I am a little confused about what is going wrong here.
Or more specifically why the real-server (exchange) is rejecting the login
even though the password hasn't been supplied.

I suspect that it doesn't like the way that perdition is concatenating
its string-literals. Is there any possibility that you could give me
IMAP access to an exchange server to test against? I wouldn't necessarily
need a valid login to check this problem.

I will check through the relevant RFCs, but yes, that sounds like a good
idea to me. Currently perdition doesn't understand the OPTIONS command and
is rejecting it (and getting confused too!) .
