Refactor variable names in SMTP client code

Browse source 
Improved variable names in the SMTP client code to make them more expressive and descriptive. Also corrected several code comments to enhance clarity. These changes are intended to increase code readability and maintainability and have been implemented throughout the client_119.go and client.go files for consistency in naming conventions.
