We have some e-mail addresses for our scout troop. Since the recipients change from time to time and also non-digital affine people should change the redirections, we used the alias function in the web interface.
For example, email@example.com should redirect to firstname.lastname@example.org and email@example.com.
This works as it should, and it’s easily configurable.
But sometimes it is difficult to guess, which address was originally used. That’s why I like to add the original recipient to the subject of the mail.
So if someone writes a mail (To or CC or BCC) to firstname.lastname@example.org, the mail should be redirected to email@example.com and firstname.lastname@example.org with the new subject “[pfadis] old subject”.
My first try was filtering, but it seems, that alias mails will be redirected before filter execution.
Does anybody have another solution for this problem?
