The table name is +\fBinet\fR:\fIhost\fR:\fIport\fR:\fIname\fR for a TCP/IP +server, or \fBunix\fR:\fIpathname\fR:\fIname\fR for a +UNIX\-domain server. This is described in \fBsocketmap_table\fR(5). + +This feature is available with Postfix 2.10 and later. +.IP "\fBsqlite\fR (read\-only)" +SQLite database. This is described in \fBsqlite_table\fR(5). + +This feature is available with Postfix 2.8 and later. +.IP "\fBstatic\fR (read\-only)" +A table that always returns its name as lookup result. For +example, \fBstatic:foobar\fR always returns the string +\fBfoobar\fR as lookup result. Specify "\fBstatic:{ \fItext +with whitespace\fB }\fR" when the result contains whitespace; +this form ignores whitespace after the opening "\fB{\fR" +and before the closing +"\fB}\fR". See also the \fIinline:\fR map. + +The form "\fBstatic:{\fItext\fB}\fR is available with Postfix +3.0 and later. +.IP "\fBtcp\fR (read\-only)" +TCP/IP client. The protocol is described in \fBtcp_table\fR(5). +.IP "\fBtexthash\fR (read\-only)" +Produces similar results as hash: files, except that you +don't need to run the \fBpostmap\fR(1) command before you +can use the file, and that it does not detect changes after +the file is read. + +This feature is available with Postfix 2.8 and later. +.IP "\fBunionmap\fR (read\-only)" +A table that sends each query to multiple lookup tables and +that concatenates all found results, separated by comma. +The table name syntax is the same as for \fBpipemap\fR. + +This feature is available with Postfix 3.0 and later. +.IP "\fBunix\fR (read\-only)" +A limited view of the UNIX authentication database. The +following tables are implemented: +.RS +. IP \fBunix:passwd.byname\fR +The table is the UNIX password database. The key is a login +name. The result is a password file entry in \fBpasswd\fR(5) +format. +.IP \fBunix:group.byname\fR +The table is the UNIX group database. The key is a group +name. The result is a group file entry in \fBgroup\fR(5) +format. +.RE +.RE +.IP +Other table types may exist depending on how Postfix was +built. +.IP \fB\-M\fR +Show \fBmaster.cf\fR file contents instead of \fBmain.cf\fR +file contents.

For example, "\fBpostconf \-Mf smtp\fR" will output +all services named "smtp", and "\fBpostconf \-Mf smtp/inet\fR" +will output only the smtp service that listens on the +network. Trailing service type fields that are omitted +will be handled as "*" wildcard fields. + +This feature is available with Postfix 2.9 and later.
