I would like users to be able to access their email via OWA and IMAP/POP over the internet. The goal is to have them connect from their home PC's and smart phones to receive this. I would like to know how I get http://mail.domain.com to point to my email server. My website is hosted by a 3rd party provider. My domain name registration was provided by yet another 3rd party provided. My Exchange 2010 server is a local machine. OWA works internally already. I have done nothing to configure IMAP/POP yet... I have a UCC for mail.domain.com already.
