// ReadEML reads a standard .eml file and returns the parsed email data.
|
|
// EML files are MIME-formatted email messages commonly exported from email clients.

|
|
// Parameters:
|
|
// - filePath: Absolute path to the .eml file
|

|
// PEC emails are Italian certified emails that contain an inner email message
