[Dovecot] How to make Dovecot verbous
by Frank Walter 16 May '12

16 May '12

Hello I am struggling with Dovecot 2 (coming from Dovecot 1.0.10) with mysql Authentification for Postfix. I get errors when using it: dovecot: auth: Fatal: Unknown database driver 'mysql' dovecot: master: Error: service(auth): command startup failed, throttling But a first thing would be to log the real errors, if there are any, so I set in /etc/dovecot/conf.d/10-logging.conf auth_verbose, auth_verbose_passwords, auth_debug, auth_debug_passwords, mail_debug, verbose_ssl all to yes and I set: debug_log_path = /var/log/dovecot-debug.log but there is no logfile after restarting dovecot. How can I enable a (verbous) own Logfile in Dovecot? frank

I thought someone could make money coming up with an "unsend" and "untwitter" service that all it does is to queue the outgoing message for 5 minutes, during which the sender can re-consider and remove it from the queue. Sorot of like the kill-switch for live broadcasts. But as the saying goes, you can't make things foolproof, as they keep making better fools. As to the OP trying to determine whether an Email message has been read, an indirect and imperfect technique, used by spammers and marketing critters, is to web bug http://en.wikipedia.org/wiki/Web_bugs It works by placing innocuous individualized tags in HTML formatted Email e.g. "<img src="http://your.domain/?id={hash}>" that downloads a 1x1 dot). You can then correlate web logs with the hashes to see which messages got rendered. A hit does not necessarily mean it got read, and the absense does not mean it was ignored, but it's better than nothing. If you value your privacy, turn off HTML rendering on your Email reader.

[Dovecot] plugin: Don't allow deleting the last instance of a mail
by Timo Sirainen 16 May '12

16 May '12

Before beginning to code it, does anyone have any related ideas that could be useful before starting it? Mainly what I'm intending to do is to write a plugin for mdbox storage that allows users to expunge mails in a specific namespace only if there are other instances for the mail. So basically: * Users can't accidentally delete mails (in shared mailboxes) * Users can still move mails within folders For v2.1 this can be implemented only to a specific storage backend, so at least for now only mdbox will support it. Maildir and sdbox support would also be possible by looking at hard link counts. Race conditions would allow deleting the mails, but that's unlikely to be an issue since the main point is to avoid accidental deletions that shouldn't be attempted in the first place anyway.

[Dovecot] stats + fts squat plugins, indexer-worker error on message indexing
by David Warden 16 May '12

