Hi, I use OSS Grafana 9.5.2 with native Alertmanager.
I have contact point with email integration. If one of email addresses is failed, I have alert messages on all email addresses in the contact point every minute.
Logs - notify retry canceled due to unrecoverable error after 1 attempts: failed to send notification to email addresses: gomail: could not send email 1: 550 unknown user"
If I send message to this broken email address, I get 550 error too.
What I need to do with configurarion, for disable retries sending alert emails, if address in contact point failed?
