[Dovecot] dovecot failing to chdir in home
by Stefano Maffulli 20 Oct '04

20 Oct '04

Hi all, I have been fiddling with dovecot and things seem to be stuck on this problem: Oct 20 11:21:35 mail dovecot: chdir(studiosala.net/federico/) failed with uid 1001: Permission denied Oct 20 11:21:35 mail dovecot: child 22150 (pop3) returned error 89 This is the telnet session that generates it: mail:~# telnet localhost pop3 Trying 127.0.0.1... Connected to localhost.localdomain. Escape character is '^]'. +OK dovecot ready. user federico(a)studiosala.net +OK pass XXXXXX +OK Logged in. Connection closed by foreign host. I am stuck: the UID/GID that postfix uses for dropping the mail in /varm/mail/domains/ is 1001/1001. The query string to mysql (the backend where I have stored the users) is (from mysql log, so it is executed): 682 Query SELECT 1001 AS uid, 1001 AS gid, '/var/mail/domains/' AS mail, maildir AS home FROM mailbox WHERE username = 'ale(a)studiosala.net' mail:/etc# ls -lad /var/mail drwxrwsr-t 3 root mail 4096 2004-10-19 23:49 /var/mail mail:/etc# ls -lad /var/mail/domains/ drwxr-sr-t 4 vmail vmail 4096 2004-10-20 07:03 /var/mail/domains/ I am not sure of how to proceed from here, any hint appreciated. thanks stef

[Dovecot] default_mail_env problems
by Neil Marjoram 20 Oct '04

20 Oct '04

sorry if this mail is a duplicate - I am testing the new mail system! I am having problems setting the default mail environment.# I am using Fedora Core 2 with version dovecot-0.99.10.5-0.FC2 My users all have an NFS mounted home directory, and all mail is delivered to ~Mail/.mailbox it is all mbox format. I would like to put the indexes on the local system in /var/indexes/{username}. So I set these parameters for default_mail_env : mbox:~/Mail/:INBOX=~/Mail/.mailbox Which produced the error : imap(test): stat() failed with mbox file ~/Mail/.mailbox: No such file or directory I set the mail environment back to default, linked inbox to .mailbox in the ~/Mail directory and all worked fine. Is there a better way to do this ? I would like to put the indexes on the local system in /var/indexes/{username}, so I decided to set: default_mail_env = INDEX=/var/indexes/%d/%n and got this error: imap(test): Failed to create storage with data: INDEX=/var/indexes//test dovecot: child 9142 (imap) returned error 89 I also tried : default_mail_env = INDEX=/var/indexes/%u And got the same error. I guessed at permissions, so I tried changing the ownership to dovecot and then test and then root and then 777, but I still get this error. Can anyone tell me where I am going wrong? Many thanks, Neil. -- Neil Marjoram. Systems Manager University College London Adastral Park Campus Martlesham Heath Ipswich Suffolk IP5 3RL 01473 663711

[Dovecot] Occasional error msgs from 1.0-test49
by Gregory Bond 20 Oct '04

20 Oct '04

I'm running 1.0-test49 on Solaris 2.8. MUA is Thunderbird (or mutt) running on FreeBSD. I'm using Maildir boxes. Occasionally, when browsing new mail in INBOX, I get an error back from the imapd, displayed in Thunderbird as the following popup msg: The current command did not succeed. The mail server responded: Error in IMAP command UID: Invalid BODY[..] parameter: Missing '>' in '<36864,-34800>'. >From this point, nothing much works reliably until I quit the MUA and start again. Sometimes, if I keep working, the email that was being fetched is shown but is corrupted and the msg body contains another copy of the whole email (header & body), sometimes 2 extra copies. Nothing is in the maillog. This _didn't_ happen with 0.99.

[Dovecot] 1.0-test49 FD leak
by Gregory Bond 19 Oct '04

19 Oct '04

I'm running 1.0-test49 on Solaris 2.8. The good news is that this version fixes my problem with corrupted index files (so far). The bad news is it seems to be leaking FDs to do with inbox: imap 10198 gnb 156r VDIR 255,7032 8192 5784160 /home/gnb/Maildir/new imap 10198 gnb 157r VDIR 255,7032 1093632 2917923 /home/gnb/Maildir/cur imap 10198 gnb 158r VDIR 255,7032 8192 5784160 /home/gnb/Maildir/new imap 10198 gnb 159r VDIR 255,7032 1093632 2917923 /home/gnb/Maildir/cur imap 10198 gnb 160r VDIR 255,7032 8192 5784160 /home/gnb/Maildir/new imap 10198 gnb 161r VDIR 255,7032 1093632 2917923 /home/gnb/Maildir/cur imap 10198 gnb 162r VDIR 255,7032 8192 5784160 /home/gnb/Maildir/new imap 10198 gnb 163r VDIR 255,7032 1093632 2917923 /home/gnb/Maildir/cur imap 10198 gnb 164r VDIR 255,7032 8192 5784160 /home/gnb/Maildir/new imap 10198 gnb 165r VDIR 255,7032 1093632 2917923 /home/gnb/Maildir/cur (seems to be a new pair of FDs leaked each time my MUA checks for new mail).

