mail appears to come from. The default is to append $myhostname, | ||
+ | # which is fine for small sites. If you run a domain with multiple | ||
+ | # machines, you should (1) change this to $mydomain and (2) set up | ||
+ | # a domain-wide alias database that aliases each user to | ||
+ | # user@that.users.mailhost. | ||
+ | # | ||
+ | # For the sake of consistency between sender and recipient addresses, | ||
+ | # myorigin also specifies the default domain name that is appended | ||
+ | # to recipient addresses that have no @domain part. | ||
+ | # | ||
+ | #myorigin = $myhostname | ||
+ | #myorigin = $mydomain | ||
+ | |||
+ | # RECEIVING MAIL | ||
+ | |||
+ | # The inet_interfaces parameter specifies the network interface | ||
+ | # addresses that this mail system receives mail on. By default, | ||
+ | # the software claims all active interfaces on the machine. The | ||
+ | # parameter also controls delivery of mail to user@[ip.address]. | ||
+ | # | ||
+ | # See also the proxy_interfaces parameter, for network addresses that | ||
+ | # are forwarded to us via a proxy or network address translator. | ||
+ | # | ||
+ | # Note: you need to stop/start Postfix when this parameter changes. | ||
+ | # | ||
+ | #inet_interfaces = all | ||
+ | #inet_interfaces = $myhostname | ||
+ | #inet_interfaces = $myhostname, localhost | ||
+ | |||
+ | # The proxy_interfaces parameter specifies the network interface | ||
+ | # addresses that this mail system receives mail on by way of a | ||
+ | # proxy or network address translation unit. This setting extends | ||
+ | # the address list specified with the inet_interfaces parameter. | ||
+ | # | ||
+ | # You must specify your proxy/NAT addresses when your system is a | ||
+ | # backup MX host for other domains, otherwise mail delivery loops | ||
+ | # will happen when the primary MX host is down. | ||
+ | # | ||
+ | #proxy_interfaces = | ||
+ | #proxy_interfaces = 1.2.3.4 | ||
+ | |||
+ | # The mydestination parameter specifies the list of domains that this | ||
+ | # machine considers itself the final destination for. | ||
+ | # | ||
+ | # These domains are routed to the delivery agent specified with the | ||
+ | # local_transport parameter setting. By default, that is the UNIX | ||
+ | # compatible delivery agent that lookups all recipients in /etc/passwd | ||
+ | # and /etc/aliases or their equivalent. | ||
+ | # | ||
+ | # The default is $myhostname + localhost.$mydomain. On a mail domain | ||
+ | # gateway, you should also include $mydomain. | ||
+ | # | ||
+ | # Do not specify the names of virtual domains - those domains are | ||
+ | # specified elsewhere (see VIRTUAL_README). | ||
+ | # | ||
+ | # Do not specify the names of domains that this machine is backup MX | ||
+ | # host for. Specify those names via the relay_domains settings for | ||
+ | # the SMTP server, or use permit_mx_backup if you are lazy (see | ||
+ | # STANDARD_CONFIGURATION_README). | ||
+ | # | ||
+ | # The local machine is always the final destination for mail addressed | ||
+ | # to user@[the.net.work.address] of an interface that the mail system | ||
+ | # receives mail on (see the inet_interfaces parameter). | ||
+ | # | ||
+ | # Specify a list of host or domain names, /file/name or type:table | ||
+ | # patterns, separated by commas and/or whitespace. A /file/name | ||
+ | # pattern is replaced by its contents; a type:table is matched when | ||
+ | # a name matches a lookup key (the right-hand side is ignored). | ||
+ | # Continue long lines by starting the next line with whitespace. | ||
+ | # | ||
+ | # See also below, section "REJECTING MAIL FOR UNKNOWN LOCAL USERS". | ||
+ | # | ||
+ | #mydestination = $myhostname, localhost.$mydomain, localhost | ||
+ | #mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain | ||
