Thank you for the response Michael.

I'm not thinking this will give me any advantage at all. Especially 
given the behavior of the amavis truncating the message close to the 
threshold prior to scanning.

If this scanning behavior looks to cause an issue with some messages, I 
can deal with those edge cases as they come up.
