+.SH DESCRIPTION
+.ad
+.fi
+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 \fBinet:\fIhost\fB:\fIport\fB:\fIname\fR, or
+UNIX\-domain endpoints of the form \fBunix:\fIpathname\fB:\fIname\fR.
+In both cases, \fIname\fR specifies the name field in a
+socketmap client request (see "REQUEST FORMAT" below).
+.SH "PROTOCOL"
+.na
+.nf
+.ad
+.fi
+Socketmaps use a simple protocol: the client sends one
+request, and the server sends one reply. Each request and
+each reply are sent as one netstring object.
+.SH "REQUEST FORMAT"
+.na
+.nf
+.ad
+.fi
+The socketmap protocol supports only the lookup request.
+The request has the following form:
+
+.IP "\fB\fIname\fB <space> \fIkey\fR"
+Search the named socketmap for the specified key.
+.PP
+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.
+.SH "REPLY FORMAT"
+.na
+.nf
+.ad
+.fi
+The Postfix socketmap client requires that replies are not
+longer than 100000 characters (not including the netstring
+encapsulation). Replies must have the following form:
+.IP "\fBOK <space> \fIdata\fR"
+The requested data was found.
+.IP "\fBNOTFOUND <space>"
+The requested data was not found.
+.IP "\fBTEMP <space> \fIreason\fR"
+.IP "\fBTIMEOUT <space> \fIreason\fR"
+.IP "\fBPERM <space> \fIreason\fR"
+The request failed. The reason, if non\-empty, is descriptive
+text.
+.SH "SECURITY"
+.na
+.nf
+This map cannot be used for security\-sensitive information,
+because neither the connection nor the server are authenticated.
