Search the FAQ for "performance".  Do all such spam/virus/DNS/etc... 
checking up front, and run a second copy of your MTA with all these 
checks disabled.  Have Mailman deliver to the second copy of the MTA, 
because you will have already done all this stuff on input.

There's no sense running the same message through SpamAssassin (or 
whatever) thousands of times, if you can do it once on input and then 
never again.
