Plain-Text Email (EML)
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.
EML and MBOX fixtures for email parsers
Standards-compliant RFC 822 messages — plain, multipart text+HTML, and with an attachment — plus an MBOX mailbox, for testing header parsing, MIME decoding, attachment extraction, and mailbox splitting.
Multipart Email — Text + HTML (EML)
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.
Email with Attachment (EML)
A multipart/mixed email with a base64-encoded CSV file attachment — for testing attachment detection, decoding, and extraction from an EML message.
MBOX Mailbox (three-message thread)
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.
