| The settings under "E-Mail Notification" are configured to use SMTP Authentication with SSL. Using "Test configuration" leads to an exception: "java.net.SocketException: Connection closed by remote host". The full stack trace is attached. This only happens with the "Test configuration" button. Regular build-failed mails actually work fine. Mail is configured like this (see also jenkins_mail_config.png): SMTP Server: smtp-relay.gmail.com

550-5.7.1 registered in your G Suite SMTP Relay service doesn't match domain of
550-5.7.1 the account this email is being sent from. If you are trying to relay
550-5.7.1 mail from a domain that isn't registered under your G Suite account
550-5.7.1 or has empty envelope-from, you must configure your mail server
550-5.7.1 either to use SMTP AUTH to identify the sending domain or to present
550-5.7.1 one of your domain names in the HELO or EHLO command. For more
