[Dovecot] second fs quota root crashes
by Juergen Obermann 03 Nov '09

03 Nov '09

Hallo. In our dovecot 1.2.6 server running under Solaris 9 I would like to set up a second quota root because the mail folders are in the users home directories and the inboxes of all users are in /var/mail. As soon as I add quota2 = fs:INBOX:noenforcing:mount=/var/mail the imap client crashes repeatedly as soon as the user tries to open a mail folder. Thanks for any help.

[Dovecot] Author wanted for Dovecot article in Linux Magazine (Germany)
by Markus Feilner 31 Oct '09

31 Oct '09

Hi list, I am an editor at the German Linux Magazine and I am searching for an author or input on Dovecot, its advantages and especially the recent features. I had organized some authors, but unfortunately they don't have time right now. :-) Nevertheless I heard many positive comments on Dovecot. I can write or help writing the article, but I would love to have some input from an experienced dovecot admin - perhaps with some stunning, unusual setup that might interest our readers (most of them are skilled admins and programmers...) Something that can't be easily done with other mail servers would be great, something spectacular that is suitable to convince an mail admin why he should migrate to Dovecot. It won't be long, just about 2-3 pages (a maximum of 15000 characters) including screen shots and/or listings, code, > 10 Links and an author's biography with photo. Anybody interested? That would be great, feel free to send me a mail to: mfeilner(a)linuxnewmedia.de Unfortunately, we don't have much time, there's only two weeks left, but I will help and do a lot of work for the article.

[Dovecot] Dovecot in-house benchmarking
by Joseba Torre 30 Oct '09

30 Oct '09

Hi, Before some major changes in our infrastructure, I was interested in the performance impact of moving indexes to our NAS (Emc Celerra v5.5). So I downloaded both dovecot-1.1.19 and dovecot-1.2.6, compiled them and wrote 2 confs for each of them, one with local indexes and another with indexes in the NAS. Then I created 19 pam users, and tested system performance this way: - uninstall current installed version - install a new version - start dovecot - for each user run: imaptest user=user pass=pass host=localhost port=143 mbox=${MBOX} seed=123 secs=300 | tail -1 > file - stop dovecot I'm not sure if these tests are real, but our results are: * In our conf, 1.1.19 and 1.2.6 performance are roughly the same * Moving the indexes to our NAS makes the system 3 times slower As we currently only have 1 system accessing mails or indexes, I tried later with nfs_* = no, and mmap_disable = no. This makes performance 10% better in any situation. Our testing setup (very close to the real one) - Dell PowerEdge 2850, 2 P4 Xeon 3GHz, 3GB RAM - RHEL 4.7 (not sure about this, the last RHEL4) 32 bits - mailboxes are always in a nfs filesystem - for testing mbox file I've used dovecot-cvs.mbox I've attached a couple of graphs to show this results (I've a lot of them, but result are pretty close from one to another). Also, dovecot -n output for 1.2.6 with indexes in the NAS. Only needed changes have been applied from one conf to another. If you feel that the benchmark can be more "real" with some changes, just tell me. Also, if you are interested in the rest of graphs or date, tell me. Next week I'll be quite busy, but as soon as possible I'll test with an iSCSI disk for indexes. Aaaaaaaaaaagur. -- Joseba Torre. Vicegerencia de TICs, área de Explotación

[Dovecot] How to see if sieve is active ?
by Koenraad Lelong 30 Oct '09

30 Oct '09

Hi, I think I activated sieve, but it's doing nothing. I know manage-sieve works so I made some rules. But they do nothing. I ran sieve-test, which seems to work, but does not move the mail I test. Is this how it works ? I thought the -e parameter just "tested" the rules and did nothing and my command was supposed to do the "real thing". I read there should be a log. I don't find this, how should I enable this ? I just found that lda can have a separate log. I'll enable this and see. I read the wiki-page different times, but I don't see what I'm doing wrong. I attached some files. Sieve-test.txt is the command and output from sieve-test. Phpscript.sieve is the file .dovecot.sieve points to, and dovecot-config is my dovecot config ;-). Thanks for any pointers.

