Update: Thanks to to the dev, group emails now work again,

This add-on is broken on TB 128.1 or later. It prevents group emails from being sent. It gives the following error message:

"Whatever Group Email ... is not a valid email address because it is not of the form user@host. You must correct before sending the email"

Disabling this add-on fixes the issue.

I would have posted this on the support site, but I am not signing up for X to be able to do so.

Cette critique concerne une version précédente du module (1.2). 

The homepage of the add-on has changed:

I think it works now, if your list does not have a description, but I missed the changed behaviour if the list does indeed have a description. We will be able to solve this soon.
