01 Request to Open SMTPS Ports for Email Sending

I have built a system using django and I am attempting to configure email sending through Gmail. However, I have encountered an issue with the SMTPS ports being blocked, preventing me from sending emails.

Here is the current configuration I am using in Django:

EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST = 'smtp.gmail.com'
EMAIL_PORT = 587
EMAIL_USE_TLS = True
EMAIL_USE_SSL = False
EMAIL_HOST_USER = 'belloyusuf1997@gmail.com'
EMAIL_HOST_PASSWORD = 'pkti sjoq opfr jvww'

Despite my best efforts to resolve this on my own, I have been unsuccessful. Could you kindly assist by opening the SMTPS (port 465 or 587) or any other relevant ports required for secure email sending on my linode instance?

Your assistance would be greatly appreciated.

Thank you in advance
