[MM3-users] How to get Mailman core to provide more debug info in a running environment

Docker-mailman 0.1.1

I am using Mailman 3.1 in production and I am trying to debug a problem[1] so I tried to setting Mailman to provide more debug info in the smtp.log file[2]. I might have been doing it wrong, but in the mailman-extra.cfg I set

[logging.smtp-failure] path: smtp.log

and restarted Mailman, which stopped incoming mails until removing the added section. What is the correct way to get Mailman to provide more debug info in the smtp.log
