Hi, I found the following in my logfiles: The failure is not reproducable at the moment. System is delivering mails to mailboxes with no problems at all. It is a production installation with medium load. dovecot --version: 1.1.7 OS: Linux (Gentoo/x86 stable) - grsec enabled kernel deliver.log: deliver(user(a)example.tld): Panic: file istream-tee.c: line 144 (i_stream_tee_read): assertion failed: (ret > 0) deliver(user(a)example.tld): Error: Raw backtrace: /usr/libexec/dovecot/deliver [0x80c8032] -> /usr/libexec/dovecot/deliver(default_fatal_handler+0x3a) [0x80c812a] -> /usr/libexec/dovecot/deliver [0x80c796c] -> /usr/libexec/dovecot/deliver [0x80cf5f8] -> /usr/libexec/dovecot/deliver(i_stream_read+0x2d) [0x80cc5dd] -> /usr/libexec/dovecot/deliver(i_stream_read_data+0x1d) [0x80cc6ed] -> /usr/libexec/dovecot/deliver [0x80d52cb] -> /usr/libexec/dovecot/deliver(o_stream_send_istream+0x35) [0x80d45b5] -> /usr/libexec/dovecot/deliver(maildir_save_continue+0x32) [0x806fbb2] -> /usr/libexec/dovecot/deliver(mail_storage_copy+0xd2) [0x8096512] -> /usr/libexec/dovecot/deliver(maildir_copy+0x5b) [0x806c51b] -> /usr/libexec/dovecot/deliver(deliver_save+0x17d) [0x805cbfd] -> /usr/libexec/dovecot/deliver(main+0x161b) [0x805e41b] -> /lib/libc.so.6(__libc_start_main+0xdc) [0x559a7fdc] -> /usr/libexec/dovecot/deliver [0x805bb41] mta.log (postfix with dovecot/deliver pipe transport): Jan 22 00:02:09 argon postfix/pipe[21251]: E8126A3671: to=<user(a)example.tld>, orig_to=<localalias>, relay=dovecot, delay=0.38, delays=0.03/0/0/0.35, dsn=5.3.0, status=bounced (Command died with signal 6: "/usr/libexec/dovecot/deliver") Neither the grsec.log nor dmesg said anything special.

Hi! I have a question about the dictionary quota :storage and :messages values in MySql quota table. How to interpret the following values? Why some values are negative?

[Dovecot] Shared mailboxes support status
by Thomas Hummel 26 Jan '09

26 Jan '09

Hello Timo, I'm running dovecot-1.1.8 and I'm about to play with namespaces and shared mailboxes. I've read on the list that the Kolab people did contribute to that, and I read at http://dovecot.org/doc/NEWS-1.2 "+ Full support for shared mailboxes and IMAP ACL extension." I'd like to know the differences between shared mailboxes support between 1.1. and 1.2 branches and if it may be considered "safe" to use shared mailboxes on a production server running 1.1.8+ dovecot version (i.e. is it working and how, compared to the upcoming 1.2 release). I guess part of the answer is in the diffences between shared and public namespaces handling.

[Dovecot] Postfix and Dovecot
by Leonardo Coelho 26 Jan '09

26 Jan '09

Hi Everybody, I'm mount two failover servers which use Postfix and Dovecot but the hostname of the machines r diferent: first node # uname -n # mail secound node #uname -n #mail2 So far so good, the real problem is that the e-mail file name on server is like this: 1232449377.P31789Q0M963611.mail2 and when I using the server called mail the file stay like this: 1232449377.P31789Q0M963611.mail I'm using drbd disk for the mailboxes and when I'm using the server called mail the files with mail2 on the end is not read for the dovecot when the user turn on the mail client but if I change the end from mail2 to mail that's ok the dovecot can read. How can I make dovecot read both files or any name on the end?

