We are going to be using Exchange 2013 and IIS ARR as reverse proxy. So far in a test environment I have everything running fine, I even have the ARR boxes clustered. However, I was wondering how would you expose the POP and IMAP services securely
without exposing your mailbox servers?
My first thought would be to have an external IP that NATs to an internal IP which directs to my mailbox server? But I would like to use a reverse porxy/NLB solution to expose POP/IMAP.
Is there anyway I can expose POP/IMAP using the ARR reverse proxy solution?
