Hello softley,

Do you have a public IP address? if so, is it static? and do you have more than one Public IP address? answer those questions and we can give you the correct answer :)

Regards,

Type Nslookup - hit enter once.
Type set q=mx - hit enter once.
Type domain name (The domain name which is actually your email address - abc@microsoft.com - so domain name in this case is microsoft.com)

Ideally, you should inform your ISP as soon as you setup Exchange.

Normaly setup of exchange are for emails coming in

Internet => Firewall => SMTP Gateway => Front-End Server => Back-End Server

The Front-End Server can be replaced by a normal BackEnd Server.

So, in this case your MX record will be hitting your public IP of your firewall - firewall when it gets the message on port 25 (should have a rule to) forward it to its internal ip address, which in turn forwards it to a SMTP Gateway (could be any box with AV + Anti Spam applications on it) - this forwards it to FE Server.

Once, FE server gets the message it wil re-direct the message to BE server (thats how Exchange works nothing new in it)

Now, some people cannot have such a setup so what they setup mail flow as

Internet => Firewall => Exchange Server.

Although there is nothng wrong - but then the Exchange server needs to have a strong AV and Anti-Spam agents installed on it since Firewall wont check all that.

Hope i have cleared doubts rather than increasing them..hehe

Ideally, every one needs to update their ISP about hosting their MX record.
