[Dovecot] Subject: IMAP crash on index
by Ruan Kendall 06 Jun '11

06 Jun '11

I'm running Dovecot 1.2.15 as an IMAP server on an up-to-date Debian v6 VM. I've recently upgraded the server from a pretty crusty old Debian v4 installation, though I don't recall exactly which version of Dovecot that would have been running. I guess I could try crawling through the old logs to check if it is likely to be useful. The upgrade seemed to have gone fine and I've been using the new server for about a week, but this morning I'm finding that whilst I can successfully connect to the IMAP server using Mutt, it can't display a mail index and a quick peek at the logs shows the IMAP process falling over: (account and server IP replaced) Jun 6 10:39:27 xen dovecot: Dovecot v1.2.15 starting up (core dumps disabled) Jun 6 10:39:27 xen dovecot: auth-worker(default): mysql: Connected to localhost (mail) Jun 6 10:39:34 xen dovecot: imap-login: Login: user=<example(a)example.org>, method=PLAIN, rip=::1, lip=::1, TLS Jun 6 10:39:35 xen dovecot: IMAP(example(a)example.org): Panic: file mail-index-view.c: line 264 (view_lookup_seq_range): assertion failed: (first_uid > 0) Jun 6 10:39:35 xen dovecot: IMAP(example(a)example.org): Raw backtrace: imap() [0x80f0e1e] -> imap() [0x80f0e82] -> imap() [0x80f0809] -> imap() [0x80ceb17] -> imap(mail_index_lookup_seq+0x26) [0x80ce5f6] -> imap() [0x80c481d] -> imap(mail_index_modseq_hdr_update+0x2e) [0x80c48ee] -> imap(mail_index_sync_ext_hdr_update+0xbb) [0x80de91b] -> imap(mail_index_sync_record+0x40f) [0x80cd57f] -> imap(mail_index_sync_map+0x2dd) [0x80cdfed] -> imap(mail_index_map+0x5c7) [0x80c3557] -> imap() [0x80bfd87] -> imap(mail_index_open+0x23f) [0x80c01ff] -> imap(index_storage_mailbox_open+0x71) [0x80abc81] -> imap(maildir_storage_sync_init+0x188) [0x8086c18] -> imap(mailbox_sync+0x31) [0x80b59d1] -> imap(imap_status_get+0x8a) [0x806f0ea] -> imap(cmd_status+0x123) [0x8065dd3] -> imap() [0x8067b5c] -> imap() [0x8067c32] -> imap(client_handle_input+0x175) [0x8067eb5] -> imap(client_input+0x5f) [0x80686ef] -> imap(io_loop_handler_run+0xd6) [0x80f9aa6] -> imap(io_loop_run+0x20) [0x80f8f20] -> imap(main+0x5b4) [0x8070f24] -> /lib/i Jun 6 10:39:35 xen dovecot: IMAP(example(a)example.org): 76] -> imap() [0x80603a1] Jun 6 10:39:35 xen dovecot: dovecot: child 20617 (imap) killed with signal 6 (core dumps disabled) I've not been able to find any mentions of this error occurring for other people.

[Dovecot] file rights for dictionary file
by Michael Köhler 06 Jun '11

06 Jun '11

Hi, I use Debian Squeeze and the sources from Stephan Bosch. A few weeks ago I´ve upgraded from 2.0.11 to 2.0.13 and got an error May 29 20:01:53 mailserver dovecot: dict: Error: Can't open configuration file /etc/dovecot/dovecot-dict-sql.conf.ext: Permission denied May 29 20:01:53 mailserver dovecot: dict: Error: Failed to initialize dictionary 'quota' and I could see that /etc/dovecot/dovecot-dict-sql.conf.ext is owning by root:root with 600. After changing to root:root 644 all works, but after each upgrade all files in /etc/dovecot will be set to 600. Is it a problem of the dovecot package or should I do some changes to config to allow dovecot reading the dict file?

[Dovecot] Bug: Fixed a duplicate
by Tom Sommer 06 Jun '11

06 Jun '11

I restored a dovecot mailserver today, and when I started the server again, the logs filled up with "Fixed a duplicate" warnings. This in itself it not a problem, the problem is that it appears the fix is not done correct. Consider this: Warning: Fixed a duplicate: [X]/cur/1305907573.V807I37682f3M146183.mail8.xxx.com:2,S -> 1306601066.M382668P27710.mail8.xxx.com The problem appears to be the timestamp of this new file isn't updated correctly. Now I got hundreds of mailboxes filled with mails named 1305907573.* with random (in the past) timestamps, leading to mangled miss-sorted inboxes for customers. 3575 May 25 02:05 1306600913.M982997P26976.mail8.xxx.com:2,S 55313 May 6 01:50 1306600913.M982998P26976.mail8.xxx.com:2,S 9839 May 7 23:59 1306600913.M982999P26976.mail8.xxx.com:2,S 3453 May 10 01:32 1306600913.M983000P26976.mail8.xxx.com:2,S 16616 May 14 00:22 1306600913.M983001P26976.mail8.xxx.com:2,S 68850 May 25 00:46 1306600913.M983002P26976.mail8.xxx.com:2,S etc. Dovecot is v. 2.0.11 I guess I should have deleted all dovecot.* files after the restore, before I started dovecot? // Tom

