I have postfix/ispconfig 3/centos/etc. seemingly properly configured but I am running into a problem.
I have setup an email account in the system, email@example.com
I have properly set up my dns such that I have and A record for
with an mx record for
So, I expect that any mail that goes to firstname.lastname@example.org
would be forwarded to mail.domain.com (which are on the same machine), but instead postfix returns a 550 response and kicks the email back.
Do I have to set up another email domain in ispconfig and do an alias on each user, or is there a more global way to do this? I explored the $mydestination variable in postfixs main.cf, but from my reading, it appears that the right way to adjust these sort of things on ispconfig 3 with mysql is through the ispconfig interface itself
Any help would be appreciated!
