TRIVIAL-REWRITE(8)		     System Manager's Manual		       TRIVIAL-REWRITE(8)

NAME
       trivial-rewrite - Postfix address rewriting and resolving daemon

SYNOPSIS
       trivial-rewrite [generic Postfix daemon options]

DESCRIPTION
       The trivial-rewrite daemon processes two types of client service requests:

       rewrite
	      Rewrite  an address to standard form. The trivial-rewrite daemon by default appends
	      local domain information to unqualified addresses, swaps bang paths to domain form,
	      and  strips  source  routing  information. This process is under control of several
	      configuration parameters (see below).

       resolve
	      Resolve an address to a (transport, nexthop, recipient) triple. The meaning of  the
	      results is as follows:

	      transport
		     The  delivery  agent to use. This is the first field of an entry in the mas-
		     ter.cf file.

	      nexthop
		     The host to send to. For local delivery this is an empty string.

	      recipient
		     The envelope recipient address that is passed on to nexthop.

	      The trivial-rewrite daemon by default only distinguishes	between  local	and  non-
	      local  mail.  For  finer	control  over mail routing, use the optional transport(5)
	      lookup table.

       This program expects to be run from the master(8) process manager.

STANDARDS
       None. The command does not interact with the outside world.

SECURITY
       The trivial-rewrite daemon is not security sensitive.  By default, this	daemon	does  not
       talk to remote or local users.  It can run at a fixed low privilege in a chrooted environ-
       ment.

DIAGNOSTICS
       Problems and transactions are logged to syslogd(8).

BUGS
CONFIGURATION PARAMETERS
       The following main.cf parameters are especially relevant to this program. See the  Postfix
       main.cf	file  for  syntax  details and for default values. Use the postfix reload command
       after a configuration change.

Miscellaneous
       inet_interfaces
	      The network interfaces that this mail system receives mail on.  This information is
	      used to determine if user@[net.work.addr.ess] is local or remote.

       mydestination
	      List of domains that this machine considers local.

       myorigin
	      The domain that locally-posted mail appears to come from.

       resolve_unquoted_address
	      When  resolving  an  address, do not quote the address localpart as per RFC 822, so
	      that additional @, % or !  characters remain visible. This  is  technically  incor-
	      rect,  but  allows us to stop relay attacks when forwarding mail to a Sendmail pri-
	      mary MX host.

Rewriting
       allow_percent_hack
	      Rewrite user%domain to user@domain.

       append_at_myorigin
	      Rewrite user to user@$myorigin.

       append_dot_mydomain
	      Rewrite user@host to user@host.$mydomain.

       swap_bangpath
	      Rewrite site!user to user@site.

Routing
       local_transport
	      Where to deliver mail for destinations that match  $mydestination  or  $inet_inter-
	      faces.  The default transport is local.

	      Syntax  is  transport:nexthop;  see  transport(5) for details. The :nexthop part is
	      optional.

       default_transport
	      Where to deliver non-local mail when no information  is  explicitly  given  in  the
	      transport(5) table.  The default transport is smtp.

	      Syntax  is  transport:nexthop;  see  transport(5) for details. The :nexthop part is
	      optional.

       parent_domain_matches_subdomains
	      List of Postfix features that use domain.tld patterns to match  sub.domain.tld  (as
	      opposed to requiring .domain.tld patterns).

       relayhost
	      The  default  host to send non-local mail to when no entry is matched in the trans-
	      port(5) table.

	      When no relayhost is specified, mail is routed directly to the  destination's  mail
	      exchanger.

       transport_maps
	      List of tables with domain to (transport, nexthop) mappings.
