[Dovecot] child (login) killed with signal 9
by Matt LaPlante 19 Dec '07

19 Dec '07

Hi, I'm running dovecot on an Ubuntu server (1:1.0.5-1ubuntu2). Dovecot provides pop3, imap, and sasl to postfix. The setup works quite nicely, however I do have one error that shows up repeatedly in my dovecot.log. <snip> dovecot: 2007-12-12 09:29:06 Error: child 32765 (login) killed with signal 9 dovecot: 2007-12-12 09:29:06 Error: child 18039 (login) killed with signal 9 dovecot: 2007-12-12 10:05:07 Error: child 26088 (login) killed with signal 9 dovecot: 2007-12-12 10:05:07 Error: child 5271 (login) killed with signal 9 dovecot: 2007-12-12 10:05:07 Error: child 5273 (login) killed with signal 9 <snip> I'm not aware that this is actually causing problems, but since it shows up several hundred times a day on a couple-user setup, I'm rather curious about what's causing it. Thanks, Matt

[Dovecot] maildirsize quota counting locking account?

19 Dec '07

Hi, I've just straced a dovecot imap process and found one thread sitting there doing hundreds and hundreds of maildirsize updates as follows: > > open("/home/virtual/mydomain.com/home/admin/Maildir/maildirsize", O_RDWR|O_APPEND) = 7 > read(7, "10485760000S\n1562717408 107547\n-"..., 5120) = 2446 > read(7, "", 2674) = 0 > write(1, "* 1810 FETCH (UID 1815 RFC822.SI"..., 2031) = 2031 > setsockopt(1, SOL_TCP, TCP_CORK, [0], 4) = 0 > epoll_wait(4, {{EPOLLIN, {u32=101056896, u64=2370923004288}}}, 5, 2584) = 1 > read(0, "2838 UID fetch 1816 (UID RFC822."..., 2974) = 51 > setsockopt(1, SOL_TCP, TCP_CORK, [1], 4) = 0 > close(7) = 0 > open("/home/virtual/mydomain.com/home/admin/Maildir/maildirsize", O_RDWR|O_APPEND) = 7 > read(7, "10485760000S\n1562717408 107547\n-"..., 5120) = 2446 > read(7, "", 2674) = 0 > open("/home/virtual/mydomain.com/home/admin/Maildir/.Folders.ALERTS.Payments/cur/1195331425.M52296P11937V0000000000000807I000000001015A5EB_0.tg3,S=2079:2,Sa", O_RDONLY) = 10 > fstat(10, {st_mode=S_IFREG|0600, st_size=2079, ...}) = 0 > pread(10, "Return-Path: <apache(a)tg7.alumina"..., 4096, 0) = 2079 > pread(10, "", 2017, 2079) = 0 > pread(10, "Return-Path: <apache(a)tg7.alumina"..., 4096, 0) = 2079 > write(1, "* 1811 FETCH (UID 1816 RFC822.SI"..., 2180) = 2180 > close(10) = 0 > stat("/home/virtual/mydomain.com/home/admin/Maildir/.Folders.ALERTS.Payments/new", {st_mode=S_IFDIR|0700, st_size=6, ...}) = 0 > stat("/home/virtual/mydomain.com/home/admin/Maildir/.Folders.ALERTS.Payments/cur", {st_mode=S_IFDIR|0700, st_size=618496, ...}) = 0 > close(7) = 0 > open("/home/virtual/mydomain.com/home/admin/Maildir/maildirsize", O_RDWR|O_APPEND) = 7 > read(7, "10485760000S\n1562717408 107547\n-"..., 5120) = 2446 > read(7, "", 2674) = 0 > write(1, "2838 OK Fetch completed.\r\n", 26) = 26 > setsockopt(1, SOL_TCP, TCP_CORK, [0], 4) = 0 > epoll_wait(4, {}, 5, 800) = 0 > epoll_wait(4, {{EPOLLIN, {u32=101056896, u64=2370923004288}}}, 5, 5000) = 1 > read(0, "2839 UID fetch 1817 (UID RFC822."..., 2923) = 51 > setsockopt(1, SOL_TCP, TCP_CORK, [1], 4) = 0 > close(7) = 0 > open("/home/virtual/mydomain.com/home/admin/Maildir/maildirsize", O_RDWR|O_APPEND) = 7 During this time (at least 5-10 minutes) , I could not check the account via my email client Thunderbird. Clicking on an email would just sit there as if it is loading but nothing would happen - the read pane just remains blank. Is Dovecot going through every email (of many 10,000's) and counting up the sizes? Could this be made more efficient so it doesn't lock the account? This could I guess be a Thunderbird issue - it is a disappointingly imperfect client. Dan

