Unable to send email from the qBittorrent app

Here is a issue that has been bugging me across several versions of qBittorrent. It worked in the past, but stopped working a few versions ago. Not sure why. I am currently running App Version: 5.2.0 Version: 1.4.7

I’m using Brevo as my SMTP service after Google stopped allowing SMTP emails. All of my other apps on TrueNAS, TrueNAS notifications, and email notifications for TrueImage and CyberPower are working fine. I have confirmed that the email server, username, password, and email addresses are configured correctly. SSL is enabled. However, when I send a test mail, it appears not to go out. When I check the status dashboard on Brevo, the email isn’t even being received, so I’m suspecting that it’s trapped within the Docker container.

This is my network configuration:

qBittorrent works fine, and the email notification is a “nice to have” feature, not a “need to have”, so I’ve been disabling it. When I send a test email and monitor the logs, I’m not seeing any log entries.

According to the Dockerfile for the app, a SMTP MTA doesn’t appear to be bundled in the app anymore.

Per the qBittorrent version history, the last version that had SMTP support was 4.5.0.

Right…. it was a nice-to-have feature, but not a showstopper.
