I'm getting hit by a LOT of people using my mail forms (I think) to route a
lot of spam through my server. I see some of them come back to me, but am
not sure how much is going out to the real world. What's the best way to
block people injecting BCC: or CC: into my mail forms to spam people? My
attempts at replacing the BCC or CC aren't working, and my attempts to kill
the PHP script when a BCC or CC is detected is failing. How are others
protecting their php mail() forms from this?

Thanx,
Wm
