How to enable TLS on incoming emails in Exchange 2003
Posted on 2011-03-09
I have been reading dozens of posts and KB articles but i'm stuck.
My customer has been told they need to be able to receive secure emaisl via TLS.
Okay, I have ordered and received the ssl cert for mail.domain.com.
I understand in Exchange 2003 TLS is either on or off. they need to receive normal unsecure email and new secure email so I think that means I need two SMTP Virtual servers. One with TLS and one without.
I think I am supposed to add a second IP address to the NIC and use that IP address in a new TLS SMTP Virtual server - Is that correct?
If each SMTP VS has a different IP then how do I NAT the incomming emails (port 25) to the two different SMTP ?
Am I completely off the mark???
