Hi

I use amavisd 2.10 and clamav 0.99 with sanesecurity.

If the mail is detected as infected by clamav with one single infection
the above map is working.

I see in the logs that the virus names apparently are not passed to
amavis and the @virus_name_to_spam_score_maps not work in this multiple
infection case

What I'm missing?


OK, the problem was in the amavisd.conf at the @av_scanners section: don't know why, but missed the /m (Treat string as multiple lines) option

['ClamAV-clamd',
  \&ask_daemon, ["CONTSCAN {}\n", "/var/run/clamd.amavisd/clamd.sock"],
  qr/\bOK$/m, qr/\bFOUND$/m,
  qr/^.*?: (?!Infected Archive)(.*) FOUND$/m ],
