chore: update action mailer configuration

- Set host option for action mailer to use ENV variable
- Added SSL, open timeout, and read timeout settings
- Ensure authentication method is a string

These changes streamline the action mailer configuration by introducing
additional parameters for a more secure and efficient operation,
improving overall email delivery reliability.
