by jean-Noël Chardron 24 Jun '09

24 Jun '09

Hello, Some users subscribe to several mailing lists which causes them to have the same message several times what they do not want . Today we use procmail as delivery agent to discard duplicate message, we want to migrate to dovecot deliver + sieve I read a previous post about the duplicate messages : http://www.dovecot.org/list/dovecot/2007-March/021085.html But I do not understand if this feature exists and how to activate Some explanations or documentation would be welcome. thank you, -- Jean-Noel Chardron

[Dovecot] dovecot-antispam problem with sa-learn
by maxlosblob＠tiscali.it 24 Jun '09

24 Jun '09

Hi all, I just set up a dovecot+postfix+roundcubemail+spamassassin system with virtual users. These applications work fine, I have a problem with the dovecot-antispam plugin. Dovecot is compiled from tarball, version 1.1.16, the plugin is version 1.2. The problem is that when I move messages from or to "Posta indesiderata", which is in antispam_spam list, nothing happens. I have no logs about sa-learn activity in /var/log/maillog, nor in /var/log messages, no matter if I set DEBUG=syslog or DEBUG=stderr. Here are my confs: dovecot-antispam .config BACKEND=mailtrain USER=root GROUP=root DEBUG=syslog DEBUG_VERBOSE=5 PLUGINNAME=antispam dovecot -n # 1.1.16: /usr/local/etc/dovecot.conf # OS: Linux 2.6.18-sblob i686 CentOS release 5.2 (Final) simfs protocols: imap pop3 ssl_disable: yes disable_plaintext_auth: no login_dir: /usr/local/var/run/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login last_valid_uid: 500 first_valid_gid: 500 last_valid_gid: 500 mail_location: maildir:/var/virtual/%d/%n/Posta mail_debug: yes mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable (pop3): /usr/local/libexec/dovecot/pop3 mail_plugins(default): listescape antispam mail_plugins(imap): listescape antispam mail_plugins (pop3): mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir (pop3): /usr/local/lib/dovecot/pop3 namespace: type: private separator: / inbox: yes list: yes subscriptions: yes auth default: passdb: driver: sql args: /etc/dovecot-sql.conf userdb: driver: static args: uid=500 gid=500 home=/var/virtual/% d/%u plugin: antispam_trash: trash;Trash;Deleted Items;Cestino; antispam_spam: Spam;Posta indesiderata;.Posta indesiderata;SPAM;.SPAM antispam_mail_sendmail: /usr/bin/sa-learn antispam_mail_spam: --spam antispam_mail_notspam: --ham antispam_mail_tmpdir: /tmp Thanks in advance Max Non rinunciare ai tuoi ricordi...Tiscali Photo affronta la crisi con incredibili offerte http://photo.tiscali.it

[Dovecot] v1.2.rc6 released
by Timo Sirainen 24 Jun '09

24 Jun '09

http://dovecot.org/releases/1.2/rc/dovecot-1.2.rc6.tar.gz http://dovecot.org/releases/1.2/rc/dovecot-1.2.rc6.tar.gz.sig I think it's time to get v1.2.0 released soon. There is apparently still one rare crashing bug in virtual plugin, but unless someone can reproduce the bug I'm not going to delay v1.2.0 because of it. The release plan is: - Release v1.2.rc7 next Friday (assuming there have been some fixes) - Release v1.2.0 the next Monday I'll be giving a Dovecot talk in Berlin on July 2nd, and I really want to have v1.2.0 released by them. So July 1st is the absolute final deadline for v1.2.0. :) Changes since rc5: * imap proxy: Pass through to client unexpected untagged replies from remote server (e.g. alerts). * Solr: Don't use "any" copyfield, it doubles the index size. * mail_location: Allow using ":" characters in dir names by escaping it as "::". - mbox: Don't crash with invalid From_-lines. - IMAP: Don't crash if IDLE command is pipelined after a long-running UID FETCH or UID SEARCH. - ACL / shared mailbox fixes - Some metadata files were incorrectly getting 0666 permissions.

