The JavaMail<sup><font size="-2">TM</font></sup> API
provides classes that model a mail system.
The <code>javax.mail</code> package defines classes that are common to
all mail systems.
The <code>javax.mail.internet</code> package defines classes that are specific
to mail systems based on internet standards such as MIME, SMTP, POP3, and IMAP.
The JavaMail API includes the <code>javax.mail</code> package and subpackages.
<P>
For an overview of the JavaMail API, read the JavaMail specification
<A HREF="../../../JavaMail-1.4.pdf" TARGET="_top">
included in the download bundle</A> or
<A HREF="http://java.sun.com/products/javamail/JavaMail-1.4.pdf" TARGET="_top">
available on the JavaMail web site</A>.
<P>
The code to send a plain text message can be as simple as the following:
<PRE>
Properties props = new Properties();
props.put("mail.smtp.host", "my-mail-server");
props.put("mail.from", "me@example.com");
Session session = Session.getInstance(props, null);
try {
MimeMessage msg = new MimeMessage(session);
msg.setFrom();
msg.setRecipients(Message.RecipientType.TO,
"you@example.com");
msg.setSubject("JavaMail hello world example");
msg.setSentDate(new Date());
msg.setText("Hello, world!\n");
Transport.send(msg);
} catch (MessagingException mex) {
System.out.println("send failed, exception: " + mex);
}
</PRE>
The JavaMail download bundle contains many more complete examples
in the "demo" directory.
<P>
Don't forget to see the
<A HREF="http://java.sun.com/products/javamail/FAQ.html" TARGET="_top">
JavaMail API FAQ</A>
for answers to the most common questions.
The <A HREF="http://java.sun.com/products/javamail/" TARGET="_top">
JavaMail web site</A>
contains many additional resources.
<P>
The JavaMail API supports the following standard properties,
which may be set in the <code>Session</code> object, or in the
<code>Properties</code> object used to create the <code>Session</code> object.
The properties are always set as strings; the Type column describes
how the string is interpreted. For example, use
<PRE>
props.put("mail.debug", "true");
</PRE>
to set the <code>mail.debug</code> property, which is of type boolean.
<P>
<TABLE BORDER>
<TR>
<TH>Name</TH>
<TH>Type</TH>
<TH>Description</TH>
</TR>
<TR>
<TD>mail.debug</TD>
<TD>boolean</TD>
<TD>
The initial debug mode.
Default is false.
</TD>
</TR>
<TR>
<TD>mail.from</TD>
<TD>String</TD>
<TD>
The return email address of the current user, used by the
<code>InternetAddress</code> method <code>getLocalAddress</code>.
</TD>
</TR>
<TR>
<TD>mail.mime.address.strict</TD>
<TD>boolean</TD>
<TD>
The MimeMessage class uses the <code>InternetAddress</code> method
<code>parseHeader</code> to parse headers in messages. This property
controls the strict flag passed to the <code>parseHeader</code>
method. The default is true.
</TD>
</TR>
<TR>
<TD>mail.host</TD>
<TD>String</TD>
<TD>
The default host name of the mail server for both Stores and Transports.
Used if the <code>mail.<i>protocol</i>.host</code> property isn't set.
</TD>
</TR>
<TR>
<TD>mail.store.protocol</TD>
<TD>String</TD>
<TD>
Specifies the default message access protocol. The
<code>Session</code> method <code>getStore()</code> returns a Store
object that implements this protocol. By default the first Store
provider in the configuration files is returned.
</TD>
</TR>
<TR>
<TD>mail.transport.protocol</TD>
<TD>String</TD>
<TD>
Specifies the default message access protocol. The
<code>Session</code> method <code>getTransport()</code> returns a Transport
object that implements this protocol. By default the first Transport
provider in the configuration files is returned.
</TD>
</TR>
<TR>
<TD>mail.user</TD>
<TD>String</TD>
<TD>
The default user name to use when connecting to the mail server.
Used if the <code>mail.<i>protocol</i>.user</code> property isn't set.
</TD>
</TR>
<TR>
<TD>mail.<i>protocol</i>.class</TD>
<TD>String</TD>
<TD>
Specifies the fully qualified class name of the provider for the
specified protocol. Used in cases where more than one provider
for a given protocol exists; this property can be used to specify
which provider to use by default. The provider must still be listed
in a configuration file.
</TD>
</TR>
<TR>
<TD>mail.<i>protocol</i>.host</TD>
<TD>String</TD>
<TD>
The host name of the mail server for the specified protocol.
Overrides the <code>mail.host</code> property.
</TD>
</TR>
<TR>
<TD>mail.<i>protocol</i>.port</TD>
<TD>int</TD>
<TD>
The port number of the mail server for the specified protocol.
If not specified the protocol's default port number is used.
</TD>
</TR>
<TR>
<TD>mail.<i>protocol</i>.user</TD>
<TD>String</TD>
<TD>
The user name to use when connecting to mail servers
using the specified protocol.
Overrides the <code>mail.user</code> property.
</TD>
</TR>
</TABLE>
<P>
The JavaMail API also supports several System properties;
see the {@link javax.mail.internet} package documentation
for details.
<P>
The JavaMail reference
implementation from Sun includes protocol providers in subpackages of
<code>com.sun.mail</code>. Note that the APIs to these protocol
providers are not part of the standard JavaMail API. Portable
programs will not use these APIs.
<P>
Nonportable programs may use the APIs of the Sun protocol providers
by (for example) casting a returned <code>Folder</code> object to a
<code>com.sun.mail.imap.IMAPFolder</code> object. Similarly for
<code>Store</code> and <code>Message</code> objects returned from the
standard JavaMail APIs.
<P>
The Sun protocol providers also support properties that are specific to
those providers. The package documentation for the
{@link com.sun.mail.imap IMAP}, {@link com.sun.mail.pop3 POP3},
and {@link com.sun.mail.smtp SMTP} packages provide details.