[Dovecot] Custom sql query for keeping quota with dict-sql
by Marcin Mirosław 05 Jun '11

05 Jun '11

Hello! I'd like to setup quota for for virtualusers, i'm using both maildir++ and mdbox as storage, and i'm using postgresql to keep users. I'm keeping all users data in one table: [...] login text NOT NULL, domain text, password text, quota_mb integer NOT NULL DEFAULT 0 [... other columns ...] i'd like to keep present quota in such two columns: quota_dict_bytes integer NOT NULL DEFAULT 0, quota_dict_messages integer NOT NULL DEFAULT 0 I read wiki a little and it looks i can't define own sql queries, they appear to be hardcoded. Am i wrong? Is it possible to write own queries to get/set quota using such table schema? Or maybe there is diffrent way to track quota for diffrent storages? Regards! Marcin

[Dovecot] solr substring schema.xml
by Daniel Miller 03 Jun '11

03 Jun '11

I'm trying a modified schema.xml with solr - it appears I now have substring searches! I took the schema.xml file shipped with Dovecot, and modified the text field definition to be: <fieldType name="text" class="solr.TextField" positionIncrementGap="100"> <analyzer type="index"> <tokenizer class="solr.WhitespaceTokenizerFactory"/> <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt"/> <filter class="solr.WordDelimiterFilterFactory" generateWordParts="1" generateNumberParts="1" catenateWords="1" catenateNumbers="1" catenateAll="0"/> <filter class="solr.LowerCaseFilterFactory"/> <filter class="solr.SnowballPorterFilterFactory" protected="protwords.txt"/> <filter class="solr.NGramFilterFactory" minGramSize="3" maxGramSize="15"/> <filter class="solr.RemoveDuplicatesTokenFilterFactory"/> </analyzer> <analyzer type="query"> <tokenizer class="solr.WhitespaceTokenizerFactory"/> <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true"/> <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt"/> <filter class="solr.WordDelimiterFilterFactory" generateWordParts="1" generateNumberParts="1" catenateWords="0" catenateNumbers="0" catenateAll="0"/> <filter class="solr.LowerCaseFilterFactory"/> <filter class="solr.SnowballPorterFilterFactory" protected="protwords.txt"/> <filter class="solr.RemoveDuplicatesTokenFilterFactory"/> </analyzer> </fieldType> Changing to the new "SnowballPorter" instead of the deprecated "EnglishPorter" filters is probably minor - the magic is the "NGramFilterFactory". 3 & 15 seemed reasonable defaults for the min/max size to search on. -- Daniel

[Dovecot] unexpected subfolder locaton in Maildir/.INBOX.subfolder

Hallo, I try to migrate existing imap server to dovecot 1.2 in debian squeeze if I connect to imap://user@host/INBOX Inbox works as expected and I get the content of Maildir/{cur,new,tmp} Maildir/.subfolder already exists if I connect to imap://user@host/INBOX.subfolder I get "folder not found" if I do a imap directory listing (raw mutt config, no subscriptions) - I see "../" - If I navigate to "../" I se all my existing subfolders if I create a new folder via imap the folder is created in Maildir/.INBOX.new_subfolder I expect the creation of Maildir/.new_subfolder This doesn't fit to the client configs and if I move the existing folders it doesn't fit to existing delivery agent filters and settings. I enabled mail_debug and the expansion looks ok for me: dovecot: imap-login: Login: user=<wulf>, method=PLAIN, rip=85.178.xx.xxx, lip=80.81.xxx.xxx, TLS dovecot: IMAP(wulf): Effective uid=112, gid=114, home=/var/mail/home/wulf dovecot: IMAP(wulf): maildir: data=~/Maildir dovecot: IMAP(wulf): maildir++: root=/var/mail/home/wulf/Maildir, index=, control=, inbox=/var/mail/home/wulf/Maildir the existing subscription information from courier-imap looks like INBOX.subolder Yes I can sed them to subfolder (of course I have to copy them to Maildir/subscriptions anyhow) But is that the idea?

