Not able to send the email notification

[bharat4212]

i am trying to send the email notification but its not working.

i am using docker compose to run the defectdojo, configured the below variables but its not working

  DD_EMAIL_HOST: smtp.xxx.test.com
  DD_EMAIL_PORT: 587
  DD_EMAIL_USE_TLS: "True"
  DD_EMAIL_USE_SSL: "False"
  DD_DEFAULT_FROM_EMAIL: noreply_defectdojo@test.com
  DD_ENABLE_EMAIL_NOTIFICATIONS: "True

i can see the env variable in django-defectdojo-uwsgi-1 container as well.
but if i am trying to send email from vm on which defectdojo is running its working. what could be the reason.

Your support is appreciated as always.
