Third party spa filtering - Server wide

[DBJoshua]

Hi,

What third party email spam filtering service will work with cPanel on a SERVER-WIDE basis. That means, no need to create all email addresses in the third party (hosted) sofrware. Create the emails in cPanel, and have all incoming mail (this includes reseller servers, where we can't edit dns zone files for every single domain) scanned and then delivered.

I want to do it this way, as exim / spamassassin are resource hogs and I want to stop wasting cpu cycles on them.

Thank you in advance.
