More test coverage
New failing tests have been added to 'eml_test.go' to account for a variety of error situations, such as broken FROM, TO, headers, bodies, and unknown or unsupported content types. Improving the robustness of test coverage helps identify potential issues and ensure the resilience and correctness of the code.
