I agree in some respects. As a former Declude user I found that very effective tool required more and more of my time, administratively, to the point that I wound up blowing an hour or so per day tweaking the thing. The solution I found -- and I am a general-ISP in the sense that I serve all sorts of customers -- was to implement a well thought-out Bayesian filtering system. One that included an automatic whitelisting feature that builds itself (althought I also built in a manual whitelister my clients could use... and hardly ever do). The thing also supports blacklists, but the only one I use is the one William Van Hefner -- from this list -- posts. I could do without it but I found it to be reliable. As for 1 out of 100k FP's, I never, ever get customer calls about missing mail anymore. And believe me, they aren't shy about that. Bayesian filtering isn't for everyone. You have to live with a few weeks of hell before the system runs on autopilot -- but for this one (free) tool, it does so permanently once trained. It absolutely amazes me why neither the people at Ipswitch or Smartertools look at ASSP's feature set and copy at least part of it. The auto-whitelisting alone (anyone you send auth'd mail to gets added to the whitelist, among other things) is a giant benefit to any antispam system. -- --mattRobertson-- Janitor, MSB Web Systems mysecretbase.com To Unsubscribe: http://www.ipswitch.com/support/mailing-lists.html List Archive: http://www.mail-archive.com/imail_forum%40list.ipswitch.com/ Knowledge Base/FAQ: http://www.ipswitch.com/support/IMail/
