I'm having some trouble getting attachments right for all recipients,
and it seems like Apple's mail.app is the pickiest client at the moment.
It doesn't handle attachments that both Thunderbird and Outlook find
perfectly acceptable.

Since the code I'm using is currently ugly and embedded, before I trim
it down for posting could anyone who's successfully generated emails
with attachments received by mail.app let me know if they had any
problems along the way? Google hasn't given me much on this, but I'm not
feeling very creative today.

This method is used in one of my Plone products, and there is also a bit
of imap in there. But it is probably simple enough to extract the
attachment relevant parts....