+ | #mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain, | ||
+ | #\tmail.$mydomain, www.$mydomain, ftp.$mydomain | ||
+ | |||
+ | # REJECTING MAIL FOR UNKNOWN LOCAL USERS | ||
+ | # | ||
+ | # The local_recipient_maps parameter specifies optional lookup tables | ||
+ | # with all names or addresses of users that are local with respect | ||
+ | # to $mydestination, $inet_interfaces or $proxy_interfaces. | ||
+ | # | ||
+ | # If this parameter is defined, then the SMTP server will reject | ||
+ | # mail for unknown local users. This parameter is defined by default. | ||
+ | # | ||
+ | # To turn off local recipient checking in the SMTP server, specify | ||
+ | # local_recipient_maps = (i.e. empty). | ||
+ | # | ||
+ | # The default setting assumes that you use the default Postfix local | ||
+ | # delivery agent for local delivery. You need to update the | ||
+ | # local_recipient_maps setting if: | ||
+ | # | ||
+ | # - You define $mydestination domain recipients in files other than | ||
+ | # /etc/passwd, /etc/aliases, or the $virtual_alias_maps files. | ||
+ | # For example, you define $mydestination domain recipients in | ||
+ | # the $virtual_mailbox_maps files. | ||
+ | # | ||
+ | # - You redefine the local delivery agent in master.cf. | ||
+ | # | ||
+ | # - You redefine the "local_transport" setting in main.cf. | ||
+ | # | ||
+ | # - You use the "luser_relay", "mailbox_transport", or "fallback_transport" | ||
+ | # feature of the Postfix local delivery agent (see local(8)). | ||
+ | # | ||
+ | # Details are described in the LOCAL_RECIPIENT_README file. | ||
+ | # | ||
+ | # Beware: if the Postfix SMTP server runs chrooted, you probably have | ||
+ | # to access the passwd file via the proxymap service, in order to | ||
+ | # overcome chroot restrictions. The alternative, having a copy of | ||
+ | # the system passwd file in the chroot jail is just not practical. | ||
+ | # | ||
+ | # The right-hand side of the lookup tables is conveniently ignored. | ||
+ | # In the left-hand side, specify a bare username, an @domain.tld | ||
+ | # wild-card, or specify a user@domain.tld address. | ||
+ | # | ||
+ | #local_recipient_maps = unix:passwd.byname $alias_maps | ||
+ | #local_recipient_maps = proxy:unix:passwd.byname $alias_maps | ||
+ | #local_recipient_maps = | ||
+ | |||
+ | # The unknown_local_recipient_reject_code specifies the SMTP server | ||
+ | # response code when a recipient domain matches $mydestination or | ||
+ | # ${proxy,inet}_interfaces, while $local_recipient_maps is non-empty | ||
+ | # and the recipient address or address local-part is not found. | ||
+ | # | ||
+ | # The default setting is 550 (reject mail) but it is safer to start | ||
+ | # with 450 (try again later) until you are certain that your | ||
+ | # local_recipient_maps settings are OK. | ||
+ | # | ||
+ | unknown_local_recipient_reject_code = 550 | ||
+ | |||
+ | # TRUST AND RELAY CONTROL | ||
+ | |||
+ | # The mynetworks parameter specifies the list of "trusted" SMTP | ||
+ | # clients that have more privileges than "strangers". | ||
+ | # | ||
+ | # In particular, "trusted" SMTP clients are allowed to relay mail | ||
+ | # through Postfix. See the smtpd_recipient_restrictions parameter | ||
+ | # in postconf(5). | ||
+ | # | ||
+ | # You can specify the list of "trusted" network addresses by hand | ||
+ | # or you can let Postfix do it for you (which is the default). | ||
+ | # | ||
+ | # By default (mynetworks_style = subnet), Postfix "trusts" SMTP | ||
+ | # clients in the same IP subnetworks as the local machine. | ||
+ | # On Linux, this does works correctly only with interfaces specified | ||
+ | # with the "ifconfig" command. | ||
+ | # | ||
+ | # Specify "mynetworks_style = class" when Postfix should "trust" SMTP | ||
+ | # clients in the same IP class A/B/C networks as the local machine. | ||
