Renaming directories with subdirectories over IMAP
by Зинин Дмитрий Андреевич 10 Dec '14

Hi, I¹ve a problem with renaming directories with subdirectories. In root directory I create directory named ³lvl1² with subdirectory ³lvl2² When I rename directory lvl1 to lvl1-new I get: 1. /lvl1-new with subdir lvl2 but I can use only /lvl1-new and not /lvl1-new/lvl2 2. /lvl1 with subdir lvl2 but I can use only /lvl1/lvl2 and not /lvl1 Is it a feature or a bug? If bug is there a fix? PS: CentOS 6.6 and Dovecot 2.0.9-7 from official repository with all updates. Best regards, Dmitriy

Required SSL with exceptions

I have a Dovecot cluster which is on separate machines from my webmail/caldav/cardav cluster, and I currently have the system setup with ssl = required. Unfortunately the caldav/cardav server I am running doesn't support STARTTLS so I was wondering if there is a way to still enforce ssl for every connection with the exception of a certain subnet, or if there is a better way to accomplish this without install a local install of Dovecot on each of my caldav/cardav servers.

Using dovecot with existing mbox hieararchy - possible?
by Chris Green 08 Dec '14

I currently use mutt to read my E-Mail on a machine which runs a postfix server to receive mail by SMTP. Mail is actually delivered to the final mbox mailboxes by a custom filtering script writtin in Python. Will dovecot happily serve mail from the existing hierarchy (obviously if I configure it right) so that I can connect using IMAP to my server machine to read mail? The mbox files are all under ~/Mail with several levels of directories in some trees. Does dovecot need any sort of … [View More]

sdbox and IMAP folders
by Jeff Larsen 08 Dec '14

08 Dec '14

We have just migrated from cyrus-imap to dovecot 2.2.9 on Ubuntu. By default, all our user's manually created folders appear at the same folder level as INBOX (i.e., they are next to INBOX, and not inside INBOX in a typical tree view of the folders). But on Dovecot, users are able to create new folders either parallel to INBOX or as subfolders within INBOX, which I think is going to lead to confusion for our users, especially when working from the limited UI of a smartphone client where folder … [View More]hierarchy is not as easy to visualize. With cyrus, this behavior depended on the client setting for "IMAP server directory" as it is called in Thunderbird. If the setting was given the value "INBOX", then all folders were parallel to INBOX and you could not create any folder that would appear in the tree inside INBOX. With the setting empty, then all folders appeared as subfolders of INBOX. It was all or nothing. When the mail accounts were migrated to dovecot, the existing top-level user folders were created in dovecot at the same level as INBOX. We did nothing intentional to get this result. We just used cyrus2dovecot to export to maildir, then doveadm sync to convert to the final sdbox. With dovecot, when "IMAP server directory" is empty, we get the original folder tree with all folders parallel to inbox, but users are also able to create subfolders inside INBOX . We are using sdbox storage and the folder heirarchy as seen in the client tree (parallel folders and subfolders) is also reflected in the server's local file system. If we change the "IMAP server directory" setting on the client while using dovecot, then all the folders that were previously at the same level as INBOX become inaccessible, so that's not a viable option. So, my question is this: Can I replicate the cyrus behavior where INBOX subfolders are an all-or-nothing option? Or are we stuck with users (having questionable file management skills in the first place) getting lost between INBOX subfolders and top-level folders.

Missing metadata on Dovecot 2.2.14, on Kolab 3.3, Centos 6.6

08 Dec '14

Hello everyone, We were trying to provision a system with Dovecot instead of another working cyrus kolab system. I am stuck with a problem with the metadata, especially when it comes to the Special Folders in Kolab 3.3, like Calenders, Tasks, etc, as well as any user created Folders. Emails work perfectly, and all the types are correct. But for example, If I try to change the type of Calenders, or create a new folder from inside roundcube and set it to type "Calenders", it stays at the … [View More]default which is "mail". Therefore it causes problems, when sharing events, since they are displayed as "mail" type and not "event" type. We've tracked the problem down to the metadata not existing for special folders.

