My program was working correctly last night; I could send email from any address to any other, but now this error is occuring:
javax.mail.SendFailedException: Sending failed;
nested exception is:
class javax.mail.MessagingException: Could not connect to SMTP host: localhost, port: 25;
nested exception is:
java.net.ConnectException: Connection refused
at javax.mail.Transport.send0(Transport.java:218)
at javax.mail.Transport.send(Transport.java:80)
at SendEmail.main(SendEmail.java:49)
Line 49 is:
Transport.send(message);
Can anyone help me fix this error?
My operating system is : Linux,Fedora 16 -kernel: 3.3.7
Could not connect to SMTP host: localhost, port: 25;
SMTP must be not running on your system or disabled for you as user. Check with your system administrator and get it enabled for you.
To check if SMTP is working on your Linux system, try the following commands:
To simply verify Sendmail is running, try: netstat -an | grep 25
Use telnet to connect to port 25 of smtp server: telnet <yourhost-or-ipnumber> 25
a. Connecting To localhost...Could not open connection to the host, on port 25: Connect failed.
b. if you or your ip is blocked, you would see error message something like this:
220-localhost ESMTP Exim 4.63 #1 Fri, 01 Jun 2012 19:35:30 +0530
220-We do not authorize the use of this system to transport unsolicited, and/or bulk e-mail.
echo -e "quit" | nc localhost 25
localhost.localdomain [127.0.0.1] 25 (?) : Connection refused
mail at shell prompt.
and, may be more...
You should check that sendmail daemon is started and is available always.
And if you have access to any other SMTP servers, try to send mail using their SMTP host name, to check if your code snippet is working.
Example : String host = "smtp.gmail.com";
it was because my SendMail Service Stopped working.
to enable it : try this command in shell(as root).
service sendmail start
U on right way..just change Property setting and Session sentence .my java mail work Fine...
final String username = "abc#gmail.com";
final String password = "****";
Properties props = new Properties();
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.host", "smtp.gmail.com");
props.put("mail.smtp.port", "587");
Session session = Session.getInstance(props, new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(username, password);
}
});

Im using the XAMPP Control Panel to run a Mercury Server. The Ports are 25,79,105,106,110,143 and 2224. Im new to this so maybe someone can push me in the right direction.
You must uncheck "Do not permit SMTP relaying of non-local mail" option.
See the link: uncheck option
Please check below two things.
1).where the host mail server is running. If it is running in local machine then set the host address as 0.0.0.0
2.If it is external mail server, check the mail credentials like username, password, host.
I think 553 is "denied error" from server, that means you have not provided correct credential .
I am facing issue while sending mails programmatically using Java. I confirmed from the network team that sending mails through Java is blocked using firewall.
but am able to get the response from telnet in my windows command prompt. Please find the details below.
Code used to send mail using Javax Mail:
public static void main(String[] args) throws MessagingException {
String host = "mailhost.xxx";
String to = "abc#xyz.edu";
String from = "cde#xyz.edu";
String subject = "test";
String messageText = "body test";
Properties props = System.getProperties();
props.put("mail.host", host);
props.put("mail.transport.protocol", "smtp");
props.put("mail.smtp.port", "25");
// If using authentication, otherwise comment out
props.put("mail.smtp.auth", "true");
// Gmail requires TLS, your server may not
props.put("mail.smtp.starttls.enable", "true");
// Session mailSession = Session.getDefaultInstance(props, null);
Session mailSession = Session.getInstance(props, new javax.mail.Authenticator() {
#Override
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication("username", "password");
}
});
Message msg = new MimeMessage(mailSession);
msg.setFrom(new InternetAddress(from));
InternetAddress[] address = { new InternetAddress(to) };
msg.setRecipients(Message.RecipientType.TO, address);
msg.setSubject(subject);
msg.setSentDate(new Date());
msg.setText(messageText);
Transport transport = mailSession.getTransport("smtp");
// connect with authentication
// transport.connect(host,"myUsername" , "myPassword");
// connect without authentication
transport.connect();
transport.sendMessage(msg, address);
transport.close();
System.out.println("Mail was sent to " + to);
System.out.println(" from " + from);
System.out.println(" using host " + host + ".");
}

Let me know any possible solution to resolve the above issue.
Since :
the source exception points to a permissions issue,
but you can connect from command line using telnet
that's not a network firewall issue.
You also ruled out the related Java 7 bug.
So, the problem probably comes from your local Windows Firewall, or whatever Antivirus/firewall you're using. It may grant permissions to telnet, but not to Java.
Try to disable all your local firewall/antivirus, and check if java can successfully connect. If so, re-enable your firewall, and create an exception rule to allow connections to port 25 for your Java application.
Posting an alternate solution for my above issue:
As we were using Exchange accounts we were able to send the mails programmatically using EWS (Exchange Web Services) API.

