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. Fois

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

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

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

Progress messages
by Joel Roth 23 Apr '16

23 Apr '16

Hi Dovecot maintainers, I'm maintainer of Net::IMAP::Client, a perl IMAP client library.[1] I've had two bug reports related to Dovecot's in-progress messages.[2,3] While patches have been submitted to resolve both of these bugs, I would like to minimize the possibilty of future breakage. Hence the following questions: 1. Which parts of the RFC are relevant to the in-progress messages? 2. Do you have a list of all of Dovecot's in-progress messages? 3. If, in future, other in-progress messages may be added, can you provide a standard syntax that I may use to strip them from the reply stream. Finally, please CC replies to me, as I am not joined to the list. Thank you for your attention. Joel 1. https://metacpan.org/pod/Net::IMAP::Client 2. https://rt.cpan.org/Public/Bug/Display.html?id=84623 3. https://rt.cpan.org/Public/Bug/Display.html?id=113489 -- Joel Roth

lda_original_recipient_header overrides RCPT TO?
by Gedalya 22 Apr '16

22 Apr '16

Hi all, The example config says: # Header where the original recipient address (SMTP's RCPT TO: address) is taken # from if not available elsewhere. With dovecot-lda -a parameter overrides this. # A commonly used header for this is X-Original-To. #lda_original_recipient_header = I'm using dovecot 2.2.19 The "if not available elsewhere" bit seems to hold true for LDA, but not for LMTP. That is to say, if the value I want used is passed with LDA using the -a option, and another one I want ignored is passed in the header specified in this option, it works correctly and I have the address detail in sieve. However when using LMTP and the desired value is passed as RCPT TO, and this option is defined, and such a header exists -- its value seems to take effect, and is matched by sieve as the envelope address.

problem with Sieve Duplicate Extension when used together with fileinto
by Marco Giunta 21 Apr '16

21 Apr '16

Hi at all, I'm trying to figure out a problem with Sieve Duplicate Extension when used together with fileinto. I use a Dovecot 2.2.23 and Pigeonhole v0.4.13 I have a user (user01) with 3 email addresses (mail01(a)example.com, mail02(a)example.com, user01(a)example.com) I want to discard duplicate, and I want to move email in different folder, so I'm using this sieve script: ---------------------------------------------- require ["fileinto", "duplicate", "imap4flags"]; if duplicate { discard; stop; } if address :is :all "to" "mail01(a)example.com" { fileinto "mail01"; } if address :is :all "to" "mail02(a)example.com" { fileinto "mail02"; } ------------------------------------- To make my test, I have a script that send always the same email; this is an example: ----------------------------------------- Delivered-To: user01(a)example.com Received: from smtp-server.example.com ([192.168.1.214]) by lmtp-server.example.com (Dovecot) with LMTP id YSaBBU53GFdhbwAAIDyJFw for <user01(a)example.com>;

