This seems like an easy thing to do but I'm still a beginner. I have a postfix installation w/ dovecot, SA and postfixadmin. In addition to a few virtual domains, I have the linux box in front of an M$ exchange 2003 server acting as a content filter. All the emails going to legitimate accounts in that domain are relayed after filtering. I'd like to also have that (relayed) domain to have a couple of additional accounts which would be accessed through the IMAP server like the rest of the virtual domain's accounts.
postconf -n | grep relay relay_domains = mysql:/etc/postfix/mysql_relay_domains.cf relay_recipient_maps = hash:/etc/postfix/relay_recipients relayhost = 192.168.0.5:25 /etc/postfix/relay_recipients is in the form of us...@example.org OK us...@example.org OK us...@example.org OK us...@example.org OK and of course postmap /etc/postfix/relay_recipients I've created accounts (honey pots) in postfixadmin and put them in /etc/postfix/relay_recipients but I get 550 5.1.1 User unknown (in reply to RCPT TO command) from the exchange server.
