JavaMail - Sender Address rejected: Access Denied

Ok, I don't know what else to do. This code worked perfectly fine a week ago when I wrote and tested it. Then I embedded it into my program and realised I kept getting exceptions. Everything seems normal. The sender address is legit. The recipient addresses I used to test it are legit. What is wrong? I'm so frustrated:

private String outgoingMailServer = "smtp.mail.yahoo.com";

boolean debug = true;

            //set the host outgoing mail smtp server.
            Properties properties = new Properties();
            properties.put("mail.smtp.host", outgoingMailServer);
            properties.put("mail.smtp.auth", "true");

            Authenticator authenticator = new SMTPAuthentication();
            Session session = Session.getDefaultInstance(properties, authenticator);

            session.setDebug(debug);

            //create a message session
            Message msg = new MimeMessage(session);

            //set the addresses, to and from
            InternetAddress fromAddress;
            fromAddress = new InternetAddress(emailFromAddress);
            msg.setFrom(fromAddress);

            //since mail can be sent to more than one recipient, create loop
            //to add all addresses into InternetAddress, addressTo.
            //InternetAddress[] toAddress = new InternetAddress[recipients.length];
            InternetAddress[] toAddress = new InternetAddress[recipients.size()];
            for (int i = 0; i < recipients.size(); i++) {
                toAddress[i] = new InternetAddress(recipients.get(i));
            }
            msg.setRecipients(Message.RecipientType.TO, toAddress);

            //set the subject and content type
            msg.setSubject(emailSubject);
            msg.setContent(actualMessage, "text/html; charset=utf-8");

            //send the email
            Transport.send(msg);

The exception is thus:

javax.mail.SendFailedException: Invalid Addresses;
  nested exception is:
    com.sun.mail.smtp.SMTPAddressFailedException: 554 5.7.1 <blank@yahoo.com>: Sender address rejected: Access denied

    ... 5 more

Any help would be most appreciated. Thanks!

Finally figured out a work-around (though I still can't understand why there's a problem in the first place, seeing as the codes used to work. Anyways...)

private String outgoingMailServer = "smtp.mail.yahoo.com";    
boolean debug = false;

//set the host outgoing mail smtp server.
Properties properties = new Properties();
properties.put("mail.smtp.host", outgoingMailServer);
properties.put("mail.smtps.auth", "true");

Authenticator authenticator = new SMTPAuthentication();
Session session = Session.getDefaultInstance(properties, authenticator);
session.setDebug(debug);

//create a message session
Message msg = new MimeMessage(session);

//set the addresses, to and from
InternetAddress fromAddress;
fromAddress = new InternetAddress(emailFromAddress);
msg.setFrom(fromAddress);

//since mail can be sent to more than one recipient, create loop
//to add all addresses into InternetAddress, addressTo.
//InternetAddress[] toAddress = new InternetAddress[recipients.length];
InternetAddress[] toAddress = new InternetAddress[recipients.size()];
for (int i = 0; i < recipients.size(); i++) {
    toAddress[i] = new InternetAddress(recipients.get(i));
}
msg.setRecipients(Message.RecipientType.TO, toAddress);

//set the subject and content type
msg.setSubject(emailSubject);
msg.setContent(actualMessage, "text/html; charset=utf-8");

//send the email
Transport transport = session.getTransport("smtps");
transport.connect(outgoingMailServer, 465, emailUserName, emailPassword);
transport.sendMessage(msg, msg.getAllRecipients());
transport.close();

//email sent
//note, this does not necessarily mean the email was delivered. The
//sysetm has no control over that
emailSent = true;

You'll find that the main difference between the codes in the question and these ones are:

Transport.send(msg);

and

Transport transport = session.getTransport("smtps");
transport.connect(outgoingMailServer, 465, emailUserName, emailPassword);
transport.sendMessage(msg, msg.getAllRecipients());
transport.close();

Turns out, a Transport object had to be created and connected using the proper credentials (port number, username, password, and mail server).

Also, I did a process of elimination and found out that as long as you have this:

Transport transport = session.getTransport("smtps");
transport.connect(outgoingMailServer, 465, emailUserName, emailPassword);
transport.sendMessage(msg, msg.getAllRecipients());
transport.close();

you don't need this:

Authenticator authenticator = new SMTPAuthentication();
Session session = Session.getDefaultInstance(properties, authenticator);

The above could as well be:

Session session = Session.getDefaultInstance(properties, null);

Anyway, that's the answer. You can also alter this answer for gmail. Just be sure to change the outgoing mail server to gmail's, as well as the from email address, username and password, and you'll be just fine :)
