[Dovecot] message-of-the-day feature?
by Steven F Siirila 24 Apr '07

24 Apr '07

For lack of a better name, we are interested in a feature where one could get a notice out to all Dovecot users as quickly as possible, possibly without going through an MTA even. Given a message and a list of userids we could certainly do a mailing on the MDA server itself going through both Postfix and Dovecot LDA. However, we were wondering what other options we might have in Dovecot. For example, would it be possible to place the message into some file which Dovecot periodically checks for, and if the file exists, either present it to the user as a new message, or automatically deliver it at that time via Dovecot LDA? -- Steven F.

Hi, I am using dovecot 1.0 with squirrelmail. But when i use $imap_auth_mech = 'digest-md5' instead of plain, dovecot throws this line: dovecot: Apr 23 09:16:07 Info: imap-login: Aborted login: user=<azher>, method=DIGEST-MD5, rip=127.0.0.1, lip=127.0.0.1, secured and user can't login.

[Dovecot] SASL Problems
by Phillip T. George 23 Apr '07

23 Apr '07

Hello all, I seem to be having a problem with SASL. It doesn't seem to work with Outlook. Upon searching a bit, I found that I need to enable "login" for auth mechanisms. However, when I do that, (after I stop and start dovecot and postfix), and then try to use SMTP auth using Outlook, it causes postfix to crash. It works fine with Thunderbird still though. Any ideas as to what the cause might be? I'm using Dovecot 1.0.0 and Postfix 2.3.5. Thanks, Phillip

[Dovecot] Trying to explain mutt+dovecot(ssl) to myself :(
by Wilkinson, Alex 23 Apr '07

23 Apr '07

Hi all, I have recently migrated my mail from courier-imap to dovecot. In doing so, I finally configured mutt to connect to imaps (SSL). In the end I got it all working. I then sat back and thought: "I kinda don't understand the SSL/TLS part even though it works". And I hate setting stuff up and not truely understanding the mechanics of it. So I started to write about it and am stuck. Can those that _understand_ mutt+ssl have a read of what I wrote to myself and give me your $00.02 worth (corrections etc). Trying to explain mutt+ssl and getting it all wrong --------------------------------------------------- * mutt(with openssl support built in) initiates with a "SSL-Client-Hello" to SSL on port 993 i.e. mutt's capabilities (algorithms, SSL version etc). * dovecot:993 compares mutt's CipherSuites with its own. Of the CipherSuites mutt and dovecot have in common, dovecot:993 chooses the _most_ secure algorithm. * Dovecot:993 will then tell mutt what it has decided to use and assigns a Unique session ID. From now on all communication is via this ID. * Now that the CipherSuite is set between mutt and dovecot, dovecot sends its SSL certificate to mutt [/usr/local/share/dovecot/certs/dovecot.pem]. mutt then uses dovecot's corresponding public key [/usr/local/share/dovecot/private/dovecot.pem] to verify that the ceritificate is authentic. * once mutt has verified that the certificate is authentic ... and here I got unstuck.

[Dovecot] deliver failing to execute sendmail (sieve)
by Justin McAleer 21 Apr '07

21 Apr '07

I have apparently done something to mess up my test installation, as deliver's attempts to send messages now fail with the following error: deliver(user(a)example.com): execv() failed: No such file or directory In these cases, I have sieve rules trying to send messages. It had been working though, and I've tried going through all the changes I made yesterday (related to dictionary quota debugging) to find what could be wrong, but no luck so far. So, I was hoping for suggestions. Basically, deliver seems to not know where sendmail is. I have sendmail_path set in dovecot.conf (never changed that), yet when deliver tries to pull the location via deliver_set->sendmail_path, it's just returning an empty string. If I hard-code the location in smtp-client.c, it works again. Any ideas?

[Dovecot] POP3 log in failure after switch to dovecot from Cyrus

I can set up and access a dovecot pop3 account using outlook express fine. I can telnet into it fine. However, GFI FaxMaker is failing to log in. I assisted a client in switching his web site, including email from one server (FreeBSD) which was using Cyrus to a Redhat 4.0 server using dovecot version 0.99.11 Here's the listing of dovecot -n: dovecot -n Usage: dovecot [-F] [-c <config file>] Fatal: Unknown argument: -n The GFI Faxmaker polls the pop3 account every minute so we're getting a lot lf these messages in the log file: Apr 19 19:51:28 server name pop3-login: Aborted login [::ffff:<ip address here>] Again, I can telnet in to the account from that server. I verified all the log in credentials are correct but it still is failing to log in. Any ideas?

