[Dovecot] multi-instance doveadm user -m woes
by David Warden 11 Jun '12

11 Jun '12

I'm having difficulty with the doveadm who command on a multi-instance setup of dovecot. When I run the who command on the non-standard instance with the -m flag (to see their mail location), this happens: [root@wardentest3 dovecot]# doveadm -i mailtest user -m warden doveadm(root): Error: user warden: Initialization failed: Namespace 'INBOX.': Ambiguous mail location setting, don't know what to do with it: /var/spool/mail/root (try prefixing it with mbox: or maildir:) I tried adding my mail_location setting as location to both of my legacy and default namespaces, but got the same error. I also tried adding the -a flag like so: doveadm user -a /var/run/dovecot/mailtest/auth-userdb -m warden doveadm(root): Error: userdb lookup: connect(/var/run/dovecot/auth-userdb) failed: Connection refused (the default instance is currently stopped) and combining -a and -i out of curiosity: [root@wardentest3 conf.d]# doveadm -i mailtest user -a /var/run/dovecot/mailtest/auth-userdb -m warden doveadm(root): Error: user warden: Initialization failed: Namespace 'INBOX.': Ambiguous mail location setting, don't know what to do with it: /var/spool/mail/root (try prefixing it with mbox: or maildir:) I have 2 instances, default and mailtest: [root@wardentest3 conf.d]# doveadm instance list path name last used running /var/run/dovecot/mailtest mailtest 2012-05-11 10:57:16 yes /var/run/dovecot default 2012-05-11 10:54:09 no my doveconf -n for the mailtest instance: # 2.1.6: mailtest/dovecot.conf doveconf: Warning: service auth { client_limit=4096 } is lower than required under max. load (12288) doveconf: Warning: service anvil { client_limit=4096 } is lower than required under max. load (12291) # OS: Linux 2.6.32-220.13.1.el6.x86_64 x86_64 Red Hat Enterprise Linux Server release 6.2 (Santiago) nfs auth_cache_negative_ttl = 0 auth_cache_size = 16 M auth_gssapi_hostname = $ALL auth_krb5_keytab = /etc/dovecot/mailtest/mail.combined.keytab auth_master_user_separator = * auth_mechanisms = plain login gssapi auth_username_format = %Ln base_dir = /var/run/dovecot/mailtest/ default_client_limit = 4096 default_process_limit = 4096 deliver_log_format = msgid="%m" subject="%s" from="%f" size=%p result="%$" first_valid_uid = 0 hostname = mailtest.geneseo.edu instance_name = mailtest lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes login_log_format_elements = user=%u method=%m rip=%r lip=%l lport=%a mpid=%e encryption=%c mail_fsync = always mail_location = maildir:/Mail/mailhome/%Ln/mailtest/Maildir:CONTROL=/Mail/mailhome/%Ln/mailtest/.dovecot-control:INDEX=/Mail/mailhome/%Ln/mailtest/.dovecot-index mail_log_prefix = "service=%s user=%u rip=%r " mail_nfs_index = yes mail_nfs_storage = yes mail_plugins = zlib quota mail_log notify fts fts_squat stats maildir_very_dirty_syncs = yes managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave mbox_write_locks = fcntl mmap_disable = yes namespace default { inbox = yes location = mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Junk { auto = no special_use = \Junk } mailbox Sent { auto = subscribe special_use = \Sent } mailbox Trash { auto = subscribe special_use = \Trash } prefix = separator = . subscriptions = yes type = private } namespace legacy { alias_for = hidden = yes inbox = no list = no location = mailbox INBOX.Drafts { auto = no special_use = \Drafts } mailbox INBOX.Junk { auto = no special_use = \Junk } mailbox INBOX.Sent { auto = no special_use = \Sent } mailbox INBOX.Trash { auto = no special_use = \Trash } prefix = INBOX. separator = . type = private } passdb { args = /etc/dovecot/passwd.masterusers driver = passwd-file master = yes } passdb { args = cache_key=%u dovecot driver = pam } plugin { fts = squat mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename flag_change append mail_log_fields = uid box msgid size from subject flags mail_log_group_events = yes quota = maildir:User quota quota_exceeded_message = Quota exceeded (mailbox for user is full).