16 May '12

On RHEL 6.2 + dovecot 2.1.5 with the stats and fts (squat) plugins enabled and each user having their own uid on the system I get the following error in the logs when the indexer-worker process indexes some messages: Apr 25 09:56:19 wardentest3 dovecot: imap-login: Login: user=warden, method=PLAIN, rip=137.238.60.164, lip=137.238.2.240, lport=1993, mpid=19464, encryption=TLS Apr 25 09:56:26 wardentest3 dovecot: service=indexer-worker user=warden rip= Indexed 12 messages in INBOX Apr 25 09:56:26 wardentest3 dovecot: service=indexer-worker user=warden rip= Error: open(/proc/self/io) failed: Permission denied Apr 25 09:56:29 wardentest3 dovecot: service=imap user=warden rip=137.238.60.164 Disconnected: Logged out bytes(in/out)=46/780 What I did to generate the above was remove the squat indexes for my Inbox then log in via telnet and search for a string in my Inbox, which forced an index of the messages in my Inbox. Based on http://wiki2.dovecot.org/Services#indexer-worker it seems like this is because the indexer-worker process is created as root but at the time of indexing the indexer-worker drops privs to the mail user. In /proc/<indexer-worker pid>/, io is mode 0400 and owned by root, so it makes sense that the mail user would be unable to read that file. The strange thing is it looks like the stats are still collected (unless I am reading the output of the stats dump incorrectly): [root@wardentest3 mailtest]# doveadm stats dump -s /var/run/dovecot/mailtest/stats command user=warden cmd args session user last_update user_cpu sys_cpu min_faults maj_faults vol_cs invol_cs disk_input disk_output read_count read_bytes write_count write_bytes mail_lookup_path mail_lookup_attr mail_read_count mail_read_bytes mail_cache_hits select inbox 27fb87218302984f084c0000ae899e04 warden 1335362182.950250 0.000000 0.000000 172 0 46 0 0 12288 13 7883 4 381 0 0 0 0 0 search text "warden" 27fb87218302984f084c0000ae899e04 warden 1335362186.588023 0.001000 0.000000 32 0 4 1 0 0 4 108 1 43 0 0 0 0 0 logout 27fb87218302984f084c0000ae899e04 warden 1335362189.161790 0.000000 0.000000 1 0 0 3 0 0 1 108 3 157 0 0 0 0 0 This obviously isn't a show-stopper but if this is causing stats to be incorrect it would be great if this could be fixed. -David Warden My doveconf -n: # 2.1.5: /etc/dovecot/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 2.6.32-220.7.1.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 = $ALL auth_krb5_keytab = /etc/dovecot/mailtest.combined.keytab auth_master_user_separator = * auth_mechanisms = plain login gssapi auth_username_format = %Ln base_dir = /var/run/dovecot/mailtest/ default_client_limit = 4096 default_process_limit = 4096 deliver_log_format = msgid="%m" subject="%s" from="%f" size=%p result="%$" 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 = . 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] [Plugin dev] First-time-only cache lock failure
by John G 15 May '12

15 May '12

Hi This is a question related to plugin developement on Dovecot 2.1.4. I'm currently implementing a dovecot plugin that retrieves mails from a corporate server through an internal protocol. The plugin is very similar to the pop3c storage (lib-storage/index/pop3c). The plugin has to map original server UIDs to IMAP UIDs, using MAIL_CACHE_POP3_UIDL cache field the same way pop3c does. So, I've got a function similar to pop3c_sync_messages(), performing several mail_index_append() and mail_cache_add() calls. The problem is that on the first sync, when the index and cache files don't exist yet, there's a failure writing data in cache. The call to mail_index_sync_commit()\mail_cache_transaction_commit() fails because of mail_cache_transaction_lock(). The index and cache files are properly created, but the cache doesn't contain the MAIL_CACHE_POP3_UIDL values. It works properly on the second sync, the MAIL_CACHE_POP3_UIDL field being properly saved. Would you have some ideas on what could be wrong here? Thanks, John

I've had this working for over a month now with no problems. Then I suffered a power outage today, and now dovecot/auth dies as soon as I start dovecot. I've spent the past three hours searching google, but can't find even a hint at what's wrong with my server. As far as I can tell, this is the only thing that has failed after bringing the server back up when power was restored. Can anyone help me figure out what is wrong?

[Dovecot] default mail quota when using per user quota
by Andreas Helmcke 14 May '12

14 May '12

Hello, using dovecot 2.1 and per user mail quota via ldap is there a way to have a default quota which gets used, if the "quota" field in ldap is not set? I tried with: plugin { quota = maildir:User quota quota_rule = *:storage=3G } userdb { args = /etc/dovecot/dovecot-ldap.conf driver = ldap } and in dovecot-ldap.conf: user_attrs = dcMailQuota=quota_rule=*:storage=%$ but with this configuration the mail quota /allways/ gets loaded from ldap resulting in users without dcMailQuota attribute having no quota at all. Greetings Andreas

