Emaildata

Emaildata is the data associated with electronic mail messages and related systems. It encompasses the information carried inside messages (headers, body, attachments) as well as metadata generated by mail servers and clients during transmission and storage. It is used for communication, archiving, and analysis.

Key components include headers (From, To, Subject, Date, Message-ID), the message body, embedded or attached files, and routing logs such as delivery status notifications and trace information. Metadata can include timestamps, server names, IP addresses, and client identifiers.

Standards and formats: Emaildata is structured by protocols and standards such as RFC 5322 for headers and MIME (RFC 2045-2049) for message parts and attachments. Storage formats include MBOX, Maildir, and proprietary formats like PST or EML.

Common uses include data extraction for analytics, search and indexing, compliance and legal discovery, anti-spam and threat detection, data migration between systems, and archival retention.

Security and privacy: handling emaildata involves protection of content and metadata, encryption in transit (TLS) and at rest, and privacy compliance (GDPR, CAN-SPAM). Data quality issues include encoding, character sets, and header spoofing risks.
