I sent an email to somebody with an hotmail.com address.
It gets bounced with a:
host mx3.hotmail.com [22.214.171.124]: 550 SC-001 (BAY0-MC1-F4) Unfortunately, messages from 126.96.36.199 weren't sent. Please contact your Internet service provider since part of their network is on our block list.
I am assuming that 188.8.131.52 is an mail.msu.edu address.
Did anybody experienced something like this before. What should I do? I
need to reply to that email.
