SOCKETMAP_TABLE(5)	      File Formats Manual	    SOCKETMAP_TABLE(5)

NAME
       socketmap_table - Postfix socketmap table lookup	client

SYNOPSIS
       postmap -q "string" socketmap:inet:host:port:name
       postmap -q "string" socketmap:unix:pathname:name

       postmap -q - socketmap:inet:host:port:name <inputfile
       postmap -q - socketmap:unix:pathname:name <inputfile

DESCRIPTION
       The  Postfix  mail  system  uses	optional tables	for address rewriting.
       mail routing or policy lookup.

       The Postfix socketmap client expects TCP	endpoint  names	 of  the  form
       inet:host:port:name,  or	 UNIX-domain  endponts	of the form unix:path-
       name:name.  In both cases, name specifies the name field	in a socketmap
       client request (see "REQUEST FORMAT" below).

PROTOCOL
       Socketmaps use a	simple protocol: the client sends one request, and the
       server sends one	reply.	Each request and reply are sent	 as  one  net-
       string object.

REQUEST	FORMAT
       The socketmap protocol supports only the	lookup request.

       Postfix	will  not  generate  partial  search keys such as domain names
       without one or more subdomains, network addresses without one  or  more
       least-significant octets, or email addresses without the	localpart, ad-
       dress extension or domain portion. This behavior	 is  also  found  with
       cidr:, pcre:, and regexp: tables.

       name <space> key
	      Search the named socketmap for the specified key.

REPLY FORMAT
       The  Postfix socketmap client requires that replies are not longer than
       100000 characters (not including	the netstring encapsulation).  Replies
       must have the following form:

       OK <space> data
	      The requested data was found.

       NOTFOUND	<space>
	      The requested data was not found.

       TEMP <space> reason

       TIMEOUT <space> reason

       PERM <space> reason
	      The  request  failed.  The  reason, if non-empty,	is descriptive
	      text.

SECURITY
       This map	cannot be used for security-sensitive information,
       because neither the connection nor the server are authenticated.
