RE: Text Body Line to Long RFC 2821
So, let me get this straight. You don't want your firewall to conform to the RFC's, yet you complain when Exchange doesn't like it? Unless you have a very, and I mean VERY, brain dead firewall, there is no reason that it can't enforce text wrapping. I don't buy that having the firewall enforcing the wrapping limits will open you to buffer overflows, either. I'm interested in what kind of firewall it is, so I know to never buy one. -- Roger D.

Messages coming _from_ your Exchange server destined for an external recipient make you vulnerable to a buffer overrun how?
