[Dovecot] Corrupted index cache
by Joseph W. Breu 12 Jul '06

12 Jul '06

Upgraded from rc1 to rc2 and I am still getting the Corrupted index cache file warnings in syslog Jul 12 10:10:19 pop1.cfu.net dovecot: IMAP(breu(a)cfu.net): Corrupted index cache file /var/spool/mail/filer/storage//cfu.net/b/r/breu/dovecot.index.cache: invalid record size Is this something to be worried about? Is the cache just rebuilt upon notification of corruption? Thanks, --------------------------------------------------------- Joseph W.

[Dovecot] passwd authentication issues (ATTN: Petar)
by Bruce Lane 12 Jul '06

12 Jul '06

Hi, Petar, For whatever reason, I didn't see your most recent reply until I checked the web archives. To answer your questions... Is my dovecot running chrooted? Not that I know of. However, the option to (apparently) decide this is confusing at best. Here is what I have entered. # chroot login process to the login_dir. Only reason not to do this is if you # wish to run the whole Dovecot without roots. # http://wiki.dovecot.org/Rootless login_chroot = yes Now, my guts tell me that this WILL make it run chrooted. However, reading the material at this link... http://wiki.dovecot.org/Rootless ...says otherwise, and that setting this to 'no' would be making it run chrooted. For reference, this is the process line from ps -aux|grep dovecot root 3182 0.0 1.4 256 876 ? Ss Sun08PM 10:10.06 /usr/local/sbin/dovecot Also, something else just turned up in the process list that I'm not sure I understand. Specifically... root 1817 0.0 1.6 324 1056 ? S 8:53PM 0:00.19 dovecot-auth dovecot 2191 0.0 3.0 256 1940 ? S 8:53PM 0:00.97 imap-login root 3182 0.0 1.4 256 876 ? Ss Sun08PM 10:11.78 /usr/local/sbin/dovecot dovecot 6333 0.0 3.0 256 1940 ? S 8:53PM 0:00.93 imap-login dovecot 8133 0.0 3.0 256 1940 ? S 8:53PM 0:00.97 imap-login dovecot 8397 0.0 3.0 256 1940 ? S 8:53PM 0:00.96 imap-login dovecot 16144 0.0 3.0 256 1940 ? S 8:53PM 0:00.92 imap-login This has me deeply confused. I'm not running IMAP, I'm not interested in running IMAP, I don't want anything to do with IMAP. However, there's five processes for imap-login. What gives? On to your second question: Are /etc/pwd.db and /etc/spwd.db available? Yes, both are listed in the directory of /etc as follows. -rw-r--r-- 1 root wheel 40960 Jul 9 09:56 /etc/pwd.db -rw------- 1 root wheel 40960 Jul 9 09:56 /etc/spwd.db featherweb: {41} How "available" this makes them (I don't know what context you were asking in), I'm not sure. Just for giggles, I tried chaning the permissions on spwd.db so that it was world-readable. Doing so had no effect. I still get password failure errors when I try to authenticate a pop3s connection from the client program. One other question: Pegasus (the mail client) has two options for secure POP connections besides apop (which I've shelved for the moment): STLS and direct SSL connection. I've got it set to direct SSL at the moment. Does this sound right? Looking forward to the next set of replies. Thanks much. -=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner & Head Hardware Heavy, Blue Feather Technologies -- http://www.bluefeathertech.com kyrrin (at) bluefeathertech do/t c=o=m "If Salvador Dali had owned a computer, would it have been equipped with surreal ports?"

[Dovecot] Problems with deliver (LDA)
by Claus Alboege 12 Jul '06

12 Jul '06

Hi, I'm using Dovecot's (1.0.rc2) 'deliver' (no sieve) as LDA - calling it from a .qmail file. It seems that 'deliver' destroys "message/rfc822" attachments (forward as attachment). My .qmail file looks like this, and use qmail to deliver a copy directly to my Maildir, and 'deliver' to deliver a second copy of the same message to the same Maildir: % cat .qmail ./Maildir/ |preline /usr/libexec/dovecot/deliver After forwarding a message (as attachment) to my account, I get the following 2 files in my Maildir. Check the difference in size: % ls -l Maildir/new -rw------- 1 csa csa 2818 2006-07-06 09:29 1152170973.7420.silver -rw------- 1 csa csa 1372 2006-07-06 09:29 1152170973.P7422Q0M136220.silver Grepping for ^Content-* in the 2 mails show that a part is missing. % cd Maildir/new % grep ^Content * 1152170973.7420.silver:23:Content-Type: multipart/mixed; 1152170973.7420.silver:28:Content-Type: text/plain; charset = "iso-8859-1" 1152170973.7420.silver:29:Content-Transfer-Encoding: quoted-printable 1152170973.7420.silver:34:Content-Type: message/rfc822; name="Testing" 1152170973.7420.silver:35:Content-Transfer-Encoding: 7bit 1152170973.7420.silver:36:Content-Disposition: attachment; filename="Testing" 1152170973.7420.silver:64:Content-Transfer-Encoding: quoted-printable 1152170973.7420.silver:65:Content-Type: text/plain; charset="iso-8859-1" 1152170973.P7422Q0M136220.silver:24:Content-Type: multipart/mixed; 1152170973.P7422Q0M136220.silver:29:Content-Type: text/plain; charset = "iso-8859-1" 1152170973.P7422Q0M136220.silver:30:Content-Transfer-Encoding: quoted-printable 1152170973.P7422Q0M136220.silver:35:Content-Type: message/rfc822; name="Testing" 1152170973.P7422Q0M136220.silver:36:Content-Transfer-Encoding: 7bit 1152170973.P7422Q0M136220.silver:37:Content-Disposition: attachment; filename="Testing" (sorry for the long lines) The offset in linenumbers is caused the the From line added by 'deliver'. So, am I missing something here (execpt from the attachment) - is there anything in 'deliver' that could cause this behaviour? Please let me know if you need further information or details.

