Er...?

I have a question for the internets. Has anyone else been getting messages from a DSL-SIA-INFO @ psu.edu? One of my addresses recently was picked up by spammers, but the vast majority of the messages I've been getting lately have been some variation of "Please remove me from this list". Some of them are even threading in gmail. I've opened a couple and they have nothing malicious in them, just a body with a please remove variation and even some with people reminding others not to hit "reply all." The names they're coming from sound legit as well. One even came from a Blackberry. I'm a bit baffled, and almost tempted to e-mail one of the people and ask if they were put on in a similar fashion.
