I have a customer that claims that her emails to our staff (with

@msu.edu and @rsgis.msu.edu) addresses are bounced.

She used to be able to email us all the time until about one week ago.

Everybody else can email us fine. We have a decent traffic of email on

daily basis.

I am pretty convinced that the problem is particular to them.

Nonetheless, I would like to have something more tangible to show them.

I was wondering if I could find if they are being blocked from MSU. I

remember in the past reading somewhere of IPs or blocks of IPs that

would be blocked from MSU for security reasons. Is there a way of

knowing what gets blocked from msu.edu?
