[Dovecot] .imap.index.data Files
by Nigel Cox 17 Aug '06

17 Aug '06

Hi, We recently had a mail storm which resulted in many tens of thousands of e-mails being delivered to each of 4 users in just 5 minutes. This was quickly resolved. However, one more savvy user though he could use the webmail (squirrelmail) to delete the e-mail without downloading it. He gave up on the idea though. I, however, removed the mail directly from the server file system. The problem now is that he has a .imap.index.data file of over 250MB! I have asked him to login again and view all the directories, I even sent him another test and asked him to delete this via webmail. None of this had any effect on the file. I thought the indexes were rebuilt with the deletion of a message? Any ideas?

[Dovecot] ldap quota limitation problem
by Amadou Toure 17 Aug '06

17 Aug '06

hello, We have configured the quota enforcement folowing the link (http://wiki.dovecot.org/Quota) but we note that the global quota limitation configuration in dovecot.conf works well but not the ldap users configuration limit. For example in the casee below, we have tried to limit quota usage for some users to 1Gb but only the global quota limitation appear in the user quota. please find below config of the dovecot.conf, dovecot-ldap.conf and the ldap attributes ####################### dovecot.conf PROTOCOL IMAP mail_plugins = quota imap_quota PROTOCOL POP3 mail_plugins = quota LDA mail_plugins = cmusieve # quota PLUGIN quota = maildir:storage=256000 ######################## dovecot-ldap.conf user_attrs = uid,homeDirectory,,uid,uidNumber,gidNumber,quotaStorage=mailQuotaSize=dirsize:storage ############################# Amadou TOURE Sonatel Multimedia, 136 Sacre Coeur, Pyrotechnique, BP 21100 Dakar Tel +221-8699810.

[Dovecot] From passwd-file to Postgresql database
by Jonathan Ballet 17 Aug '06

17 Aug '06

Hello, I have a working installation of Dovecot, which use passwd-file for both users and passwords databases. My setup uses CRAM-MD5 for the authentification mechanism and the password in my passwd-file was stored encoded with HMAC-MD5. Now, I want to use Postgresql to replace those passwd-files. So I make the necessary change in my dovecot.conf file : ========================================= userdb sql { args = /etc/dovecot/dovecot-sql.conf } passdb sql { args = /etc/dovecot/dovecot-sql.conf } ========================================= In the dovecot-sql.conf file, I comment out the simplest query, and change the default_pass_scheme to HMAC-MD5 (as in my previous setup). I put my users from the passwd-file into my database, with the same user id, and the same password (starting with {HMAC-MD5}) ... ... but it fails :( The log file says to me : ========== dovecot: 2006-08-14 15:36:12 Info: auth(default): cram-md5(jon,xxx): password mismatch ========== I tried several other password schemes (DIGEST-MD5, PLAIN-MD5, PLAIN), but only PLAIN seems to work (of course, I changed the password in the database accordingly). The documentation isn't very clear about this (or I don't find it ?) : - in an "old" auth.txt, it is written that only PLAIN is supported, but I don't knwo if I can trust it ? - I've got an old dovecot-pgsql.conf (2004, maybe from dovecot 0.9x ?), which said that supported scheme are "PLAIN, PLAIN-MD5, DIGEST-MD5, and CRYPT" So, what I am doing wrong ? And what is correct (or not) in my previous search ? Regards, -- Jonathan

