[Dovecot] Force "lower case" Folder Creation?
by Rich, Whidbey Telecom 28 Feb '07

28 Feb '07

We're exploring the use of "plus addressing" in our MTA (Exim), which delivers "user+topic(a)domain.com" to a user's "topic" folder. However, the case-sensitive nature of our ext3 filesystem means that a message destined to "topic" won't deliver to a user's "Topic" folder. For example, if a user creates a "Topic" folder, and gives "user+Topic(a)domain.com" to a web form that lower-cases it, delivery is deferred. Although we're checking to see if Exim can workaround this, is there a way Dovecot (1.0rc24) can force lowercase folder names without a patch? We'd hate to do this but are exploring our options. Thanks! Rich

[Dovecot] 1.0rc_15 - imap-login disappearing
by James Pattinson 28 Feb '07

28 Feb '07

Hi All I am trying to troubleshoot a problem that's been bugging me for several months. About once or twice per week my IMAP server seems to get in a state where no connections are possible (Thunderbird hangs at "Connected to <server>"). Restarting dovecot completely fixes the problem, until it occurs again, hours or days later. I caught the problem today after I rebooted my server, and monitored the running processes while attempting to connect. After each connection attempt, the number of imap-idle processes running decremented until none at all were running. Before the final imap-login process died, I attached an instance of strace to it - results here: http://www.pasteserver.net/286 I am running Dovecot 1.0_rc15 on a Gentoo server. It's a vmware virtual server - mentioning this now just in case, but I'm confident that's not anything to do with it, no other services are having any problems that I am aware of. I am using TLS and Maildir. I don't know enough about how dovecot is supposed to work, so I would appreciate some help in diagnosing this problem! Cheers, James

[Dovecot] Move deleted to trash
by Brian Taber 28 Feb '07

28 Feb '07

Is there a way to have messages marked to be deleted move to the trash folder automatically? I have moved from courier-imap (which dovecot performs muck better) but the one feature I really need is move to trash. Is there any plugins available for this?

[Dovecot] mail-log: Same log entry when one deletes/undeletes an e-mail.
by Tan Shao Yi 28 Feb '07

Hi Timo, I'm on RC24 with the mail-log plugin. It seems that when one deletes or undeletes a message, the log entries are the same: Deletion: dovecot: Feb 23 09:15:18 Info: IMAP(tansy): deleted: uid=4613, msgid=<E327C631261CD311BBAE00E081103C0901600871(a)ritchie.dev.virpack.com> Undelete: dovecot: Feb 23 09:15:24 Info: IMAP(tansy): deleted: uid=4613, msgid=<E327C631261CD311BBAE00E081103C0901600871(a)ritchie.dev.virpack.com> Is it a bug? :) Cheers.

[Dovecot] permissions problem reading INBOX

Hello, I'm sorry if I'm asking something that is documented - I could swear I saw something about this (dovecot changing to the uid of the entry in the userdb when accessing the mailbox), but now I cannot find it anywhere in the wiki! Dovecot seems to be getting the right uid for the mailbox, but then it is having permissions problems. The error is: Feb 27 17:31:08 rm-002-02 dovecot: auth(default): client in: AUTH 1 PLAIN service=POP3 lip=65.23.159.123 rip=65.23.128.14 resp= <hidden> Feb 27 17:31:08 rm-002-02 dovecot: auth(default): client out: OK 1 user=kclair Feb 27 17:31:08 rm-002-02 dovecot: auth(default): master in: REQUEST 1 17052 1 Feb 27 17:31:08 rm-002-02 dovecot: auth(default): master out: USER 1 kclair system_user=kclair uid=12346 gid=12346 home=/home/kclair Feb 27 17:31:08 rm-002-02 dovecot: POP3(kclair): open(/var/spool/mail/kclair, O_CREAT) failed: Permission denied Feb 27 17:31:08 rm-002-02 dovecot: POP3(kclair): stat() failed with mbox file /var/spool/mail/kclair: Permission denied The mbox file permissions are: -rw-rw---- 1 kclair mail 489 Feb 27 16:40 /var/spool/mail/kclair The /etc/passwd file entry is: kclair:x:12346:12346::/home/kclair:/bin/bash I am trying to use the following passdb combination: passdb: driver: pam args: dovecot deny: no pass: no master: no passdb: driver: passwd-file args: /usr/local/etc/passwd.dovecot deny: no pass: no master: no and userdb combination: userdb: driver: passwd args: userdb: driver: passwd-file args: /usr/local/etc/passwd.dovecot Am I missing something obvious?

