ClamAV is not disinfecting mails

Hi there. I'm testing clam and noticed that when running the scan from the cpanel, and given that I purposedly sent several mails with the Eicar Test attached, I found that clamAV is detecting those mails as infected, but it is unable to disinfect (delete the attachment) or destroy (delete) those mails. Is this normal as these are Eicar Tests? or should I be worried about the impossibility to sanitize really infected mails in the future? May be this behaviour be due to a permissions issue? (clam can read, but cannot write)

I'm running the last Stable cPanel with the last Clam from the plugin manager, on a CentOS 4 VPS.

 

Yes, but I'm talking about the Clam Scan icon present in every cPanel account control panel. It allows you to scan the entire public_html dir or scan the allocated emails. when it detects infections, shows you a list with possible actions: disinfect, destroy, quarantine, ignore. The first two ones, appear to be correctly done after being selected, but a new scan will show the same infections again: clam is not disinfecting anything.

In the other hand, I sent emails with the Eicar test attached and they get to the inbox without even being noticed by clam.

 

Unfortunately I run CentOS 4 and I'm afraid that upgrading the box to CentOS 5 may possibly screw it.
