I setup an email server (postfix,dovecot, spanassassinm, amavisd-nre and clamav).
There is a website (https://www.webmail.us/testvirus
) which send kind of viruses to you to check security of the installation. From all 26 emails sent, I received 1 with the following text:
Test #23: (Non-Virus): Attachment with a CLSID extension which may hide the real
file extension. <B>This does not include the EICAR virus</B>, however your mail
server should still block this since the CLSID technique can be used to hide the
true extension of a malicious file. ***
If your mail server's virus scanner did not detect this email, it allows some
viruses through! Please note: This test message uses the EICAR test virus, which is
completely benign and contains no viral code. For more information see:
Is this a lack of clamav viruses database or did I do something wrong in the installation?
Any help is welcomed. Thanks
