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. <br />
1. How can we stop the mail. Is it on the sender server or on the reciepient server that causing this issue. <br />
2. Why this happened when sending out the large file.<br />
<br />
Thanks.

How can a reciepient stop multiple copy of mail from sender who send it with large attatchment

Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. A MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol (SMTP). The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.
