Overview We have a _very_ small domain with a single e-mail server running Postfix and Courier IMAP. Using the examples in Courier IMAP, we created "userdb" so we could have virtual names (first.last@domain) mapped to existing local accounts. We use IMAP and Squirrelmail to access our local IMAP e-mail folders. Also, Postfix sends for both IMAP and regular e-mail. At this time, it receives e-mail properly to /var/spool/mail/<user> .

We are ready to "connect" Postfix to Courier IMAP (with the defined virtual names and local domain Maildir/ folders). In main.cf, I uncommented home_mailbox = Maildir.

Problem I understand that I must use an alias search - the man files, Postfix documentation, and the e-mail lists talk about this but they keep referring to virtual users at a virtual domain, not virtual users at a local domain.

Where and how do I tell Postfix to use aliases and map those to real accounts?

Thanks,
