How does mail washer work? I mean, does it require days/weeks of learning your friends, etc.? My big problem with personal antispam filters is I find I end up looking through their junkmail to see if there are any false positives. So from a time point of view, it would be easier just to delete the annoying email. Also for me, I want my spam blocked before it reaches my network (as there are thousands of emails coming in per day). Currently we use a service through Vox Datapro (which costs about R2500 per month), but is very effective for the hundreds of users on my network... until this year. I have seen an increase in spam from stuff previously slipping through maybe once every 2 weeks, to now almost daily crap coming in. Any suggestions for a better ISP based system? I guess I need to start deploying another level of antispam as well.
