Class MimeMessage

java.lang.Object

javax.mail.Message

javax.mail.internet.MimeMessage

All Implemented Interfaces:

MimePart, Part

Direct Known Subclasses:

NNTPMessage, gnu.mail.providers.ReadOnlyMessage

public class MimeMessage
extends Message
implements MimePart

A MIME mail message. This may be a top-level part, or the content of a MIME body part with a "message/rfc822" Content-Type.

The string representation of RFC822 and MIME header fields must contain only US-ASCII characters. Non US-ASCII characters must be encoded as per the rules in RFC 2047. This class does not enforce those rules; the caller is expected to use MimeUtility to ensure that header values are correctly encoded.
