[Dovecot] Maildir bugs
by Timo Sirainen 05 May '09

05 May '09

I just found out that when using deliver or saving mails with IMAP APPEND command there was all kinds of race condition bugs that could cause e.g.: dovecot-uidlist: Duplicate file entry at line 18: 1241457213.M690227P32531.host,W=3359:2,T (uid 170019 -> 170020) And who knows what else. If you've run into those problems, these patches should help: http://hg.dovecot.org/dovecot-1.1/rev/6bbe27c32cb8 http://hg.dovecot.org/dovecot-1.1/rev/003bebac2c76 http://hg.dovecot.org/dovecot-1.1/rev/96c8632775df They are pretty large though, hopefully won't break anything. But at least my stress tests can no longer break it. I'll probably release v1.1.15 RC in a few days so at least some people can try to break it before the final v1.1.15 :)

[Dovecot] questions about compiling Sieve plugin
by MercuryShadow 04 May '09

04 May '09

I'm using the info on the wiki to try to compile the sieve plugin for dovecot on a server running Debian Etch, but I'm getting nowhere because I'm stuck trying to find the directory to use in the "--with-dovecot=" argument when running the configure script. The wiki says: Compilation is identical among the CMUSieve and the new Sieve plugin. Use --with-dovecot=<path> to point to dovecot-config file's directory. There are two possibilities where this could exist: 1. If you configured Dovecot with --enable-header-install, you'll have dovecot-config installed in $prefix/lib/dovecot/ directory. 2. Compiled Dovecot sources' root directory. The problem is that there is no such file called "dovecot-config" on the server, and dovecot was installed from the Debian repositories, not compiled. There is no /usr/lib/dovecot or /usr/local/lib/dovecot. I figured that, as is the case with many Debian packages, the libraries needed to compile would be included in a "dovecot-dev" package, but I checked and there is no such package in the Debian repos. Does anyone know what I need to do in order to get this plugin compiled? -- View this message in context: http://www.nabble.com/questions-about-compiling-Sieve-plugin-tp23285989p232… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Problem with BODYSTRUCTURE (wrong charset)
by Craig Craig 04 May '09

04 May '09

Hi, I've changed a program that fetches mail via IMAP from an Exchange Server to use our Dovecot machine. But now I'm experiencing strange problems with seem to be caused by a wrong BODYSTRUCTURE answer that causes wrong charset handling. When fetchting the BODYSTRUCTURE I see this: Dovecot: 88 UID fetch 32 (BODYSTRUCTURE) * 1 FETCH (UID 32 BODYSTRUCTURE ("text" "plain" ("charset" "us-ascii") NIL NIL "7bit" 725664 9385 NIL NIL NIL NIL)) 88 OK Fetch completed. Exchange: 90 UID fetch 10 (BODYSTRUCTURE) * 2 FETCH (BODYSTRUCTURE (("TEXT" "PLAIN" ("charset" "iso-8859-1") NIL NIL "QUOTED-PRINTABLE" 2784 47 NIL NIL NIL)("IMAGE" "JPEG" ("name" "197254.jpg") NIL NIL "BASE64" 498806 NIL ("attachment" ("filename" "197254.jpg")) NIL)("IMAGE" "JPEG" ("name" "197254_1.jpg") NIL NIL "BASE64" 188424 NIL ("attachment" ("filename" "197254_1.jpg")) NIL)("IMAGE" "JPEG" ("name" "197254_2.jpg") NIL NIL "BASE64" 31878 NIL ("attachment" ("filename" "197254_2.jpg")) NIL)("TEXT" "PLAIN" ("name" "pix.xml") NIL NIL "QUOTED-PRINTABLE" 2934 49 NIL ("attachment" ("filename" "pix.xml")) NIL)("TEXT" "PLAIN" ("CHARSET" "US-ASCII") NIL NIL "7BIT" 0 1 NIL ("attachment" NIL) NIL) "mixed" ("Message-ID:" "<d2788bc14788ff16e67e63941937c1e1(a)foo.de>" "boundary" "000XMAIL000") NIL NIL) UID 10) 90 OK FETCH completed.

Any hint would be appreciated... Thanks in advance, Craig

Re: [Dovecot] fts-solr plugin issue (Marked invalid)

OK. Concentrating problem in one question. How to ignore "bad" message and index next one in indexing procedure (fts plugin) ?. Now, one "error 500" from solr and dovecot (# 1.1.11: /etc/dovecot/dovecot.conf # OS: Linux 2.6.21.7-2.fc8xen i686 Ubuntu 8.04.2 ext3 ) stop and each next search query repeat the story. I've explored fts, and ftp-solr directories in src, without success for now. Timo, you understand code much bettter, can you help me and point to place in code, or probably create some patch, if possible ?.

