Reject oversized emails
EMS accepts emails up to
50Mb inbound or outbound. Should your mail server (Domain Route) not accept this size of message, you can reject the message at the point of SMTP connection. This will make the connecting server create an NDR for the sender.
To change the 50mb limit:
- visit your USS Dashboard and click Products ⟶ Email Security ⟶ Message Rules.
- Double-click the Large Files Rule to edit it.
- Find the Email Size Condition, and click .
- Choose a new limit from the Condition Value dropdown.
