I really don't think an SMTP service extension would solve the problem - the problem is system administrators who decide they know better than the standards and set low timeouts.

Can you talk a little about those system administrators? How many are there of them?

A friend who did a little analysis said that 100.0% of the hosts that gave up too quickly and switched to the secondary MX were actually sending spam. IIRC "quickly" meant 45 seconds and he looked at around a thousand messages. Not a really big sample, but enough that I would look for counterevidence before assuming that the conclusion is wrong.
