[Dovecot] question about changing certificate
by oni-neko＠gmx.net 13 Jun '12

13 Jun '12

Good day! I'm having trouble changing certificate/keys for my dovecot(version 1.2.9). When I set up the server (unbuntu lts 10.4.4) I did it with a self-signed certificate. I can't remember exactly what I did, just that I followed the wiki and it worked fine =) Now I have to change the certificate because a friend bought an official one (from thawte) and I'm a bit stumped. As dovecot can use supposedly use the same file for both key and cert file, I copied the new certificate to /etc/ssl/private/dovecot.pem and to /etc/ssl/certs/dovecot.pem. next I get from managesieve-login, pop3-login and imap-login the following log entries: Fatal: Can't load private key file /etc/ssl/private/dovecot.pem: Key is for a different cert than /etc/ssl/certs/dovecot.pem some googling brought up the file ssl-cert-snakeoil.key in /etc/ssl/private and /etc/ssl/certs that some people change in that context. As I also have a symlink /etc/ssl/private/ssl-mail.key that points to /etc/ssl/private/ssl-cert-snakeoil.key I'm starting to be confused (even more). dovecot is using the dovecot.pem-files, who/what uses the ssl-mail.key? I'm pretty sure I'm just overlooking something completely obvious, but what? =) greetings silvia -- NEU: FreePhone 3-fach-Flat mit kostenlosem Smartphone!

[Dovecot] 2.1.7 shared folder index issued
by Alex Crow 12 Jun '12

12 Jun '12

Hi, Sorry to bother the list again so soon after fixing my own problem, but I now have this issue when clients try to view shared folders in Thunderbird (v12). They can see the shared folder, but the first time they click on in nothing happens. The second time they get an authentication failure. The third or fourth time it finally loads the shared mailbox, and I see this a few times in the logs: Jun 11 19:57:43 alsace dovecot: imap(sharedviewer(a)integrafin.co.uk): Error: mdbox map /home/indexes/integrafin.co.uk/t/sharedviewer/shared/sharedviewee(a)integrafin.co.uk/storage/dovecot.map.index corrupted: U nexpectedly lost shared/viewee(a)integrafin.co.uk/INBOX uid=73129 map_uid=74192 Jun 11 19:57:43 alsace dovecot: imap(sharedviewer(a)integrafin.co.uk): Disconnected: Internal error occurred.

Other than license issues, is there an advantage to using gnutls vs openssl? Or is openssl superior - at least in the current implementations? -- Daniel

