Secure Exchange takes IMF to a full fledged Spam product. It allows you to create policies and whitelists to make IMF more managable.(from product site)SecurExchange - IMF extends the IMF by:
Allowing any number of thresholds to be defined with different actions for each threshold range
For instance, a SCL rating of 4-6 can be assigned "Quarantine", while a SCL rating of 7-9 could be assigned "Delete"
Providing additional actions available to a triggered message. Additional actions like "reroute", "move to any sub folder", "copy to user", "send a message", and others may be assigned. Moving a message to any subfolder does not require Outlook 2003.
Allowing different thresholds and corresponding actions amongst different user groups.
For instance in a school environment, the "staff" group may have messages quarantined for a SCL range, while the "students" group would have those messages deleted.
Automatically or manually allow business partner's messages to bypass Exchange's IMF through SecurExchange's Friendly Domain capability, minimizing false positives generated by the IMF
Creating Safe Sender's lists to prevent Exchange's IMF from archiving or deleting messages on the SMTP gateway / frontend server that exceed the gateway 's IMF threshold.
