Norman Sandbox and MailScanner

I use MailScanner with Norman Virus Control.
Norman has it's Sandbox feature which is able to find virussen not in the 
definition files.
see: http://sandbox.norman.no/

When i send the eicar test file, MailScanner will detect a virus.

When i send a real virus (Trojan.Brepibot.V) not detected by Norman (because 
for this test i use older definition files),
but which is detected by Norman Sandbox (as W32/Malware),
MailScanner does not detect any virus.

Any ideas?

Thanks
