Ok. I may not make much sense... (NOTE. I am not trying do anything particular, just wondering about the general idea of rewriting).
When sending mail in the following way: Host1 ------->Host2 and we want it to appear to come from Host3. Can Host1 rewrite a message header and then send it to Host3? Isn't possible that the Host2 smtp server would first do a host lookup or some kind of comparision from where the message arrived versus what the mail header says and reject if they aren't the same?? I guess I am asking isn't possible that the mail server on Host2 will not accept rewritten message headers. Perhaps I misunderstanding the concept of rewriting...a clarification from a mail guru in down to earth language or a good weblink would be appreciated. -walter
