Αντικείμενο: [exim] EXIM not detecting virus emails
I'm having real problems with virus emails getting through my mail server. My
initial config consists of:

av_scanner = clamd:/var/run/clamd.exim/clamd.sock

acl_check_data:

  warn    condition  = ${if !def:h_Message-ID: {1}}
          set acl_m_greylistreasons = Message lacks Message-Id: header. \
                 Consult RFC2822.\n$acl_m_greylistreasons
  deny    senders = /etc/exim/lists/deny.senders


  deny    malware    = *
          message    = This message contains a virus ($malware_name).



I am getting /var/log/clamd.exim entries which implies that it's doing
something, but it's not detecting viri.

I have tried using Kaspersky with a wrapper script that I've written (I had
real problems with their Mail Gateway software which sits in front of EXIM)

I copied the syntax directly from the EXIM docs and amended to have:

  av_scanner = cmdline:\
               /etc/exim/bin/kasp_sweep %s:\
               ThreatName='(.*)'


However, when I try to use it I get:

2015-10-22 10:14:06 1ZpBwk-000EdW-Ui malware acl condition: cmdline: missing
virus name regex specification