[Dovecot] Running a dovecot cluster with mixed versions?
by Ian Foutch 03 Jun '11

03 Jun '11

I have been trying to find information and possible issues with running a cluster of dovecot server with different versions without any luck. We have an existing cluster with dovecot v1.1.10 and tried migrating to a new cluster with dovecot v2.0.12. We ran into some issues when we moved traffic to the new cluster and have been unable to reproduce it in our own testing. We may need to put real usage on the new servers but would like to be able to do this by adding newer servers into the existing cluster. What are the potential issues with doing this?

However i wanted to change the pass_scheme to something stronger than plain-md5, so i started by reading the wiki. I found this: http://wiki2.dovecot.org/HowTo/ConvertPasswordSchemes But when i comment out "default_pass_scheme" and i create the pass with the {SHA256.hex} prefix i see this in the logs: auth: Error: sql(xxx(a)xxxxxx.com,10.21.1.1): Password in passdb is not in expected scheme SHA256.hex I tried with several algorithms, but it seems to be something in my config that it's only working with plain-md5. the auth_mechanism is plain with ssl/tls. Maybe someone can give me a hint of where to see o which config file review. Thanks in advance. Eduardo.

[Dovecot] slow squat fts index creation
by Cor Bosman 03 Jun '11

03 Jun '11

Hi all, ive been playing with squat indexes. Up to about 300.000 emails in a single mailbox this was working flawlessly. The search index file is about 500MB at that time. Ive now added some more emails, and at 450.000 or so emails im seeing a serious problem with squat index creation. It takes...f o r e v e r . The .tmp file is being so slowly, it will probably take 2-3 hours to create. Upto this point it took maybe a minute. Im doing this in an openvz container, so theoretically i may be hitting some openvz resource limit. But ive upped all the limits and dont see any improvements. I dont see any resources starvation either. Could there be some dovecot issue when the search index reaches say 1GB? (im estimating that it's now trying to save about 1GB search index). Regards, Cor

Hi All, I need your help to limit the size of the Trash folder. I want to exclude the Trash folder in my user quota. But I do not want the Trash folder can not exceed 10M for example. I can manage to exclude the size of the Trash folder. But I can not limit the size of the folder. On my test, I've bytes=512000 for the Trash folder. But the user can move more that 512000B on the Trash folder ... Could you help me please ?

[Dovecot] Error: file_dotlock_create failed: Permission denied
by M. Fioretti 03 Jun '11

03 Jun '11

Hi, I have a Fedora 14 x86_64 computer. I run dovecot 2.0.12 on it, only to keep a local imap copy of all my email, in maildir format. A couple days ago the hard disk broke, so I bought a new one, and reinstalled Fedora 14 x86_64 with all the updates. Then I copied all the maildirs from a backup to the new drive. But I can't access email now. No matter how I change sticky bits or ownership and permissions of all the involved files and directories, etc.. Login succeeds, but I get this error whenever I try to create new mailboxes or access existing ones: May 25 13:36:03 polaris dovecot: imap-login: Login: user=<marco>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=8489, secured May 25 13:36:06 polaris dovecot: imap(marco): Error: file_dotlock_open(/home/z/email/marco/dovecot.index.log) failed: Permission denied (euid=500(marco) egid=500(marco) missing +w perm: /home/z/email/marco, euid is not dir owner) May 25 13:36:06 polaris dovecot: imap(marco): Error: file_dotlock_create(/home/z/email/marco/dovecot-uidlist) failed: Permission denied (euid=500(marco) egid=500(marco) missing +w perm: /home/z/email/marco, euid is not dir owner) May 25 13:36:06 polaris dovecot: imap(marco): Error: file_dotlock_create(/home/z/email/marco/dovecot-uidlist) failed: Permission denied (euid=500(marco) egid=500(marco) missing +w perm: /home/z/email/marco, euid is not dir owner) May 25 13:36:06 polaris dovecot: imap(marco): Error: opendir(/home/z/email/marco/new) failed: Permission denied (euid=500(marco) egid=500(marco) missing +r perm: /home/z/email/marco/new, euid is not dir owner) May 25 13:36:06 polaris dovecot: imap(marco): Error: file_dotlock_create(/home/z/email/marco/dovecot-uidlist) failed: Permission denied (euid=500(marco) egid=500(marco) missing +w perm: /home/z/email/marco, euid is not dir owner) Again, this doesn't change changing ownership.

