Getting error while sending mail in java-Collection of common programming errors
Bhaskar SharmaI was trying to send mail using java. The code i was using worked when I used it with GMail’s SMTP server (“smtp.gmail.com”). But when I changed the code (smtp_host_name, smtp_port properties and authentication UserID/Pwd) to send email through the SMTP server of my ISP provider, this code failed.
Here is my code-
String host = "smtp server host of my isp provider"; Properties props = System.getProperties(); props.put("mail.smtp.host", host); props.put("mail.debug", "true"); props.put("mail.transport.protocol.", "smtp"); props.put("mail.smtp.auth", "true"); props.put("mail.smtp.port", "25"); props.put("mail.smtp.starttls.enable","true"); Session mailSession = Session.getDefaultInstance(props, null); mailSession.setDebug(sessionDebug); 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.setContent(messageText, "text/html"); Transport transport = mailSession.getTransport("smtp"); transport.connect(host, user, pass);And i am getting this error-
javax.mail.MessagingException: Exception reading response; nested exception is: javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection?The problem is i am able to send mails from the same code from my system workspace. But after i upload the war file to host, i get the above error. I think i disabled SSL but still getting this error. Can someone please help. Its urgent…
I followed the steps given below but still i am getting the same error. Here is my code now-
String host = "mail.myweb.com", user = emailUser, pass = emailPasswd; String to = emailID; String from = emailFrom; String subject = subj; String messageText = message; boolean sessionDebug = true; Properties props = System.getProperties(); props.put("mail.smtp.host", host); props.put("mail.debug", "true"); props.put("mail.transport.protocol", "smtp"); props.put("mail.smtp.auth", "true"); props.put("mail.smtp.port", "25"); Session mailSession = Session.getDefaultInstance(props, null); mailSession.setDebug(sessionDebug); 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.setContent(messageText, "text/html"); Transport transport = mailSession.getTransport("smtp"); transport.connect(host, user, pass); try { transport.sendMessage(msg, msg.getAllRecipients()); } catch (Exception e) { System.out.println("Error" + e.getMessage()); } transport.close(); }Here is the full stacktrace

Ernest Friedman-HillThis line
props.put("mail.smtp.starttls.enable","true");is enabling SSL on this connection; make it false instead , or just take it out.
Also the dot at the end of this property name is suspicious, although probably innocuous:
props.put("mail.transport.protocol.", "smtp");
mathiHi try to add following properties for non ssl smtp connection
props.put("mail.smtp.starttls.enable","false"); props.put("mail.smtp.socketFactory.port", "25"); props.put("mail.smtp.socketFactory.class", ""); props.put("mail.smtp.socketFactory.fallback", "false");for example the ssl connection properties are
Properties props = new Properties(); props.put("mail.smtp.username", "[email protected]"); props.put("mail.smtp.password", "password"); props.put("mail.smtp.protocol", "smtp"); props.put("mail.smtp.host", "smtp.gmail.com"); props.put("mail.smtp.port", "587"); props.put("mail.smtp.starttls.enable","true"); props.put("mail.smtp.auth", "true"); props.put("mail.smtp.socketFactory.port", "587"); props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory"); props.put("mail.smtp.socketFactory.fallback", "false");Non ssl properties are
Properties props = new Properties(); props.put("mail.smtp.user", "[email protected]"); props.put("mail.smtp.password", "password"); props.put("mail.smtp.protocol", "smtp"); props.put("mail.smtp.host", "smtp.mydomain.com"); props.put("mail.smtp.port", "25"); props.put("mail.smtp.starttls.enable","false"); props.put("mail.smtp.auth", "true"); props.put("mail.smtp.socketFactory.port", "25"); props.put("mail.smtp.socketFactory.class", ""); props.put("mail.smtp.socketFactory.fallback", "false");
RavinderYou need to get a
Transportobject withsmtpsprotocol. Use Java Mail API version 1.4.1 or later. I am not sure if this was supported in earlier versions.Each of
smtp.jarandimap.jarcontains a resource file namedjavamail.providerswith following entries:# JavaMail SMTP provider Sun Microsystems, Inc protocol=smtp; type=transport; class=com.sun.mail.smtp.SMTPTransport; vendor=Sun Microsystems, Inc; protocol=smtps; type=transport; class=com.sun.mail.smtp.SMTPSSLTransport; vendor=Sun Microsystems, Inc; # JavaMail IMAP provider Sun Microsystems, Inc protocol=imap; type=store; class=com.sun.mail.imap.IMAPStore; vendor=Sun Microsystems, Inc; protocol=imaps; type=store; class=com.sun.mail.imap.IMAPSSLStore; vendor=Sun Microsystems, Inc;These resources are loaded when you create a mail session object.
