# TRANSPORT(5) TRANSPORT(5)
|
||||
#
|
||||
# NAME
|
||||
# transport - Postfix transport table format
|
||||
#
|
||||
# SYNOPSIS
|
||||
# postmap /etc/postfix/transport
|
||||
#
|
||||
# postmap -q "string" /etc/postfix/transport
|
||||
#
|
||||
# postmap -q - /etc/postfix/transport <inputfile
|
||||
#
|
||||
# DESCRIPTION
|
||||
# The optional transport(5) table specifies a mapping from
|
||||
# email addresses to message delivery transports and
|
||||
# next-hop destinations. Message delivery transports such
|
||||
# as local or smtp are defined in the master.cf file, and
|
||||
# next-hop destinations are typically hosts or domain names.
|
||||
# The table is searched by the trivial-rewrite(8) daemon.
|
||||
#
|
||||
# This mapping overrides the default transport:nexthop
|
||||
# selection that is built into Postfix:
|
||||
#
|
||||
# local_transport (default: local:$myhostname)
|
||||
# This is the default for final delivery to domains
|
||||
# listed with mydestination, and for [ipaddress] des-
|
||||
# tinations that match $inet_interfaces or
|
||||
# $proxy_interfaces. The default nexthop destination
|
||||
# is the MTA hostname.
|
||||
#
|
||||
# virtual_transport (default: virtual:)
|
||||
# This is the default for final delivery to domains
|
||||
# listed with virtual_mailbox_domains. The default
|
||||
# nexthop destination is the recipient domain.
|
||||
#
|
||||
# relay_transport (default: relay:)
|
||||
# This is the default for remote delivery to domains
|
||||
# listed with relay_domains. In order of decreasing
|
||||
# precedence, the nexthop destination is taken from
|
||||
# relay_transport, sender_dependent_relayhost_maps,
|
||||
# relayhost, or from the recipient domain.
|
||||
#
|
||||
# default_transport (default: smtp:)
|
||||
# This is the default for remote delivery to other
|
||||
# destinations. In order of decreasing precedence,
|
||||
# the nexthop destination is taken from sender_depen-
|
||||
# dent_default_transport_maps, default_transport,
|
||||
# sender_dependent_relayhost_maps, relayhost, or from
|
||||
# the recipient domain.
|
||||
#
|
||||
# Normally, the transport(5) table is specified as a text
|
||||
# file that serves as input to the postmap(1) command. The
|
||||
# result, an indexed file in dbm or db format, is used for
|
||||
# fast searching by the mail system. Execute the command
|
||||
# "postmap /etc/postfix/transport" to rebuild an indexed
|
||||
# file after changing the corresponding transport table.
|
||||
#
|
||||
# When the table is provided via other means such as NIS,
|
||||
# LDAP or SQL, the same lookups are done as for ordinary
|
||||
# indexed files.
|
||||
#
|
||||
# Alternatively, the table can be provided as a regu-
|
||||
# lar-expression map where patterns are given as regular
|
||||
# expressions, or lookups can be directed to a TCP-based
|
||||
# server. In those case, the lookups are done in a slightly
|
||||
# different way as described below under "REGULAR EXPRESSION
|
||||
# TABLES" or "TCP-BASED TABLES".
|
||||
#
|
||||
# CASE FOLDING
|
||||
# The search string is folded to lowercase before database
|
||||
# lookup. As of Postfix 2.3, the search string is not case
|
||||
# folded with database types such as regexp: or pcre: whose
|
||||
# lookup fields can match both upper and lower case.
|
||||
#
|
||||
# TABLE FORMAT
|
||||
# The input format for the postmap(1) command is as follows:
|
||||
#
|
||||
# pattern result
|
||||
# When pattern matches the recipient address or
|
||||
# domain, use the corresponding result.
|
||||
#
|
||||
# blank lines and comments
|
||||
# Empty lines and whitespace-only lines are ignored,
|
||||
# as are lines whose first non-whitespace character
|
||||
# is a `#'.
|
||||
#
|
||||
# multi-line text
|
