I've search but can't seem to find a similar problem, never mind an answer. I have a web app running on my laptop (windows 8), tomcat7 and it works fine. It sends out the email as expected. I have the same code running on my linux server, also tomcat7 and I get javax.mail.AuthenticationFailedException.
I've done the Authenticator thing from the start:
...
Authenticator mailAuthenticator = new Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(properties.getProperty("mail.smtp.user"),
properties.getProperty("mail.smtp.password"));
}
};
try {
// Get the default Session object.
Session session = Session.getInstance(properties, mailAuthenticator);
MimeMessage mimeMessage = new MimeMessage(session);
mimeMessage.setSubject("Subject, whoot whoot!");
mimeMessage.setFrom(new InternetAddress(properties.getProperty("mail.smtp.from")));
//This is an overkill
List<String> emailList = new LinkedList<>();
emailList.add("email#example.com");
for(String item : emailList) {
mimeMessage.addRecipients(Message.RecipientType.TO, InternetAddress.parse(item));
}
//The body ).(
StringBuilder sbMsg = new StringBuilder("Some text, etc.\n");
sbMsg.append("more text");
Multipart multipart = new MimeMultipart("alternative");
BodyPart messageBodyPart1 = new MimeBodyPart();
messageBodyPart1.setContent(sbMsg.toString(), "text/plain");
multipart.addBodyPart(messageBodyPart1);
mimeMessage.setContent(multipart);
Transport transport = session.getTransport(properties.getProperty("mail.transport"));
int port = Integer.parseInt(properties.getProperty("mail.smtp.port"));
//Exception happens on the line below
transport.connect(properties.getProperty("mail.smtp.host"),
port,
properties.getProperty("mail.smtp.user"),
properties.getProperty("mail.smtp.password"));
transport.sendMessage(mimeMessage, mimeMessage.getAllRecipients());
return true;
} catch (Exception e) {
//Pokemon exception handling :(
LOG.log(Level.SEVERE, "Error while sending email", e);
}
The exception happens on transport.connect, and there is no description with the exception :(
I've checked the mail.smtp.user and mail.smtp.password and it is exactly the same :s
Any clues where I can start looking?
Just got an emails and text from Google. GMail thought I was trying to hack my account. I'm glad there is a logical answer to this problem :-)

I want to testing send mail using JavaMailSender,the code work fine but when I setting my pc time to the past it throw this exception.
Could not convert socket to TLS
Here is my code
MimeMessageHelper message = new MimeMessageHelper(mimeMessage, "UTF-8");
message.setSubject(subject);
message.setFrom(config.getMailFrom());
message.setTo(recipientEmail);
String htmlContent = templateEngine.process("email.html", ctx);
message.setText(htmlContent, true );
mailSender.send(mimeMessage);
catch (Exception e) {
throw new Exception();
}
I try to turn off the window defender but it didn't work.
My pc does not have any antivirus software or anything like protection software.It's
some kind of JavaMailSender protection or a bug?
I am working with JavaMail for my plugin, within this plugin I am trying to send an email but my issue lies around the client. The client can't handle the plugin connecting to the email server and sending an email it either crashes the entire server or the client gets kicked out. My fix for this was instead of constantly connecting to the email server and sending an email why not simply keep one connection open when the plugin starts and grab that connection when I am wanting to send an email hopefully this will help in allowing the client and server to stay stable without any crashes. If anyone can help me I am just curious on how I can go about keeping a a single connection open and grabbing it when it is needed and then closing it when the plugin gets disabled.
What I have tried:
private Session session;
public void connect() {
String provider = plugin.getConfig().getString("EmailProvider");
String email = plugin.getConfig().getString("Email");
String password = plugin.getConfig().getString("Password");
Properties props = new Properties();
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.host", provider);
props.put("mail.smtp.port", "25");
session = Session.getInstance(props,
new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(email, password);
}
});
}
private boolean checkSession() {
try {
if (session != null) {
return true;
} else {
return false;
}
}
return false;
}
public void sendEmail(String to, String from, String subject, String text) {
if (!checkSession()) {
connect();
System.out.println("connecting");
}
try {
Message message = new MimeMessage(session);
message.setFrom(new InternetAddress(from));
message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(to));
message.setSubject(subject);
message.setText(text);
Transport.send(message);
} catch (MessagingException e) {
e.printStackTrace();
}
}
}
The simple answer is, you can't.
There's no way to force a connection to remain open. Connections can be closed for all sorts of reasons and your program needs to be prepared for that.
