[Dovecot] Upgrade from RC7 to RC10 didn't go too well...
by Dominic Lepiane 01 Nov '06

01 Nov '06

Hi, On the weekend I tried to upgrade from RC7 to RC10. Clearly, I have to change some things before I can do this. What does it take to get to RC10? As is, my mail client got an error trying to list messages in /INBOX (via IMAP) and the mail.err log shows the following messages: Oct 29 10:27:32 siona dovecot: IMAP(archangel): open(/var/mail/archangel/inbox, O_CREAT) failed: Not a directory Oct 29 10:27:32 siona dovecot: IMAP(archangel): mkdir_parents(/var/mail/archangel/.imap/INBOX) failed: Not a directory Oct 29 10:27:32 siona dovecot: IMAP(archangel): open() failed with subscription file /var/mail/archangel/.subscriptions: Not a directory My dovecot.conf includes default_mail_env = mbox:/var/mail/%u And other then enabling SSL, I've got a pretty vanilla configuration (e.g. nothing in the IMAP section at all, no odd namespaces...) /var/mail/archangel is an mbox file, why is dovecot trying to open files under there? I know at least part of the discussion has happened on the list before so I'm sorry for duplicating other questions. My TODO is about ten km long so I hope someone can at least give me a couple good pointers. Thanks in advance! -- Dominic Lepiane The IRMACS Centre

The NFS clients w/Dovecot are currently running Linux 2.6.16 with Trond Myklebust's Linux-2.6.16-NFS_ALL.dif applied (see http://client.linux-nfs.org/) This combo has been stable for months. And yes, we use fcntl locking, and mount noac,actimeo=0. JG

[Dovecot] moving public folders to private Trash
by Mark Nienberg 01 Nov '06

01 Nov '06

Using Thunderbird 1.5.0.4 against dovecot beta9: If a user has Thunderbird configured to move deleted messages into a Trash folder, then the user cannot delete folders in a public namespace. There is no problem deleting messages. Thunderbird says: "The current command did not succeed. The mail server responded: Can't rename mailbox to another storage type." All mailboxes (public and private) are maildir format. Users can successfully delete folders from their own private areas, and the folders then appear as subfolders of the Trash folder. Also, users can reconfigure Thunderbird to delete messages immediately instead of moving them to trash and then successfully remove public folders. Also, users can move public folders within the public namespace. So I think the problem boils down to the inability to move a folder from a public namespace to a private one, which is what happens when Thunderbird is configured to move deleted messages to a Trash folder.

[Dovecot] IMAP Dovecot with ISPConfig and shared folders?
by Perry 31 Oct '06

31 Oct '06

Fedora 5, postfix, dovecot, ISPConfig server all running well, (don't want to break it) LOL. But, I do not have IMAP shared folders. These instructions on dovecot tell of how to setup namespace to be able to get shared folders. http://wiki.dovecot.org/SharedFolders But given everything is relative in ISPConfig, not sure if this is possible or if I could really mess things up. What tells dovecot to look in the various different web# folders for email? Am I better off using Symlinking??? Thanks much for all comments and direction. ____________________________________________________________________________________ Cheap Talk? Check out Yahoo!

What have other people used? > Do we have other options? I recommend a pair of NetApp filers (e.g. 2 x 3020c) exporting NFS from shared disk shelves in their high-availability mode. This is a hybrid of the two options, except a) it's a fully supported and stable NetApp configuration, b) they're sharing disk storage, c) you're not hog-tied to GFS, d) it's the best NFS implementation in the world (you can even trust the fcntl locking), e) it's really fast, f) NetApp's onboard snapshots and other funky software bits will make you wonder how you lived without them, g) the HA actually works. I have a six-digit userbase with mailboxes in this configuration. JG

[Dovecot] auth both system and virtual users

[Dovecot] Problem report
by leslie.polzer＠gmx.net 31 Oct '06

31 Oct '06

Hello guys, Dovecot is a great IMAP server, I really like it :) I recently found an annoying problem, however: To sync my mail, I use OfflineIMAP, which usually works very smoothly. A spam mail with the year set to 2038 produced the error message "Invalid internal date" when OfflineIMAP tried to upload it to the server. Only deleting the messag helped. The usual data: Dovecot 0.99.14-1sarge0 on Debian Sarge x86. It would be nice to remove this date-smartness (?)... Kind regards, Leslie -- gpg --keyserver pgp.mit.edu --recv-keys DD4EBF83 http://nic-nac-project.de/~skypher/

[Dovecot] Continuing problems with zombied dovecot-auth procs; mail-cache-fields.c IMAP procs crashing
by JB Zimmerman 31 Oct '06

31 Oct '06

Folks- Hans Morten Kind was kind enough to confirm the issue I'm having with large mailboxes and the mail-cache-fields.c file (line 26: unreached error in logs when the imap process crashes out on large Maildirs). Has anyone implemented a fix for this that is both tested and applicable without making manual code changes myself, since I don't trust myself slashing about in source files? Ideally, has this problem been noted for fixing in a newer version? Failing that, if I downgrade to the 0.99 version shipped with RHEL4, has anyone found that to be more reliable? I used the 1.0rc10 in order to gain access to the 'namespace' conf directives so that upgrading from our current Courier Maildir installations would be as seamless as possible, but at the moment, I'm looking at having to roll back to Courier in order to fix this (and the next) problem. Also, we have found that using 1.0rc10 on RHEL4, using pam-ldap for account info and pam-krb for auth, has resulted in the eventual inaccessability of mail due to many zombied and unresponsive dovecot-auth processes. Restarting dovecot the first few times it becomes unresponsive will fix the problem, presumably by instantiating new auth procs, but eventually this no longer works since the restart doesn't actually kill off the zombied auth procs and the socket stops responding. Has anyone run into this problem? Thanks, J.B. Zimmerman RHEL4AS, fully updated, using the AT rpms: dovecot-1.0-0_27.rc10.el4.at --
