I have the following situation. The company have a few offices all over the country. They have one hosted email service provider that host thier domain for all offices. Now we have a caching mail server at the largest office, running postfix. IT use fetchmail to download the mail for the people at the office and drop it in local mailboxes. The people then read it from that server via pop3/IMAP. THe email clients also use the caching server to send mail. So local mail is delivered directly and only external mail is relayed outside. The problem now is that mail destined for someone at one of the other branches are bounced by the caching server as no local mailbox exist. (Same domian, so postfix try local delivery) How can I configure postfix to relay mail for those adresses via the external (hosted) mail server? I have been googling and reading posfix docs and so far I have only seen the fallback_relay option, but I set this to the external server, but it still bouces the mails. Any ideas, links, examples please?