||||
# A logical line starts with non-whitespace text. A
|
||||
# line that starts with whitespace continues a logi-
|
||||
# cal line.
|
||||
#
|
||||
# The pattern specifies an email address, a domain name, or
|
||||
# a domain name hierarchy, as described in section "TABLE
|
||||
# SEARCH ORDER".
|
||||
#
|
||||
# The result is of the form transport:nexthop and specifies
|
||||
# how or where to deliver mail. This is described in section
|
||||
# "RESULT FORMAT".
|
||||
#
|
||||
# TABLE SEARCH ORDER
|
||||
# With lookups from indexed files such as DB or DBM, or from
|
||||
# networked tables such as NIS, LDAP or SQL, patterns are
|
||||
# tried in the order as listed below:
|
||||
#
|
||||
# user+extension@domain transport:nexthop
|
||||
# Deliver mail for user+extension@domain through
|
||||
# transport to nexthop.
|
||||
#
|
||||
# user@domain transport:nexthop
|
||||
# Deliver mail for user@domain through transport to
|
||||
# nexthop.
|
||||
#
|
||||
# domain transport:nexthop
|
||||
# Deliver mail for domain through transport to nex-
|
||||
# thop.
|
||||
#
|
||||
# .domain transport:nexthop
|
||||
# Deliver mail for any subdomain of domain through
|
||||
# transport to nexthop. This applies only when the
|
||||
# string transport_maps is not listed in the par-
|
||||
# ent_domain_matches_subdomains configuration set-
|
||||
# ting. Otherwise, a domain name matches itself and
|
||||
# its subdomains.
|
||||
#
|
||||
# * transport:nexthop
|
||||
# The special pattern * represents any address (i.e.
|
||||
# it functions as the wild-card pattern, and is
|
||||
# unique to Postfix transport tables).
|
||||
#
|
||||
# Note 1: the null recipient address is looked up as
|
||||
# $empty_address_recipient@$myhostname (default: mailer-dae-
|
||||
# mon@hostname).
|
||||
#
|
||||
# Note 2: user@domain or user+extension@domain lookup is
|
||||
# available in Postfix 2.0 and later.
|
||||
#
|
||||
# RESULT FORMAT
|
||||
# The lookup result is of the form transport:nexthop. The
|
||||
# transport field specifies a mail delivery transport such
|
||||
# as smtp or local. The nexthop field specifies where and
|
||||
# how to deliver mail.
|
||||
#
|
||||
# The transport field specifies the name of a mail delivery
|
||||
# transport (the first name of a mail delivery service entry
|
||||
# in the Postfix master.cf file).
|
||||
#
|
||||
# The nexthop field usually specifies one recipient domain
|
||||
# or hostname. In the case of the Postfix SMTP/LMTP client,
|
||||
# the nexthop field may contain a list of nexthop destina-
|
||||
# tions separated by comma or whitespace (Postfix 3.5 and
|
||||
# later).
|
||||
#
|
||||
# The syntax of a nexthop destination is transport depen-
|
||||
# dent. With SMTP, specify a service on a non-default port
|
||||
# as host:service, and disable MX (mail exchanger) DNS
|
||||
# lookups with [host] or [host]:port. The [] form is
|
||||
# required when you specify an IP address instead of a host-
|
||||
# name.
|
||||
#
|
||||
# A null transport and null nexthop field means "do not
|
||||
# change": use the delivery transport and nexthop informa-
|
||||
# tion that would be used when the entire transport table
|
||||
# did not exist.
|
||||
#
|
||||
# A non-null transport field with a null nexthop field
|
||||
# resets the nexthop information to the recipient domain.
|
||||
#
|
||||
# A null transport field with non-null nexthop field does
|
||||
# not modify the transport information.
|
||||
#
|
||||
# EXAMPLES
|
||||
# In order to deliver internal mail directly, while using a
|
||||
# mail relay for all other mail, specify a null entry for
|
||||
# internal destinations (do not change the delivery trans-
|
||||
# port or the nexthop information) and specify a wildcard
|
||||