[Dovecot] auth_krb5_keytab ignored ?
by Leon Meßner 12 Jun '12

12 Jun '12

Hi list, i noticed that when doing imap gssapi authentication with kerberos, dovecot (here 2.1.7) always searches /etc/krb5.keytab although i have auth_krb5_keytab = /etc/mail3.krb5.keytab in my etc/dovecot/dovecot.conf and doveconf -n also show this setting. If i combine the keytabs in krb5.keytab it works. Is there another location where i should put my configuration regarding gssapi/kerberos ? Thanks, Leon logs: 18:48_root@mail3:/root# cat /var/log/dovecot.log | tail -n 8 Jun 08 18:48:16 auth: Debug: client in: AUTH 1 GSSAPI service=imap secured session=gexTxPjBZACClTqR lip=130.149.58.164 rip=130.149.58.145 lport=993 rport=31076 Jun 08 18:48:16 auth: Debug: gssapi(?,130.149.58.145,<gexTxPjBZACClTqR>): Obtaining credentials for imap(a)mail3.physik-pool.tu-berlin.de Jun 08 18:48:16 auth: Debug: client out: CONT 1 Jun 08 18:48:16 auth: Debug: client in: CONT<hidden> Jun 08 18:48:16 auth: Info: gssapi(?,130.149.58.145,<gexTxPjBZACClTqR>): While processing incoming data: Miscellaneous failure (see text) Jun 08 18:48:16 auth: Info: gssapi(?,130.149.58.145,<gexTxPjBZACClTqR>): While processing incoming data: Failed to find imap/mail3.physik-pool.tu-berlin.de(a)PCPOOL.PHYSIK.TU-BERLIN.DE(kvno 1) in keytab FILE:/etc/krb5.keytab (des3-cbc-sha1) Jun 08 18:48:18 auth: Debug: client out: FAIL 1 Jun 08 18:48:23 imap-login: Info: Aborted login (auth failed, 1 attempts in 7 secs): user=<>, method=GSSAPI, rip=130.149.58.145, lip=130.149.58.164, TLS, session=<gexTxPjBZACClTqR> # 2.1.7: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 8.2-RELEASE-p3 amd64 auth_debug = yes auth_gssapi_hostname = mail3.physik-pool.tu-berlin.de auth_krb5_keytab = /etc/mail3.krb5.keytab auth_mechanisms = gssapi plain login auth_verbose = yes auth_worker_max_count = 120 first_valid_gid = 300 first_valid_uid = 200 lda_mailbox_autocreate = yes listen = mail3.physik.tu-berlin.de log_path = /var/log/dovecot.log mail_fsync = always mail_location = maildir:~/maildir mail_nfs_index = yes mail_nfs_storage = yes mail_privileged_group = mail 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 mmap_disable = yes namespace { inbox = yes location = prefix = separator = / type = private } namespace { location = mbox:~/mail prefix = mail/ separator = / type = private } passdb { args = session=yes failure_show_msg=yes max_requests=100 dovecot driver = pam } plugin { quota = fs sieve = ~/.dovecot.sieve sieve_dir = ~/.sieve } protocols = imap pop3 service auth { unix_listener auth-client { mode = 0660 } unix_listener auth-master { mode = 0600 } user = root } service imap-login { inet_listener imap { port = 0 } process_limit = 256 process_min_avail = 6 } service managesieve-login { process_limit = 256 process_min_avail = 6 } service pop3-login { inet_listener pop3 { port = 0 } process_limit = 256 process_min_avail = 6 } ssl_cert = </etc/private/mail3.physik.tu-berlin.de.pem ssl_key = </etc/private/physik.tu-berlin.de_privatekey.pem userdb { args = blocking=yes driver = passwd } verbose_proctitle = yes protocol lda { info_log_path = /var/log/dovecot-lda.log log_path = /var/log/dovecot-lda.log mail_plugins = " sieve quota" }

[Dovecot] Authentication issue
by Emiliano Rago 12 Jun '12

12 Jun '12

Hi, I need to set up a weird dovecot configuration: 1) outside a ssl tunnel I'd like to authenticate only with cram-md5 scheme 2) inside a ssl tunnel I'd like to authenticate only with plain auth The first is easily satisfied with auth_mechanisms = plain cram-md5 disable_plaintext_auth = yes but I don't know how to satisfy the second condition, if it's possible. Thanks for help, Emiliano Rago

[Dovecot] Getting duplicates despite trying hard to match lock styles
by Richard Walker 12 Jun '12

