Notification Email Issue on Master Node

I am having issues with the email system on the master node.

Specifically, the master node is not sending out emails for new account registration, password reset, and others.

I suspect that a port or ports might be blocked, preventing the mail from going out.

Could someone please tell me which port(s) the CryoSPARC uses to send email?

Thank you.

The master node is not expected to automatically send emails for account-related matters. Please see this page for functionality related to user management.
