[Dovecot] I can't sync with dsync and imapc
by Angel L. Mateo 12 Feb '13

Hello, I am deploying a new dovecot server to replace and old one, both of the with dovecot 2.1.9. Now I want to synchronize imap mailbox from the old to the new one. So, in my new server I run (whith a $ sudo dsync -v -D -o imapc_host="<oldserver>" -o imapc_password="<master password>" -o imapc_features=rfc822.size backup -R -f -u myuser(a)um.es imapc: doveadm(root): Debug: Loading modules from directory: /usr/lib/dovecot/modules doveadm(root): Debug: Module loaded: /usr/lib/dovecot/modules/lib01_acl_plugin.so doveadm(root): Debug: Module loaded: /usr/lib/dovecot/modules/lib02_lazy_expunge_plugin.so doveadm(root): Debug: Module loaded: /usr/lib/dovecot/modules/lib10_quota_plugin.so doveadm(root): Debug: Module loaded: /usr/lib/dovecot/modules/lib20_zlib_plugin.so doveadm(root): Debug: Loading modules from directory: /usr/lib/dovecot/modules/doveadm doveadm(root): Debug: Module loaded: /usr/lib/dovecot/modules/doveadm/lib10_doveadm_acl_plugin.so doveadm(root): Debug: Skipping module doveadm_expire_plugin, because dlopen() failed: /usr/lib/dovecot/modules/doveadm/lib10_doveadm_expire_plugin.so: undefined symbol: expire_set_deinit (this is usually intentional, so just ignore this message) doveadm(root): Debug: Module loaded: /usr/lib/dovecot/modules/doveadm/lib10_doveadm_quota_plugin.so doveadm(root): Debug: Module loaded: /usr/lib/dovecot/modules/doveadm/lib10_doveadm_zlib_plugin.so doveadm(root): Debug: Skipping module doveadm_fts_plugin, because dlopen() failed: /usr/lib/dovecot/modules/doveadm/lib20_doveadm_fts_plugin.so: undefined symbol: fts_backend_rescan (this is usually intentional, so just ignore this message) doveadm(myuser(a)um.es): Debug: Added userdb setting: plugin/quota_rule=*:storage=10G doveadm(myuser(a)um.es): Debug: Effective uid=2012, gid=204, home=/home/buzones/b1/an/myuser doveadm(myuser(a)um.es): Debug: acl: No acl_shared_dict setting -

Hi Timo With the current hg (ed5fa76f0dc7), I get a crash as soon as I append a single message to a dsync replicated mailbox.

[Dovecot] Keyword Flags
by David Woodfall 11 Feb '13

11 Feb '13

I mostly use Mutt to read mail but today I fired up Thunderbird. I have a shell script that looks for new mail, which looks for files in cur/ and new/ ending with the server hostname or a comma. When I fired up TB it seems that all new mail has been given a flag of ,a which I gather means it matches a keyword. My questions are: How did this happen? Did TB do something strange to my mail when it fetched headers? If I change my search parameters to ',[a-z]' will this only catch new mail?

[Dovecot] Disabling auth caching just from one passdb
by Angel L. Mateo 11 Feb '13

11 Feb '13

Hello, I'm using various password databases (one of them is a ldap database, which is the used for users connecting with email clients, and the other with pam, using a pam module integrated with our SSO that is used from our webmail). I would like to disable password caching in my pam database (because 'passwords' provided by our SSO are single use tokens, so caching them has no benefit), but not in the ldap. As far as I know, auth_cache_size is the option to enable caching in all databases. But, is there any option I could use to disable it in a specific password database? -- Angel L.

Re: [Dovecot] Imap process crash: assertion failed: (full_fs_access)
by Joseph Tam 11 Feb '13

11 Feb '13

Any guess at what would cause this? Feb 7 21:20:53 server dovecot: imap(user): Panic: file mailbox-list-fs-iter.c: line 447 (fs_list_get_roots): assertion failed: (full_fs_access) (Sorry, no core dump) According to my logs, this user couldn't start an IMAP session for a 2 hour stretch for hundreds of connections. Then the problem seemed to have went away. I logged back as that user using a master password, but couldn't recreate this problem. The backtrace is just hex numbers (stripped executables) and I didn't drop privileges, so it refused to drop core, so that's no help. Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] Moving index files on another disk: no troubles but need more assurances
by Paolo Miotto 11 Feb '13

11 Feb '13

Hi, I'm using dovecot 1.2.15 on debian squeeze with maildir, and I want to move index files out of the mailboxes disk to reduce disk I/O. I need to get the assurance that the switch is completely transparent to my clients (IMAP and POP). I read the wiki documentation and have found this thread (http://dovecot.org/pipermail/dovecot/2009-September/042665.html) which makes me confident, even if it speaks of a older version and only pop3. So I set up a test server, copied a true mailbox and changed mail location from: mail_location = maildir:~/Maildir to mail_location = maildir:~/Maildir:INDEX=/srv/indexes/%1n/%n (all users under the same domain, no need to use %d). On the IMAP side all seems to work fine, new indexes are created in the new location (dovecot.index.log on 1st access, dovecot.index.cache on message manipolation). A test client (evolution) doesn't notice at all, and I have verified via a telnet imap session that UIDs don't change. But I see that when I move the indexes the IMAP HIGHESTMODSEQ response changes and is reset to 1. Can this baffle the clients? On the rfc I don't found reference to this status walking backwards. Need I to verify that all messages have the virtual size (W=nnnn) in the file name (the mailboxes are from a previous cyrus installation, then we switch to dovecot 1.2)? What other test you suggest that checking UIDL on the pop3 side? What happens if the indexes disk disappears (broken or removed from bay or all paths down for FC/iscsi)? Can dovecot 1.2 continue with INDEX=MEMORY as for a disk full? Sorry for the many questions....

[Dovecot] dovecot, postfix and sieve - broken by Ubuntu upgrade 10.10 -> 12.04

Hi! In upgrading from Ubuntu 10.10 to 12.04, my mail setup (dovecot using sieve and postfix) broke pretty badly.

[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.
