[Dovecot] Fixing bad maildir message sizes
by Richard Platel 23 Jan '13

23 Jan '13

Hello. As stated in my previous message, we have some old compressed maildir messages with incorrect sizes in the filename. These messages cause dovecot 2.x problems. I'm trying to write a script to crawl all our messages, check the actual message size and if necessary, fix the filename. However, when I do this, dovecot gives the message a new UID on next login. If I change the filename in dovecot-uidlist, dovecot still gives a new UID on next login. If I change dovecot-uidlist and delete the index, then the UID is preserved. Re-indexing our millions of mailboxes is not a great solution for us. Is there a good way to fix this?

[Dovecot] question on "doveadm user" and pass/userdb
by Gábor Lénárt 22 Jan '13

22 Jan '13

Hi, I'm about getting to know dovecot in details, I am about the command "doveadm user". The man page shows this example: userdb: jane uid : 8001 gid : 8001 home : /home/jane mail : sdbox:~/sdbox plugins : sieve quota_rule: *:storage=150M It seems to be nice, however I never got this only: ~# doveadm user lgb@office userdb: lgb@office That's all. The dovecot test configuration works otherwise via IMAP/POP3/LMTP nicely. What I guess that the lack of extra information (which would be needed by some scripts of mine, eg for getting user's home easily from shell scripts, as it's hash based, etc) is caused because I don't pass home (and/or other settings) back from userdb and/or passdb. However I do have these in global scope: mail_home = /mailstorage/%Ld/%Ln (yes, this is not hashed at all at the momement but it will be soon) mail_location = maildir:~/Maildir mail_uid = vmail mail_gid = vmail (... and also some global quota stuffs configured in plugin section) Now, I am a bit confused: even with passdb/userdb does not return with user home or GID/UID, dovecot knows these in case of pop3/imap/lmtp access, since these information can be "composed" from those settings. But then, wouldn't it possible so "doveadm user" shows those as well, like lmtp/pop3/imap can resolve those too? Honestly, it's a bit redundant to put needed information into user and pass attrs in every dbs (I have some) when dovecot knows those otherwise ... If I interpret "doveadm user"'s goal wrong (it's just for userdb/passdb query tool nothing more), is there any tool which works in this config, displaying extra information (at least user's home), or should I create some script which just repeats the functionality of dovecot's configured mail_home resolution? Thanks.

Hello, i'm trying to search in mails which are in russian language. Search works fine for UTF-8 mails, but it ignores KOI8-R ones. For english in any mails it also works fine. How i can solve it?

[Dovecot] Mail logger question
by Hungerburg 21 Jan '13

21 Jan '13

I use Dovecot simply as a way, to provide an e-mail archive for people on the LAN, where they can move messages into from within thunderbird. Mails are stored in a maildir of one system user where all the people know the password of. This was very easy to setup in ubuntu 12. Today I started using the mail_log plugin to provide an audit trail. Now I am looking for a light way, to get the log reflect the different people or principals. One way is, to create users with the same ID in the passwd and shadow files, but I'd rather have them in a separate file, something like a list of aliases for the system user. Can you suggest a simple way, without going virtual users? Below the relevant info on dovecot: $ dovecot --version 2.0.19 $ dovecot -n # 2.0.19: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-35-generic x86_64 Ubuntu 12.04.1 LTS mail_plugins = " fts fts_squat mail_log notify" passdb { driver = pam } plugin { fts = squat fts_squat = partial=4 full=10 mail_log_events = save delete undelete expunge copy mailbox_delete mailbox_rename mail_log_fields = uid box msgid size from subject } protocols = " imap" ssl_cert = </etc/ssl/certs/ssl-cert-snakeoil.pem ssl_key = </etc/ssl/private/ssl-cert-snakeoil.key userdb { driver = passwd } Thank you all -- peter

[Dovecot] %d in configuration file does not work
by Jens Tobiska 19 Jan '13

19 Jan '13

I am trying to set up dovecot in a postfix virtual account/domains setting. In the configuration file I would like to use %d in two places, for: mail_location = /var/mail/vhosts/%d/%n and to specify the location of the respective passwd file: passdb passwd-file { args = /etc/auth/%d/shadow } Looking at the logs, %d is empty while %n works, so dovecot is looking for something in /var/mail/vhosts//myname and /etc/auth//shadow which don't exist. Replacing %d in dovecot.conf with the actual domain name works. So, the quesiton is, why is %d empty, and from where does it take its value?

