CLEANUP(8) CLEANUP(8)

NAME

cleanup - canonicalize and enqueue Postfix message

SYNOPSIS

cclleeaannuupp [generic Postfix daemon options]

DESCRIPTION

The cclleeaannuupp daemon processes inbound mail, inserts it into the iinnccoommiinngg mail queue, and informs the queue manager of its arrival. The cclleeaannuupp daemon always performs the following transformations:

+o Insert missing message headers: (RReesseenntt-) FFrroomm::, TToo::, MMeessssaaggee-

IIdd::, and DDaattee::. +o Transform envelope and header addresses to the standard

user@fully-qualified-domain form that is expected by other Post-

fix programs. This task is delegated to the ttrriivviiaall-rreewwrriittee(8)

daemon. +o Eliminate duplicate envelope recipient addresses. The following address transformations are optional: +o Optionally, rewrite all envelope and header addresses according to the mappings specified in the ccaannoonniiccaall(5) lookup tables. +o Optionally, masquerade envelope sender addresses and message header addresses (i.e. strip host or domain information below all domains listed in the mmaassqquueerraaddeeddoommaaiinnss parameter, except for user names listed in mmaassqquueerraaddeeeexxcceeppttiioonnss). By default, address masquerading does not affect envelope recipients. +o Optionally, expand envelope recipients according to information found in the vviirrttuuaall(5) lookup tables.

The cclleeaannuupp daemon performs sanity checks on the content of each mes-

sage. When it finds a problem, by default it returns a diagnostic sta-

tus to the client, and leaves it up to the client to deal with the problem. Alternatively, the client can request the cclleeaannuupp daemon to bounce the message back to the sender in case of trouble. STANDARDS RFC 822 (ARPA Internet Text Messages) RFC 2045 (MIME: Format of Internet Message Bodies) RFC 2046 (MIME: Media Types) DIAGNOSTICS Problems and transactions are logged to ssyyssllooggdd(8).

other logical relationships. CCOONNFFIIGGUURRAATTIIOONN PPAARRAAMMEETTEERRSS

Changes to mmaaiinn..ccff are picked up automatically, as cleanup(8) processes

run for only a limited amount of time. Use the command "ppoossttffiixx rreellooaadd" to speed up a change. The text below provides only a parameter summary. See postconf(5) for more details including examples. CCOOMMPPAATTIIBBIILLIITTYY CCOONNTTRROOLLSS
