      I rolled the version of PHPmailer back to 5.2.7, and it seems to have resolved the issue.

      (difficulty: easy, requires administrator access and access to an SMTP server supporting TLS, even if TLS is mis-configured i.e. not ready for production)

      1. Log in as an administrator
      2. Enable SMTP debugging or install https://moodle.org/plugins/local_mailtest
      3. Configure SMTP settings to use the SMTP server above w/o requiring TLS i.e. do not leave smtphosts empty and set smtpsecure to None
      4. Send a test email and look at the debug output. It should tell you about the TLS being available e.g.: 

                                                 250-SIZE 52428800
        		 
                                                 250-8BITMIME
        		 
                                                 250-PIPELINING
        		 
                                                 250-AUTH PLAIN LOGIN
        		 
                                            -->  250-STARTTLS <--
        		 
                                                 250 HELP

        but you should not read about the client asking for TLS i.e. the debug output is missing:

        YYYY-MM-DD hh:mm:ss    CLIENT -> SERVER: STARTTLS

      SMTP connection for forgotten passwords and new user confirmations is no longer working since updating to Moodle 3.0 from 2.0.x. I have tried all the various settings for SMTP authorization type (as well as changing other settings) on the plugins - message outputs - email page, and consistently either get an error message or fail to trigger an email when testing for forgotten passwords, etc.
