[Dovecot] sieve-filter ignoring separator
by Isak Rubin 03 Apr '13

03 Apr '13

It seems like running sieve-filter from the console ignores the separator setting, thus not letting me filter into folder names containing dots. Normal delivery using lda handles it just fine, but not when using the sieve-filter command. Character not allowed in mailbox name: '.' Is there anyway to override this or is patching and recompiling the source my only option? # dovecot --version 2.1.9 /Isak

[Dovecot] Sieve vacation issue - Dovecot + Postfix + LDA
by Ivan Bogdanovic 03 Apr '13

03 Apr '13

Hi to all, I have an issue with Dovecot Sieve on sending vacation message... Actually Sieve is working and I can use all the filters but just vacation is causing a problem and only in specific case... I have Dovecot + Postfix + LDA running on Ubuntu 11 without MySql database for users but I'm using virtusertable instead. The problem is when linux user ( mail user ) is different from mail allias in virtusertable... Example: ivan(a)domain.com > ivan1 ( from virtusertable ). When alias and user are the same sieve vacation works just fine but when it's not the sieve script collects the user(ivan1)(a)domain.com in from instead ivan(a)domain.com and this is when mail log shows like "discarded message because of implicitily no known envelope in message header etc... Is there a way to adjust sieve to pickup the recipient address from mail header or whatever and not to collect the user...? I was trying to play with postfix master.cf using dovecot-lda switches -f ${sender} -a (or -d ) ${recipient} but without success... Did anyone had this kind of problem? I would really appreciate some hints on fixing this issue... Thanks, Ivan

[Dovecot] Separate log file for Sieve
by Ewald Dieterich 03 Apr '13

03 Apr '13

I use log_path = /var/log/dovecot/error.log info_log_path = /var/log/dovecot/info.log debug_log_path = /var/log/dovecot/debug.log to log to different files. Since I don't consider Sieve errors as severe as "real" Dovecot errors I would like to keep them away from the error log. Is it possible to configure a separate log file for Sieve?

[Dovecot] (no subject)
by Walter Steiner 02 Apr '13

I've run into a problem with `doveadm backup` (2.2 rc2 and 20130226) I did not notice in 2.1.15 doveadm backup [-Dv] -R -u cyrtest1(a)iai.uni-bonn.de -m INBOX imapc: => crashes (signal 6 with acl plugin configured, sig 11 without acl) If this is considered a bug (not just because of the crash but in the meaning of "my configuration should work") it would be great if it could be fixed.;-) If I can provide more detail (log, gdb bt full and doveconf -n follow the next paragraph) or test something I would be happy to to so. As I'm planning dsync replication of the two backends I thought it would be better to start things with the upcoming new dovecot 2.2 (dsync protocol) instead of 2.1.15. (?!) --- first some information about what I'm trying to do --- We want to replace our single cyrus 2.4 server with two backend servers (separate storage and all user mailboxes etc. each) Even if cyrus-to-cyrus should be much easier _and_ time is slipping away I want to take this one opportunity to switch to dovecot if possible. - Thank you very much for your great work on dovecot and all the efforts! - We want the IMAP clients to continue using their folders/messages etc so I want to reproduce the "cyrus structure" we are using for the last 14 years: - own user folders: INBOX and INBOX.subfolder ... - (if possible: other user folders: user.otheruser...) - converting as much as possible of existing data To get the folders/messages into the new dovecot server(s) I'm thinking about some repeated "doveadm mirror / backup -R ... imapc:" runs while the cyrus server is still in use. The first sync run will take several days but a few more and the time will be short enough to do the complete switch-over w/o surprises. Insertion: I played with 2.1.15 and namespaces but maybe I did not understand this well enough: doveadm backup -R -u userx [w or w/o -m INBOX and/or -n INBOX] imapc: => if cyrus userx has permissions on other users mailboxes these folders are also copied. ... copied _into_ the INBOX of (dovecot) userx. I too got the known problems with INBOX.INBOX. paths. I changed dsync-brain.c sources to skip "^user." folders and to cut the additional "INBOX." => seems okay... messages (only the expected) got transferred! --- To see if things still work as with 2.1.15 (no dsync source modification!) I did (as before with 2.1.15): doveadm backup [-Dv] -R -u cyrtest1(a)iai.uni-bonn.de -m INBOX imapc: => but it crashes (signal 6) doveadm(cyrtest1(a)iai.uni-bonn.de): Debug: auth input:

[Dovecot] Dovecot 2.2rc3 Client Cert Auth and Webmail -> auth_ssl_require_client_cert problem
by Christian Felsing 31 Mar '13

