Not able to send a zip file through javamail

I am trying to send an attachment containing a zip file through javamail. However, while sending it throws an exception as

com.sun.mail.smtp.SMTPSendFailedException: 552-5.7.0 This message was blocked because its content presents a potential 552-5.7.0 security issue.

I added MIME content type as application/zip but facing 

javax.mail.MessagingException: IOException while sending message;
 nested exception is:
 javax.activation.UnsupportedDataTypeException: no object DCH for MIME type 
 application/zip at com.sun.mail.smtp.SMTPTransport.sendMessage(SMTPTransport.java:1167)

Below is my code snippet:

BodyPart messageBodyPart = new MimeBodyPart();
messageBodyPart.setContent(message, "application/zip");
Multipart multipart = new MimeMultipart();
multipart.addBodyPart(messageBodyPart);
File srcFile = new File(System.getProperty("user.dir")+ "/Reports/");
messageBodyPart = new MimeBodyPart();
DataSource source = new FileDataSource(srcFile.getPath()+"/Report.zip");
messageBodyPart.setDataHandler(new DataHandler(source));
messageBodyPart.setFileName("Report.zip");
multipart.addBodyPart(messageBodyPart);
message.setContent(multipart);
Transport.send(message);

When I remove the .zip extension it works fine but not with .zip.

Your code is adding the attachment twice, which I'm sure is not what you want. Replace your code with this:

MimeBodyPart messageBodyPart = new MimeBodyPart();
String srcFile = System.getProperty("user.dir") + "/Reports/Report.zip";
messageBodyPart.attachFile(srcFile, "application/zip", "base64");
multipart.addBodyPart(messageBodyPart);
message.setContent(multipart);
Transport.send(message);
