129274 – [mail/dovecot] Patch to dovecot.sh.in to facilitate multi-instance configurations

no flags

Dovecot requires multiple instances with separate configuration files if your configuration requires differing settings across multiple addresses/ports.  This isn't an uncommon requirement (i.e., a single server with secure services via more than one hostname requires more than one SSL certificate; however, Dovecot only permits one SSL certificate per configuration).  Making copies of the current RC script and editting them to run the extra configurations creates the following problems:

- Port upgrades will not stop all running Dovecot instances prior to the deinstall/reinstall phase;
- Port upgrades that change the RC script result in outdated/broken RC scripts;
- Port deinstalls result in orphaned files;

Fix: The provided patch to dovecot.sh.in introduces the dovecot_extra_configs variable which specifies the configuration files of additional instances.  When dovecot_extra_configs is defined, the script iterates over dovecot_config and each extra config, starting, stopping or restarting each in turn.  The single-instance behavior (dovecot_extra_configs is empty) is the same as the current script.

I received no response from the maintainer to my original inquiry on 2008-11-11 about the issue of controlling multiple Dovecot instances.
