public namespace quota
by Chris 16 Aug '16

16 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

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

Hi, currently I am putting all my filter strings into a big array in my sieve script. I wonder whether this is the best way to store many criteria.

receiving and associating emails to single a/c
by David Tildesley 13 Aug '16

13 Aug '16

Hi,Looking for advice.Scenario: we have a dmz mta that currently redirects received emails for a selection of email domains to specific internal ms exchange servers. We want this mta to redirect incoming customer emails directed to a set of email addresses numbering about 30, to a dovecot server and associate these emails to a single dovecot user account so that a contact Centre platform can pull these emails on a frequent cycle.How to go about configuring this on the dovecot? I assume a postfix server needs to be installed on the dovecot server for the dmz mta to send these emails to dovecot inbox? Any advice most appreciated. David. Sent from Yahoo Mail on Android

Dovecot Director self ip
by Tomaž 12 Aug '16

12 Aug '16

Hello everybody! I kindly ask somebody to help me with this problem. I'm trying to configure Dovecot proxy with Director. On the same machine is KeepAlived that needs this configured to bind non local IP: sysctl net.ipv4.ip_nonlocal_bind=1 But as already mentioned in this email: http://www.dovecot.org/list/dovecot/2012-November/087033.html Dovecot Director needs sysctl net.ipv4.ip_nonlocal_bind=0 (if this is set, everything works ok, but we break keepalived) because otherwise the second server uses IP from the first server as "self". Is it possible to configure this some other way, so Dovecot Director doesn't try to bind to all IPs and because of above configuration, uses the first one that binds. This is the result from director status on server 1: root@u1:~# doveadm director ring status director ip port type last failed status 172.16.100.191 9090 self never handshaking 172.16.100.192 9090 never handshaking and server 2: root@u2:/var/log# doveadm director ring status director ip port type last failed status 172.16.100.191 9090 self never handshaking 172.16.100.192 9090 never My dovecot config: http://pastebin.com/RnmHRWhY Thank you very much!

dovecot 2.2.25 & deleting emails from \Junk special-use assigned folder
by Marc Jauvin 11 Aug '16

11 Aug '16

Since our cPanel installation upgraded Dovecot from 2.2.23 to 2.2.25, deleting emails located in the Junk folder (\Junk special-use), the emails end-up in the \Trash special-use folder instead of being purged as before. Is there something that changed or this some configuration I am missing? Thanks for any help regarding this. -- Marc Jauvin Register4less, Inc. 514-905-6500 x403

I have a ton of these errors in my logs: Aug 11 14:16:04 imap(xxxx(a)xxxxx.xxxx): Error: Corrupted index file...../dovecot.list.index: Header's corrupted flag is set Does Dovecot not automatically fix these? Or what is the correct action to take? -- Tom
