dsync: Keywords not being replicated
by Karsten Heiken 16 Aug '16

16 Aug '16

I just noticed that some IMAP keywords are not being replicated through dsync backup/sync using Dovecot 2.2.24 from Debian backports: On the master server everything looks fine: RECORD: seq=3, uid=44731, flags=0x09 (Seen Answered) - ext 0 keywords : (0900) <-- 0900 - ext 1 modseq : 701695 (ffb40a0000000000) - ext 3 cache : 3948 (6c0f0000) - ext 4 sort-s : 0 (00000000) On Replica: RECORD: seq=3, uid=44731, flags=0x09 (Seen Answered) - ext 0 keywords : (0000) <-- 0000 - ext 1 modseq : 701695 (ffb40a0000000000) - ext 3 cache : 3948 (6c0f0000) In this case the "forwarded" keyword is gone. Thunderbird no longer displays the message as having been forwarded. The command I used was: > doveadm sync -u myuser -l 60 -N tcp:replica:24245 My config is attached. It looks like there are other users also having the same problem: http://dovecot.org/list/dovecot/2016-January/102951.html Thanks, Karsten -- Karsten Heiken Leibniz Universität IT Services Kommunikationssysteme E-Mail, XMPP, Kalender Schloßwender Str. 5 D-30159 Hannover

[Dovecot] How to disable SSL and TLSv1.1?
by Darren Pilgrim 16 Aug '16

16 Aug '16

I'm running Dovecot 2.2.5 and want to make it refuse SSLv2, SSLv3 and TLSv1.0. Clients will opportunistically use TLS 1.1 and 1.2, but now I want require they do so. Is it enough to set ssl_cipher_list = HIGH:!SSLv2:!SSLv3:!TLSv1.0:!aNULL:!MD5 or are there additional settings I need to specify?

public namespace quota
by Chris 15 Aug '16

15 Aug '16

All, sorry, I've to ask again. I'm trying to define quotas for public namespace subfolders: ns=public/ - DepartmentA - 50G - DepartmentB - 500M - DepartmentC - 10G public/ shouldn't have a limit. public/DepartmentA is independent of B and C. Is this possible with dovecot? I've added the following rules quota = maildir:User quota quota2 = maildir:Public quota:ns=public/ quota2_rule = *:storage=10M quota2_rule2 = DepartmentA:storage=+50M but then only 10M is shown for DepartmentA in Thunderbird. I'm using Maildir++. maildirsize is only created in public/ toplevel, not in public/DepartmentA. Public-subfolders are owned by vmail system-user. Different virtual users' ACLs are set (and working). Any help is appreciated! - Chris

Symbolic link for sieve script not created by dsync
by Laz C. Peterson 15 Aug '16

15 Aug '16

Hello Dovecot ~ I know this bug has been discussed previously for other versions of dsync, pigeonhole and dovecot … But we still can’t get dsync to create the symbolic link for the sieve script after it is created on a replicated server. We are running Ubuntu 16.04.1 with the official Ubuntu dovecot packages (2.2.22). Sieve script itself is replicated, but not the symbolic link. Any suggestions? ~ Laz Peterson Paravis, LLC

fts-solr autoindex issue in public mailbox
by maks 15 Aug '16

15 Aug '16

Hello everyone, I have a public mailbox: /var/mail/example.com/public/public_mailbox with "Public/" namespace set up in config file. When i move message from user's INBOX to one of mailboxes inside Public/ (for example Public/archive), i'm getting "indexer-worker: Info: Indexed 0 messages in Public/archive" in logs and i can't find the message through the FTS search. If i move the message back from Public/archive into personal mailbox the message is indexed by indexer-worker "indexer-worker: Info: Indexed 1 messages in temp_folder" If i perform "doveadm index Public/archive" then the message is added to the index. Dovecot version: 2.2.9 FTS backend: Solr fts_autoindex = yes Searching through localhost:8983/solr/collection1 gives the same result.

Bug with shared access to mailbox
by van der Kamp, John 15 Aug '16

15 Aug '16

Hello, I'm testing dovecot with some setups, and one of them is with shared mailboxes. The test I wrote will create and delete mail using multiple connections to the same user and folder. Each connection makes a couple of mails, remembers the uid from APPENDUID, and will delete those emails again. At the end of the test I expect an empty folder. This is not what happens. At the end I still have several mails in the folder. I lack insight in the dovecot source to tell exactly what's going on. I've tested this with different setups: 1) local system user, connecting over localhost -> bug is present 2) local system user, connecting over internet -> bug is present, but is harder to reproduce 3) dovecot as proxy to another imap server -> bug is present In step 3, you can even setup a dovecot to be a proxy to another dovecot server. >From logging in the other imap server I've seen that a client command to the proxy like: TAG UID STORE 1:3 +FLAGS (\Deleted) TAG UID EXPUNGE 1:3 will be sent to the other imap server in 3 steps, one for each message. When running the test with multiple threads, that logging shows that some uids are never sent to the other imap server, and some uids are sent over different connections than they original were sent to. (Thread 1 deletes 1:3, Thread 2 deletes 4:6, the proxy of Thread 1 might expunge messages from Thread 2 and vice versa). Attached is a python script which tests the behavior. The script expects a file named "testmail.eml" to upload to the imap server. I used an email which was about 75 kB. I tested using version: 2.2.22 (fe789d2). Let me know if I can help in any other way too. John

Save user passwords in clear text
by Lefteris Tsintjelis 13 Aug '16

13 Aug '16

Is it possible to save user passwords as clear text through dovecot? I am currently using MD5 passwords and I allow only "plain and login” mechanisms but I want to switch my database to clear text as this will give me the ability to use more mechanisms such as CRAM-MD5. Is this possible? Thank you
