email address and user accounts

[MightyMe]

I'm setting up a mail server for the first time using Postfix and Dovecot on Ubuntu 10.04. So far I have managed to send and receive mail between user accounts on my example domain, for example mail between john1@mydomain.net and john2@mydomain.net.

How do I connect their real email addresses to the accounts and send mail between john.smith@mydomain.net and john.jackson@mydomain.net? I have not set up LDAP authentication yet.

Any help would be much appreciated.

Use aliases. Edit as root the file /etc/aliases and add entries like this:

john.smith:          john1
john.jackson:        john2

Then run (again as root) the command "newaliases" to update the alias database. See "man aliases" for more details.

Works like a charm. Thanks.