You can, however, cache an open connection and reuse it as long as it's still connected. But without knowing what your plugin plugs in to, it's hard to describe the best strategy for that.
Note also that mail servers really don't want you to keep a connection open if you're not using it, which is why they'll close it out from under you if you leave it open but idle for too long. And artificially keeping the connection active won't win you any points with the mail server either.
If your mail server crashes when you connect to it, it's probably time to get a new mail server.
I want to test my Emil Com server and SMTP capacity. So i need to send mail to different Email account from my Application. But i cant not create 10000 mail iD's each time. IS there any simulation tool available to send a Email from my application without creating the Mail id's (Gmail, yahoo etc)
Use this method emailNotification() and implement as per your need. Concatinate all the email_id with a comma seprator abc#abc.com,abc1#abc.com,abc2#abc.com and pass the string to the v_sBCC.
This function might help you out. Thanks..
private void emailNotification(){
String v_sTo;
String v_sFrom;
String v_sBCC = "abc#gmail.com,abc1#gmail.com" //add a number of emails with a Comma separator.
DataSource v_objSource;
Properties v_objProperties;
Session v_objSession;
MimeMessage v_sMessage;
BodyPart v_objMessageBodyPart;
Multipart v_objMultipart;
try {
v_sFrom = "Set From Name To Show User that From which Email you received Mail";
v_objProperties = new Properties();
v_objProperties.put("mail.smtp.host", smtp.google.com);
v_objProperties.put("mail.smtp.auth", "true");
v_objProperties.put("mail.debug", "false");
v_objProperties.put("mail.smtp.port", 25);
v_objProperties.put("mail.smtp.socketFactory.port", 25);
v_objProperties.put("mail.smtp.starttls.enable", "true");
v_objProperties.put("mail.transport.protocol", "smtp");
v_objSession = Session.getInstance(v_objProperties, new Authenticator() {
#Override
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication("gmail.id", "password");
}
});
v_sMessage = new MimeMessage(v_objSession);
v_sMessage.setFrom(new InternetAddress(v_sFrom, "Your Company Name"));
v_sMessage.addRecipient(Message.RecipientType.TO, new InternetAddress(v_sTo));
v_sMessage.addRecipient(Message.RecipientType.BCC, new InternetAddress(v_sBCC));
v_sMessage.setSubject("Set Your Own Subject");
v_sMessage.setText("Set Your Own Body");
Transport.send(v_sMessage);
} catch (MessagingException v_exException) {
v_exException.printStackTrace();
} catch (UnsupportedEncodingException v_exException) {
v_exException.printStackTrace();

I have used java mail API for sending mail in my application using java and web driver.My requirement is to send a mail whenever a link/url is down.Even though mail is send when i give url incorrectly ,but at the same time if a url is not loading due any other issue (page not found), found that mail is not getting send.
public void SendMail(String url,String str)
{
try
{
Sheet mailsheet = w.getSheet("mail");
String from = mailsheet.getCell(0,1).getContents().toString().trim();
String toEmailID=mailsheet.getCell(1,1).getContents().toString().trim();
Properties props = new Properties();
String mailprotocol = mailsheet.getCell(2,1).getContents().toString().trim();
String mailprotocoltype = mailsheet.getCell(3,1).getContents().toString().trim();
String mailhost = mailsheet.getCell(4,1).getContents().toString().trim();
String mailhostip = mailsheet.getCell(5,1).getContents().toString().trim();
String mailport=mailsheet.getCell(6,1).getContents().toString().trim();
String mailportid=mailsheet.getCell(7,1).getContents().toString().trim();
props.put(mailprotocol,mailprotocoltype);
props.put(mailhost,mailhostip);
props.put(mailport,mailportid);
javax.mail.Session mailSession =javax.mail.Session.getInstance(props);
Message msg = new MimeMessage(mailSession);
msg.setFrom(new InternetAddress(from));
msg.setRecipients(Message.RecipientType.TO,InternetAddress.parse(toEmailID));
msg.setSubject("Test Summary");
msg.setContent("<html><body>Dear Admin,<br> Website page "+ "<b><i>"+url + "</b></i>"+" cannot be loaded due to the following :<br> <br></body></html>"+str,"text/html");
Transport.send(msg);
System.out.println("Mail is successfully sent to Recipient address with Error information.");
}
catch(Exception e)
{
//System.out.println(e);
System.out.println("Mail cannot be send to Recipient address due to connection error");
}
}
public void x() {
SendMail(url,driver.getTitle());
}
The answer is probably in the bit of code you don't show us : the part where you test the URL.
