clarkwinkelmann Only if I use smtp.163.com server, it works fine....

do you also get that error when Flarum tries to send its emails ? (like the registration email or new post email)

Everything works fine on another server (both servers are using php73 and the same php extension is installed)

      Littlegolden yes but on the same server that has the error, are the other Flarum emails sent without error ?

      Sounds like that server is missing the library for the TLS version used by the mail server, or is missing the certificate to validate the connection. If that's the case ALL emails should fail, not just those from this extension.

        Genji what's your question ? Beta 12 is not released yet.

        EDIT: oh if you were referring to the content of the first post, it was out of date. I have copied the latest version from the README on GitHub. It now shows correctly that it supports beta 11.x.

          The extension can now be installed on beta 12.

          If your forum won't update from beta 11 to beta 12, you can check which extension is the culprit with composer why-not flarum/core v0.1.0-beta.12. If mailing appears in the output, you can run composer require kilowhat/flarum-ext-mailing to first update mailing to its latest version.

            clarkwinkelmann first update mailing to its latest version

            I don't think there's a need for that. The composer update command listed for the beta 12 upgrade allows every package in the root composer.json to be upgraded as well.

                luceos I guessed so. But I prefer writing this just in case. This extension has been a known source of issues for Flarum updates in the past.

                        mekici I have tagged the update 2 hours ago. The Composer command to update Flarum should automatically update this extension, but otherwise you can try running composer require kilowhat/flarum-ext-mailing before starting the Flarum update again.

                        EDIT: my bad, something was wrong with the Packagist hook. Now the update is available on Packagist.

                          Hi @clarkwinkelmann
                          I've submitted a PR for Markdown support. Let me know if I should make this more flexible by making it optional. I just didn't have the time to do this for now.

                          Hello @clarkwinkelmann
                          Thanks for this extension.
                          If I chose smtp mysite.com/admin#/mail , your extension will use smtp or will send from the server where flarum is hosted?

                            teletubbie not that I know of.

                            You can open a new support discussion with details on what you tried and what happens, including any error message.

                              I think this is critical extension for flarum. I should be updated for beta14 and next releases. I hope fof team lead to this extension.
