Check_user_quota do not send mail [Seafile Pro 7.1.7]

Seafile Server
1

Hello,
When I use the command

> root@/opt/seafile/seafile-server-latest - [] # ./seahub.sh python-env python3 seahub/manage.py check_user_quota

LC_ALL is not set in ENV, set to en_US.UTF-8
Done
Done.

I have the Done Done result but my my users above 90% quota do not receive any mail.
The configuration for sending mail works well because seafile sends invitations and reports every 4 hours.

Ps: I use the command with python3 because with python I have the following error No module named parse while it is well installed

   >  root@/opt/seafile/seafile-server-latest - [] # ./seahub.sh python-env python seahub/manage.py check_user_quota

LC_ALL is not set in ENV, set to en_US.UTF-8
