Any header field can be faked. The only way to assure a message has passed my server is to have my server sign it digitally with the private GPG key of its postmaster. So anybody can download the corresponding public key and verify the contents (but i assume you all know how PGP or GPG work). And that is exactly what I intend to do. After a local mail user agent handed over the message to XMail, it should be passed on to my script verifying the validity (again, I will have to deal with this very carefully) and signing the message body. Then the message will get delivered via SMTP. I do similar things with incoming messages, as stated before. And if I understood the docs 'Custom domain mail processing' (Part 10) lets me do everything I need, except modify the message body. :-( So I need 'Domain message filters' (Part 13, you see, I _know_ the docs ;-) ) in the reversed direction. Excuse me if I am insisting, but can anyone tell me: can I modify outgoing mail message bodies (from my users to domains not handled by my server) or not ?
