Implementation :

To solve the above issue, we should have a application via which the main application should able to post the e-mail.

Below is the implementation of the post email method.

In the class we have to import following java packages.

import javax.mail.Address;

import javax.mail.Message;

import javax.mail.MessagingException;

import javax.mail.PasswordAuthentication;

import javax.mail.Session;

import javax.mail.Transport;

import javax.mail.internet.AddressException;

import javax.mail.internet.InternetAddress;

import javax.mail.internet.MimeMessage;

In the method body we should write the below logic

String stringSMTPHOST = “SmtpHost”;

String stringSMTPPORT = “SmtpPort”;

final String stringUSERSERVER = System.getProperty("SAPSYSTEMNAME").toUpperCase();

String string_AUTO_GENERATED_TEXT = “Auto_Generated_Text”;

Session session = null;

Properties props = new Properties();

       props.put("mail.smtp.host", stringSMTPHOST);

       props.put("mail.smtp.socketFactory.port", stringSMTPPORT);

       session = Session.getInstance(props);

List<Object of Data Structure> list_EmailStruct = “Email Address List”;

Address[] addressesTo = new Address[list_EmailStruc.size()];

Now based on the list of Email Address application need to iterate like below.

for(int i =0; i < list_EmailStruct.size(); i++){

String stringDataSource = "";

String string_EmailID = "getEmailID from the list_EmailStruct";

addressesTo[i] = new InternetAddress(string_EmailID);

String string_subject = "As per the business requirement";

String string_Message = "getMessgaeDetails";

       message.setFrom(new InternetAddress(stringUSERSERVER+"@"+”Domain Name Like example.com”));

       message.setRecipients(Message.RecipientType.TO,addressesTo);

       message.setSubject(string_subject);

       message.setText(string_Message);

try {

      Transport.send(message); // With Help of send method of Transport API , our mail will get post

      } catch (Exception e) {

      e.printStackTrace();

      }

}
