Dovecot panic for one user after upgrading
by Owen B. Mehegan 04 Jan '18

04 Jan '18

The EC2 instance that I run Dovecot on (personal mail server) was forcibly "retired" yesterday, and as a result I ended up rebuilding from backups. In the process I switched from Ubuntu Precise to Ubuntu Xenial (12.04 to 16.04), and this in turn caused me to upgrade Dovecot from 2.0.19 to 2.0.22. Now, although accessing mail seems to work OK using my various clients, I am seeing these errors in my logs: Jan 3 05:56:58 -- dovecot: imap(owen): Panic: file mail-index-sync-keywords.c: line 227 (keywords_update_records): assertion failed: (data_offset >= sizeof(struct mail_index_record)) Jan 3 05:56:58 -- dovecot: imap(owen): Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(+0x7aee2) [0x7fe9c08dbee2] -> /usr/lib/dovecot/libdovecot.so.0(+0x7afcd) [0x7fe9c08dbfcd] -> /usr/lib/dovecot/libdovecot.so.0(i_fatal+0) [0x7fe9c0880a61] -> /usr/lib/dovecot/libdovecot-storage.so.0(mail_index_sync_keywords+0x828) [0x7fe9c0c1fdd8] -> /usr/lib/dovecot/libdovecot-storage.so.0(mail_index_sync_record+0xef) [0x7fe9c0c2079f] -> /usr/lib/dovecot/libdovecot-storage.so.0(mail_index_sync_map+0x238) [0x7fe9c0c21758] -> /usr/lib/dovecot/libdovecot-storage.so.0(mail_index_map+0x71) [0x7fe9c0c18de1] -> /usr/lib/dovecot/libdovecot-storage.so.0(+0xd28fd) [0x7fe9c0c2e8fd] -> /usr/lib/dovecot/libdovecot-storage.so.0(+0xd2f03) [0x7fe9c0c2ef03] -> /usr/lib/dovecot/libdovecot-storage.so.0(mail_index_open+0x78) [0x7fe9c0c2efe8] -> /usr/lib/dovecot/libdovecot-storage.so.0(index_storage_mailbox_open+0x92) [0x7fe9c0c08042] -> /usr/lib/dovecot/libdovecot-storage.so.0(+0x5e8d2) [0x7fe9c0bba8d2] -> /usr/lib/dovecot/libdovecot-storage.so.0(+0x5e9b8) [0x7fe9c0bba9b8] -> /usr/lib/dovecot/libdovecot-storage.so.0(+0x37b86) [0x7fe9c0b93b86] -> /usr/lib/dovecot/libdovecot-storage.so.0(mailbox_open+0x20) [0x7fe9c0b93d00] -> /usr/lib/dovecot/libdovecot-storage.so.0(index_storage_get_status+0x20) [0x7fe9c0c073b0] -> /usr/lib/dovecot/libdovecot-storage.so.0(mailbox_get_status+0x37) [0x7fe9c0b940e7] -> dovecot/imap(imap_status_get+0x77) [0x55d3b4c3f977] -> dovecot/imap(cmd_status+0x1a9) [0x55d3b4c32969] -> dovecot/imap(command_exec+0x9c) [0x55d3b4c3806c] -> dovecot/imap(+0x193e2) [0x55d3b4c363e2] -> dovecot/imap(+0x1946c) [0x55d3b4c3646c] -> dovecot/imap(client_handle_input+0x165) [0x55d3b4c36825] -> dovecot/imap(client_input+0x82) [0x55d3b4c36db2] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x4c) [0x7fe9c08efc6c] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run_internal+0x101) [0x7fe9c08f1101] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0x25) [0x7fe9c08efcf5] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_run+0x38) [0x7fe9c08efe98] Jan 3 05:56:59 -- dovecot: imap(owen): Fatal: master: service(imap): child 18289 killed with signal 6 (core dumped) I have deleted the dovecot.* files in the Maildir for all users (did this while Dovecot was stopped, then started it again), but the errors persist.

dovecot v2.3.0: imap segfault when sieve_extprograms_plugin.so called
by Rhys Williams 03 Jan '18

03 Jan '18

Hi, I have recently upgraded to dovecot v2.3 on Ubuntu 16.04.3 from repo.dovecot.org and I switched to IMAPSieve for rspamd with the guide from the wiki. When a mail is moved from Junk to another Inbox or vice-versa imap segfaults. I have posted debug logs and versions below, any help will be greatly appreciated. Thanks, Rhys Williams lux@bifrost:~$ dovecot --version 2.3.0 (c8b89eb) lux@bifrost:~$ uname -a Linux bifrost 4.10.0-43-generic #47~16.04.1-Ubuntu SMP Wed Dec 13 19:23:27 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux Log of the crash: https://paste.ubuntu.com/26314370/ (https://paste.ubuntu.com/26314370/) Core dump: https://paste.ubuntu.com/26314349/ (https://paste.ubuntu.com/26314349/) dovecot -n: https://paste.ubuntu.com/26314365/ (https://paste.ubuntu.com/26314365/)

sieve - Failed to store into mailbox 'INBOX/${1}': Mailbox doesn't exist: INBOX/${1}
by Ludovic Terrier 02 Jan '18