+ | # Don't do this with a dialup site - it would cause Postfix to "trust" | ||
+ | # your entire provider's network. Instead, specify an explicit | ||
+ | # mynetworks list by hand, as described below. | ||
+ | # | ||
+ | # Specify "mynetworks_style = host" when Postfix should "trust" | ||
+ | # only the local machine. | ||
+ | # | ||
+ | #mynetworks_style = class | ||
+ | #mynetworks_style = subnet | ||
+ | mynetworks_style = host | ||
+ | |||
+ | # Alternatively, you can specify the mynetworks list by hand, in | ||
+ | # which case Postfix ignores the mynetworks_style setting. | ||
+ | # | ||
+ | # Specify an explicit list of network/netmask patterns, where the | ||
+ | # mask specifies the number of bits in the network part of a host | ||
+ | # address. | ||
+ | # | ||
+ | # You can also specify the absolute pathname of a pattern file instead | ||
+ | # of listing the patterns here. Specify type:table for table-based lookups | ||
+ | # (the value on the table right-hand side is not used). | ||
+ | # | ||
+ | #mynetworks = 168.100.189.0/28, 127.0.0.0/8 | ||
+ | #mynetworks = $config_directory/mynetworks | ||
+ | #mynetworks = hash:$config_directory/network_table | ||
+ | |||
+ | # The relay_domains parameter restricts what destinations this system will | ||
+ | # relay mail to. See the smtpd_recipient_restrictions description in | ||
+ | # postconf(5) for detailed information. | ||
+ | # | ||
+ | # By default, Postfix relays mail | ||
+ | # - from "trusted" clients (IP address matches $mynetworks) to any destination, | ||
+ | # - from "untrusted" clients to destinations that match $relay_domains or | ||
+ | # subdomains thereof, except addresses with sender-specified routing. | ||
+ | # The default relay_domains value is $mydestination. | ||
+ | # | ||
+ | # In addition to the above, the Postfix SMTP server by default accepts mail | ||
+ | # that Postfix is final destination for: | ||
+ | # - destinations that match $inet_interfaces or $proxy_interfaces, | ||
+ | # - destinations that match $mydestination | ||
+ | # - destinations that match $virtual_alias_domains, | ||
+ | # - destinations that match $virtual_mailbox_domains. | ||
+ | # These destinations do not need to be listed in $relay_domains. | ||
+ | # | ||
+ | # Specify a list of hosts or domains, /file/name patterns or type:name | ||
+ | # lookup tables, separated by commas and/or whitespace. Continue | ||
+ | # long lines by starting the next line with whitespace. A file name | ||
+ | # is replaced by its contents; a type:name table is matched when a | ||
+ | # (parent) domain appears as lookup key. | ||
+ | # | ||
+ | # NOTE: Postfix will not automatically forward mail for domains that | ||
+ | # list this system as their primary or backup MX host. See the | ||
+ | # permit_mx_backup restriction description in postconf(5). | ||
+ | # | ||
+ | #relay_domains = $mydestination | ||
+ | |||
+ | # INTERNET OR INTRANET | ||
+ | |||
+ | # The relayhost parameter specifies the default host to send mail to | ||
+ | # when no entry is matched in the optional transport(5) table. When | ||
+ | # no relayhost is given, mail is routed directly to the destination. | ||
+ | # | ||
+ | # On an intranet, specify the organizational domain name. If your | ||
+ | # internal DNS uses no MX records, specify the name of the intranet | ||
+ | # gateway host instead. | ||
+ | # | ||
+ | # In the case of SMTP, specify a domain, host, host:port, [host]:port, | ||
+ | # [address] or [address]:port; the form [host] turns off MX lookups. | ||
+ | # | ||
+ | # If you're connected via UUCP, see also the default_transport parameter. | ||

+ | # REJECTING UNKNOWN RELAY USERS | ||
+ | # | ||
+ | # The relay_recipient_maps parameter specifies optional lookup tables | ||
+ | # with all addresses in the domains that match $relay_domains. | ||
