Mail Security Virus Mail gets through

vogonfleet
Hi,

we have a strange behavior on our Astaro which is acting as a mail gateway V 7.507
Antivirus is configured with single-scan.
In the past days there has been a mail wich is infected by JS/Redirector.IY, that has been
delivered to our mail server, the antivirus seems not to detect this one. 

The Avira Product on the mailserver has detectet the virus afterwards.

Is there any idea what could have happened.

    This is why we recommend having three layers of security: perimeter, server, client.  Normally, we prefer to have different products at each layer.  Astaro currently uses Avira and ClamAV, so it's a little surprising that the malware was detected at the server, but that may be because, in this instance, the server got a new pattern before the Astaro did.  I bet the same one would now be blocked by Astaro.

    Cheers - Bob
