[Dovecot] cPanel && Dovecot 2.x
by Marc Jauvin 10 Feb '13

10 Feb '13

I would like to know if dovecot 2.0.9+ can work with cPanel. I know there is a template for it in cPanel 11.34.1, but when I tried to switch to 2.0.9 (from 1.2.17), it didn't work. I didn't put too much time to test it since I only have one live system to test it with, and I have many customers hosted on this server and I cannot disrupt the service. Has anyone been able to make this work, and if so, is there anything special to do other than rebuilding the config with "/scripts/builddovecotconf" ? Thanks.

[Dovecot] GSS-SPNEGO with dovecot and Outlook without Samba
by Julian David Rath 10 Feb '13

10 Feb '13

I am trying to configure a dovecot2 IMAP server to inter-operate with a active directory to authenticate users. The users should be able to login without a password on a domain-joined client(Outlook). Is it possible to do this only with kerberos? I don't want to put a crappy winbind on my mailserver... I already configured my server to authenticate via kerberos(GSSAPI), but Outlook does not even try to authenticate using GSSAPI, it rather uses PLAIN. I would appreciate any help, many thanks in advance.

[Dovecot] dsync timeout?
by Micah Anderson 08 Feb '13

08 Feb '13

I'm using dsync for a regular backup. The backup system flocks so that two cannot run at the same time, which is generally a good thing. The problem is that it seems like dsync sometimes goes off into the weeds and never comes back, leaving a process running and doing nothing forever, hogging the lock and causing my backups never to run again. I just finally figured out that was what was causing the backups not to run on this system was this process: root 17836 0.0 0.0 40888 1600 ? S 2012 0:00 ssh -i /root/.ssh/backmaildir_id_rsa backmaildir@arg /usr/bin/dsync -u foobar server yeah, that has been running since 2012 :( root:/tmp# strace -p 17836 Process 17836 attached - interrupt to quit select(8, [4], [], NULL, NULL very exciting... There doesn't seem to be a timeout in dsync, but perhaps there should be? At this point my only option is to write a cronjob that will look for dsync processes that are over a certain amount of time old and then kill them, after I do that I will need to take a shower because that is a very dirty solution :P thanks for any ideas, or help! micah --

[Dovecot] Dovecot-2.1.14 - pop3 processes always hangs forever - a follow-up
by Axel Luttgens 08 Feb '13

08 Feb '13

Suspecting a problem with the "virtual" uids/gids, I've tried with a real user for the mail user: # 2.1.14: /_ETC/dovecot/dovecot.conf # OS: Darwin 12.2.1 x86_64 auth_verbose = yes disable_plaintext_auth = no mail_debug = yes mail_gid = dovemailer mail_location = mbox:~/mboxes:INBOX=~/mboxes/inbox mail_uid = dovemailer passdb { args = /_ETC/dovecot/db.conf driver = sql } ssl = no userdb { driver = prefetch } Of course, the db queries do not return uid/gid pairs anymore. And the pop3 processes now seem to work as expected; connecting for the first time as user1: $ telnet 127.0.0.1 110 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. +OK Dovecot ready. user user1 +OK pass pass1 +OK Logged in. list +OK 0 messages: . quit +OK Logging out. Connection closed by foreign host. Hmmm... Axel

[Dovecot] Dovecot-2.1.14 - pop3 processes always hangs forever
by Axel Luttgens 08 Feb '13

