Dear all I have been sending mails from exchange server without any problem. However, mails are bouncing back to the senders with the following error message. I found that mails were going to the same domain if sending it without an attachment. It was not reaching them with attachment. I appreciate you all if any one helps me out to fix this problem. bshankar_17@xxxxxxxx on 4/22/2004 10:48 AM A configuration error in the e-mail system caused the message to bounce between two servers or to be forwarded between two recipients.
