      I told you that oyu gave the corect answer on an incorrectly worded question.

      And how was it incorrectly worded?

          This is very different from what you asked. You asked about getting email working from the OS, and the OS does it with postfix and the standard mail command that you were trying to use depends on an MTA. Other applications may have their own SMTP individually. But that is a question about an application sending email, not about Linux or the OS sending it. Totally different concepts.

          It is, but like everything here at ML the original question got critiqued and then spun into a new thread.

          But it is a totally new topic. You should ask that in a new thread. As it is not directly related to the topics discussed.

          THink of it this way....

          Windows can't send email as Windows. But Thunderbird on Windows can send SMTP itself. Just because an app brings a capability doesn't mean that the OS has that capability.

            Did you want to know about Fedora sending email or dnf-automatic sending email?

            Fedora is what was asked about.

              OK, so let's take this a step back.

              Bob is an IT admin. He hosts his mail on Office365.

              He wants to use dnf-automatic to send mail.

              How does he do this?

                My root issue, I guess, if that I cannot get dnf-automatic to send e-mail to any public e-mail servers. Not Office365, for example.

                This is because Office365, Google, etc email does not accept and send out emails for just any random email server.

                They require authentication.

                This is why you need to use, in the case of dnf-automatic, an SMTP server that is set up and authenticated with Office365. That way when dnf-automatic sends out an email as [email protected], it goes to your SMTP server to authenticate, then sends via whatever account info the SMTP server is authenticating by... whether it's a global "[email protected]" address or whatever.

                  This is what I am contending. That just entering a SMTP server in dnf-automatic will not get the job done. Unless you own it and can control it. Or use some sort of authentication.

                  However, postfix does seem to work to Office365, and GMail. No questions asked.

                    That makes no sense and is obviously wrong. All MTAs work with all systems, always. SMTP doesn't have versions or compatibility problems. Obviously you've taken a misconception and extrapolated something totally untrue from it. Something that is disproved every day as postfix is one of the most broadly used email platforms (ever heard of Zimbra... nearly all email systems build off of postfix) and all of us have this work flawlessly every day.

                        Gmail for example won't let you send out an email using [email protected] unless you authenticate first. Otherwise, I could simply type in a "from address" of [email protected] and send emails from you to whoever i want. So this is understood.

                        DNF automatic doesn't give the option to authenticate.

                        Does postfix give you authentication options?

                          Actually they do. Both O365 and GMail accept without any of that stuff. Specifically, both of those we test with this all the time. Many email systems do require that, but not those.

                          I've tested in the last 30 minutes from a new install, in fact.

                            Still makes no sense. He wants dnf-automatic to send email TO WHERE?

                              Looks like it does. Just set up postfix to use your email and password to send mail out.

                                So you're saying that Gmail will let me send an email as [email protected] or whatever yoru gmail is (if you have one) without me having to authenticate? I can guarantee you it will not. This must mean you took what I said the wrong way.

                                    Wtf... how can Gmail let you send emails as someone without knowing their credentials?

                                    That means I can start sending emails as [email protected] or w/e you email is, without knowing yoru passwor.d

                                            My root issue, I guess, if that I cannot get dnf-automatic to send e-mail to any public e-mail servers. Not Office365, for example.

                                            This is because Office365, Google, etc email does not accept and send out emails for just any random email server.

                                            They require authentication.

                                            This is why you need to use, in the case of dnf-automatic, an SMTP server that is set up and authenticated with Office365. That way when dnf-automatic sends out an email as [email protected], it goes to your SMTP server to authenticate, then sends via whatever account info the SMTP server is authenticating by... whether it's a global "[email protected]" address or whatever.

                                            Actually they do. Both O365 and GMail accept without any of that stuff. Specifically, both of those we test with this all the time. Many email systems do require that, but not those.

                                            I've tested in the last 30 minutes from a new install, in fact.

                                            So you're saying that Gmail will let me send an email as [email protected] or whatever yoru gmail is (if you have one) without me having to authenticate? I can guarantee you it will not. This must mean you took what I said the wrong way.

                                            That's an unrelated thing that you are attempting. I said that you can send email TO Gmail, not pretend to BE Gmail!

                                            Yeah that's not what I"m talking about then.

                                            Yeah you can send email to any email. But I'm talking about sending as.
