FYI, WebCT (Campus Edition) also triggers this problem.

If an instructor has their WebCT mail forwarded to their Cyrus account, 
and a student posts a message containing a huge attachment within WebCT 
for that instructor, upon delivery to Cyrus that message will blow up as 
you describe. I found out that WebCT encoded such attachments as one 
long line and not nicely folded text like most clients do. I reported 
the problem to them and they said it would be addressed in some future 
release, but don't know when.
