[Dovecot] Dovecot auth problem on FreeBSD 4.10
by Viren Patel 22 Jul '04

22 Jul '04

Hello. I am trying to setup Dovecot on an Alpha running FreeBSD 4.10. I am simply trying the imap/pop3 protocols at this time. But with both protocols the log message I get is: pop3-login: fd_send(5) failed: Bad file descriptor dovecot: child 275 (login) returned error 89 or imap-login: fd_send(5) failed: Bad file descriptor dovecot: child 275 (login) returned error 89 I have tried various combinations of: auth = default|plain|pam auth_userdb = passwd auth_passdb = passwd|shadow|pam|passwd-file but nothing works. What am I doing wrong? Thanks. Viren Patel University of Texas at Austin

[Dovecot] One final issue
by Tom Ray [Lists] 22 Jul '04

22 Jul '04

Timo- Thanks for all the help. After I changed the permissions to the virtual user I setup I had a few small issues but was able to work through them. Now IMAP is running great. But my new question is, do I need to do anything to get it to work with POP? My server refuses to respond on 110 and I'm wondering if there is something I need to do? I was under the impression that Dovecot can handle both POP/IMAP requests. TIA Tom

[Dovecot] Authentification with PostgreSQL
by Felix.Schwarz＠web.de 22 Jul '04

22 Jul '04

Hi all, I found Dag Wieers' Fedora Core 2 rpm on http://dag.wieers.com/packages/dovecot/ and installed it. Now dovecot-auth isn't complaining anymore about an unknown userdb type but I can't get authentication working. /etc/dovecot.conf (...) # Authentication process name. auth = default # plain digest-md5 anonymous auth_mechanisms = plain auth_userdb = pgsql /etc/dovecot-pgsql.conf auth_userdb = pgsql /etc/dovecot-pgsql.conf auth_user = root auth_verbose = yes (...) /etc/dovecot-pgsql.conf connect = host=localhost dbname=xams-dovecot user=dovecot password=hallo default_pass_scheme = PLAIN password_query = SELECT password FROM users WHERE username = '%u' user_query = SELECT home, uid, gid FROM users WHERE username = '%u' If I try to login over imap (no ssl) with Mozilla Mail, authentification will always fail (username: felix(a)schwarz-online.org, password: "hallo"). /var/log/syslog Jul 22 15:48:47 steinchen postgres[2057]: [30-1] DEBUG: forked new backend, pid=2198 socket=10 Jul 22 15:48:47 steinchen postgres[2198]: [31-1] DEBUG: Passwortpaket erhalten Jul 22 15:48:47 steinchen postgres[2198]: [32-1] LOG: Verbindung authorisiert: Benutzer=dovecot Datenbank=xams-dovecot (...)

Password encryption? Is there a possibility to see what dovecot gets from Mozilla and what are the expected results of the sql queries? I am stuck as I don't know exactely why authentification failes... thanks for your help -- Felix

[Dovecot] [PATCH] POP3 CAPA command RFC violation
by Andrey Panin 22 Jul '04

22 Jul '04

Hello, looks like SASL capability reported by dovecot in response to POP3 CAPA command doesn't conforms with rfc2449 which says: Examples: C: CAPA S: +OK Capability list follows S: TOP S: USER S: SASL CRAM-MD5 KERBEROS_V4 S: RESP-CODES S: LOGIN-DELAY 900 S: PIPELINING S: EXPIRE 60 S: UIDL S: IMPLEMENTATION Shlemazle-Plotz-v302 S: . And later: The POP3 AUTH command [POP-AUTH] permits the use of [SASL] authentication mechanisms with POP3. The SASL capability indicates that the AUTH command is available and that it supports an optional base64 encoded second argument for an initial client response as described in the SASL specification. The argument to the SASL capability is a space separated list of SASL mechanisms which are supported. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Dovecot sends SASL capability as list of AUTH=FOO pairs. Looks like copy-paste from IMAP code. Patch attached. Best regards. -- Andrey Panin | Linux and UNIX system administrator pazke(a)donpac.ru | PGP key: wwwkeys.pgp.net

[Dovecot] namespaces and behaviour of LIST and SELECT with leading ~
by Tim Southerwood 21 Jul '04

