to set up postfix for virtual users is one thing and off topic here.
You do not need to use virtual users in cyrus as well. This is totally 
independent. If your IMAP user names have their own naming schema and 
that is independent from your SMTP mail addresses, which is totally OK, 
you can stick with that.

Mapping between virtual SMTP mail addresses and IMAP users does postfix 
for you.
