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.
Except that this thread started with a recommendation to block an entire AS, containing a reasonable number of networks. Recommendations such as that are only as credible as the source they are coming from, and knowing that the person making the request also believes that blocking all mail from gmail.com is a valid anti-spam technique probably results in a "different" credibility level than one might otherwise have.