[Dovecot] Squat Question!
by Henrique Fernandes 03 Jun '11

03 Jun '11

Hello folks, I use dovecot squat for indexing. I use to have fts_squat = partial=4 full=4 But i change to fts_squat = partial=4 full=8 My question is, do i need to delete older indexes to have it consistenly, or dovecot is able "update" the indexes or it sees that it is broken and rebuild it all? Other question, is there an comand line to update the indexes ? Thanks a lot! []'sf.rique

[Dovecot] This is appear a fts bug
by Antonio Perez-Aranda 03 Jun '11

03 Jun '11

I have checked this on dovecot 2.0.9 and 2.0.13 with fts-solr without patching. If you execute the follow IMAP script, then the imap process die by and a "assert" . select "inbox." . search text something After search, the connection is aborted in the client side, and imap process died on the server. When the log in dovecot says: (fts_backend_solr_init): assertion failed: (*box_name != '\0') After debug the code, there isn't in context any possibility to get "box_name". With squat plugin it is running. -- Antonio Pérez-Aranda Alcaide aperezaranda(a)yaco.es Yaco Sistemas S.L. http://www.yaco.es/ C/ Rioja 5, 41001 Sevilla Teléfono +34 954 50 00 57 Fax +34 954 50 09 29

[Dovecot] shared folders "invisible" on new setup
by Torsten Harenberg 03 Jun '11

03 Jun '11

Dear list, I hope this is not an old issue, but I couldn't find a solution even after google'ing quite some time. I try to migrate our institute's mail server (~200 users) from an old cyrus-based Mac installation to a new machine (NetBSD, dovecot 2.0.13). Everything went quite smoothly so far, but we are used to have "shared folders" ("public" folders in dovecot) and I simply couldn't make them to appear. I have two separate folders for private (user) mails and for public ones (yes, I set everything to 777 for the moment to avoid file access problems) : mailserver# pwd /var/mail mailserver# ls -al total 8 drwxrwxrwt 4 dovecot wheel 512 May 31 12:26 . drwxr-xr-x 28 root wheel 512 Mar 29 15:05 .. drwxrwxrwx 3 root mail 512 May 31 15:18 public drwxrwxrwx 4 root wheel 512 May 31 12:26 user In the public folder there is a shared folder named "fb8": mailserver# pwd /var/mail/public mailserver# ls -al total 8 drwxrwxrwx 3 root mail 512 May 31 15:18 . drwxrwxrwt 4 dovecot wheel 512 May 31 12:26 .. -rw-rw-rw- 1 10001 mail 0 May 31 15:14 dovecot-acl-list -rwxrwxrwx 1 root mail 0 May 31 11:06 dovecot-shared drwxrwxrwx 5 root mail 512 May 31 12:03 fb8 Now my own username (LDAP-based) is "harenber" and I try to subscribe myself to this list: mailserver# doveadm mailbox subscribe -u harenber public.fb8 mailserver# So a "subscriptions" file appears: mailserver# ls -al total 8 drwxrwxrwx 3 root mail 512 May 31 15:18 . drwxrwxrwt 4 dovecot wheel 512 May 31 12:26 .. -rw-rw-rw- 1 10001 mail 0 May 31 15:14 dovecot-acl-list -rwxrwxrwx 1 root mail 0 May 31 11:06 dovecot-shared drwxrwxrwx 5 root mail 512 May 31 12:03 fb8 -rw-rw-rw- 1 10001 mail 4 May 31 15:18 subscriptions mailserver# cat subscriptions fb8 mailserver# (although I think this is wrong, as I have namespace { list = children location = maildir:/var/mail/public:INDEX=~/public prefix = public. separator = . subscriptions = no type = public } I would assume this file to appear somewhere in /var/mail/user/harenber/public... ) But I cannot access this "fb8" folder with any client.

[Dovecot] Dovecot 2 + Director: IMAP+GSSAPI and LMTP-proxying
by Jahnke-Zumbusch, Dirk 03 Jun '11

