Typically this is due to a broken MTA at one of the MXes you are
delivering to which is using the wrong response code for "mailbox full"
or some similar soft error.

Read your MTA logs. Carefully.
Get several copies of those messages (with full headers) from several
different people and analyse their Received: headers.
Determine from the above exactly where the problem is. and whose
responsibility it is.
