SMTP Configuration for GMAIL and AWS SES on Open edX Lilac Master

The scenario is: I have a .edu. domain that is using Google Workspace for managing email accounts. The Open edX Lilac Master Release is configured on a .com domain and I want to configure the Open edX emails from .edu. domain by using the AWS SES. The AWS SES account is in production (Not a sandbox). The .edu. email address is verified on AWS SES. On Open edX Accounts Creation or Password Resets, the email are going to SPAM in accounts created from @hotmail.com while DELIVERY FAILURES on @gmail.com accounts.

My following settings are working fine with Gmail SMTP account while partially working with AWS SES for @hotmail.com, but not for @gmail.com:

DEFAULT_FEEDBACK_EMAIL: example@example.com
EMAIL_BACKEND: django.core.mail.backends.smtp.EmailBackend

// FOR AWS SES
EMAIL_HOST: email-smtp.us-east-1.amazonaws.com

// FOR GMAIL
EMAIL_HOST: smtp.gmail.com

EMAIL_HOST_PASSWORD: **************
EMAIL_HOST_USER: example@example.com

EMAIL_PORT: 587
EMAIL_USE_TLS: true

The SSL Certificate is from Let’s Encrypt.

Is there something else that needs to do for configuring AWS SES?