Thanks for that. A more specific question: is there a way to have imap/pop-login processes log the PID of the child imap/pop process?

[Dovecot] relay-ctrl works
by Amitai Schlair 28 Feb '07

In case anyone still cares, relay-ctrl works with Dovecot. Dovecot's end of the bargain requires a dirty little script to set TCPREMOTEIP based on the arguments passed from imap-login: #!/bin/sh TCPREMOTEIP=`echo "$@" | sed -e 's|.* ||' -e 's|]$||'` export TCPREMOTEIP exec "$@" And this (long) line in dovecot.conf: mail_executable: envdir /etc/relay-ctrl /usr/local/bin/relay-ctrl- chdir /usr/local/bin/dovecot-settcpremoteip /usr/local/bin/relay-ctrl- allow /usr/local/libexec/dovecot/imap For the SMTP end of the bargain, relay-ctrl has docs for qmail-smtpd and mailfront.

28 Feb '07

Hello, I migrate from cucipop to dovecot. Thus I move users' mailboxes (mbox format) to another location. Some POP3 client (for example Outlook or TheBat!) use flag 'Do not delete messages from server'. After the user's mailbox have been moved to a new location all old messages is retrieved again and user get duplicates. Is there a way to avoid such issue?

[Dovecot] dovecot-auth (1.0rc24) on Solaris seems broken.
by Stephen Usher 28 Feb '07

28 Feb '07

I've trying to get dovecot-auth to talk to exim and have been running debugging on both sides. I've added the line: i_info("auth_client_input: client disconnected: %s", strerror(errno)); just after the "case -1" in the first switch statement in: auth-client-connection.c: auth_client_input() and get this in the logs: dovecot: Feb 27 13:35:09 Info: auth(default): auth_client_input: client disconnected: Illegal seek Now, on the exim end if I don't have the i_info() call in the routine the call to fgets() which exim is using never returns. If I put the i_info() call in there it does and gives an error, e.g. 2007-02-27 13:35:09 dovecot_plain authenticator failed for vanguard.earth.ox.ac.uk [163.1.22.82]: 435 Unable to authenticate at present: authentication socket protocol error Now, the istreams code in dovecot seems rather too obscure for me to debug any further. According to the read(2) man page under Solaris 10, the only version of read which can possibly return ESPIPE is pread(). Any ideas what's going on?

[Dovecot] Capability dropping support patch
by David 28 Feb '07

28 Feb '07

Hi, A week ago I submitted an early patch, please ignore it. The patch attached to this email has been tested and seems to work for me. I have also attached instead of inline to solve problems with spaces/tabs. The patch will, on systems that have libcap support, drop capabilities that Dovecot doesn't need. For example there is no need for CAP_SYS_MODULE, which enables module loading or CAP_SYS_PTRACE/CAP_SYS_ADMIN/etc. If libcap isn't installed then nothing will change, this is a compile-time only enhancement that isn't configurable. Personally I did not find that CAP_SYS_CHROOT was needed in order for me to authenticate and access my mailbox, but I haven't configured anything special with chrooting (yet). I added it because I see chroot() is used in src/lib/restrict-access.c. The patch was generated against 1.0-rc24 and tested with clients imp and Thunderbird. My configuration uses a virtual passdb, requires TLS for AUTH and exports auth-master under a different account. All of this appears to work correctly. I'd appreciate any comments, perhaps this will help safeguard the 1000EUR on non-hardened systems :) David

[Dovecot] Dovecot rc23 and rc24 freeze after authentication
by Garret Huntress 27 Feb '07

27 Feb '07

I had our production systems running on rc23, however we ran into problems when the server was under heavy load. Eventually, the server would begin to freeze all imap connection after authentication (according to the logs). A user would connect, authentication would succeed, and then the connection would sit until timing out. No error logs were produced. Upgrading to rc24 did not resolve the issue, but reverting to rc22 has. -Garret -- Garret W.

Re: [Dovecot] Solaris problem & exim. Please ignore it.
by Stephen Usher 27 Feb '07

27 Feb '07

Please ignore my previous question.. as it turns out it's a bug/feature of fprintf(3C) and sockets under Solaris. Exim was using fprintf to output the AUTH string and for some unknown reason it was hanging, possibly because the input buffer on the file stream wasn't empty or something. After modifying the Exim's dovecot authentication plug-in to use write(2) instead of fprintf(3C) it miraculously worked!

