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 ⟶ Connection Rules.
- Double-click the Maximum Mail Size Rule to edit it.
- Find the Email Size Condition, and click
.
- Choose a new limit from the Condition Value dropdown.
