Email attachments

[Steve Holden]

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.

Note that this is an important application: it sends out the invoices 
for PyCon sponsorship!

regards
  Steve