+ | # | ||
+ | # If this parameter is defined, then the SMTP server will reject | ||
+ | # mail for unknown relay users. This feature is off by default. | ||
+ | # | ||
+ | # The right-hand side of the lookup tables is conveniently ignored. | ||
+ | # In the left-hand side, specify an @domain.tld wild-card, or specify | ||
+ | # a user@domain.tld address. | ||
+ | # | ||
+ | #relay_recipient_maps = hash:$config_directory/relay_recipients | ||
+ | |||
+ | # INPUT RATE CONTROL | ||
+ | # | ||
+ | # The in_flow_delay configuration parameter implements mail input | ||
+ | # flow control. This feature is turned on by default, although it | ||
+ | # still needs further development (it's disabled on SCO UNIX due | ||
+ | # to an SCO bug). | ||
+ | # | ||
+ | # A Postfix process will pause for $in_flow_delay seconds before | ||
+ | # accepting a new message, when the message arrival rate exceeds the | ||
+ | # message delivery rate. With the default 100 SMTP server process | ||
+ | # limit, this limits the mail inflow to 100 messages a second more | ||
+ | # than the number of messages delivered per second. | ||
+ | # | ||
+ | # Specify 0 to disable the feature. Valid delays are 0..10. | ||
+ | # | ||
+ | #in_flow_delay = 1s | ||

+ | # ADDRESS REWRITING | ||
+ | # | ||
+ | # The ADDRESS_REWRITING_README document gives information about | ||

+ | # username->Firstname.Lastname mapping. | ||
+ | |||
+ | # ADDRESS REDIRECTION (VIRTUAL DOMAIN) | ||
+ | # | ||

+ | # See the discussion in the ADDRESS_REWRITING_README document. | ||
+ | |||
+ | # ALIAS DATABASE | ||
+ | # | ||
+ | # The alias_maps parameter specifies the list of alias databases used | ||
+ | # by the local delivery agent. The default list is system dependent. | ||
+ | # | ||
+ | # On systems with NIS, the default is to search the local alias | ||
+ | # database, then the NIS alias database. See aliases(5) for syntax | ||
+ | # details. | ||
+ | # | ||
+ | # If you change the alias database, run "postalias /etc/aliases" (or | ||
+ | # wherever your system stores the mail alias file), or simply run | ||
+ | # "newaliases" to build the necessary DBM or DB file. | ||
+ | # | ||
+ | # It will take a minute or so before changes become visible. Use | ||
+ | # "postfix reload" to eliminate the delay. | ||
+ | # | ||
+ | #alias_maps = dbm:/etc/aliases | ||
+ | #alias_maps = hash:/etc/aliases | ||
+ | #alias_maps = hash:/etc/aliases, nis:mail.aliases | ||
+ | #alias_maps = netinfo:/aliases | ||
+ | |||
+ | # The alias_database parameter specifies the alias database(s) that | ||
+ | # are built with "newaliases" or "sendmail -bi". This is a separate | ||
+ | # configuration parameter, because alias_maps (see above) may specify | ||
+ | # tables that are not necessarily all under control by Postfix. | ||
+ | # | ||
+ | #alias_database = dbm:/etc/aliases | ||
+ | #alias_database = hash:/etc/aliases | ||
+ | #alias_database = hash:/etc/aliases, hash:/opt/majordomo/aliases | ||
+ | |||
+ | # ADDRESS EXTENSIONS (e.g., user+foo) | ||
+ | # | ||
+ | # The recipient_delimiter parameter specifies the separator between | ||
+ | # user names and address extensions (user+foo). See canonical(5), | ||
+ | # local(8), relocated(5) and virtual(5) for the effects this has on | ||
+ | # aliases, canonical, virtual, relocated and .forward file lookups. | ||
+ | # Basically, the software tries user+foo and .forward+foo before | ||
+ | # trying user and .forward. | ||
+ | # | ||
+ | #recipient_delimiter = + | ||
+ | |||
+ | # DELIVERY TO MAILBOX | ||
+ | # | ||
+ | # The home_mailbox parameter specifies the optional pathname of a | ||
+ | # mailbox file relative to a user's home directory. The default | ||
+ | # mailbox file is /var/spool/mail/user or /var/mail/user. Specify | ||