[Dovecot] [PATCH] LMTP: Permit user IDs containing recipient_delimiter
by Ulrich Zehl 18 Jan '13

18 Jan '13

The Dovecot 2.1 LMTP server currently always strips the address extension from a recipient address (if recipient_delimiter is set), meaning user IDs cannot contain the recipient delimiter character, e.g. "user+foo" is not supported. This was surprising for me, as Postfix behaves differently in this regard: It first looks up "user+foo", and only then "user". The attached patch works for me and brings Dovecot's behavior in line with Postfix. Please let me know what you think about it.

[Dovecot] users = virual + system (both with ldap backend) => Fatal: setgid(12(mail)) failed with euid=501(...
by lejeczek 18 Jan '13

dear all probably something trivial, just cannot get my way around it, my goal is to get sieve on local-system users too, so postfix hands lda over to dovecot errors with mail for system users: lda(me): Fatal: setgid(12(mail)) failed with euid=501(me), gid=513(Domain Users), egid=513( Domain Users): Operation not permitted (This binary should probably be called with process group set to 12(mail) instead of 513(Doma in Users)) mail storage is in users' homes and these are on nfs3 which bits am I missing, please advise? regards

[Dovecot] possible: two private namespaces with different quota?
by Steffen Kaiser 17 Jan '13

17 Jan '13

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, in thread "how to setup different quota for multiple namespaces" I tried to get an additional, private namespace "archive" with yet another quota. Every message, regardless if delivered to INBOX or archive, counts for both namespaces, the default one and the archive one. Furthermore the dict records the quota of the archive namespace as user "ns=archive". Because the quota_rules does not accept "*", I see no way to have two or more private quota roots. Could one improve quota_root_rule_find(struct quota_root_settings *root_set, const char *name) { struct quota_rule *rule; array_foreach_modifiable(&root_set->rules, rule) { char *p = strchr(rule->mailbox_name, '\0'); if(p && p > rule->mailbox_name + 1 && p[-1] == '*' ) { /* compare box* */ if(memcmp(rule->mailbox_name, name, p - rule->mailbox_name - 2) == 0) return rule; } else if (strcmp(rule->mailbox_name, name) == 0) return rule; } return NULL; } So one could add a relative rule for the default private namespace.

[Dovecot] Benchmarking: Dovecot vs Courier. Courier wins as POP3 server
by Alexandr Sabitov 17 Jan '13

17 Jan '13

Hi All, I have compared Dovecot performance to Courier and it appears that as a POP3 server Dovecot is slower in 2 times but as an IMAP server it is faster in 1.5 times. The same node (16CPUs), testing time is 30 min, please see results and dovecot configs attached. Benchmark software is MStone used by Sendmail Inc so is is quite reliable. I do not see anything else to tweak in Dovecot to increase POP3 performance. Can we all have some tips to improve it please ?

[Dovecot] dovecot-2.2.beta1: do not removes e-mail with enabled replication
by Евгений Басов 16 Jan '13

Hello. I'm created two installations of dovecot-2.2.beta1 with identical config. Without replication each server works good. With replication enabled every changes are replicated between these ones. When I probe remove or move some email in another folder it is disappears and reappears again and again in source folder and appears in destination folder.

by Erik Colson 16 Jan '13

16 Jan '13

Hi I'm currently using dovecot 2.0 with squat fts which does a nice job. However I'm thinking about upgrading to dovecot 2.1 and the wiki isn't clear about which fts can or should be used with it. Is squat support dead ? As the wiki mentions that the config syntax is obsolete, I'm not sure if squat is obsolete also ? If not, what is the new syntax ? But in the case squat is dead.. what is the recommended alternative nowadays ? I don't really need substring search, but it is a nice thing to have. PS : I will be using dovecot 2.1 with maildir thanks -- erik

