[Bug Fix] Socket Issue in Mailer

[TanmoySG]

Describe the bug While running wIP - both using the flask app and docker container - on my MacBook I faced a Socket Error in Mailer while wIP tried sending a mail.

To Reproduce Steps to reproduce the behavior:

1. Clone the Repo
2. Run It locally - not on Codespaces
3. Try running /register/generate/ , see docs
4. See error

Expected behavior The Flask app should successfully send the mail and return a success message.
