[Dovecot] Dovecot, pam and OpenLDAP
by Rune Hamnvik 14 Mar '05

14 Mar '05

Hello We have a Dovecot installation using only pop3 where auth data is stored in OpenLDAP and accessed using pam. With Fedora 2 everything has worked fine, but when we upgraded to Fedora 3 we started to get problems. After a while a lot of dovecot processes existed, and error messages was logged in maillog telling that the processes was too old. Then some error messages telling about memory leak was logged. Our /etc/pam.d/dovecot looks like this: #%PAM-1.0 auth required pam_nologin.so auth required pam_stack.so service=system-auth account required pam_stack.so service=system-auth session required pam_stack.so service=system-auth Any idea what is happening?

What problems exist with Thunderbird? Both my wife and I are using Thunderbird with no issues on both OSX and WindowsXP. (No issues that I'm noticing anyway). I'm using 1.0 Test 64: Dovecot v1.0-test64 starting up Frank Simon Windsor wrote: > Hi > > Thanks for the advice, but no luck. > > In the end, I am now using Evolution, which I do not like but it works. > It appears that Kmails IMAP and Thunderbirds IMAP are broken, > particularly kmails! > > Installing Dovecot 1.0.59 improves Dovecots IMAP software, but exposes > flaws for Kmail and Thunderbird! > > So, until the update to KDE, due at the end of March, I will endure > Evolution. > > Thanks, once again > > Simon > > On Sun, 2005-03-13 at 17:40 -0600, F.

I've always had to drop my IMAP connection and reconnect to recognize changes I've made on the server side. A kill -1 to dovecot will only reload the server process and the login auth processes...it won't kill your already established IMAP connection, which as far as I can tell, keeps using old settings. If you are having that many problems, delete all of your subscriptions files and dovecot caches and start from scratch. I've had to do it a few times to get things to work as expected.

[Dovecot] Restrict Imap access
by Sergiu Zaharia 14 Mar '05

14 Mar '05

Hello. I need to restrict access to IMAP ports to a few users, so that all users can use POP3 and just a few of them will be able to access IMAP. I use secure connections POP3s and IMAPs. Is it possible? Also... When I connect to the Dovecot server using Outlook (IMAPs) I get a Warning message,something like: "The server you are connectiing to uses a non verified protection certificate. A chain of certificates ...so on ( I can't translate :) ) Continue using the server? " How can I fix that warning? Thanks

Do you even see the mailbox list? Maybe kmail got somehow confused and recreating the IMAP account entirely would be easiest way to fix it.

[Dovecot] pop before smtp with 'exact' and 'exim4'
by Jools Smyth 13 Mar '05

13 Mar '05

Hello, I just thought I would write this in case its useful to anyone. I've used dovecot for a while, as its so easy to set up, its fast and it and just "works". I recently wanted to be able to send via my server after pop3s authentication. I'm also running debian (testing) which utilises exim4 by default. I found no information about how to do it with this combination of software so went about sorting it out myself. First I got exact : (a pop before smtp daemon) http://adju.st/dist/exact/ After compiling and installing i edited its /usr/local/etc/exact-servers.conf It doesn't support dovecot's log format out of the box, so i created a regular expression entry for it. <server dovecot> order username,address match (Login): (.*) \[(.*)\] </server> I then edited its main configuration, (/usr/local/etc/exact.conf) changing only the user its running on (default mail/mail) to Debian-exim/mail. (so that the state file it creates can be read fine by exim4) I also changed the mail log ownership so that group mail can read them, /usr/local/var/state/exact to drwxr-sr-x 2 Debian-exim mail 1024 Mar 13 16:39 exact and /usr/local/var/run/exact to drwxr-sr-x 2 Debian-exim mail 1024 Mar 12 21:54 exact Exact's exim documentation is not for the most recent version, so I had to locate the correct line to modify. I went into the exim4 configuration files. I use the debian split format configuration. In the file /etc/exim4/conf.d/acl/30_exim4-config_check_rcpt there is a line near the bottom which reads accept hosts = +relay_from_hosts I changed this to accept hosts = +relay_from_hosts : net-lsearch;/usr/local/var/state/exact/rela y I then just set exact to and start/stop in /etc/init.d/exim4 thats all!

Hi I have just upgraded a mail server from dovecot-0.99 to stable (dovecot-1.0.59). My normal desktop email client, kmail is working fine, but outlook keeps producing PLAIN authentication errors, and refusing to authenticate. From dovecot.log, I can see dovecot: Mar 13 10:57:30 Error: auth(default): sql(<xxxxxxxMy Detailsxxxxxxxxxxx>): Password query must return a field named "password" I have tried setting, unsetting disable_plaintext_auth in dovecot.conf, to no avail. What is happening, and what should I do to get all email cleints to work. Simon -- Simon Windsor Email: simon.windsor(a)cornfield.org.uk Tel: 01454 617689 Mob: 07720 447385

Hi dovecot, My dovecot log shows this: Feb 27 03:08:38 eta imap-login: Login: sltam [X.X.X.X] Feb 27 03:09:38 eta imap-login: Disconnected: Inactivity [X.X.X.X] Feb 27 03:10:32 eta dovecot: login: received another "not listening" notification (if you can't login at all, see src/lib/fdpass.c) Feb 27 03:10:42 eta dovecot-auth: Login process has too old (124s) requests, killing it. Feb 27 03:10:42 eta dovecot-auth: Login process 8 disconnected Any clues what it means? Recently I have to restart dovecot several times a day, after I have report that all users cannot login. I am running Debian sarge (2.6.8 kernel) with dovecot version 0.99.14-1 with auth_verbose and auth_debug on. -- Regards, Alan

[Dovecot] Errors when searching large folders
by Mike Jakubik 12 Mar '05

12 Mar '05

I am getting errors from dovecot when trying to search, in large Maildir folders. The folder has 40454 messages and is 371MB in size. The email client is squirrelmail 1.4.3, running on FreeBSD-current. I've had this problem before, and i posted a message here. The author said he would fix this, but it seem the problem is still not resolved. This is the error i get: --- ERROR : Connection dropped by imap-server. Query: SEARCH CHARSET ISO-8859-1 ALL BODY {5} hello BODY {5} there --- At this point the HD led remain on for another 30 seconds or so. Thanks.

[Dovecot] Logging options
by Joebstl Thomas 12 Mar '05

12 Mar '05

Hi, is it possible to configure dovecot's logging so it logs stuff like "User x logged in from IP/Host y and had z new messages" like I'm used from qpopper? That immensely helps when debugging PEBKAC issues. Enabling auth_verbose isnt really helpfull since a failed login generates 4 lines, some even without a pid - so it's a bit hard guessing which log entry belongs to which login attempt or even writing a script which checks for those. Regards, Thomas
