NFS may be problematic. Dovecot expects a perfectly working NFS setup, which seems to be a bit rare to find. http://wiki.dovecot.org/NFS
Just for the record, dovecot will be access the mail directly on the disks, it will be the LDA's on the postfix instances coming in over NFS. I'm reading the NFS again to make sure I understand the risks
If the LDA is Dovecot deliver, it's the same problem since it also updates index/control files that cause the problems. But if you're using something else that does nothing but write the maildir files, then it's fine.
I'm looking to use the Dovecot LDA so the caches are updated and the filenames are correct, to get good POP3 performance.
I'm looking forward to giving Dovecot a go, but I'll rig up a staging environment first.
Thanks for the encouraging responses everyone.
Best
