Hello, I followed the tutorial on http://www.howtoforge.com/virtual_postfix_mysql_quota_courier. It's a nice tutorial, BUT, the transport functionality doesn't work. I want to mail firstname.lastname@example.org. First the mail has to go to server A and than to server B (10.0.0.2) (mx records are right). When I set in the transport table --> x.com and smtp:10.0.0.2 <-- I got error messages saying the mailserver (server A) won't relay (relay access denied). When I put the x.com domain in the domain table, the mailserver complains about no virtual mailbox being available (which is normal). When I add this line in main.cf, it works -> relay_domains = x.com But why isn't it in the howto?
