Subject: Re: Watermarking


I really like the watermarking and find it useful and currently have it set to add 3 points to the SA score. I was wondering if there is an easy way to get it to appear as a SA rule rather than just adding to the score? It’s easier to explain if it is in a spam report than having to explain the SA score is 3 points high because of something you can’t see...

I was thinking of a SA rule based on a header that is set if the message fails watermarking? Then I can turn off the rule in MS itself and just let SA mark the mail.


Why would you wish to add 3 points to the score ? I thought that watermarking was to prevent backscatter plus the ability to bypass spam checks if the email originated from your server.  Would you not wish to reduce the score by 3 points if the watermark was valid; unless I am missing something ?

Thanks – Phil

Currently we don’t outright reject emails without a watermark as some of our users still send email via other means and we don’t have a way of preventing that at the moment. I could exclude their domains from watermark checking, but until then its easier to add a few points to the spam score and let that and the other SA ratings take care of it.
