I guess you have read around a little on XFS + maildir?  There was some 
discussion a while back that showed it could sometimes get a little slow 
without some tweaking - I think the logbugs param you used was mentioned 
as the solution?  Since you are IO constrainted did you try some 
benchmarks on other filesystems?

Good luck
