Note that if you're using procmail, and you have your procmailrc set up
| /usr/local/bin/hammie.py -f -d
* ^X-Spambayes-Classification: spam
| $RCVSTORE +spam
* ^X-Spambayes-Classification: unsure
| $RCVSTORE +unsure
... other message handling ...
Then the duplicate header won't matter worth a damn. procmail will still
see the 'spam' header, and punt the message into the spam folder.
