Our site has been edicted to Microsoft Exchange server with a Barracuda

authorities (all of whom appear to be management professionals, not
internals nor systems folks) insist on Exchange, allowing open systems
standards compliant end-users to have IMAP service.  Given this, what
are the best server-side spam filters, either hardware or software?
"Best" should be based upon current field-deployed experience and/or
unsolicited external reviews (not vendor-supported "independent" reviews).

Thanks for any information.

Hi Yasha,

   I would like to know the answer too.

   In the mean time, make sure your web pages do not
have "MailTo:" any tags.  If someone wants to eMail you,
make them use a form.  Robots harvest these tags.

   A few of my colleagues in this area would install an
exchange server in a customer's bath tub if allowed.
I tell myself that Exchange is all they know, but sometimes
I wonder if they are making work for themselves.  Exchange
servers require a lot of fussing.  One customer had
one workstation and one Exchange server.  Now that was
make work.
