Mime4j can be used to parse e-mail message streams in plain link:https://datatracker.ietf.org/doc/html/rfc822[rfc822] and MIME format and to build a tree representation of an e-mail message.

The parser uses a callback mechanism to report parsing events such as the start of an entity header, the start of a body. The parser has been designed to be extremely tolerant against messages violating the standards.

Mime4j can also be used to build a tree representation of an e-mail message via the DOM API.
