[Dovecot] Cannot authenticate with new Red Hat/Fedora SHA512
by John Cooper 01 Feb '11

01 Feb '11

RHEL6 and Fedora 14 use an improved password algorithm of SHA512 on a brand new install of the OS (:$6$ in shadow file). cat /etc/shadow user1:$6$<salt>$<password>:15006:0:99999:7::: I cannot get dovecot to authenticate. I've search for a way to change the default algorithm in dovecot and found you should use CRYPT but I don't know what to put in the /etc/dovecot/dovecot.conf or /etc/dovecot/conf.d/* Can this be done or do you need to use an alternate password file with MD5? Thanks, John.

[Dovecot] cgroup support
by Andreas Pelme 01 Feb '11

01 Feb '11

Hi, I am setting up a system that enforces cgroup restrictions when a user logs in via SSH, and for all the services that are run by a particular user. I am also running dovecot to give users IMAP/POP access to their mailboxes. However, to be part of a cgroup, PIDs must be explicitly added to the cgroup tasks file. So for now, all my processes are run with resource restrictions, except for Dovecot processes. It would be really cool if dovecots child/worker processes could be added the a cgroup in addition to the usual setuid/chroot protections that already exists. Adding a process to a cgroup is a matter of writing the PID to the correct cgroup tasks file. If this were implemented as an extra field in userdb, it could be very powerful, and allow for all kinds of resource management/accounting of dovecot processes. This would obviously not be cross-platform, since cgroups are a feature of the Linux kernel. Would that be a problem? Is support for cgroups something that could be considered for dovecot at all? Are there other ways to put dovecot processes in cgroups? I do not really have a patch or a plan for how everything would work out in detail. If this would be useful for dovecot, I would be happy to start hacking on a patch. Cheers Andreas

[Dovecot] Permissions issues after dovecot reload
by Matt Rude 01 Feb '11

01 Feb '11

Hello, Today while looking at a different issue (one user couldn't retrieve mail; DNS issue) I set 'mail_debug=yes' then ran `dovecot reload` on our mail server. After running the reload, dovecot started complaning about permission issues with the dict file, and preceded to try to kill it's self. The self reload didn't seem to work, and since this is a production system, I was forced to restart the dovecot service. After the restart of the service, everything seemed to go back to normal. Dovecot is currently working as expected, no other permission errors in the logs. Dovecot Version: 2.0.9 (3582271a897e) running on Fedora 14 running with a mySQL setup including dict tables (quota, expire). The virtual user's mail has a local user and group id of 1000.

[Dovecot] disable_plaintext_auth = no ignored by dovecot in Ubuntu 10.04
by David Mattox 31 Jan '11

31 Jan '11

Help!! I have been trying to get Dovecot configured to allow plaintext auth with no success. After some testing with the mail system I discovered the >dovecot -a commant to dump the config file values from the program. Gee, changing the value of disable_plaintext_auth had no effect on what the program reported this value to be! To eliminate possible errors caused by other config file entries I finally restored the /etc/dovecot/dovecot.conf file that was created by installing the package. I then changed the one line to uncomment disable_plaintext_auth and set it equal to no. restart the box and execute dovecot -a The value is still set to the default value of yes... Help! What is happening and how to I get this system to allow plain text auth without TLS? I did also try setting different ports for imap, imaps, pop3, pop3s inside the seperate protocol blocks with no effect. Below you will find a partial of the config file. Below that you will find the output of >dovecot -a and >dovecot -n Thank you in advance for any help with this problem.