[Dovecot] Index corruption
by Gregory Bond 18 Oct '04

18 Oct '04

I'm getting pretty constant index corruption on (admittedly large) Maildir folders. I'm running Thunderbird 0.7.3 and Mutt as my IMAP clients (on FreeBSD). Server is Dovecot 0.99.10.9 configured thusly: ./configure --disable-ipv6 CC=gcc-3.3 CXX=g++-3.3 --prefix=/opt/dovecot --without-pop3d on a Solaris 2.8 box. Maildirs are NFS-mounted, but the index files are on local UFS filesystem: default_mail_env = maildir:~/Maildir:INDEX=/export/01/imapd/%u MTA is Postfix, LDA is procmail delivering to several Maildir folders. There will be 2 (or more) dovecot instances running for this user (me) - several from Thunderbird and one from the BIFF client (icewm). Turning off the BIFF client doesn't seem to help. Symptoms: when using Thunderbird, and deleting a msg or moving it to another folder, Thunderbird will sometimes not display the next unread message, but just sit there. Changing folders works, but changing back to the previous folder (or quitting/restarting Thunderbird) only shows the first N messages (N is about 500, in a Maildir of about 6000, and it is the SAME email that is "last" every time.) This happens with multiple folders, but (usually) only folders that are delivered to by procmail (this may be related to the problem or a coincidence in that only those folders have unread email!) Accessing the mailboxes using MUTT via IMAP shows the same truncated message list. (I'm the only user using dovecot as I want Maildir, the other users have uw-imap, so dovecot is listening on port 4343) Closing all imap clients, then removing the .index.* files from the appropriate /export/01/imapd/ directory, then restarting the imap client causes the missing messages to reappear (after a suitable wait for the index files to be recreated). It really looks like locking or truncation issues in the index files.... Any clues? Debugging hints? This is happening several times per day so I can get lots o' debug data! Greg.

[Dovecot] test49 Authenticate PLAIN disabled stops pop3s

18 Oct '04

Unlike test47, test49 refuses to authenticate pop3s if disable_plaintext_auth = yes Checked the crypto with: snort -vde tcp port 995 The connection is being made with ssl so it looks like the plaintext auth preventer is broken. -kim __________________________________________________ Do You Yahoo!?

[Dovecot] UIDL bug
by dovecot＠spam.turbolink.net 16 Oct '04

16 Oct '04

I noticed a problem with handling UIDL msgnumber in test46. If you do "UIDL 1" on a POP3 connection it returns the UID of the message followed by a dot and an error message. I made 2 changes: I added the following line to line 527 of src/pop3/commands.c ctx->message = message; I changed line 559 from: if (list_uids_iter(client, ctx)) to: if (!list_uids_iter(client, ctx)) Next time I'll submit an actual diff, I've made lots of other changes and comments in my source though so it's harder. - Mike

[Dovecot] 1.0-test49
by Timo Sirainen 16 Oct '04

16 Oct '04

http://dovecot.org/test/ Fixes the extra data appearing in POP3 mails (and possibly some other random problems). Created lib-sql API with asynchronous PostgreSQL and synchronous MySQL implementations. Also means I dropped mysql and pgsql userdb and passdb and replaced them with one generic sql userdb and passdb. If you were using the old ones, you'll have to fix your configuration. See included doc/dovecot-sql.conf for more information. Note that the password_query must now return "password" named column, before it was assumed that the first returned column was password.

[Dovecot] 1.0-test48
by Timo Sirainen 15 Oct '04

15 Oct '04

http://dovecot.org/test/ - dovecot-auth talks now ASCII based protocol. this makes it easy to write complete replacement auth server if someone wants to do something weird. I also thought maybe Postfix could be made to talk that (or similiar) protocol as well, but no-one has answered my mail about it so far. Perhaps I should just write binary compatible libsasl2 which actually talks to dovecot-auth. - other authentication code cleanups - don't insert extra spaces at the beginning of FETCH replies (I guess most clients ignored them) - mbox fixes - some index fixes - Hopefully fixes _send_istream() assert crash with FreeBSD (sendfile() was used wrong) The authentication code changes haven't been tested too much. I only tried that PLAIN authentication works. Others might not.

[Dovecot] mbox and maildir
by Shane Kerschtien 15 Oct '04

15 Oct '04

Is it possible to mix maildir and mbox formats with dovecot? For example, I would like ~/mail to be in maildir format yet keep the inbox (/var/mail/%u) in mbox format. If so, how may I go about this? Or am I stuck not being able to create subdirectories in ~/mail? Cheers, Shane

I dos not like qmail & Co, ldap... and cyrus is to big for me. I found tousand mosaiks in internet to build any email server... mostly bound to debian, suse, redhat what i not use and i prefer all piece self compile and package for Archlinux or Slackware. My problem is the choice of ingredients and later to assemble it. Community need howto's like above two and some working full complete recipe to self build. I hope to find a recipe for dovecot+postfix+tls+ssl+smtpauth and [postgresql|mysql|firebird|metakit|any.other.db] nora

