Centralized error definitions in `smtp/auth.go` and updated references in `auth_login.go` and `auth_plain.go`. This improves code maintainability and error consistency across the package.
Refactor error return to include more specific information and add a check for TLS connection state in SCRAM-SHA-X-PLUS authentication flow. This ensures clearer error messages and verifies essential prerequisites for secure authentication.
Introduced new test cases for SCRAM-SHA-1, SCRAM-SHA-256, and their PLUS variants in `smtp_test.go`. Updated the authTest structure to include a `hasNonce` flag and implemented logic to handle nonce validation and success message processing.
Introduce new unit tests to verify SCRAM-SHA-1 and SCRAM-SHA-256 authentication for the SMTP client. These tests cover both successful and failing authentication cases, and include a mock SMTP server to facilitate testing.
Add checks to handle errors when reading client messages. This ensures that an appropriate error message is sent back to the client if reading fails, improving the robustness of the SMTP authentication process.