03 Jun '11

Hi all, I have a setup of some nodes running Dovecot 2.0.13 and Postfix 2.5.6 with storage in NFS and authentication happening with PAM. Poking around in the wiki, I tried out different possibilities but now I am stuck -- and are hoping for your (enlightening) comments and tips. My planned setup for IMAP and LMTP is like this: IMAP ==== 1. A loadbalancer directs new sessions to a Dovecot-Director instance; this extra amount of traffic routing is mostly done for automatic handling in case of a failing Director node; this works fine, the same IP will end always on the same backend, but user-based Directory proxying seems more appropriate, especially taking the NFS-setup and the delivery process into account 2. Then the Director decides where to direct the user's session; this works fine when I let the backend servers do the authentication work 3. The backend Dovecot server will happily provide the user's e-mail For now my section for the passdb in the Director instance is passdb { driver = static args = proxy=y nopassword=y } So the backend will do the authentication of the session. But this setup inhibits using Kerberos, as the TGT is not forwarded to the backend server. I would very much like to provide GSSAPI/Kerberos authentication, which already works fine with the backend servers being directly connected by mail clients. The backend servers are using the PAM driver. I could not figure out, how to setup the passdb entry for the director instance to use PAM (this way enabling GSSAPI/Kerberos) and also giving back the necessary "proxy=y" to make director proxying the IMAP session. Is this setup feasible at all? LMTP ==== 1. Postfix accepts incoming e-mail and decides, which e-mail will go the LMTP-way to be deliverd into a Dovecot mailbox with something like virtual_transport = lmtp:inet:DOVECOT-DIRECTORS-IP:LMTP-PORT-ABC 2. the Dovecot Director instance accepts the LMTP connections and will proxy this to the appropriate==user's current backend server For now Postfix delivers e-mails using LMTP to the _backend_ w/o proxying and everything like SIEVE-filtering works fine: virtual_transport = lmtp:inet:DOVECOT-BACKENDS-IP:LMTP-PORT-XYZ But when I use the Director's IP/Port combination for LMTP, I see an error "554 5.4.6 <the(a)addr.ess> Proxying loops to itself". Where may I specify the port number of the backend server's LMTP-port? I suspect that the missing port number implies that the receiving LMTP-backend server uses the same port and so this would lead to a loop, hence the loop error?! I browsed the Wiki and the archives but still cannot find the information I am looking for. Any hints on that?

[Dovecot] doveadm "-S <socket_path>" option enabled in 2.0.8?

I apologize if this is a stupid question but I just compiled 2.0.8 and am trying to use doveadm to get the quota for a user using the -S <socket_path> option because I have different options for the various local IPs that dovecot listens on. For example, my default quota is filesystem (NFS rquota) and I can get that by doing: doveadm quota get -u warden which tells me: Quota name Type Value Limit % User quota STORAGE 1313476 1766400 74 But when I try to get my quota on a different local IP using the -S flag to doveadm: doveadm quota get -u warden -S 137.238.2.244:143 I am told: get: invalid option -- S The strange thing is doveadm's usage says that the -S option is valid for quite a few commands and in the man pages for those commands it looks like they should work for the way I'm calling doveadm. In the 2.0.8 source I also see code that looks like it should be parsing the -S flag. I can telnet to 127.0.0.1:143 and do ". getquotaroot inbox" which gives me the same information as "doveadm quota get -u warden" and I can telnet to 137.238.2.244:143 and ". getquotaroot inbox" also tells me my quota, but I'm hoping to use doveadm to periodically recalc my Maildir++ quota and update the squat FTS indexes and for that to happen doveadm needs to be able to be told what local IP address/port to connect to (I think). Here's my doveconf -n: # 2.0.8: /etc/dovecot/dovecot.conf # OS: Linux 2.6.18-194.26.1.0.1.el5 x86_64 Red Hat Enterprise Linux Server release 5.5 (Tikanga) nfs auth_cache_size = 10 M auth_master_user_separator = * auth_mechanisms = plain login auth_username_format = %Ln deliver_log_format = msgid="%m" subject="%s" from="%f" size=%p result="%$" first_valid_uid = 0 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_location = maildir:/home/%Lu/Maildir:CONTROL=/Mail/mailhome/%Lu/.dovecot:INDEX=/Mail/mailhome/%Lu/.dovecot mail_log_prefix = "service=%s user=%u rip=%r lip=%l " mail_nfs_storage = yes mail_plugins = zlib quota mail_log notify fts fts_squat 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 mbox_write_locks = fcntl namespace { inbox = yes location = 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 { autocreate = Trash autocreate2 = Drafts autocreate3 = Sent autosubscribe = Trash autosubscribe2 = Drafts autosubscribe3 = Sent 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 = fs:User quota quota_exceeded_message = Quota exceeded (mailbox for user is full).

[Dovecot] [dovecot] notifications when delivery fails
by Héctor Moreno Blanco 03 Jun '11

03 Jun '11

Hello Timo, We have dovecot 1.2.13. Is there any way to send notifications to the postmaster when a delivery fails? For example, when the dovecot index are corrupted and the mail is not sent to the user (the user who sent the message receives an error informing that the mail has not sent). Thank you very much in advanced.

