Hey Al, My hunch is that you're seeing the effects of greylisting (https://en.wikipedia.org/wiki/Greylisting) in action. I'm sure if you spoke with someone from the @msu.edu mail team that they could confirm specific instances.

It seems mostly resolved, but I don't think it's quite gone altogether. I haven't exactly quantified things, but I'm guessing upwards of 90% of incoming messages are arriving in timely fashion. However there have been several instances over the past few days when I was specifically waiting for a message to arrive, and noticed it took 45 minutes to an hour before I received it. I've had other users in my office report similar experiences. Can anyone else confirm this, or should all mail flow be back to normal as of now?
