If multiple dovecot instances are running at the same time and they
all modify the same files. you need to set fuse_disable_pagecache to
true.

Ok, but in my configuration, each mail user is mapped to a single server.
So files are accessed only by a single server at a time.


how about mail delivery ? if you use dovecot deliver a delivery can occur (and rewrite dovecot index/cache) at the same time as a user accesses imap and writes to dovecot index/cache.



kind regards
