Javamail using outlook in corporation

jakarta-mail, java

Solution

The code is working fine the reason it was giving error was because i was not given rights to SMTP server hence the exception shown, after access was provisioned the mail was sent.

Problem

I am using javamail for the first time and having some exceptions which i dont understand i have seen some of those errors in other questions here as well but the answers to them does not help me. here is my code. ``` final String username = "imsan1@cdcpk.com"; final String password = "**********"; Properties props = System.getProperties(); props.put("mail.smtp.auth", "true"); props.put("mail.smtp.host", "10.1.136.26"); props.put("mail.smtp.port", "25"); props.put( "mail.smtp.user" , username ); props.put( "mail.smtp.password" , password ); Session session = Session.getInstance(props, new SmtpAuthenticator(username, password) ); try { Message message = new MimeMessage(session); message.setFrom(new InternetAddress("imsan1@cdcpk.com")); message.setRecipients(Message.RecipientType.TO, InternetAddress.parse("immni1@cdcpk.com")); message.setSubject("Testing Subject"); message.setText("Dear Mail Crawler," + "\n\n No spam to my email, please!"); Transport.send(message); System.out.println("Done"); } catch (MessagingException e) { throw new RuntimeException(e); } } ``` SmtpAuthenticator ``` import javax.mail.Authenticator; import javax.mail.PasswordAuthentication; class SmtpAuthenticator extends Authenticator { String user; String pw; public SmtpAuthenticator (String username, String password) { super(); this.user = username; this.pw = password; } public PasswordAuthentication getPasswordAuthentication() { return new PasswordAuthentication(user, pw); } } ``` Error log is ``` Exception in thread "main" java.lang.RuntimeException: javax.mail.AuthenticationFailedException: 250-CDC-HO-CAS1.cdcpk.com Hello [10.1.34.74] 250-SIZE 37748736 250-PIPELINING 250-DSN 250-ENHANCEDSTATUSCODES 250-STARTTLS 250-X-ANONYMOUSTLS 250-AUTH NTLM 250-X-EXPS GSSAPI NTLM 250-8BITMIME 250-BINARYMIME 250-CHUNKING 250 XRDST at org.cdc.eipo.bean.investorsetup.EmailController.main(EmailController.java:64) Caused by: javax.mail.AuthenticationFailedException: 250-CDC-HO-CAS1.cdcpk.com Hello [10.1.34.74] 250-SIZE 37748736 250-PIPELINING 250-DSN 250-ENHANCEDSTATUSCODES 250-STARTTLS 250-X-ANONYMOUSTLS 250-AUTH NTLM 250-X-EXPS GSSAPI NTLM 250-8BITMIME 250-BINARYMIME 250-CHUNKING 250 XRDST at com.sun.mail.smtp.SMTPTransport$Authenticator.authenticate(SMTPTransport.java:826) at com.sun.mail.smtp.SMTPTransport.authenticate(SMTPTransport.java:761) at com.sun.mail.smtp.SMTPTransport.protocolConnect(SMTPTransport.java:685) at javax.mail.Service.connect(Service.java:317) at javax.mail.Service.connect(Service.java:176) at javax.mail.Service.connect(Service.java:125) at javax.mail.Transport.send0(Transport.java:194) at javax.mail.Transport.send(Transport.java:124) at org.cdc.eipo.bean.investorsetup.EmailController.main(EmailController.java:59) ``` any help much appreciated
