Block Incoming Email Sent To A Specific Address

Block Incoming Email Sent To A Specific Address

I have an email that receives a LOT of spam that goes to my catch-all email address. This is an email address that used to exist with the company, but is no longer there. I know I could make an account for this email and turn off incoming traffic. But I would prefer not to make an account just for this purpose. I've read all about policies and blacklisting, but I can't find a way to stop incoming mail that is specifically routed to this email address. Is there a way for my to do this? Right now, I have a filter setup in the catch-all email account to send these emails to trash. However, ones that get routed to spam are still in the spam box for review. I would like any emails to this address to be bounced back to the sender.

Thank you.
