That sounds as if your are using that combination in your own
infrastructure. Sounds promising.

There is no hint in the Kaspersky documentation about such a file and
that setup step. I'll look at it.

That has been of course done. The amavis User is part of the klusers
group and kluser is member of the amavis group.

That will definitely break at least with the next system reboot. Those
kind of modifications aren't future safe.

Sure :)

That's added. As a secondary scanner the kavscanner has been configured
which fails as well, either because the logfile can't be written or
(when permissions to the log dir been changed) because the permissions
to the facade socket are not ok.

I am grateful for your reply. I'll again check things, especially the
/var/opt/kaspersky/apps/1463 file.

Kind regards