[Dovecot] Trying to compile again
by Greg Deputy 17 Aug '06

I'm currently running a pre 1.0 version of dovecot. Months back I tried to compile beta6, couldn't due to some mysql client libraries issues, and gave up. I'm now trying again with rc6. This is on a fedora core2 box, with postfix 2.3 and mysql 5.0. The error I'm getting when I run make is below. Any help would be greatly appreciated, thanks! I'd really like to get up to a more recent version. ..... /usr/local/mysql/lib/libmysqlclient.a(crypto_wrapper.o)(.gnu.linkonce.d.__vt _Q25yaSSL10BulkCipher+0x8): undefined reference to `__pure_virtual' /usr/local/mysql/lib/libmysqlclient.a(crypto_wrapper.o)(.gnu.linkonce.d.__vt _Q25yaSSL10BulkCipher+0xc): more undefined references to `__pure_virtual' follow /usr/local/mysql/lib/libmysqlclient.a(crypto_wrapper.o)(.gnu.linkonce.t._._Q 28TaoCrypt14RSA_PrivateKey+0x12e): In function `TaoCrypt::RSA_PrivateKey::~RSA_PrivateKey(void)': : undefined reference to `__builtin_delete' /usr/local/mysql/lib/libmysqlclient.a(log.o)(.text+0x30): In function `yaSSL::Log::~Log(void)': : undefined reference to `__builtin_delete' /usr/local/mysql/lib/libmysqlclient.a(libtaocrypt_la-algebra.o)(.gnu.linkonc e.d.__vt_Q28TaoCrypt23AbstractEuclideanDomain+0xc): undefined reference to `__pure_virtual' /usr/local/mysql/lib/libmysqlclient.a(libtaocrypt_la-algebra.o)(.gnu.linkonc e.d.__vt_Q28TaoCrypt23AbstractEuclideanDomain+0x10): undefined reference to `__pure_virtual' /usr/local/mysql/lib/libmysqlclient.a(libtaocrypt_la-algebra.o)(.gnu.linkonc e.d.__vt_Q28TaoCrypt23AbstractEuclideanDomain+0x14): undefined reference to `__pure_virtual' /usr/local/mysql/lib/libmysqlclient.a(libtaocrypt_la-algebra.o)(.gnu.linkonc e.d.__vt_Q28TaoCrypt23AbstractEuclideanDomain+0x18): undefined reference to `__pure_virtual' /usr/local/mysql/lib/libmysqlclient.a(libtaocrypt_la-algebra.o)(.gnu.linkonc e.d.__vt_Q28TaoCrypt23AbstractEuclideanDomain+0x3c): undefined reference to `__pure_virtual' /usr/local/mysql/lib/libmysqlclient.a(libtaocrypt_la-algebra.o)(.gnu.linkonc e.d.__vt_Q28TaoCrypt23AbstractEuclideanDomain+0x40): more undefined references to `__pure_virtual' follow /usr/local/mysql/lib/libmysqlclient.a(libtaocrypt_la-file.o)(.text+0x88): In function `TaoCrypt::FileSource::~FileSource(void)': : undefined reference to `__builtin_delete' /usr/local/mysql/lib/libmysqlclient.a(libtaocrypt_la-file.o)(.text+0x28c): In function `TaoCrypt::FileSink::~FileSink(void)': : undefined reference to `__builtin_delete' collect2: ld returned 1 exit status make[3]: *** [dovecot-auth] Error 1 make[3]: Leaving directory `/root/dovecot-1.0.rc6/src/auth' make[2]: *** [all-recursive] Error 1 make[2]: Leaving directory `/root/dovecot-1.0.rc6/src' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/root/dovecot-1.0.rc6' make: *** [all] Error 2

[Dovecot] Mailbox isn't a valid mbox file (dovecot 1.0-0.beta8.2.fc5)
by Dmitry Filonov 16 Aug '06

16 Aug '06

Hello, I have upgraded my dovecot-0.99.13-3.FC3 to dovecot-1.0-0.beta8.2.fc5 recently and now am having weird problem. If somebody's mailbox has the first line in a form of From "User Name" <user(a)host.domain.edu> Thu Oct 7 14:20:00 1999 instead of From user(a)host.domain.edu Thu Oct 7 14:20:00 1999 then that mailbox couldn't be precessed by dovecot. It wasn't a problem with 0.99.13, but it is a problem with 1.0. Is there any fix for that on a dovecot's side? I don't like the idea of going through all 100Gb of mailboxes and fixing the From line. Thank you, FiL

[Dovecot] Port Change?
by Charlie Davis 16 Aug '06

16 Aug '06

Hey all, Got a super simple question that I can't find an answer to on google or on the list. I want dovecot to listen to port 143 and another port as well for imap. Is this possible? The dovecot.conf has a little note that says "If you want to specify ports # for each service, you will need to configure these settings inside the # protocol imap/pop3 { ... } section, so you can specify different ports # for IMAP/POP3." but in the protocol section for imap, I don't see any example or what not of changing the port. Any help? -Charlie

[Dovecot] Authentication Failure
by William J. Dzieciolowski 16 Aug '06

16 Aug '06

Probably a newbie question.... sorry. Did a deluser a week or so ago, but didn't remove any of the users files. I re-enabled the user via useradd with the -u and set the uid the same as it was before. Now when I try and log the user into his mail via Thunderbird, /var/log/messages reports dovecot(pam_unix)[17259]: authentication failure; logname= uid=0 euid=0 tty= ruser= rhost= user=sean Any help is appreciated. Thanks.

[Dovecot] dovecot 1.0rc6 and LDAP problem
