Strange search behavior
by Cornelius Charlie 26 Apr '16

26 Apr '16

Hello, I experienced a strange behavior in the way dovecot is performing searches, I only experienced this exact issue with the flag "seen". If I perform this command: UID SORT (SIZE) UTF-8 FLAGGED SEEN Dovecot return every seen messages even if the message is not "flagged'. This is only happening when there is no unseen messages in the mailbox, if there is at least one, this is working properly. Any though ? Thanks.

push-notification plugin and imap-metadata permissions
by Giovanni S. Fois 26 Apr '16

26 Apr '16

Ultra short version: Why cant I set the following mailbox metadata key? /private/vendor/vendor.dovecot/pvt/server/vendor/vendor.dovecot/http-notify Let me explain the context: I'm using the Dovecot version 2.23.1, but the same happens for the 2.2.22 The push-notification plugin is supposed to send out a notification whenever a mailbox get a new email message. In order to tell if a mailbox is enabled to send out the notification, the plugin looks out for the following mailbox metadata key: /private/vendor/vendor.dovecot/pvt/server/vendor/vendor.dovecot/http-notify If the key is set then everything is OK and the notification is sent, otherwise the action is skipped. If I try to setup the metadata key by hand (telnet as the user over the imap port): setmetadata INBOX (/private/vendor/vendor.dovecot/pvt/server/vendor/vendor.dovecot/http-notify "user=myuser(a)mydomain.com") I get the error message: "Internal mailbox attributes cannot be accessed" Digging in the Dovecot 2.2.22 sources i found that: This string is from lib-imap-storage/imap-metadata.c - line 36 - Dovecot 2.2.22 The message is triggered by the following condition - same file - line 125 - Dovecot 2.2.22 if (strncmp(*key_r, MAILBOX_ATTRIBUTE_PREFIX_DOVECOT_PVT, strlen(MAILBOX_ATTRIBUTE_PREFIX_DOVECOT_PVT)) == 0) { So the path pvt/server appears to be forbidden. But, in the file lib-storage/mailbox-attribute.h we can read the following comment: /* User can get/set all non-pvt/ attributes and also pvt/server/ (but not pvt/server/pvt/) attributes. */ And, after said comment there is the definition of the macro MAILBOX_ATTRIBUTE_KEY_IS_USER_ACCESSIBLE(key) which has the same basic function of the condition in imap-metadata.c , but in this case the same imap key is seen as accessible. Now my questions: Can we use a negated version of MAILBOX_ATTRIBUTE_KEY_IS_USER_ACCESSIBLE(key) in imap-metadata? How can the push-notification plugin work out-of-the-box without changes and recompilation? Thank you for your valuable time and forgive me if I'm posing a dumb question. Best wishes, Giovanni S.

Kernel panic in dovecot-ee-lmtp on Debian 8
by Tobi 26 Apr '16

26 Apr '16

Hi list I just realized that that I don not receive all mails in my mailbox (running dovecot-ee 2.2.23.1-1 on Debian 8). On my frontend servers (running postfix) the queue fills up with mails that cannot be delivered via lmtp to my backend servers. The error message on the frontend is "lost connection with backend while sending data" When I checked the logs on the backend server I found upon every delivery attempt kernel panics Apr 25 12:33:36 mbox1 dovecot: lmtp(REDACTED): Panic: epoll_ctl(del, 18) failed: Bad file descriptor Apr 25 12:33:36 mbox1 dovecot: lmtp(REDACTED): Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(+0x85dee) [0x7faa19225dee] -> /usr/lib/dovecot/libdovecot.so.0(+0x85edc) [0x7faa19225edc] -> /usr/lib/dovecot/libdovecot.so.0(i_fatal+0) [0x7faa191ca5be] -> /usr/lib/dovecot/libdovecot.so.0(+0x9afc1) [0x7faa1923afc1] -> /usr/lib/dovecot/libdovecot.so.0(+0x994af) [0x7faa192394af] -> /usr/lib/dovecot/libdovecot.so.0(+0xa5eda) [0x7faa19245eda] -> /usr/lib/dovecot/libdovecot.so.0(+0xa4566) [0x7faa19244566] -> /usr/lib/dovecot/libdovecot.so.0(o_stream_destroy+0xe) [0x7faa192446ee] -> /usr/lib/dovecot/libdovecot-sieve.so.0(+0x7e44b) [0x7faa17d3a44b] -> /usr/lib/dovecot/libdovecot-sieve.so.0(+0x7ea14) [0x7faa17d3aa14] -> /usr/lib/dovecot/libdovecot.so.0(+0xa6d88) [0x7faa19246d88] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x4c) [0x7faa19239c6c] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run_internal+0x101) [0x7faa1923b0d1] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0x25) [0x7faa19239cf5] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_run+0x38) [0x7faa19239e98] -> /usr/lib/dovecot/libdovecot-sieve.so.0(program_client_run+0xe8) [0x7faa17d3b308] -> /usr/lib/dovecot/modules/sieve/lib90_sieve_extprograms_plugin.so(+0x45b8) [0x7faa15d855b8] -> /usr/lib/dovecot/libdovecot-sieve.so.0(sieve_interpreter_continue+0x7c) [0x7faa17cfa2ac] -> /usr/lib/dovecot/libdovecot-sieve.so.0(sieve_interpreter_run+0x2b) [0x7faa17cfa4cb] -> /usr/lib/dovecot/libdovecot-sieve.so.0(+0x519e0) [0x7faa17d0d9e0] -> /usr/lib/dovecot/libdovecot-sieve.so.0(sieve_execute+0x47) [0x7faa17d0e567] -> /usr/lib/dovecot/modules/lib90_sieve_plugin.so(+0x3b6b) [0x7faa17f73b6b] -> /usr/lib/dovecot/libdovecot-lda.so.0(mail_deliver+0x49) [0x7faa197e5849] -> dovecot/lmtp() [0x4064b3] -> dovecot/lmtp() [0x406cb4] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x4c) [0x7faa19239c6c] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run_internal+0x101) [0x7faa1923b0d1] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0x25) [0x7faa19239cf5] Apr 25 12:33:36 mbox1 dovecot: lmtp(REDACTED): Fatal: master: service(lmtp): child 32081 killed with signal 6 (core dumps disabled) the weird thing is that this is not concerning all incoming mails.

