Migrating to Dovecot EE
by Philipp Resch 10 Oct '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello everyone! I am currently running dovecot 2.2.9 on my Debian Wheezy system. As this version is a bit outdated and I'm not too keen on compiling Dovecot myself I was thinking about moving to the Dovecot EE repository. I already have access to the repository, and now before I starting "apt-getting" all kinds of packages: What would be the best way on moving to the Dovecot EE repository? Just doing an apt-get install dovecot-ee? Will it replace the current version? Or should the old version be removed before installing the new one? Has anyone ever done this and has some advice for me? Thanks in advance, Philipp -----BEGIN PGP SIGNATURE----- iQEcBAEBAgAGBQJUN50yAAoJEC6sCbYfpzg9ilcH/iREEyhyygKEVrCyLRjutcLm iLa63KHCFGFjU3b5igZFD+Jv1uZmHfyLh+ZFz0ditHmS1jbNE49WKGawAuoBb3lv VqMCex3qsOA9OVdAbPYUCecs7K18Oo8DjwFpI4Sn70flsaFpo3JS32I/dZ9OMF7d p9O/G1PfJ4mw4zWC0HGgE7kluYytPBJTw2rqqAyjHXypQhcpiF+HHtFm/pX9SF4U b4K5YqfFJE/Bk7YYEdnQFyribcDxkllIzeAt09EhpEwZHK8MTWi92PwnHDcTX3M4 P7JnmSO3YtfSphbqDOFZgAYz2otEAPgysXu3v4asLkcoiPQb/H7hUlcNZyzLeIo= =fu6j -----END PGP SIGNATURE-----

question: dovecot lda running as special user (vmail) or normal user (marcel)?
by marcel.cochem 10 Oct '14

10 Oct '14

Dear Mailing List, (version and dovecot -n at the bottom) (Sorry for the bad English in this mail :) ) I'm new to dovecot and wanted to build my own mailserver using dovecot+postfix. I currently have a Problem with Permissions with my mailfolder. I could solve it easily if i set it with chmod to 777. but thats no real solution. While reading my log files i see a lot messages like: Oct 10 05:19:52 lda(owncloud): Error: user owncloud: Initialization failed: Initializing mail storage from mail_location setting failed: stat(/home/vmail/example.com/owncloud/mail) failed: Permission denied (euid=100(owncloud) egid=1004(owncloud) missing +x perm: /home/vmail, dir owned by 5000:5000 mode=0700) Oct 10 05:19:52 lda(owncloud): Fatal: Invalid user settings. Refer to server log for more information. So Currently two Users need to acces the mail-folder: 1. The user itself (here: owncloud) 2. The vmail user I want to use dovecot with virtual users. Now the question is: shouldn't the directory be accessed only by the vmail user? and not by the owncloud user? Second Quest: If it's correct that the access is made by 2 users: what rights do they need? I Cant add all users to the group vmail and set g+rwx Permissions (every user could read mails from other users, and even edit them!) Thanks a Lot.

Keywords & sync
by Ralf Hildebrandt 10 Oct '14

10 Oct '14

We're using keywords within Thunderbird, and we're syncing those using IMAP. When using more than 5 keywords, we're envcountering problems - they're only partially being synced (between two clients, but not all clients). Any idea why this could be happening? The introduction of tagging in Thunderbird is described here: <https://bugzilla.mozilla.org/show_bug.cgi?id=114656> -- [*] sys4 AG http://sys4.de, +49 (89) 30 90 46 64 Franziskanerstraße 15, 81669 München Sitz der Gesellschaft: München, Amtsgericht München: HRB 199263 Vorstand: Patrick Ben Koetter, Marc Schiffbauer Aufsichtsratsvorsitzender: Florian Kirstein

Send an alert on master user login
by Andre Rodier 09 Oct '14

09 Oct '14

Hello, I want to know if there is an option in Dovecot to send an alert, or run a script when someone is using the master user facility. I can do something myself with fail2ban, but maybe there is an option in Dovecot? Thanks. André.

