I've noticed the several Viruses are getting through my mimedefang Filter. One sample is a copy of Bounce message including the Headers, and Multi part MIME Attachments Containing the . The Virus is detectable with Clamscan, but not with antivir. I am not certain if this is an issue with the message structure, or MD 2.43. Since May 10th, I have received six viruses which were not detected with MD 2.43 (previously I had no issues with MD virus detection).

Has anyone else received a virus coming through their installation lately? I realize that the message is actually a resend of a 'original' (or better yet, spoofed) message. But the Attachment Type (message.scr) is still not permitted. Is it because of the the obfuscation of the message, or is there more filtering that was required in order to capture this email?

While I can repeat this one message getting through the MD Scanner (although it is correctly detected as spam) and receive a warning from my PC Scanner, I don't want to rely on my Laptop's AntiVirus Scanner. I am wondering if the assortment of Mime-Types is the Latest formula from our friends the Hackers. Here is part of the original message for the formatting information:
