Hello,
I am checking through my Closed Relay settings where I have set the public IP for devices on my network that are allowed to send mail: scanners, printers, monitoring equipment etc.
I notice that I can, and it would be good practice to set the domain from which FROM addresses are allowed.
I would find it convenient if there were also a field with a name or comment for each IP address, so I do not have to remember all the IPs or have to look them up every time.
Eg. 123.123.123.123 | example.com | Main Office scanners
