[Dovecot] Mailbox isn't a valid mbox file
by Jay Chandler 06 Apr '07

06 Apr '07

Keep getting this error within Squirrelmail (and other clients) on one particular user's mailbox file: ERROR: Could not complete request. Query: SELECT "INBOX.Backup" Reason Given: Mailbox isn't a valid mbox file I've snipped the first and last message off of it, still no love. mailserver# cat FILE | od -c | less 0000000 F r o m p r o m o t i o n s @ 0000020 e m e s s a g e . c i s c o . c So apparently there isn't a control character in the first message that'd be causing this either. Anyone have any ideas? Only one user out of many is having this issue, but he's whiny... -- Jay Chandler Network Administrator Chapman University

[Dovecot] Problems using GFS2 and clustered dovecot
by David Craigon 06 Apr '07

06 Apr '07

I am trying to use dovecot. I've got a GFS2 shared volume on two servers with dovecot running on both. On one server at a time, it works. The test I am trying is to attach two mail programs (MUA) via IMAPS (Thunderbird and Evolution as it happens). I've attached one mail program to each IMAPS server. I am trying to move emails around in one program (from folder to folder), and then checking it on the other program. I'm testing in effect how it would work if my users log on twice and end up on different servers. I seem to suffer from never ending index file corruption: Apr 4 16:55:49 mailstore-b dovecot: IMAP(david(a)everybody-loves.craigon.co.uk): Corrupted transaction log file /mnt/mailstore/e/everybody-loves.craigon.co.uk/d/david/.fish/dovecot.ind ex.log: end_offset (284) > current sync_offset (104) Apr 4 16:55:49 mailstore-b dovecot: IMAP(david(a)everybody-loves.craigon.co.uk): broken sync positions in index file /mnt/mailstore/e/everybody-loves.craigon.co.uk/d/david/.fish/dovecot.ind ex Apr 4 16:55:49 mailstore-b dovecot: IMAP(david(a)everybody-loves.craigon.co.uk): fscking index file /mnt/mailstore/e/everybody-loves.craigon.co.uk/d/david/.fish/dovecot.ind ex Apr 4 16:55:49 mailstore-b dovecot: IMAP(david(a)everybody-loves.craigon.co.uk): Fixed index file /mnt/mailstore/e/everybody-loves.craigon.co.uk/d/david/.fish/dovecot.ind ex: log file sync pos 1,284 -> 1, 104 Apr 4 16:55:50 mailstore-b dovecot: IMAP(david(a)everybody-loves.craigon.co.uk): Unexpected transaction log desync with index /mnt/mailstore/e/everybody-loves.craigon.co.uk/d/david/.fish/dovecot.ind ex Apr 4 16:56:18 mailstore-b dovecot: IMAP(david(a)everybody-loves.craigon.co.uk): Transaction log file /mnt/mailstore/e/everybody-loves.craigon.co.uk/d/david/.fish/dovecot.ind ex.log: marked corrupted This happens pretty quickly. I can also get message duplication- if I move a message from one server to another, I can get a message in the original folder and the destination folder. I am using RC28. I have tried using fcntl locking and dotlocking with equal lack of success. Can anyone offer any advice?

[Dovecot] managesieve proxy
by Marshal Newrock 06 Apr '07

06 Apr '07

We have dovecot on a pop/imap server working as a proxy to dovecot on the backend storage servers. This is working fine, but the difficulty is that if I use, for example, avelsieve in squirrelmail, it doesn't know where to connect. I imagine the same problem would exist with sieve-capable mail clients such as KMail, especially since the outside world isn't allowed to connect directly to the storage servers. Does anyone know of a way to proxy managesieve? -- Marshal Newrock Ideal Solution, LLC - http://www.idealso.com

[Dovecot] truncated maildir root?
by Joe Wong 06 Apr '07

06 Apr '07

Hello, I have successfully configure dovecot to lookup my existing user database to lookup the homedir. However, I found the following from the log: dovecot: Apr 05 04:05:16 Info: IMAP(joewong99:tkodog.no-ip.com): Effective uid=1001, gid=1001, home=/mnt/mailmountpoint/4/22/3/joewong99:tkodog.no-ip.com@tkodog_no-ip_com dovecot: Apr 05 04:05:16 Info: IMAP(joewong99:tkodog.no-ip.com): maildir: data=/mnt/mailmountpoint/4/22/3/joewong99:tkodog.no-ip.com@tkodog_no-ip_com/Maildir dovecot: Apr 05 04:05:16 Info: IMAP(joewong99:tkodog.no-ip.com): maildir: root=/mnt/mailmountpoint/4/22/3/joewong99, index=/mnt/mailmountpoint/4/22/3/joewong99, control=, inbox= The "root" is truncated after the colon. Can I configure dovecot not to do it? I have 10000 messages in /mnt/mailmountpoint/4/22/3/joewong99:tkodog.no-ip.com@tkodog_no-ip_com/Maildir but SELECT INBOX show no messages. Regards, - Joe

[Dovecot] GSS/Kerb5, Solaris 10, how to build?
by Jeff A. Earickson 06 Apr '07

06 Apr '07

Gang, I've been trying to build rc29 under Solaris 10 using either "--with-gssapi" or Kerberos 5 ticket usage. I'm trying to figure out how to set up fetchmail on another S10 box to do IMAP fetches from dovecot without having to enter a password. No matter what configure option I try, I get Building with GSSAPI support ........ : no at the end of the configure. I searched the list archives and I see some discussion from Dan Price about Solaris 11 builds. Is gssapi supposed to work with Solaris 10? Advice please? My dovecot server is a Kerberos 5 client of Active Directory, with PAM configured to do TGT exchanges. I can login to the system with my AD password, ssh to other Kerb clients without having to type in passwords -- Kerberos works at the OS level. Jeff Earickson Colby College

[Dovecot] changing fs separator for maildir (suggestions?)
by Justin McAleer 05 Apr '07

05 Apr '07

Since we're migrating from an existing system that allows periods in folder names, I believe we must continue to allow them. So, I am deciding what to use as the separator instead. Right now, I'm leaning towards the backtick (`), since I don't think I have ever used it unless I was trying to execute an external command in some code. So, can anybody think of reasons not to use it, or have a better idea?

Re: [Dovecot] Problems using GFS2 and clustered dovecot
by David Craigon 05 Apr '07

05 Apr '07

Well, I'm not paying for it. And I've managed to fix the comedy stability I've come across so far, but you're right- I haven't really loaded the system up yet. My rationale is that I want a filesystem I can share between several servers, reducing the points of failure as far as I can down. We've got a large iSCSI SAN we've already bought for other projects, and I'd like to use that for our storage. So using NFS, I'd have to have another server in front of my SAN that act as an NFS server (presuambly as a single point of failuire), and the mail servers as NFS clients. I'd rather have the servers talk to the SAN directly. Besides, NFS never really works for me, but I'm sure I could overcome that. Anyway, I don't think it's a GFS problem so far.

Sorry, it's just struck me that I've missed out the most important information- I am using maildir++. Sorry :-(. The index files are kept on the shared volume. And to answer the other question again, mmap is off.
