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?

Follow the recommendation! You shouldn't do it – mailq Nov 26 '11 at 20:17

You gave the answer to your question. This is the answer: Modifying message bodies.

Mailservers are meant for receiving, forwarding, sending and storing mail. They are not responsible for changing the content of the body. And even for headers there are strict restrictions where a mailserver should only modify the headers required by RFC 5321.

Do you have a suggestion for our usecase? – Framester Nov 26 '11 at 22:50
@Framester Sure. Make it mandatory for the users to add it into their signatures in their mail client. This is where it belongs to. – mailq Nov 27 '11 at 0:22
