[Declude.JunkMail] e-commerce counter weights
Most of my false positives are coming from e-commerce sites, where automatic email are generated after an order has been placed. What sort of counter weighting do you guys use to balance out these types of messages? I can't decide on anything to identify these types of messages with that spammers don't already try to fake. Any help would be much appreciated. Thank you for making YourNET Connection your connection to the world Jim O'Keefe Technical Support @YourNET Connection, Inc. [EMAIL PROTECTED]

We just use a negative weight list, and add new domains to the list as needed. Note that it's not a good idea to have any of your hosted domain in the negative weight list, or ISP domains such as aol, yahoo, msn, etc. as you'll just end up letting a lot of spam through that way. NEGATIVEWEIGHTLISTfromfile F:\IMail\Declude\negativeweight.txt x -25 0 We also use a "positive weight list", which is probably a misnomer since it add to the spam weighta better name would probably be greylist. We add known spam domains to this list. Similar to a blacklist, but we only add enough weight to hold on the greylist, while the blacklist has enough weight to delete. POSITIVEWEIGHTLISTfromfile F:\IMail\Declude\positiveweight.txt x 20 0 You'll probably want to adjust the weights to match your scale. We use the positive weight to put it just into the hold range, while the negative weight would take an email from the middle of the hold range down to zero.

As Darin responded you should use a negative weighted filter. I call mine compensatory.txt In it include REVDNS, CONTAINS, MAILFROM, etc. from the false positives that will counter weight the spam scores. As far a phrase that you could add for a BODY tag kinda hard. But they may work for you like 'Order shipped' , etc. I make compensatory.txt the first filter in global.cfg also; to be sure SKIPIFWEIGHT feature is used in the other filter files. -Nick Hayer Thank you for making YourNET Connection your connection to the world Jim O'Keefe Technical Support @YourNET Connection, Inc. mailto:[EMAIL PROTECTED] [EMAIL PROTECTED] [AUTOMATED NOTE: Your mail server [170.222.200.91] is missing a reverse DNS entry.
