TRIVIAL-REWRITE(8)                             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 sev-
              eral configuration parameters (see below).

       resolve
              Resolve an address to a (transport, nexthop, recip-
              ient) triple. The meaning of the results is as fol-
              lows:

              transport
                     The delivery agent to use. This is the first
                     field of an entry in the master.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 distin-
              guishes between local and non-local mail. For finer
              control  over mail routing, use the optional trans-
              port(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
       environment.




                                                                1

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.

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
       default_transport
              The  default  transport to use when no transport is
              explicitly given in the transport(5) table.

       relayhost
              The default host to send mail to when no  entry  is
              matched in the transport(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.