Re: [Dovecot] Dovecot upgrade broke per-user Sieve scripts

I tried adding it to global, and it didn't change anything, but then I just realized that I still had it in LDA, and so once I removed that part, and only have the configuration in global, it works! Thank you very much for your help Noel. :) Cheers -- John Reese LeetCode.net

[Dovecot] Dovecot upgrade broke per-user Sieve scripts
by John Reese 25 Jan '09

25 Jan '09

Hi all, I'm migrating my private mail server from Dovecot 1.0.10 to Dovecot 1.1.4 (both the latest package in Ubuntu Hardy and Intrepid, resp.). I'm using Postfix with Postfixadmin virtual users , passing mail to Dspam, which in turn passes email to the Dovecot LDA. The relevant configuration section is attached below. When running on the old version of Dovecot, the LDA correctly executed either the user's personal sieverc script, or the global sieverc, as expected. However, after the upgrade to 1.1.4, Dovecot will not execute any per-user Sieve scripts, although the configuration and file permissions hasn't changed. I've added debug logging to Dovecot, and the relevant portions of the log file are also attached below. What am I missing here? Why can't cmusieve find the user's script? Did the configuration for Sieve change? I've read and re-read the Dovecot wiki page for Sieve, and I can't see why my configuration should be causing any troubles. All help or suggestions are greatly appreciated. Thank you. ### dovecot.conf protocols = imap imaps disable_plaintext_auth = no mail_debug = yes log_path = /var/log/dovecot.log info_log_path = /var/log/dovecot.log mail_location = maildir:/srv/mail/%u/Maildir first_valid_uid = 900 ssl_cert_file = /srv/ssl/dovecot.pem ssl_key_file = /srv/ssl/leetcode.net.key auth default { mechanisms = plain login passdb sql { args = /srv/etc/dovecot/dovecot-mysql.conf } userdb sql { args = /srv/etc/dovecot/dovecot-mysql.conf } socket listen { master { path = /var/run/dovecot/auth-master mode = 0600 user = vmail } client { path = /var/spool/postfix/private/auth mode = 0600 user = postfix group = postfix } } } protocol lda { log_path = /srv/mail/dovecot-deliver.log auth_socket_path = /var/run/dovecot/auth-master postmaster_address = postmaster(a)leetcode.net mail_plugins = cmusieve sieve_global_path = /srv/mail/sieverc plugin { sieve = /srv/mail/%u/sieverc } } ### end dovecot.conf ### dovecot.log deliver(jreese(a)leetcode.net): Jan 24 14:30:40 Info: Loading modules from directory: /usr/lib/dovecot/modules/lda deliver(jreese(a)leetcode.net): Jan 24 14:30:40 Info: Module loaded: /usr/lib/dovecot/modules/lda/lib90_cmusieve_plugin.so deliver(jreese(a)leetcode.net): Jan 24 14:30:40 Info: auth input: jreese(a)leetcode.net deliver(jreese(a)leetcode.net): Jan 24 14:30:40 Info: auth input: maildir=jreese(a)leetcode.net/ deliver(jreese(a)leetcode.net): Jan 24 14:30:40 Info: auth input: uid=900 deliver(jreese(a)leetcode.net): Jan 24 14:30:40 Info: auth input: gid=900 deliver(jreese(a)leetcode.net): Jan 24 14:30:40 Info: maildir: data=/srv/mail/jreese(a)leetcode.net/Maildir deliver(jreese(a)leetcode.net): Jan 24 14:30:40 Info: maildir++: root=/srv/mail/jreese(a)leetcode.net/Maildir, index=, cont> deliver(jreese(a)leetcode.net): Jan 24 14:30:40 Info: cmusieve: /srv/mail/%u/sieverc doesn't exist deliver(jreese(a)leetcode.net): Jan 24 14:30:40 Info: cmusieve: Using sieve path: /srv/mail/sieverc deliver(jreese(a)leetcode.net): Jan 24 14:30:40 Info: cmusieve: Executing script /srv/mail/sievercc ### end dovecot.log -- John Reese LeetCode.net
