Hi John,
Very interesting article. I wasn't aware of that issue, but the fix
doesn't look that difficult and they make a point of saying that its a
"non-destructive" fix, so you don't have to worry about the store or any
custom Exchange settings.

Interesting read:
In some scenarios, the sink bindings may exist in the Exchange
2000 Server metabase but the sink is not properly registered in the
registry. When this occurs, the SMTP protocol does not create the sink
when it tries to process the "MAIL FROM" command. As a result Exchange
2000 Server drops the connection, and the outgoing mail is not
processed.
This issue may occur when a third party program, for example GFI
Mail Essentials, is installed and then incorrectly or incompletely
removed. GFI Mail Essentials contains an add-on named Mail Security.
Mail Security installs an outbound SMTP sink that verifies the validity
of the sender address. If improperly removed, the sink may remain
although the sink is no longer correctly registered. When the "MAIL
FROM" command is initiated by Exchange 2000 Server, the sink fails and
Exchange 2000 Server drops the connection.
