What a .eml file is
EML is a plain-text file in RFC 5322 format: the headers, the body and any attachments encoded inline. Nearly every mail client can open one, which makes it the portable way to archive or forward a message with its original headers intact. Those headers are also why EML is what you send to an IT team investigating a phishing report.
