Lock Domain to IP Address
Question asked by Kevin Russell - November 7, 2017 at 4:04 AM
Can someone point me to the KB Article that shows how to lock a SmarterMail 16.x  Domain to receive mail from a series of IP addresses and excludes all others?

Hi, Kevin
While you can lock Outbound SMTP per domain to specific IPs on your server, there's not a feature within SmarterMail itself that will block incoming connections from all but a range of IPs. Ideally this would be done at the head of your network using your firewall.