Sieve filter extracting wrong header value on certain mail messages
by gowen (dovecot) 09 Oct '14

09 Oct '14

# 2.2.12: /etc/dovecot/dovecot.conf # OS: Linux 3.15.4-x86_64-linode45 x86_64 openSUSE 12.3 (x86_64) Short version: 1) I filter out spam by using a dovecot sieve filter to act based on a header inserted by bogofilter 2) In some cases, sieve fails to correctly file based on this header 3) Testing with sieve-test indicates that it's testing the wrong header 4) Suggestions? Am I doing something wrong? Is there a problem with these headers that bends test-sieve out of shape? 5) Test files from below are also available via http://www.swynwyr.com/sieve-test/ Any help is appreciated!!! Long version with full details: Here is the simple sieve filter I'm using to test, and two different variants of an email which triggers this problem. I basically deleted things one by one from an original email (1) to get minimal testcases that triggered (2) or did not trigger (3) the problem. The filter: === begin test.sieve === require ["fileinto", "body", "regex"]; if header :contains "X-Bogosity" "Spam," { fileinto "SPAM.SPAM"; stop; } elsif header :contains "X-Bogosity" "Unsure," { fileinto "SPAM.UNSURE"; stop; } keep; stop; === end test.sieve === Here is an example email that will cause this filter to not function as expected: === begin message.2 === Return-Path: <alora(a)promosforusio.org> Subject: =?utf-8?B?QUhTIEtpdGNoZW4gTWFrZW92ZXIgR2l2ZWF3YXkg?= Subject: ÎHS KitÑhen ÎakÐµovÐµr GivÐµaway Subject: =?ISO-8859-1?Q?AHS Kitchen Makeover Giveaway =A0=A0=A0?= Subject: Subject: AHS Kitchen Makeover Giveaway X-Bogosity: Spam, tests=bogofilter, spamicity=1.000000, version=1.2.3 Home Warranty Summer Giveaway === end message.2 === If I run test-sieve on this, we can clearly see in the trace log that when it's supposed to test for header "X-Bogosity" it in fact looks at one of the multiple "Subject" headers. Note that the result is storing in INBOX rather than SPAM.SPAM, and that the "matching value" for "X-Bogosity headers" is actually the contents of the final "Subject" header in the test on line 3. In the second test, on line 6, it uses a different and correct value for the same header! But too late to help as the first test was the one it should have had a match on. === begin session === $ sieve-test -t trace2.log -Tlevel=matching test.sieve message.2 Performed actions: * store message in folder: INBOX Implicit keep: (none) sieve-test(gowen): Info: final result: success $ cat trace2.log ## Started executing script 'test' 3: header test 3: starting `:contains' match with `i;ascii-casemap' comparator: 3: extracting `X-Bogosity' headers from message 3: matching value `AHS Kitchen Makeover Giveaway' 3: with key `Spam,' => 0 3: finishing match with result: not matched 3: jump if result is false 3: jumping to line 6 6: header test 6: starting `:contains' match with `i;ascii-casemap' comparator: 6: extracting `X-Bogosity' headers from message 6: matching value `Spam, tests=bogofilter, spamicity=1.000000, version=1.2.3' 6: with key `Unsure,' => 0 6: finishing match with result: not matched 6: jump if result is false 6: jumping to line 11 11: keep action; store message in default mailbox 12: stop command; end all script execution ## Finished executing script 'test' $ === end session === Now lets remove the "Return-Path" from that message. (Of the original 26 headers, all but the 7 shown in message.2 could be removed and still have this message break the filter). This alters thing enough that sieve starts working as expected (in fact, removing any one of the 6 non-X-Bogosity headers will cause this to start working). === begin message.3 === Subject: =?utf-8?B?QUhTIEtpdGNoZW4gTWFrZW92ZXIgR2l2ZWF3YXkg?= Subject: ÎHS KitÑhen ÎakÐµovÐµr GivÐµaway Subject: =?ISO-8859-1?Q?AHS Kitchen Makeover Giveaway =A0=A0=A0?= Subject: Subject: AHS Kitchen Makeover Giveaway X-Bogosity: Spam, tests=bogofilter, spamicity=1.000000, version=1.2.3 Home Warranty Summer Giveaway === end message.3 === Now when we run test-sieve it works as expected, filing into SPAM.SPAM and showing the correct matching value for line 3: === begin session === $ sieve-test -t trace3.log -Tlevel=matching test.sieve message.3 Performed actions: * store message in folder: SPAM.SPAM Implicit keep: (none) sieve-test(gowen): Info: final result: success $ cat trace3.log ## Started executing script 'test' 3: header test 3: starting `:contains' match with `i;ascii-casemap' comparator: 3: extracting `X-Bogosity' headers from message 3: matching value `Spam, tests=bogofilter, spamicity=1.000000, version=1.2.3' 3: with key `Spam,' => 1 3: finishing match with result: matched 3: jump if result is false 3: not jumping 4: fileinto action 4: store message in mailbox `SPAM.SPAM' 5: stop command; end all script execution ## Finished executing script 'test' $ === end session ===

