Email server newbie here. I wanted to get some clarification regarding the trusted hosts. If the listed hosts are already being authenticated when they send/receive mail, they do not need to be placed on the trusted host list correct?
What other situation would I want to place a host in the Trusted Host list?
"2. Remove Trusted Hosts - To ensure only your mail server is able to send mail without being authenticated you need to remove all other entries except for the IP/s your server is bound to. By default this would be the loopback address of 127.0.0.1. You can find this by going to the [Mail, Security, General] tab and here you will see "Trusted IP's & Hosts". In the event you need access to the mail server from other servers on the network then you can place the IP here but it is best to only do this if absolutely necessary and it should always be a single IP and not a range if at all possible."