[Dovecot] doveadm not working
by Christian Rößner 14 May '12

14 May '12

Hi, I know I must have done some misconfiguration, but I do not know where to start searching for. All began when looking at my weekly cron message, where doveadm purge -A is run. That fails. So I tried doveadm quota -A as well, which several weeks ago was working perfectly. Example: doveadm quota get -A doveadm(root): Error: User listing returned failure doveadm: Error: Failed to iterate through some users Username Quota name Type Value Limit % All I see in the logs is: May 13 13:03:20 mx0 dovecot: auth: Error: auth worker: Aborted request: Lookup timed out May 13 13:03:21 mx0 dovecot: auth-worker(26753): Error: LDAP: ldap_start_tls_s() failed: Connect error May 13 13:03:21 mx0 dovecot: auth-worker(26753): Error: LDAP: ldap_start_tls_s() failed: Can't contact LDAP server Dovecot itself works. Only doveadm does not. My LDAP is using SASL/EXTERNAL. Certs are in standard folders under /etc/ssl/{certs,private} (see below). I guess that "some" user (but which?) tries to read the certs but is disallowed. Can somebody help me please to fix my permissions on that (private used) mail server? Is my "vmail" user required?

[Dovecot] Log files
by Chris Lasater 14 May '12

14 May '12

Hi, I just started using Dovecot and was trying to create separate logs instead of using syslog. Is there a way to get the file permission to be something other then root? I have tried the below configuration and it does not seem to change anything. The log process does change to a new user, but it still creates and writes as root. Whenever I test a new setting I delete all the current logs so they will have to be recreated to make sure it does not just keep the previous permissions. I also dont see much documentation on the service log. according to dovecot -a there are a good number of options, but I dont see any information about them. Here are my logging settings below and I am running 2.1.6 and tried on 2.1.5. ### Logging info_log_path = /home/user/dovecot/logs/dovecot_info.log log_path = /home/user/dovecot/logs/dovecot.log debug_log_path = /home/user/dovecot/logs/debug.log service log { user = user unix_listener log-errors { group = user2 mode = 0620 user = user } } Thanks, Chris

[Dovecot] dovecot report W value error and Corrupted index cache file

Hello everybody, I have a problem and no idea. Yesterday Dovecot.log report: Warning: Fixed a duplicate: /opt/*/cur/<time>.M*.<domain>,S=*,W=*:2,S -> <time>.M*.<domain> Now Dovecot.log report: Error: FETCH [ ] for mailbox INBOX UID 10546 got too little data: 79850 vs 81231 Error: Maildir filename has wrong W value: /opt/DIR/DOMAIN/USER/cur/1281317869.M*.*,S=79569,W=81231:2,S~ Error: Corrupted index cache file /opt/DIR/DOMAIN/USER/dovecot.index.cache: Broken virtual size for mail UID 10546 A few days ago, we used a new machine for mail server (and we used maildir format with dovecot-1.2.0).In fact ,we used iRedmail on CentOS5. And last week, I copy some mail data from old machine to new one through SCP and CP command. It worked well. Yesterday, I copy the mail data from old machine to new one through RSYNC. I guess maybe the errors have a relationship with rsync, because the new machine open SELinux and the rsync data error. Although the files were copyed to /cur directory , it seemed to appear the same mail file. Now,I receive some BLANK mails by pop3 of OutLook2007 . There are not any Header and any Body( Totally BLANK). Outlook show they are 760B size. I am confusing for this problem. Please help me. Thank you.

[Dovecot] userdb namespace settings bug
by Alexander 'Leo' Bergolth 14 May '12

14 May '12

Hi! Since upgrading to 2.1.6, setting namespaces via environment variables using a imap-postlogin-script *sometimes* doesn't work. Sometimes, the prefix of a namespace isn't set correctly, but is set to an empty string, which leads to the following error: namespace configuration error: Duplicate namespace prefix: "" However, the environment is set correctly, the error seems to occur when parsing the environment. See the attached log: The postlogin-script sets the environment variables attached as dovecot-postlogin-environment.txt. (dumped from postlogin script via env) However, the variable "NAMESPACE/S-GSD/PREFIX=Shared/GSD/" gets parsed as: plugin/namespace/s-gsd/prefix=Shared/GSD/ See the error message: Unknown userdb setting: plugin/namespace/s-gsd/prefix=Shared/GSD/ After restarting dovecot, the same configuration sometimes works correctly. I'd greatly appreciate your help! Unfortunately I have done the upgrade on a production system, so the issue is quite serious for me.. Will downgrading to 2.0 work? (Index-files, etc?)

