[Dovecot] Question with versions and problem with IMAP
by Drew Weaver 20 Dec '07

20 Dec '07

General question I have is this. Recently my personal server which I receive e-mail for a domain which is just for playing with rebooted on its own and I had both an RPM version and a source version of dovecot installed on the same machine. The RPM version started first even though I had been running under the source built version up until this point (I originally found that for some reason the version centos built was missing something, maybe plugins, I don't remember now) Anyhow, the question I have is why did it insist that all of my mail was new mail? I quickly realized what the problem is, and I noticed that once I switched it back and forth between the old and new versions it properly updated the 'read vs unread' mail in IMAP, and even though dovecot was using the same configuration file with both binaries (/etc/dovecot.conf) it made such a huge difference. The reason I am asking is because I want to update my source version from 1.0.rc2 to 1.0.9 but I would really like to retain my read vs. unread mail. The RPM version in question is: 0.99.11 The problem I am facing is, today a large mailbox approx. 570M suddenly stopped working via IMAP in outlook express. (again on version 1.0.rc2) no changes have been made to the configuration for over a year. There are no errors in maillog here is the output however: Dec 18 09:49:53 mail dovecot: imap-login: Login: user=<user>, method=PLAIN, rip=client, lip=server Dec 18 09:49:53 mail dovecot: IMAP(user): Effective uid=552, gid=100 Dec 18 09:49:53 mail dovecot: IMAP(user): Loading modules from directory: /usr/local/lib/dovecot/imap Dec 18 09:49:53 mail dovecot: IMAP(user): Module loaded: /usr/local/lib/dovecot/imap/lib01_quota_plugin.so Dec 18 09:49:53 mail dovecot: IMAP(user): Module loaded: /usr/local/lib/dovecot/imap/lib02_imap_quota_plugin.so Dec 18 09:49:53 mail dovecot: IMAP(user): maildir: data=/home/user/Maildir:INDEX=/mailaux/user:CONTROL=/mailaux/user Dec 18 09:49:53 mail dovecot: IMAP(user): maildir: root=/home/user/Maildir, index=/mailaux/user, control=/mailaux/user, inbox= Dec 18 09:49:53 mail dovecot: IMAP(user): fs quota add storage dir = /home/user/Maildir Dec 18 09:49:53 mail dovecot: IMAP(user): fs quota block device = /dev/sda1 Dec 18 09:49:53 mail dovecot: IMAP(user): fs quota mount point = /home Dec 18 09:49:55 mail dovecot: IMAP(user): Disconnected: Logged out Outlook express gives its usually helpful error message: Header download for the 'Inbox' folder did not complete. Account: 'server', Server: 'server', Protocol: IMAP, Server Response: '', Port: 143, Secure(SSL): No, Error Number: 0x800C0148 Any advice on either of these issues would just be great. Happy holidays to those who are celebrating this time of year! -Drew

[Dovecot] Upgrading from 1.0.rc2-1ubuntu2.2 on edgy
by Daragh Mc Grath 20 Dec '07

20 Dec '07

Hi Guys, Can anyone shed some light as to how I upgrade away from 1.0.rc2-1ubuntu2.2 on edgy? The usual aptitude upgrades aren't doing anything for me, and, downloading the package from another Ubuntu release, and trying a dpkg -i is causing lots of dependency errors. Daragh

It passes both endpoints (remote & local) through to dovecot . This lets you restrict smtp-auth just like pop3 or imap using the remote IP. In my case, I had played around with a quick hack for doing per-ip realming (using the local IP) w/ dovecot-sql.

[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?

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 18 Dec '07

18 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 16 Dec '07

16 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
