I started up Mail on my iMac for the first time, just to see what a
modern MUA does.

It first asked me for my address and my password.  Then it tried
doing...  something based on that address -- I'm guessing it probed for
pop3 and imap ports.

Then it said it couldn't find anything, and asked me to choose an
incoming mail server.  It defaulted to pop3, but had three other
choices: IMAP, Exchange 2007, and Exchange 2007 IMAP (!).  Weird.

Anyway, I chose IMAP, and it presented me with a new dialogue saying
that the certificate was invalid, so it had contacted the imaps port.
(Since the server in question doesn't have an open imap port.)  I
clicked "continue", and it presented me with an overview of everything,
and under the "IMAP" section "ssl encryption" was ticked on.

So I'm guessing it probed imaps and then imap, just like my clever
plan.  And then stored the result.

Which reminds me.  Stuff like this should be stored.  If nnimap has
determined that server X is an imaps server, or whatever, then it
shouldn't have to probe every time Emacs is run.

Does Emacs have any good mechanism for saving data like this?