[Dovecot] Dovecot subtree problem in ldap/ad search
by Marcus Jüttner 15 Jan '13

15 Jan '13

Hallo Im trying to set up an Postfix and Dovecot mailserver with ActiveDirectory interation. Postfix is doing well and even Dovecot does ... but I have one big problem! My AD Accounts ar stored in two Subfolders ou=Bischoff Benutzer LTT, dc=bischoff-ltt, dc=local ou=Bischoff Benutzer Nbg, dc=bischoff-ltt, dc=local If i use "base = ou=Bischoff Benutzer LTT, dc=bischoff-ltt, dc=local" everything is fine but users from "ou=Bischoff Benutzer Nbg" will not work. Thats ok so far. But when i use "base = dc=bischoff-ltt, dc=local" none user will be found even if i use "scope = subtree". Postfix has no problem with the base set to "dc=bischoff-ltt, dc=local". Ldapsearch has no problem too. I use Version 2.1.12 on Gentoo Linux with a 2003R2 AD Is scope=subtree broken in Dovecot? Must I set some special parameters for Windows AD? My Config: hosts = 192.168.1.98 dn = bischoff-ltt\ldapsearch dnpass = xxxxx auth_bind = yes ldap_version = 3 scope = subtree base = dc=bischoff-ltt, dc=local #base = ou=Bischoff Benutzer LTT, dc=bischoff-ltt, dc=local #base = ou=Bischoff Benutzer Nbg, dc=bischoff-ltt, dc=local user_attrs = =home=/var/dovecot/%Ln/,=mail=maildir:/var/dovecot/%Ln/ user_filter = (&(ObjectClass=person)(sAMAccountName=%u)) pass_filter = (&(ObjectClass=person)(sAMAccountName=%u)) Thanks for Help Marcus

[Dovecot] Define custom ldap libraries when building Dovecot
by Nikolaos Milas 15 Jan '13

15 Jan '13

Hello, I would like to compile Dovecot using custom ldap libraries, located at a particular custom system location. How should I alter the config process to specify that the include dir is "/usr/local/openldap/include" and the lib dir is "/usr/local/openldap/lib64" and not the standard ones (/usr/include/ and /usr/lib64/ respectively) on RHEL/CentOS 5 (x86_64). Note that all of the above files/folders exist on the file system at the same time. The idea is to build dovecot against current openldap v2.4.x libraries and not against the available (by the OS) ancient openldap v.2.3.x libs. Please, advise. Thanks, Nick

[Dovecot] Zlib maildir reindex bug?
by Richard Platel 14 Jan '13

14 Jan '13

Hi Running dovecot 2.1.7 (from debian repo). We have some old compressed maildir messages with the wrong S= size in the filename (our fault). If I delete index files, log in to the mailbox and try to FETCH the bad message, dovecot complains about the incorrect message size, attempts to fix the filename and disconnects the client. However, it changes the filesize to the size of the message on disk, not the message's uncompressed size. For subsequent clients, the FETCH works, but dovecot logs an error (and maybe re-indexes the mailbox?) and the message UID changes.

Any other hints? If the UIDs are just headers, why don't you simply checksum without them: sed -e '/^Whatever-header:/d' < $file | md5sum grep -Ev '^Whatever-header:' < $file | md5sum Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] sieve reject to wrong address?
by Felix Rubio Dalmau 14 Jan '13

14 Jan '13

Hi all, I have succeed in setting up postfix (to send/receive emails), dovecot to access the folders via IMAP, all using TLS and sieve under dovecot to manage filters. I have also set up a sieve rule to reject those mails whose size exceeds 2 MB... and I'm really proud of everything, because it is my first time!! However, when rejecting the mail, instead of sending a mail saying "I'm sorry blah, blah, blah" to the originary sender, it is sent to the final recipient (that is, me). Do you know how to solve it? Is it a problem from sieve or dovecot? I think is some misconfiguration of my dovecot installation, because the sieve rule is: ################ if size :over 2M { reject text: Ho sento, no accepto cap correu de mes de 2MB de tamany. Sisplau, puja els fitxers mes grans a un servidor i envia'm un link. Gracies. I'm sorry, I do not accept mail over 2 MB in size. Please upload larger files to a server and send me a link. Thanks. . ; } ################ dovecot log looks like: Jan 14 17:34:16 server dovecot: lda(felix@server): sieve: msgid=<201301141734.16203.felix@server>: rejected message from <felix@server> (reject) Jan 14 17:34:16 server postfix/cleanup[2011]: 2B59CB59: message- id=<dovecot-1358181256-51155-0@server> Jan 14 17:34:16 server postfix/pipe[2012]: 311AF4E0: to=<felix@server>, relay=dovecot, delay=1, delays=0.81/0.02/0/0.19, dsn=2.0.0, status=sent (delivered via dovecot service) Thank you! -- Felix Rubio Dalmau

Hello, Due to a misstake I got many duplicate emails in my inbox folder. They are stored in maildir format, so my initial thought was do simply md5sum the mail files and remove the duplicates. This doesnt work because the mails has differinf uids. Any other hints? -- Joakim Verona

[Dovecot] Dovecot SASL Client support?
by Charles Marcus 14 Jan '13

14 Jan '13

Hi all, I seem to recall mention of SASL client support either being added, but can't remember for sure. The wiki says nothing about Client support (now, or in the future)... http://wiki2.dovecot.org/Sasl So - is there support for it now? If not, is it planned for anytime soon? Thanks, -- Best regards, Charles