[Dovecot] not enough information in the syslog

Although I set `auth_debug = yes' in the dovecot.conf, the line about my uid being too low was never logged by the server. Neither KMail nor Mozilla showed me the rejection message, that dovecot was giving them. I had to ktrace the process to see it and adjust first_valid_uid down. Yours, -mi

[Dovecot] painfully slow uploads
by Mikhail Teterin 14 Oct '04

14 Oct '04

I have several mail accounts, but collect all spam e-mail in the spam mailbox on one of them. After switching to dovecot (from imap-uw) I notice a very slow speed of bulk transfers and a very high CPU utilization by the dovecot's imap process during it -- sustained 62% of my server's Pentium2 @266MHz. Never saw such effects under imap-uw... My client is KMail (despite the awfull quality of its latest release). Hope, this helps. Yours, -mi

[Dovecot] assertion failed and debugging dovecot
by Doug Luce 14 Oct '04

14 Oct '04

I'm getting this error on a particular message in my Maildir: Oct 11 21:59:48 aurora dovecot: IMAP(doug): file ostream-file.c: line 646 (_send_istream): assertion failed: (instream->v_offset <= in_size) To me, more import than the question "why is this happening" is "how can I debug this?" Attaching gdb to the running imap process doesn't give me access to the proper function names to set up breakpoints and get a stack trace. Can someone with the experience give a quick how-to on debugging functions deep in dovecot? Thanks, Doug

[Dovecot] what exactly does outlook-idle workaround?
by Jonathan Salomon 13 Oct '04

13 Oct '04

Hi, Can anyone tell me what the 'client_workarounds = outlook-idle' directive exactly does? I have enabled it in my /etc/dovecot.conf, but the problem that I think it should solve still exsits. That is that after being IDLE for more than half an hour Dovecot will disconnect Outlook but Outlook never connects back. Therefore users receive new mail, but they don't get notified unless they press send/receive. So what does the workaround do? And how can I solve the problem? Thanks! Jonathan

[Dovecot] SASL
by alan premselaar 13 Oct '04

13 Oct '04

I've been browsing the wiki and thru my mail-list archives but haven't found an answer. does/can dovecot 0.99.x support authenticating with a SASL database? I'll be setting up a new mail server for my offices using Sendmail/MIMEDefang/ClamAV/etc with dovecot as the IMAP server. I'm not familiar at all with LDAP. I know that sendmail will authenticate to a SASL database and it's fairly easy to setup. My goal is that I can support "real" users (actual user accounts) but allow their mail passwords to be different than their login passwords, and changeable via some sort of CGI interface. (I also have 2 weeks to accomplish this) any assistance is appreciated alan

[Dovecot] Does dovecot support subfolders in Outlook (and in general)
by AWC Maillists 12 Oct '04

12 Oct '04

Ok, I am playing around with dovecot and things are running relatively smoothly. I am using Outlook as that is what the client uses for Email. I can copy messages to and from the IMAP folder. I can create folders from the root directory fine. My question is this. I have folders like this: IMAPServer --Inbox --Trash --WorkToDo Now when I try and create a subfolder in "WordToDo" I get an error message "Unable to create the folder. The server responded: 'Mailbox doesn't allow inferior mailboxes' When I try to create a subfolder in "Inbox" I get an error message "Unable to create the folder. The folder 'Inbox' cannot contains subfolders..." So is this a limitation of Dovecot? Another problem with Outlook? Or do I have some configuration problem on my end? Thanks. --- Charles PS: My first impressions of dovecot are very positive. It is a much cleaner and, so far, easier to handle IMAP server than the heavyweight UW & Cyrus IMAP servers. Congrats on a impressive program.

Thanks for answer, The config I have is very small (for now) All of my user have an account on the machine. Very soon I plan to switch to LDAP. For my needs, a PowerUser for all domains is enough.

Not yet. But I guess I should one day add support for it. Most SASL mechanisms support it directly without a kludgy username. I'm not sure about the configuration though. For passwd-file I guess there could be just one global flag which means that the user has access to everyone's mails. For LDAP and SQL I guess the pass_filter/password_query could have a few new %vars to describe the other user. Or maybe there needs to be a separate filter/query for that case. Hmm. Do you want the poweruser to have access to all mailboxes, or just for the one domain? What passdb are you using?

[Dovecot] Detecting unused accounts
by Ben Beuchler 12 Oct '04

I'm looking for a way to figure out which accounts have not been logged in to in over n days. It occurs to me that, perhaps, the way to do this would be to look at the mtime on one of the dovecot-maintained files, like 'dovecot-uidlist'. Is there a particular file that would be modified on (almost) every login, whether it be via POP or IMAP? -Ben -- Ben Beuchler There is no spoon. insyte(a)emt-p.org -- The Matrix

[Dovecot] Enable outlook-idle workaround.

I just recently discovered dovecot. I am evaluating the program and several clients uses Outlook/Outlook Express. In the clients issues section of dovecot.org is says "You should enable outlook-idle workaround" Ok, maybe I am missing something very obvious here but I can not find any documentation on how to implement the outlook-idle workaround. Can anyone point me to an article or something with more details on this issue? Thanks in advance.
