SMTP 587 TLS Encryption not working on Exchange 2013 CAS
Posted on 2014-03-10
I have internet facing CAS servers with Mailbox servers on the backend. My users require connecting to the Exchange from externally via POP SSL or IMAP SSL for inbound and SMTP 587 TLS for Outbound emails.
Everything is working except when I enable TLS or SSL I get an error. If I use none for Encryption and use port 25 or 587 everything works fine.
SSL certificate is in place, a proof of which is POP SSL and IMAP SSL working fine.
Do I need to bind the SSL cert to the receive connector or something?? If so, how?