[Dovecot] Particular user post-login hang
by Henry C. 31 Jan '11

31 Jan '11

Greets, I'm using dovecot 2.0.9 (also tried rolling back to 2.0.8 which does the same - the output below is from 2.0.8), and this problem is imap specific. The following is a recurring problem with a specific user - as far as we can tell, other users are working just fine (there are thousands); but I bet there are others. In a nutshell: User authenticates OK, then the imap process hangs. It's almost as if something in the user's inbox is causing the problem, since if I clear all emails (and cache), then things work fine. The user will then receive emails OK for some random period (maybe a few days) and be able to read/write OK via imap, and the problem will re-occur. The debug output shows nothing untoward: auth: Debug: auth client connected (pid=20774) auth: Debug: client in: AUTH 1 PLAIN service=imap secured lip=127.0.0.1 rip=127.0.0.1 lport=144 rport=41641 resp=<hidden> auth: Debug: shadow(username,127.0.0.1): lookup auth: Debug: client out: OK 1 user=username auth: Debug: master in: REQUEST 1938161665 20774 1 238230058d076a9af1cd4405244d33ba auth: Debug: passwd(username,127.0.0.1): lookup auth: Debug: master out: USER 1938161665 username system_groups_user=username uid=17286 gid=300 home=/home/mailusers/username imap-login: Info: Login: user=<username>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=20775, secured imap(username): Debug: Effective uid=17286, gid=300, home=/home/mailusers/username imap(username): Debug: fs: root=/home/mailusers/username/., index=, control=, inbox=/var/mail/username Rawlog looks good: IN: A002 CAPABILITY A003 NAMESPACE C64 EXAMINE "" A002 STATUS "INBOX" (MESSAGES UNSEEN RECENT) A003 SELECT "INBOX" A004 EXPUNGE A005 SELECT "INBOX" A006 EXPUNGE A007 UID SEARCH UNSEEN A008 UID FETCH 2533:2588 (FLAGS BODY.PEEK[HEADER.FIELDS (RECEIVED)]) OUT: ... * 15 FETCH (UID 2536 FLAGS () BODY[HEADER.FIELDS (RECEIVED)] {944} ... * 67 FETCH (UID 2588 FLAGS () BODY[HEADER.FIELDS (RECEIVED)] {945} ...

[Dovecot] dovecot can't see mail that is there
by Joachim Ferreira 31 Jan '11

31 Jan '11

Hi list, I've yet to figure out what's the issue with my installation, why I can't see the mails that are definitely there. I've updated with last package: dovecot-2.0.9-1.fc14.x86_64.rpm and performed the following test: 1) send a simple 2 lines test mail from "root" to user "testdvct" with alpine 2) login under "testdvct" + run alpine + list (only list, not read) the mail: +------------------------------ Alpine Output --------------------------------------+ | ALPINE 2.02(1266) MESSAGE INDEX Folder: INBOX Message 1 of 1 NEW | | | | + N 1 17:43 root (881) | +--------------------------------------------------------------------------- --------+ so it tells me I've got one mail from root 3) I issue the command: "strace -o strace-dovecot.txt -p 2218" where 2218 is the /usr/sbin/dovecot PID 4) telnet into pop3: # telnet localhost pop3 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. +OK Dovecot ready. user testdvct +OK pass <my-password> +OK Logged in. list +OK 0 messages: . quit +OK Logging out. Connection closed by foreign host. 5) kill strace Still no joy! Is there anything else I can do to debug this issue?

Now I've been struggling for two days and I haven't got my mail working yet. I have Fedora 14 with sendmail. Some application on the same machine send mail to an account on the same machine (hence all is confined to one machine) and I want to retrieve it from a laptop on the same LAN via Outlook. If I login into the account and check the mail with the alpine (ex pine) client, I see that there are 10 mails. When I "telnet localhost pop3" and login into the account, the "list" command says there are 0 mails. Various suggestions found on the internet for slightly different configuration did not help. All the help will be very much appreciated.

[Dovecot] Duplicate messages when moving message to inbox
by Ron Garret 31 Jan '11

31 Jan '11

Hello, I am encountering a strange problem but I'm not sure if it's a dovecot problem or a Mac Mail problem. The symptom is that if I move a message from a folder into my inbox the message ends up showing up as a duplicate in Mac Mail. On the server it's still just one message. This ONLY happens when I move a message IN to the inbox. It does not happen when I move a message out of my inbox into a folder, or when I move a message between folders. I can force a sync on Mac Mail and the duplicate is still there. If however I quit Mac Mail and start it up again, the duplicate disappears. I can move one of the duplicated messages out of my inbox into a folder and then back into my inbox repeatedly and end up with (apparently) an arbitrary number of copies of the same message. On the server, though, there is still only one file. Surely I'm not the first person to have encountered this behavior? Does anyone happen to know if this is a dovecot bug or a Mac Mail bug (or, hopefully, a configuration problem)? Thanks, rg
