Cyrus IMAP version: 2.1.9

I did some testing with different Eudora versions:
- Eudora versions up to and including 5.1 send mail with these erraneous
nested MIME boundaries. (Tested version 4.3.2, 5.0.2 and 5.1)
- Eudora versions 5.1.1 and later seems to fix this MIME boudaries issue.
(Tested version 5.1.1 and 5.2)

This situation can be quite easily tested just by sending mail with
Eudora. The mail has to have two MIME parts, one attachment and the other
is multipart/alternative (eg. text and html versions of the mail).
