Hi
I started learning about java mail.
I am trying with this code

<%@ page import="java.util.Properties,javax.mail.*,javax.mail.internet.*"%>

<% String smtpHost = "crisdev";
String from = "mmalviya@crsl.com";
String to = "mmalviya@crsl.com";

// Get system properties
Properties props = System.getProperties();

// Setup mail server
props.put("mail.smtp.host", smtpHost);

// Get session
Session s =
Session.getDefaultInstance(props, null);

// Define message

MimeMessage message = new MimeMessage(s);
message.setFrom(new InternetAddress(from));
message.addRecipient(Message.RecipientType.TO,
new InternetAddress(to));
message.setSubject("Hello, JDC");
message.setText("Welcome to the JDC");
// Send message
Transport.send(message);
%>

But I am getting this exception.

javax.servlet.ServletException: Sending failed;
nested exception is:
javax.mail.SendFailedException: Invalid Addresses;
nested exception is:
javax.mail.SendFailedException: 550 5.7.1 Unable to relay for mmalviya@crsl.com

org.apache.jasper.runtime.PageContextImpl.doHandlePageException(PageContextImpl.java:848)
org.apache.jasper.runtime.PageContextImpl.handlePageException(PageContextImpl.java:781)


Please suggest me with appropriate solution and good link for learning java mail.
Thanks
Mahesh Malviya

Is your mail server called "crisdev" set up to allow email relaying? These days, most servers don't allow that, in order to reduce spam. You might need to set it up so that it recognizes @crsl.com email adresses as its "own" addresses (which it seems not to do now).
 
It is sorta covered in the JavaRanch Style Guide.
