[Dovecot] Feature request - umask for index files

[Marc Perkel]

I'd like a separate feature for setting umask for index and cache files 
differently from email files.

The reason is that I'm putting indexes in a separate location and I need 
group create rights in directories. Otherwise what happens is that the 
first user creates the directories, but the second user for the domain 
that has a different UID gets an error.

default_mail_env = 
mbox:/vhome/%d/home/%n:INBOX=/vhome/%d/home/%n/INBOX:INDEX=/nobackup/imap-index/%d/%n
