Does the Exchange server also support direct SMTP or does it require ESMTP?

What is DIRECT SMTP for you ?

Exchange is able to deliver mesage directly to MX record without any relay server.

Exchange 2010 support SMTP Receive connector which you configure for mail flow. The procedure can be found here http://technet.microsoft.com/en-us/library/bb125159(v=exchg.141).aspx

Hope this helps.

No, it doesn't require ESMTP. It will use it if available, but can use regular SMTP as well.
It can also do TLS for secure SMTP traffic.

However if you have something between Exchange and the internet which is scanning SMTP traffic that should be disabled so it doesn't cause problems with email flow. It is also not supported to scan SMTP traffic that is flowing between two Exchange servers in the same Forest.