[Dovecot] Shared folders not woking for me
by Nagy László 11 Jul '06

11 Jul '06

Hello, I'm new to dovecot, please forgive me my silly questions. :-) My OS is FreeBSD 6.1. I just installed dovecot 1.0.beta9. I have created a public namespace this way: namespace public { separator = / prefix = Public/ location = maildir:/var/mail/public } namespace private { separator = / prefix = location = maildir:/home/%u/Maildir inbox = yes } Then I created a new group and added a user to it: pw groupadd das pw usermod testuser -g das Then I created some files in /var/mail/public: drwxrwx--- 2 testuser das 512 Jul 11 19:22 Tasks drwx------ 2 testuser mail 512 Jul 11 19:20 cur drwxrwx--- 2 testuser das 512 Jul 11 19:24 dovecot-shared drwx------ 2 testuser mail 512 Jul 11 19:20 new drwx------ 2 testuser mail 512 Jul 11 19:20 tmp Then I restarted dovecot, and I tried to subscribe to 'Tasks', but my email client (Thunderbird 1.5) does not allow it. My other problem is about the "inbox = yes" setting. The private namespace does have an inbox, and it shows up in thunderbird. But it does not show my e-mails. I know that I have emails, I can read them with the 'mail' command. Please help me. Laszlo

Re: [Dovecot] Dovecot and MySQL auth - initial setup issues

If you setup is in a virtual mailbox setup then your query should look something like this: user_query = SELECT maildir, 500 AS uid, 500 AS gid FROM users WHERE id = '%u' Try that out, replacing the 500's with the appropriate uid and gid and let me know what you see then.

[Dovecot] Dovecot and MySQL auth - initial setup issues
by Andrew Hearn 11 Jul '06

11 Jul '06

Hello, I'm just setting up a new server and wanting to use MySQL for user authentication. Here is what I have: Fedora Core 5: 2.6.17-1.2145_FC5 Dovecot v1.0.rc2 (RPM install from atrpms.net) MySQL v5.0.22 SquirrelMail v 1.4.6-7.fc5 ...Running on a Dual XEON machine I've added the following to dovecot.conf: auth default { passdb sql { args = /etc/dovecot-mysql.conf } userdb sql { args = /etc/dovecot-mysql.conf } The rest of dovecot.conf is standard. /etc/dovecot-mysql.conf has: driver=mysql connect = host=127.0.0.1 port=3306 dbname=maildb user=root client_flags=0 password_query = SELECT password FROM users WHERE id = '%u' user_query = SELECT maildir FROM users WHERE id = '%u' (I've run the SQL queries within mysql and they give the right results) When I start Dovecot the log shows: dovecot: Jul 11 12:47:25 Info: Dovecot v1.0.rc2 starting up dovecot: Jul 11 12:47:27 Info: auth-worker(default): mysql: Connected to 127.0.0.1 (maildb) When I try to log in using SquirrelMail, it takes about 3 seconds, then I get dovecot: Jul 11 12:48:00 Info: imap-login: Aborted login: user=<andrew(a)mail-test.aaisp.net.uk>, method=PLAIN, rip=::ffff:127.0.0.1, lip=::ffff:127.0.0.1, secured ...So, no log of it trying MySQL... And SquirrelMail then says: Unknown user or password incorrect Any ideas of what I'm missing? Thanks! Andrew.

[Dovecot] Authentication error with corrections
by Bruce Lane 11 Jul '06

11 Jul '06

Hi, Curtis (and the group), I tried setting up Dovecot's auth default section as you described, with both authdb and userdb set to 'passwd.' It let the authenticated session start on the POP side, but I got consistent authentication failures on the client side that the passwords didn't match. I don't have any more time to mess with it this morning, but I will make it a point to try 'shadow' when I get in this evening. It's possible that NetBSD wants to work that way. Thanks for your help. -=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner & Head Hardware Heavy, Blue Feather Technologies -- http://www.bluefeathertech.com kyrrin (at) bluefeathertech do/t c=o=m "If Salvador Dali had owned a computer, would it have been equipped with surreal ports?"

[Dovecot] Assertion fails (mail_cache_add) in dovecot 1.0 RC 2
by Jens 11 Jul '06

11 Jul '06

The log looks like this: dovecot: Jul 11 10:38:39 Error: IMAP(ni): file mail-cache-transaction.c: line 703 (mail_cache_add): assertion failed: (file_field != (uint32_t)-1) dovecot: Jul 11 10:38:39 Error: child 31316 (imap) killed with signal 6 What I did: 1. Start dovecot with a fresh account so that no folders exist. 2. Start Thunderbird and create a folder "Mails gespeichert auf nasdrive" 3. Put a message into the folder (with Outlook) 4. Edit this message with Thunderbird and Save it. 5. Thunderbird creates the "Draft" folder but the message never gets there. 6. The log file contains the message above! 7. Check if missing folder is source of issue: Edit the message again with Thunderbird and Save it again. 8. The message appears properly in the Draft folder. Additional Info: # dovecot --version 1.0.rc2 # dovecot --build-options Build options: ioloop=poll notify=dnotify ipv6 openssl SQL drivers: Passdb: checkpassword passwd passwd-file shadow Userdb: checkpassword passwd prefetch passwd-file static Regards, Jens
