Whitelist for senders that doesn't have reverse DNS

[zimbee]

May I know if there is a workaround to setup whitelist to be able to receive emails from senders that does not have reverse DNS setup for their MX record.

Do you want to disable the PTR record check, or just whitelist certain domains?

Whitelist certain domains.
I still want to enable PTR record check to reduce spammers.

Have a look at this thread:
