Hi !

We are getting this bounce error message from our customers trying to send emails to our newly built C370 Ironport box.

Here is the error message;

"The following message to nilesh.prasad@mitchelkeil.com.fj was undeliverable.

The reason for the problem:

5.3.0 - Other mail system problem 552 - '#5.3.4 message header size exceeds limit'"

Hope is Delivery Satus Notification will help to identify what the problem is about.

Appreciate your kind response on how to fix this issue.

Best Regards,

Ruveni
