I have 3 imap servers - each can run their own bayes, however I would
like everyone to have the same filtering level and share the same
I have been using a single mailbox that all the users can send to,
then " I " have been doing the physical drop into the correct bayes
mailbox. -- it works. But I thought that was a crazy work around, and
that I just had not set it up correctly.
So using a transport map to deliver local with out filter isn't the