08 Feb '13

Hello, I'm currently experimenting with the 2.1.x series and am facing a behavior I can't explain; I must be doing something wrong and probably miss the obvious... ;-) This is a very basic build on Mac OS X 10.8.2: ./configure --prefix=/_COD/dovecot-2.1.14 --sysconfdir=/_ETC --localstatedir=/_VAR --with-sqlite --with-ldap=yes (Yes, I know, a strange layout, yet very convenient for testing various things here.) Dovecot's configuration is very basic too: # 2.1.14: /_ETC/dovecot/dovecot.conf # OS: Darwin 12.2.1 x86_64 auth_verbose = yes disable_plaintext_auth = no mail_debug = yes mail_location = mbox:~/mboxes:INBOX=~/mboxes/inbox passdb { args = /_ETC/dovecot/db.conf driver = sql } ssl = no userdb { driver = prefetch } It is started from launchd with the -F flag. Two users are defined in the database, user1 (100002/100002) and user2 (100003/100003), with "virtual" uids/gids. Connecting for the first time as user1 through imap: $ telnet 127.0.0.1 143 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE AUTH=PLAIN] Dovecot ready. a login user1 pass1 a OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS THREAD=ORDEREDSUBJECT MULTIAPPEND UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS SPECIAL-USE] Logged in b logout * BYE Logging out b OK Logout completed. Connection closed by foreign host. In mail.log: dovecot[2997]: imap-login: Login: user=<user1>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=3006, secured, session=<EOWWzjbVxQB/AAAB> dovecot[2997]: imap(user1): Debug: Effective uid=100002, gid=100002, home=/_Data/Mailstores/100002 dovecot[2997]: imap(user1): Debug: Home dir not found: /_Data/Mailstores/100002 dovecot[2997]: imap(user1): Debug: fs: root=/_Data/Mailstores/100002/mboxes, index=, control=, inbox=/_Data/Mailstores/100002/mboxes/inbox, alt= dovecot[2997]: imap(user1): Debug: Namespace : /_Data/Mailstores/100002/mboxes doesn't exist yet, using default permissions dovecot[2997]: imap(user1): Debug: Namespace : Using permissions from /_Data/Mailstores/100002/mboxes: mode=0700 gid=-1 dovecot[2997]: imap(user1): Disconnected: Logged out in=8 out=362 While logged in (ie after the login and before the logout), "doveadm who" shows: username # proto (pids) (ips) user1 1 imap (3093) (127.0.0.1) So far, so good. Now, let's connect as user2 for the first time, through pop: $ telnet 127.0.0.1 110 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. +OK Dovecot ready. user user2 +OK pass pass2 and the session hangs forever. This is written in the log: dovecot[2997]: pop3-login: Login: user=<user2>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=3113, secured, session=<GTOlMjfV3gB/AAAB> dovecot[2997]: pop3(user2): Debug: Effective uid=100003, gid=100003, home=/_Data/Mailstores/100003 dovecot[2997]: pop3(user2): Debug: Home dir not found: /_Data/Mailstores/100003 dovecot[2997]: pop3(user2): Debug: fs: root=/_Data/Mailstores/100003/mboxes, index=, control=, inbox=/_Data/Mailstores/100003/mboxes/inbox, alt= dovecot[2997]: pop3(user2): Debug: Namespace : /_Data/Mailstores/100003/mboxes doesn't exist yet, using default permissions dovecot[2997]: pop3(user2): Debug: Namespace : Using permissions from /_Data/Mailstores/100003/mboxes: mode=0700 gid=-1 dovecot[2997]: pop3(user2): Debug: Namespace : /_Data/Mailstores/100003/mboxes/inbox doesn't exist yet, using default permissions dovecot[2997]: pop3(user2): Debug: Namespace : Using permissions from /_Data/Mailstores/100003/mboxes: mode=0700 gid=-1 dovecot[2997]: pop3(user2): Debug: Namespace : /_Data/Mailstores/100003/mboxes/inbox doesn't exist yet, using default permissions dovecot[2997]: pop3(user2): Debug: Namespace : Using permissions from /_Data/Mailstores/100003/mboxes: mode=0700 gid=-1 while "doveadm who" pretends nobody is connected: username # proto (pids) (ips) To get rid of the pop3 process, I have to send it a KILL signal: no other way. But this is noticed by the master process: dovecot[2997]: pop3(user2): Fatal: master: service(pop3): child 3113 killed with signal 9 Note that it is possible to connect afterwards as user2 through imap. On the other hand, trying to connect as user1 or user2 through pop always hangs. TIA, Axel

Hi, I upgraded to version 2.1.1 from version 1.0.7 and I am having issues with postfix and dovecot reading my userdb file.
