[Dovecot] stat failed: Not a directory
by Andrea 17 Feb '08

17 Feb '08

I have recently installed dovecot on a FreeBSD mailserver running postfix. But when I try to login with imap/pop3, I always get an error "stat failed: Not a directory". I guess it is something wrong with the mail format postfix uses to store the message, but I don't seem to find the correct solution. Here's the postfix log with the successful delivery: Feb 17 08:58:24 mailsrv2 postfix/smtpd[75706]: connect from pc17r2.domain.com[10.0.1.17] Feb 17 08:59:07 mailsrv2 postfix/smtpd[75706]: 290F1B81D: client= pc17r2.domain.com[10.0.1.17] Feb 17 08:59:20 mailsrv2 postfix/cleanup[75710]: 290F1B81D: message-id=<20080217075907.290F1B81D(a)mailsrv2.domain.com> Feb 17 08:59:20 mailsrv2 postfix/qmgr[75703]: 290F1B81D: from=<andrea(a)vp44.net>, size=384, nrcpt=1 (queue active) Feb 17 08:59:21 mailsrv2 postfix/virtual[75711]: 290F1B81D: to=<andrea(a)internal.domain.com>, relay=virtual, delay=39, delays=39/0.26/0/0.24, dsn=2.0.0, status=sent (delivered to mailbox) Feb 17 08:59:21 mailsrv2 postfix/qmgr[75703]: 290F1B81D: removed And here dovecot: Feb 17 09:00:24 mailsrv2 dovecot: imap-login: Login: user=<andrea(a)internal.domain.com>, method=PLAIN, rip=10.0.1.2, lip=10.0.1.17 Feb 17 09:00:24 mailsrv2 dovecot: IMAP(andrea(a)internal.domain.com): stat(/usr/local/virtual/internal.domain.com/andrea/cur) failed: Not a directory Feb 17 09:00:24 mailsrv2 dovecot: IMAP(andrea(a)internal.domain.com): stat(/usr/local/virtual/internal.domain.com/andrea/cur) failed: Not a directory Feb 17 09:00:24 mailsrv2 dovecot: IMAP(andrea(a)internal.domain.com): Connection closed Dovecot -n: #

[Dovecot] --without-linux-quota
by Heiko Schlichting 17 Feb '08

17 Feb '08

Hi, compiling dovecot 1.1.beta16 with configure option "--without-linux-quota" failed in line 444 of quota-fs.c as _LINUX_QUOTA_VERSION is an unquoted "no". Additionally using "--without-linux-quota" does not remove the quota code from dovecot as I expected. This is not a problem to me but it would be more clear if configure failed if "--without-linux-quota" is used and it is not possible to strip the quota code from dovecot. I know that I can use "--with-linux-quota=..." to specify a quota version but for me this option implied that it is possible to remove the filesystem quota code entirely if it is not needed.

[Dovecot] Dovecot pgsqlauthentication database reconnection/failover problem
by Frank Wang 17 Feb '08

17 Feb '08

Hi, Our mail system uses dovecot-1.0-1.2.rc15.el5 in Centos-5.1 as our imap server. It connects to a pgsql database in another server as authentication backend. It works fine except occasionally fails to reconnect to the database after temporary network block, and dovecot has to be restarted to work again in such case. Since I can't find any specific setting in dovecot.conf to handle this reconnection problem, I opt to build a failover pgsql backend. Google led me to http://www.dovecot.org/list/dovecot/2008-January/027899.html. I followed the thread to modify my dovecot-sql.conf containing "connect = host=pgsql1 host=pgsql2 dbname=xxxx user=xxxx" If both databases are available, dovecot will choose pgsql2 as the default one, and user login works flawlessly. But when I block all traffic to host pgsql2, dovecot will repeatedly try pgsql2 and neglect available host pgsql1. I don't find relevent information in the dovecot wiki either. Can anyone here shed a light on me? Thanks in advance! Regards, Frank Wang

[Dovecot] v1.1.beta16 released
by Timo Sirainen 16 Feb '08

16 Feb '08

http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta16.tar.gz http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta16.tar.gz.sig If all goes well, I'll release v1.1.rc1 in a couple of days. Now's a good time to start testing v1.1 :) Changes since beta15: - Squat is finally working and supports expunging messages from it. I've been stress testing it and can't find any problems anymore. - Some index/cache crashfixes TODO for v1.1.0: - mbox: We write From_-lines to message bodies unescaped and assume Content-Length: header allows us to skip over them. This probably worked in v0.99, but got broken when mbox code was rewritten for v1.0. This should be fixed somehow. - dbox: fsync()ing isn't done for saved messages. - maildir: after rename()ing files from tmp/ to new/ we should probably fsync() the new/ directory. - Squat: NFS support. Check/fix a potential locking problem. - Lucene: It gives all kinds of locking errors which cause other problems. Maybe Dovecot should do the locking itself so Lucene never needs to wait for locks? Has anyone here used Lucene before and knows about these issues?

