Re: duplicate mailing problem

I am curious as to your sendmail settings (aliases|virtusertable)
for <[email protected]>.  If the bounce came to this address,
why would it redirect into the list itself?  I also see an address
of list-onwer instead of list-owner in the original headers. Clue?

If wwbnews is a moderated list, I do not understand how a message
could have been distributed without credentials.  If the owner
address is properly configured, I do not understand how the list
would recieve the message.

It looks like your end user is subscribed with an address that is
being forwarded (or held for pick up with DomainPOP similar to
fetchmail) which bounced wwbnews to wwbinfo.  Also confusing, why
would wwbinfo redirect into wwbnews?  This also leads back to the
moderator question.
