Checking email logs

Hello everyone
Does anybody know how can I check outgoing email log? There are some informations in ticket itself that message was send by trigers, but nothing more. Can I check if the email was really send?

Need more information on your system. On a Debian instance running Zammad via apt you can use mailq to see the mail queue.

Oh, my bad, sorry
I’m running Zammad inside docker container(docker-compose) on ubuntu server.