[Dovecot] [patch] make <chroot>/./<home> a config option.
by Diego Liziero 16 Feb '08

16 Feb '08

Hi, I think that the wu-ftp style chroot /./ should be a configurable option. In our servers we have some home directories in /chroot-web/./username (where web users can upload their web sites in a chrooted environment) and all imap mail in /mail-disk/username. We are planning a dovecot migration from our modified version of uw-imap and we noticed that the chroot in /chroot-web/ can't be disabled. This patch adds the bool option home_slash_dot_slash_chroot (feel free to change this name to something easier to understand). Setting this to "no" disables the wu-ftp style /./ chroot. I hope this feature can be considered useful and soon included in dovecot. Regards, Diego Liziero.

Hey guys, Is it possible to deny a user on POP or IMAP! For example, on the primary server we use POP3 and IMAP but how I can force a user to use POP3 and be unable to authenticate on IMAP ? Thanks Sebastien

[Dovecot] dovecot rejecting auth after working a few times

Greetings all, I've got a dovecot server up that works just fine for a few minutes, and then suddenly won't authenticate users. On top of it, it keeps spawning dovecot-auth processes that won't go away. If any one has seen this or knows what's causing it I sure could use some help. Thanks much.

[Dovecot] Managesieve with local accounts
by Michael Baecker 15 Feb '08

15 Feb '08

Hello, I've got a problem using the plugin managsieve in dovecot (1.0.10 on gentoo linux). I use local unix accounts on a linux machine, one for each user with a .maildir in there home directory. Here is a snippet of the logging. Feb 14 20:17:48 obelix dovecot: Dovecot v1.0.10 starting up Feb 14 20:18:00 obelix dovecot: imap-login: Login: user=<michael>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Feb 14 20:18:00 obelix dovecot: imap-login: Login: user=<michael>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Feb 14 20:18:00 obelix dovecot: IMAP(michael): Disconnected: Logged out Feb 14 20:18:00 obelix dovecot: IMAP(michael): Disconnected: Logged out Feb 14 20:18:00 obelix dovecot: imap-login: Login: user=<michael>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Feb 14 20:18:00 obelix dovecot: IMAP(michael): Disconnected: Logged out Feb 14 20:18:00 obelix dovecot: imap-login: Login: user=<michael>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Feb 14 20:18:00 obelix dovecot: IMAP(michael): Disconnected: Logged out Feb 14 20:19:04 obelix dovecot: managesieve-login: Disconnected: user=<michael>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, TLS I don't get the sieve script and can't also save a script. It looks quite ugly "login: Disconnected" in the last line. Here is my config file (without the comments): protocols = imap managesieve listen = * disable_plaintext_auth = yes ssl_disable = no ssl_cert_file = /etc/ssl/dovecot/server.pem ssl_key_file = /etc/ssl/dovecot/server.key mail_location = maildir:~/.maildir mail_debug = no verbose_proctitle = yes first_valid_uid = 10 protocol imap { } protocol pop3 { } protocol managesieve { sieve=~/.dovecot.sieve sieve_storage=~/sieve listen = *:2000 } protocol lda { postmaster_address = postmaster(a)baecker.com mail_plugins = cmusieve } auth default { mechanisms = plain passdb pam { args = "*" } userdb passwd { args = blocking=yes } user = root socket listen { client { path = /var/spool/postfix/auth/dovecot mode = 0666 user = postfix group = postfix } master { path = /var/spool/postfix/auth/auth-master mode = 0666 user = postfix group = postfix } } } dict { } plugin { } The client worked already with pysieved over xinetd (Horde Ingo and squirrelmail with avelsieve worked). But this isn't realy a solution. Can anybody help me? Do you need anything, I didn't wrote her? Thanks in advance Michael Baecker
