[Dovecot] Multiple instances and/or separate certificates per email address
by Simon L Jackson 17 Apr '09

17 Apr '09

Hi, We have a mail server with multiple instances of Postfix each listening on a different IP address to create a set of virtual mail servers. There are various reasons why separate instances of Postfix seems to work best to achieve this goal, but I wont divert into that discussion here. I would like so match this with Dovecot. The listening side isn't a problem as Dovecot can listen on multiple explicit IP addresses. However, we would prefer a separate SSL certificate for each virtual mail server i.e. for each IP address. Would it be better to have multiple instances of Dovecot on the server (not sure what the issues might be with this) or would it be better/easier to be able to specify separate SSL certificates for each listen address, since there isn't any other reason I can see to have multiple instances. Any thought? Is there a way to do this now or would this be a new feature request?

Re: [Dovecot] v1.1.14 and v1.2.rc3 released

I was already going to report a bug with rc2 where the server crashed when a client tried to access a Maildir folder with wrong permissions. After installation of rc3 the server correctly reports the wrong permissions and keeps running: IMAP(user1): stat(/var/spool/mail/user1/Maildir/tmp) failed: Permission denied (euid=12807(user1) egid=200(grp1) missing +x perm: /var/spool/mail/user1/Maildir) Great work, thanks Timo! -- Wolfgang Friebel Deutsches Elektronen-Synchrotron DESY Phone/Fax: +49 33762 77372/216 Platanenallee 6 Mail: Wolfgang.Friebel AT desy.de D-15738 Zeuthen Germany

[Dovecot] v1.1.14 and v1.2.rc3 released
by Timo Sirainen 17 Apr '09

17 Apr '09

http://dovecot.org/releases/1.1/dovecot-1.1.14.tar.gz http://dovecot.org/releases/1.1/dovecot-1.1.14.tar.gz.sig http://dovecot.org/releases/1.2/rc/dovecot-1.2.rc3.tar.gz http://dovecot.org/releases/1.2/rc/dovecot-1.2.rc3.tar.gz.sig Fixed lots of bugs in v1.2 related to shared mailboxes and virtual mailboxes. Keep on testing and sending bug reports and hopefully we'll get v1.2.0 release out soon. :) Also v1.3 branch has started and it's coming along nicely. Multi-dbox is working and looks like its performance is very nice. LMTP server is basically implemented, except master process doesn't start it. Adding the master code started becoming so annoying that I think I'll finally finish the master process rewrite, or at least the most important parts of it. So looks like v1.3 might become v2.0 after all. v1.1.14 2009-04-16 Timo Sirainen <tss(a)iki.fi> * IMAP: Don't allow APPEND to specify INTERNALDATE more than 2 hours into future. With Maildir future INTERNALDATEs may mess up incremental backups. - Date: header was always being added to cache file when saving messages, even if clients didn't really want it. This caused POP3-only users to have dovecot.index.cache file unneededly. - Character set conversion in specific mails may have caused Dovecot to allocate all the available memory (in default configuration dying after having allocated 256 MB). This happened only while searching messages. - Message address parser didn't handle empty group:; correctly. - imap/pop3-login: Don't crash when shutting down and destroying clients. - deliver wasn't using mail_access_groups setting. - mbox: When doing autodetection, if mbox didn't find an existing mail directory it just went and created it anyway, instead of failing the storage creation. - Fixed some error handling in maildir and index code. v1.2.rc3 2009-04-16 Timo Sirainen <tss(a)iki.fi> * IMAP proxy no longer simply forwards tagged reply from remote authentication command. It's now done only if the remote server sent a [resp-code], otherwise all failure strings are converted to Dovecot's "Authentication failed." to make sure that if remote isn't using Dovecot it won't reveal user's existence. + Quota roots can now specify which namespace's quota they're tracking. This is probably the most useful for giving public namespaces a quota. + Added imap_idle_notify_interval setting. - Fixes to shared mailbox handling - Fixes to virtual mailboxes - Fixed compiling with some FreeBSD and NetBSD versions - THREAD REFS still might have returned one (0) at the beginning. - deliver wasn't using mail_access_groups setting. - Fixed some error handling in maildir and index code.

