@BRRABill said in How to Require TLS for Outbound SMTP Connections with MDaemon:
I think what he meant was encrypted from the e-mail client (Outlook, Webmail) to the MD server.
That's confusing because it isn't email at that point but is just an internal application API. If it is Outlook, for example, it talks directly with Exchange as a client manipulating stuff on Exchange. If it is OWA, it's Exchange that you are looking at directly (the "email" is still on Exchange.)