The response code for a wrong domain name is different from the response code due to a page not found. Also, depending on the system you're targetting, it's possible that page not found are redirected to the index page, making detection even more difficult.
I'm writing a small Java app using JavaMail that sends the user an automated email. They can choose between (for now) two ports: 25 and 587. The port can be selected via a radio button on the GUI.
I added a test button to allow the user to test the email settings (including port). However, for some reason, once the user tries to send a test email, the port can't be changed. Javamail will always use the port of the original test email.
Example: User tries to send an email on port 25 and JavaMail says it can not connect on port 25 (for example, the SMTP host uses another port). User clicks port 587, and tries to send a new email. JavaMail throws an error saying it can not connect on port 25, again.
I'm kind of stumped as to why. Every time a new test email is sent an entirely new SendMailUsingAuthentication object is created. Within that class the properties are always reset to the proper port. Whenever I debug, as far as I can see, all variables are correct and associated with the correct port. Is there something going on inside of Transport that I'm missing?
In the front end GUI:
private void testButtonActionPerformed(java.awt.event.ActionEvent evt) {
int port = port25RadioButton.isSelected() ? PORT_25 : PORT_587;
notifier = new SendMailUsingAuthentication(hostNameTextField.getText(),
userTextField.getText(), getPassword(), emailTextField.getText().split(","),port);
Thread wait = new Thread(new Runnable() {
public void run() {
try {
changeStatusText("Sending test email...");
notifier.postTestMail();
changeStatusText("Test email sent.");
} catch (AddressException ex) {
changeStatusText("Error. Invalid email address name.");
} catch (MessagingException ex) {
changeStatusText("SMTP host connection refused.");
System.err.println(ex.getMessage());
} catch (Exception ex) {
System.err.println(ex);
}
}
});
wait.start();
}
In the email sender class:
public void postTestMail() throws MessagingException, AddressException{
String[] testReciever = new String[1];
testReciever[0] = emailList[0];
postMail(testReciever, "Test email.", "Your email settings are successfully set up.", emailFromAddress);
}
private void postMail(String recipients[], String subject,
String message, String from) throws MessagingException, AddressException {
//Set the host smtp address
Properties props = new Properties();
props.put("mail.smtp.port", smtpPort);
props.put("mail.smtp.host", smtpHostName);
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.starttls.enable", true);
Authenticator auth = new SMTPAuthenticator();
Session session = Session.getDefaultInstance(props, auth);
session.setDebug(false);
// create a message
Message msg = new MimeMessage(session);
// set the from and to address
InternetAddress addressFrom = new InternetAddress(from);
msg.setFrom(addressFrom);
InternetAddress[] addressTo = new InternetAddress[recipients.length];
for (int i = 0; i < recipients.length; i++) {
addressTo[i] = new InternetAddress(recipients[i]);
}
msg.setRecipients(Message.RecipientType.TO, addressTo);
// Setting the Subject and Content Type
msg.setSubject(subject);
msg.setContent(message, "text/plain");
Transport.send(msg);
}
This happens because you're using getDefaultInstance() which says:
Get the default Session object. If a default has not yet been setup, a new Session object is created and installed as the default.
And that the Properties argument is "used only if a new Session object is created."
So the first time you invoke getDefaultInstance it uses your specified port. After that, the Session has already been created, and subsequent calls to getDefaultInstance will return that same session, and ignore the changed properties.
Try using Session.getInstance() instead of getDefaultInstance(), which creates a new Session each time, using the supplied properties.
It pays to read the javadocs very carefully.
Tip for anyone else still having issues, we were using Session.getInstance and the port was still defaulting to 25.
Turns out, we were setting the prop value as a Long when it needs to be a String
It didn't error, warn or log, just defaulted to 25.
I think "Transport.send(msg)" wont be taking into account the connection details that you are providing in your properties. It will use its connection that is defined by default.
The java doc says
"Note that send is a static method that creates and manages its own connection. **Any connection associated with any Transport instance used to invoke this method is ignored and not used. This method should only be invoked using the form Transport.send(msg);, and should never be invoked using an instance variable. "**
Instead, I have tried with Transport.connect(smtphost,smtpport,user,password) and it works pretty well.
Plz compare two methods of Session class: Session.getDefaultInstance(Properties, Authenticator) and Session.getInstance(Properties, Authenticator)
