Add null check to prevent empty file handle error in msg_test.go
Implemented a null check to ensure the 'fi' file handle is not empty. With the absence of this check, the test was continuing even when 'fi' was empty, leading to null pointer exceptions further down in the code.

Fix potential null pointer exceptions in msg_test.go
Added robustness and improved error handling in msg_test.go by adding null checks before calling values from the genHeader map in RequestMDNTo and related functions. This enhancement was necessary to avoid the operations on non-existing keys and potential null pointer exceptions.

Improve error handling in msg.go
Added additional checks when calling values from the genHeader map in msg.go file. This is to prevent trying to operate on non-existing keys, hence avoiding possible null pointer exceptions. The checks ensure the key HeaderMessageID exists in the genHeader map before attempting to operate on it. This is essential for functions like RequestMDNTo, RequestMDNToFormat, and RequestMDNAddToFormat, thereby improving the robustness of the code.

Protect against key not found in genHeader map in msg.go
Added checks to ensure the key HeaderMessageID exists in the genHeader map before attempting to operate on it in msg.go. This will prevent possible null pointer exceptions when trying to assign the key a value or append it to the mids slice.

Add checks for nil or empty Subject headers
Added condition checks in `msg_test.go` for nil or empty Subject headers in the assigned functions. If the Subject is found to be nil or its length is less than 1, an empty string is now appended to prevent issues arising from null pointers or non-existent Subject headers in email messages.

Fix null pointer exception in Is function
Updated the Is function in senderror.go to handle null values for SendError. This was done by adding a nil-check for surfaced pointer errors in the errors.As call. This prevents the function from attempting to derive values from a null pointer and consequently prevents null pointer exceptions from being thrown.

Handle nil buffer in Reader and update tests
Updated the Reader struct in reader.go to properly handle nil buffers. This prevents potential errors from nil pointer dereference. Also added the fmt package for debugging purposes. Correspondingly, additional tests in reader_test.go were also added to cover these edge cases and ensure the Reader struct correctly handles them.

Update range loop to improve msg function readability
Converted the range loop in the GetAddrHeaderString function in msg.go to use value semantics rather than index notation. This improves code clarity by not unnecessarily referring to m.addrHeader[h] in the loop and instead referencing the value directly (using variable mh), making it easier to understand and maintain.

"Improve error checking in SMTP client creation"
A change was made in the SMTP client creation process to add more robust error handling. The new logic checks if the client is null after being created and, if true, returns an error. This update can help prevent potential null pointer exceptions in runtime, ultimately leading to more stable application.

Handle nil pointer in IsTemp method in senderror.go
Added a nil check in the IsTemp method in senderror.go to prevent runtime errors when method is called on a nil object.

Protect against empty address list, refactor error handling
Added a condition to prevent assignment of an empty address list to the 'HeaderFrom' scenario. This eliminates potential runtime errors when trying to access an nonexistent element of a slice.
Adjusted error handling in the sendmail execution part by reusing the 'err' variable, promoting cleaner, more readable code.

Add time import and tests for invalid date in email
Added `time` import in the eml_test.go and added two new test use-cases: `exampleMailPlainNoEncInvalidDate` and `exampleMailPlainNoEncNoDate`. The `exampleMailPlainNoEncInvalidDate` is used to check if the parser can correctly handle email with invalid date. Meanwhile, `exampleMailPlainNoEncNoDate` checks if the parser can correctly add the current date to an email that didn't specify a date. This will improve the parser's resilience and flexibility in handling various email scenarios.

Add EML parsing from string to tests
A new test `TestEMLToMsgFromString` was added to "eml_test.go". This test asserts the proper functionality of `EMLToMsgFromString` method that allows us to parse EMLs directly from a string input. This test is a necessary part of ensuring the functionality and reliability of our EML parsing process.

Refactor EML file parsing and header extraction
We can no parse simple mails (multipart is not working yet). The existing implementation was made more efficient by refactoring the EML file parsing and header extraction mechanism. Added 'strings' and 'bytes' packages to facilitate these changes. Previously, headers and body were parsed separately which was unnecessarily complex and increased the chance of errors. Now, with the new function 'readEML' and the helper function 'parseEMLBodyParts', we are able to parse headers and body together which not only simplifies the code but also increases its reliability. Specifically, 'bytes.Buffer' now helps us capture body while parsing, which removes need for separate handling. Additionally, certain headers like 'charset' and body types are also accounted for in the new implementation, enhancing the completeness of information extracted from EML files.

Extract and set charset from email content type
The diff modifies how the email library handles the extraction of the mime media type from an email header. It uses the mime.ParseMediaType function to parse the content type header. The function gives back the media type as a string and a mapping of different associated parameters. This mapping was previously just printed, but now the charset parameter is also used for setting the charset of the email if it exists.

Add EML parsing functionality to mail package
Added two new functions `EMLToMsg` and `readEML` to the `mail` package. `EMLToMsg` function opens and parses a .eml file and returns a pre-filled Msg pointer. `readEML` opens an EML file and uses net/mail to parse the header and body. These changes are made to provide support for EML file parsing, which is a common requirement in many email-based applications.

#142 Add structured JSON logger and associated tests
This commit introduces a new type 'JSONlog' that satisfies the Logger interface for structured JSON logging. This includes new methods 'Debugf', 'Infof', 'Warnf' and 'Errorf' to log messages at different levels and an associated test 'jsonlog_test.go' to ensure correct functionality. This enhances the logging functionality by providing clarity in logs and eases debugging process.

Refactor log level and direction function to separate file
Moved Level constants and directionPrefix() function from log/stdlog.go to log/log.go. This change improves the organization of the code by grouping log level constants and related functions in the same file. Furthermore, this removes redundancy and ensures consistency of log level across different files.

Remove unnecessary .idea XML configuration files
The deleted .idea XML configuration files (markdown.xml, modules.xml, Project_Default.xml) were not required for the functioning of the project. Removing these files helps in reducing clutter and simplifying the project structure. Also, these files can often contain user-specific settings or paths, and may cause conflicts when working in a team.