[Dovecot] 2.0: deliver run from multiple uids and configuration files
by Arkadiusz Miskiewicz 03 Jun '11

03 Jun '11

I'm trying to run deliver from exim transport in a way that it doesn't need to query userdb AND doesn't need to read configuration files. The problem is that config files are readable for root only and if I run deliver with multiple UIDs then I would have to allow reading config files for everyone. Of course that's not a option because configs contain database passwords and such stuff. I wonder if it is possible to avoid reading config files by deliver? The only solution I see it to run deliver via sudo which doesn't look nice. -- Arkadiusz Miśkiewicz PLD/Linux Team arekm / maven.pl http://ftp.pld-linux.org/

[Dovecot] LMTP/Sieve/sendmail path
by Andreas Schulze 03 Jun '11

03 Jun '11

Hello, I have a system using postfix multi instance feature. The first, main postfix-instance is a nullclient as suggested by http://www.postfix.org/MULTI_INSTANCE_README.html#split The second instance is for real use. Postfix receive mail and handover them to the dovecot lmtp server. Thats working. The lmtp server supports sieve. One account has activated a vacation rule. So while delivering a mail to this account, dovecot creates a new mail based on the vacation rules. *This one* fail. It is injected in the main postfix instance, which is wrong in this case. I tried to start dovecot with an additional environment MAIL_CONFIG=/etc/postfix-instance2 and enabled alternate_config_directories in main.cf of the first insance. ( http://www.postfix.org/postconf.5.html#alternate_config_directories ) I also configured the userdb to return an extrafield userdb_mail_config=/etc/postfix-instance2. But all produce strance postfix errors I never saw in my last 6 years as postfix-admin. Would it be possible to configure dovecot lmtp server to use an external smtp-server to submit new mails ? Any other Ideas ?

[Dovecot] Baffled after upgrade
by Bert Todger 02 Jun '11

02 Jun '11

Hello all, I have just upgraded my Fedora 13 system to F15. With it came a shiny new dovecot 2.0.13 (Details of dovecot -n below). The configuration is different from the dovecot 1.something that I had been used to with F13, but I managed to get it working and all was well... Without changing anything related to dovecot (as far as I know), after a reboot, dovecot stopped working. I did a bit of digging, upped the verbosity of logging and found this in the logs: =======8<================================================================= Jun 02 09:58:21 auth: Debug: passwd-file /etc/passwd.dovecot: Read 3 users Jun 02 09:58:21 auth: Debug: auth client connected (pid=16699) Jun 02 09:58:21 auth: Debug: client in: AUTH 1 PLAIN service=imap secured lip=192.168.2.2 rip=192.168.2.2 lport=993 rport=33960 Jun 02 09:58:21 auth: Debug: client out: CONT 1 Jun 02 09:58:21 auth: Debug: client in: CONT 1 AG1hcmsAaWxIYWFkSFA= Jun 02 09:58:21 auth: Debug: Loading modules from directory: /usr/lib/dovecot/auth Jun 02 09:58:21 auth: Debug: Module loaded: /usr/lib/dovecot/auth/libauthdb_ldap.so Jun 02 09:58:21 auth: Debug: Module loaded: /usr/lib/dovecot/auth/libdriver_sqlite.so Jun 02 09:58:21 auth: Debug: Module loaded: /usr/lib/dovecot/auth/libmech_gssapi.so Jun 02 09:58:21 auth: Debug: passwd-file /etc/passwd.dovecot: Read 3 users Jun 02 09:58:21 auth: Debug: pam(mark,192.168.2.2): lookup service=dovecot Jun 02 09:58:21 auth: Debug: pam(mark,192.168.2.2): #1/1 style=1 msg=Password: Jun 02 09:58:23 auth: Info: pam(mark,192.168.2.2): pam_authenticate() failed: Authentication failure (password mismatch?)

I am puzzled by the reference to PAM authentication in the logs and in the dovecot -n output. Should I comment out all references to PAM? (in auth-system.conf.ext?) I and my family access mail through a variety of means, using Evolution on the home network, mobile devices (eg iPhone), webmail (using squirrelmail configured to access dovecot) and over ssh (using mutt). I don't necessarily want my (or their) email passwords to be the same as our PAM logon passwords (and at the moment they're not). So for me PLAIN has been the best solution up until now. What is my best (and simplest) solution?

Hi, I'm trying to get sieve working with dovecot. I seem to have everything enabled but my scripts done seem to work. both sieve-filter (2000) and sieve (4190) are running along with pop3 and imap. I have a simple script which checks the email address and moves it to a folder. I'm at a loss as to what to check next. Thanks in advance, Matt

[Dovecot] Client IP log variable for proxy/director setups?
by Kelsey Cummings 01 Jun '11

01 Jun '11

Timo - it would be very convenient if we could get a variable that held the real client ip for use in logging with director/proxy setups. It's clearly already passed around in client->user->remote_ip but at this point, I don't see anyway to get it into the logs and it would take me ages to figure out the Right place to add it since client->user doesn't seem to be available in client-common.c: get_var_expand_table(..). Perhaps I'm missing something obvious? -- Kelsey Cummings - kgc(a)corp.sonic.net sonic.net, inc. System Architect 2260 Apollo Way 707.522.1000 Santa Rosa, CA 95407