[Dovecot] Postfix, Dovecot SASL and Entourage smtps authentication fails.
by Mart Pirita 17 Apr '09

17 Apr '09

Tere. Recently just migrated from Sendmail 8.14.3 to Postfix 2.5.6 and switched from Cyrus-sasl 2.1.22 to Dovecot 1.1.13 sasl, all are compiled from source and I have used Dovecot for a long time, since alpha versions. Everything worked well for Outlook Express, Outlook and Thunderbird clients, but Microsoft Entourage 2004 or 2008 clients smtps fails - "Authentication failed because Entourage doesn't support any of the available authentication methods." Similar case like - http://archives.neohapsis.com/archives/postfix/2008-09/thread.html#145 I tried everything, the config is like described in Postfix and Dovecot sites - http://wiki.dovecot.org/HowTo/PostfixAndDovecotSASL I also tried in main.cf smtpd_sasl_security_options =forward_secrecy like described in http://www.postfix.org/postconf.5.html#smtpd_sasl_security_options But none helped. So I switched back to Cyrus-sasl and Entourage works well like before with sendmail. I started to search what may be the reason, and seems with Dovecot sasl Postfix wont advertise needed stuff in ehlo: With Cyrus: telnet localhost 25 Trying 127.0.0.1... Connected to localdomain.localhost. Escape character is '^]'. 220 my.host.ee ESMTP EHLO example.com 250-my.host.ee 250-PIPELINING 250-SIZE 250-ETRN 250-STARTTLS 250-ENHANCEDSTATUSCODES 250-8BITMIME 250 DSN starttls 220 2.0.0 Ready to start TLS With dovecot: telnet localhost 25 Trying 127.0.0.1... Connected to localdomain.localhost. Escape character is '^]'. 220 my.host.ee ESMTP EHLO example.com starttls 220 2.0.0 Ready to start TLS Setting with Cyrus in main.cf smtpd_tls_auth_only = no gives even more but still nothing with Dovecot: telnet localhost 25 Trying 127.0.0.1... Connected to localdomain.localhost. Escape character is '^]'. 220 my.host.eeESMTP EHLO example.com 250-my.host.ee 250-PIPELINING 250-SIZE 250-ETRN 250-STARTTLS 250-AUTH PLAIN LOGIN 250-AUTH=PLAIN LOGIN 250-ENHANCEDSTATUSCODES 250-8BITMIME 250 DSN So is this a Entourage or Dovecot or Postfix bug? I really like to drop the Cyrus and use only Dovecot sasl. Any hint is welcome. -- Mart

[Dovecot] public folders question
by Xueron Nee 17 Apr '09

17 Apr '09

Hi, Shared folders is ok now. and when I create a public folder follow the doc http://wiki.dovecot.org/SharedMailboxes/Public, I can not get the boxes listed. namespace: type: public separator: / prefix: public/ location: maildir:/home/data/public:INDEX=~/Maildir/public list: children # ls /home/data/public/ -a . .. dovecot-shared .test1 .test2 .test3 And then, I checked the shared folders created by 'setacl' command, and add a dovecot-acl-list file in the root public folder, ok, I got it. # cat /home/data/public/dovecot-acl-list 1239108915 test1 so, 'dovecot-acl-list' should be created manually or any other methods? Thanks! -- Xueron Nee http://www.xueron.com

[Dovecot] Is there any more detailed docs about dict configuration
by Xueron Nee 17 Apr '09

17 Apr '09

Hi, I am looking for some help on dict configration. I'm trying to config shared and public mailbox, and use sql as acl backend. Here is my config: table: CREATE TABLE `shared_dict` ( `id` int(10) NOT NULL AUTO_INCREMENT, `from_user` char(50) NOT NULL, `to_user` char(50) NOT NULL, `status` int(10) NOT NULL DEFAULT '1', PRIMARY KEY (`id`), KEY `from_user` (`from_user`), KEY `to_user` (`to_user`) ) dovecot-dict-sql.conf map { pattern = shared/shared-boxes/user/$from/$to table = shared_dict value_field = status fields { from_user = $from to_user = $to } } dovecot.conf acl_shared_dict = proxy::shared_dict It works, and when i use 'setacl', it can add a record. All I want are some more detailed docs about the `pattern' line, and such as how to add a `group' function. :) Detailed on quota/expire dict configration are welcome, too. :) Thanks! -- Xueron Nee http://www.xueron.com

