One other solution you may want to look into is Microsoft's own Forefront for Exchange.  I won't go into details but it can utilize more than one AV scan engine (I think 6 of the biggest are built in) as well as do content and file filtering between your users with (in Exchange terms) relatively small additional resource usage.  I used to use McAfee Groupshield for Exchange but found that the overhead was higher, had only one (McAfee) AV engine, and similar licensing fees and features.  After a long term trial I switched. Any way you look at it, you will want a AV/Anti-Spam solution for your Exchange server. 

Please note that basic anti-spam support is built-in to Exchange 2007 and 2010 via a mechanism very similar (read - near copy of) to SpamAssasin with sender confidence level (SCL) blocking and DNS RBL support.
