What is the best way so that efa allows all email going out of our arganization?
By domain or by Email server ip?

i know if we whitelist by domain it would be possible we will be whitelisting spoof emial aswell.

so i know best way would be by the email server private ip. Just would liket some confirmation if this would be the best way to do this.

IP, yes.

From: some ip
To: default
