I forgot about these. Gotta make a copy of the data and lowercase it
character per character, but it would work. Thanks.
(you can tell it's been a good 5 years since I've had to program in C :-D)
I'll dig in the exim code, it may already have a function to do this or do
caseless header matching.

I've been scanning through RFC 2822 and it seems to confirm that I indeed
need to accept "Message-ID:" as well as "Message-Id:"
I'll add support for that but it's not critical, very few mails use
alternate case in header names, and if my code can't parse a header, nothing
really bad happens anyway.
