[Dovecot] Problems in auth when switching from PLAIN-MD5
by Eduardo Casarero 03 Jun '11

03 Jun '11

Hi, i am running dovecot 2.0.11 (with mysql backend) and until now using PLAIN-MD5 as pass default_pass_scheme everything was working fine. 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

[Dovecot] passdb: password contains illegal chars question

Hi, some question about passdb backend: I'll receive this (using dovecot 2.0.13, pgsql passdb backend) for some users: mail dovecot: auth: passdb(account-username,127.0.0.1): Attempted login with password having illegal chars Password schema ist crypt-md5. So what "chars" does dovecot not like (why?) and whats the preferred way to fix this? regards Torsten -- Bitte senden Sie mir keine Word- oder PowerPoint-Anhänge.

[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. Output of dovecot -n is below The only possible difference I can find between this and the previous install of the SAME distro/dovecot package is that this time I use ext4 filesystem. Maybe, I don't remember, I was using ext3 in the original install. What must I change to gain access again to my mailboxes??? thanks!

[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
