I created a Receive Connector for SMTP (Internal Relays) on our Exchange 2010 Server named SMTP_Relay.
I modified the properites for SMTP_Relay connector under "Permission Groups" to allow :
Legacy Exchange Servers.
I noticed that the "Default HT" Connector has different permissions allowed under "Permission Groups".
Will that make a difference on the changes I made to my new connector SMTP_Relay?