[Dovecot] Email being stored in "cur" folder and not being downloaded in Thunderbird
by Jay Welch 27 May '11

27 May '11

Hi, I have recently noticed that a random number of emails are being stored in the "cur" folder under certain users and cannot be downloaded in Thunderbird. I have tried moving the emails from "cur" to "new" but everytime I try to download the email from Thunderbird, the emails go back to the "cur" folder. What could be causing this? What is the "cur" folder used for? I had thought that the "cur" folder was used for IMAP but all the users here are using POP. Also, I have tried testing this on Outlook and Outlook seems to download the files from "cur". Thanks

Is there any specific optimization/tunning on dovecot for use GFS2 on rhel6??, we have configured the director to make the user mailbox persistent in a node, we will thank's any help from you. we are interested in using GFS2 or NFS, we believe the problem is the locks, how can we improve this?? best regards, Aliet The results rhel 4.8 x86_64/GFS1 two nodes, shared FC lun on a SAN Totals: Logi List Stat Sele Fetc Fet2 Stor Dele Expu Appe Logo 100% 50% 50% 100% 100% 100% 50% 100% 100% 100% 100% 30% 5% 1- 2608 1321 1311 2608 2508 3545 547 2001 2493 2702 5282 2- 2810 1440 1430 2810 2688 3835 403 2154 2679 2925 5706 3- 2913 1457 1441 2908 2778 3913 417 2253 2773 3034 5924 4- 2814 1448 1412 2812 2695 3910 401 2186 2686 2929 5712 5- 2789 1464 1432 2787 2652 3774 427 2112 2649 2879 5676 6- 2843 1460 1444 2839 2722 3948 422 2164 2713 2957 5778 rhel6 x86_64/GFS2 two nodes, shared FC lun on a SAN(Used RDM in VMWare vSphere for GFS2 lun) Tunned cluster suite cluster.conf + <dlm plock_ownership="1" plock_rate_limit="0"/> <gfs_controld plock_rate_limit="0"/> Totals: Logi List Stat Sele Fetc Fet2 Stor Dele Expu Appe Logo 100% 50% 50% 100% 100% 100% 50% 100% 100% 100% 100% 30% 5% 1- 2730 1340 1356 2704 2644 3748 522 2125 2643 2662 5422 2- 3309 1618 1659 3294 3223 4658 531 2563 3221 3239 6596 3- 2131 1046 1017 2055 2025 2911 381 1608 2024 2052 4256 4- 2176 1055 1039 2082 2058 2947 377 1671 2058 2078 4344 5- 1859 928 931 1859 1800 2626 304 1454 1799 1801 3706 6- 2672 1322 1329 2672 2607 3758 464 2097 2606 2615 5326 rhel6 x86_64/GFS2 two nodes, shared FC lun on a SAN(Used RDM in VMWare vSphere for GFS2 lun) Cluster suite defaults configs for plocks Totals: Logi List Stat Sele Fetc Fet2 Stor Dele Expu Appe Logo 100% 50% 50% 100% 100% 100% 50% 100% 100% 100% 100% 30% 5% 1- 1417 644 676 1325 1305 1872 308 1048 1302 1318 2824 2- 837 378 392 742 726 1050 117 588 722 734 1658 3- 803 363 347 752 745 1069 153 597 744 750 1658 4- 1682 802 811 1587 1569 2261 291 1299 1569 1585 3360 5- 1146 583 564 1146 1037 1500 213 811 1037 1049 2290 6- 838 403 366 744 734 1057 152 561 731 736 1664 rhel6 x86_64 two nodes used NFS(NAS Freenas 0.8, nfsvers 3) Totals: Logi List Stat Sele Fetc Fet2 Stor Dele Expu Appe Logo 100% 50% 50% 100% 100% 100% 50% 100% 100% 100% 100% 30% 5% 1- 1382 699 691 1357 1063 1500 224 861 1053 1313 2694 2- 1634 785 799 1610 1459 2120 311 1192 1451 1570 3204 2- 1635 826 806 1611 1463 2088 345 1159 1459 1568 3190 3- 1574 758 781 1537 1403 2060 324 1135 1396 1504 3090 4- 1685 842 807 1653 1506 2135 349 1215 1504 1634 3344 5- 1766 850 893 1737 1582 2289 335 1288 1579 1705 3480 6- 1597 797 769 1572 1423 2007 313 1133 1420 1536 3142 rhel6 x86_64 local storage Totals: Logi List Stat Sele Fetc Fet2 Stor Dele Expu Appe Logo 100% 50% 50% 100% 100% 100% 50% 100% 100% 100% 100% 30% 5% 1- 7798 3868 3889 7706 7566 10713 1080 6089 7559 7688 15562 2- 7806 3879 3874 7716 7585 10873 1114 6018 7578 7696 15572 3- 7866 3910 3855 7773 7748 11053 1076 6253 7747 7761 15710 4- 7893 3978 3931 7802 7772 10988 1117 6197 7767 7789 15760 5- 7775 3853 3809 7683 7654 10897 1081 6142 7651 7675 15534 6- 7877 3919 3872 7789 7758 10986 1085 6218 7755 7773 15720