mailbox in different filesystem
by Héctor Moreno Blanco 08 Oct '14

Hello everyone, We have Dovecot 2.1.6 with Maildir. We would like to perform some kind of mail archiving with a mailbox in a different storage, for example a mailbox called ARCHIVED, with different disks (slower...). Is possible to locate this mailbox in other storage (SAS, Fiber...) and how can we do it? Thank you very much in advanced. Kind regards.

Sorry Gianluca, I know IMP/Horde just by name. Some googling show me that the option: $servers['advanced'] = array(...,'acl' => true,...) could help you, but you can get some issues: https://sys4.de/en/blog/2013/11/06/imap-acl-dovecot-horde-5-imp-6-warning/ On 10/07/2014 09:30 AM, Gianluca Calloni wrote: > HI Eduardo. > > > > Thank you for your replay.. > > > > You know if there is a plug-in also for Horde webmail GUI? > > > > Unfortunately we use outlook and it seems there is not addon for this.

HI Eduardo. Thank you for your replay.. You know if there is a plug-in also for Horde webmail GUI? Unfortunately we use outlook and it seems there is not addon for this.

dovecot 2.1 new imap folder permissions
by Stefanos Gerangelos 07 Oct '14

07 Oct '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I hope this is the appropriate place to ask. I am migrating an old mail (postfix/dovecot) server to a new one. Everything works much as expected. I have a small obstacle though. I use mbox format and the setup is pretty much simple. Suppose a user's home directory is the following: # ls -ld /home/foo drwxr-xr-x 3 foo users 4096 Oct 4 13:28 foo and the respective /var/mail: # ls -ld /var/mail/foo - -rw------- 1 foo mail 0 Oct 4 23:45 /var/mail/foo In the old server when the user tried to create a new test imap folder (from an imap client), then the newly created file would be: # ls -l /home/foo/ - -rw------- 1 foo users 0 Oct 2 02:08 test This is the desired behavior. In the new dovecot 2.1 server the following file permissions will apply: # ls -l /home/foo/ - -rw-r--r-- 1 foo users 0 Oct 2 02:08 test I finally noticed that if I chmod the /home/foo to 711, then the new file will have the desired (600) permissions. So, I can make a umask for the new users (login.defs), but that doesn't sound a pretty solution. Do you have anything else to suggest? If you need any .conf file, let me know.

Hi Gianluca, I have roundcubemail as webmail. It has a plugin called 'acl', that allows users create acls easly. My users use to use thunderbird too, and the solution is that add-on: https://addons.mozilla.org/en-US/thunderbird/addon/imap-acl-extension/ On 10/06/2014 09:49 AM, Gianluca Calloni wrote: > Hi dovecot guru.. > > > > I need some help configuring shared folder in my server.. > > This is the situation: > > DOVECOT 2.0.19 > > with POSTFIX - CLAMAV - AMAVISD - SPAMASSASSIN > > > > This is the production server and sharing folder between user work.. > > But i need some explanation.. > > > > 1) It's possible to share only a subfolder (E.G. => .INBOX.ESTERO) without > share the main folder .INBOX? > > 2) Which is the best way (or best practice) to manage the dovecot-acl and > dovecot-acl-list file??
