EML File Format

Microsoft Outlook Express mail message (MIME RFC 822)

EML file format icon

EML is a file extension for an e-mail message saved to a file in the MIME RFC 822 standard format by Microsoft Outlook Express as well as some other email programs.  

EML files can contain plain ASCII text for the headers and the main message body as well as hyperlinks and attachments. 

EML files may be exported for the purposes of archiving and storage or scanning for malware.  The Nimda virus is known to create EML files.  When EML files are found as an included attachment it is good practice to scan with anti virus before opening.

MIME type: message/rfc822