31 Mar '13

Hello, I would like to set up a Dovecot based mail system which uses X.509 Client Certificates for authentication. A webmail system based on Horde5 should use Dovecot as backend. For now Dovecot works with client certificates issued by my CA and Horde authenticates also with same client certs. Due to protocol it is impossible to use client certs presented by user to Horde for authentication at Dovecot, so Horde should be allowed to authenticate itself without or an arbitrary password to Dovecot. Horde and Dovecot are running in same protected LAN. Unfortunately Dovecot does not support different authentication methods on different IP addresses or ports. This does not work: remote 192.168.116.28/32 { auth_ssl_require_client_cert = no auth_ssl_username_from_cert = yes disable_plaintext_auth = no ssl = yes } Result is "doveconf: Fatal: Error in configuration file /opt/dovecot-2.2.rc3/etc/dovecot/conf.d/10-auth.conf line 103: Auth settings not supported inside local/remote blocks: auth_ssl_require_client_cert" Replacing "auth_ssl_require_client_cert = no" by "ssl_verify_client_cert = no" does not yield in an error, but it does nothing, Dovecot still insists for a client certificate. I afraid that I am trapped by this problem: http://dovecot.2317879.n4.nabble.com/Problem-with-requiring-client-certific… Is there any way to turn off client certs for specific local or remote IP addresses? best regards Christian

[Dovecot] Incorrect response when opening read-only mailboxes with per-user flags?
by Guido Berhoerster 31 Mar '13

31 Mar '13

After some debugging on the protocol level I've finally found the problem with per-user seen flags in read-only mailboxes. Dovecot actually does allow storing the seen flag on messages but AFAICS it does not communicate that correctly to clients, this is what its response to selecting a read-only mailbox with "lrs" ACL in effect for the logged in user looks like: 2 SELECT "Public/Test" * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS ()] Read-only mailbox. * 2 EXISTS * 0 RECENT * OK [UNSEEN 2] First unseen. * OK [UIDVALIDITY 1364221612] UIDs valid * OK [UIDNEXT 3] Predicted next UID * OK [HIGHESTMODSEQ 1] Highest 2 OK [READ-ONLY] Select completed. Shouldn't PERMANENTFLAGS contain \Seen here if per-user seen flags are enable and should it even be tagged READ-ONLY at all in this case? At least clients such as Python imaplib, IMAPClient, or Roundcube will open such mailboxes with EXAMINE and thus do not allow the modification of flags. -- Guido Berhoerster

[Dovecot] dsync mirror to convert from mbox (1.2x) to mdbox (2.2)
by Ken A 31 Mar '13

31 Mar '13

I'm converting mail from mbox to mdbox. I've copied mail over to a new system, and now I'm running dsync like this: dsync -u username mirror mbox:/folder_location/username:INBOX=/inbox_location/username That seemed to work, with a couple minor errors: > dsync(username): Warning: Our dotlock file /mail_location/username.lock was deleted (locked 20 secs ago, touched 20 secs ago) > dsync(username): Error: file_dotlock_delete() failed with mbox file /mail_location/username: No such file or directory Do I also need to specify where dovecot's indexes are for the old mbox files, or is this not needed for mbox conversions (when they are the source)? Thanks, Ken A.

[Dovecot] Dovecot METADATA support
by Bruce Marriner 31 Mar '13

31 Mar '13

I've been trying to work with dovecot metadata plugin and posted a question here related to that a few days ago here : http://www.dovecot.org/list/dovecot/2013-March/089241.html I just read today (e-mail on this list) from Timo Sirainen that >> >> Dovecot is getting close to having native METADATA support. >> I am very curious about this. When is "getting close" and I would guess this will be for v2.2? Will this support be the same as the dovecot-metadata-plugin in hg or something completely different? I'm sorry if I'm asking questions that have already been answered. My goal is to use Kolab3 with Dovecot instead of using Cyrus IMAP and Kolab requires metadata/annotation support. Right now I'm testing this using the dovecot-metadata-plugin but I am very interested it learning about native metadata support and testing it with Kolab 3. Any detail you can provide would be very appreciated. Bruce

[Dovecot] Custom Headers/Flags Support in dovecot
by Ramesh Natarajan 31 Mar '13

31 Mar '13

I am currently trying to evaluate if I can use dovecot to be used for my imap server like application. This is not an email application but a generic storage server that uses IMAP protocol to save and retrieve messages. The messages have standard From/To/Date headers and a lot of custom headers for threading conversations e.t.c. As a part of my application requirements I also need to support custom flags and have ability to set/change/retrieve them via IMAP. 1) Does Dovecot support custom flags to be set/changed/retrieved? 2) I understand dovecot optimizes standard RFC822 headers and flags in cache/index files for faster lookups and searches. Does custom headers and flags fall into this optimization algorithm? 3) I am planning to support multiple users and each mailbox may have upto 1000 folders. Each folder may have an average of 20 MIME encoded messages. I am planning to use local storage with single-dbox format. Do you see any issues with this? thanks Ramesh

