After many years of hassle free use from our email system we are now getting
a rather odd disconnect as shown below.

What is frustrating is that is is not occurring every single time, some
emails from this domain pass through with no delay, other times it drops the
connection and the sending server queues it and tries again.
There are two mail servers that send to clients on this system that are
having the issue.
Both of the servers are running Mail Marshal (if that's any help!)
I have done some research on the "lost connection after Data" and many
articles refer to loss of network connectivity which we have tested and is
not the issue. Others refer to incorrect, or lowering the MTU of either NIC
or Router (have confirmed this is also not the issue.
I would be interested to know if anyone else has had a problem like this.
