Hi all!
I've been using the smtp-relay.gmail.com smarthost without authentictaion but it stopped working. But I can send mails via local postfix using the gmail relay host, so the issue seems to be on the Alertmanager side. *Alertmanger log file:* receiver=email integration=email[0] msg="Notify attempt failed, will retry later" attempts=1 err="send EHLO command: EOF" msg="Notify for alerts failed" num_alerts=1 err="email/email[0]: notify retry canceled after 6 attempts: send EHLO command: EOF" *My Alertmanager config:* global: smtp_smarthost: smtp-relay.gmail.com:587 smtp_from: 'Alertmanager <alertmanager@XXX>' smtp_require_tls: true route: group_by: ['alertname'] group_wait: 10s group_interval: 10s repeat_interval: 24h receiver: 'email' receivers: - name: 'email' email_configs: - to: 'XXX' send_resolved: true Thanks in advance! -- You received this message because you are subscribed to the Google Groups "Prometheus Users" group.
