I use zcs 7 where I have domain1.com. I have to use split-domain because email@example.com is on my zcs server and firstname.lastname@example.org is on another qmail server.
I have set up domain2.com on my zcs server. I do not have any problems to send emails to email@example.com, but if I want to sent email to firstname.lastname@example.org (that reside on qmail server), the email is undeliverable.
Can you please help me howto configure the other domain (domain2.com) so that emails to domain1.com residing on qmail server be accepted?
