thanks in advance

All I can see is that the email originated from Idhao state University
email system it that helps.
No other information I think can be found form that.

Hi Dogene

Cut the header information that you used in your question and then go
to www.spamcop.com and paste it into the box. Press interogate and
spamcop will give you the link to report abuse. Click the link to open
your email and paste the same header into the body of the email. Idaho
State University should be very reactive to your mail.

Good Luck
