Like many people, I setup courier to use mysql for authentication. When I went through the setup, I decided to store username as [email protected] in the accounts table. Users who are not in the default domain, can login as [email protected] and they are good to go. This works well in most modern email clients, but some older clients, notably Netscape 4.5, can’t use this syntax and are unable to login.
