We have Exch 2007 running on Win 2008. It's a single Exch server supporting internal users and external / Internet email. [We've read the MS guidelines re: edge transport servers], but still dont have one.
We tried to enable TLS but the verb is not available. A MS KB confirms that it's not available on a hub transport server when the Windows SMTP service is installed. We recal the SMTP service being a prereq of the Exchange installation - but can't be certain.
My question is therefore, what are the implications for us and our single Exchange 2007 server (serving internal and Internet email) if we remove the Windows 2008 SMTP role?
