Hello again :), I try to use dictionary proxy server to replace my precedent configuration (direct use of dict in plugin quota). Before, i have this configuration in my dovecot.conf : ## Dictionary server settings dict { } ## Plugin settings plugin { # quota = 10 Mo quota = dict:storage=10240 mysql:/etc/dovecot/dict-quota.conf } And after, to use proxy, I have this configuration in my dovecot.conf : ## Dictionary server settings dict { quota = mysql:/etc/dovecot/dict-quota.conf } ## Plugin settings plugin { # quota = 10 Mo quota = dict:storage=10240 proxy::quota } My dict-quota.conf doesn't change : connect = host=localhost dbname=dovecot user=dovecot table = quota select_field = current where_field = path username_field = username My dovecot.info file : dovecot: 2006-07-23 15:07:01 Info: IMAP(test): Effective uid=1019, gid=1019 dovecot: 2006-07-23 15:07:01 Info: IMAP(test): Loading modules from directory: /usr/lib/dovecot/modules/imap dovecot: 2006-07-23 15:07:01 Info: IMAP(test): Module loaded: /usr/lib/dovecot/modules/imap/lib01_quota_plugin.so dovecot: 2006-07-23 15:07:01 Info: IMAP(test): Module loaded: /usr/lib/dovecot/modules/imap/lib02_imap_quota_plugin.so dovecot: 2006-07-23 15:07:01 Info: IMAP(test): maildir: data=/home/test/Mail dovecot: 2006-07-23 15:07:01 Info: IMAP(test): maildir: root=/home/test/Mail, index=/home/test/Mail, control=, inbox= dovecot: 2006-07-23 15:07:01 Info: IMAP(test): dict quota: uri = proxy::quota dovecot: 2006-07-23 15:07:01 Info: IMAP(test): dict quota: byte limit = 10485760 dovecot: 2006-07-23 15:07:01 Info: IMAP(test): dict quota: count limit = 0 dovecot: 2006-07-23 15:07:01 Info: imap-login: Login: user=<test>, method=plain, rip=82.228.176.60, lip=192.168.1.60 When i use the proxy configuration, i have this error : dovecot: 2006-07-23 15:07:51 Error: dict: sql dict: commit failed: Not connected to database dovecot: 2006-07-23 15:07:51 Error: IMAP(test): dict_quota: Couldn't update quota dovecot: 2006-07-23 15:07:51 Error: dict: sql dict: commit failed: Not connected to database dovecot: 2006-07-23 15:07:51 Error: IMAP(test): dict_quota: Couldn't update quota dovecot: 2006-07-23 15:07:51 Error: dict: sql dict: commit failed: Not connected to database dovecot: 2006-07-23 15:07:51 Error: IMAP(test): dict_quota: Couldn't update quota dovecot: 2006-07-23 15:07:52 Error: dict: sql dict: commit failed: Not connected to database dovecot: 2006-07-23 15:07:52 Error: IMAP(test): dict_quota: Couldn't update quota And in MySQL log : 060723 15:07:01 460 Connect Accès refusé pour l'utilisateur: 'dovecot'@'@localhost' (mot de passe: NON) 060723 15:07:45 461 Connect Accès refusé pour l'utilisateur: 'dovecot'@'@localhost' (mot de passe: NON) It try to connect with 'dovecot'@'@localhost'...

[Dovecot] POP does not seem to be working
by Gerard 23 Jul '06

23 Jul '06

OK, I am brand new to this so please bear with me. I have an FreeBSD 6.1 STABLE system. Postfix is installed with qpopper. The mailboxes are standard mbox format. I just installed Dovecot. At some point I want to update to a mdir format, etc., but quite frankly I do not know how to go about that. In any case, I shut down qpopper and started Dovecot. I modified the Dovecot.conf file SSL settings (turned them off) since I do not have the files it needs built yet. Anyway, when using a mail client on another PC on my network, although it makes a connection, no mail is ever downloaded. Ther is mail in the folders however. Obviously I am doing something really wrong, but I am not sure what. I would sure appreciate any assistance available. The only information I have is in the 'log' file which shows the a pop3-login, the user name, method=PLAIN, and two numeric addresses. Thanks! -- Gerard Seibert gerard(a)seibercom.net

