Block or Reject incoming mails have sender address with my smtp domain

[muhammadaz]

Hello

We have ESA C190 and our email SMTP domain is "abc.com"

We want to block or drop internet incoming mails which contain our SMTP domain "abc.com" in the sender address

So any internet incoming mail contain my email domain in sender address (spoofing mail) with one of recipient address also from my email domain want to drop or block.

how we can get that configuration in ESA

Thanks