[Dovecot] Maillog rotates, but dovecot still writes logs into old logfile?
by Mart Pirita 20 Apr '07

20 Apr '07

Tere. I use: log_path = /var/log/maillog info_log_path = /var/log/maillog And into /var/log are: maillog maillog.1 maillog.2 maillog.3 Now when log files are rotating at 04:00 (maillog > maillog.1) dovecot still keeps login into maillog.1 and not into maillog, where sendmail, etc writes logs. The only solution I did found, is adding into /etc/logrotate.d/syslog command to restart dovecot: /var/log/maillog { postrotate /usr/bin/killall -HUP syslogd /etc/rc.d/init.d/dovecot restart >/dev/null 2>&1 endscript } Any other solution? -- Mart

[Dovecot] MANAGESIEVE patch v4 for dovecot 1.0.rc28
by Stephan Bosch 19 Apr '07

19 Apr '07

Hello dovecot users, I have updated the MANAGESIEVE patch to fix the currently known small problems with the protocol implementation. It is designed for rc28, but also compiles cleanly with the current cvs branch_1_0. Change Log V4 ------------- - Added managesieve_implementation_string setting to the managesieve configuration. This can be used to customize the default "IMPLEMENTATION" capability response (as requested by John Peacock). - Denied ANONYMOUS login until proper support is implemented - Fixed problem with authenticate command regarding continued responses. In V3 only initial response would work. Problem was caused by rc2 -> rc28 upgrade. One of the clear reasons why code duplication is a very bad idea. - Fixed readlink bug as indicated by Timo: return value of readlink can also be -1. - Fixed bug in the regular file rescue code, as introduced in the previous version. Used stat instead of lstat. This caused the symlink to be rescued subsequently in the next activation, thus still overwriting the initially rescued script. This patch still includes (yet another) instance of the CMU Sieve source, as explained in one of my previous e-mails (http://dovecot.org/list/dovecot/2006-July/015016.html) It can be downloaded at: http://sinas.rename-it.nl/~sirius/dovecot-1.0.rc28-MANAGESIEVE-v4.diff.gz A design related README is located at src/managesieve after applying the patch. Have fun testing the patch. Notify me when there are problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl IRC: Freenode, #dovecot, S[r]us

[Dovecot] Duplicate E-mail Problem
by Phillip T. George 19 Apr '07

19 Apr '07

Hello all, Definitely congrats on the 1.0.0 release! Anyway, I'm having a problem, that may or may not be related to Dovecot. Specifically, duplicate (and sometimes triplicate) emails are appearing. These emails have exactly the same queue ID, so its not that they were sent multiple times. These dup emails do not show up to me ever. Postfix is being used as the SMTP, and it hands it over to procmail. I set up procmail's verbose logging feature for that user and on the duplicate emails that he receives, it shows only ONE write to a file for that specific subject of email. Tonight / this morning I'll be tracking down to see if this duplicate for sure happens in IMAP. Note: Its possible that part of the problem is he leaves two IMAP clients open at the same time (Netscape I think). I'm going to verify that with him. Any ideas? I'm NOT trying to blame Dovecot, I'm just trying to explore options. Right now its looking fairly bad for Dovecot though....I mean, what else is there after the mail is delivered to the appropriate place in the mailbox? Software versions: postfix 2.3.8 procmail 3.22 dovecot 1.0.rc28 Thanks, Phillip

http://dovecot.org/releases/dovecot-1.0.0.tar.gz http://dovecot.org/releases/dovecot-1.0.0.tar.gz.sig It took almost 5 years, but it's finally ready. I'm not expecting to release v1.0.1 anytime soon, unless someone's been sitting on a major bug just waiting for v1.0 to be released. :) People wanting new features should start testing the upcoming v1.1. http://dovecot.org/nightly/ contains now snapshots from CVS HEAD. It already has tons of new features. I've been using it myself for half a year, so it should be mostly stable too. I'll write a separate mail about this later.

[Dovecot] help with static userdb
by Kyle Wheeler 18 Apr '07

18 Apr '07

Hey, This may be a dumb question... I'm trying to set up 1.0 with a static userdb, and I'm getting stuck. I have: userdb static { args = uid=500 gid=500 home=/domains/%d/%n } When I attempt to log in as, say, kyle(a)memoryhole.net (via telnet, so I *know* I'm logging in as that user), the debug log says that it thinks my home directory is "/domains//kyle". I even tried, just to check what might be going on: args = uid=500 gid=500 home=/domains/%u/%d/%n It then thought my home directory was "/domains/kyle//kyle". Can anyone help me? Where might that be getting cleared? ~Kyle -- The more men you make free, the more freedom is strengthened and the ... greater is the security of the State. -- Frederick Douglas, Nov 17, 1864

[Dovecot] lazy_expunge vs mulberry
by Frank Cusack 18 Apr '07

18 Apr '07

I've configured the lazy_expunge plugin exactly like it says on the wiki. I can't seem to configure Mulberry to find the new namespaces. Any hints? I notice that the wiki says to use / as the separator. Mulberry has a setting for this, and the default is '.'. Leaving this as '.' in Mulberry and / in dovecot seems to work fine. (But I still can't access the .EXPUNGED or other namespaces.) Another page on the wiki says that the default separator for maildir is '.'. Why does the lazy_expunge page suggest using '/'? I'm very confused about namespaces. -frank
