[Dovecot] BSD kqueue testing, once more before 1.0rc7
by Timo Sirainen 17 Aug '06

17 Aug '06

I did a few more changes and it seems to be working with FreeBSD. I didn't before realize that event filters weren't bitmasks so that broke things. Anyway, a bit more "real world testing" would be better than my test program and telnet localhost -tests :) I'll release 1.0rc7 in any case today before I go to sleep (so, max. 6 hours or so). http://dovecot.org/nightly/dovecot-latest.tar.gz

[Dovecot] LDAP usernames with spaces
by Tim Schafer 17 Aug '06

17 Aug '06

I'm trying to setup dovecot to work with an existing virtual user database in LDAP in order to replace courier-imap. I have users in LDAP with dn of the following form cn=Firstname Lastname,ou=company,dc=domain,dc=com and the uid attribute containes a userid of the form flastname The on disk format for an account is: /home/exim/<uid>/.maildir My first problem is that I cannot get dovecot to authenticate the existing DNs It complains: dovecot: auth(default): plain(?,ipaddress): Username contains disallowed characters I'm assuming it doesn't like the spaces. Any way around this? Also, I don't see any way to support the seperate username and userid where the username is for authentication and the userid is used for on disk pathname. Anyway to support this? Thanks in advance. -- Regards, Tim Schafer

[Dovecot] Mailbox isn't a valid mbox file (dovecot 1.0-0.beta8.2.fc5)
by FiL ＠ Kpoxa 17 Aug '06

17 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] .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
