Thunderbird version 45 no longer can login via SSL
by CJ Keist 22 Apr '16

All, Just ran into issue with the latest Thunderbird release today, version 45.0. This version will no longer login to our dovecot 1.2.17 version. I now this is old version but wanting to know if there is anyone finding a solution to this? Right now our work around is to reinstall Thunderbird version 38.7.2 Thanks... -- C. J.

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.

Hi, first of all, many thanks for a great piece of software. Today I updated one of our 2 IMAP/POP3 proxies from version 2.2.15.17-1 to 2.2.23.1-1 (both are enterprise editions).

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

Deliver same E-Mail in same Mailbox only once ?
by Christoph Adomeit 21 Apr '16

21 Apr '16

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
