  Yes, i know. I use clamd for this. Implemented with 'clamsmtp' running
  on an extra postfix interface as documented on:

  http://www.postfix.org/FILTER_README.html#advanced_filter

  You can also plug in Amavisd-new there, but I don't need that as I only
  use ClamAV, and not a bunch of scanners in a row.

  You can also use clamd before the 'dot on a single line'. The performance
  questions I meant are these:

  Great, I do the same. (However, some may think this is 'hiding the
  problem' :-)). BTW: if you just drop, why do you care about before 
  or after smtp-time?

  Cheers,

  PS: Lots of viruses don't reach my virusscanner as I reject (5xx) mail with
  (exe|com|vbs|... etc ) attachments. Done via header/body checks, i.e.
  before the 'dot on a single line'.
