Exchange 2000 Email Distribution Group Stopped Working

My Email Distribution list suddenly stopped working.  The mail appears to leave outlook with no errors and then disappears.  If I send email to the 10 groups contained within my distribution group, the mail flows to them.
I have deleted and re-created the distibution list, it did not fix it.
I have changed the distribution group to a "universal" group, that did not fix it.
I have correctly set the permissions.
This is absolutely the most puzzling problem I have ever encountered.  This thing has worked for 3 years, then suddenly...kaput!

This issue can occur if you use global distribution groups in a multidomain forest.You delete the dl and create a new universal distribution group.It should work.

I only have one domain, one forest.  I have deleted the group and re-created it.  It didn't fix the problem.
when a message is not delivered, a delivery report is sent to the distribution group owner, use Exchange System Manager to configure the group to use the Send delivery reports to group owner option or to use the Send delivery reports to message originator option.

To configure Exchange server to send additional reports to the owner of the distribution group, add the following registry entry, and then set the registry entry to a value of 79:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSExchangeTransport\Parameters\DLUnsuppressedMessageTypes.

now you send mail and see what dl owner get?
or else use msg tracking to see where the mail goes?

I am the owner of the DL list.  The mail goes and disappears, there is no delivery report.

Try message tracking.

I get this error:
Event ID  9002
Categorizer encountered a hard error while processing a message.  The function 'ExpandRecipient' called 'HrDoRestrictions' which returned error code '0xc0040557' (Some malformed property of the recipient caused it to be NDRd
). ( m:\transmt\src\cat\sinks\phatcat\cptexpand.cpp@180 )

Event ID  9000
The function 'CPhatCat::HrDoRestrictions' failed for reason 'The sender does not have the permissions required to send this message to it the intended recipients.
' when processing the recipient 'all.hands@mycompany.com' of type 'smtp'.  A DSN has been generated.  

The article link you sent doesn't address this issue, although I followed the steps for the workaround.

By the way, I am not running an expansion server (at least not to my knowledge).  We only have one Exchange 2000 Server on a 2000 Member Server that is on a Windows 2000 Domain controller.  
That article keeps mentioning an expansion server....I don't have one.

By the way, message tracking shows nothing.  This mail just vanishes.
This will definitely solve your problem.

Nope.  That didn't solve the problem either.  I am about to pull my hair out!  What is going on?

Update:  The distribution group allows me to send through it as long as I use outlook as an Exchange Client.  If I use it as a POP3 client, it will not send through the distribution group.  It will not let me send through it using an Outlook Express account either.  
Maybe this is some important clues?

If nobody has an answer I will chalk this up to a complete re-install of Exchange and call this closed.  This is the dangdest thing I have ever seen.
