Having exim have to figure out the backend imap server is what I was
trying to help you avoid by using Perdition.
If you haven't used Perdition, it's a fantastic IMAP/POP3 proxy that
can apply all kinds of rules on users to get them to the right
destination. Regular Expressions, Database lookups, many options.
Glad I was able to help.