[Dovecot] dovecot wants to access my music directory
by Ian Pilcher 14 May '12

14 May '12

I am getting an SELinux error every time dovecot starts, because it is trying to access my music directory (/srv/music). I've read the doveadm-mount man page, and tried: doveadm mount add /srv/music ignore but it didn't make any difference. Now, I certainly didn't tell dovecot to access this directory, so how can I tell it *not* to do so. This is dovecot-2.1.6-2.fc17.x86_64 on Fedora 17 Beta, BTW.

[Dovecot] index IO patterns
by Cor Bosman 12 May '12

12 May '12

Hey all, we're in the process of checking out alternatives to our index storage. We're currently storing indexes on a NetApp Metrocluster which works fine, but is very expensive. We're planning a few different setups and doing some actual performance tests on them. Does anyone know some of the IO patterns of the indexes? For instance: - mostly random reads or linear reads/writes? - average size of reads and writes? - how many read/writes on average for a specific mailbox size? Anyone do any measurements of this kind? Alternatively, does anyone have any experience with other redundant storage options? Im thinking things like MooseFS, DRBD, etc? regards, Cor

[Dovecot] /var/run/dovecot folder gets deleted on server reboot? ubuntu 10.10
by jacques 11 May '12

11 May '12

Hi After rebooting my server connections to the mail system set up there failed - on closer inspection no dovecot process was running or got started. When running as root /usr/share/sbin/dovecot -c /etc/dovecot/dovecot.conf got error on console /var/run/dovecot/auth-master could not be opened and found no /var/run/dovecot folder!. Is there better script to place in /etc/init.c/ to start dovecot (which will not fail silently?) Any idea what would remove the folder on ubuntu 10.10, running dovecot 2.1.5 and postfix 2.1.7? Any suggestions? Jacques

I've sorted out Postfix to correctly identify this and pass on to Dovecot for delivery but Dovecot doesn't seem to deliver where I want it to. Ideally I would like to have a structure so that mail is delivered to /var/mail/example.com/subdomain/user My users are stored in MySQL and they are being pulled out correctly, but dovecot is delivering to /var/mail/subdomain.example.com/tim Looking at my logs it seems that the mail location is being picked up not being acted on...

[Dovecot] Request for help with dovecot.conf file: configured to work with MySQL and Postfix.
by Femi Ajayi 10 May '12

10 May '12

Greetings, I have CentOS 6.2 running on our server with a VPS provider (Linode.com) I need to configure Postfix, dovecot, MySQL to work for virtual domains (multiple domains on our server). The only instructions for setting up Email with Postfix, Dovecot and MySQL my host provides is for the configuration on CentOS 5 which is here: http://library.linode.com/email/postfix/dovecot-mysql-centos-5 , I followed it for the installation/configuration of Email with Postfix, Dovecot and MySQL on our CentOS 6.2 Everything seemed to work fine until I got to the editing of the dovecot.conf file. The guide on the Linode Library provides instructions for Dovecot 1.x, while the newer versions of CentOS (CentOS 6) , apparently use Dovecot 2.x. The config file format has changed, so the one in the guide is no longer applicable, and as a result, I got a errors.. I would therefore appreciate it greatly if someone with a copy of the Dovecot 2.x dovecot.conf file configured to work with MySQL and Postfix (for handling mails for multiple domains) could share it with me. You could get a better understanding of the problem if you take some time to look at the instructions I followed so far: http://library.linode.com/email/postfix/dovecot-mysql-centos-5 ..and also the forums where I had previously sought help: http://forum.linode.com/viewtopic.php?p=50603#50603 http://www.linuxquestions.org/questions/showthread.php?p=4672839#post4672839 Thanks in anticipation of your help.

