I have a person with a gmail account spamming me. Daily.
What i want to know if is exim can reject emails coming from address like [email protected]?

So far all i've found is blocking emails sent from exim server or to a specific exim account.
This isn't what i need.

I need to block an external email address from sending emails to me.

Thanks!
