Isn't there a way to bounce email to your site back to the sender?

I want to disable all ability to receive email to my site.

I read somewhere there is a code or something you can use to bounce any email being sent to your website back to the sender unread. Anyone know what it is and how to apply it?

If your zone files don't have an MX record pointing to your domain IP address, no mail will go through.

I host several sites for which I don't provide email. I set the "A" records to the IP address of the server, but don't set an MX record.

No mail gets through to those domains.

I went in and made the MX entry blank. Thank you for your reply.

Good for me too.

Thanks ;)
