A bounce / non-delivery report (NDR), a multipart/report message with a human-readable notice, a message/delivery-status part, and the original headers, for testing bounce parsing and delivery-status extraction.
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.
A multipart/mixed email with a base64-encoded CSV file attachment, for testing attachment detection, decoding, and extraction from an EML message.
SAMPLE delivery/DSN-related .eml (bounce-mailbox-full) for mailbox parsers.
SAMPLE delivery/DSN-related .eml (calendar-invite-note) for mailbox parsers.
SAMPLE delivery/DSN-related .eml (dsn-delayed-plain) for mailbox parsers.
SAMPLE delivery/DSN-related .eml (dsn-failed-plain) for mailbox parsers.
SAMPLE delivery/DSN-related .eml (out-of-office) for mailbox parsers.
SAMPLE delivery/DSN-related .eml (receipt-mdn) for mailbox parsers.
SAMPLE .eml focusing on auto submitted header behaviour.
SAMPLE .eml focusing on content language header behaviour.
SAMPLE .eml focusing on dkim signature shape header behaviour.
SAMPLE .eml focusing on list unsubscribe header behaviour.
SAMPLE .eml focusing on priority urgent header behaviour.
SAMPLE .eml focusing on reply to different header behaviour.
SAMPLE .eml focusing on return path header behaviour.
SAMPLE .eml focusing on thread topic header behaviour.
The failing twin of the all-pass fixture, headers otherwise identical: SPF fail, DKIM fail with a quoted reason property, DMARC fail under p=REJECT. The quoted reason string contains a semicolon-free phrase specifically to test method-splitting.
The fully authenticated baseline: SPF pass, DKIM pass, DMARC pass with aligned domains, under a p=REJECT policy. The DKIM signature is a visible SAMPLE placeholder, so the header parses and reports pass but will never verify cryptographically.
A base64 text/plain message in utf-8 carrying the identical body to the quoted-printable twin beside it. Base64 is opaque to whitespace and line-start characters, so it is the reference side of the pair when a QP decoder is suspect.