Basically I am looking at both variants: 1) MD5-CRYPT password scheme storage with CRAM-MD5 auth mechanism 2) SHA512-CRYPT password scheme storage with PLAIN auth mechanism In my opinion the option 2) should be safer although it is using PLAIN auth mechanism. Of course I would always use STARTTLS and not allow unencrypted connection. What is your opinion? Best, ML

If I get a reproducer, I'll see if I can get core dumps. The user involved had several procmail processes hung waiting for the lockfile on this mbox. Killing sendmail & dovecot, the procmails & restarting sendmail & dovecot is all that I did after the errors. It is possible that the last message delivered prior to the errors was truncated ("note the input-eof" in the trace), but this shouldn't result in a panic. I'd expect a warning, then the message truncated to whatever is there, and operations proceeding... Also, it appears that make install doesn't remove the doveadm zlib plugin, which it seems was obsoleted by http://www.dovecot.org/list/dovecot-cvs/2012-October/021796.html. This results in: doveadm log find doveadm(root): Error: Module is for different ABI version 2.1.12 (we have 2.2.ABIv15(2.2.15)): /usr/local/lib/dovecot/doveadm/lib10_doveadm_zlib_plugin.so Removing /usr/local/lib/dovecot/doveadm/lib10_doveadm_zlib_plugin.* fixes this.

how to start a replication master-master correctly
by Eduardo Casarero 28 Nov '14

28 Nov '14

Hi all, I currently have one dovecot 2.2.15 working and I would like to add a second master server. If I configure the second server and enable the dsync in both servers, the sync will copy everything from A to B ? I mean, B server won't remove messages in A as it doesn't have anything in its users mailbox? The second master server will be a cold server just for contingency. Thanks

Hi! I've recently migrated my IMAP mail setup from a server running an older Debian Squeeze with dovecot 1.2.15 to a new Debian Jessie system with dovecot 2.2.13. In the old setup, it used to be so that a mail moved from a folder to another one was marked as deleted in the originating folder (in dovecot 1.2.15). In the new setup, the mail just disappears from the originating folder (with dovecot 2.2.13). The mail arrives properly in the target folder, so that's fine. But I actually liked the … [View More]

2.2.15: SMTP submission server?
by Ron Leach 27 Nov '14

27 Nov '14

List, we're migrating to 2.2 from a 1.x version. There has been mention from time to time of a dovecot SMTP submission server. Last I saw was Timo suggesting this would be a 2.3 feature, but that there was already a 'basic' capability in 2.2 that, more or less, merely provided a secured/authorised SMTP submission. I haven't found anything about this in the wiki, but the feature is of interest to us. I would like to *not* have our MTA capable of being exploited as a relay (it isn't, … [View More]

2.2.15 Panic in mbox_sync_read_next_mail()
by Hans Morten Kind 27 Nov '14

27 Nov '14

It might not be a fault in dovecot, as the user is accessing the folder locally with alpine while also running imap-sessions. However it would have been nice with a more graceful action than panic? The panic is preceeded by Error: Next message unexpectedly corrupted in mbox file PATH Panic: file mbox-sync.c: line 152 (mbox_sync_read_next_mail): assertion failed: (sync_ctx->input->v_offset != mail_ctx->mail.from_offset || sync_ctx->input->eof) At #7 in the enclosed backtrace … [View More]the actual values are sync_ctx->input->v_offset = 564 mail_ctx->mail.from_offset = 564 sync_ctx->input->eof = 0 Some will recommend convertion to maildir, but with 25 years history, thousands of active users and dozens terrabytes of mboxes, we are not even considering it. hmk GNU gdb 6.8 Copyright (C) 2008 Free Software Foundation, Inc.

Pigeonhole, vacation being sent incorrectly
by Harry Mills 26 Nov '14

26 Nov '14

Hi, I have an issue with a vacation message in a sieve script. I can't see an error in the script itself. Pigeonhole version: 0.4.2-32 Dovecot Version: 2.2.10 The script was created by Ingo (part of the Horde suite), but I think the script is fine. The problem is that when a message is sent to the "everyone" group (and alias for every person in the organisation), vacation messages are being sent back which I believe is an error. The script is: ==========================================… [View More]===== # Sieve Filter # Generated by Ingo (http://www.horde.org/apps/ingo/) (11/11/14, 5:20:06 pm GMT) require ["vacation", "regex", "fileinto"]; # Vacation if allof ( not exists "list-help", not exists "list-unsubscribe", not exists "list-subscribe", not exists "list-owner", not exists "list-post", not exists "list-archive", not exists "list-id", not exists "Mailing-List", not header :comparator "i;ascii-casemap" :is "Precedence" ["list", "bulk", "junk"], not header :comparator "i;ascii-casemap" :matches "To" "Multiple recipients of*" ) { if header :regex "Received" "^.*(2014) (\$.*\$ )?..:..:..

I cannot see the address for "user2(a)example.com" in any of those fields, or indeed referenced anywhere in the email. Is this a bug, or am I misunderstanding something?
