Since version amavisd-new-2.7.0(-pre*) it is possible to use a
native Sophos protocol SSSP to connect amavisd to their daemon savdid.
Just start it with 'savdid -d' and configure it to listen on
some socket such as /var/run/savdi/sssp.sock, or an an INET socket,
then add the following to the @av_scanners list amavisd.conf
and restart amavisd:
['Sophos-SSSP',
\&ask_daemon, ["{}", 'sssp:/var/run/savdi/sssp.sock'],
# or: ["{}", 'sssp:[127.0.0.1]:4010'],
qr/^DONE OK\b/m, qr/^VIRUS\b/m, qr/^VIRUS\s*(\S*)/m ],
With earlier versions of amavisd the only choice to use a daemonized
Sophos scanner is through a Sophie daemon:
['Sophie',
\&ask_daemon, ["{}/\n", 'sophie:/var/run/sophie'],
qr/(?x)^ 0+ ( : | [\000\r\n]* $)/, qr/(?x)^ 1 ( : | [\000\r\n]* $)/,
qr/(?x)^ [-+]? \d+ : (.*?) [\000\r\n]* $/m ],
Actually savdid daemon can also emulate a Sophie protocol so it should be
usable with amavisd 2.6.4 and earlier, but I never tried this combination.
Make sure amavisd has r/w access to a savdid socket, and that savdid has
read access to amavisd work area ($TEMPBASE, typically /var/amavis/tmp).
Running both under the same UID makes this easier, but is not a requirement,
the same can be accomplished by adding a sophos UID to amavis group.
