Just to check: In settings, is assign items to users set to yes and the list view type set to group?
The plugin uses WordPress’s built in mail system. Perhaps a plugin like https://ww.wp.xz.cn/plugins/wp-mail-smtp/ would help.

Thanks for your very fast reply!
Yes, both options are set like that. The mailserver itself is operating correctly. I also think that the mails did work couple of months ago…
Sending mails over the PHP mail()-function does work correctly (over CLI and over the webserver). Doesn’t WordPress use that function too? That’s a bit strange.
I will do some further investigation.

Okay, sorry for disturbing you: It seems that this is an issue of WordPress itself. Sadly the plugin does not help in any way – WordPress is reporting an error, that “no recipient was entered”. Whyever…
I mark this case as resolved as this seems to be a WordPress-related issue. Thank you for your help!

I finally solved this very strange behaviour. Even if it has nothing to do with this plugin, I want to share my solution: It seems that a PHP version has some issues with the PHPMailer library, which WordPress does use.
After updating PHP 5.6.9-1~dotdeb+7.1 to 5.6.10-1~dotdeb+7.3 everything does work fine again like couple of weeks ago – even the automated sending of mails of the great todo-plugin! 🙂