[Dovecot] Public mailboxes configuration to receive mails
by Didier Faugeron 17 Apr '09

17 Apr '09

Hello, I would like to know how to use Public mailboxes in my Dovecot environment (dovecot 1.2.beta4) Currently my dovecot server is only used for mailbox user. The Postfix master.cf is configured with the following line: "dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/libexec/dovecot/deliver -d ${user}" Both dovecot and postfix use LDAP requests for authentication and users data retrieving. However I don't use userdb database to get the users home directory but an userdb static instruction : "args = uid=vmail gid=vmail home=/data/maildir/%1Lu/%Lu allow_all_users=yes" I have configured my dovecot.conf to create a namespace Public, and it works fine: an user who have read/write access(ACL) to a public mailbox can subscribe to it and read/copy mails. My problem is to deliver mails in this public mailbox. I don't know how to do it. Therefore, first question: is it possible to deliver mails to a public mailbox through the LDA/Postfix ? If yes, please could you tell me how to configure LDA/Postfix and Dovecot in order to accept and deliver mails to users mailboxes and to public mailboxes ? I assume that the main modifications should be done in the master.cf of Postfix. Could you please specify and clarify what modifications are required ? Find below my dovecot -n output and dovecot-ldap.conf. Thank you in advance for your help and your feedback.

[Dovecot] Could sharing a folder with other users cause a loss of emails?
by Alfred Nutile 17 Apr '09

17 Apr '09

we are trying to figure out how and email box is not empty. All we did was /mail/user1 /mail/user2 /mail/shared ln -s /mail/shared /mail/user1/shared ln -s /mail/shared /mail/user2/shared Perms are fine and people where dropping emails in here fine. We added a third one and the user also right clicked in their IMAP client and added a subfolder. It was around that time they where gone. Could any of these actions cause that? PS it is not a mbox layout. Thanks!

[Dovecot] Coredump using virtual folder.
by Matthias Rieber 17 Apr '09

17 Apr '09

Hi, I'm using dovecot 1.2rc2 and I have the following issues with the virtual folder: 1. The virtual folders are flagged with \Noselect and at least thunderbird does not offer to select them. Adding them to the subscriptions file works fine and the folder can be used after that. 2. Two basic virtual work just fine like: $ cat virtual/all/dovecot-virtual INBOX INBOX.Ordner.work.archive.* all and $ cat virtual/unseen/dovecot-virtual INBOX unseen But the third one does not work: $ cat virtual/talk/dovecot-virtual virtual.all inthread x-references2 x-mailbox INBOX The IMAP Client says Unkown server error, the server logs look like this: ... dovecot: Info: IMAP(matthias): virtual: data=~/Maildir/virtual dovecot: Info: IMAP(matthias): fs: root=/home/matthias/Maildir/virtual, index=, control=, inbox= dovecot: Info: IMAP(matthias): Namespace INBOX.: Using permissions from /home/matthias/Maildir: mode=0700 gid=-1 <access happens here> dovecot: Info: IMAP(matthias): Loading modules from directory: /usr/local/lib/dovecot/imap dovecot: Info: IMAP(matthias): Module loaded: /usr/local/lib/dovecot/imap/lib20_fts_plugin.so dovecot: Info: IMAP(matthias): Module loaded: /usr/local/lib/dovecot/imap/lib20_virtual_plugin.so dovecot: Info: IMAP(matthias): Module loaded: /usr/local/lib/dovecot/imap/lib20_zlib_plugin.so dovecot: Info: IMAP(matthias): Module loaded: /usr/local/lib/dovecot/imap/lib21_fts_squat_plugin.so ... kind regards, matthias