I mean, one time it works (sieve discard 2 duplicate mails), one time it doesn't work at all (sieve doesn't discard any mail), another time it works only for one mail (sieve discards only 1 mail) Here my server log: Apr 21 08:49:07 smtp-server dovecot: lmtp(user01(a)example.com): 1dKXOMl3GFdibwAAIDyJFw: sieve: msgid=<20160421064906.26896.49900(a)myhost.example.com>: stored mail into mailbox 'mail01' Apr 21 08:49:07 smtp-server dovecot: lmtp(user01(a)example.com): 1dKXOMl3GFdibwAAIDyJFw: sieve: msgid=<20160421064906.26896.49900(a)myhost.example.com>: stored mail into mailbox 'mail02' Apr 21 08:49:07 smtp-server dovecot: lmtp(user01(a)example.com): oSM3And3GFdFaQAAIDyJFw: sieve: msgid=<20160421064906.26896.49900(a)myhost.example.com>: marked message to be discarded if not explicitly delivered (discard action) Apr 21 08:49:07 smtp-server dovecot: lmtp(user01(a)example.com): eY00CY93GFcucgAAIDyJFw: sieve: msgid=<20160421064906.26896.49900(a)myhost.example.com>: marked message to be discarded if not explicitly delivered (discard action) Apr 21 08:49:13 smtp-server dovecot: lmtp(user01(a)example.com): dSOyOtV3GFcmdAAAIDyJFw: sieve: msgid=<20160421064913.26904.88802(a)myhost.example.com>: stored mail into mailbox 'mail01' Apr 21 08:49:13 smtp-server dovecot: lmtp(user01(a)example.com): dSOyOtV3GFcmdAAAIDyJFw: sieve: msgid=<20160421064913.26904.88802(a)myhost.example.com>: stored mail into mailbox 'mail02' Apr 21 08:49:13 smtp-server dovecot: lmtp(user01(a)example.com): pSM3And3GFdFaQAAIDyJFw: sieve: msgid=<20160421064913.26904.88802(a)myhost.example.com>: marked message to be discarded if not explicitly delivered (discard action) Apr 21 08:49:13 smtp-server dovecot: lmtp(user01(a)example.com): vZWNOMl3GFcldAAAIDyJFw: sieve: msgid=<20160421064913.26904.88802(a)myhost.example.com>: marked message to be discarded if not explicitly delivered (discard action) Apr 21 08:49:18 smtp-server dovecot: lmtp(user01(a)example.com): eSOyOtV3GFcmdAAAIDyJFw: sieve: msgid=<20160421064918.26911.55371(a)myhost.example.com>: stored mail into mailbox 'mail01' Apr 21 08:49:18 smtp-server dovecot: lmtp(user01(a)example.com): qSM3And3GFdFaQAAIDyJFw: sieve: msgid=<20160421064918.26911.55371(a)myhost.example.com>: stored mail into mailbox 'mail01' Apr 21 08:49:18 smtp-server dovecot: lmtp(user01(a)example.com): qSM3And3GFdFaQAAIDyJFw: sieve: msgid=<20160421064918.26911.55371(a)myhost.example.com>: stored mail into mailbox 'mail02' Apr 21 08:49:18 smtp-server dovecot: lmtp(user01(a)example.com): aSaBBU53GFdhbwAAIDyJFw: sieve: msgid=<20160421064918.26911.55371(a)myhost.example.com>: stored mail into mailbox 'mail01' Apr 21 08:49:18 smtp-server dovecot: lmtp(user01(a)example.com): aSaBBU53GFdhbwAAIDyJFw: sieve: msgid=<20160421064918.26911.55371(a)myhost.example.com>: stored mail into mailbox 'mail02' Apr 21 08:49:18 smtp-server dovecot: lmtp(user01(a)example.com): eSOyOtV3GFcmdAAAIDyJFw: sieve: msgid=<20160421064918.26911.55371(a)myhost.example.com>: stored mail into mailbox 'mail02' Apr 21 08:49:22 smtp-server dovecot: lmtp(user01(a)example.com): rSM3And3GFdFaQAAIDyJFw: sieve: msgid=<20160421064922.26919.68793(a)myhost.example.com>: stored mail into mailbox 'mail01' Apr 21 08:49:22 smtp-server dovecot: lmtp(user01(a)example.com): rSM3And3GFdFaQAAIDyJFw: sieve: msgid=<20160421064922.26919.68793(a)myhost.example.com>: stored mail into mailbox 'mail02' Apr 21 08:49:22 smtp-server dovecot: lmtp(user01(a)example.com): YVCsNPJ3GFd1dgAAIDyJFw: sieve: msgid=<20160421064922.26919.68793(a)myhost.example.com>: marked message to be discarded if not explicitly delivered (discard action) Apr 21 08:49:23 smtp-server dovecot: lmtp(user01(a)example.com): bSaBBU53GFdhbwAAIDyJFw: sieve: msgid=<20160421064922.26919.68793(a)myhost.example.com>: marked message to be discarded if not explicitly delivered (discard action) Apr 21 08:49:27 smtp-server dovecot: lmtp(user01(a)example.com): fSOyOtV3GFcmdAAAIDyJFw: sieve: msgid=<20160421064927.26926.28383(a)myhost.example.com>: stored mail into mailbox 'mail01' Apr 21 08:49:27 smtp-server dovecot: lmtp(user01(a)example.com): sSM3And3GFdFaQAAIDyJFw: sieve: msgid=<20160421064927.26926.28383(a)myhost.example.com>: stored mail into mailbox 'mail01' Apr 21 08:49:27 smtp-server dovecot: lmtp(user01(a)example.com): sSM3And3GFdFaQAAIDyJFw: sieve: msgid=<20160421064927.26926.28383(a)myhost.example.com>: stored mail into mailbox 'mail02' Apr 21 08:49:27 smtp-server dovecot: lmtp(user01(a)example.com): fSOyOtV3GFcmdAAAIDyJFw: sieve: msgid=<20160421064927.26926.28383(a)myhost.example.com>: stored mail into mailbox 'mail02' Apr 21 08:49:27 smtp-server dovecot: lmtp(user01(a)example.com): ZVCsNPJ3GFd1dgAAIDyJFw: sieve: msgid=<20160421064927.26926.28383(a)myhost.example.com>: marked message to be discarded if not explicitly delivered (discard action) As you can see, the message ID of a single sent, is the same, so the duplicate extension should work. If I replace the 'fileinto' rule with, for example, a 'setflag' rule: ----------------------------------------------- require ["fileinto", "duplicate", "imap4flags"]; if duplicate { discard; stop; } if address :is :all "to" "mail01(a)example.com" { setflag "\\seen"; } if address :is :all "to" "mail02(a)example.com" { setflag "\\seen"; } ---------------------------------------------- it works like a charm: for every mail sent, the duplicate extension works. What is it wrong ? someone has any clue ? Cheers, Marco -- Marco Giunta - ITCS SysAdmin Via Bonomea, 265 34136 - Trieste, Italy Tel: +39-040-3787-503 Fax: +39-040-3787-244

