I have found that forwarding a message that has an infected zip file as an attachment ('Forward as attachment') allows the virus through, where forwarding the same message normally allows the virus scanner to search the zip file and find the virus. The first message made it through Astaro without a problem, but was caught by the AV solution I have running on the internal mail server, while the second was caught before making it to the internal mail server.
I am using the latest version (6.001) with a full home-use license.
