I’m trying to send an email from my back end that is hosted on an ec2 instance on amazon web services , but the function that runs this part takes a very long time to start the request that it gives me back a timeout error , so i think i need to add the port in the security group but am not aware how to set this up !! here is how my email server settings looks like :

EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST = 'smtp.bizmail.yahoo.com'
EMAIL_USE_TLS = True
EMAIL_PORT = 465
EMAIL_HOST_USER = "my email here"
EMAIL_HOST_PASSWORD = "my password here"
