A forwarded message carrying a two-instance ARC chain (Seal, Message-Signature and Authentication-Results at i=1 and i=2), where DKIM broke in transit but ARC records that it passed upstream. Every seal is a visible SAMPLE placeholder, not real cryptography.
An email whose Subject uses RFC 2047 UTF-8 encoded-words (café / crème), for header decoding tests.
An attachment whose filename uses RFC 2231 UTF-8 encoding (résumé), for MIME filename decoders.
An HTML newsletter email (multipart/alternative) with a table-based responsive layout and a List-Unsubscribe header, for testing HTML-email rendering, sanitising, and marketing-email parsing.
Standalone SAMPLE iCalendar CANCEL for calendar parsers without MIME wrapping.
Standalone SAMPLE iCalendar REQUEST for calendar parsers without MIME wrapping.
An mbox mailbox concatenating a short three-message email thread with the classic 'From ' separator lines and >From body escaping, for testing mailbox splitting and thread reconstruction.
A larger mbox mailbox with a six-message back-and-forth thread, for testing mailbox splitting, thread reconstruction, and pagination over more than a couple of messages.
One mailbox whose four messages each use a different charset and alternate between quoted-printable and base64, with RFC 2047 subjects to match. The file itself is LF-stored while the encoded payloads decode to CRLF text: the split every importer has to handle.
Three messages in one mailbox: an original whose body contains both a bare "From " line and an already-escaped ">From " line, the reply that threads to it, and the multipart/report bounce that reply triggered. mboxrd escaping is what makes the round trip lossless.
A meeting-invitation email carrying an iCalendar (.ics) VEVENT with METHOD=REQUEST, for testing calendar-invite detection, ICS extraction, and RSVP handling.
A multipart/alternative email carrying both a plain-text and an HTML body, for testing MIME part selection, HTML-part handling and sanitising, and multipart parsing.
An order-confirmation / receipt email (multipart/alternative) with an itemised order table in both text and HTML: a transactional-email fixture for testing parsing and data extraction.
A standards-compliant plain-text email message (.eml) with full headers: the simplest valid RFC 822 message for testing email header parsing and EML import.
