arquivos EML vs EMLX

<!---- What are EML and EMLX files? ------------------------------------>

EMLX files are sometimes called Apple Mail Email files because 
they're typically created with Apple's Mail program for macOS. 
These are plain text files that store just a single email message.

EML files (without the "X") are often called E-Mail Message files
and are generally used by Microsoft Outlook and other email clients. 
The entire message (attachments, text, etc.) is saved.
