Do your clients use the TMG as their default gateway? If they do, then you just need to create an outbound permit rule, and then ensure that any other firewall also permits the outbound traffic. If the TMG is not the default gateway, the easiest solution may be for you to use the TMG client. From what you are describing, it sounds like the TMG is not the default gateway. When you configure your browser to use the TMG as a proxy, web traffic is directed to the TMG. Email client traffic is not unless you use the TMG client. However, depending upon which email client you use, you may be able to configure it to use the TMG as a socks proxy. I think Thunderbird can use a proxy, but I don’t have it installed and don’t have time to do that for you.

Hi Ed,

Thank you for your prompt response – One thing I have to ask and will be grateful for a step by step (a quick summary here in the comments would do) is the following :

My Email Box is in a remote data centre (it is not exchange server),it supports only pop, imap and smtp and no SSL, we will upgrade to a new one later this year (hopefully).

I tried uninstalling the tmg client on my 7 and xp machine as a test and tried to use outlook 2007, 2010, thunderbird, none of which connected – however I was able to browse the internet when I had tmg defined as a webproxy.

I even tried to publish a rule allowing smtp, pop, imap to and from my email server but none of which worked.

Will be most grateful if you could provide a step by step so that I can set that up and get rid of TMG Client ?

——————————-
Also, If we had Exchange either remote or on-premise – would TMG client be mandatory then ?

Thanks so much !!

Yes, but don’t be that guy. Not using the TMG client is fine…I don’t use it either. I try to avoid anything that requires me to install additional software on clients.
Accessing email using unencrypted protocols is bad. ALWAYS use the SSL or TLS versions to protect data, but more importantly, to protect user credentials!

Hi Retrohack,

I have a TMG EE server on my LAN, I do not want to install TMG Client on my client computers rather use the web-proxy configuration in IE8 and IE9, but :

We have a Mail server in a data-centre, which we all connect to send and receive email via OUTLOOK.

Is this possible to use outlook 2007 and 2010 with POP / IMAP and SMTP (No SSL / TLS) without installing TMG client ?

Will be grateful
