It's used for creating dovecot-acl-list. Hmm. Looks like there are now
two places where Dovecot takes permissions from: dovecot-shared file and
the directory where it exists. If you set g+s to the dir too this error
goes away. I'll have to think a bit more what I'll do about this. Maybe
dovecot-shared file just could go away and only the dir permissions
would be used.
That reminds me, I do think I put dovecot-shared in that directory just to
satisfy 1.1.
The group owner on /egr/mail/shared/decs/ is the group I am using to
restrict entry into
the directory (it is mode 770) so all of the users using folders inside are
part of the
group, so I'm not sure why the fchown would fail?
Also just a note (if I remember correctly) the existance of dovecot-shared
causes
dovecot+acl to treat the folder flags as private unless the code is
modified (I still use
that hack locally) so its not just the permissions of an object (presently
dovecot-shared)
that have an affect. Its seems like this is alot of functionality to load
onto just the
existance and permissions of a file :)
I did set g+s on /egr/mail/shared/decs/ and relogged in with thunderbird
but got the
error right away:

Lately I have been getting:

Right now I have /egr/mail/shared/decs/ unwritable to users. Some of these
errors still happen
when the directory is writable, but I am also concerned if it will cause
these temp files to
be renamed to dovecot-acl-list, which I assume would conflict with other
users if created by
one user.
Uhh, forget that part about being read only. I forgot it needs write so my
shared deliver script
can create new mailboxes.
Should I worry about these errors? Does it impair caching of folder lists or
something?
Thanks.