[Dovecot] Thunderbird log-in --->Authentication failed - password in uppercase in log files
by jacques 10 May '12

10 May '12

Hi I use dovecot 2.1.5 with postfix, amavis, spamassasin, mysql, virtual domains only. Dovecot being used for SASL authentication, and delivery. When I connect via telnet to port 25 or with smtp and try to do auth plain with mmencode connection string authentication works fine. I can send and recieve messages, and relay works as well. Trying to set up thunderbird to connect to this server I get problems - seems as if the password is resolved proper from the database (use postfixadmin), but then compares an upper case version of my password in the MD5-CRYPT() call to the password string obtained from the database. I do see the base64 encoded connection string in dovecot log though.

[Dovecot] BODYSTRUCTURE bug?
by A.L.E.C 10 May '12

10 May '12

Hi! I've found a bug in Content-Type parsing. It's old instance of dovecot 1.1. Maybe fixed in newer versions. I have a mail with header: Content-Type: multipart/signed; boundary="------------080705010808010608030700"; protocol="application/x-pkcs7-signature";micalg="SHA1" and it works, but when the boundary is in different order Content-Type: multipart/signed; protocol="application/x-pkcs7-signature";micalg="SHA1"; boundary="------------080705010808010608030700" dovecot returns wrong BODYSTRUCTURE: ("text" "plain" ("charset" "us-ascii") NIL NIL "7bit" 226233 2955 NIL NIL NIL NIL) If this has been fixed, in which version? -- Aleksander 'A.L.E.C' Machniak LAN Management System Developer [http://lms.org.pl] Roundcube Webmail Developer [http://roundcube.net] --------------------------------------------------- PGP: 19359DC1 @@ GG: 2275252 @@ WWW: http://alec.pl

[Dovecot] Enforcing Dovecot Quotas
by tcsmith1978 10 May '12

10 May '12

Hello, I have been looking at enforcing quotas for users of my mail system (postfix and Dovecot v1.2). Have tried to follow a few tuts on the web but its not having the desired effect. Essentially I can still send and receive mail on an account that I believe has had its quota exceeded. In my main.cf, I have: userdb sql { args = /etc/dovecot/mysql/dovecot-mysql.conf } passdb sql { args = /etc/dovecot/mysql/dovecot-mysql.conf } and... protocol lda { mail_plugins = quota } protocol imap { mail_plugins = quota imap_quota } plugin { quota_exceeded_message = You have exceeded the maximum quota for your mailbox } the dovecot sql (mysql) file has the following query for pulling out user ids and quotas etc: user_query = SELECT maildir, mymailuser as uid, mymailgroup as gid,concat('maildir:storage=',quota) as quota FROM virtual_mailbox WHERE username = '%u' I have set one of my users to have a quota of 1 (so one byte I believe) so it should be over the limit pretty much immediately. Looking at the logs I can see that the system is picking up on the quota limit but doesn't seem to enforce it. Apr 27 10:29:02 deliver(test(a)testdomain.com): Info: auth input: quota=maildir:storage=1 Apr 27 10:29:02 deliver(test(a)testdomain.com): Info: Quota root: name=storage=1 backend=maildir args= Any ideas?

Hello, the error is still present: May 8 19:47:18 opsys dovecot: imap-login: Disconnected (no auth attempts): rip=82.113.119.140, lip=78.46.216.126 Whenever I start a session with openssl to STARTTTL (Server: mail.opsys.de) the handshake is successfull. Also I am able to login to my account via 1 login. In Thunderbird port 993 for SSL/TLS works correct, only STARTTLS on port 143 isn't working properly. The cert is Class 1 and signed by StartCom Ltd.. Dovecot.conf (for viewable reasons of this mail pasted): http://pastie.org/private/bmrymyuo16ohzxdahf0nq And here openssl output: http://pastie.org/private/3rpgll2s7hblev9ozpcq8w Note the 'Verify return code: 21 (unable to verify the first certificate)' in the output...

