In that case, adding to ~/etc/access :

To:sales@xxxxxxxxxxxxxx		REJECT

etc. for each username you want to reject and rebuilding access.db should do
the trick.

However, I maintain that from my experience you'll find things easier in the
long run if you alias each of your valid e-mail addresses to the same
mailbox in your virtmaps file (instead of creating a separate mailbox for
each one) and turn off the catchall feature.

The day a spammer decides to do a *real* dictionary attack on your domain,
spamming every potential combination of 1 to 8 digits and letters
@yourdomain.tld, you'll see what I mean - it could result in literally
hundreds of thousands of spams ending up in your inbox!
