No registration email being sent

[Tio]

I have enabled registrations via:
/var/www/wallabag2/app/config/parameters.yml and fosuser_registration: true

But no registration email is being sent by the server.

This is my parameters.yml file:

# This file is a "template" of what your parameters.yml file should look like
parameters:
    # Uncomment these settings or manually update your parameters.yml
    # to use docker-compose
    #

What email did you register/checked ?

What email did you register/checked ?

I tried a few emails to register. And I never got any confirmation/activation email....

[lapineige]

Just in case, could you try to use the one that comes with your Yunohost account ?

Also : do you receive any email from that server ?

Yes I can login but cannot create new accounts. Others can also login.

Also : do you receive any email from that server ?

Yup we have over 20 services and a few thousand users. The email system works.

Ok. Then I wonder where (which log file) we should check to know what happened to those emails… I'm not knowledgeable enough on this topic 😅

[Tio]

It is ok if we cannot fix it. I will remove that service in a few months time anyway. But could be helpful for others who will use it. Thanks a lot for your help!
