That is almost precisely our current configuration (except that the inbound servers are ~450MHz Pentium-equivalent!). I actually refuse any non-AUTH traffic on the primary server, since it has never been an MX record. I can't use greylisting because too many people here get all freaked out if a message doesn't appear instantly in their inbox. :(
I'm going to rush some other servers in place for the inbound traffic and try using Apache::Qpsmtpd (though I didn't have any luck getting it to work with Apache 2.2, so I'll have to build 2.0 and mod_perl from scratch)...
