We are a small charity organization running ExIM for our emails. Is there a proper way to configure ExIM to append links to our facebook and twitter profiles to every outgoing mail?
I found this ExIM wiki page Modifying message bodies, which states "you shouldn't do it" and offers as only approach using
transport filters and external scripts.
What would you recommend?
Bonus: Would it also be possible to add the newest entry of an rss feed to the signature?
