Email body signature

[Gianpiero]

Hi all

I have a question about the possibility to create a specific custom signature to block some mail.

I need to block email that contantains:

1- specific email address(it is easy i did it)

2- email with some specific word contained in the email body(for exemple "i wont you")

3- email with specific URL in the body(ex. "www.link.com")

Is it possible?Can you help me to create it?

Thanks a lot

Bye Gianpiero