12 Jun '12

I'm attempting to replace (a) a very old setup that has POP (qpopper) access to inboxes and a separate UW IMAP server that provides folders, with (b) a shiny new mail setup with dovecot providing both inboxes and IMAP support. For the new mail server I created a virtual machine running a minimal Fedora 16 installation and installed sendmail, MIMEDefang, SpamAssassin, ClamAV, procmail, and dovecot. I have kept installing updates as they become available. For now I'm running the old and new mail setups in parallel; I have configured the original sendmail server to forward copies of incoming messages to the new sendmail running on the virtual machine. I then compare the results (e.g., how spam filtering is working). I've kept as much as possible of the original _style_ of setup as possible, which in particular means using sendmail, and message delivery through procmail to mbox files in /var/spool/mail. The key difference is the use of dovecot to provide IMAP access to the inbox and IMAP folders. Because of the legacy setup, my desktop access to email is via Thunderbird 2.0.0.22 on a very old Mac PowerBook G4 to work with both old and new setups and I have two windows open to make comparison possible. (Yes, both mail servers are on separate computers, not on this notebook.) Mostly this is working fine (after a fair bit of tweaking, including adding custom SELinux rules to get rid of all AVCs). I put the notebook to sleep overnight, and in the morning I open it up and see what happens. After a few minutes, the window with the old setup does its POP fetch; the window with the new setup almost straightaway shows the new messages in its version of the inbox. Not quite: again, for legacy reasons I have some Thunderbird filters, and I have duplicated those (still within Thunderbird) for the new setup. The filters are: 1. Move messages tagged as spam by SpamAssassin to the Junk folder. 2. Move messages from GeoNetwork-related senders to a "GeoNetwork" folder. 3. Move all remaining messages to the "In" folder. Most mornings this works just fine. But not always. Sometimes I get duplicates in the "In" and "GeoNetwork" folders of the new dovecot-based setup. I used to get _garbled_ duplicates (with extra random bits of other messages at the end of the duplicates) in the new setup, which I presumed must be due to a locking configuration mismatch. Having fixed that (see below) I no longer get garbled duplicates, but I do still sometimes (including today) get identical duplicates. This seems to happen when one of the incoming messages has a very large attachment - but you may wish to treat that as hearsay. I attach below: 0. The line from /etc/mtab on the new server that covers the filesystem (i.e., including /var/spool and /home). 1. Output of "doveconf -n" and a note about how I modified locking from the Fedora default. 2. Output of "procmail -v". 3. Sendmail procmail mailer config (for good measure; I don't think you need this). 4. An excerpt from /var/log/maillog on the new server showing the beginning of dovecot processing this morning when I opened my notebook. 5. A link to the dovecot raw log files of my "INBOX" and "In" folder processing from this morning. You'll see from the dovecot log files that Thunderbird sends expunge commands, but the expunged messages hang around -- indeed, the same messages get expunged several times! And eventually they get fetched again -- hence the duplicates I see in Thunderbird. Given that INBOX.out contains: 08:56:53.765423 * 537 EXISTS 08:56:53.765423 * 533 RECENT and then, after many expunges: 08:56:58.441341 * 16 EXPUNGE 08:56:58.441341 * 11 EXPUNGE 08:56:58.441341 * 3 EXPUNGE 08:56:58.441341 * 539 EXISTS 08:56:58.441341 * 536 RECENT 08:56:58.441341 9 OK Expunge completed. it looks like I still have a locking problem. I have tried very hard to understand the locking options in dovecot.conf and to match dovecot with procmail -- apparently, there is more to do. 0. The line from /etc/mtab for the filesystem: ---------- /dev/mapper/vg_f16i386serverbasic-lv_root / ext4 rw,seclabel,relatime,user_xattr,acl,barrier=1,data=ordered 0 0 ---------- 1. doveconf -n says: ---------- # 2.0.20: /etc/dovecot/dovecot.conf # OS: Linux 3.3.6-3.fc16.i686.PAE i686 Fedora release 16 (Verne) mail_debug = yes mail_privileged_group = mail namespace { hidden = yes inbox = yes list = no location = mbox:~/mail:INBOX=/var/spool/mail/%u prefix = "#mbox/" separator = / type = private } namespace { inbox = no location = maildir:~/Maildir prefix = separator = / type = private } passdb { driver = pam } service imap-login { inet_listener imap { address = localhost } } service imap { executable = imap postlogin } service pop3-login { inet_listener pop3 { address = localhost } } service postlogin { executable = script-login -d rawlog -t } ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = passwd } ---------- Note that the default Fedora installation specifies: mbox_write_locks = fcntl and I commented that out.

