[Dovecot] Vacation - out of office
by Richard Gliebe 11 Aug '10

11 Aug '10

Hi all, is it possible to install/activate a "out of office" messages for each user in dovecot? I've read about the Sieve scripts, but can't find a howto to install it on your dovecot 1.0.7 installation. http://wiki.dovecot.org/LDA/Sieve ... With v1.1 it's possible to include other Sieve scripts in your script ... I know, its an old release, so don't treat me like a dog ;-). Upgrade to the newest version will be done at the next maintenance windows. many thanks Richard

[Dovecot] Outlook 2003 Client
by Richard Gliebe 11 Aug '10

11 Aug '10

Hi all, my dovecot IMAP Server (1.0.7-7.el5) is now up and running ;-) Now I want that all clients have to save there sent messages in the IMAP folder on the server. no problem with the thunderbird clients. BUT, I can't configure the office 2003 clients to save there send messages to the imap folder. Some people told me, that outlook 2003 isn't able to do that. The send messages folder have to be a "local" folder and not a folder on the IMAP server. I can't believe. The only way on outlook 2003 is to create a messages filter .... very strange .... many thanks Richard

[Dovecot] dot-containing foldernames \HasNoChildren bug ?
by Samuel Kvasnica 11 Aug '10

11 Aug '10

Hello, we experience problems with dovecot configuration using the listescape plugin to allow dots in foldernames. In some mail clients, dot-containing folders won't show any subfolders. This seems to be related to the fact that the \HasNoChildren flag is set on such folders even if subfolders do exits. Here is an example from telnet session: * LIST (\HasNoChildren) "/" "my.test" * LIST (\HasNoChildren) "/" "my.test/aaa" * LIST (\HasNoChildren) "/" "my.test/folder.first" * LIST (\HasNoChildren) "/" "my.test/folder.first/sub.sub.folder" * LIST (\HasNoChildren) "/" "my.test/folder.second" when we rename my.test to my_test everything works as expected: * LIST (\HasChildren) "/" "my_test" * LIST (\HasNoChildren) "/" "my_test/aaa" * LIST (\HasNoChildren) "/" "my_test/folder.first" * LIST (\HasNoChildren) "/" "my_test/folder.first/sub.sub.folder" * LIST (\HasNoChildren) "/" "my_test/folder.second" Could somebody look into this issue or give us some more debugging hints ? We use dovecot 1.2.13 + maildir + acl+quota+listescape, the config is: # 1.2.13: /etc/dovecot/dovecot.conf # OS: Linux 2.6.31.13-18-xen x86_64 openSUSE 11.2 (x86_64) xfs base_dir: /var/run/dovecot/ log_path: /var/log/dovecot protocols: imap imaps managesieve ssl: no disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(managesieve): /usr/lib/dovecot/managesieve-login login_processes_count: 5 mail_privileged_group: vmail mail_uid: vmail mail_gid: vmail mail_location: maildir:/data/vmail/%u/Maildir mail_debug: yes mail_executable(default): /etc/dovecot/gmember.sh mail_executable(imap): /etc/dovecot/gmember.sh mail_executable(managesieve): /usr/lib/dovecot/managesieve mail_plugins(default): fts fts_squat acl imap_acl quota imap_quota listescape mail_plugins(imap): fts fts_squat acl imap_acl quota imap_quota listescape mail_plugins(managesieve): mail_plugin_dir(default): /usr/lib64/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib64/dovecot/modules/imap mail_plugin_dir(managesieve): /usr/lib64/dovecot/modules/managesieve namespace: type: private separator: / inbox: yes list: yes subscriptions: yes namespace: type: shared separator: / prefix: Shared/%%u/ location: maildir:/data/vmail/%%u/Maildir:INDEX=/data/vmail/%u/index/shared/%%u list: yes namespace: type: public separator: / prefix: Public/ location: maildir:/data/vmail/Public:CONTROL=/data/vmail/%u/index/public:INDEX=/data/vmail/%u/index/public list: yes lda: postmaster_address: postmaster(a)xxx.co.at hostname: imap mail_plugins: acl sieve quota listescape mail_plugin_dir: /usr/lib64/dovecot/modules/lda log_path: /var/log/dovecot-deliver-errors.log info_log_path: /var/log/dovecot-deliver.log auth_socket_path: /var/run/dovecot/auth-master auth default: mechanisms: plain login user: vmail master_user_separator: # passdb: driver: passwd-file args: /etc/dovecot/dovecot.deny deny: yes passdb: driver: passwd-file args: /etc/dovecot/passwd.masters master: yes passdb: driver: ldap args: /etc/dovecot/dovecot-ldap_pass.conf userdb: driver: ldap args: /etc/dovecot/dovecot-ldap_user.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: vmail plugin: quota: maildir quota_rule: *:storage=16G quota_rule2: Trash:storage=100M quota_rule3: Junk:ignore quota_warning: storage=85%% /etc/dovecot/quota_warning.sh 85 %u quota_warning2: storage=90%% /etc/dovecot/quota_warning.sh 90 %u quota_warning3: storage=95%% /etc/dovecot/quota_warning.sh 95 %u acl: vfile:/etc/dovecot/acls:cache_secs=300 acl_shared_dict: file:/var/lib/dovecot/shared-mailboxes.db sieve: /data/vmail/%u/.dovecot.sieve sieve_dir: /data/vmail/%u/sieve fts: squat fts_squat: partial=4 full=7

