[Dovecot] File permissions used for automatically created mailbox

[Frerich Raabe]

Hi,

I'm running Dovecot 2.1.12 on FreeBSD (quite successfully so, thanks for 
this nice piece of software!). One thing which is slightly annoying 
though is that automatically created mailboxes (I have 
lda_mailbox_autocreate set) don't have the file permissions I'd like 
them to have.

I'm using a vmail-based system, i.e. all mail is owned by vmail:vmail; 
another member of the vmail group is called 'backup', which has read 
access to all mail in order to create backups. All mail is stored 
beneath /home/vmail, e.g. /home/vmail/frerich/Maildir

Right now, newly created mailbox directories (e.g. /home/vmail/bob) have 
0700 permissions, but I'd like to have 0750 for all directories and 0640 
for all files so that all files and directories are group-readable for 
backup purposes.

Does anybody know whether this is configurable somehow?

Right now, my workaround consists running this cron script every night:

   #!/bin/sh
   chown -R vmail:vmail /home/vmail/
   find /home/vmail/ -type d -print0 | xargs -0 chmod 0750
   find /home/vmail/ -type f -print0 | xargs -0 chmod 0640
