[Courier-imap] imapd: Failed to create cache file: maildirwatch and FAM notification error

[PICCORO M. L. <mck...@gm...>]

Hi all guys.. as all well know i am on a courier cruzade and found an
interesting note about this..  of course this only apply on 1.0.14 and
lower older releases, 1.0.16+ dont use FAM anymore..

i noted that on faq it limits to said "its not running"
https://www.courier-mta.org/FAQ.html#fam but must also said: every time
restarted the courier services, if I don't restart the FAM services the
error occurs, so in addition to all of that you must also have to restart
the FAM service. similar is happened with fs notification error on
thunderbird, if you already has fam installed. cos unless gamin, fam is a
service, gamin is per request of users.

important note about FAM vs GAMIN: because GAMIN can't act on virtual
accounts as it doesn't take correctly the lock on the maildir, because the
imapmaildirlock() function in imap/imapscanclient.c tries to allocate a
maildirwatch, which unconditionally calls the monitoring functions in the
home of the owner..

then GAMIN is great only if you have system accounts.. but not if you have
virtual accounts. it seems GAMIN does not suffers from this problem.