[Dovecot] dovecot-shared and shared "\Seen" flags
by Dave 29 Oct '09

29 Oct '09

(Running Dovecot 1.1.0) Is it possible to either - (a) Still have shared "\Seen" flags even while using the dovecot-shared file or (b) Indicate to Dovecot in some way other than the dovecot-shared file which permissions to use for any messages created? The problem is, in my shared folder (using symlinks) scenario I am using, I have to use the dovecot-shared file to make sure new messages get written with the correct user and group permissions so that everyone appropriate can access them, but I still would like the functionality of the shared "\Seen" flags in these shared/symlinked folders (which having dovecot-shared seems to knock out). Is it possible to do both somehow? Dave

Option (a) sounds like the cleanest solution, but a bit of testing showed that Postfix doesn't wait on deliver before replying to DATA so this seems to always result in a bounce. I've perused the postfix documentation but so far no luck; if anyone reading this has any insight on how we might configure postfix to behave this way, could you please let me know (maybe offlist would be best, as this may be considered somewhat off-topic). We are using something similar to option (b) currently, but it's not really an elegant approach and we would really like to move away from it. Option (a) sounds great, if we can somehow get it to work. TIA, Marty

[Dovecot] Question about Windows Mail for Vista IMAP client
by Stewart Dean 29 Oct '09

29 Oct '09

When TBird logs on, it does it quietly, that is it opens one or two logins. When you start working it'll open a few more. Quiet, no thrashing around When WM4Vista opens, it appears to login and disconnect (immediately) once for every folder a person has. 20 folders, 20 logins and disconnect, ripple fire. Anybody have an idea why WM4V is so busy and TB is quiet doing the same thing? I fell over this doing testing on V1.2.6 but find it's also the case back on my production V1.1.15 -- ==== Once upon a time, the Internet was a friendly, neighbors-helping-neighbors small town, and no one locked their doors. Now it's like an apartment in Bed-Stuy: you need three heavy duty pick-proof locks, one of those braces that goes from the lock to the floor, and bars on the windows.... ==== Stewart Dean, Unix System Admin, Bard College, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

[Dovecot] Wish-list: X-Delivered-To headers generated by dovecot-deliver
by Andrzej Adam Filip 29 Oct '09

29 Oct '09

Would it be sensible/"cost effective" to make dovecot-deliver generated X-Delivered-To header(s) based on command line parameter(s)? [after striping such existing headers, before consulting sieve] I need it to: a) *clearly* mark POP/IMAP account fetched by fetchmail [with fetchmail using directly dovecot-deliver in --mda option] b) cleanly implement "shared mailboxes" with MTA such as sendmail that can be easily forced to generate "one header per one recipient" [AFAIK] -- [pl>en: Andrew] Andrzej Adam Filip : anfi(a)onet.eu Order and simplification are the first steps toward mastery of a subject -- the actual enemy is the unknown. -- Thomas Mann

[Dovecot] Multiple LDAP Userdb lookups
by David 29 Oct '09

29 Oct '09

Hello one & all, I understand it is possible to do multiple lookups for userdb info of different types, for instance a local "real" account & virtual MySql lookups. Is it possible to do two separate ldap lookups to differnt parts of the same AD domain? I have a config file to do my authentication lookup against the domain. Then I have a 2nd config file for the userdb lookups which uses ldap to query our AD for their userdb info. I need to query a 2nd part of the AD for another group of users & unfortunately putting all users into one container isn't possible. So, if I add another ldap stanza to dovecot.conf will I break anything? Cheers, David. This email is confidential and is intended solely for the use of the parties to whom it is addressed.