[Dovecot] courier-imap 2 Dovecot Migration
by Odhiambo ワシントン 24 Jun '09

24 Jun '09

I have a question about migration from courier-imap. I have a server running courier-imap which I'd like to change to dovecot. The problem at hand is that there are POP3 users as well as IMAP4 users.Some of the POP3 users have the option to "leave a copy of the message on the server" set in their MuAs. Is it possible to migrate from courier-imap --> Dovecot and not have these people re fetching all their old e-mails all over again? -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254733744121/+254722743223 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ "If you have nothing good to say about someone, just shut up!." -- Lucky Dube

[Dovecot] tcp_wrappers
by listmail 23 Jun '09

23 Jun '09

Hi, I've just started using Dovecot (v1.1.14), and I'm noticing a lot of dictionary attacks. I searched through the documentation and the mailing list archives hoping to find support for tcp_wrappers (hosts.deny) support. I did find some suggested patches in the list from last year, but as far as I can tell, there is no support in the released versions. Is this implemented and undocumented, or just unimplemented? I would be surprised to find it unimplemented in such an otherwise sophisticated project. Thanks in advance, --Bill

[Dovecot] A X-Mailbox header?
by Alessandro Ranellucci 23 Jun '09

23 Jun '09

Hi all, I'm waiting for the virtual mailbox feature in order to make a single POP3 access to retrieve messages contained in all my mailbox folders. This is because I use webmail and other IMAP clients but my main workstation uses a POP3-only client. I was wondering if there's a way to keep the name of the folder containing each message while retrieving via POP3. I guess this could be done by dynamically adding a header to messages at retrieval time. Is there a feature for this or a plugin API? Otherwise I was thinking about modifying the messages themselves on the server using a script. However, such a script would need to be run when a IMAP user moves a message to a folder and I believe Dovecot doesn't provide a trigger/hook mechanism. I also don't know if modifying stored messages is allowed since it could break some caching/hashing mechanism. Do you have any idea for this? Thanks in advance and thanks to Timo for the great work! - alessandro.

Dear friends, My intention is to migrate from Courier-Imap Dovecot 4.4.1 to 1.1.16, the problem is that I've noticed that when creating folders using the Courier does not create the file courierimapsubscribed therefore I doubt if this will bring me problems trying to perform the migration script by courier-dovecot-migrate.pl drwx------ 8 vpopmail vchkpw 4096 Jun 18 16:38 . drwx------ 3 vpopmail vchkpw 4096 Jun 18 09:32 .. drwx------ 2 vpopmail vchkpw 4096 Jun 18 16:36 courierimapkeywords -rw-r--r-- 1 vpopmail vchkpw 265566 Jun 18 16:36 courierimapuiddb drwx------ 2 vpopmail vchkpw 593920 Jun 16 10:05 cur drwx------ 2 vpopmail vchkpw 4096 Jun 18 09:32 new drwx------ 6 vpopmail vchkpw 4096 Jun 18 16:38 .Personal drwx------ 6 vpopmail vchkpw 4096 Jun 18 16:38 .RPV drwx------ 2 vpopmail vchkpw 4096 Jun 18 16:41 tmp Please could help me with this problem because I do not have much experience in this type of migration.

[Dovecot] CRAM-MD5 authentication but plain-md5 password storage.
by Richard 22 Jun '09

22 Jun '09

Hi all, Got a question on configuring dovecot, I'm still new at this so I might be doing this all wrong. I want dovecot to authenticate the mail client using CRAM-MD5 so I've setup the config in dovecot.conf: auth default { mechanisms = cram-md5 passdb sql { # Path for SQL configuration file, see doc/dovecot-sql-example.conf args = /etc/dovecot/dovecot-sql.conf } <snipped> } In my dovecot-sql.conf I've setup the password scheme to be: default_pass_scheme = MD5 Somehow this does not work, the error I see in the logfile is: auth-worker(default): password(info(a)richard5.tld,127.0.0.1): Requested CRAM-MD5 scheme, but we have only MD5 Is there a way to get this working or does this feature only works with passwords stored in plain text ? Thanks! Richard

[Dovecot] dedup in dovecot?
by Roy Sigurd Karlsbakk 22 Jun '09

22 Jun '09

Hi all Deduplicating data is not really a new thing, but quite efficient in mail systems where an email with an nMB attachment may be sent to multiple recipients. This might call for deduplicating data. Is there a way to do this, or is it far off? If I understand the system correctly, usually an MTA is calling dovecot on every single message, meaning the message itself won't necessarily be a duplicate in terms of headers (BCCs and so on). Would it be possible to dedup the content in terms of using separate files for the header and content and then deduping this with hard or symbolic links? Sorry if this is an old question, but I couldn't find anything about it. roy -- Roy Sigurd Karlsbakk (+47) 97542685 roy(a)karlsbakk.net http://blogg.karlsbakk.net/ -- I all pedagogikk er det essensielt at pensum presenteres intelligibelt.