# for all other destinations.
|
||||
#
|
||||
# my.domain :
|
||||
# .my.domain :
|
||||
# * smtp:outbound-relay.my.domain
|
||||
#
|
||||
# In order to send mail for example.com and its subdomains
|
||||
# via the uucp transport to the UUCP host named example:
|
||||
#
|
||||
# example.com uucp:example
|
||||
# .example.com uucp:example
|
||||
#
|
||||
# When no nexthop host name is specified, the destination
|
||||
# domain name is used instead. For example, the following
|
||||
# directs mail for user@example.com via the slow transport
|
||||
# to a mail exchanger for example.com. The slow transport
|
||||
# could be configured to run at most one delivery process at
|
||||
# a time:
|
||||
#
|
||||
# example.com slow:
|
||||
#
|
||||
# When no transport is specified, Postfix uses the transport
|
||||
# that matches the address domain class (see DESCRIPTION
|
||||
# above). The following sends all mail for example.com and
|
||||
# its subdomains to host gateway.example.com:
|
||||
#
|
||||
# example.com :[gateway.example.com]
|
||||
# .example.com :[gateway.example.com]
|
||||
#
|
||||
# In the above example, the [] suppress MX lookups. This
|
||||
# prevents mail routing loops when your machine is primary
|
||||
# MX host for example.com.
|
||||
#
|
||||
# In the case of delivery via SMTP or LMTP, one may specify
|
||||
# host:service instead of just a host:
|
||||
#
|
||||
# example.com smtp:bar.example:2025
|
||||
#
|
||||
# This directs mail for user@example.com to host bar.example
|
||||
# port 2025. Instead of a numerical port a symbolic name may
|
||||
# be used. Specify [] around the hostname if MX lookups must
|
||||
# be disabled.
|
||||
#
|
||||
# Deliveries via SMTP or LMTP support multiple destinations
|
||||
# (Postfix >= 3.5):
|
||||
#
|
||||
# example.com smtp:bar.example, foo.example
|
||||
#
|
||||
# This tries to deliver to bar.example before trying to
|
||||
# deliver to foo.example.
|
||||
#
|
||||
# The error mailer can be used to bounce mail:
|
||||
#
|
||||
# .example.com error:mail for *.example.com is not deliverable
|
||||
#
|
||||
# This causes all mail for user@anything.example.com to be
|
||||
# bounced.
|
||||
#
|
||||
# REGULAR EXPRESSION TABLES
|
||||
# This section describes how the table lookups change when
|
||||
# the table is given in the form of regular expressions. For
|
||||
# a description of regular expression lookup table syntax,
|
||||
# see regexp_table(5) or pcre_table(5).
|
||||
#
|
||||
# Each pattern is a regular expression that is applied to
|
||||
# the entire address being looked up. Thus,
|
||||
# some.domain.hierarchy is not looked up via its parent
|
||||
# domains, nor is user+foo@domain looked up as user@domain.
|
||||
#
|
||||
# Patterns are applied in the order as specified in the ta-
|
||||
# ble, until a pattern is found that matches the search
|
||||
# string.
|
||||
#
|
||||
# The trivial-rewrite(8) server disallows regular expression
|
||||
# substitution of $1 etc. in regular expression lookup
|
||||
# tables, because that could open a security hole (Postfix
|
||||
# version 2.3 and later).
|
||||
#
|
||||
# TCP-BASED TABLES
|
||||
# This section describes how the table lookups change when
|
||||
# lookups are directed to a TCP-based server. For a descrip-
|
||||
# tion of the TCP client/server lookup protocol, see tcp_ta-
|
||||
# ble(5). This feature is not available up to and including
|
||||
# Postfix version 2.4.
|
||||
#
|
||||
# Each lookup operation uses the entire recipient address
|
||||
# once. Thus, some.domain.hierarchy is not looked up via
|
||||
# its parent domains, nor is user+foo@domain looked up as
|
||||
# user@domain.
|
||||
#
|
||||
# Results are the same as with indexed file lookups.
|
||||
#
|
||||
# CONFIGURATION PARAMETERS
