email spoofing

[nunzeo]

I understand how spoofing works but there is something weird about this one. I have spam that looks like it came from myself with no internet headers, it looks like an internal message. Has anyone seen this before?

If you think it is internal, then test it by sending a internal spoofed email and compare them.

Start a new email -> click "view" -> "from field"

and put in a co-worker's email address in the "from" and "to" fields, send it - then check it out on thier PC.
