This is wandering off-topic for the toasters list, I'm afraid; if anyone wants to discuss MTA choices more, do please feel free to drop me a note off-list. What can be said here with relevance is that there are some of us who adore using NetApps as the heart of big mail farms with Maildirs as the enabling data structure. If I'm remembering aright, there was a tasty paper a few years back about some large ISP (Earthlink, maybe?) who took this approach and came away happy.
We're currently using an F760 mounted onto 20 servers for our mail system. We use Courier (POP3) for the 10 reader boxes, and Exim4 for the 10 MTA boxes, obviously using maildir over NFS.
This setup is merrily handling around 5 million inbound emails a week. We're very happy with maildirs on a netapp.
