Gitea is not sending Notifications


We have a locally hosted Gitea instance and I want to have notification e-mails sent to the users linked to activity. For example, when they are assigned as reviewer for a PR, when there’s activity in a PR they are watching or when they are mentioned.

I have configured Gitea mailer section in configuration and I can send testing e-mails from there without any problem.

Users have e-mail notifications enabled in their profile.

But still they receive nothing and I can’t see any error message in the logs.

Any advice on where to look at?

Thanks in advance!!
