MailScanner not removing virus even though it was found?

[Giampiero Raschetti]

I'have just upgraded to the latest mailscan 4.22-5 from 4.13-x and
I'm registering exatly the same problem:

In the configuration file there is absolutely no changes from the default
parameters.
MailScan 4.22-5 has been installed from RPM pakage and it is working using
McAfee antivirus.
Every other functionality works fine.

Need to investigate more deeply on this quest.
