If SpamAssassin on your mail server is preventing spam mails from getting to your copy of The Bat!, then you should really disable it. Having two spam filters is not actually a good idea in most cases. If one deletes a spam or otherwise stops it from being seen by the other filter, then the other filter cannot evaluate it. Worse, if it if a statistical filter - a bayesian one like bayesit - then that filter will not learn about the spam's content and be able to update its filtering. The only exception for this that I can think of is the way The Bat! implements its plug-in architecture - which allows multiple filters, all of which report a score. You can then choose to act on the lowest (minimal) or highest (maximal) amongst the results, or to use an average from all filters. (See the anti-spam plugin filters preference page for details - it's not obvious at first!) This multi-plugin capability means that The Bat! would decide what to do after all filters have had a chance to look at the mail and report their findings. It also means that marking mail as junk would cause it to be analysed by multiple filters, improving the detection by all filters in the future. However, at the moment, I'm only aware of one free filter plugin for spam - bayesit - so this very nice feature of The Bat! goes unused as yet. Hopefully you can now see why the plugin architecture is so valuable, though. SpamAssassin should at most be marking suspected spam with some kind of subject alteration or header, and then you should let bayesit candle it as normal. If you're filtering on modifications made by SpamAssassin and not marking the filtered mails as junk for bayesit, it will never learn. To be honest, because of this I would tend to say that you should run only one anti-spam precaution - unless additional ones are also plug-ins for The Bat!. Anything else risks not correctly training the bayesit plugin. Of course, this could also be a failing in a beta of The Bat! - in which case, aren't you on the wrong mailing list? ;-) -- Best regards, Philip mailto:[EMAIL PROTECTED] Using The Bat! v2.02.3 CE on Windows 2000 5.0 Build 2195 Service Pack 4
