I setup with the instructions from qmailrocks.org. Everything was working for months but I cannot receive email anymore on the virtual domains. There were some changes made to sql that I'm guessing screwed things up.
Here's an example that'll probably better illustrate the problem.
qmail Server: dom.com
Virual Domain on qmail server: virdom.com
Other domain outside of network: other.com
email@example.com can send and receive mail to firstname.lastname@example.org.
email@example.com can send mail to firstname.lastname@example.org.
email@example.com can receive mail from firstname.lastname@example.org.
email@example.com cannot receive mail from firstname.lastname@example.org
email@example.com can receive mail from firstname.lastname@example.org.
Thanks in advance,
