I had my server set up with generic aliases in /etc/courier/aliases/users, which worked fine. But today I wanted to host some new domains, where addresses overlap.

What I need is that [email protected] goes to account "dv", but [email protected] goes to account "d2". So I set up a new file containing fully qualified addresses ([email protected]: dv) instead of the previous dave: dv.

But somehow, courier-smtpd doesn't accept mail to these addresses anymore. makealiases -dump prints all the aliases the way they should be.. so i'm a bit stuck.
