What's the issue?
Hi, I've got an issue regarding setting up SMTP properly in Unraid. Maybe somebody got an Idea in how to fix it. The person that has provided the template for unraid didn't setup with SMTP Settings so i've tried to set it up my self.
According to the Docs I've set it up correctly but maybe there are some syntax errors ?
Maybe somebody got it working already should be not so different from normal docker variables settings. But in the doc there are no examples provided. So I was seeking for help here.
Tested it with Gmail and Proton but none seem to work in other case (immich, nextcloud, duplicati) I don't have such issues.
Hello, I have the same problem with my setup (self hosted on Synology NAS with Container-manager). I get the following entries in the log file:

Maybe this helps - I'm also very interested in a solution for the issue.

Hello again,
I could resolve the problem. The cause was improper configuration of SMTP_FROM in the compose.yaml.
So for me the issue is resolved.
