Problem with the dangerous content check

[Amy Jin]

Hi everyone,

We are using MailScanner version 4.53.6. Most of the time it works well .

In order to invoke filename check, we set "dangerous content check =  
yes", but we met the followed problems with this option several times: 
we found the MailScanner hung up, we didn't know exactly what check was 
causing the problem, but after we set this option to 'no', it worked again.
Is there anyone has the same problem with dangerous content check? And 
is there a way to have filename checked without this option?

Regards.
