Problem
With the move from Nitix (which uses Qmail) to Lotus Foundations (which uses Postfix), can I customize email queue scripts?
Solution
Lotus Foundations allows you to customize the pre-queue filter. The following information is provided as a guideline. Should you require more in depth information about Postfix mail filtering, refer to the following external resource:
"Postfix Before-Queue Content Filter." by Postfix. Accessed 2008-01-25.
There are two commands that can be used to customize the Lotus Foundations email queue filter.
wv set [Email]PreQFilter = PATH
Where PATH is the location that contains the file to filter script. A template filter script can be found in /etc/postfix/policy_template.pl.tmpl. You may use this script to create your own pre-queue filters or you can write your own based on the information from the postfix website given above.
wv set [Email]PreQFilterTimeout = VALUE
Where VALUE is the numerical value for pre-queue filter to timeout. The default is 3600 seconds.
