That comment dates back a few months to when I thought I'd have to
implement IMAP support myself.  Since then IMAP has been added to
Twisted (it's in CVS, but not in a release yet).  So now I can use
Twisted's IMAP protocol module.  The only thing keeping IMAP support out
of Hep at this point is my schedule - it's probably 10 or so hours of
work to get it up and running.

My feeling is that it probably makes sense to put any kind of filtering
into the Hep core, rather than tying it to POP3 or another protocol. 
Could you give me a better idea of what you could use Bayesian filtering
for?  I know basically how it's used for spam detection, but to the best
of my knowledge nobody is using Hep to read e-mail at the moment...

Thanks for being interested in the code.  I've been working on improving
the messaging.Message class, and improved address handling is going to
be part of this - I'll be checking it in this week.
