Thanks for the heads-up. Yes, before I was indeed using clamd in a 'binary' way: infected mails were dropped on the spot. So maybe I really best turn that option off then. Not to start anything, but I've always believed that phishing detection isn't necessarily the domain of anti-virus software to begin with (I use an adapted version of SA for that); so it seems I'm better off not letting clamav do any phising detection any more. Which is fine by me. - Mark _______________________________________________ Help us build a comprehensive ClamAV guide: visit http://wiki.clamav.net http://lurker.clamav.net/list/clamav-users.html
