Arch Users, if you are using Postfix on Arch Linux and if your Postfix setup utilizes either cdb, ldap, lmdb, mysql, pcre, pgsql or sqlite as data backend your setup will cease to work once you've applied the recent 3.5.9-1 packages.
As of this package release Arch Linux has begun to use Postfix' feature to load database drivers dynamically. You will have to install the aforementioned database drivers as optional packages to continue using these database types. Use the pacman-command to list optional Postfix packages: # pacman -Ss postfix- extra/postfix-cdb 3.5.9-1 Fast, easy to administer, secure mail server extra/postfix-ldap 3.5.9-1 Fast, easy to administer, secure mail server extra/postfix-lmdb 3.5.9-1 Fast, easy to administer, secure mail server extra/postfix-mysql 3.5.9-1 Fast, easy to administer, secure mail server extra/postfix-pcre 3.5.9-1 [Installiert] Fast, easy to administer, secure mail server extra/postfix-pgsql 3.5.9-1 Fast, easy to administer, secure mail server extra/postfix-sqlite 3.5.9-1 Fast, easy to administer, secure mail server Once you've installed one or more of the optional packages you will find a new directory dynamicmaps.cf.d in Postfix' configuration_directory. It will contain one file per database type that sets which database driver Postfix should load dynamically: # cat /etc/postfix/dynamicmaps.cf.d/postfix-pcre.cf pcre postfix-pcre.so dict_pcre_open Reload Postfix and you are done.
