Yesterday only I configure New TMG in our Org. and I am testing all setting, all users can access the internet using TMG, but our Exchange Server is not send and receive emails through TMG
I created the below rules
1-SMTP Rule: Access Type – Allow
Selected Protocol: SMTP, From – Exchange Server to External, Users – All Users.
2-POP3 Rule: Access Type – Allow
Selected Protocol: POP3, From – Exchange Server to External, Users – All Users.
3- DNS Rule: Access Type – Allow
All Outbound Traffic, From – DNS Server & Exchange Server to External
Malware Inspection: Inspect Content Downloaded From web server to client
Could you please tell me I want to create any other rule for exchange server or I have to do any setting in Exchange server to send and receive emails.
