To see which Dovecot users sign in to retrieve or send emails, you can use the doveadm command to query the logs. Here’s a step-by-step guide:
Step 1. Enable Logging
Ensure that Dovecot is configured to log authentication attempts. You can do this by editing the dovecot.conf file:
log_path = /var/log/dovecot.log
auth_verbose = yes
Step 2. Check the Logs
You can use the grep command to filter the logs for login attempts. For example:
grep 'Login:' /var/log/dovecot.log
Alternatively, you can use the doveadm command to query user information. For example, to check user logins:
doveadm log find
If you want to monitor user log-ins to Dovecot in real-time, you can use the tail command:
tail -f /var/log/dovecot.log | grep 'Login:'
These steps will help you track which users are signing in to retrieve or send emails through Dovecot.