[Dovecot] Thunderbird namespace handling
by Thomas Hummel 10 Aug '10

10 Aug '10

Hello, I've noticed that Thunderbird (3.0.3) seems to wrongly "repeat" the namespace prefix when selecting the top level maildir of a namesapce. It doesn't occur if "list=yes" and TB has no clue about the namespace prefix. But it seems to happen only when TB is aware of the namespace prefix, either via the NAMESPACE command (so in "hidden=no" setups) or via hard setting it up in the "Account Settings". For instance, if location = maildir:/courriel/boites/test:CONTROL=/courriel/meta/test hidden = no list = yes Trying to select the mailbox which appears as "#test" in the UI gives 4 select "#test/#test" in rawlogs, giving for the user a "Mailbox doesn't exist" error, whereas, via telnet, I can : x select "#test" * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 2 EXISTS * 0 RECENT * OK [UIDVALIDITY 1271768576] UIDs valid * OK [UIDNEXT 3] Predicted next UID * OK [HIGHESTMODSEQ 3] Highest x OK [READ-WRITE] Select completed. The same happens with any combination of (hidden=, list=, "Allow Server to override [the namesapce] settings") where TB knows about the namespace. Any ideas ? Thanks. -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

The slapd log file is showing "deffering operation: too many executing". When i googled i have seen that if the client is not properly disconnecting the connection slapd will give this error. Can you please let me know whether it is a dovecot problem and if so why it is occuring. -- Rgds, Aravind M D aravind.divakaran(a)yukthi.com Helpdesk Team Yukthi Systems Pvt Ltd Ph:- 08042351119 08042351120

[Dovecot] Why p_strdup and other string functions uses loops instead strlen? (dovecot 2.0.rc4)
by Len7hir 10 Aug '10

10 Aug '10

I did Dovecot profiling on huge e-mail system, and p_strdup was very high on list. I do minor change: p_strdup: /* for (len = 0; (str)[len] != '\0'; ) len++; len++; */ len = strlen(str) + 1; p_strndup: /* len = 0; while (len < max_chars && ((const char *) str)[len] != '\0') len++; */ len = strnlen(str, max_chars); And after changes strdup drop down on the profile list. This is output from oprofile: samples % symbol name 28000 10.9764 p_strdup 8507 3.3349 safe_memset 7857 3.0801 .plt 7627 2.9899 buffer_write 6871 2.6935 parse_body_add_block And after (about four times smaller samples, but shows everything): samples % symbol name 9595 26.2625 parse_next_body_to_boundary 8247 22.5729 parse_body_add_block 772 2.1130 .plt 672 1.8393 buffer_write 658 1.8010 __i686.get_pc_thunk.bx 614 1.6806 safe_memset 586 1.6039 pool_alloconly_malloc 559 1.5300 p_strdup 533 1.4589 hash_table_insert_node I wonder why You use loops instead strlen, which is optimalised on every platforms.

[Dovecot] maildirsize having incorrect content, how to recreate/correct?
by Thomas von Eyben 10 Aug '10

10 Aug '10

Hi List, I have (otherwise successfull) migrated a server from cyrus to dovecot (Mac OS X Server 10.5.8 to 10.6.4 [dovecotd version to be 1.1.20apple0.5]). There are ca. 300+ users of which a very small handfull (ca. 1 %) are having reported a usage size that is very different to what 'du' reports. How can I rebuild the maildirsize and why might it be wrong in the first place(?) Will the maildirsize files be regenerated if deleted and when will this then happen ( at the next time of the user logging in or…) >From what I can read here: http://www.inter7.com/courierimap/README.maildirquota.html The maildirsize file contains (in linenumber > 1) "bytecount SPACE filecount" I also have one (perhaps more) user with one line having a negative value in maildirsize (-138204393 -2294) how can that happen / be corrected?

