Yeah, I've had MTU problems with mail in the past, but they've always
caused timeouts on inbound mail, never outbound mail. Unless gmail is
trying to send you a reply packet larger than 400B, and that's what's
timing out, but I can't imagine a reply larger than 400B in a standard
SMTP conversion unless there's a large rejection message.
