Java Programming

Hi

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.

Thanks
