[Dovecot] automatic flag updates
by Aaron VanDevender 24 Mar '05

24 Mar '05

Is there a way to get dovecot to send automatic flag updates? I notice that when I have two clients connected and one of them reads a new message, the server sends a status update which contains the number of unseen messages, but doesn't specifically say which ones have changed. I think the solution to this problem, while not wasting bandwidth, is to issue a unilateral FETCH FLAGS response whenever a flag changes. There doesn't seem to be a way to get dovecot (I'm using 0.99.10) to do this. Can the 1.0-test versions do this? cya .sig

[Dovecot] Hide non-accessable folder from users
by Remy Zandwijk 22 Mar '05

22 Mar '05

Hi all, In our faculty, people keep asking about shared mail folders. With Dovecot up and running this should be no problem. I think we will have about 50 shared folders. I did take a look at the various solutions, but not all of them are useable. For example, I do not want users to create sub-folders in shared folders. This means the symlink option is unuseable. In my opinion, the easiest solution is creating a namespace and create the shared folders in the location of this namespace. Every shared folders gets his own UNIX group ID. Offcourse, this works great. The ony big disadvantage is that every users 'sees' all shared mailfolders, even if the user does not have the proper rights to access the folders. Is there a way to hide the non-accessable folders from users? Best regards, Remy Zandwijk

[Dovecot] strange email client problems
by Gabriel Granger 22 Mar '05

22 Mar '05

I've got some issues with dovecot, that I need to resolve, I only have about 20 users in the office, but the average disk space used by each user is anywhere from 1GB up to at the extreme end of the scale 7GB. I'm using the mailbox format. The server is a P4 2.8 with a 1GB of ram and run off 250GB SATA disks. most users have lots of structured folders going as deep as 6 levels. The problems I'm getting are odd the problems that I'm getting at the moment are "cannot copy mail to sent folder", but sends the message fine, this doesn't happen all the time but happens to everyone but me... I'm using OS X's Mail.app which seems to always work:) all my users are using W2K and either ThunderBird or Mozilla The other problem which I've been made aware of... The users get the "loading message" or "opening messages" and the egg timer goes round but never completes. I managed to clear the problem by getting the user to close their email client and then kill their IMAP processes on the server, when the user logs in again the client responds correctly. Is there something I'm doing wrong with the configuration of dovecot? would using MailDir help, I dont want to migrate from Mailbox unless this change will make things better, I understand their are benefits from using MailDir, but I dont know if I will continue to see the same problems if I migrate. Any help or advise would be great, I should add that everyone is connecting to the server over SSL Gabe

[Dovecot] emulating courier imap

I'm trying this: default_mail_env = maildir:%h/.maildir:INDEX=%h/.indexes:INBOX=% h/.maildir namespace private { separator = . prefix = INBOX. inbox = no } namespace private { separator = . prefix = inbox = yes hidden = yes } but dovecot doesn't appear to be honoring "hidden" - am I missing something? (that is, all my folders appear twice- one under INBOX, the other under root) I tried without the second segment, and makign the first one "inbox=yes" - but then I got two inboxes... -- Internet Connection High Quality Web Hosting http://www.internetconnection.net/

[Dovecot] Mixing mbox and maildir
by Tom Alsberg 21 Mar '05

21 Mar '05

Hi there. I understood that in Dovecot 1.0 it should be possible to mix the usage of mbox and maildir mailboxes. I just downloaded, built, and am testing dovecot-stable-20050304. I'm a bit confused as to the terms of namespaces (haven't read that part of the RFC yet), but this does not seem related. Anyway, when I try specifying: default_mail_env = ~/mail/:INBOX=/var/mail/%u On login I'm immediately disconnected, seeing something like: dovecot: IMAP(user): Failed to create storage with data: ~/mail:INBOX=/var/mail/user in the log file. This seems more like a bug to me (or maybe something in permissions I haven't noticed - but I've checked...) Any way, according to the documentation, it will detect whether ~/mail/ is mbox or maildir - but would that enable having both mbox and maildir in that directory? The goal is, to deploy Dovecot 1.0 at some time, while here there are users who have both maildir and mbox mailboxes (I.E. spool is mbox, ~/mbox is mbox, ~/mail contains some mbox mailboxes for small stuff that users want to be able to access even using /usr/bin/mail, and some larger maildir mailboxes (less critical, or high volume - e.g. mailing lists). How is that possible? Thanks, -- Tom P.S. Thanks again, Timo and rest of developers for this big piece of code - I maintain Dovecot 0.99 in another place and it's by far the most useful IMAP server yet. -- Tom Alsberg - hacker (being the best description fitting this space) Web page: http://www.cs.huji.ac.il/~alsbergt/ DISCLAIMER: The above message does not even necessarily represent what my fingers have typed on the keyboard, save anything further.

