wrong hard-coded socket location in amavisd-release

[Dominic Raferd]

In amavis 2.11 the utility amavisd-release has a hard-coded location for amavisd's unix socket at line 90 as '/var/amavis/amavisd.sock' which is not aligned with the location actually set in /etc/amavis/conf.d/25-amavis_helpers where it is "/var/lib/amavis/amavisd.sock".

This causes amavisd-release to fail when trying to release a quarantined email for delivery.

Changing the hard-coded location in /usr/sbin/amavisd-release at line 90 to match the setting in /etc/amavis/conf.d/25-amavis_helpers fixes the problem.

The previous version of amavis (2.10), used with Ubuntu 16.04, did not have this problem I think. I believe it is new with the version installed (using apt-get) with Ubuntu 18.04 (i.e. 2.11). I have not tested intervening distros.

This bug is an incompatibility between the setting in debian package of amavis 2.11 which has:

/etc/amavis/conf.d/25-amavis_helpers at line 25:
    $unix_socketname = "/var/lib/amavis/amavisd.sock";
/usr/sbin/amavisd-release at line 90:
    $socketname = '/var/amavis/amavisd.sock';

As directory /var/amavis does not exist, the only realistic solution is to change the setting in amavisd-release.

The problem arises because in Debian (and hence Ubuntu), $MYHOME is hard-coded to /var/lib/amavis whereas in the default installation, it is /var/amavis. And amavisd-release does not seem to use the $MYHOME setting.
