SYMPTOMS
When Microsoft Exchange 2000 Server generates delivery and non-delivery reports, third-party Message Transfer Agents (MTAs) may discard the reports.



CAUSE
This problem occurs because Exchange 2000 sets the value of the OriginallySpecifiedRecipientNumber argument to 0. Some third-party MTAs discard reports if the OriginallySpecifiedRecipientNumber argument is not set to a value of 1 or greater.