[Dovecot] Shared maildirs with symlinking
by Gauthier Vandemoortele 21 Mar '05

21 Mar '05

Hello, I try to set up a shared maildir with symbolink links, but it doesn't work. The main user, from which I would share a mailbox, creates a mailbox named "Commun" with thunderbird. I see on the file system from the server that a directory .Commun is created in his ~/Maildir/ and that the file ~/Maildir/.subscriptions has now such an entry. Right. In ~/Maildir/Commun the permissions are /cur 700 /new 700 /tmp 700 .customflags 600 .imap.index 600 .imap.index.data 600 .imap.index.log 600 .imap.index.tree 600 dovecot-uidlist 600 and as owner MainUser/users (I work on a slackware 10, all the users have by default the group users.) So, I change all the rights to 770 for directories and 660 for other files (I don't forget .Commun itself) Now the other user ; he creates also a folder named "Commun", so that such an entry exists in .subscriptions. As admin, I delete his folder ~/Maildir/.Commun, and create a symbolink link ~OtherUser/Maildir/.Commun pointing to ~MainUser/Maildir/.Commun Now MainUser moves a mail in his folder Commun, always with thunderbird ; OtherUser sees now a message in the "same" folder, but he can't read it. In fact, Thunderbird displays a little icon but without textuel information, like subject, or so. If OtherUser clicks on it, the mailer hangs indefinitly. It's logical, the file created in ~MainUser/Maildir/.Commun has 600 as permissions. On the other hand, OtherUser can move or create a file in his folder Commun, but MainUser does'nt see it, I suppose because his index is not updated. I had read in http://wiki.dovecot.org/SharedFolders that : It's important to have dovecot-shared file created in the shared maildir with the permissions and group ID you want to have access to the mailbox. Dovecot uses the same permissions and GID when it creates index files, dovecot-uidlist file, new mail files, etc. With my experience, it seems that Dovecot creates the file regardless of the permissions of the shared folder. Can someone say how to resolve that ? I use dovecot-0.99.11 Thanks in advance, -- Gauthier Vandemoortele <gauthier.vandemoortele(a)skynet.be> ...

[Dovecot] Loading messages
by Gabriel Granger 19 Mar '05

19 Mar '05

Thanks to all for pointing out the Thunderbird bug workaround, I've got another question Some of my users are complaining that when they select a message, the email client says "Loading Message" and either takes a long time to display a small message or does not display the message at all. Its odd becuase it seems that larger message on these users machines seem to open more quickly then the small 1Kb - 15Kb messages. Looking a little further on the messages that wont open they all seem to be very small in size. Is this a common issue? or something i need to tweak on the dovecot.conf or on the client side? Gabe

[Dovecot] problems with migration to Maildir
by F. Even 19 Mar '05

19 Mar '05

I'm attempting to use Maildir and mbox together until I can finish migrating all mailboxes and figure out issues I'm having with a couple other mailboxes. But, I want to officially start using Maildir as the primary msg. store. Now...when I configure Dovecot as follows, it creates new folders in the ~/mail folder, which is where my mboxes reside: #default_mail_env = #default_mail_env = mbox:~/mail/:INBOX=~/mbox #default_mail_env = mbox:~/:INBOX=~/mbox #default_mail_env = mbox:~/mail:INBOX=~/mbox default_mail_env = maildir:~/Maildir #namespace private { # separator = / # inbox = yes # prefix = # location = mbox:~/mail:INBOX=~/mbox #} #namespace private { # separator = / # prefix = "Maildir/" # location = maildir:~/Maildir #} namespace private { separator = / inbox = yes location = maildir:~/Maildir } namespace private { separator = / location = mbox:~/mail } I would like to have access to the mbox hierarchy, but I want all new folders by default created in ~/Maildir. How do I go about acheiving this? Thanks, Frank
