[Dovecot] dovecot transaction log permissions

[Jordan Tardif]

So after some problems with NFS and transaction logs getting corrupted. 
Im tyring out storing them localy. via..

mail_location: maildir:~/Maildir:INDEX=/var/dovecot/indexes/%u

the problem is with a large amount of users.. the indexes dir becomes 
huge with this setup. So a change to make this better is...

mail_location: maildir:~/Maildir:INDEX=/var/dovecot/indexes/%d/%n

to seperate the users dir's into domains. What seems to happen is dovecot 
creates the index's folder automaticly and its owned by that user.. eg..

drwx------    3 10651674 2598184   4096 2010-06-02 19:08 domain.com


this makes it so no other user of domain.com can get their transaction 
logs created cause the dir is owned by another user at that domain. Is 
there anyway around this? I see there used to be a umask option but that 
is gone in 1.2.x.
