dovecot - Apr 2010 - Dovecot headers at start of text returned to KMail

The attachment show Kmail (kdepim-4.4.2-1.fc12.x86_64) accessing
an email from dovecot over imap.

From the wireshark-imap-trace.txt you can see at line 77
that the headers do not end cleanly "X-)". And at line 84
there is text from the headers that is not part of the body
"-Spambayes-Trained: ham". 

The email being access by dovecot is in:
1272011889.M384349P30156.f12barry.office.onelan.co.uk,S=6494,W=6606:2,S

Because of this bug kmail fails to show the message cleanly on screen.

The size of this file should be 6494 bytes (S=6494) but in your attachment it is
6519 bytes.  Did something insert a header into the file after dovecot received
it?  Perhaps this one, which (with a CR added) is 25 bytes, the same as the
difference between 6519 and 6494:
X-Spambayes-Trained: ham

As I understand it, once messages are under dovecot's control they must not
ever change at all.  Adding headers after delivery is forbidden.
