Let's say I have domain1.com, domain2.com and domain3.com.
I have a bunch of local users for these 3 domains (domain2.com and domain3.com are alias domains for domain1.com, so firstname.lastname@example.org will be delivered to email@example.com maildir).
I have noticed I can define a domain as 'local' or 'virtual' or 'relay'.
What I want: to be able to manage all of the 3 domains from postfixadmin interface, without deleting the system users. Is this possible?
I have postfix 2.6.5, maildrop 2.2 and dovecot.
