According to this article:
When creating new files inside a mailbox, Dovecot copies the
read/write permissions from the mailbox's directory.
I'm not seeing this. Here is what I'm seeing:
andrewsav@hroon-precis:~$ dovecot --version

The mail directory has rw for the group and the individual files in the new directory for some reason do NOT have rw. Because of this they can't be accessed by people/processes they are desired to be accessed. What am I missing?
I'm running ubuntu 12.04LTS
Update 1
To give a bit of background: I've been running postfix+dovecot for quite some time now. It was installed with small deviations according to this document. Normally mailboxes are not accessed locally, the I accessed via POP/IMAP by remote client.
However I find it useful to run mutt occasionally on the server. I can do it alright if I run it as
sudo mutt -f /var/mail/vhosts/myhost.com/andrews
however I wanted to be able to run it without sudo, and that's where the trouble started. I added myslef into vmail group and I added the following lines into .muttrc:
set spoolfile = '/var/mail/vhosts/myhost.com/andrews/'
alternates myhost.com
set reverse_name = yes
set from = 'andrews@myhost.com'
But this does not work unless I explicitly do chmod g+rw on new and cur. And it works only until new mail arrived, because the new mail does not have that rw.
Is there anyway I can solve this?
Update 2
After discussing this issue with NickW in chat, we came to the conclusion that it's actually Postfix that are writing these files, and not Dovecot. The LDA is most likely Postfix virtual. Here is Postfix configuration.

I searched Postfix documentation and I was not able to find a way to specify permissions to Postfix for newly created mail message files inside a mailbox.
My thinking is that it could be impossible, and then there must be another way of setting up mutt so that it can access the maildirs without need to do sudo/be root.
Any hints are appreciated.
Answer
I'm answering here instead commenting , so I can format properly.
Since you have dovecot, you should already have lda installed (its in dovecot-core ).
Add this to /etc/postfix/master.cf:
dovecot unix - n n - - pipe
flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/deliver -d ${recipient}
Add this to /etc/postfix/main.cf:
virtual_transport = dovecot
dovecot_destination_recipient_limit = 1
Change /etc/dovecot/conf.d/15-lda.conf:
protocol lda {
postmaster_address = postmaster@example.com
log_path = /var/log/dovecot-deliver
info_log_path = /var/log/dovecot-deliver
}
(though pretty much optional that 3 line between {} )postmaster_address is the from address for the bounced mail
Change /etc/dovecot/conf.d/10-master.conf:
service auth {
...
unix_listener auth-userdb {
mode = 0666
user = vmail
group = vmail
}
...
}
Add all users from /etc/postfix/vmailbox to /etc/postfix/virtual like this:
user1@myhost.com user1@myhost.com
user2@myhost.com user2@myhost.com
... etc
Move the catch-all to /etc/postfix/virtual:
@myhost.com andrews@myhost.com
Change /etc/dovecot/conf.d/15-lda.conf:
lda_mailbox_autocreate = yes
This will auto-create maiboxes that are absent
To keep the discard rules,
Add to main.cf :
mydestination=localhost.localdomain
Add to /etc/postfix/virtual:
info@myhost.com devnull@localhost.localdomain
sales@myhost.com devnull@localhost.localdomain
webmaster@myhost.com devnull@localhost.localdomain
Then to /etc/aliases :
devnull: /dev/null
These lines from /etc/postfix/main.cf are no longer needed and can be removed:
#virtual_mailbox_base = /var/mail/vhosts
#virtual_minimum_uid = 100
#virtual_uid_maps = static:5000
#virtual_gid_maps = static:5000
#transport_maps = hash:/etc/postfix/transport
Run
- newaliases
- postmap /etc/postfix/virtual
- service postfix restart
- service dovecot restart
and lets hope it works.
