This PR updates the `[mailer]` configuration snippet for Gmail: - The `HELO_HOSTNAME` isn't required. - The `USER` must not include the @gmail domain. - `HOST` needs to be supplied, and the SMTP port number needs to be appended to the URL. I also added a note about the requirement to use App passwords instead of your Google account password directly. Co-authored-by: delvh <dev.lh@web.de>
