Exchange 2007, Anti-Spam on Legacy Server MBX’s?   

Hi,

We’re setting up Anti-Spam functionality on our Exchange 2007 system.  
We also have an Exchange 2003 system in our organization.  
All email to both systems is coming through our Edge server.  
We only want our test user mailboxes to have anti-spam functions applied.  
We’re using the -AntiSpamBypassEnabled $true property to prevent users from 
getting anti-spam functions applied.  But, the -AntiSpamBypassEnabled $true 
property does not work on legacy mailboxes.  

Do MBX’s on Legacy Exchange Servers get anti-spam filters applied from the 
2007 system?  If yes, is there a way to prevent that from happening?

Thanks,
Steve

Re: Exchange 2007, Anti-Spam on Legacy Server MBX’s?   

- Yes, mail received by Exchange 2007 transport servers will be subjected to 
antispam agents.
- If you're using the same namespace, there's no easy way to separate 
inbound mail and process differently, except to route all inbound through 
Exchange 2003 server.

If using different namespaces:
- Create separate Receive Connector with antispam disabled (using transport 
permissions) and point external MX record to it
- Route inbound mail for the Exchange 2003 namespace directly to an Exchange 
2003 server
