[Dovecot] deliver is ignoring mail_access_groups
by Peter 17 Nov '09

17 Nov '09

Ubuntu 8.04LTS Dovecot 1.2.6 Postfix 2.5.1 I'm using dovecot imap/deliver in an environment where I don't want users with shell access to reach their mail folders (partly to do with IMAP ACLs requiring open group permissions and partly to do with not wanting users to mess their mail folders / sieve configs up). I specifically don't want to switch to a "single dovecot user" style installation. Current config: mail_location = maildir:/home/mail/%d/%n/Maildir mail_privileged_group = mail mail_access_groups = maildir drwxrws--- 3 nobody maildir 21 2009-11-15 10:52 /home/mail drwxrws--- 4 nobody adomain.com 30 2009-11-15 12:12 /home/mail/adomain.com/ drwxrws--- 3 auser adomain.com 20 2009-11-15 10:52 /home/mail/adomain.com/auser drwxrws--- 3 auser adomain.com 20 2009-11-15 10:52 /home/mail/adomain.com/auser/Maildir And so on... As expected IMAP and Managesieve work perfectly, but deliver fails: Nov 15 12:48:26 s15364807 dovecot: deliver(auser(a)adomain.com): sieve: stat(/home/mail/adomain.com/auser/.dovecot.sieve) failed: Permission denied (using global script path in stead) Nov 15 12:28:06 s15364807 dovecot: deliver(auser(a)adomain.com): stat(/home/mail/adomain.com/auser/Maildir) failed: Permission denied Nov 15 12:28:06 s15364807 dovecot: deliver(auser(a)adomain.com): stat(/home/mail/adomain.com/auser/Maildir/tmp) failed: Permission denied (euid=1002(auser) egid=1001(adomain.com) missing +x perm: /home/mail) Nov 15 12:28:06 s15364807 dovecot: deliver(auser(a)adomain.com): msgid=<20091115122806.79A0F80034F(a)servername.com>: save failed to INBOX: Internal error occurred. Refer to server log for more information. [2009-11-15 12:28:06] Opening the permissions on /home/mail (6771) allows deliver to succeed suggesting that mail_access_groups is being ignored by deliver. As a work-around I can set /home/mail to 6771 but this is not ideal as anyone somehow guessing the directory structure could access mail of another user in the same group regardless of IMAP acl settings. Yes, I can severely obfuscate it but it's not secure. I've spent about half a day trying to figure this out, I'm assuming at this point that either I'm missing something obvious or something else is wrong. Any ideas? Peter.

[Dovecot] read() failed with subscription file
by david＠davidwbrown.name 16 Nov '09

16 Nov '09

Hello Dovecot folks, I have Dovecot running reasonably well against my Postfix SMPTd. All mail is stored in Maildir format only. In my Thunderbird client I can see the Inbox, Trash and Sent folders in the Thunderbird pane but no other directories. I have very many Maildir format directories under my Inbox directory but I cannot see them in the Thunderbird client. I have the Dovecot info and debug log runnning with the solitary error message being displayed in the log when ever I access the Thunderbird client folders pane as stated below. Particulars follow and please advise, David. OS: CentOS 5.2 Postfix: 2.3.3 Dovecot: 1.2 Dovecot log: dovecot: IMAP(user): read() failed with subscription file /home/user/Maildir/subscriptions: Is a directory

[Dovecot] v1.2.7 released
by Timo Sirainen 14 Nov '09

14 Nov '09

http://dovecot.org/releases/1.2/dovecot-1.2.7.tar.gz http://dovecot.org/releases/1.2/dovecot-1.2.7.tar.gz.sig * IMAP: IDLE now sends "Still here" notifications to same user's connections at the same time. This hopefully reduces power usage of some mobile clients that use multiple IDLEing connections. * IMAP: If imap_capability is set, show it in the login banner. + IMAP: Implemented SORT=DISPLAY extension. - Login process creation could have sometimes failed with epoll_ctl() errors or without epoll probably some other strange things could have happened. - Maildir: Fixed some performance issues - Maildir: Fixed crash when using a lot of keywords. - Several fixes to QRESYNC extension and modseq handling - mbox: Make sure failed saves get rolled back with NFS. - dbox: Several fixes.