21 Jul '04

Hi One weirdness when going through the code: (We are migrating from WU-IMAP and have users with a mixture of ~/IMAP/ and ~/Mail/ for storing mail - but all user INBOX=~/.email thankfully. IMAP client config is even more random and we have 1800 users. I have been playing with namespaces to translate various prefixes ala: default_mail_env = mbox:%h/:INBOX=%h/.email:INDEX=/var/cache/dovecot/%n # Note lack of IMAP ^^^ (So clients can use ~/IMAP or ~/Mail - we have a # historic mixture) full_filesystem_access = no namespace private { separator = / inbox = yes prefix = hidden = no location = mbox:.email } namespace private { separator = / prefix = hidden = no location = mbox:IMAP/ } namespace private { separator = / prefix = IMAP/ hidden = no location = mbox:IMAP/ } namespace private { separator = / prefix = ~/IMAP/ hidden = no location = mbox:IMAP/ } User tstest has INBOX in ~/.email and mail folders in ~/IMAP/ all in mbox format: Here's a sample conversation: * OK dovecot ready. 1 login tstest ******* 1 OK Logged in. 1 list "" % * LIST (\NoInferiors \UnMarked) "/" INBOX * LIST (\NoInferiors) "/" "Trash" * LIST (\NoInferiors) "/" "Queue" * LIST (\NoInferiors) "/" "Sent" * LIST (\NoInferiors) "/" "Drafts" * LIST (\NoInferiors) "/" "Blah" 1 OK List completed. Good 1 list "" IMAP/% * LIST (\NoInferiors) "/" "IMAP/Trash" * LIST (\NoInferiors) "/" "IMAP/Queue" * LIST (\NoInferiors) "/" "IMAP/Sent" * LIST (\NoInferiors) "/" "IMAP/Drafts" * LIST (\NoInferiors) "/" "IMAP/Blah" 1 OK List completed. Good 1 list "" ~/IMAP/% 1 OK List completed. Oops (being caught by mbox_is_valid_mask as prefix begins with ~ and the client supplied prefix is being tested, not the virtual one after namespace prefix substitution) But... 1 select Blah * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted.* 5 EXISTS * 0 RECENT * OK [UNSEEN 1] First unseen. * OK [UIDVALIDITY 1090326264] UIDs valid * OK [UIDNEXT 6] Predicted next UID 1 OK [READ-WRITE] Select completed. Yes 1 select IMAP/Blah * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted.* 5 EXISTS * 0 RECENT * OK [UNSEEN 1] First unseen. * OK [UIDVALIDITY 1090326264] UIDs valid * OK [UIDNEXT 6] Predicted next UID 1 OK [READ-WRITE] Select completed. Yes 1 select ~/IMAP/Blah * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted.* 5 EXISTS * 0 RECENT * OK [UNSEEN 1] First unseen. * OK [UIDVALIDITY 1090326264] UIDs valid * OK [UIDNEXT 6] Predicted next UID 1 OK [READ-WRITE] Select completed. Oo - this works despite the ~ I would argue that with namespace {} directives, the behaviour of SELECT is correct. I would suggest that it may be better to test the final translated path thus: if full_filesystem_access = yes let anything go. else make sure that final translated mail path is identical OR a subpath of the default_mail_env mbox folder path. (INBOX is a special case and can be matched as well) This is a suggestion - what do you think? I'd have a go myself but I don't yet feel competant with the dovecot code. Best wishes Tim -- Tim J Southerwood

[Dovecot] dovecot-1.0-test27 crash on FETCH
by Wouter Van Hemel 21 Jul '04

21 Jul '04

Hello, I've got a crash with -test27 on a FETCH, just after logging in. Attached are the mailbox (1 message only), logs, sniffed session, testcase and core dump backtrace. If the dovecot.conf is needed, just ask (it's pretty much the default configuration). Maybe this has just been fixed in -test28, in which case you can just delete this email. :) Btw, it's rather irrelevant, but does anybody know a good way to read the qmail alias user's mailbox remotely (imap? The only way seems by assigning a password to the account... Regards, wouter

[Dovecot] Fatal: Unknown userdb type 'pgsql'
by felix.schwarz＠web.de 21 Jul '04

21 Jul '04

Hello, I'm trying to use postgres authentication with dovecot on a linux system running Fedora Core 2. Installation of dovecot was done by installing the rpm included in the fedora distribution ("yum install dovecot"). from /etc/dovecot.conf auth_userdb = pgsql /etc/dovecot-pgsql.conf auth_passdb = pgsql /etc/dovecot-pgsql.conf but the logs tell me: dovecot: Jul 21 19:28:39 Info: Dovecot starting up dovecot-auth: Jul 21 19:28:40 Fatal: Unknown userdb type 'pgsql' dovecot: Jul 21 19:28:40 Error: Auth process died too early - shutting down dovecot: Jul 21 19:28:40 Error: child 5229 (auth) returned error 89 imap-login: Jul 21 19:28:40 Fatal: fd_send(-1) failed: Broken pipe imap-login: Jul 21 19:28:40 Fatal: fd_send(-1) failed: Broken pipe I think that the fedora rpm was compiled without postgresql support. - Is the information given above sufficient for an educated guess? - Would that lead to the above error message? - What other errors may cause this behavior? - How can I check which authentification types are supported by my dovecot-auth? - Are there any other Fedora rpms compiled with postgres support available on the net? thank you for your help :-) -- Felix

RE: [Dovecot] Probably a bad idea but.....
by Mark Lidstone 21 Jul '04

21 Jul '04

Hi everyone, Just done some testing and thought I'd share the results. I've successfully moved a few test emails from a Mercury/32 Windows server to Maildirs. I created an IMAP folder for each user ".INBOX.Old\ Mail" and put the email in there. It's accessable via IMAP but does not show up as a new email when the user uses POP3 to collect their email - exactly what I was after (they're all using POP3 at the moment, but I will be pushing them to move to IMAP at a later date). I'm going to copy the rest of the email in one go overnight so if you don't get another email from me on here assume it worked. Thanks for the help Timo.

You'll lose message flags, but as long as the filenames don't contain ':' characters you can just copy them.
