“avast! Antivirus: Untestable Mail Detected”
Is what I keep getting in my inbox. Is there anyway to stop this? Any idea what is causing this? It seems like the emails always have a large (~2mb) attachment with them. Also I’m not sure if the email are making to their final destination, although the email says “avast! Action: Delivered”
Ok I have now tested and the email ARE reaching their destinations. Still no idea why these warning all of a sudden started coming. Any guesses would be appreciated 
Please try restarting the “avast antivirus” service (Control Panel → Administrative Tools → Services).
Thanks
Vlk
Thank you Vlk for the response, you are the most helpful Avast guru I have ever had the pleasure of dealing with.
I had restarted my server a few days ago and have still been receiving the messages. So today I just restarted the service you suggested and a few minuets later I got another one of the messages 
I get the occassional one of these (one every few days to a week - very low given the volume of mail we process). Is there an explanation of why it is untestable, so I can try preventing them from occuring? I’m in two minds as to whether I should allow these to progress through the system or not.
If the untestable email is infected and I let it through, it’s probably me who will carry the can!
Cheers,
Mark

twilson, is this email legit, I mean, are you expecting it or it is a spam?
I’m checking with the people that received them, they are currently at lunch. Why would it matter, if it was spam I would want it checked before it was delivered.
Thanks for the quick reply
Tony
I wish that too. Sorry I’m not an expert on Server version…
