Virtual domains and user@domain1.com and user@domain2.com

[Jim Norton]

Ok I need to clarify.

I don't have a "joe" mailbox yet. I would like to be able to have two 
"joe" mailboxes called for example:  joe at virt-domain1.org and 
joe at virt-domain2.org.

In my current usage of Cyrus IMAP I've not been able to do this because 
I've been creating users with a command like  cm user.joe ..... Without 
the FQUN.

Then through the Postfix config files I tell Postfix which virtual 
domain joe belongs to.

So currently "joe" can only exist in one virtual domain.

My question is how do I go about setting up users in Cyrus IMAP and 
Cyrus SASL so that I "could" have a user "joe" in multiple virtual 
domains?

Thanks for the replies everybody...
