[Dovecot] Dovecot Wiki
by Timo Sirainen 14 Sep '03

14 Sep '03

I finally got around to cleaning up the MoinMoin pages out of it and added a link to it from main page. I also got dovecot.fi domain, so Dovecot pages can be accessed from http://www.dovecot.fi/ and Wiki is at http://wiki.dovecot.fi/

[Dovecot] Setting up a local shared mailbox
by Peter Clark 14 Sep '03

14 Sep '03

One: I have never set up an IMAP server before, so I thought I would ask first before blindly stumbling around. The problem I am want to solve is this: my wife and I have a "joint" email account that we both want to access (we also have our own personal accounts, but that's beside the point.) I posed the question to my local LUG, and several suggested setting up a local IMAP server so that we can both access it through KMail. Would you concur? If so, is there a tutorial or something similar that gives instructions for setting up dovecot locally? As I said, I've never set up an IMAP server before, and I'm not really sure how to go about it. (I'm running Debian Sid, so the packages are already installed, but I don't know what additional steps need to be taken.) Thanks for your help, :Peter

[Dovecot] Patch for auto-creating home directories
by David S Madole 13 Sep '03

13 Sep '03

I've created a patch that adds a feature that is helpful to my setup. If 'parent_dir_umask' is set in the configuration file, any missing directories in the home directory path are created. The home directory itself is created according to the 'umask' setting, 'parent_dir_umask' is only used for intermediate directories that might need creating. This is useful to me, as I pull user information from a PostgreSQL database. This allows a new account to be created just by populating the database. The directory gets created the first time the user logs in (by Dovecot) or mail is received (by the MTA). As the patch is of modest length, I have included it below. I hope my meager skills are not an insult to the beatiful Dovecot code base!

[Dovecot] Dovecot on Linux 2.6.0-test1-ac1
by Kyler Laird 12 Sep '03

12 Sep '03

I've been using Dovecot on 2.6.0-test1 for quite awhile but today I jumped ahead to test5 and it broke in the way you described. http://dovecot.procontrol.fi/list/dovecot/2003-July/001943.html I used your workaround and now everyone is back in business. Thank you for the help! (I was sweating there for a bit.) --kyler

[Dovecot] Web administration tool
by Timo Sirainen 10 Sep '03

10 Sep '03

Any suggestions for a small web based tool to manage virtual domains/users? I tried to look but didn't really find anything that didn't seem to be tightly integrated with Courier or Cyrus, and I'd rather not spend time writing yet another one of those. I would be using Postfix and Squirrelmail with LDAP or PostgreSQL. On a somewhat related thought, I've been thinking about writing some kind of performance and statistics tool which would at least show the users who are logged in and how much CPU, memory and disk I/O they're eating so that you could see what's happening when load is too high. From Dovecot side that'd be done using a plugin. I'm not sure what the client side would be.. HTML might not be enough. Java maybe. Would Flash be too evil? :)

[Dovecot] Problem with mbox files.
by David Röhr 09 Sep '03

09 Sep '03

I have trouble to get my INBOX-mbox to work properly. I have set the default_mail_env, to this.. "default_mail_env = mbox:~/mail/:INBOX=/var/mail/%u" Since my users are using thier home-dirs to store folders and old mails, and recieving them in /var/mail/username. But when logging in i get this.. Sep 9 12:25:23 angelica imap-login: Login: username [217.151.192.103] Sep 9 12:25:23 angelica imap(username): stat() failed with mbox file /var/mail/username : No such file or directory Just like the file wasn't there?! But checking.. .~ > ls -l /var/mail/username 1200 -rw-rw---- 1 username mail 1222055 Sep 9 12:16 /var/mail/username I can see that it is there, and containing mails.. It's not corrupt or anything like that. And its not a link of any kind. Why am I getting this error? And how do I solve it? I've tested to disable chroots, but get the same error... /d -- ... david röhr | o_ .. unix systems consultant | o/ /\ Solaris, AIX, HP-UX . qbranch system management | /|_, \\ and GNU/Linux Certified. www.qbranch.se / `
