Add a boolean flag `authIsActive` to manage redaction of sensitive authentication information in debug logs. When this flag is true, authentication details are replaced with `<auth redacted>`.
Renamed environment variables from TEST_USER and TEST_PASS to TEST_SMTPAUTH_USER and TEST_SMTPAUTH_PASS for clarity and consistency in setting SMTP authentication credentials. This change ensures that the correct credentials are applied during tests.
This commit fixes a regression introduced in v0.5.0. We now set the default SMTPAuthType to NOAUTH in NewClient. Enhanced documentation and added test cases for different SMTP authentication scenarios.
Updated the SetMessageID method to generate a "Message-ID" using a
single randomly generated string combined with the hostname, replacing
the prior complex format that included process ID and multiple random
numbers. This change simplifies the code of the generated IDs.
Revised the character set to include a larger variety of symbols and adjusted the bit size calculations to correspond with the new set size. This ensures more efficient and secure random string generation by effectively utilizing the bitmask.
Removed `randNum` functions and associated tests from `random_119.go`, `random_121.go`, and `random_122.go`. These functions are no longer necessary. Additionally, replaced `TestRandomNum` and `TestRandomNumZero` with benchmarking for `randomStringSecure`.
Updated the TLSPolicy type documentation to improve clarity and consistency. Enhanced the String method with detailed commentary and return value explanation, ensuring it better adheres to the fmt.Stringer interface.
Improved comments for better clarity and detail in SendError-related methods and fields. Updated comments provide more in-depth explanations of functionality, parameters, return values, and usage.
Improved documentation for the Reader struct, its methods, and error handling. Added detailed explanations for `Read`, `Error`, `Reset`, and `empty` functions to better describe their parameters, return values, and behavior.
Expanded randNum function comments to provide detailed behavior and usage across different Go versions. Enhanced the randomStringSecure function doc to explain its cryptographic secure implementation and error handling.
Enhanced the documentation of `Part` struct and its methods to provide clearer explanations, including parameter and return descriptions. This improves code readability and helps developers understand the functionality and usage of each method.
Streamline msgWriter by adding detailed documentation for each method and constant. This includes parameter descriptions, return values, and references to relevant RFCs, improving code readability and maintainability.
Updated the documentation for NumString, XPrioString, and String methods in the Importance type to provide clearer descriptions of their behavior and return values. Enhanced comments for better readability and maintainability of the code.
Updated documentation for the `File` struct and its methods, providing clearer explanations and detailed parameter and return descriptions. Improved readability and consistency of comments across the codebase.
Enhanced comments for String methods on Charset, ContentType, and Encoding types. Detailed the purpose and usage of each method, emphasizing their role in formatted output and logging.
Added detailed doc comments to EML parsing functions, specifying parameters, return values, and providing thorough explanations of functionalities to improve code understandability and maintainability. This helps future developers and users comprehend the usage and behavior of these functions more effectively.
Updated the documentation for the Send method in client_119.go and client_120.go to provide clearer explanations, include detailed descriptions of parameters, and specify return values. Ensured consistency across files by elaborating on error handling and connection checks.
Enhance the SMTP client method documentation by adding detailed explanations of the methods' purposes, parameters, return values, and operational flow. This improves clarity, making it easier for developers to understand the functionality and usage of each method.
Enhanced comments and docstrings for better readability and detail in client.go and b64linebreaker.go. Updated descriptions, added parameter and return details, and included RFC references where applicable for improved documentation quality.
Expanded docstrings for methods in msg.go to provide detailed explanations, parameters, and return values. This improves clarity and helps developers understand usage and behavior more effectively.
Added detailed comments to various methods in `msg.go` for clarity. Each method now includes a declaration, a detailed description, returned values, parameters, and relevant RFC references. This enhances code readability and maintainability.
Enhanced function documentation by adding detailed descriptions of parameters and return values for various methods. This clarifies expected inputs and outputs, improving code readability and maintainability.
