I have a couple of users having problems with MSU mail being returned 
with "local delivery failed: retry timeout exceeded",
all of them today in the morning.

Since then, the emails had been sent and everything seems to be working 
fine now.
I am just trying to establish what was happening today earlier.
It was email from mail.msu.edu accounts sent to mail.msu.edu accounts.
They were sent with Thunderbird.

Did anybody had this type of problems?
