Built-in Metrics

Bleemeo monitors the Exim4 mail transfer agent through automatic service detection, SMTP health checks, and mail queue metrics.

Auto-Detection

Glouton automatically detects Exim instances listening on port 25.

To enable metrics gathering, ensure Glouton can run the mailq command. This usually means adding the following to your Exim configuration (e.g. /etc/exim4/conf.d/main/99_local):

queue_list_requires_admin=false

Then refresh the configuration:

update-exim4.conf.template --run
update-exim4.conf

If the auto-detected parameters are incorrect, you can override them manually.