[Dovecot] Thunderbird and Trash folder
by Stefan Onken 29 Oct '09

29 Oct '09

Hello, I have my problems with the Trash folder in thunderbird. Most of the times (it did work, but only for a short period) Thunderbird is not considering the "Trash" folder (or in my case the "Papierkorb") as the trash folder. The symbol disappears and I am not able to delete folders. Deleted emails are disappearing at all. The usual Google solutions like maildir vs. mbox doesn't help a lot, I am using maildir and the directory structure looks fine. I noticed that I have two trash folders, one with "INBOX.", one without. That may be a problem with Squirrelmail, because I am using both Thunderbird and Squirrelmail. Any idea to solve this issue with Thunderbird ? Thank you, Stonki Dovecot -a: http://www.pastebin.org/49066 Directory structure: http://www.pastebin.org/49067

[Dovecot] Multiple SSL certs question
by Jean-Baptiste Vignaud 29 Oct '09

29 Oct '09

Hello; I was reading the message "how to config dovecot for multiple domains, multiple SSL certs, and conditional IP access -- with passwd-file passdb?", and i was wondering if Dovecot could support the SNI extention of TLS ? SNI is Server Name Indication where during the TLS negotiation, the client set the name of the server it tries to reach I dont know if any imap/pop client support this yet, but this would be a great feature for one IP/multiple virtual domains. Each SNI client would have the correct certificate and not the "main/generic' one. It seems that mutt has a patch for that http://www.mail-archive.com/mutt-dev@mutt.org/msg05251.html

I run dovecot 1.2.6, before last update I had 1.2.2. on Debian Lenny. I noticed that my config directory /etc/dovecot is filled up with hundreds of old auth-worker.12345 sockets. I guess they should have been cleaned up, is there a misconfiguration? When I remember right, this did not happen with dovecot 1.1.

hi everybody, got a strange issue with 1.2.4 on SLES11. When listing the user's available subscriptions with any client, every shared mailbox that can be subscribed is listed twice, once with it's correct name, 'folder' for example. the second appereance is without the last letter of the name, 'folde' for example. strange behaviour, since this happens with any client. i hope somebody know what is wrong here. thanks in advance, hendrik -- LWsystems GmbH & Co.

[Dovecot] Dovecot
by Claudio Prono 28 Oct '09

28 Oct '09

Hello all, I use dovecot11-1.1.7-1.4.1 with OpenSuse 11.1. Everything works fine, except the vacation with managesieve. When i send a mail to an address with vacation, i recieve back a vacation message, but i read an error like this into dovecot-deliver.log: Error: file_dotlock_create(~/.dovecot.lda-dupes) failed: No such file or directory And then the vacation is send any time, without limits. I think the problem is dovecot can't find home directory for the mail to write the .dovecot.lda-dupes, but i don't know how to specify that. Here is my config: # 1.1.7: /etc/dovecot/dovecot.conf # OS: Linux 2.6.27.29-0.1-default x86_64 openSUSE 11.1 (x86_64) ext3 log_path: /var/log/dovecot-err.log info_log_path: /var/log/dovecot-inf.log protocols: imap imaps pop3 pop3s managesieve login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login login_executable(managesieve): /usr/lib/dovecot/managesieve-login first_valid_uid: 51 last_valid_uid: 51 first_valid_gid: 51 last_valid_gid: 51 mail_location: maildir:/var/mail/virtual/%d/%u mail_debug: yes mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_executable(managesieve): /usr/lib/dovecot/managesieve mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugins(managesieve): mail_plugin_dir(default): /usr/lib64/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib64/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib64/dovecot/modules/pop3 mail_plugin_dir(managesieve): /usr/lib64/dovecot/modules/managesieve imap_client_workarounds(default): outlook-idle imap_client_workarounds(imap): outlook-idle imap_client_workarounds(pop3): imap_client_workarounds(managesieve): pop3_uidl_format(default): %08Xu%08Xv pop3_uidl_format(imap): %08Xu%08Xv pop3_uidl_format(pop3): UID%u-%v pop3_uidl_format(managesieve): %08Xu%08Xv sieve_storage(default): sieve_storage(imap): sieve_storage(pop3): sieve_storage(managesieve): /var/mail/virtual/%d/%u/sieve sieve(default): sieve(imap): sieve(pop3): sieve(managesieve): /var/mail/virtual/%d/%u/.dovecot.sieve namespace: type: private prefix: INBOX. inbox: yes list: yes subscriptions: yes auth default: mechanisms: plain login passdb: driver: sql args: /etc/dovecot/dovecot-mysql.conf userdb: driver: passwd userdb: driver: sql args: /etc/dovecot/dovecot-mysql.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 plugin: quota: maildir quota: maildir:User quota quota_warning: storage=80%% /usr/bin/quota_warning.sh 80 quota_warning2: storage=90%% /usr/bin/quota_warning.sh 90 quota_warning3: storage=99%% /usr/bin/quota_warning.sh 90 sieve: /var/mail/virtual/%d/%u/.dovecot.sieve sieve_storage: /var/mail/virtual/%d/%u/sieve And this is my vacation script (generated with smartsieve): #Mail filter rules for claudio(a)mediaservice.net #Generated by claudio(a)mediaservice.net using SmartSieve 1.0.0-RC2 2009/10/26 12:34:19 require ["vacation"]; vacation :days 1 :addresses ["claudio(a)mediaservice.net"] text: sono assente . ; ##PSEUDO script start #SmartSieveRule#a:6:{s:6:"status";s:7:"ENABLED";s:7:"control";N;s:8:"matchAny";N;s:10:"conditions";a:0:{}s:7:"special";s:8:"vacation";s:7:"actions";a:1:{i:0;a:4:{s:4:"type";s:8:"vacation";s:7:"message";s:12:"sono assente";s:4:"days";s:1:"1";s:9:"addresses";a:1:{i:0;s:24:"claudio(a)mediaservice.net";}}}} #mode&&basic How i can fix this?