+ | # "Maildir/" for qmail-style delivery (the / is required). | ||
+ | # | ||
+ | #home_mailbox = Mailbox | ||
+ | #home_mailbox = Maildir/ | ||
+ | |||
+ | # The mail_spool_directory parameter specifies the directory where | ||
+ | # UNIX-style mailboxes are kept. The default setting depends on the | ||
+ | # system type. | ||
+ | # | ||
+ | #mail_spool_directory = /var/mail | ||
+ | #mail_spool_directory = /var/spool/mail | ||
+ | |||
+ | # The mailbox_command parameter specifies the optional external | ||
+ | # command to use instead of mailbox delivery. The command is run as | ||
+ | # the recipient with proper HOME, SHELL and LOGNAME environment settings. | ||
+ | # Exception: delivery for root is done as $default_user. | ||
+ | # | ||
+ | # Other environment variables of interest: USER (recipient username), | ||
+ | # EXTENSION (address extension), DOMAIN (domain part of address), | ||
+ | # and LOCAL (the address localpart). | ||
+ | # | ||
+ | # Unlike other Postfix configuration parameters, the mailbox_command | ||
+ | # parameter is not subjected to $parameter substitutions. This is to | ||
+ | # make it easier to specify shell syntax (see example below). | ||
+ | # | ||
+ | # Avoid shell meta characters because they will force Postfix to run | ||
+ | # an expensive shell process. Procmail alone is expensive enough. | ||
+ | # | ||
+ | # IF YOU USE THIS TO DELIVER MAIL SYSTEM-WIDE, YOU MUST SET UP AN | ||
+ | # ALIAS THAT FORWARDS MAIL FOR ROOT TO A REAL USER. | ||
+ | # | ||
+ | #mailbox_command = /some/where/procmail | ||
+ | #mailbox_command = /some/where/procmail -a "$EXTENSION" | ||
+ | |||
+ | # The mailbox_transport specifies the optional transport in master.cf | ||
+ | # to use after processing aliases and .forward files. This parameter | ||
+ | # has precedence over the mailbox_command, fallback_transport and | ||
+ | # luser_relay parameters. | ||
+ | # | ||
+ | # Specify a string of the form transport:nexthop, where transport is | ||
+ | # the name of a mail delivery transport defined in master.cf. The | ||
+ | # :nexthop part is optional. For more details see the sample transport | ||
+ | # configuration file. | ||
+ | # | ||
+ | # NOTE: if you use this feature for accounts not in the UNIX password | ||
+ | # file, then you must update the "local_recipient_maps" setting in | ||
+ | # the main.cf file, otherwise the SMTP server will reject mail for | ||

+ | # | ||
+ | #mailbox_transport = lmtp:unix:/file/name | ||
+ | #mailbox_transport = cyrus | ||

+ | # The controls listed here are only a very small subset. The file | ||
+ | # SMTPD_ACCESS_README provides an overview. | ||
+ | |||
+ | # The header_checks parameter specifies an optional table with patterns | ||
+ | # that each logical message header is matched against, including | ||
+ | # headers that span multiple physical lines. | ||
+ | # | ||
+ | # By default, these patterns also apply to MIME headers and to the | ||
+ | # headers of attached messages. With older Postfix versions, MIME and | ||
+ | # attached message headers were treated as body text. | ||
+ | # | ||
+ | # For details, see "man header_checks". | ||
+ | # | ||
+ | #header_checks = regexp:$config_directory/header_checks | ||
+ | |||
+ | # FAST ETRN SERVICE | ||
+ | # | ||
+ | # Postfix maintains per-destination logfiles with information about | ||
+ | # deferred mail, so that mail can be flushed quickly with the SMTP | ||
+ | # "ETRN domain.tld" command, or by executing "sendmail -qRdomain.tld". | ||
+ | # See the ETRN_README document for a detailed description. | ||
+ | # | ||
+ | # The fast_flush_domains parameter controls what destinations are | ||
+ | # eligible for this service. By default, they are all domains that | ||
+ | # this server is willing to relay mail to. | ||
+ | # | ||
+ | #fast_flush_domains = $relay_domains | ||
