I have a very strange DL expansion problem.
I have a DL that breaks out into many smaller DLs. Some of these DLs contain
the same users.
When I send a message to the top-level DL from Outlook, everyone gets one
copy of the message.
If the message is submitted to the top-level DL from an Internet address,
people who are on the sub-DLs get multiple copies (one for each sub-DL that
they are a member of).
Has anyone else seen this happen?