Dovecot 2.1.6, with lmtp_save_to_detail_mailbox=yes recipient_delimiter=+ messages addressed to "user+detail@domain" are always delivered to INBOX regardless if "detail" mailbox already exists or lda_mailbox_autocreate=yes. Anything else needed to enable lmtp_save_to_detail_mailbox feature? Thanks, Oscar

[Dovecot] dovecot and systemd
by Michal Hlavinka 09 May '12

09 May '12

Hi all, dovecot supports systemd socket activation. Together with standard unit activation (like old sysv init script), there are two ways how to configure dovecot(only interface:port, not whole configuration). This can result in situation where those configurations does not say the same. Question is what should happen then? For example, lets have dovecot configured to listen for imap(s) and lets have systemd dovecot socket configured to listen for all protocols - pop3(s) and imap(s). When dovecot is configured to start on boot, systemd will start it and dovecot will listen on imap(s) ports. But when dovecot.socket is enabled, it'll listen on pop3(s) too and when new pop3 connection comes, it'll pass it to dovecot and dovecot will serve it. The question is: Should this happen? What exactly should happen when dovecot.conf does not match dovecot.socket configuration? Michal

[Dovecot] acls not copied when creating subfolder of private INBOX
by Andreas Helmcke 09 May '12

09 May '12

Using brand new dovecot 2.1.5 I still have a problem with the inheritance of acls. Setting: - maildir with private INBOX and public folders. - users maildir directory (/home/mail/user/ahelmcke) contains dovecot-acl file - public folders root directory (/home/mail/Fax) contains dovecot-acl file When creating a subfolder of the public folder the dovecot-acl files gets copied to the subfolders directory as expected. When creating a subfolder of the users INBOX the dovecot-acl files does /not/ get copied to the subfolders directory.

If you already have dovecot running in proxy mode it's easy to add pop3s.

A simple example: ssl = yes ssl_cert = </etc/dovecot/dovecot.pem ssl_key = </etc/dovecot/dovecot.pem service pop3-login { inet_listener pop3 { port = 110 } inet_listener pop3s { port = 995 ssl = yes } } Of course there is a lot more SSL tuning that can be done: http://wiki2.dovecot.org/SSL/DovecotConfiguration > -----Message d'origine----- From: David Jonas > Sent: Wednesday, May 02, 2012 10:29 PM > To: Gilles Albusac > Cc: dovecot(a)dovecot.org > Subject: Re: [Dovecot] Dovecot for POP3S proxying > > On Wed May 2 06:41:00 2012, Gilles Albusac wrote: >> I would like to configure Dovecot for POP3S proxying all users from >> the Internet to the internal Exchange Mail Server. > > Unless I'm missing something with your request, you don't need dovecot. > Any ssl proxy can do that for you, such as stunnel > (http://www.stunnel.org/) We use the hardware ssl termination on our > load balancers for pop3s, imaps, and smtps.

[Dovecot] IMAP NOTIFY extension
by ashley willis 09 May '12

09 May '12

your work on NOTIFY was brought to my attention, and I see it hasn't been changed in two months, a week after you announced it. a few users and some mail admins have been wanting something like this for k9 mail, which I help develop. what is the current status? is it worth installing and starting work in getting k9 to support it yet? I'd offer help on your end, but I just know java and perl. c code usually confuses me (i keep meaning to learn, but...). thanks! -ashley -- Sent from my Android phone with K-9 Mail.

