[Dovecot] Creating a "default" domain

[Charles Sprickman]

Hello,

I'm setting up a test server to work through the issues involved in 
bringing a bunch of vpopmail/qmail/courier users into a postfix/dovecot 
server.  So far I'm seeing lots of info to aid in the transition.

One thing I'm lost on is that since Dovecot is providing all the auth 
mechanisms rather than vpopmail, I'm not sure how to emulate a particular 
vpopmail behavior we rely on.

Vpopmail allows for the concept of a "default" domain for authentication. 
So if I have a bunch of domains, and one is "example.com", users in that 
domain can login with only the username part of their id (ie: "john") 
rather than supplying the domain (ie: "john at example.com").  I need to 
continue to offer this unless I want to walk a few hundred users through 
reconfiguring their mail clients. :)

Any pointers?

Thanks,

Charles
