You're going to end up with filenames longer than your file system can
handle. I can't remember what the actual limit is but I have run into it
before and ended up with files that I could only access if I shortened
the mount location.
Greping the subject out of the mail is as easy as pie though and will
give you the filename & subject together.
grep ^Subject: /path/to/dir/holding/maildir
I use that for very quickly checking that my spamtrap spam really is spam.
I'm afraid I can't actually offer any real help other than warnings and
an easy grep :P I need several hours and a caffeine I.V. to do anything
with regex.
