I’ve also seen quite a few ‘465 problem’ topics too. My email debugging for anything but the obvious is not great though so I have been quoting the troubleshooting guide:

> [@Troubleshoot email on a new Discourse install](https://meta.discourse.org/t/troubleshoot-email-on-a-new-discourse-install/16326/1):
>
> ## Email smtp port selection (Using 465?)
> 
> The ability to be able to [AUTH using ‘telnet’](https://meta.discourse.org/t/troubleshooting-email-on-a-new-discourse-install/16326/114) is extremely important in your first steps of email troubleshooting.

> Port 465 (SMTP over SSL) is largely deprecated in favor of STARTTLS on 25. You may need to try alternate ports such as [port 2525](https://pepipost.com/blog/25-465-587-2525-choose-the-right-smtp-port/) or port 587 (Mail Submission) when things do not seem to work as expected.

Is there something we can add to that to help people?
