It's my server and it's still running and working properly. Dovecot version is (as on the newer server) beta3, but the first Dovecot running was beta2 I think. Imap works properly on that server. Anyway Dovecot shouldn't crash ever if the index files are broken!

[Dovecot] Shared Folders Problem. Bug?
by Adam M. Dunn 16 Mar '06

16 Mar '06

I'm trying to get shared folders to work, and I've noticed a few issues. I created a private and public namespace, the private one with autodetection for Maildir or Mbox, and the public one for a public folder. Something like this: namespace private { separator = / inbox = yes prefix = location = } namespace public { separator = / prefix = Public/ location = maildir:/var/mail/public } My plan is to eventually setup a public area for users to drop Spam and Ham into for my spam bayesan filter. The problem is the Wiki says if you drop a file in the public area called 'dovecot-shared' with the same permissions and ownership, that any new files dovecot creates there will use those same attributes. This does not seem to be the case. I created a Maildir folder identical to the one on the Wiki, named everything 'dovecot:dovecot' since my dovecot server will be running as that user, as well as the 'dovecot-shared' file. I get permission denied errors in syslog when I try to access it via an IMAP client. The only way I can make it work is ignore the dovecot-share file and put all users in a common unix group and make the Public folder group 'rwx'. Also, I would like to be able to make the Public folder writable, but not readable. It seems if I take the read bit away, my IMAP clients complain. Does anyone know how to make that work? One thing about the namespaces while I'm at it. I had to put my private namespace first followed by the public one. If I reversed them, all the subfolders except the inbox in my mail directories disappear from the client. Is that a bug too? Thanks, Adam

[Dovecot] Problems with Oulook Clients
by Patrick Carney 16 Mar '06

16 Mar '06

Hello all. I have problems with clients running Outlook 2003 that keep getting IMAP server timeout errors, "mailbox in an inconsistant state" Are there any mods to be made to the config file that could eliminate this? It happens about ever 10minutes. Here is what our previous Sys Admin sent me on our setup. dovecot is the IMAP server that allows clients to connect and get to their mailboxes. Postfix is that part of the mail system that moves messages around, from one server to another and puts them in the appropriate mailboxes. Thanks Patrick

The mailboxes I was using were directly copied from another server which was also using Dovecot. After I deleted all files named *dovecot* in the maildirs, the imap process no nolger crashes.

[Dovecot] migrating POP3 from UW IMAP: X-UIDL and X-UID
by Bertrand Leboeuf 15 Mar '06

15 Mar '06

With a INBOX mbox created by UW IMAP the messages in INBOX mbox contains the X-UIDL field When I use Dovecot POP3 with pop3_uidl_format = %08Xv%08Xu on the first run, X-UID is inserted, but all messages are downloaded again. What am I missing, I don't want the clients to download the read messages again. Thanks Bertrand Leboeuf leboeuf(a)emt.inrs.ca

[Dovecot] Imap crashes when trying to move messages
by ambroz.bizjak＠guest.arnes.si 15 Mar '06

The imap process crashes when SquirrelMail wants to move a message to another folder. I have run imap in gdb and talked to it the same way SquirrelMail does and got a backtrace. I am using Dovecot beta3. I am using it in combination with XMail, which has maildir databases. My system is Gentoo Linux on x86. The same version of Dovecot works great for me on amd64 with exactly the same config.

[Dovecot] Strange dovecot-uidlist behavior on maildir conversion
by allen petersen 15 Mar '06

15 Mar '06

Hi. So I just moved my email over from mbox to maildir. For the most part the conversion went fine, but I had a bit of an odd thing happen when I accessed my mail through dovecot. It seems that when I ran mb2md to convert my mailboxes from mbox to maildir, I got a lot of messages created that look like 1142356176.000000.mbox:2,RS 1142356176.000421.mbox:2,S 1142356176.000001.mbox:2,S 1142356176.000422.mbox:2,RS 1142356176.000002.mbox:2,RS 1142356176.000423.mbox:2,S 1142356176.000003.mbox:2,RS 1142356176.000424.mbox:2,S and so forth. Now, that really should be fine, that I can tell; each message has the same timestamp and a different, sequential delivery identifier. However, for some reason when dovecot accessed this directory, it created UIDs for these messages like so: (from dovecot-uidlist) 1 1142362834 915 1 1142356176.000488.mbox 2 1142356176.000207.mbox 3 1142356176.000425.mbox 4 1142356176.000117.mbox 5 1142356176.000398.mbox 6 1142356176.000335.mbox I have no idea where this order came from, but it's clearly not the order that I would have expected. I would expect that dovecot would sort these messages by timestamp, followed by delivery identifier. Instead, it put them in a seemingly random order. And, of course, my email client by default shows messages in the order that it gets them from the server, so now when I look at my email all of my old messages are shuffled until I do an explicit sort by date. Any idea why this is happening? Is there some reasoning behind this, or is it just a bug? I looked through the archives a bit, but didn't find a mention of anyone else with this particular problem. I suppose I could just create the initial uid lists by hand and put them in the correct order, but that really doesn't seem like the correct solution. Or I could actually dig through the source and find out exactly what it's doing, but, well, I figure that asking the list first is easier. For reference, I'm running dovecot 0.99.14-1 on debian sarge. I though that I was doing a good job by reproducing this on the newer version my ubuntu desktop, but it turns out that it's running the same version. :) -allen

[Dovecot] Rootless configuration
by James Davis 14 Mar '06

14 Mar '06

I'm trying to setup a rootless configuration so I can better manage the e-mail that comes to the mailbox of a unix account I have. I've successfully compiled Dovecot and followed the instructions for a rootless configuration, tweaking my config until Dovecot returns no errors. However I've got to a stage where upon running ~/..../sbin/dovecot it just quits with no server running and no errors. Any ideas? My rather small and basic configuration file is as follows... # Base directory where to store runtime data. base_dir = /home/jamesd/imap/dovecot/run/ # Protocols we want to be serving: protocols = imap listen = * ssl_disable = yes log_path = /home/jamesd/imap/dovecot/logs/ info_log_path = /home/jamesd/imap/dovecot/logs/ ## Login processes login_dir = /home/jamesd/imap/dovecot/run/login login_chroot = no login_user = jamesd ## IMAP specific settings protocol imap { listen = *:10143 } ## Authentication processes auth default { mechanisms = plain passdb passwd-file { args = /home/jamesd/imap/dovecot/etc/passwd } user = jamesd } Many thanks, James -- http://www.freecharity.org.uk/ - Free hosting for charities http://jamesd.ukgeeks.co.uk/
