These tables are 19 usually in <b>dbm</b> or <b>db</b> format. Alternatively, lookup tables can be spec- 20 ified as NIS+ databases. 21 22 To find out what types of lookup tables your Postfix system supports 23 use the "<b>postconf -m</b>" command. 24 25 To test Postfix NIS+ lookup tables, use the "<b>postmap -q</b>" command as 26 described in the SYNOPSIS above. 27 28<b>QUERY SYNTAX</b> 29 Most of the NIS+ query is specified via the NIS+ map name. The general 30 format of a Postfix NIS+ map name is as follows: 31 32 <b><a href="nisplus_table.5.html">nisplus</a>:[</b><i>name</i><b>=%s];</b><i>name.name.name</i><b>.:</b><i>column</i> 33 34 Postfix NIS+ map names differ from what one normally would use with 35 commands such as <b>niscat</b>: 36 37 <b>o</b> With each NIS+ table lookup, "<b>%s</b>" is replaced by a version of 38 the lookup string. There can be only one "<b>%s</b>" instance in a 39 Postfix NIS+ map name. 40 41 <b>o</b> Postfix NIS+ map names use "<b>;</b>" instead of "<b>,</b>", because the lat- 42 ter character is special in the Postfix <a href="postconf.5.html">main.cf</a> file. Postfix 43 replaces "<b>;</b>" characters in the map name by "<b>,</b>" before making 44 NIS+ queries. 45 46 <b>o</b> The ":<i>column</i>" part in the NIS+ map name is not part of the 47 actual NIS+ query. Instead, it specifies the number of the table 48 column that provides the lookup result. When no ":<i>column</i>" is 49 specified the first column (1) is used. 50 51<b>EXAMPLE</b> 52 A NIS+ aliases map might be queried as follows: 53 54 <a href="postconf.5.html#alias_maps">alias_maps</a> = <a href="DATABASE_README.html#types">dbm</a>:/etc/mail/aliases, 55 <a href="nisplus_table.5.html">nisplus</a>:[alias=%s];mail_aliases.org_dir.$<a href="postconf.5.html#mydomain">mydomain</a>.:1 56 57 This queries the local aliases file before the NIS+ file. 58 59<b>SEE ALSO</b> 60 <a href="postmap.1.html">postmap(1)</a>, Postfix lookup table manager 61 62<b>README FILES</b> 63 <a href="DATABASE_README.html">DATABASE_README</a>, Postfix lookup table overview 64 65<b>LICENSE</b> 66 The Secure Mailer license must be distributed with this software. 67 68<b>AUTHOR(S)</b> 69 Geoff Gibbs 70 UK-HGMP-RC 71 Hinxton 72 Cambridge 73 CB10 1SB, UK 74 75 Adopted and adapted by: 76 Wietse Venema 77 IBM T.J.
