Our site has been edicted to Microsoft Exchange server with a Barracuda spam filter. There are numerous difficulties, one of which is spam not being filtered and non-spam being so filtered (significant increase in mission critical false positives). At present, the administrative 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.
