I've removed the "sub.domain.com anything" entry, but all mail still
ends up in the catchall account.
Here's how I have some settings in postfix configured:
$mydestination includes $transport_maps, I have each domain that I
receive mail for listed in a transport maps table, mapping to
'local'. Prior to this exercise, I hadn't had need of the virtual
domain table at all.
So up until now, when I wanted to add a new domain and some users for
it, I would simply add the users to the mysql table, add the domain
to the transport maps, and make sure there was a directory with the
right permissions for the domain to create maildirs in.
So the question remains how to get the catch all working, only for
mails for the domain that have no existing user or alias.