[Dovecot] dsync migration with preserving pop3 uidl
by Tomáš Herceg 11 Jun '12

11 Jun '12

Hi all, I'm trying to migrate messages from icewarp (merak) mailserver to dovecot via dsync, IMAP migration is looking fine, but I'm unable to migrate pop3 uidls from originating server, probably is something wrong with configuration, but I don't know what. The only documentation i found is on the wiki: http://wiki2.dovecot.org/Migration/Dsync where is bad writen mail_plugins = pop3-migration, i corrected it to mail_plugins = pop3_migration, but it still didn't work, here is my configuration: dovecot --version 2.1.5 dovecot -n # 2.1.5: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-220.13.1.el6.centos.plus.x86_64 x86_64 CentOS release 6.2 (Final)

I think the problem is likely the mdbox storage... There have always been some issues with it and the antispam plugin when combined.

I can only suggest, as a test, trying with some other storage format -- I only use Maildir -- to see if the problem is really in the interaction with mdbox. I'm fairly sure that's likely the problem, maybe the plugin doesn't pass something through append that is needed by mdbox, but I've never even attempted to understand mdbox. Maybe Timo can comment.

by Karl Oulmi 11 Jun '12

11 Jun '12

Hi, I've the following setup : - FreeBSD 9.0 / Dovecot 2.1.7 - Maildir storage over iSCSI (Dell MD3200i) - Virtual users over LDAP to render the storage snapshots available through dovecot (to allow my users to browse their mail history). Here is my conf : namespace { type = private inbox = yes list = yes prefix = INBOX. location = maildir:/home/%u/Maildir:CONTROL=/home/dovecot/control/%u:INDEX=/home/dovecot/indexes/%u } namespace snap { prefix = INBOX.snapshot.h0. hidden = no inbox = no list = yes location = maildir:/da1/%u/Maildir:INDEX=/da1/dovecot/indexes/%u:CONTROL=/da1/dovecot/control/%u type = private } The problem is that I don't see the content of the inbox folder contained in the snapshots whereas subfolders are perfectly viewed ! Inbox cur|new are is /da1/%u/Maildir/ If anyone have a tip, It would be nice... Regards, Karl. -- _______________________________________________________________ Karl OULMI Centre de Ressources Informatiques Institut de Biologie de Lille - CNRS GDS3366 _______________________________________________________________

[Dovecot] dovecot does not find libpam when compiling with customized prefix
by Roland 11 Jun '12

11 Jun '12

Hello everybody, I try to compile dovecot 2.1.7 with a customized --prefix setting and --with-pam . Although I installed libpam into the same --prefix, dovecot does not find it: checking for pam_start in -lpam... no configure: error: Can't build with PAM support: libpam not found The same or a similar problem seems to have appeared 4 years ago: http://www.dovecot.org/list/dovecot/2008-February/028750.html Which libpam file does dovecot expect in which directory? And possibly there is something wrong with the pam_start function? Thanks in advance, Roland

