Up until this past year, Forefront for Exchange anti-spam with Cloudmark was rather reliable. However for the past year, spam has been hitting my environment pretty hard. All engines are up to date, forefront is properly integrated, it does catch a good bit of spam based off Connection, SMTP, and Content filtering. However content filtering and SCL/PCL tagging is just the absolute worst. It only is marking e-mails SCL 0 or SCL 9 no inbetween more and more employees are complaining of blatant spam being marked SCL 0. (only becuase I changed the configuration to stop marking them as SCL -1 so IMF can atleast try to do it's job)
Is it just me or has forefront met it's match, I dont even think Cloudmark is keeping up with this anymore.....Time to start looking for a better solution?
And no...No...rules, hard IP blocks, DNS RBLs...and submitting messages to an identity that's probably not evening monitoring submissions is not going to be a good fix...
SIGH