Had the same issue. It's an MS Exchange error that you receive. You are probably not allowed to use your email to send an email via a relay. The administrator of the Exchange server needs to give the rights to do that.
It has nothing to do with a configuration problem on the Java side.
It looks like the problem in how you do the session part...
try doing this:
private Properties emailPorperties;
...
...
emailPorperties = new Properties();
emailPorperties.put("mail.smtp.host", "your host");
emailPorperties.put("mail.smtp.socketFactory.port", "your port");
emailPorperties.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
emailPorperties.put("mail.smtp.auth", "true");
emailPorperties.put("mail.smtp.port", "your port");
emailPorperties.put("mail.smtp.ssl.enable", "true");
emailSession = Session.getInstance(emailPorperties, new Authenticator() {
#Override
protected PasswordAuthentication getPasswordAuthentication() {
System.out.println("Authenticating");
return new PasswordAuthentication(USER_NAME, PASSWORD);
}
});
Hello i've got the same issue in the past.
So to solve it i have to connect on the webmail of my outlook or exchage and i noticed that these connexions were stopped by the server so inside i confirm that these transactions was mine.
So u have also to do it usually every 2 month in my case.
The problem is not in the code. The problem occurs because something is wrong with the configuration of the mailboxes I believe.
Same issue resolve by enabling IMAP of the sender email account in Exchange Control Panel (ECP) of outlook mail admin.
Go to your Microsoft admin account and turn off the multi-factor authentication.
By default it is enabled. Once you disable the multi-factor authentication then it works fine for me.
I had a similar issue and in my case, the issue was 'outlook password got expired'.
As I had it logged in default I did not have any issue while logging in to my mail.
I tried logging in to incognito mode and see if my logging asked for an additional layer for logging like multi-factor auth, And when logged in from the incognito tab it asked to change the password with a popup stating 'password got expired'.
I then updated the new password and it started to work fine !!
I am getting this error when I try to send an email from Java web app hosted on AWS.
I have already tried to change SMTP server to smtp.live.com and also smtp-mail.outlook.com, none of those work.
Can it be some AWS config? It runs on Ubuntu. (There are no outbound restrictions on the server itself, there might be some on Java server though)
Code for sending the email:
final String username = smtpUsername;
final String password = smtpPwd;
Properties props = new Properties();
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.host", smtpHost);
props.put("mail.smtp.port", smtpPort);
Session session = Session.getInstance(props, new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(username, password);
}
});
try {
Message message = new MimeMessage(session);
message.setFrom(new InternetAddress(smtpUsername));
message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(sendTo));
message.setSubject(subject);
message.setContent(content);
Transport.send(message);
System.out.println("Sent");
} catch (MessagingException e) {
e.printStackTrace();
}
The most interesting part of this is, that it works from my local computer...(but only when I disable Avast)

I have tried to set up the AWS SMTP (SES) and I am getting the same error, even after I followed the documentation, I also added the email from which I was sending and to which I was sending to the verified emails (whitelist):
javax.mail.MessagingException: Unknown SMTP host: "email-smtp.eu-west-1.amazonaws.com";
try doing a dig from a bash shell from the ubuntu machine
dig email-smtp.eu-west-1.amazonaws.com
what are you getting. from what I can see, it might be a DNS problem.
I am trying to send email to gmail using java. I am using this code.
final String username = "xyz#gmail.com";
final String password = "**********";
Properties props = new Properties();

props.put("mail.smtp.starttls.enable","true");

Message message = new MimeMessage(session);
message.setFrom(new InternetAddress("xyz#gmail.com"));
message.setRecipient(Message.RecipientType.TO,newInternetAddress("abcdef#gmail.com"));
message.setSubject("First email to using java");
message.setContent("<h:body style =background-color:white> This is a test mail sent using java" + "</body>","text/html; charset=utf-8");
Transport.send(message);
System.out.println("Message Sent");
But When i run the above code it shows follwoing error:
Exception in thread "main" com.sun.mail.util.MailConnectException: Couldn't connect to host, port: smtp.gmail.com, 587; timeout -1;
I have an Internet connection which uses proxy server and requires authentication. Is this error because of Proxy or there is some problem in my code. Please tell me how to resolve it.
JavaMail can't use a web proxy server directly, although it can use a SOCKS proxy server. If you only have a web proxy server, programs like Corkscrew can help.
You can setup SOCKS proxy server in JavaMail with like this:
Properties p = System.getProperties();
p.setProperty("proxySet","true");
p.setProperty("socksProxyHost","192.168.1.1");
p.setProperty("socksProxyPort","1234");
Yes, it's because of your proxy server.
How do I configure JavaMail to work through my proxy server?