[Dovecot] Dovecot over NFS
by James Devine 11 Jun '12

11 Jun '12

I'm playing with running dovecot over NFS and I am running into some issues. I have followed the guide at http://wiki2.dovecot.org/NFS and my setup includes 1 nfs server and 1 client running postfix/dovecot. In testing I am running postal via the command: postal -t 10 -c 10 localhost users399 The test file has a list of 399 users to deliver to. I've provided a sample of the errors I'm receiving and my configuration below, I am running dovecot 2.0.19. Any idea what I might be doing wrong and what I might do to resolve it? My ultimate goal is to setup multiple clients with director so each user is still handled on a single machine, however with a single machine I still seem to be having issues. Here is a sample of some of the errors I'm seeing: Jun 6 15:55:12 test-gluster-client1 dovecot: lmtp(12072, testuser130): Error: mdbox /mnt/testuser130/mdbox/mailboxes/INBOX/dbox-Mails: Invalid dbox header size: 0 Jun 6 15:55:12 test-gluster-client1 dovecot: lmtp(11999, testuser99): Error: Log synchronization error at seq=2,offset=556 for /mnt/testuser99/mdbox/storage/dovecot.map.index: Append with UID 2, but next_uid = 3 Jun 6 15:55:14 test-gluster-client1 dovecot: lmtp(12047, testuser41): Error: mdbox /mnt/testuser41/mdbox/mailboxes/INBOX/dbox-Mails: Invalid dbox header size: 0 Jun 6 15:55:18 test-gluster-client1 dovecot: lmtp(12133, testuser138): Error: Log synchronization error at seq=2,offset=556 for /mnt/testuser138/mdbox/storage/dovecot.map.index: Append with UID 2, but next_uid = 3 Jun 6 15:55:19 test-gluster-client1 dovecot: lmtp(12076, testuser217): Error: mdbox /mnt/testuser217/mdbox/mailboxes/INBOX/dbox-Mails: Invalid dbox header size: 0 Jun 6 15:55:19 test-gluster-client1 dovecot: lmtp(12047, testuser41): Error: mdbox /mnt/testuser41/mdbox/mailboxes/INBOX/dbox-Mails: Invalid dbox header size: 0 Jun 6 15:55:23 test-gluster-client1 dovecot: lmtp(11985, testuser166): Error: mdbox /mnt/testuser166/mdbox/mailboxes/INBOX/dbox-Mails: Invalid dbox header size: 0 Jun 6 15:55:23 test-gluster-client1 dovecot: lmtp(12072, testuser130): Error: Log synchronization error at seq=2,offset=204 for /mnt/testuser130/mdbox/mailboxes/INBOX/dbox-Mails/dovecot.index: uid_validity updated unexpectedly: 1339019655 -> 1339019656 Jun 6 15:55:23 test-gluster-client1 dovecot: lmtp(11928, testuser130): Error: Log synchronization error at seq=2,offset=204 for /mnt/testuser130/mdbox/mailboxes/INBOX/dbox-Mails/dovecot.index: uid_validity updated unexpectedly: 1339019655 -> 1339019656 Jun 6 15:55:24 test-gluster-client1 dovecot: lmtp(11954, testuser192): Error: mdbox /mnt/testuser192/mdbox/mailboxes/INBOX/dbox-Mails: Invalid dbox header size: 0 Jun 6 15:55:24 test-gluster-client1 dovecot: lmtp(12130, testuser128): Error: mdbox /mnt/testuser128/mdbox/mailboxes/INBOX/dbox-Mails: Invalid dbox header size: 0 Jun 6 15:55:27 test-gluster-client1 dovecot: lmtp(12076, testuser217): Error: mdbox /mnt/testuser217/mdbox/mailboxes/INBOX/dbox-Mails: Invalid dbox header size: 0 Jun 6 15:55:27 test-gluster-client1 dovecot: lmtp(12211, testuser60): Error: mdbox /mnt/testuser60/mdbox/mailboxes/INBOX/dbox-Mails: Invalid dbox header size: 0 Jun 6 15:55:27 test-gluster-client1 dovecot: lmtp(12112, testuser190): Error: mdbox /mnt/testuser190/mdbox/mailboxes/INBOX/dbox-Mails: Invalid dbox header size: 0 Jun 6 15:55:27 test-gluster-client1 dovecot: lmtp(12047, testuser41): Error: Log synchronization error at seq=2,offset=204 for /mnt/testuser41/mdbox/mailboxes/INBOX/dbox-Mails/dovecot.index: uid_validity updated unexpectedly: 1339019658 -> 1339019659 Jun 6 15:55:27 test-gluster-client1 dovecot: lmtp(11937, testuser41): Error: Log synchronization error at seq=2,offset=204 for /mnt/testuser41/mdbox/mailboxes/INBOX/dbox-Mails/dovecot.index: uid_validity updated unexpectedly: 1339019658 -> 1339019659 Jun 6 15:55:28 test-gluster-client1 dovecot: lmtp(11985, testuser166): Error: mdbox /mnt/testuser166/mdbox/mailboxes/INBOX/dbox-Mails: Invalid dbox header size: 0 Jun 6 15:55:30 test-gluster-client1 dovecot: lmtp(12130, testuser128): Error: mdbox /mnt/testuser128/mdbox/mailboxes/INBOX/dbox-Mails: Invalid dbox header size: 0 My dovecot config is: auth_debug = yes auth_debug_passwords = yes auth_username_format = %Ln auth_verbose = yes base_dir = /var/run/dovecot-service/ disable_plaintext_auth = no instance_name = dovecot-service mail_debug = yes mail_fsync = always mail_location = mdbox:~/mdbox mail_nfs_index = yes mail_nfs_storage = yes mail_plugins = quota mdbox_rotate_size = 16 M mmap_disable = yes passdb { driver = pam } plugin { quota = dict:User quota::file:%h/mdbox/dovecot-quota } protocols = " imap lmtp pop3" service auth { unix_listener auth-userdb { group = postfix mode = 0666 user = postfix } } service imap-login { inet_listener imap { port = 10143 } } service lmtp { inet_listener lmtp { port = 10024 } } service pop3-login { inet_listener pop3 { port = 10110 } } ssl = no ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd }

