title: Java mail works in an internal mail server but other one has issues
body: <p>Sending mail with attachment works using a specific internal mail server, but not with another mail server.</p>
  
  <p>In the actual Production environment , it uses a different mail server, Currently emails are getting send without attachments using this mail server.</p>
  
  <p>But when I send email with attachment using this mail server, it completes the Transport.send ()   , I am trying to print the stack trace of any exception.  but it does not print any exceptions...</p>
  
  <p>Looks like no exception occured but no mail also got send.</p>
  
  <p>Can someone please help...</p>
  
  <p>Thanks.
