DKIM / SPF Annotated Email (EML)
An email annotated with DKIM-Signature, Received-SPF, and Authentication-Results headers (all reporting pass) — for testing email-authentication header parsing. The DKIM signature value is a sample placeholder, not real cryptography.

What is a .eml file?
An EML file is a single email message stored in the RFC 822 / MIME format — plain-text headers (From, To, Subject, Date, Message-ID) followed by the body, which may be plain text, HTML, or a multipart structure with alternative bodies and file attachments encoded in base64.
How to use this file
Use an example EML to test email header parsing, MIME decoding, HTML-part handling, attachment extraction, and EML-to-other-format conversion.
Code examples
from email import policy
from email.parser import BytesParser
msg = BytesParser(policy=policy.default).parse(open("dkim-signed.eml", "rb"))
print(msg["subject"], msg["from"])Related files
