Thanks, I tried that after doing what I described and still the same deal where it works for a while and throws the 530.5.7.1 client was not authenticated.
I also found that if I disable/enable the new receive connector via the management console it will again handle mail for over an hour. Then I tried deleting the new connector and creating a new connector via the management shell from another MS article using a different name for the connector: PS] C:\>New-ReceiveConnector -Name "svr4 relay" -Usage Custom -AuthMechanism ExternalAuthoritative -PermissionGroups ExchangeServers -Bindings 192.168.5.100 :587 -RemoteIpRanges 192.168.5.111 That will handle mail for over an hour and then 530.5.7.1 client was not authenticated. I can disable/enable the connector as I described and it will work for over an hour.
