It just hangs. Nothing more is logged Thread-1. So I started digging around the the python source, starting from refresh_local_conf_file. I ended up in ./broker/notifications.py, in send_email. I added some logging: def send_email(cfg, email_body): """Send email.""" logger =3D logging.getLogger("%s.Notifications" % __name__) try: logger.debug("#### setting up smtp 1") server =3D smtplib.SMTP(cfg["smtp-server"], port=3Dcfg["smtp-port"]) logger.debug("#### setting up smtp 2") ... Now the final messages are: Thread-1::DEBUG::2016-07-21 21:35:05,280::config::278:: ovirt_hosted_engine_ha.broker.notifications.Notifications.config:: (refresh_local_conf_file) local conf file was correctly written Thread-1::DEBUG::2016-07-21 21:35:05,282::notifications::27:: ovirt_hosted_engine_ha.broker.notifications.Notifications:: (send_email) #### setting up smtp 1 So the culprit is: server =3D smtplib.SMTP(cfg["smtp-server"], port=3Dcfg["smtp-port"]) Note that this does actually send the email - 2 minutes later. So I tried: $ telnet localhost 25 Trying ::1... which hung, and a little bell went off in my brain... After changing /etc/hosts from: 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdoma= in4 ::1 localhost localhost.localdomain localhost6 localhost6.localdoma= in6 to 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdoma= in4 ::1 localhost6 localhost6.localdomain6 localhost resolves to 127.0.0.1, the delay is gone, and everything is fine. I don't want to update /etc/hosts on each host. Is there somewhere I can edit the broker config for mail? Robert --=20 Senior Software Engineer @ Parsons --Sig_/d5HsVgY=1qVXe_5rLqOUAM.
