EML was designed to store e-mail messages in the form of a plain text file. It is structured with a header and main body, the header consists of the email address of both the sender and recipient, the subject and time and date the email was sent. The main message area of the email is described as the body and can contain hyperlinks and file attachments.
EML files were created to comply with the industry RFC 822 standard which is the standard format for Arpa Internet text messages first conceived in August 1982. EML files contain plain ASCII text for the headers and the main message body and may be exported for the purposes of archiving and storage.
