I doubt it's an MTU issue, because lots of normal mail (including large messages) is flowing through perfectly well. Also, *all* of the machines (well, at least all of the ones I can tell from a PTR record) that are timing out are DSL, dial-up or cable modem machines. If it were an MTU issue, I'd expect to see the occasional "legitimate" mail server having problems.
