dear all, I want to ask how to block e-mail sent to one account, let say f...@domain.com. But we can make whitelist too who can sent e-mail to f...@domain.com. I mean like this example: b...@domain.com, a...@example.com, and d...@yahoo.com can send email to f...@domain.com. But other than those three account, email sent to f...@domain.com will be block.
I hope you can understand my question and help me to this problem. thank you
very much
Warm Regards,
Bonar Gultom
