Can I configure postfix to relay outgoing mail to different ISPs based on To: header?
Why? Suppose I have different accounts with different ISPs and s u b - s c r i b e to different mailing lists via different accounts. (Apparently I can't use that word above without having my mail rejected by the mailing list manager, hence the funny spacing) It would be nice to teach postfix that mail to [EMAIL PROTECTED] should be sent as though it were from [EMAIL PROTECTED] and relayed through isp1.com's mail server, same for list2, user2, isp2, etc. If I teach postfix all this nonsense once, I don't have to keep it straight myself :-). Just curious if it is possible...
