Assuming you're already running a local caching server for your mail 
system...

Based on the spamhaus fee structure (# of e-mail accounts), our policy 
is to allow spamhaus to block queries from our public resolvers if they 
choose.  The spamhaus folks certainly deserve compensation for their 
efforts, so customers that need such volume should do so from their own 
IP and pay a fee.  While I believe it might be mutually beneficial for 
spamhaus to offer some sort of a recursive DNS provider/ISP fee 
structure, I can see where enforcement would be a problem.  The 
resolution of that particular problem belongs to spamhaus and their 
individual users/customers.
