I've notice over the last several weeks a number of periods of time where MSU's system has been tempfailing incoming email, generally with messages about too many simultaneous smtp connections. We've got a number of systems that send mail to people in our departments, and I've seen times when the queue to send those emails builds up while those issues happen. My guess is the retry limit exceeded are for those that get particularly bad luck with when the attempts come in such that they hit a number of attempts with this tempfail. I've been meaning to contact it services when I next saw this problem because I had a number of people in my department wondering what was going on, but of course, I haven't actually seen the problem since then :).
