I don't see Serbia in the list of available countries... Supposed to be country code RS (republic of serbia). And it doesn't appear under R or S. How did you find it ?

Thanks!

A problem... I previously disabled amavis, so amavis isn't listed on the left menu.

When I go into Messaging / Security , I see Amavisd-new is green/on. Amavisd milter daemon is red/off.

I click Amavisd milter daemon red icon. It says "Starting......: amavisd-milter already exists using pid xxxxx..." ???????
