Add error handling for writing EML string to temp file

Browse source 
Added conditional statements to handle potential failures when writing the EML string to the temporary files during testing. These updates ensure test failures due to write errors are accurately reflected in test results. Also, a minor fix is implemented on file permission in the os.WriteFile function.
