Hi I'm trying to send the alerts generated by Prometheus trough the SendGrid SMTP.
Following the SendGrid docs: https://sendgrid.com/docs/API_Reference/SMTP_API/integrating_with_the_smtp_api.html I included the corresponding settings: global: smtp_from: "AlertManager <[email protected]>" smtp_smarthost: smtp.sendgrid.net:587 smtp_require_tls: true smtp_auth_username: apikey smtp_auth_identity: apikey smtp_auth_password: "<MY API KEY>" route: repeat_interval: 1m receiver: default receivers: - name: default email_configs: - to: [email protected] Then with a current alert active in prometheus I'm not receiving any emails. And in the SendGrid dashboard there is no activity either. Also in the logs of the container there is no indication that there is an issue: level=info ts=2020-06-13T20:03:47.844Z caller=main.go:231 msg="Starting Alertmanager" version="(version=0.20.0, branch=HEAD, revision=f74be0400a6243d10bb53812d6fa408ad71ff32d)" level=info ts=2020-06-13T20:03:47.844Z caller=main.go:232 build_context="(go=go1.13.5, user=root@00c3106655f8, date=20191211-14:13:14)" level=info ts=2020-06-13T20:03:47.845Z caller=cluster.go:161 component=cluster msg="setting advertise address explicitly" addr=172.19.0.4 port=9094 level=info ts=2020-06-13T20:03:47.846Z caller=cluster.go:623 component=cluster msg="Waiting for gossip to settle..." interval=2s level=info ts=2020-06-13T20:03:47.872Z caller=coordinator.go:119 component=configuration msg="Loading configuration file" file=/etc/alertmanager/alert-manager.yaml level=info ts=2020-06-13T20:03:47.872Z caller=coordinator.go:131 component=configuration msg="Completed loading of configuration file" file=/etc/alertmanager/alert-manager.yaml level=info ts=2020-06-13T20:03:47.874Z caller=main.go:497 msg=Listening address=:9093 level=info ts=2020-06-13T20:03:49.848Z caller=cluster.go:648 component=cluster msg="gossip not settled" polls=0 before=0 now=1 elapsed=2.001599783s level=info ts=2020-06-13T20:03:57.857Z caller=cluster.go:640 component=cluster msg="gossip settled; proceeding" elapsed=10.010722253s I've tried with the other ports that SendGrid supports but the same result Only when the port is 25 and the smtp_require_tls: is set to false I receive a warning of level=error ts=2020-06-13T20:13:33.862Z caller=dispatch.go:301 component=dispatcher msg="Notify for alerts failed" num_alerts=1 err="*smtp.plainAuth auth: unencrypted connection" Any idea of what I'm missing here?