[Dovecot] login_max_processes_count and logs
by Dominique Fournier 04 May '09

04 May '09

Hello, Our server reach today the login_max_processes_count. Dovecot works well and don't accept any new connection. But it doesn't log anything about this problem : we are blind why the connection is refused for the clients. Could you add a log when the connection limit is reached or (maybe better) a log with the occupation for the beginning of each connection ? Thanks Dom Dovecot version 1.0.15 on Debian AMD64

[Dovecot] Strange virtual users issues
by Ovi C 02 May '09

02 May '09

Hi i'm using dovecot with virtual users from a postgresql database backend on a Debian Lenny system. I'm using qmail as MTA. Mostly everything seems to work ok , except the fact that the mail delivered never reaches virtual user's INBOX. Here's the dovecot config: dovecot -n # 1.0.15: /etc/dovecot/dovecot.conf base_dir: /var/run/dovecot/ log_path: /var/log/dovecot.log log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap ssl_disable: yes login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_greeting: Server ready to process requests. login_process_per_connection: no max_mail_processes: 512 verbose_proctitle: yes first_valid_gid: 61 last_valid_gid: 2003 mail_privileged_group: mail mail_location: maildir:~/Maildir mail_debug: yes mail_plugins: quota autocreate imap_client_workarounds: outlook-idle delay-newmail auth default: mechanisms: plain login digest-md5 passdb: driver: pam passdb: driver: passwd passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: passwd userdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: prefetch socket: type: listen client: path: /var/run/dovecot/auth-client mode: 432 master: path: /var/run/dovecot/auth-master mode: 384 user: root group: mail plugin: quota: maildir acl: vfile:/etc/dovecot-acls trash: /etc/dovecot-trash.conf lazy_expunge: .EXPUNGED/ .DELETED/ .DELETED/.EXPUNGED/ autocreate: Trash autocreate2: Spam The setup is as follows: I've created a system user named vmail in /home with a group also called vmail. The virtual users are created in /home/vmail/username when i configure an account from thunderbird. If I send an message from a virtual user to an system user everythings is ok. The system user get's the mail in his Maildir. But if I send a message from the system user to the virtual user the MTA's log says that the message has been delivered but it never reaches virtual user's INBOX. Here's a snip from logs both qmail's and dovecot's: cat /var/log/qmail.log status: local 0/10 remote 0/20 new msg 155041 info msg 155041: bytes 263 from <caretaker@localhost.> qp 4560 uid 1000 starting delivery 1: msg 155041 to remote akkersson@localhost. status: local 0/10 remote 1/20 new msg 155147 info msg 155147: bytes 438 from <caretaker@localhost.> qp 4563 uid 64011 starting delivery 2: msg 155147 to local akkersson@localhost status: local 1/10 remote 1/20 delivery 1: success: 127.0.0.1_accepted_message./Remote_host_said:_250_ok_1241272738_qp_4563/ status: local 1/10 remote 0/20 end msg 155041 delivery 2: deferral: status: local 0/10 remote 0/20 cat /var/log/dovecot.log dovecot: 2009-05-02 16:30:46 Info: Dovecot v1.0.15 starting up dovecot: 2009-05-02 16:30:46 Info: auth(default): pgsql: Connected to maildb dovecot: 2009-05-02 16:32:00 Info: IMAP(akkersson): Loading modules from directory: /usr/lib/dovecot/modules/imap dovecot: 2009-05-02 16:32:00 Info: IMAP(akkersson): Module loaded: /usr/lib/dovecot/modules/imap/lib10_quota_plugin.so dovecot: 2009-05-02 16:32:00 Info: IMAP(akkersson): Module loaded: /usr/lib/dovecot/modules/imap/lib11_autocreate_plugin.so dovecot: 2009-05-02 16:32:00 Info: IMAP(akkersson): Effective uid=2003, gid=61, home=/home/vmail/akkersson dovecot: 2009-05-02 16:32:00 Info: IMAP(akkersson): maildir: data=/home/vmail/akkersson/Maildir dovecot: 2009-05-02 16:32:00 Info: IMAP(akkersson): maildir: root=/home/vmail/akkersson/Maildir, index=/home/vmail/akkersson/Maildir, control=, inbox= dovecot: 2009-05-02 16:32:00 Info: imap-login: Login: user=<akkersson>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured dovecot: 2009-05-02 16:58:11 Info: IMAP(akkersson): Disconnected: Logged out but akkersson's INBOX is empty..

Great. Thank you so much for responding. It hangs at Tying 127.0.0.1 The funny part is that one day it works fine and the next day it just hangs. And its not that the service is completely unresponsive. If 200 users try to connect, 10 get through and are able to download. However which 10 get through depends on luck! Its been going on for the past one week and really driving me crazy. I have changed everthing including the server, but the problem persists. How do I get a clue where the problem is?

Which part of it exactly is slow? For example in a typical pop3 connection you have: Trying 127.0.0.1... Connected to localhost.
