Session session = …;
MimeMessage message = new MimeMessage(session);
Based on 83 examples
public class MimeMessage extends Message implements MimePart
This class represents a MIME style email message. It implements
the Message
abstract class and the MimePart
interface.
Clients wanting to create new MIME style messages will instantiate an empty MimeMessage object and then fill it with appropriate attributes and content.
Service providers that implement MIME compliant backend stores may want to subclass MimeMessage and override certain methods to provide specific implementations. The simplest case is probably a provider that generates a MIME style input stream and leaves the parsing of the stream to this class.
MimeMessage uses the InternetHeaders
class to parse and
store the top level RFC 822 headers of a message.
The mail.mime.address.strict
session property controls
the parsing of address headers. By default, strict parsing of address
headers is done. If this property is set to "false"
,
strict parsing is not done and many illegal addresses that sometimes
occur in real messages are allowed. See the InternetAddress
class for details.
RFC 822 header fields must contain only
US-ASCII characters. MIME allows non ASCII characters to be present
in certain portions of certain headers, by encoding those characters.
RFC 2047 specifies the rules for doing this. The MimeUtility
class provided in this package can be used to to achieve this.
Callers of the setHeader
, addHeader
, and
addHeaderLine
methods are responsible for enforcing
the MIME requirements for the specified headers. In addition, these
header fields must be folded (wrapped) before being sent if they
exceed the line length limitation for the transport (1000 bytes for
SMTP). Received headers may have been folded. The application is
responsible for folding and unfolding headers as appropriate.

The "Subject" field is filled in with the original subject
prefixed with "Re:" (unless it already starts with "Re:").
The "In-Reply-To" header is set in the new message if this
message has a "Message-Id" header. The ANSWERED
flag is set in this message.
The current implementation also sets the "References" header
in the new message to include the contents of the "References"