Because I have trouble comparing times in epoch format, I've run the logs through a little filter that replaces the timestamps at the beginning of each line with a timestamp in HH:MM:SS.nanosecond format in local time. I've carefully deleted lots of (what I hope are) lines you don't need from the logs. E.g., I deleted the middle section of a block of FETCH statements, leaving the first few and the last few. Please let me know if I deleted too much -- I was trying to be helpful. And of course I replaced e-mail address/subject lines/etc with XXXXXXXXXX. Although the Thunderbird filters are "supposed" to be run in the order I listed above, it seems that Thunderbird fetches all headers, works out what messages should be filtered to which folders, and then sends corresponding IMAP commands that copy the messages to the other folders in a _different_ order of the filters. (I.e., the INBOX log shows copy/store/expunge operations in the order "In", "Junk", then "GeoNetwork", rather than "Junk", "GeoNetwork", "In".) I have renamed the in/out log files as INBOX.in, INBOX.out, In.in, In.out and uploaded them to: https://sites.google.com/site/rwdownloadssite/dovecot-logs Thanks in advance to anyone who is willing to take a look and advise what I need to do.

[Dovecot] Dovecot auth process delays exiting if LDAPS passdb used
by SATOH Fumiyasu 11 Jun '12

11 Jun '12

Hi, I'm using Dovecot 2.1.6 and LDAP server as a backend for Postfix SMTP-Auth (SASL) on Debian GNU/Linux (wheezy), Solaris 10 and AIX 6.1/7.1. If Dovecot passdb is configured with LDAP (no TLS/SSL), it is no problem. But if Dovecot passdb is configured with LDAPS (or LDAP+TLS), Dovecot auth process has a problem that Dovecot auth delays exiting about between 20 and 60 seconds when Dovecot dovecot (master) process is already terminated by an administrator. Is this known problem? On AIX, this problem prevents restart Dovecot service by the following error: May 24 00:42:03 build-aix6 mail:warn|warning dovecot: master: Warning: Killed with signal 15 (by pid=11337890 uid=0 code=kill) May 24 00:42:10 build-aix6 mail:err|error dovecot: master: Error: service(auth): Socket already exists: /opt/osstech/var/run/dovecot/auth-login May 24 00:42:11 build-aix6 mail:crit dovecot: master: Fatal: Failed to start listeners My Dovecot 2.1.6 platforms are: * Debian GNU/Linux wheezy + OpenLDAP 2.4.28 (linked with GNU TLS 2.12.18) * Solaris 10 + OpenLDAP 2.4.26 (linked with OpenSSL 0.9.7) * AIX 6.1 + OpenLDAP 2.4.31 (linked with OpenSSL 1.0.0) * AIX 7.1 + OpenLDAP 2.4.28 (linked with OpenSSL 1.0.0) Because I see the problem on the all of above, there is a bug in Dovecot 2.1.6, I think.

[Dovecot] Director problems
by Joseba Torre 11 Jun '12

11 Jun '12

Hi, I've just setup a testing enviroment for director, and it's not working as expected. I have just 1 director (called director) and 2 dovecot servers (dovecot1 and dovecot2); these are exact copies. First problem: when both dovecot servers are up, every imap connection is redirected to the same server as you can see here: $ sudo doveadm director map user mail server ip expire time <unknown> 158.227.4.186 2012-06-06 13:34:12 <unknown> 158.227.4.186 2012-06-06 13:34:27 <unknown> 158.227.4.186 2012-06-06 13:34:34 (I don't know if that <unknown> is good or not) I've tried with 3 different users and ips to no change, users are always directed to the same host. Second problem: if I try to add/remove/modify one of the dovecot servers, the output of doveadm director map/status seems to be ok, but any new user connection fails with this log: Jun 6 14:51:59 director dovecot: director: Warning: Delaying new user requests until ring is synced Jun 6 14:52:27 director dovecot: director: Error: director: User test1 host lookup failed: Timeout - queued for 30 secs (Ring not synced for 73 secs) Jun 6 14:52:31 director dovecot: imap-login: Aborted login (auth failed, 1 attempts in 34 secs): user=<>, method=PLAIN, rip=158.227.4.186, lip=158.227.4.185, TLS, session=<Oyx9O83B/wCe4wS6> Any clue?

[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 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.

[Dovecot] Accessing maildir snapshots through dovecot / namespace
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...

[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