It arrived via a frontend that has other mails in queue that could not be delivered so far. Does anyone have an idea where I could look for the root cause of this panic messages? Thanks a lot tobi

doveadm-server segfaults when searching or expunging with the -A flag
by Burak Seydioglu 26 Apr '16

26 Apr '16

Hello, I have an openldap backend that contains a large number of users and serves passdb and userdb requests. I was trying to work around the pop3 deletion issue that I had reported earlier (http://www.dovecot.org/list/dovecot/2016-April/103973.html) with the pop3_deleted_flag setting so I updated my configuration and created some background jobs to expunge deleted emails. However, doveadm-server segfaults when running search or expunge commands with the -A flag: doveadm search mailbox INBOX KEYWORD '$Pop3Deleted' -A doveadm expunge mailbox INBOX KEYWORD '$Pop3Deleted' -A ###################################### gdb /usr/libexec/dovecot/doveadm-server /var/crash/core-doveadm-server-11-0-0-2589-1461628665 #0 o_stream_cork (stream=0x0) at ostream.c:141 #1 0x0000000000430193 in server_connection_output (conn=0xfe10e0) at server-connection.c:126 #2 0x00007fcde9fc80c7 in plain_flush_callback (sstream=0xfdacf0) at ostream-openssl.c:180 #3 0x00007fcdeb6f9929 in stream_send_io (fstream=0xfe65e0) at ostream-file.c:482 #4 0x00007fcdeb6ebceb in io_loop_call_io (io=0xfdb110) at ioloop.c:564 #5 0x00007fcdeb6ed2e7 in io_loop_handler_run_internal (ioloop=<value optimized out>) at ioloop-epoll.c:220 #6 0x00007fcdeb6ebd95 in io_loop_handler_run (ioloop=0xfdf4b0) at ioloop.c:612 #7 0x00007fcdeb6ebf38 in io_loop_run (ioloop=0xfdf4b0) at ioloop.c:588 #8 0x000000000041f542 in dsync_connect_tcp (ctx=0xfc7d70, mail_set=<value optimized out>, target=<value optimized out>, ssl=true, error_r=0x7ffde6127020) at doveadm-dsync.c:806 #9 0x000000000041ff95 in parse_location (_ctx=0xfc7d70, service_user=<value optimized out>, error_r=0x7ffde6127020) at doveadm-dsync.c:837 #10 cmd_dsync_prerun (_ctx=0xfc7d70, service_user=<value optimized out>, error_r=0x7ffde6127020) at doveadm-dsync.c:903 #11 0x00000000004205f2 in doveadm_mail_next_user (ctx=0xfc7d70, cctx=<value optimized out>, error_r=0x7ffde6127020) at doveadm-mail.c:383 #12 0x000000000043151f in doveadm_mail_cmd_server_run (conn=0xfc3950) at client-connection.c:183 #13 doveadm_cmd_handle (conn=0xfc3950) at client-connection.c:266 #14 client_handle_command (conn=0xfc3950) at client-connection.c:330 #15 client_connection_input (conn=0xfc3950) at client-connection.c:444 #16 0x00007fcdeb6ebceb in io_loop_call_io (io=0xfc34f0) at ioloop.c:564 #17 0x00007fcdeb6ed2e7 in io_loop_handler_run_internal (ioloop=<value optimized out>) at ioloop-epoll.c:220 #18 0x00007fcdeb6ebd95 in io_loop_handler_run (ioloop=0xf90780) at ioloop.c:612 #19 0x00007fcdeb6ebf38 in io_loop_run (ioloop=0xf90780) at ioloop.c:588 #20 0x00007fcdeb684753 in master_service_run (service=0xf90620, callback=<value optimized out>) at master-service.c:640 #21 0x0000000000433897 in main (argc=1, argv=0xf903a0) at main.c:126 ###################################### Dovecot version ###################################### dovecot --version 2.2.23 (806d709) ###################################### doveconf -n ###################################### #

doveadm backup 2.2.23 ignores -u, but reads USER environment?
by Heiko Schlittermann 26 Apr '16

