I didn't know that mail_nfs_index=yes resulted in a forced chown.
How come that's necessary with NFS but not on local disks?
It's used to flush NFS attribute cache. Enabling it allows you to use

Im experiencing write activity thats somewhat different from my previous
qmail/courier-imap/Maildir setup.
This more outspoken in v.1.1.x than v1.0.x (Im using Maildir).

You could truss the hanging process to see what it's doing.
