I installed this producta couple ofmonths ago, however I have to say the spam filter seems pretty ineffective in that I am inundated every day with spam fromMAILER-DAEMONs or Postamasterfor exampleMany of these type of spam emails get through"Mail Delivery Subsystem" <MAILER-DAEMON@smtp1.coolspot.de>"Mail Delivery System" <MAILER-DAEMON@smtp.tele.fi>"Mail Administrator" <Postmaster@ezweb.ne.jp>I have the collborative filter set to maximum and the message agressiveness set to maximum. I constantly junk these email manually every day.Having come from K9 that intercepts these emails, I find this product a bit ineffective.Any ideas other than using K9 again.(using Zone Alarm Internet Security suite 6.5.722