26 Apr '16

Hi, during a migration (cyrus -> dovecot) we ran into trouble¹ using 'doveadm backup' with 2.2.9. So I built 2.2.22 and 2.2.23, but they expose quite different behaviour. 2.2.22 seems to work at least partially, but 2.2.23 complains about a non existing user (root?). The command I'm running is: doveadm -o pop3_uidl_format=%v.%u \ -o imapc_master_user=cyrus -o imapc_password=* -o imapc_host=* \ -o mail_fsync=never \ -o imapc_ssl_verify=no -o imapc_ssl=imaps -o imapc_port=993 \ backup -f -u heiko -R imapc: Using 2.2.9 or 2.2.22 it works, using 2.2.23 "-u …" is ignored and I've to pass the user via the USER environment. But according to the manpage of doveadm-sync -u user/mask Run the command only for the given user. It's also possible to use '*' and '?' wildcards (e.g. -u *(a)example.org) When neither the -A option, nor the -F file option, nor the -u user was specified, the command will be executed with the environment of the currently logged in user. Interestingly enough -u 'heiko*' works fine, even with USER=root. So the environment doesn't seem to override -u … always. Maybe an important side note: the user 'heiko' doesn't exist as a local system user, he is known via LDAP only. And for e.g. 'doveadm quota -u heiko' it works as expected, even with 2.2.23. ¹) solved meanwhile by using -o mail_plugins= as the quota plugin seems to crash 'doveadm backup' Best regards from Dresden/Germany Viele Grüße aus Dresden Heiko Schlittermann -- SCHLITTERMANN.de ---------------------------- internet & unix support - Heiko Schlittermann, Dipl.-Ing.

Setting up replication?

Moving to as new server
by Jerry 25 Apr '16

25 Apr '16

I will shortly have to replace the OS on my machine. For various reasons, I will not be able to use a program like “imapsync” to transfer my documents to a new server. All of the mail folders on my present PC are stored under “/var/mail/vmail”. If I copied all of the folders under “vmail” and moved them to the new PC, would Dovecot be able to access them normally? Dovecot would not be running while I moved the files. Thanks

expunging messages doesn't update maildirsize
by WJCarpenter 24 Apr '16

24 Apr '16

This might be something that everybody thinks of as a well-known fact, but I've been searching around quite a bit without finding anything definitive. Maybe I just have the wrong idea of what's supposed to be going on. I'm using maildir+ quotas. For arriving mail, it works as I expect: new lines are appended to maildirsize to reflect the size of the new messages. But I also expected that mail that is deleted (and expunged, yes totally gone from the disk drive, verified from the command line) would lead to some kind of update to maildirsize or maybe even a complete recalculation. But that does not happen on my system (dovecot 2.2.9 on a Ubuntu variant). Now, I know that I can run "doveadm" from a cron job or whatever to have the maildirsize info recomputed. I also know that the maildirsize file will be recreated when it gets larger than 4k. That's all fine. But I don't see why I should have to have this out-of-band cron job, and I don't see why my users should have to wait if their maildirsize file doesn't tip over the magical 4k mark (which is a lot of individual messages being recorded). Is it by design that dovecot doesn't update maildirsize immediately when messages are expunged? If yes, why?

Redirect indicator issue in Maildir flag seems to be an issue [missing?]
by Andrew McGlashan 23 Apr '16

Hi, I've got an issue with the latest Thunderbird, although I'm not sure this is when the problem started (version 45.0) it has an add-on "mailredirect (version 0.8.7)". In the past I've been able to redirect mail (bounce them) and I get a nice little green arrow like indicator (in TB) to show that I redirected the particular email. Now, that green arrow appears briefly, then it goes away and I can no longer tell by looking at my email list if the email has, in fact, been bounced or not. I suspect it is dovecot on the Debian server: dovecot-common 1:2.1.7-7+deb7u1 dovecot-core 1:2.1.7-7+deb7u1 dovecot-imapd 1:2.1.7-7+deb7u1 dovecot-pop3d 1:2.1.7-7+deb7u1 It isn't just Thunderbird though, as I just tried to redirect using a Squirrelmail plugin, and it gives me the same problem; so I don't think it is at the MUA end of the deal. It /may/ be that TB is setting the flag and resetting it or dovecot is resetting it.... Any ideas? Nobody else has seen this yet? Thanks AndrewM

Maildir P flag?
by Andrew McGlashan 23 Apr '16

Hi, I use Thunderbird with a mailredirect addon. It used to show me which emails were redirected. I believe it used the "P" Maildiir flag for this status. Now it seems that none of my email store has any file with a flag of P. Is this something that dovecot may have adjusted with my mail store? And if so, why? If not, any ideas where I might look for the next "culprit"? ;-) Thanks AndrewM