[Dovecot] courier to dovecot
by Grafibit Rendszergazda 08 May '12

08 May '12

Dear All, I know there were many threads on this topic. I was searching the archive and the net also, but did not find a solution on my problem. I hope you can help me. I am migrating from an old server using courier to a new server with dovecot and i can not manage to have the same uids after the migration. After copying the message files from the old server to the new, and executing the script from the wiki page the messages are still re-downloaded by the mail clients. After telnet and logging in to the old server port 110, I got the following on the command *uidl*: 1 UID377-1278276092 2 UID387-1278276092 3 UID394-1278276092 4 UID498-1278276092 5 UID499-1278276092 6 UID564-1278276092 On the new server i set up the *pop3_uidl_format = UID%u-%v* because it seems for me that the old server is using the same uidl format. Either if i execute the /./courier-dovecot-migrate.pl --to-dovecot --recursive --convert /command or i don't the uidls on the new server won't be the same. Both the %u and %v numbers are differ. Please give me any hints how to continue the investigation to have a successful migration.

Re: [Dovecot] Upgrading known problems (2.0 to 2.1) ?
by Timo Sirainen 08 May '12

Yes, that's possible. The IMAP/POP3 servers behind Dovecot director wouldn't even need to be Dovecots at all. Although you really want to use v2.1 director since it has a lot of fixes compared to v2.0.

[Dovecot] Panic in index-sync.c: line 25 on dovecot-1.2.17

Hi, with dovecot-1.2.17 (yes i know it's old) i'm getting the folowing error after doing a system upgrade. May 7 22:04:26 mail dovecot: deliver(elon): Panic: file index-sync.c: line 25 (index_mailbox_set_recent_uid): assertion failed: (seq_range_exists(&ibox->recent_flags, uid)) May 7 22:04:27 mail kernel: pid 79989 (deliver), uid 4873: exited on signal 6 (core dumped) this only happens to one user and only with mail from one mailinglist (this one). Mails do get filtered by sieve. After some delivery attempts the mail finaly gets stored alright in the maildir.

The maildirs are on NFS and in this case only beeing used with my instance of mutt and two other postfix+dovecot servers which are quite idle. Whats the way to debug this ? Thanks, Leon

[Dovecot] Proxying for some users and having the rest local?
by Dr Josef Karthauser 07 May '12

07 May '12

I'm migrating a load of mailboxes from cyrus to a new dovecot server. What I'd like to do is to switch the DNS to dovecot, and set things up so that all old imap mailboxes are accessed through the dovecot proxy. That way I can migrate them one at a time independent of DNS issues. I've got a load of users specified in mysql, and that configuration works well for local mailboxes. How do I configure things so that I can switch proxy access on and off? What's I've got so far is: password_query = SELECT user, domain, password, "masteruser" as master, "masterpass" as pass, proxy, "remoteimap.server" as host FROM mailboxes \ WHERE user = '%n' AND isMailbox AND active AND domain = '%d' I imagined that I could switch the proxy per user by setting proxy='n' or proxy=null for any users that want to be local, and proxy='y' for any users that I want to forward on to the original server. It doesn't appear to work that way though. Irrespective of the proxy value dovecot appears to try and proxy all users. What am I doing wrong? I can't work it out from the docs, and the source will take quite a bit of studying to get to the bottom of it all. Thanks :), Joe

[Dovecot] This binary should probably be called with process group set to (vmail) instead of (userid)

Im sorry to ask another basic question, but Ive tried to find this answer for several hours now and it eludes me. Im getting the following when dovecot tries to deliver an email: May 6 19:29:21 mydomain dovecot: lda: Debug: auth input: jeff home=/opt/imapdata/j/jeff/INBOX uid=1001 gid=999 May 6 19:29:21 mydomain dovecot: lda(jeff): Fatal: setgid(999(vmail) from userdb lookup) failed with euid=999(vmail), gid=500(jeff), egid=500(jeff): Operation not permitted (This binary should probably be called with process group set to 999(vmail) instead of 500(jeff)) I cannot seem to find where its trying to call dovecot-lda with uid(jeff) at? AFAIK Ive set everything up to use/deliver as 'vmail'. 'jeff' is the only person on this box with a unix account which is uid 500, but how do I make it use vmail instead? Thanks for the help!
