Hi Chris,
 
Is this server receiving incoming connections from SMTP servers outside
the firewall? If not, then you don't need to worry about this unless
your internal network is compromised.

        The problem is, I need to allow relay internally. I have various
custom apps that the users need to email a client upon completion of a
workorder. They each do over 500 a day and automation is the only way to
do this effectively. So, if I shut off the checkbox in question, will
the internal IPs still be able to relay?

        Hi Chris,

         

        Yes. If you don't allow relay, then the server will not relay.
You can also do other things like prevent the machine from resolving
Internet host names (just for fun).

         

        HTH,