Hi there, I have a customer with domain a@tld and domain b@tld. b.tld is an alias for a.tld The Server is using virtual users based on mysql, dovecot for delivery and Maildir for Mail-Storage. If someone writes an e-mail to a.tld with a cc: to b.tld the customer receives the E-Mail twice. Is there a way to deliver the same Mail in the same Mailbox only once ? -- Christoph Adomeit GATWORKS GmbH Reststrauch 191 41199 Moenchengladbach Sitz: Moenchengladbach Amtsgericht Moenchengladbach, HRB 6303 Geschaeftsfuehrer: Christoph Adomeit, Hans Wilhelm Terstappen Christoph.Adomeit(a)gatworks.de Internetloesungen vom Feinsten Fon. +49 2166 9149-32 Fax. +49 2166 9149-10

Module is for different ABI version

Hi, I'm using the Dovecot Prebuilt Binary: deb http://xi.rename-it.nl/debian/ stable-auto/dovecot-2.2 main It seems, that the Prebuilt Binary provided at least once the 2.3 version, because doveconf -n shows: # 2.3.devel (5e7036c): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.devel (ef25ce6) # OS: Linux 3.2.0-4-amd64 x86_64 Debian 7.10 Now Prebuilt Binary provides the 2.2 version again, but I get some error messages on updates: Preparing to replace dovecot-imapd 2:2.2.23-1~auto+14 (using .../dovecot-imapd_2%3a2.2.23-1~auto+16_amd64.deb) ... doveconf: Error: Couldn't load plugin /usr/lib/dovecot/modules/settings/libmanagesieve_login_settings.so: Module is for different ABI version 2.2.ABIv20(2.2.devel) (we have 2.3.ABIv0(2.3.devel)) doveconf: Error: Couldn't load plugin /usr/lib/dovecot/modules/settings/libmanagesieve_settings.so: Module is for different ABI version 2.2.ABIv20(2.2.devel) (we have 2.3.ABIv0(2.3.devel)) and: Preparing to replace dovecot-core 2:2.2.23-1~auto+14 (using .../dovecot-core_2%3a2.2.23-1~auto+16_amd64.deb) ... doveconf: Error: Couldn't load plugin /usr/lib/dovecot/modules/settings/libmanagesieve_login_settings.so: Module is for different ABI version 2.2.ABIv20(2.2.devel) (we have 2.3.ABIv0(2.3.devel)) doveconf: Error: Couldn't load plugin /usr/lib/dovecot/modules/settings/libmanagesieve_settings.so: Module is for different ABI version 2.2.ABIv20(2.2.devel) (we have 2.3.ABIv0(2.3.devel)) After the update doveconf -n shows: # 2.2.devel (8828071): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.devel (ef25ce6) # OS: Linux 3.2.0-4-amd64 x86_64 Debian 7.10 How can I go back to ABI version 2.2?

