Dear all,

Good Day,

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.

Thanks,
Kumar

Ensure that all your settings are correct by comparing your environment settings to the ones in my article: Exchange 2010 OWA, Autodiscover and POP3/IMAP4 Setting verification through TMG

Hope this helps!!!

The rules you have created Will let you Send emails, (Outbound traffic only) You need to create a Rule to allow traffic from External interface to the Exchange Server.

I recommend the use of the "Exchange publishing Rule Wizard"

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

The best thing to do is publish the Exchange server and use the publishing rules rather than creating access rules. This ensures better performance too.

One major change from ISA 2006 to TMG is that each distinct Exchange protocol must be published seperately.

As for SMTP, what you'll need to configure these two seperate rules:

- SMTP Outbound (access rule)
- SMTP Inbound (mail server publishing rule)

Are you able to connect to TMG from external network on port 25 (smtp)?

Since you are not using Exchange EDGE server role on TMG, you can configure the SMTP server publishing rule. Create these rules:

- Create a Non-Webserver publishing rule
- Name it something like Inbound Access to SMTP Server
- Provide the internal mail server IP address
- In protocol, select SMTP Server
- In network listener, select External
- Finish and Apply