[Dovecot] Sieve vacation with russian subject
by Nikita Koshikov 28 Oct '09

28 Oct '09

Hello list, I have noticed that sieve vacation action breaks some non-english letters in the subject. I tested with russian language, if subject contains letters from specific diapason russian alphabet, the message received with unreadable subject, but text in the body with the same letters looks ok. Here is example of full subject header, it contains russian alphabet: Subject: абвгде�?жзийклмноп�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�? Maybe this headers will be usefull: MIME-Version: 1.0 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 8bit .dovecot.sieve file looks correct, here is it: require ["vacation"]; # rule:[test] if anyof (true) { vacation :days 1 :addresses ["user(a)domain.com"] :subject "абвгдеёжзийклмнопрстуфхцчшщъыьэюя" text: Тестовое русское сообщение(Test russian message). ; } I'm running dovecot-1.1.16 with dovecot-sieve-1.1.6 and managesieve-0.10.6. Please tell, is it possible to fix this ?

Hello All! I`m using dovecot 1.2.6 I have folder named in russian "САПП", and when in filter i wrote: fileinto "САПП"; all works well. Now i find 2 web applications to manage sieve filters (horde-ingo and squirrelmail/avelsieve) - then creates filter like this: if header :contains "Subject" "САПП" { fileinto "&BCEEEAQfBB8-"; stop; } And creates another folder ".&-BCEEEAQfBB8-", but GOOD folder name already exist ".&BCEEEAQfBB8-". Please help to understand why dovecots deliver make this happen.

[Dovecot] antispam-plugin 1.2 and trailing carriage-returns
by Karsten Bräckelmann 28 Oct '09

28 Oct '09

Guys, Dovecot 1.0.15 [1], just built the latest antispam-plugin 1.2 (tarball) for testing, mailtrain backend for SA integration. Both built from custom spec files. The mail that is being trained is different than its respective source in the mbox file. The trained one shows added, trailing carriage-return chars for all headers, which are not in the headers in the mbox file. This breaks sa-learn -- both these variations are different, and SA would learn *both* when run against each one separately. How comes? Any insight? How could I fix this, other than wrapping the sa-learn inside another shell script and have sed strip off the noise? This becomes more of an issue, once I switch from sa-learn to the lightning-fast spamc training variant. TIA guenther [1] Yes, I know, sorry. Don't want to change everything at the same time, and the target system I'm experimenting for runs that version, too. -- char *t="\10pse\0r\0dtu\0.@ghno\x4e\xc8\x79\xf4\xab\x51\x8a\x10\xf4\xf4\xc4"; main(){ char h,m=h=*t++,*x=t+2*h,c,i,l=*x,s=0; for (i=0;i<l;i++){ i%8? c<<=1: (c=*++x); c&128 && (s+=h); if (!(h>>=1)||!t[s+h]){ putchar(t[s]);h=m;s=0; }}}
