# NAME

|
# transport 5
|
|
# SUMMARY
|
|
# format of Postfix transport table
|
|
# SYNOPSIS
|
|
# \fBpostmap /etc/postfix/transport\fR
|
|
# DESCRIPTION
|
|
# The optional \fBtransport\fR table specifies a mapping from domain
|
|
# hierarchies to message delivery transports and/or relay hosts. The
|
|
# mapping is used by the \fBtrivial-rewrite\fR(8) daemon.
|
|
#
|
|
# Normally, the \fBtransport\fR table is specified as a text file
|
|
# that serves as input to the \fBpostmap\fR(1) command.
|
|
# The result, an indexed file in \fBdbm\fR or \fBdb\fR format, is used
|
|
# for fast searching by the mail system. Execute the command
|
|
# \fBpostmap /etc/postfix/transport\fR in order to rebuild the indexed
|
|
# file after changing the 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 regular-expression
|
|
# map where patterns are given as regular expressions. In that case,
|
|
# the lookups are done in a slightly different way as described below.
|
|
# TABLE FORMAT
|
|
# .ad
|
|
# .fi
|
|
# The format of the transport table is as follows:
|
|
# .IP "blanks and comments"
|
|
# Blank lines are ignored, as are lines beginning with `#'.
|
|
# .IP "leading whitespace"
|
|
# Lines that begin with whitespace continue the previous line.
|
|
# .IP "\fIpattern result\fR"
|
|
# When \fIpattern\fR matches the domain, use the corresponding
|
|
# \fIresult\fR.
|
|
# .PP
|
|
# 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:
|
|
# .IP "\fIdomain transport\fR:\fInexthop\fR"
|
|
# Mail for \fIdomain\fR is delivered through \fItransport\fR to
|
|
# \fInexthop\fR.
|
|
# .IP "\fI.domain transport\fR:\fInexthop\fR"
|
|
# Mail for any subdomain of \fIdomain\fR is delivered through
|
|
# \fItransport\fR to \fInexthop\fR.
|
|
# .PP
|
|
# Note: transport map entries take precedence over domains
|
|
# specified in the \fBmydestination\fR parameter. If you use
|
|
# the optional transport map, it may be safer to specify explicit
|
|
# entries for all domains specified in \fBmydestination\fR,
|
|
# for example:
|
|
#
|
|
# .ti +5
|
|
# \fBhostname.my.domain local:\fR
|
|
# .ti +5
|
|
# \fBlocalhost.my.domain local:\fR
|
|
#
|
|
# The interpretation of the \fInexthop\fR field is transport
|
|
# dependent. In the case of SMTP, specify \fIhost\fR:\fIservice\fR for a
|
|
# non-default server port, and use [\fIhost\fR] or [\fIhost\fR]:\fIport\fR
|
|
# in order to disable MX (mail exchanger) DNS lookups. The [] form
|
|
# can also be used with IP addresses instead of hostnames.
|
|
# EXAMPLES
|
|
# .ad
|
|
# .fi
|
|
# In order to send mail for \fBfoo.org\fR and its subdomains
|
|
# via the \fBuucp\fR transport to the UUCP host named \fBfoo\fR:
|
|
#
|
|
# .ti +5
|
|
# \fBfoo.org uucp:foo\fR
|
|
# .ti +5
|
|
# \fB\&.foo.org uucp:foo\fR
|
|
#
|
|
# When no \fInexthop\fR host name is specified, the destination domain
|
|
# name is used instead. For example, the following directs mail for
|
|
# \fIuser\fR@\fBfoo.org\fR via the \fBslow\fR transport to a mail
|
|
# exchanger for \fBfoo.org\fR. The \fBslow\fR transport could be
|
|
# something that runs at most one delivery process at a time:
|
|
#
|
|
# .ti +5
|
|
# \fBfoo.org slow:\fR
|
|
#
|
|
# When no \fItransport\fR is specified, the default transport is
|
|
# used, as specified via the \fBdefault_transport\fR configuration
|
|
# parameter. The following sends all mail for \fBfoo.org\fR and its
|
|
# subdomains to host \fBgateway.foo.org\fR:
|
|
#
|
|
# .ti +5
|
|
# \fBfoo.org :[gateway.foo.org]\fR
|
|
# .ti +5
|
|
# \fB\&.foo.org :[gateway.foo.org]\fR
|
|
#
|
|
# In the above example, the [] are used to suppress MX lookups.
|
|
# The result would likely point to your local machine.
|
|
#
|
|
# In the case of delivery via SMTP, one may specify
|
|
# \fIhostname\fR:\fIservice\fR instead of just a host:
|
|
#
|
|
# .ti +5
|
|
# \fBfoo.org smtp:bar.org:2025\fR
|
|
#
|
|
# This directs mail for \fIuser\fR@\fBfoo.org\fR to host \fBbar.org\fR
|
|
# port \fB2025\fR. Instead of a numerical port a symbolic name may be
|
|
# used. Specify [] around the hostname in order to disable MX lookups.
|
|
#
|
|
# The error mailer can be used to bounce mail:
|
|
#
|
|
# .ti +5
|
|
# \fB\&.foo.org error:mail for *.foo.org is not deliverable\fR
|
|
#
|
|
# This causes all mail for \fIuser\fR@\fIanything\fB.foo.org\fR
|
|
# to be bounced.
|
|
# REGULAR EXPRESSION TABLES
|
|
# .ad
|
|
# .fi
|
|
# 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 \fBregexp_table\fR(5)
|
|
# or \fBpcre_table\fR(5).
|
|
#
|
|
# Each pattern is a regular expression that is applied to the entire
|
|
# domain being looked up. Thus, \fIsome.domain.hierarchy\fR is not
|
|
# broken up into parent domains.
|
|
#
|
|
# Patterns are applied in the order as specified in the table, until a
|
|
# pattern is found that matches the search string.
|
|
#
|
|
# Results are the same as with normal indexed file lookups, with
|
|
# the additional feature that parenthesized substrings from the
|
|
# pattern can be interpolated as \fB$1\fR, \fB$2\fR and so on.
