Add tests for MDN address formatting and GetSender logic
Implemented tests for `RequestMDNToFormat`, `RequestMDNAddTo`, and `RequestMDNAddToFormat` methods to ensure proper address handling. Added comprehensive `GetSender` method tests to verify sender retrieval in various scenarios. This enhances coverage and robustness of email message handling functionality.
