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.