[Dovecot] Dovecot 2.0.rc4 not generating ssl-parameters.dat on first start
by Andreas M. Kirchwitz 09 Aug '10

09 Aug '10

Dear Dovecot lovers! When starting Dovecot 1.x the first time, it runs "ssl-build-params" to generate a file named "ssl-parameters.dat". This takes a couple of minutes. During this time users have no access to their mail, but this can be planned in advance and users can be notified. This is explained in http://wiki.dovecot.org/SSL/DovecotConfiguration With Dovecot 2.0.rc4, the new command "ssl-params" seems to do this job, but unfortunately it isn't run on first start of Dovecot but the start is delayed until a user connects to port 993 (or does STARTTLS in 143). According to http://wiki2.dovecot.org/SSL/DovecotConfiguration it should behave the same way as Dovecot 1 did. So, with Dovecot 2.0.rc4 it hits the first user who wants to establish a secure connection. It's hard to explain this to users. ;-) Of course, I could simply run "telnet <imaphost> 993" manually after installation. I also tried running "ssl-params" manually before starting Dovecot but it stays in foreground forever and doesn't seem to finish (what is it waiting for?) So it would be really great if Dovecot 2 could do this on its own like Dovecot 1 did. Besides that, Dovecot 2.0 runs like a charm ... Andreas

[Dovecot] IMAP namespace and Courier migration
by Yves Goergen 09 Aug '10

09 Aug '10

Hello, the migration guide from Courier-IMAP to Dovecot says that I should change the folders namespace to "INBOX." if I want a seamless migration. Isn't it that e-mail clients determine that namespace automatically? At least I never needed to enter one in Thunderbird and then it was there. What happens if I copy the database, all the Maildir files, run the migration script to convert the special files and don't change that namespace - will clients show an error message and stop working or will it still work? -- Yves Goergen "LonelyPixel" <nospam.list(a)unclassified.de> Visit my web laboratory at http://beta.unclassified.de

[Dovecot] Dovecot 2.0.rc4 core dumped with Alpine 2.00
by Andreas M. Kirchwitz 09 Aug '10

09 Aug '10

Hi Timo and all others! The current Dovecot 2.0.rc4 did really well with Mutt 1.5.20 and Thunderbird 3.1.2, but a user with Alpine 2.00 crashed it immediately. I'm running Fedora 13 (Linux) and compiled Dovecot 2.0.rc4 manually like I did before with Dovecot 1.2.13. When switching from 1.2 to 2.0 I removed all those ".imap" folders with internal cache data (didn't know for sure if it's compatible between both version). All folders are in mbox format. When Alpine is started, the first crash happens. Alpine notifies the user that there was a problem connecting the IMAP server. No mail is display. And then the second crash happens. Looks like Alpine starts a second try to connect to the IMAP server before displaying the (empty) screen with (no) folders.

[Dovecot] Dovecot and Active Directory separate domain data stores.
by Andrew Bruce 09 Aug '10

09 Aug '10

Hi, I've got Dovecot setup to auth my AD users fine via Winbind and I've also tried it using LDAP and can get this working also. The problem lies in the way we store our email for our virtual users in this setup. We run a flat domain for AD (lets call it newzealand.local), and then under each users account that gets email, in the E-mail field in AD, they have an email address like user1@auckland, user2@wellington, user3@chch and so on. With Postfix, I've set it up so that each email domain ends up being stored in a different path - /mail/auckland/user1, /mail/wellington/user2, /mail/chch/user3. This was done using a query filter that returned a person's email address from AD, chopped it into separate user/domain parts around the '@' symbol and using these to determine where the mail should be stored. This seems to work well for our purposes. But now I need to get Dovecot to be able to do the same thing in order to present the email to the user. I'm fairly certain this isn't going to work with Winbind, so I implemented the LDAP passdb and got that working, but I can't seem to quite work out how to get it to work with the domain part from the email address. Could someone give me a pointer in the right direction if this is possible. I'm thinking it has to do with the user_attrs variable, but can't quite workout how I would split this. Or is there a better way to do this? Thanks, Andrew

[Dovecot] Setting up webmail in DMZ
by Phill Edwards 09 Aug '10

09 Aug '10

I have a Smoothwall server on my network and am running three network interfaces off it. 1) local LAN 192.168.0.0 with PCs and an internal dovecot server on 192.168.0.154. 2) internet interface 3) DMZ 192.168.2.0 which has a linux web server 192.168.2.1 on which I want to install a webmail so I can access my email remotely. Originally 192.168.2.1 couldn't see the 192.168.0.0 network but with some help from the Smoothwall forums I have fixed that. The problem now is that 192.168.2.1 can't connect to the dovecot server on 192.168.0.154. When I "telnet 192.168.0.154 993" or "telnet 192.168.0.154 143" I get a "Connection refused" error. But these commands work fine from PCs on the 192.168.0.0 network. I'm pretty sure there's no firewall on the dovecot server and /etc/hosts.allow and /etc/hosts.deny are empty. Is there a default setting that I need to change in Dovecot that only allows connections from machines on the same subnet?

[Dovecot] Searching dovecot Maildir

Hi All, Loving Dovecot after several years with Cyrus. This might be more a general question, but this seemed the best place to ask. The idea is to just add up all the values of quotes I've sent in a month. I want to search my Sent mail folder for all messages with a certain subject, then "grep" out a certain line that has a dollar ($) figure, and add up those figures. The idea is to just add up all the values of quotes I've sent in a month. Can it be done? Any help appreciated. regards, Murray Dovecot 1.2.6
