      @scottalanmiller I've never seen you have to disable security for on-premise Exchange. I would know. 😛

        You do. Obviously, as the issue is lacking TLS.

          That would be an interesting question to bring up among the installations team. I'm going to get some confirmation on this. I'll update back shortly.

            Scott, what do you mean disable security? Surely Office 365 does not require TLS for email?
            Do you mean that the Unitrends can't act as a client of O365 because it can't send via TLS? So the disabling of security in an on premise Exchange setup you mean to say that you have to allow unauthenticated (or at least plain text authentication) for on prem to work?

              As far as Office365 goes:
              http://office.microsoft.com/en-us/outlook-help/settings-for-pop-and-imap-access-HA102908389.aspx

              As far as on-premise Exchange goes, I've never seen or been told you have to disable security of any kind. That's what's confusing me. Why would on-premise work but not Office365? Something just isn't adding up. Working on getting definite answers now.

                @ajstringham I bet that it's because the Unitrends box can't do secure POP, only insecure POP. It all hinges on the fact that Unitrends probably doesn't have the features installed to allow TLS connections.

                  Unitrends has no reason to use POP. It doesn't receive email. Only sends out reports.

                    Which leads to something I've never really understood. When using POP/SMTP clients, SMTP is used to send the email to a local(ish) server. Why can't the client send directly to the receiving side? This implies some sort of difference in client SMTP vs Server SMTP.

                      Office 365 certainly does require TLS. And on premise should always have to. That's been best practice for a long time.

                        Yes. For Unitrends only clear text works.

                          Lots of details are left out. You know that TLS isn't supported. So you know that requiring it has to be disabled. So just put two and two together. You already have the answer, just not spelled out.

                            I don't follow your question. SMTP is SMTP. What is the client and receiving sides in your question?

                              If I'm using Thunderbird as an email client, I have to setup a POP3 and a SMTP server - why do I need an SMTP server setup? Why doesn't Thunderbird try to make and SMTP connection directly with the server that's responsible for the email I'm sending to? i.e. I'm sending one to you at NTG why doesn't Thunderbird do an MX lookup for NTG.CO, connect and send?

                                @Dashrender The SMTP server does that. You're talking about a P2P setup and that's just not possible. SMTP does the sending. No way around that.

                                  Scott, what I'm saying is I've never seen it anywhere in writing or been verbally told that when a client uses on-premise Exchange that they must disable TLS/security. It seems to me if that was the case that Unitrends would automatically be eliminated as an option by anyone in any kind of field with sensitive data (healthcare, finance, government, etc).

                                    And I know for a fact they have clients with sensitive data. I've done the setup. They had on-premise Exchange. They checked to use authentication against the email server.

                                      @ajstringham I understand that it's P2P but the protocol Thunderbird and tons of other clients is using is called SMTP, the same that Exchange, Domino and every other email server use to send messages to each other.

                                        Then again, perhaps that's why it works with on-premise and not hosted. On-premise may be authenticating locally via AD so Kerberos, etc and bypassing authenticating against SMTP directly. Almost a relay workaround?

                                          Sure they use authentication, but it's probably in clear text, not over SSL/TLS.

                                          I'm guessing that on premise Exchange does not require TLS connections from clients by default - you are suppose to enable it because Best Practices tell you to.

                                          I know I use authentication from my copy machines to send email, etc.. but they don't support TLS either, so I know internally my clients don't have to use TLS to connect to Exchange.

                                            @dashrender I guess I just don't understand how Gmail would go to NTG without going through an SMTP server. Are you saying that sending to XX@ntg.co from your Gmail would just send it out and ask for NTG's SMTP info and forward from there?