[Dovecot] help with authentication - cpanel
by allan hardy 22 Jul '06

22 Jul '06

I am trying to install dovecot as a second pop3 service in my RH9 system. It is a Cpanel based system using Courier for primary IP By primary I mean all the other domains use courier on xxx.xxx.xxx.21 port 110 I have a domain with special pop3 needs that is dedicated to xxx.xxx.xxx.22 port 110 The two mail systems are installed, I can tell via telenet that dovecot is listening and responding on the desired IP and port Cpanel is the tool being used by all domains to create mail accounts and hence setting the 'policy' for the mailboxes, userdb and passdb information. I am trying to make dovecot use those files and can't get past authentication. What I guess I don't know is the encryption type being used by Cpanel Any help appreciated.!!!! What Cpanel appears to do for authentication is use a passwd and shadow file for each domain, placed as follows: /home/accountname/etc/domainname/passwd holds the list of mail accounts names /home/accountname/etc/domain/shadow holds the passwords This is the message log from a telnet session on local machine: dovecot: Jul 22 13:45:27 Info: auth(default): client in: AUTH 1 PLAIN service=POP3 secured lip=xxx.xxx.179.22 rip=xxx.xxx.179.22 resp=AGFsbGFuAHRlc3Q= dovecot: Jul 22 13:45:27 Info: auth(default): shadow(allan,xxx.xxx.179.22): password mismatch dovecot: Jul 22 13:45:29 Info: auth(default): client out: FAIL 1 user=allan dovecot: Jul 22 13:45:36 Info: pop3-login: Aborted login: user=<allan>, method=PLAIN, rip=xxx.xxx.179.22, lip=xxx.xxx.179.22, secured ~ This was in the shadow file: ---Shadow file entry allan:$1$V0lG6T6P$eNQoX3J3N5RJNxT5yH8gz1::::::: These are my relevant (At least I think they are relevant) dovecot.conf settings: disable_plaintext_auth = no ssl_disable = yes auth default { mechanisms = plain login anonymous passdb shadow { /home/xxxxxx/etc/xxxxx.com/shadow } userdb passwd-file { # Path for passwd-file args = /home/xxxxxxx/etc/xxxxx.com/passwd } --PAM is commented out As a side note, I tried to see if I could tell from the courier setup how it was authenticating. The courier/etc/pop3d file was set POP3AUTH="" And there was a note "To advertise the SASL capability, per RFC 2449, uncomment the POP3AUTH variable" So it this may indicate sasl is being used, what ever that means

[Dovecot] Dovecot and quotas
by mikael 22 Jul '06

22 Jul '06

Hello, I have succesfully installed dovecot version 1.0.rc2 on my Debian Sarge. I have configured quotas (just for tests) like this : == dovecot.conf == ... auth default { mechanisms = plain passdb pam { } userdb passwd { } } protocol imap { mail_plugins = quota imap_quota } plugin { # quota = 10 Mb quota = dirsize:storage=10240 } ... ================== Quotas works without problem : 10Mb for all users... But i would like quotas per user and kept thi default value of 10Mb... How to override this default value ? How to do peruser-quota with "passwd" userdb (or "passwd-file") ? Really thanks for your help, -- Mikaël,

[Dovecot] cmusieve plugin
by Stuart Sears 21 Jul '06

21 Jul '06

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi guys I have been doing a lot of searching, but maybe I am being dim (not unheard of!). I have dovecot-1.0rc2 built and running on Fedora Core 5. The wiki page (dated yesterday) states that I need the cmusieve plugin to use sieve scripts with the dovecot lda. Is this a new development? They seem to work quite happily on my soon-to-be retired 1.0-beta7 debian box without an extra plugin. secondly, if it is now necessary, where do I get this plugin from? (this may be the dim part) I have a cvs checkout of the dovecot sources, but I see nothing obviously connected to cmusieve anywhere in the source tree If this is in a different module, then can someone let me know the name of it, so that I can check it out of CVS as well?

[Dovecot] Migrating to dovecot
by Johann Spies 21 Jul '06

21 Jul '06

I do not have much experience in setting up imap servers - only that I have tried several and experienced the same problem with all of them. I suppose that is because I do not really know the in's and out's of an imap server. What I want to do is to setup an IMAP server on my PC with full access to all the emails already there in a maildir structure. I have the following setup: fetchmail -> procmail -> maildir exim for outgoing mail. When I install an imap server, I loose access to my present emails in ~/Mail and most imap-servers (dovecot included) seems to create a new structure within ~/Mail. ~/Maildir is a symlink to ~/Mail. Now my questions: 1. How do I set up dovecot to serve the present maildir to the user? 2. Related to 1: How do I migrate my emails to the new imap-maildir structure without losing any? 3. How would my present procmail-setup change? At the moment I have entries like the following: MAILDIR=$HOME/Mail # you'd better make sure it exists DEFAULT=$MAILDIR/Ander/new # completely optional :0: * X-Spam-Flag: YES saspam/new :0: * ^List-Id: <users.spamassassin.apache.org> spamassassin/new ...

I'm using dovecot on our new mail server and it is pretty good. But I have a problem regarding quota limits, I am using quota plugin on imap, pop3 and LDA, the deliver agent blocks new messages for delivery, like hard quota. I'd like to use LDA with quota plugin regarding soft quota. Thanks for any clues, -- Philipe Gaspar Universidade Salvador Fone:+55 (71) 3273-8592
