Well, I'm trying to make sure that rAndOm case in email addresses
doesn't throw of the matching - it's quite common for people to write
email addresses as First.Last at Company.Com - the RFCs that I've seen
(can't double check, on a plane right now) seem to indicate that you
can't rely on the headers being lowercase - so even preprocessing the
configured email addresses might not be enough.
I guess we could selectively force some of the headers to be stored as
lower case - Received, X-Original-To, Envelope-To in my case - but that
seems wrong somehow.

Open to better ideas...
