Over the past few days, I've received several spam emails coming from the addresses of a school district. I don't know much about email message headers, but since they contain numerous references like this:
Received: from ecb-mx-out1.example.com (ecb-mx-out1.example.com. [<ip_of_example.com>])
that makes me think the address isn't just being spoofed, since it looks like the SMTP server sending out the messages is coming from the school district. I don't know that for sure, however.
If I choose to contact the district's IT department, what information would be helpful for me to provide? Or, since it's clearly possible that the address was merely spoofed, is it just a bother if I contact them and it's more beneficial to them if I just ignore it?
I can post the full message headers if necessary, but I'll probably remove the school district's name/IP address if I do.