[Dovecot] sieve & vacation question
by Ralf Hildebrandt 19 Dec '07

19 Dec '07

We have a setup where a Postfix gateway does virtual_alias rewriting of the envelope sender: ralf.hildebrandt(a)charite.de get rewritten to hildeb(a)postamt.charite.de The mail is then sent on to postamt.charite.de, the Mailbox server. There we use deliver & doecot. The sieve vacation recipient says it won't answer if: "The envelope recipient is not found in the message To:, Cc: or Bcc: fields." But this is never the case, since the envelope is being rewritten. How can I solve this conundrum? -- Ralf Hildebrandt (Ralf.Hildebrandt(a)charite.de) plonk(a)charite.de Postfix - Einrichtung, Betrieb und Wartung Tel. +49 (0)30-450 570-155 http://www.arschkrebs.de The ashtray in my office proudly displays "Designed for Windows98/NT"

[Dovecot] Help please: Migrating Courier imap - Dovecot (Postfix virtual mailbox domains)
by Mark Piekos 17 Dec '07

17 Dec '07

I'm trying to migrate from qmail to postfix. The original server is combo of qmail and Courier imap (no pop mailboxes) I have a working Postfix config and had imap working with Courier imap on the new server. I thought I would experiment with Dovecot as it has some good press. I have moved the contents of my original maildir's to the new server and ste permissions and group membership appropriatley. I can read the 'Inbox' via Dovecot but non of the subfolders that I had configured. I have tried the 'manual' migration method as described in the faq without success (I can see the subfolders but no contents)and have tried running courier-dovecot-migrate.pl witt he same result. I'd be grateful for any advice. Kind regards, Mark.

[Dovecot] v1.1.beta11 deliver crashes when quota exceeded
by arvids 15 Dec '07

15 Dec '07

Hello, v1.1.beta11 deliver crashes when quota exceeded. This also reveals another problem in v1.1.beta11 - imap process does not follow quota settings - this user copied(with imap client) to his imap folder large volume of emails and these emails significantly exceeded quota settings for this user, but imap process did not complain about it. Here is full backtrace of deliver crash: (gdb) bt full #0 0xb7e5dc87 in raise () from /lib/libc.so.6 No symbol table info available. #1 0xb7e5f4f8 in abort () from /lib/libc.so.6 No symbol table info available. #2 0x080ba998 in i_syslog_fatal_handler (type=LOG_TYPE_PANIC, status=0, fmt=0x80ce1c8 "file %s: line %d (%s): assertion failed: (%s)", args=0xbf9e0674 "4W\r\b6") at failures.c:303 backtrace = 0x80e7d20 "/usr/local/dovecot/libexec/dovecot/deliver(i_syslog_fatal_handler+0x2c) [0x80ba98c] -> /usr/local/dovecot/libexec/dovecot/deliver [0x80ba78b] -> /usr/local/dovecot/libexec/dovecot/deliver [0x808c914] "... #3 0x080ba78b in i_panic (format=0x80ce1c8 "file %s: line %d (%s): assertion failed: (%s)") at failures.c:196 args = 0xbf9e0674 "4W\r\b6" #4 0x0808c914 in index_transaction_finish_rollback (t=0x810e210) at index-transaction.c:54 __PRETTY_FUNCTION__ = "index_transaction_finish_rollback" #5 0x0808c758 in index_transaction_rollback (_t=0x810e210) at index-transaction.c:114 itrans = (struct mail_index_transaction *) 0x0 #6 0xb7e2fcf4 in quota_mailbox_transaction_rollback (ctx=0x810e210) at quota-storage.c:113 qt = (struct quota_transaction_context *) 0x810e8c0 #7 0x0805990b in deliver_save (namespaces=0x80f2280, storage_r=0xbf9e0828, mailbox=0x80d8a58 "INBOX", mail=0x80f9c38, flags=0, keywords=0x0) at deliver.c:216 box = (struct mailbox *) 0x80fe048 t = (struct mailbox_transaction_context *) 0x0 kw = (struct mail_keywords *) 0x0 error = 134759821 mailbox_name = 0x80e7af0 "INBOX" ret = <value optimized out> #8 0x0805ac0d in main (argc=Cannot access memory at address 0x58ac ) at deliver.c:954 error_string = <value optimized out> error = <value optimized out> ret = <value optimized out> config_path = 0x80cdb08 "/usr/local/dovecot/etc/dovecot.conf" envelope_sender = 0x80e7030 "arvids(a)mpe.lv" mailbox = 0x80d8a58 "INBOX" auth_socket = <value optimized out> home = <value optimized out> destaddr = 0xbf9e1869 "tests1" user = 0xbf9e1869 "tests1" error = <value optimized out> extra_fields = {arr = {buffer = 0x80e7070, element_size = 4}, v = 0x80e7070, v_modifiable = 0x80e7070} ns = (struct mail_namespace *) 0x80f2280 raw_ns = (struct mail_namespace *) 0x80f22a8 storage = (struct mail_storage *) 0x80f2688 box = (struct mailbox *) 0x80f4a98 input = (struct istream *) 0x80f49b8 t = (struct mailbox_transaction_context *) 0x80f8fc8 headers_ctx = (struct mailbox_header_lookup_ctx *) 0x80f88b8 mail = (struct mail *) 0x80f9c38 process_euid = 95 namespace_pool = <value optimized out> stderr_rejection = false keep_environment = false user_auth = true i = 63 ret = <value optimized out> (gdb) Regards, Arvids

