            Improve the likelihood CiviMails will be delivered. When connecting to some SMTP servers, CiviMail will identify itself in a way that (a) may prevent the server verifying the sender and (b) resembles a spammer. This is a simple fix to improve the way CiviMail identifies itself.

            Description

            This problem relates to the following code in CRM_Utils_Mail::createMailer() ...

                  $params['localhost'] = CRM_Utils_Array::value('SERVER_NAME', $_SERVER, 'localhost');

             When being executed by the CLI, 'SERVER_NAME' is unset so the mailer will identify itself as "localhost" in SMTP EHLO or HELO commands.

            In our experience using G Suite for Non-profits, Google rejects these emails. The problem rights itself when we replace "localhost" with our host name.

            I'll supply a patch that gets the host from CIVICRM_UF_BASEURL if SERVER_NAME is unset.
