Email notifications not working


Email notifications not working however i do the following commands

sudo bench --site localhost enable-scheduler
sudo bench --site localhost clear-cache
sudo supervisorctl restart all

The scheduler services is running however the system didn’t send emails automatically but i can send the email notification manually by click on send now in Email Queue list

Any ideas ?

For changing the time of scheduled interval of email send/receive:
Add/Modify the scheduler_interval: time in sec in sample_site_config.json to change the scheduler time interval.

In case of background jobs being inactive:
Check pause_scheduler inside ./sites/common_site_config.json
if the value is 1 change it to 0
then bench build && bench restart

i made all the changes and still now working automatically however if i click send now it works fine.
is there anything else missing ?