Foreman component
by Aki Tuomi 20 Apr '16

20 Apr '16

Hi! I am planning to add foreman component to dovecot core and I am hoping for some feedback: Foreman - generic per-user worker handling component It is responsible for managing worker pools per protocol, lifecycle management of workers and handing out instances to others, as in, unix socket connections. Each time a request is made to foreman for a worker, the worker is instantiated (if possible) and locked. Then connection is created to the socket of the worker, and the file descriptor is returned to requestor. When the requestor has completed the task, it's responsibility is to close the DATA channel and also ask foreman to unlock the worker. Components can register new workers using lib-foreman's API. Each worker is registered with struct foreman_worker { const char *protocol; const char *path; const char *version; unsigned int max_instances; unsigned int max_requests; /* how many requests one worker can handle */ unsigned int max_idletime_secs; /* how long worker can idle */ unsigned int max_processtime_secs; /* how long worker can process something */ unsigned int max_lifetime_secs; /* how long a worker can live this can be exceeded if the worker has work to do. */ }; /* minimum lifetime of worker: max_idletime_secs */ /* absolute maximum lifetime of worker: max_lifetime_secs + max_processtime_secs */ The unsigned ints are optional. If they are not defined, the workers are kept until foreman exceeds the total number of workers permitted across pools. Pools are per-worker-class pools, and are generated when a worker is registered. Version specifies the protocol version and is going to be "1000" now. Next version will always be 1001, 1002 etc. Any feedback or questions are welcome! Aki

Reappearing emails (resolved by 2.2.23)

Are you able to reproduce this by running doveadm sync commands manually instead of letting replication do it? For example: > > - doveadm sync -s "" -d -u user@domain > state > - Run the UID STORE & UID MOVE > - doveadm sync -s "`cat state`" -d -u user@domain > > There have been some fixes, especially recentlyhttps://github.com/dovecot/core/commit/950a6e61d6c2dac961ce031bdd8b… sounds a bit similar although I don't really see how it would apply here. Would be a good idea to try anyway with v2.2.22.rc1 (which seems to be stable enough that I'll make v2.2.22 release soon). > > Anyway, I attempted a few times to reproduce it with your test but wasn't able to. We had been running 2 replicating servers (Maildir format) using version 2.2.10 under CentOS 7 in production for quite some time. In this forum, I reported a problem that I traced to a timing problem where unread emails being moved to Trash would magically reappear in the INBOX. I have since upgraded our production servers to 2.2.23. The new version resolved the problem. The version upgrade also resolved the occasional, but annoying, dsync maillog entries "Duplicate file entry at line ...". So, I am a very happy camper and appreciate the feedback.

GSSAPI authentication setup
by Braden McDaniel 20 Apr '16

20 Apr '16

I'm setting up dovecot on a new box; and once again I find myself banging my head against GSSAPI authentication. The particularly irritating thing is that I have this working on another box. I've done my best to ape the configuration of that box; but it's been some years since I set it up and somewhere along the line I have failed. My dovecot.conf has: auth_mechanism = plain gssapi passdb { driver = pam } userdb { driver = ldap args = /etc/dovecot/dovecot-ldap.conf.ext } where /etc/dovecot/dovecot-ldap.conf.ext is: hosts = ldap dn = cn=Manager,dc=endoframe,dc=net dnpass = XXXXXXXX ldap_version = 3 base = ou=people,dc=endoframe,dc=net deref = never scope = subtree user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid user_filter = (&(objectClass=posixAccount)(uid=%u)) I've diff'd the contents of /etc/dovecot on the working vs. non-working servers, and I can see nothing of pertinence (just a few lines about loading the sieve plug-in). Now, logging in with the kerberos password via PAM *is* working. /etc/pam.d/dovecot: #%PAM-1.0 auth sufficient pam_krb5.so account sufficient pam_krb5.so But GSSAPI authentication is not: [ root@hinge ~]# telnet localhost 143 Trying ::1... Connected to localhost. Escape character is '^]'. * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE STARTTLS AUTH=PLAIN AUTH=GSSAPI] Dovecot ready. a authenticate GSSAPI a NO [UNAVAILABLE] Temporary authentication failure. [hinge.endoframe.net:2016-04-16 21:33:32] ^] telnet> close Connection closed. Oh... The kerberos server does have an IMAP service key for hinge; and that service key appears in hinge's /etc/krb5.keytab, as well. Any pointers on where I should be looking at this point would be very much appreciated. -- Braden McDaniel <braden(a)endoframe.com>

