    Java SMTP Client and Outlook unique behaviour


      I have written a simple Java client to send a mail with an attachment to a mail address. Its a normal Java SMTP client with multi part file attachment.

      There is a unique behavior happening which is eating my head for some time now. The issue here is that when i try to send an attachment from my Outlook the message is being delivered to the recipient successfully in recipients inbox. But when i send the same attachment through my standalone Java client its not getting delivered to the recipient(not 100 % sure, spamming maybe).The client is not throwing any exception also so its become very hard as to whats going on as i think the mail is getting delivered but not sure. The recipient email address is on a Linux box so don't know how to access it. please help me on this.

          If your question is related to your Java code you would have to post it.

          If it isn't it is off topic.

              please help me on this.
              What I do is write (or find) a email server that lets me see the raw form of the email.
              Then send from both clients and compare the differences.