+ | |||
+ | # SHOW SOFTWARE VERSION OR NOT | ||
+ | # | ||
+ | # The smtpd_banner parameter specifies the text that follows the 220 | ||
+ | # code in the SMTP server's greeting banner. Some people like to see | ||
+ | # the mail version advertised. By default, Postfix shows no version. | ||
+ | # | ||
+ | # You MUST specify $myhostname at the start of the text. That is an | ||
+ | # RFC requirement. Postfix itself does not care. | ||
+ | # | ||
+ | #smtpd_banner = $myhostname ESMTP $mail_name | ||
+ | #smtpd_banner = $myhostname ESMTP $mail_name ($mail_version) | ||
+ | |||
+ | # PARALLEL DELIVERY TO THE SAME DESTINATION | ||
+ | # | ||
+ | # How many parallel deliveries to the same user or domain? With local | ||
+ | # delivery, it does not make sense to do massively parallel delivery | ||
+ | # to the same user, because mailbox updates must happen sequentially, | ||
+ | # and expensive pipelines in .forward files can cause disasters when | ||
+ | # too many are run at the same time. With SMTP deliveries, 10 | ||
+ | # simultaneous connections to the same domain could be sufficient to | ||
+ | # raise eyebrows. | ||
+ | # | ||
+ | # Each message delivery transport has its XXX_destination_concurrency_limit | ||
+ | # parameter. The default is $default_destination_concurrency_limit for | ||
+ | # most delivery transports. For the local delivery agent the default is 2. | ||
+ | |||
+ | #local_destination_concurrency_limit = 2 | ||
+ | #default_destination_concurrency_limit = 20 | ||
+ | |||
+ | # DEBUGGING CONTROL | ||
+ | # | ||
+ | # The debug_peer_level parameter specifies the increment in verbose | ||
+ | # logging level when an SMTP client or server host name or address | ||
+ | # matches a pattern in the debug_peer_list parameter. | ||
+ | # | ||
+ | debug_peer_level = 2 | ||
+ | |||
+ | # The debug_peer_list parameter specifies an optional list of domain | ||
+ | # or network patterns, /file/name patterns or type:name tables. When | ||
+ | # an SMTP client or server host name or address matches a pattern, | ||
+ | # increase the verbose logging level by the amount specified in the | ||
+ | # debug_peer_level parameter. | ||
+ | # | ||
+ | #debug_peer_list = 127.0.0.1 | ||
+ | #debug_peer_list = some.domain | ||
+ | |||
+ | # The debugger_command specifies the external command that is executed | ||
+ | # when a Postfix daemon program is run with the -D option. | ||
+ | # | ||
+ | # Use "command .. & sleep 5" so that the debugger can attach before | ||
+ | # the process marches on. If you use an X-based debugger, be sure to | ||
+ | # set up your XAUTHORITY environment variable before starting Postfix. | ||
+ | # | ||
+ | debugger_command = | ||
+ | \t PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin | ||
+ | \t ddd $daemon_directory/$process_name $process_id & sleep 5 | ||
+ | |||
+ | # If you can't use X, use this to capture the call stack when a | ||
+ | # daemon crashes. The result is in a file in the configuration | ||
+ | # directory, and is named after the process name and the process ID. | ||
+ | # | ||
+ | # debugger_command = | ||
+ | #\tPATH=/bin:/usr/bin:/usr/local/bin; export PATH; (echo cont; | ||
+ | #\techo where) | gdb $daemon_directory/$process_name $process_id 2>&1 | ||
+ | #\t>$config_directory/$process_name.$process_id.log & sleep 5 | ||
+ | # | ||
+ | # Another possibility is to run gdb under a detached screen session. | ||
+ | # To attach to the screen sesssion, su root and run "screen -r | ||
+ | # <id_string>" where <id_string> uniquely matches one of the detached | ||
+ | # sessions (from "screen -list"). | ||
+ | # | ||
+ | # debugger_command = | ||
+ | #\tPATH=/bin:/usr/bin:/sbin:/usr/sbin; export PATH; screen | ||
+ | #\t-dmS $process_name gdb $daemon_directory/$process_name | ||
+ | #\t$process_id & sleep 1 | ||
