u could set up a filter that rejects email that doesn't have the right From
header,
however someone that sends email with a correct envelope, tends to also have
a correct From header as well. I am not sure this will have the desired
affect. u would be better off locking the server down to ur own IP's unless
u have external users, then I would recommend SMTP AUTH

Maybe in order to understand mankind, we have to look at the word itself:
"Mankind". Basically, it's made up of two separate words
- "mank" and "ind". What do these words mean?
It's a mystery, and that's why so is mankind.