[Dovecot] Xen + NFS
by Eric 14 Dec '07

14 Dec '07

Thanks for Dovecot! I am currently testing several scenarios to help determine how to best implement dovecot for our environment. One scenario of particular interest is Maildir + NFS, load balanced between several servers running dovecot. I am not sure anyone would ever want to implement what I am about to describe here, but none-the-less, I thought I would mention it to the list to see if anyone has had the same experience, or could possibly help. What I am using to _test_ is a single server running RedHat Server 5 + Xen. Dom0 is acting as my NFS server, and a RedHat Server 5 guest running on the same machine is acting as my NFS client and dovecot server. I have a single directory exported from the NFS server which contains several home folders with inboxes stored in Maildir format. The problem I am having is when I open a POP3 connection from a separate machine, I see the following messages on the virtual server in /var/log/maillog and I am unable to retrieve mail: file maildir-uidlist.c: line 139 (maildir_uidlist_unlock): assertion failed: (uidlist->lock_count > 0) and more often: Mailbox init failed top=0/0, retr=0/0, del=0/0, size=0 It appears to be an issue with the login not having the proper permissions to create the dovecot.uidlist file, however, when I log in locally to the dovecot server with the POP3 account, I can read+write in the directory without problems. I suspect that I am missing something simple, but cannot seem to figure it out. dovecot-1.0-1.2.rc15.el5 RedHat Server 5 kernel: 2.6.18-8.1.14.el5xen dovecot -n: shutdown_clients: no login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login login_greeting: Server ready. mail_location: maildir:~/.maildir:INDEX=/var/spool/dovecot/%u maildir_copy_with_hardlinks: yes mbox_write_locks: dotlock fcntl mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 pop3_reuse_xuidl(default): no pop3_reuse_xuidl(imap): no pop3_reuse_xuidl(pop3): yes pop3_lock_session(default): no pop3_lock_session(imap): no pop3_lock_session(pop3): yes auth default: passdb: driver: ldap args: /etc/dovecot-ldap.conf userdb: driver: ldap args: /etc/dovecot-ldap.conf nfs mount options: rw,rsize=32768,wsize=32768,hard,fg,lock,nfsvers=3,tcp,retrans=0,noac --------------------------------- Looking for last minute shopping deals?

[Dovecot] 1.08 + quota-rewrite has no trash plugin
by adam_jh＠hotmail.com 14 Dec '07

14 Dec '07

I think I'm just going to move to 1.1 - however, I'm not keen on installing all the dev tools necessary on a production box. Does anyone have any pointers to web pages or keywords I can check to see what kind of safeguards are needed. The problem I have is building the the srpm to include the quota-rewrite with the trash plugin. I think it has been removed and I wanted to check if anyone knows any good reason not just simply re-enable it (though without the skills I'm not sure I'd do it). -SUBDIRS = acl convert quota imap-quota lazy-expunge mail-log trash $(ZLIB) +SUBDIRS = acl convert quota imap-quota lazy-expunge mail-log $(ZLIB) [root@test ~]# /etc/rc.d/init.d/dovecot start Starting Dovecot Imap: Warning: Corrected permissions for login directory /var/run/dovecot-login FPlugin trash not found from directory /usr/lib/dovecot/imap Error: imap dump-capability process returned 89 Fatal: Invalid configuration in /etc/dovecot.conf [FAILED] A year ago the same question was asked, but I'm not sure of any changes since then. >>> >From tss at iki.fi Sun Oct 15 22:44:38 2006 From: tss at iki.fi (Timo Sirainen) Date: Mon, 16 Oct 2006 00:44:38 +0300 Subject: [Dovecot] Apple Mail quota display In-Reply-To: <C49A984C-F2BF-4A40-84A4-7ED1F7264866(a)mac.com> References: <E94C8EAF-E17E-4E68-B43F-E990A632C4F9(a)mac.com> <1160339709.5137.125.camel@hurina> <C49A984C-F2BF-4A40-84A4-7ED1F7264866(a)mac.com> Message-ID: <1160948678.5448.85.camel@hurina> On Sat, 2006-10-14 at 01:13 -0700, Timothy Martin wrote: > I'm no wiz at applying diffs and compiling my own (i'm a BSD ports > kinda guy) but when i tried that diff i couldn't compile because > there looked to be a couple of lines that should have been removed > and the Trash plugin doesn't appear to be updated to work with the > quota rewrite.