[Dovecot] Dovecot antispam plugin bug: got an empty message
by Petr Bravenec 10 Jun '12

10 Jun '12

It is few months ago I requested help with combination dovecot - dovecot- antispam plugin and dspam. Now I got into troubles with a lot of spam delivering to users inbox. Problem described bellow is now better hidden but stil remains: When moving a message from INBOX to Junk, dspam got an empty message. I made a wrapper about dspamc and there is no input on stdio. The dspam was not trained (got an empty message). Looking to source code of dspam and antispam plugin I suspect the dovecot not to sending any content to plugin when moving from inbox to junk.

[Dovecot] Restoring older messages to new server?
by Voytek Eymont 10 Jun '12

10 Jun '12

I had Dovcot 1.x setup, all was working well (till...) Server got stuffed up and same Dovecot 1.x was rebuilt, put back in service, all's working well. I have recovered data from Maildirs messages from the old server, As some of the inboxes now have new messages, what is correct way to copy older messages from old server to new server ? (There are no duplicates, simply old messages from past server, data is physically on new server) Thanks for pointers, Voytek -- Swyped on my Motrix with K-9 Mail. Please excuse my brevity.

[Dovecot] Dovecot setup fails w. multiple mail locations (gnus/dovecot/offlineimap)
by Johnny 10 Jun '12

10 Jun '12

Hi, I am trying to setup a Gnus - Dovecot - Offlineimap - Webmail (Gmail / Fastmail) chain and cannot configure the correct behaviour. Any advice to get this working properly would be very appreciated! I have set up Offlineimap to synchronise two mail accounts into separate folders under ~/Maildir. After running Offlineimap, the folders look as below. Maildir/ |-- Gmail | |-- cur | |-- dovecot.index.log | |-- dovecot-uidlist | |-- dovecot-uidvalidity | |-- dovecot-uidvalidity.4fd3b80e | |-- [Gmail].All\ Mail | |-- [Gmail].Drafts | |-- [Gmail].Important | |-- [Gmail].Sent\ Mail | |-- [Gmail].Spam | |-- [Gmail].Starred | |-- [Gmail].Trash | |-- INBOX | |-- new | |-- Personal | |-- Receipts | |-- tmp | |-- Travel | `-- Work `-- Fastmail |-- cur |-- dovecot.index.log |-- dovecot.mailbox.log |-- dovecot-uidlist |-- dovecot-uidvalidity |-- dovecot-uidvalidity.4fd3b75e |-- INBOX |-- INBOX.Drafts |-- INBOX.Sent\ Items `-- INBOX.Trash The Dovecot config is below. (I have set up a blank "MailTest" directory as inbox, believing that this may preserve the two imap directories better for offlineimap synching (not sure if this is correct)). ,---- | mail_location = maildir:~/Maildir:LAYOUT=fs | | namespace inbox { | location = maildir:~/MailTest | inbox = yes | } | | namespace mygmail { | type = private | separator = . | prefix = "mygmail." | location = maildir:%h/Maildir/Gmail/:LAYOUT=fs | inbox = no | hidden = no | list = yes | subscriptions = yes | } | | namespace myfastmail { | type = private | separator = . | prefix = "myfastmail." | location = maildir:%h/Maildir/FASTMAIL/:LAYOUT=fs | inbox = no | hidden = no | list = yes | subscriptions = yes | } `---- Accessing dovecot through gnus with this setup only sees the files in the directories that are not prefixed (e.g. under Fastmail, INBOX is the only seen folder, all INBOX.subfolder are not there). Removing the prefix manually they can be seen again however (e.g. INBOX.subfolder -> subfolder). If I remove LAYOUT=fs in the dovecot config, nothing is seen at all, although the directories look like proper Maildirs! A second issue is that running Offlineimap a second time seems to work ok for gmail, but Fastmail complains that "cannot create directory '.'"? Thanks! -- Johnny Dovecot 2.1.6 Offlineimap 6.5.2.1 Ma Gnus v0.6

