Homebrew PCBs

Does anyone else get this message?  I am on digest mode and it seems that if 
the number of messages exceeds about 18 or 20, I get this business.  The 
digest itself seems OK, but I'm wondering where the problem is coming from. 
  I use AVG, and it doesn't seem to find any issues with the digest.

TIA,
Donald.
