Hi, we try to use the Avast! scanner with amavisd. There are a couple of
scanner definitions out there, but regardless whether we use
['AVAST Antivirus - Client/Server Version', '/bin/scan',
'{}', [0], [1],
qr/\t(.+)/m ],
or
['avast! Antivirus daemon',
\&ask_daemon, # greets with 220, terminate with QUIT
["SCAN {}\015\012QUIT\015\012", '/var/run/avast/scan.sock'],
qr/\t\[\+\]/, qr/\t\[L\]\t/, qr/\t\[L\]\t([^[ \t\015\012]+)/ ],
we always get the following permission errors:

The Avast processes run under the user avast which is member of the
amavis group. But this seems not to be enough? It seems that there is no
option to have the avast processes run as user amavis, so we need to fix
the permissions.
Maybe other avast users can recommend a setup !?
