+# 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 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
+# LOOKUP".
+#
+# 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
+# The following main.cf parameters are especially relevant.
+# The text below provides only a parameter summary. See
+# postconf(5) for more details including examples.
+#
+# empty_address_recipient (MAILER-DAEMON)
+# The recipient of mail addressed to the null
+# address.
+#
+# parent_domain_matches_subdomains (see 'postconf -d' out-
+# put)
+# A list of Postfix features where the pattern "exam-
+# ple.com" also matches subdomains of example.com,
+# instead of requiring an explicit ".example.com"
+# pattern.
+#
+# transport_maps (empty)
+# Optional lookup tables with mappings from recipient
+# address to (message delivery transport, next-hop
+# destination).