[Dovecot] Upgrading 1.2.17 -> 2.1.x
by Adam G Tilghman 10 Jun '12

10 Jun '12

We're planning to upgrade our site from 1.2.17 to 2.1.x within the next few months, but we must ensure our ability to revert to 1.2.17 if problems arise. I don't expect our maildir storage would present a problem, but am less certain about 2.1.x index/control files remaining readable under 1.2.17. Should I have any reason to worry? -- Adam Tilghman Systems Support / Academic Computing & Media Services agt(a)ucsd.edu 858-822-0711 University of California, San Diego

[Dovecot] Deliver quota-warning via director
by Daniel Parthey 10 Jun '12

10 Jun '12

Hi there, I'm using NFS with Dovecot 2.0.20 and would like to deliver a quota warning to the user using the LMTP director. I have configured quota warnings according to http://wiki2.dovecot.org/Quota/Configuration But it seems that lda delivers the mail directly to the local filesystem and is not using our lmtp director, which prevents NFS mailboxes from getting corrupted. Is there a way to tell lda to use LMTP or the director and ignore the quota while delivering the notification? Regards Daniel

[Dovecot] Dovecot 1.x on AIX -> Dovecot 2.x on Ubuntu
by root＠yuma.acns.colostate.edu 10 Jun '12

10 Jun '12

We are working on migrating Dovecot 1.2.17 running on AIX 5.3 (believe it or not!) to Dovecot 2.0.13 running on Ubuntu. We have hundreds of users mboxes we will be migrating. My question is regarding the index files. Should we remove those after the migration, but before we open it up to users so Dovecot can create new ones? I did a test migration of a single user, and Dovecot detects the architecture change and put out some panic errors, corrupt files and backtrace messages in syslog on Ubuntu. The messages are shown below. If every user is going to generate these types of errors, I'm thinking maybe it makes sense to remove all the .imap directories and let Dovecot create new clean ones. I realize that may slow things down for awhile while Dovecot is rebuilding new files. Thanks for any info.

[Dovecot] director and doveadm server
by Angel L. Mateo 09 Jun '12

09 Jun '12

Hi, I've been reading doc at http://wiki2.dovecot.org/Director to configure my servers. My question is regarding configuration of doveadm server. I have configured both, director and backend servers, as described in that doc, but I don't know how to run doveadm commands in director servers. doveadm is working, because I can run commands, but they are executed in local (director) server. For example: root@myotis40:/etc/dovecot/conf.d# doveadm director status mail server ip vhosts users 155.54.211.169 100 1 but doveadm who seems to be executed just in local: (backend server) root@myotis30:/etc/dovecot/conf.d# doveadm who username # proto (pids) (ips) angel.luis 2 imap (11931 11936) (155.54.67.5) (director server) root@myotis40:/etc/dovecot/conf.d# doveadm who username # proto (pids) (ips) And another question about this... what is the local config option? I haven't found it documented anywhere. -- Angel L.

[Dovecot] director and IPs shown at the backends
by Angel L. Mateo 09 Jun '12

09 Jun '12

Hello, I am configuring a dovecot imap/pop servers with a dovecot director in front of them. Because I am using director proxy, connections in the backends are show as coming from director IPs. Is there any way to configure director (or backends) so the backends know (and report) the original IP instead of the director IP?

[Dovecot] Corrupted mdbox on LMTP director delivery while user is logged in via IMAP

09 Jun '12

[Dovecot] ntlm_auth in Dovecot
by Leonardo 09 Jun '12

09 Jun '12

Hi, I'm trying getting NTLM auth working against AD in my Dovecot 2.0.15. I'm getting the following error: Jun 08 14:18:11 auth: Info: winbind(?,10.44.3.151): user not authenticated: NT_STATUS_UNSUCCESSFUL "wbinfo -u" reports all the users of the domain and "ntlm_auth --username=%name% --domain="%domain%" gets authenticated successfully. Debugging winbind I can see the following error: [2012/06/08 14:18:11.129611, 10] winbindd/winbindd.c:651(process_request) process_request: unknown request fn number 14 [2012/06/08 14:18:11.129671, 10] winbindd/winbindd.c:738(winbind_client_response_written) winbind_client_response_written[2822:unknown request]: delivered response to client My dovecot.conf is the following: auth_mechanisms = plain ntlm login auth_username_format = %n auth_verbose = yes auth_winbind_helper_path = /usr/bin/ntlm_auth auth_use_winbind = yes auth_debug = yes disable_plaintext_auth = no info_log_path = /var/log/dovecot-info.log log_path = /var/log/dovecot.log mail_location = maildir:/var/mail/domains/%d/%n plugin { autocreate = Trash autocreate2 = Spam autocreate3 = Sent autosubscribe = Trash autosubscribe2 = Spam autosubscribe3 = Sent } protocols = imap ssl = no userdb { driver = static args = uid=100 gid=101 home=/var/mail/domains/%d/%n first_valid_uid=100 } passdb ldap { driver = ldap args = /etc/dovecot/dovecot-ldap.conf } protocol imap { mail_plugins = autocreate } Sounds like there is an issue when Dovecot runs "ntlm_auth". It doesn't appear to be a permission issue (perms are 755). Any help is appreciated. Thank you in advance. -- leonardo.

