We are having difficulty receiving mail from only certain individuals, 2 or 3 that we know of. Our mail comes in to a company that handles our domain. They point the mx record to our MS Exchange server that is set to receive all mail addressed to our domain with no size limits set.
------------
Subject: Undeliverable Mail
The message these people get is "Delivery failed 20 attempts:"
------------
I do not see any reference to it being rejected by any server.
I've been told by the people managing our domain that it has to be our Exchange server that is "too busy". Funny that every other piece of mail comes in fine including tons of junk mail. There are only 4 PCs in the network. What would make mail from just a couple individuals fail to get in. The emails in question were not large, no attachments, just text.
Can anyone give me an idea of where the problem might be?
