+NAME
+       tcp_table - Postfix client/server table lookup protocol
+
+SYNOPSIS
+       postmap -q "string" tcp:host:port
+
+       postmap -q - tcp:host:port <inputfile
+
+DESCRIPTION
+       The  Postfix  mail system uses optional tables for address rewriting or
+       mail routing. These tables are usually in dbm or  db  format.  Alterna-
+       tively, table lookups can be directed to a TCP server.
+
+       To  find  out  what types of lookup tables your Postfix system supports
+       use the "postconf -m" command.
+
+       To test lookup tables, use the "postmap -q" command as described in the
+       SYNOPSIS above.
+
+PROTOCOL DESCRIPTION
+       The TCP map class implements a very simple protocol: the client sends a
+       request, and the server sends one reply. Requests and replies are  sent
+       as  one  line of ASCII text, terminated by the ASCII newline character.
+       Request and reply parameters (see below) are separated by whitespace.
+
+       Send and receive operations must complete in 100 seconds.
+
+REQUEST FORMAT
+       The tcp_table protocol supports only the lookup request.   The  request
+       has the following form:
+
+       get SPACE key NEWLINE
+              Look up data under the specified key.
+
+       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,
+       address extension or domain portion. This behavior is also  found  with
+       cidr:, pcre:, and regexp: tables.
+
+REPLY FORMAT
+       Each  reply specifies a status code and text. Replies must be no longer
+       than 4096 characters including the newline terminator.
+
+       500 SPACE text NEWLINE
+              In case of a lookup request, the requested data does not  exist.
+              The text describes the nature of the problem.
+
+       400 SPACE text NEWLINE
+              This indicates an error condition. The text describes the nature
+              of the problem. The client should retry the request later.
+
+       200 SPACE text NEWLINE
+              The request was successful. In the case of a lookup request, the
+              text contains an encoded version of the requested data.
+
+ENCODING
+       In  request  and  reply  parameters, the character %, each non-printing
+       character, and each whitespace character must be replaced by %XX, where
+       XX is the corresponding ASCII hexadecimal character value. The hexadec-
+       imal codes can be specified in any case (upper, lower, mixed).
+
+       The Postfix client always encodes a request.  The server may  omit  the
+       encoding  as  long  as  the reply is guaranteed to not contain the % or
+       NEWLINE character.
+
+SECURITY
+       Do not use TCP lookup  tables  for  security  critical  purposes.   The
+       client-server connection is not protected and the server is not authen-
+       ticated.
+
+BUGS
+       Only the lookup method is currently implemented.
+
+       The client does not hang up when the connection  is  idle  for  a  long
+       time.
