Hello, exchange mail user send mail out to a distribution list with a 14MB attatchment file. She has been getting the undeliverable messages in her inbox constantly. I understand that some of reciepient server probably denied the mail delivery and send back the error. The issue is the one who can recieve the mail. They recieve multiple copy in their inbox and it's taking up e-mail space.
1. How can we stop the mail. Is it on the sender server or on the reciepient server that causing this issue.
2. Why this happened when sending out the large file.