[Dovecot] Conversion from Evolution maildir to imap
by Paul van der Vlis 31 Mar '13

31 Mar '13

Hello, A customer has a thin-client server with 100+ homedirs with Evolution. They are using POP3 and maildir. Now I want to switch to IMAP. Can I use Dovecot on this maildirs, or does Evolution use another kind of maildir? Does Dovecot change anything in the maildirs? Do I loose my flags this way, like "read" ? Normally I am using Cyrus IMAP. What I want to do is to install Dovecot to have access to the mail over IMAP because Dovecot can do maildir (Cyrus cannot). Then I can use imapsync to sync everything to Cyrus. Do you think that's a good idea? With regards, Paul van der Vlis. -- Paul van der Vlis Linux systeembeheer, Groningen http://www.vandervlis.nl/

[Dovecot] Managesieve Automatic Homedir Creation: File not Found Error
by linuxer＠netsteps.ch 31 Mar '13

31 Mar '13

Hi all, I'm running dovecot version 2.0.19 (Ubuntu 12.04) and I discovered some unexpected behaviour related to the Dovecot managesieve module. When connecting to the managesieve service from a client for the first time (e.g. roundcube webmail), I get an application error. This is logged by Dovecot: Error: sieve-storage: opendir(/var/.../exampledomain/exampleuser@exampledomain//sieve) failed: No such file or directory. At first glance I thought the problem was caused by the "//" in the directory path. I assume this is just a concatenation of the user virtual home directory (in my case "/var/.../exampledomain/exampleuser@exampledomain/" and the default sieve folder (~/sieve). While this looks wrong it seems not to be the actual problem (should be fixed though?) Then I noticed that the user home directory and sieve data were actually properly created despite the error. When connecting again, it worked without error. The problem can be reproduced by deleting the users virtual home directory and connecting again. A guess would be that the automatic creation of the virtual users homedir folder structure is some asychronous process not being completed in time. I also found this older thread with a similar issue: http://osdir.com/ml/dovecot-development/2010-05/msg00018.html Could also be worth mentioning that I'm running Dovecot on a virtualized host with possibly relatively poor I/O performance (maybe faster environments don't have this problem). Thanks for looking into this, and thx for the really neat dovecot software package! Cheers, L.

[Dovecot] ACL for root-level mailboxes
by Bradley Rintoul 31 Mar '13

31 Mar '13

Hello: I see in the documentation where it says that if mailboxes are created at the root level it will use the namespace's default ACL. I'm using Dovecot 2.0.9 so there is no default namespace defined, so I'm a bit handicapped here... Anyway, assuming I can figure out how to define a default namespace, how do I specify its ACL? Where would the file describing the access go? Sorry if this is a bit broad, but any help would be appreciated. Thanks, B. Rintoul

[Dovecot] 3 node setup without cluster filesystem
by Michael 30 Mar '13

30 Mar '13

Hi everyone, short version: Is there any 3 host (two MX and one frontend IMAP) that can use a shared (iSCSI) ext4 volume? Long version: I am running a very complex setup right now with two MX, two proxies(lmtp/imap)/imap-frontends and two backends mounting an ocfs2 volume. I would like to reduce the complexity (and the number of hosts) and get rid of ocfs2. I ask myself if I can use an ext4 iSCSI-LUN using this setup: MX01 -> lmtp:unix:private/dovecot-lmtp -> mail_home: /var/mail MX02 -> lmtp:unix:private/dovecot-lmtp -> mail_home: /var/mail IMAP01 (imap) -> mail_home: /var/mail Regards Michael

Greetings, Can anyone give me a quick pointer to the right command to use for restoring backups made by dsync? I have our whole mail server backed up with it, but not sure how to restore... Any help would be greatly appreciated. -- --Asai

Hello, (2.2:) there is no doveadm subcommand to change flags of messages, is it? The following should work reliably? # mark messages with subject $SUBJECT in mailbox $MAILBOX of user $USERID as read ( i=2 echo "1 SELECT "$MAILBOX doveadm search -u $USERID mailbox $MAILBOX subject "$SUBJECT" \ | while read g u do echo $i" UID STORE "$u" flags (\Seen)" i=$((i+1)); done echo "0 LOGOUT" ) | /usr/lib/dovecot/imap -u $USERID Greetings, Lutz
