Use mailbox.org to send emails from Grafana

2026-07-26 Tags: email grafana mailbox

To allow Grafana to send emails using mailbox.org, you need to:

Create an email app-password from Settings. It only needs SMTP access, so you can disable IMAP.
Configure Grafana using grafana.ini:

[smtp]
enabled=true
host=smtp.mailbox.org:465
user={{SMTP username}}
from_address={{SMTP sender}}
password={{SMTP token}}

{{SMTP username}} is your main email address. {{SMTP token}} is the app-password you created earlier. {{SMTP sender}} can be any email if you have a catch-all address. If you don't have a catch-all address, I believe you can use any of your aliases, but I haven't tested it.
