I get this in email today, which first off, they are not supposed to email, they are supposed to open a trouble report, anyway,....hows this for descriptive?

Subject Line: weird stuff coming into e-mail

Here's the email itself: had a couple weird messages come thru this morning.

Also had an undeliverable message - - which I didn't send that I know of

can you shed any light



Now just WHAT does that tell me in order to troubleshoot the issue??
