ClamAV scans email ISPConfig 2

I've created a user email account and I enabled the "MailScan" option in the "Advanced Settings" and the "Antivirus" option in the "Spamfilter & Antivirus" settings.

However when I send and receive email I don't see in any part of the email a message saying that the ClamAV has scanned the email. Isn't it supposed to show that message writen in the email message? If not, how do I see if my ClamAV is in fact scanning all the emails that are being sent and received?

Thank you in advance.

Kind Regards.

 

You can test ClamAV with the Eicar test virus: http://www.eicar.org/anti_virus_test_file.htm

 

Thank you!
