Re: How can I create an email rule to block a specific SMTP server

I agree with you Graham_A. The filters can only be looking at the header because that is what contains the all information about an email apart from its contents! The question I want to know is what rule config would allow me to filter based on the Received-from SMTP chain in the header? I know that the chain in the header starts at the bottom of the list and works up as each SMTP server forwards the email from the previous one but know which filter actually looks at any of these Received-from chains is the question.
