[Dovecot] missing +r perm:
This is probably a really simple issue but I am not sure how to tackle it.
sudo dovecot -n: http://pastie.org/2179100
The error message in mail.log: http://pastie.org/2179032
Dovecot.conf says: mail_privileged_group: mail
I thought of added the user dovecot to the group mail in hopes of
solving the permissions problem, but it didn't seem to make a
difference.
Any ideas?

What are the permissions of that file? Who is dovecot running as? Can the user dovecot is running as read that file?

The permissions are: -rw------- 1 root root 7609 2011-07-05 16:06 /home/dlambert/Maildir/cur/msg.COmK:2,ST
The same as another mail machine we have up (making a transition)
I'm not sure who to find out who dovecot is running as: -rwxr-xr-x 1 root root 217240 2011-06-07 00:03 /usr/sbin/dovecot root maybe?
Thanks so far

You are accessing the maildir structure using UID 1002 but the directory is owned by UID 1. Needs to be fixed on either side...
Please visit these links and have a look at the quote below:
http://wiki.dovecot.org/PasswordDatabase/PAM http://wiki.dovecot.org/AuthDatabase/Passwd
[...] This uses the UID and GID fields from passwd, but home directory is overridden. Also the default mail_location setting is overridden.

Should read UID 0. Shame on me - more coffee required...
Alright, I think I understand. By fixing the other side do you mean I could add mail_uid=0 and mail_gid=0 in dovecot.conf? to match the current mails permissions. We are migrating a server over and we ran into this snag when transferring Maildirs over

IMHO it appears perfectly right to have them share a virtual/generic UID unless you see a special need to separate them all (for an ultra-secure setup FWIW)… Several paths are available. Either return same ID/GID via the user query or set it to a static value if acceptable.