[Dovecot] [ Re: best practises for mail systems]
by Michescu Andrei 09 Jun '12

09 Jun '12

Hello, If disk space and bandwidth are affordable (and from your setup it seems that they are affordable as you have everything locally) I would split the mail storage completely and use replication in between n-master servers (n=2 for your case). The replication is not yet fully tested, but Timo is actively working on this feature. The fear of lossing the imap session does not make sense (at least to me) as the client will reconnect automatically in the background. Like this you have no SPOF and no split-brain and you get the flexibility (if needed) to geographically distribute your servers in the the future. Keep each server with its own ip, connect to them via DNS (round robin etc etc). We are currently experimenting with a setup similar to this one, but with geographically distributed servers (trans-continental) (bandwidth limited and high cost).

[Dovecot] Maildir filename has wrong S value

Hello folks, This morning I tried to open an old archive mail folder using Mutt. However, while fetching headers it aborted. Checking the dovecot log gave me this: @400000004fb21996267d37d4 imap(benv): Error: Cached message size smaller than expected (9115 < 9420) @400000004fb21996267e8bac imap(benv): Error: Maildir filename has wrong S value, renamed the file from /home/vpopmail/domains/benv.junerules.com/benv/Maildir/.Old.2009/cur/1260395566.28175.black,S=9115:2,S to /home/vpopmail/domains/benv.junerules.com/benv/Maildir/.Old.2009/cur/1260395566.28175.black,S=9420:2,S @400000004fb21996267e937c imap(benv): Error: Corrupted index cache file /home/vpopmail/domains/benv.junerules.com/benv/Maildir/.Old.2009/dovecot.index.cache: Broken physical size for mail UID 294 @400000004fb21996267eaaec imap(benv): Error: read(/home/vpopmail/domains/benv.junerules.com/benv/Maildir/.Old.2009/cur/1… failed: Input/output error (uid=294) @400000004fb219962680683c imap(benv): Info: Disconnected: Internal error occurred. Refer to server log for more information. [2012-05-15 10:53:32] in=6503 out=192718 I've retried opening this folder several times, but each time Dovecot only fixes 1 file and then aborts. (the folder apparently has a lot more files with incorrect sizes). My question here is: Why does dovecot abort? Isn't the issue fixed after the rename? Also: The files are not corrupted or unreadable, reading them through the commandline works fine. I've looked through my backups and saw that at least half a year ago this mismatch in size was already present. I've been running dovecot for quite a while, so the cause of this size mismatch might very well be a issue in an older version of dovecot / my configuration. Right now I'm running dovecot 2.1.6, but I've been running the v1.2 version for quite a while before that. Is this something that can be improved in dovecot so it doesn't abort after 1 rename? (of course I could script a rename operation, but that seems like a workaround to me) Thanks for reading. Wouter.

[Dovecot] 2.1.7 altmove not working
by Alex Crow 09 Jun '12

09 Jun '12

Hi list, I've just set up a 2.1.7 server, and have migrated a couple of accounts across from a 2.0.15 server, keeping the old configs. I have a strange problem on the new box in that altmove just doesn't work. I have my main storage under /home/email, indexes under /home/indexes and ALT under /home/email_archive. When I run the altmove command, the following broken symlink is created in /home/email/integrafin.co.uk/acrow: lrwxrwxrwx. 1 email email 54 Jun 8 10:46 dbox-alt-root -> /home/email_archive/integrafin.co.uk/a/acrow/mailboxes But nothing is created in the archive other than the empty directory: /home/email_archive/integrafin.co.uk/a/acrow. My mail_location is: mail_location = mdbox:/home/email/%d/%n:INDEX=/home/indexes/%d/%1n/%n:ALT=/home/email_archive/%d/%1n/%n This worked perfectly on the older server. I have attached my doveconf -a output. Any help much appreciated. Regards Alex
