Send e-mail with Java using hotmail account
<p>I'm doing a web application for send e-mails with a hotmail account. This is my code:</p>

<pre><code>props.put("mail.transport.protocol", "smtp");
props.put("mail.smtp.host", "smtp.live.com");
props.put("mail.smtp.auth", true);
props.put("mail.smtp.port", "587");
props.put("mail.smtp.user", "mail@hotmail.com");
props.put("mail.smtp.pwd", pass);
props.put("mail.debug", true);
props.put("mail.smtp.starttls.enable", "true");

Session session = Session.getDefaultInstance(props);

session.setDebug(true);

try {
    MimeMessage mimeMessage = new MimeMessage(session);
    mimeMessage.setFrom(new InternetAddress("othermail@otherserver.com"));
    mimeMessage.addRecipient(Message.RecipientType.TO, new InternetAddress("mail@hotmail.com"));
    mimeMessage.setSubject(subject);
    mimeMessage.setContent(message, "text/html; charset=UTF-8");
    mimeMessage.setSentDate(new Date());

    SMTPTransport transport = (SMTPTransport) session.getTransport("smtp");
    transport.connect("smtp.live.com", "mail@hotmail.com", pass);
    transport.sendMessage(mimeMessage, mimeMessage.getAllRecipients());
    transport.close();
} catch (MessagingException e) {
    ret = false;}
</code></pre>

<p>When I use this code in local everything works but when I deploy my application on my hosting server appears the follow trace:</p>

</code></pre>

<p>I am quite sure that the account credentials are correct but the authentication fails.
Also I have to say that when I try to do this I receive an e-mail of microsoft says there has been a fraudulent attempt to start session but when I execute the code in local I don't receive this e-mail.
I looked at the page account information and the securty &amp; Privacity section, see my recent activity appears challenge security about this try of send e-mail. In this information the device and platform is unknow and the ip is the of my hosting.
There any way to do this?</p>