[Dovecot] Moving maildir mailboxes
by Willie Gillespie 26 May '11

26 May '11

I am using Maildir with Dovecot 1.2. (Config available if needed, but should be a simple question.) I have a bunch of mail that I would like to do a one-time move from a private namespace to a shared namespace. The namespaces are already set up, etc. Can I just move the folders to their new location? I am not merging with existing folders, they would be new subfolders. Thanks! - Willie

[Dovecot] 2.0.12 (fa2e92526716): Deleting mails and folders from public namespaces
by Binarus 26 May '11

26 May '11

Hello, we basically run a dovecot imap setup where users' mailboxes are in private namespaces (as usual), but there is a public namespace with several thousand deeply nested folders also. The client we use is Thunderbird 3. The public namespace shows up in each user's account at the top level (i.e. same level as Inbox, Sent and so on), and users can make new subfolders in the public namespace, copy mails to it and so on. So, our setup basically works. But whenever a user tries to delete a folder from the public namespace, dovecot gives the following error: "Renaming not supported across non-private namespaces". I think I have a grasp why this happens (Thunderbird tries to move the folder from the public namespace into the trash folder (private namespace) of the user who does the deletion), and I also have read Timo's statement that he does not plan to support such renaming due to big problems he is seeing with it. Nevertheless, since deleting a folder from a public archive is not a too uncommon thing, I wanted to ask how other people have solved that. It came to my mind to configure Thunderbird to immediately delete folders and messages (instead of moving them to trash folder). I have tested that, and it worked, but is somehow dangerous and unsatisfying. Furthermore, I haven't completely understood the reason for the different behaviour of folders in the public namespace and a single message therein. If I configure Thunderbird to use the trash folder, users can delete messages from the public namespace, i.e. Thunderbird can move messages from the public namespace to the private trash folder of the respective account. This is obviously not true for folders (even if they are empty). What's the difference between an empty folder and a single message in this respect? Is it really the ACL thing which makes folders so difficult to handle opposed to single messages? Thank you very much for any ideas!

26 May '11

Hello folks, i am lookign in the wiki, but did not find anything very clear about what i want. I need to have namespace for each user from mysql. But like, i need all configruation comming from mysql, not only the location. Is that possible? here: http://wiki2.dovecot.org/Namespaces at section: Per-user Namespace Location From SQLI can set the location, is there an way to make everything ? Like the name of namespace, and etc ? Thanks to all! []'sf.rique

[Dovecot] v1.1.20 vs v1.2 & v2.0
by Adam 25 May '11

25 May '11

I am currently running v1.1.20 and was wondering if there is any compelling reason to upgrade to v1.2 or v2.0? For example is there any security updates in v1.2 or v2.0 that aren't included in v1.1.20? The other major thing I would be interested in knowing is there any speed enhancements in the newer versions? I am using basic PAM Auth and Maildir mailboxes on a Linux box. Let me know if you need any more information to answer my questions. Thanks, Adam

[Dovecot] problems with debian 5.0 and thunderbird
by Steven Jones 25 May '11

25 May '11

Hi, Does anyone have a setup guide for Thunderbird and Dovecot on Debian please? Dovecot is 1.0.15 I have Dovecot running listening on 143 and I can telnet from the XP guest but Thunderbird cant or wont talk to it. I have taken the # off listen and I get a telnet reply, no firewall is configured.... Ive set thunderbird up lots so I suspect its not Thunderbird but a dovecot config I have wrong. regards

[Dovecot] libwrap does it work on in 2.0?
by a.smith＠ukgrid.net 24 May '11

24 May '11

Hi, I noticed recently that libwrap (TCP Wrappers) is supported, although disabled by default, in the current Dovecot 2.0 but doesn't seem to be mentioned anywhere on the wiki. Is this working well/at all? Anyone care with experience using this care to share their experiences? My OS is FreeBSD, I noticed on some Linux distributions there may be issues, but this won't affect my installation. thanks Andy.
