As to his decision to block Gmail (or any other freemail provider),
everyone with sufficient knowledge in the field knows that these
operations are prolific and habitual sources of spam (via multiple
vectors, not just SMTP; Google accounts for more Usenet spam hitting
my filters than all other sources combined).  It's thus not at all
unreasonable for some operations to revoke (some oor all of) their
privileges by way of self-defense.  

And, even if it *is* unreasonable, well, his network, his rules, right?

"I block all SMTP traffic from IPV4 servers (clients?) which have odd 
numbers in the third octet." might not be a good idea for a high volume 
mail server with clients, but if it's your network, go for it.