sieve vacation: write to the .lda-dupes database without generating a vacation response.
by Bradley M. Kuhn 20 Apr '16

20 Apr '16

I'm using Dovecot's sieve extensions quite happily, they are very good! Thanks for all who worked on them. I have a question that maybe is appropriate for a sieve-specific discussion list, so if there is one I should post to instead, please let me know: I've poked through the sieve vacation RFC and all the documentation I can find and I cannot figure out how to do this. It's more-or-less not the intent of sieve's vacation, so perhaps it's more of a "you can't get there from here" situation, but maybe folks here have an idea: I am (ab)?using sieve vacation to send an automated response at all times to all senders who put me in the To line, every 90 days, which explains my lack of responsiveness and to explain who else might be better contact. (I have hundreds of emails sent to me to which I will never have time to respond, and probably should have been routed to someone else at my organization anyway.) However, I *don't* want my regular correspondents to receive this autoreply. I'd thus like to seed the database with known individuals I'm corresponding with to pretend they've already received the autoresponder. Since I bcc an archive address on all emails, my original thought was to detect people in the To and Cc line of outgoing emails and record them in the .lda-dupes database, as they received a vacation email. I can't figure out how to do this; there is no option on the sieve vacation directive that I can find to do something like this (i.e., I'm looking for a a "do the usual, but *don't* actually send the the email" option on the sieve vacation directive). I do have various other solutions that help in this regard, for example, I never send a vacation email to messages that match: header :contains "In-Reply-To" "@example.org" (where example.org is my domain). This helps, but obviously doesn't handle the situation where the correspondent doesn't reply to one of my emails, or had a stupid MUA. Furthermore, I'd like to implement as many methods as possible for my regular corespondents to limit their receipt of the autoresponder. Any ideas? Thanks in advance for any help or advice you can give! -- -- bkuhn ======================================================================== Become a Conservancy Supporter today: https://sfconservancy.org/supporter

[Dovecot] Patch: 2.0 support for URLAUTH, BURL, CATENATE
by Mike Abbott 18 Apr '16

18 Apr '16

Thank you Timo for beginning the port of URLAUTH, BURL, and CATENATE from 1.2 to 2.0. Attached please find two patches that finish the port to 2.0. One patch updates the dovecot-2.0-urlauth branch and is based on the tip of that branch. The other patch adds the full support to dovecot-2.0.beta5. The resulting URLAUTH/BURL/CATENATE code is the same. Please let me know if you have any questions about these patches. Thanks.

Hi, yesterday I updatet to Dovecot EE version 2:2.2.23.1-1. Now sometimes I see this errors in my logs: ... Apr 18 09:02:19 dovecot1 dovecot: stats: Error: FIFO input error: CONNECT: Duplicate session ID NjcCDoSAFFd/KQAAFMUCeg for user user(a)domain1.com service lmtp Apr 18 09:04:05 dovecot1 dovecot: stats: Error: FIFO input error: CONNECT: Duplicate session ID rjV1HtCGFFcoogAAFMUCeg for user user(a)domain2.com service lmtp Apr 18 09:04:30 dovecot1 dovecot: stats: Error: FIFO input error: CONNECT: Duplicate session ID Sqi0IMWAFFeRNQAAFMUCeg for user user(a)domain3.com service lmtp ... The error only appears when a mail is sent to 2 ore more recipients concurrently. It's not ciritcal for me, all mails are getting delivered correctly. Thanks and regards Urban Loesch
