Hi
Sounds like you know what you are doing!
- can I assume you have given some thought to tuning your file system which handles the spool files?
The server uses xfs for maildir partition and so on, it uses noatime,nodiratime,nobarrier,logbufs=8.
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
