We had the same thing.  It's a bug in cyrus (off by one) so when they 
read their own null from the buffer they complain the message has a 
null.  We patched it.  We also sent the patch into cyrus.

dspam unwraps wrapped text in html or 'rich text' parts of messages to 
tokenize.  This leads to long lines that exceed the size of the buffer 
and exercise the bug.

There is a question of dspam design, and whether it might be ideal to 
work on a copy of the message and then send out the original with only 
the tags inserted (if body sig is on), but the cyrus thing is 
definitely a bug.
