That's not enough information to help. If you're not prepared to share the alertmanager.yml configuration file, then at least you need to show the logs from alertmanager at the time it tries to send the mail (e.g. "journalctl -eu alertmanager" if you're running it under systemd). You should also check mail logs on the SMTP relay that you've pointed alertmanager at.
Basically, the chain of events is: 1. alertmanager decides to send a notification email 2. alertmanager sends the email to the SMTP relay 3. the SMTP relay forwards the mail to the final destination Hence you need to check each link in this chain: - is alertmanager actually trying to send an email? (alertmanager logs will show you this) - If it does, does the SMTP server accept it or reject it? (alertmanager logs will show you this) - if the SMTP relay accepts the mail, then why is it not delivering it? (smtp relay logs will show you this) On Tuesday, 25 February 2025 at 12:16:28 UTC Chinelo Ufondu wrote: > Hello all > > I currently have an issue with receiving a test mail from alertmanager > after configuring the alertmanager.yml file and starting alertmanager.
