Hi Karthik,

For your requirement, I assume that you are sending an Outbound email using some smart shape like send mail or some utility like sendsimpleemail. If you are doing so, then you need to handle explicitly by following the steps:

1. Find out the activity which actually formulates the mail e.g., SendEmailNotification for SendSimpleEmail and capture the required values like To, CC,BCC,body etc.

2. Use some java code for creating an eml file and place it under the desired path as follows:

  Message message = new MimeMessage(Session.getInstance(System.getProperties()));
        message.setFrom(new InternetAddress(from));
        message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(to));
        message.setSubject(subject);
        // create the message part 
        MimeBodyPart content = new MimeBodyPart();
        // fill message
        content.setText(body);
        Multipart multipart = new MimeMultipart();
        multipart.addBodyPart(content);
        // add attachments
        for(File file : attachments) {
            MimeBodyPart attachment = new MimeBodyPart();
            DataSource source = new FileDataSource(file);
            attachment.setDataHandler(new DataHandler(source));
            attachment.setFileName(file.getName());
            multipart.addBodyPart(attachment);
        }
        // integration
        message.setContent(multipart);
        // store file
        message.writeTo(new FileOutputStream(new File("c:/mail.eml")));

Thanks,

Praveen.
