[Dovecot] Filesystem requirements
What are the filesystem requirements for dovecot - for example I see some people are running with atime updates switched off (as I intend to do so myself), so presumably dovecot has no need of an accurate atime implementation.
How about directory atime? ctime/mtime etc?
I'm intending to run on a linux box using local disk, so am currently considering using reiserfs (3.6) with noatime, nodiratime options since that appeared to work with good performance on the quick benchmark test I tried. I do not have a particularly high opinion of reiserfs reliability, but it normally appears to fail in a all-or-nothing way (ie filesystem unusable) rather than some files going corrupt or missing, so I can work round that with a backup regime.

Only place where atime is used is when listing mboxes. If atime < mtime, the mailbox is returned with \Marked flag. It might be of a small optimization for some clients, but not very important.
ctime is checked with dotlocks, but mtime is as well.
mtime is used in a lot of places and it should be accurate. For both directories and files.
