[Dovecot] 200 pop3-login processes
by Zbigniew Szalbot 03 May '07

03 May '07

Dear all, I am using dovecot 1.0.0 and have only 5 pop3 users. However, I have counted over 200 pop3-loging processes. I just wonder if it is normal for dovecot (has been running maybe for 2-3 weeks after installing the stable verion). Thanks! -- Zbigniew Szalbot

[Dovecot] Migrate from mlbox to maildir, lock problem
by Sylvain Nemtua 02 May '07

02 May '07

Hi We've been using dovecot successufly for few month. Previous setup : solaris 8, postfix+LDA, mbox + index on NFS (Netapp), 2500 accounts Everything shared overs NFS, multiple servers connect to index, mbox. mail_location = mbox:/var/mail/mbox/%u:INBOX=/var/mail/%u:INDEX=/var/mail/indexes_dovecot/%u We had at first some issue with mbox locking, using lock_method = dotlock solve the issue. The problem seemed to be with fcntl. I Migrate to maildir to ease administration to use maildir quota I use mb2md-3.20.pl to migrate the mbox everything works smooth. Actual setup : solaris 8, postfix+LDA, maildir + index + control on NFS (Netapp) I change the mail_location settings to mail_location = maildir:/var/mail/maildir/%u:INDEX=/var/mail/indexes_dovecot/%u:CONTROL=/var/mail/dovecot_control/%u And now I'm facing new locking issue : Errors on user loging, users leaving mail on server downloading the same mail over and over. Numerous entries in log files : May 2 11:19:03 gregorie dovecot: [ID 107833 mail.error] POP3(carini): Maildir /var/mail/maildir/carini sync: UID inserted in the middle of mailbox (13 > 1, file = 1178097228.P16222Q0M452645.yder,S=22935:2,) May 2 11:19:03 gregorie dovecot: [ID 107833 mail.info] POP3(carini): Disconnected: Mailbox is in inconsistent state. top=0/0, retr=0/0, del=0/0, s ize=0 May 2 11:19:03 gregorie dovecot: [ID 107833 mail.error] POP3(carini): Couldn't init INBOX: Internal error occurred.

[Dovecot] How to use option allow_nets?
by Bernd Kuhls 02 May '07

02 May '07

Hi, according to http://wiki.dovecot.fi/PasswordDatabase/ExtraFields/AllowNets there exists an option allow_nets to restrict IP ranges from where users are allowed to login to Dovecot. I am using Debian Etch with the official Dovecot packages: # dpkg -l | grep dovecot ii dovecot-common 1.0.rc15-2 ii dovecot-imapd 1.0.rc15-2 ii dovecot-pop3d 1.0.rc15-2 using a mostly unchanged dovecot.conf. I tried to add the line allow_nets=127.0.0.0/8,192.168.0.0/16 in the block passdb pam { which is the default enabled auth code in Debian. When starting Dovecot I get this error message: # /etc/init.d/dovecot start Starting mail server: dovecot Error: Error in configuration file /etc/dovecot/dovecot.conf line 777: Unknown setting: allow_nets According to the Dovecot changelog > 2006-02-27 18:46 Timo Sirainen <timo.sirainen(a)movial.fi> > > * src/auth/: auth-request.c, auth-request.h: Added "allow_nets" > extra field. If set, the user can log in only from within the > given networks (hope the code is correct...) the option exists since February 2006, while the Debian package was released in December 2006. What I am doing wrong? Using TCP wrappers instead seems not to be an option according to http://dovecot.org/list/dovecot/2006-April/012476.html Greetings, Bernd Kuhls

[Dovecot] Best authentication option
by Eric 02 May '07

02 May '07

Dear Dovecot experts, I have a small home server debian based, with postfix/dovecot/squirrelmail installed locally and working. Dovecot is used non-secured (no imaps) but only on the 192.168.0.100 address (address of the server on the local network). I want to use squirrelmail to read my email from outside. Squirrelmail can configured to access it in particular, either through cram-md5 or login auths. In that situation, is it better (I mean more secure) to use : 1) auth mechanim = cram-md5 or 2) auth mechanism = plain (using PAM authentication for dovecot) ? That will determine my dovecot configuration. Thank you Eric

[Dovecot] Strange directory created at dovecot launch
by Eric 02 May '07

02 May '07

I installed dovecot from scratch and compiled it from 1.0.0 source. Installed in /usr/local. Now everytime I launch dovecot it creates and uses /usr/local/var/lib/dovecot and /usr/local/var/run/dovecot directories. For the latter I found the modifications to do in dovecot.conf for using /var/run/dovecot instead, but for the former I see nothing about such directory in dovecot.conf. What happens ? How can I configure it so that dovecot uses /var/lib/dovecot instead ? Thank you Eric

[Dovecot] Migrate from dovecot to dovecot.. new server
by Lars Johansen 02 May '07

02 May '07

Hi We have been running a dovecot server for some time.. users connect with pop. Now this server is going to be substituted with a new one.. before we used mbox, but now we will move to maildir! I have done some testing transfering the mail with the mb2md script, the conversion works correctly, but users gets duplicates since they selected "keep mail on server" I have googled for the problem, and set pop3_reuse_xuidl=yes and pop3_uidl_format = %08Xu%08Xv is the same on both servers.. but no luck. My first tought was to script in an X-UIDL header for each mail that was converted.. but that wont work since the mail already downloaded by the client didnt contain that header.. is there anyone that has some experience with this, or knows if its possible? Many Greetings, Lars Johansen

[Dovecot] Courier-imap + dovecot simultaneously?
by Charles Marcus 02 May '07

02 May '07

Hi everyone, I have a client I've been trying to talk into switching from courier to dovecot, but the owner of the company wants me to set up two different accounts in Thunderbird (I finally got him switched to that from outlook express), one accessing his account through courier, and one through dovecot, so he can compare the speed... Is this even possible? I've never tried it before, so before I spend a lot of time, I want to know if I'd be wasting it (my time)... Thanks, -- Best regards, Charles
