The watermark feature examines all messages that have a null sender.  In 
sendmail logs these are the ones with:

"from=<>"

If gmail uses that approach to send vacation messages, and does not 
include the original message in the reply, then it will trigger the bad 
watermark action.   So if you want to be able to receive these and still 
use the watermark feature, maybe you could just add 2 or 3 points for a 
bad watermark.
