NDR QUESTION - exchange 2010

I am trying to understand the NDR messages setup beforehand by someone else.

I sent 2 test emails from outside the organization, above the set limit for attachments.
The limit is set to 11MB.

I sent a 13MB email and got a NDR from - Mail Delivery System title 'Undelivered Mail Returned to Sender'
I sent a 12MB email and got a NDR from - Postmaster@xxx.com title 'Undeliverable: subjectname'

Can someone explain where the emails are coming from, and how the system is differentiating between the 2 different emails?  Basically, how come one email is from postmaster and other is from mail delivery system.

We would like the postmaster message as it looks better and has explanation.

You need to check all of your limits, because I would expect the same NDR to be returned. I suspect that one of the limits is different. Check Send and Receive Connectors, global settings and also anything else that touches email, such as firewalls, AV software etc.

With a 11mb limit, a 12mb and 13mb file could be handled differently, because the limit is not equal. A 12mb attachment could be 18mb or more as seen by Exchange because of encoding overhead. It depends on the attachment type.

Should all connectors/global settings be set to the same?
Im guessing yes for our environment but  wanted to ask

Yes, the best practise is to have everything the same.
If you want then limit certain traffic types, use transport rules.
