Setting up email routing with exim

From Eventum

This describes how to set up the Email Routing Interface with the Exim MTA.

Address Extensions

Address extensions can be enabled with the local_part_suffix option in the Exim configuration file. If you were to e.g. route mails of the form "issue XXXX" and "issue" to the users eventum and archive on your system add this line to /etc/aliases

 issue: eventum archive

and these two lines to the aliases router section of the Exim configuration file:

 system_aliases:
    ... 
    local_part_suffix_optional
    local_part_suffix =  *
