So I have a company that I've regretfully registered my email address
with and they wont stop sending me messages. I've tried over and over and they
tell me they don't recognize my email address but clearly they're
sending me promotional messages daily. I'm running Postfix 2.7.1 and
would like to know what's the best recommended way to block them?
Should I block them by IP or should I block them via domain name?
Obviously the domain is easily forged in mail headers so I am guessing
an IP range or specific IP would be the best, no?
Below are headers:

Now above in the headers there are to 'Received' sections with what I
think are called 'Client IP's', right? There are two different IP's
and I would like to know if it is recommended I block via IP, which
one and how would I configure Postfix to do this via some kind of
check so it can deny messages from this sender.
Thanks for any assistance!