[Dovecot] lstats on all files in Maildir when opening an e-mail.
by Tan Shao Yi 27 Feb '07

27 Feb '07

Hi, I'm running RC19 on a Solaris 10 SPARC box. It seems that whenever I open an e-mail in any folder via IMAP, dovecot appears to scan every other folder in the Maildir. A truss reveals that it is lstat-ing every e-mail in every directory. I'm sorry I am sending only a fragment of the truss, it's really too long... but is this behaviour expected? Cheers, Tan Shao Yi lstat64("/var/qmail/maildirs/AA/AA/test@pacific.net.sg/Maildir/.qmail/new/1170337156.M209211P18431V025055F0I0000DAF0_0.recess1,S=2596", 0xFFBFF040) = 0 lstat64("/var/qmail/maildirs/AA/AA/test@pacific.net.sg/Maildir/.qmail/new/1170337594.M159985P18549V025055F0I0001891B_0.recess1,S=4111", 0xFFBFF040) = 0 lstat64("/var/qmail/maildirs/AA/AA/test@pacific.net.sg/Maildir/.qmail/new/1170338379.M564254P18933V025055F0I000196A3_0.recess1,S=3630", 0xFFBFF040) = 0 lstat64("/var/qmail/maildirs/AA/AA/test@pacific.net.sg/Maildir/.qmail/new/1170344035.M859029P24106V025055F0I000198E4_0.recess1,S=4254", 0xFFBFF040) = 0 lstat64("/var/qmail/maildirs/AA/AA/test@pacific.net.sg/Maildir/.qmail/new/1170344816.M69242P24829V025055F0I000199CB_0.recess1,S=3810", 0xFFBFF040) = 0 lstat64("/var/qmail/maildirs/AA/AA/test@pacific.net.sg/Maildir/.qmail/new/1170347789.M408186P27905V025055F0I00019A8F_0.recess1,S=3922", 0xFFBFF040) = 0 lstat64("/var/qmail/maildirs/AA/AA/test@pacific.net.sg/Maildir/.qmail/new/1170378895.M589722P25748V025055F0I00019279_0.recess1,S=2782", 0xFFBFF040) = 0 lstat64("/var/qmail/maildirs/AA/AA/test@pacific.net.sg/Maildir/.qmail/new/1170380726.M524353P29456V025055F0I0001AEE1_0.recess1,S=3619", 0xFFBFF040) = 0 lstat64("/var/qmail/maildirs/AA/AA/test@pacific.net.sg/Maildir/.qmail/new/1170381420.M702545P517V025055F0I0001B208_0.recess1,S=3028", 0xFFBFF040) = 0 getdents64(8, 0xFEE72000, 8192) = 0 close(8) = 0 lstat64("/var/qmail/maildirs/AA/AA/test(a)pacific.net.sg/Maildir/.qmail/maildirfolder", 0xFFBFF148) = 0 lstat64("/var/qmail/maildirs/AA/AA/test(a)pacific.net.sg/Maildir/.qmail/cur", 0xFFBFF148) = 0 openat(-3041965, "/var/qmail/maildirs/AA/AA/test(a)pacific.net.sg/Maildir/.qmail/cur", O_RDONLY|O_NDELAY|O_LARGEFILE) = 8 fcntl(8, F_SETFD, 0x00000001) = 0 fstat64(8, 0xFFBFEEE8) = 0 getdents64(8, 0xFEE72000, 8192) = 1088 lstat64("/var/qmail/maildirs/AA/AA/test@pacific.net.sg/Maildir/.qmail/cur/1169092926.M656431P6118V04010002I000023E9_0.recess1,S=4701:2,S", 0xFFBFF040) = 0 lstat64("/var/qmail/maildirs/AA/AA/test@pacific.net.sg/Maildir/.qmail/cur/1168983168.M76366P8906V04010002I000027AB_0.recess1,S=2345:2,S", 0xFFBFF040) = 0

[Dovecot] Bigcrypt password patch
by Philipp Kolmann 26 Feb '07

26 Feb '07

Hi, we are currently in the progress of switching an HPUX mailserver to linux and dovecot. The only issue so far is, that HPUX has bigcrypt for passwords > 8 chars. Bigcrypt uses standard libc crypt for every block of 8 chars. The linux pam modules have a bigcrypt.c file which can be used for dovecot as well to authenticate crypt and bigcrypt passwords. I have used the pam bigcrypt.c code to patch the mycrypt.c dovecot file. Maybe you could add this path (against branch_1_0 cvs). thanks Philipp Kolmann -- If you have problems in Windows: REBOOT If you have problems in Linux: BE ROOT
