[Dovecot] High load/corrupted indexes after moving mailboxes?
by Patrick A. Treptau 12 Mar '09

12 Mar '09

Hello, we're experiencing an odd issue after combining two vDisks used for mail storage into one big new LVM. We've done this in the past successfully and didn't experience a lot of problems. We stopped all services (dovecot/postfix) to ensure that mailbox contents (Maildir) will not be changed, rsynch'ed the mail to the new disks and restarted everything. When we restarted dovecot, we noticed a huge spike in load (average load in top and high cpu iowait) and isolated dovecot as the issue. At some point, the average load crept up to over 100 and crashed the server twice. However, over time the average load and cpu wait times went down slightly. I have noticed a spike in load after moving user's mail storage, but not like this. It almost looks like everyone is either re-indexing or re-caching their mail? Any help would be appreciated. We're on dovecot 0.99. -Pat

[Dovecot] migration from dovecot to dovecot on different servers without downtime (dovecot replication?)
by Pau Oliva 12 Mar '09

12 Mar '09

Hello, I have an imap server with huge Maildirs and several users running dovecot 1.0.13, I need to migrate all the imap accounts to a new box which runs dovecot 1.1.4. The requisite is that need to do it with no downtime or minimal downtime possible, and totally transparent for end users. I have tried IMAP<-->IMAP syncing using a master user in both servers and imapsync, however due to the huge Maildirs (some users have more than 10 years of mail) this tends to be quite slow and painful. Can I tar all the user's Maildir and move them from one box to the other, and then run imapsync again? which I assume that would be faster... or is there any better solution I am not aware of? (ie: I've seen some emails about dovecot replication on the list archives, but few details of how that should be configured). I'd appreciate any feedback or thoughts on this matter. Thank you. Cheers, Pau Oliva

[Dovecot] GUI/WUI for creating (common) sieve scripts?
by Roderick A. Anderson 11 Mar '09

11 Mar '09

Anyone aware of a Web User Interface or GUI to allow users to create simple/common-type sieve scripts? I found the sieve testing and have used it as I play; plus mangesieve (and Net:ManageSieve.pm) but want to allow users to build so some clicking and maybe a little typing and then end up with some filters. So before I go invent this wheel I'd like to know what others are doing? TIA, Rod --

[Dovecot] dbox on CIFS
by Daniel L. Miller 11 Mar '09

11 Mar '09

Ok - at this time I am using the following non-default settings: Samba server - smb.conf [Mailstorage] ea support = Yes use sendfile = Yes fake oplocks = Yes delete readonly = Yes Dovecot - dovecot.conf mmap_disable = yes dotlock_use_excl = yes fsync_disable = yes lock_method = dotlock I'm still testing - but at this time I'm seeing no errors. Two options I can state cause severe problems are the "directio" and "setuids" mount options for the cifs client. -- Daniel

[Dovecot] [Fwd: Re: [vchkpw] vpopmail now has vusage daemon support]
by Rick Romero 10 Mar '09

Is the index modification code portable that other software could link to a Dovecot library and update indexes on delivery? <snip from vpopmail list> Rick Romero wrote: > I was considering changing vdelivermail to have a stdout option, where > you could pipe from vdelivermail to Dovecot's deliver for 'final' > delivery instead of direct to Maildir within your .qmail-default file. > That 'should' allow everything else to occur normally, but get those > indexes updated as well. I think just 'HOME' needs to be exported, > but I haven't tested it yet. Is there a way to update Dovecot's indexes without having it handle delivery? In that case, we could easily add support for this into vpopmail. - -- /* Matt Brookings <matt(a)inter7.com> GnuPG Key D9414F70 Software developer Systems technician Inter7 Internet Technologies, Inc.

[Dovecot] Error crosscompiling
by Diego Roversi 10 Mar '09

10 Mar '09

Hi, I was trying to crosscompile dovecot, but I got some error: --with-notify=inotify don't work, as it try to run a test program to verify if inotify is supported in the building platform. Solved with --with-notify=dnotify. Ihmo, is more a hack than a solution. | checking whether posix_fallocate() works... configure: error: cannot run test program while cross compiling I can't find an a suitable option for this error. Again the problem is that configure can't run an executable for a different platform. It's possible to set a safe default? Thanks in advance. -- Saluti / Regards Diego Roversi | | diegor at tiscalinet.it