02 Jan '18

Hello, First of all, happy new year! I’ve recently configured my mail server and was using a simple sieve rule in order to store all my ‘user+pattern(a)example.xn--com-to0a ingoing email to be stored in the INBOX/pattern folder. This setup worked very well. I restarted my server this morning (don’t know if it’s related…) and since Dovecot keep storing my emails in INBOX with following errors: root@server:~# cat /var/mail/vhosts/example.com/ludovic/.dovecot.sieve.log sieve: info: started log at Jan 01 12:13:56. error: msgid=<20180101111353.C332C25386(a)server.example.com>: failed to store into mailbox 'INBOX/${1}': Mailbox doesn't exist: INBOX/${1}.

dovecot-pigeonhole problems after upgrade to v2.3.0
by Fabian A. Santiago 02 Jan '18

02 Jan '18

Hello, After upgrading to dovecot 2.3.0, my sieve filtering is broken. I managed it via roundcube's managesieve plugin. my emails are not being filtered accordingly into their folders and when i attempt to access the filter interface in roundcube, my maillog reports: Dec 28 12:05:07 mail roundcube: <gs7miohh> PHP Error: Unable to connect to managesieve on 127.0.0.1:4190 in /var/www/roundcubemail/plugins/managesieve/lib/Roundcube/rcube_sieve_engine.php on line 222 (GET /mail/?_task=settings&_action=plugin.managesieve) Dec 28 12:05:07 mail roundcube: ERROR: Not currently in AUTHORISATION state (1) Dec 28 12:05:07 mail httpd: ERROR: Failed to write to socket: connection lost () Now I'm willing to consider the possibility that the RC plugin doesn't work with v2.3.0 of dovecot sieve but why wouldn't my current sieve filters be functional? -- Thanks, Fabian S.

Dbox and NVMe drives
by Andrew 02 Jan '18

02 Jan '18

Hi all, We're looking at replacing our existing NFS setup and using local storage on multiple nodes - using Director to send clients to the correct node. We have about 10,000 mailboxes using about 6TB at the moment, a mix of IMAP and POP, probably 65% IMAP. I'm thinking of moving from Maildir to Dbox; using 2TB NVMe drives in RAID1 as primary storage and 4x 6TB SATA disks in RAID10 for altstorage and probably smaller SATA SSDs in RAID1 for the indexes. I guess my question is, have other people had bad experiences with flash based storage on medium sized mail servers and does splitting the storage like these seem sensible for Dbox in terms of maximizing performance? Thanks! S.

Sieve can't move messages in a public namespace
by Paolo 02 Jan '18

02 Jan '18

Hello, my dovecot version is 2.1.17 I've configured some public namespaces (config attached). When a mail arrives at a certain mail address, that mail is handled by dovecot lmtp server and a sieve script is executed that shuold move the message in one of the namespaces. This is the script: require "fileinto"; if header :contains "From" "example(a)example.com" { fileinto :create "Cond-UFF_FORNITORI/CONTABILITA/Inviata"; } else { fileinto :create "Cond-UFF_FORNITORI/CONTABILITA/Ricevuta"; } The problem is that the sieve script fails with the error: sieve: info: started log at Jun 27 12:42:28. error: msgid=<c9154db4-ff68-52a3-2639-11f09f225f68(a)fcr.re.it>: failed to store into mailbox 'Cond-UFF_FORNITORI/CONTABILITA/Ricevuta': Mailbox doesn't exist: Cond-UFF_FORNITORI/CONTABILITA/Ricevuta. I double checked config, dovecot documentation, sieve documentation, ACL, filesystem paths, filesystem permissions, etc. etc. I'm pretty sure it's all right. So why isn't sieve working? Thanks if you bother to answer & Cheers Paolo

dovecot-submission SMTP send error with Thunderbird (BODY=8BITMIME)
by Reuben Farrelly 02 Jan '18

02 Jan '18

Hi, With latest 2.3 -git (and 2.3.0 release), I'm running into this error with Thunderbird: "An error occurred while sending mail. The mail server responded: 5.5.4 Unsupported mail BODY type. Please verify that your email address is correct in your account settings and try again." This is fatal and means Thunderbird cannot use the submission service - fortunately I can revert back to a native Postfix service which works.

Curiously enabling rawlog doesn't capture this error, which is why I used tcpdump above.

I would have expected it to capture the full conversation log including any protocol errors and failures like this. Reuben

Email1(a)domain.tlf > ? Email2(a)domain.tld > ? Email3(a)domain.tld Others have suggested a postfix method. You can also pipe it to a script that will select a destination to forward to alias "info(a)domain.tld" to "|/my/selector|script". This will work both in Postfix, sendmail, and probably most other MTAs. If you actually want randomization (rather than sequential round-robin), you can simplify because you won't need to record the last delivery. Use /dev/urandom or unix time() mod 3 to select forwarding address. Joseph Tam <jtam.home(a)gmail.com>
