[Dovecot] iterate_query not working
by Piotr NetExpert 04 Nov '11

04 Nov '11

Hi, I have got iterate_query defined in dovecot-sql.conf.ext. However when I run a command like: doveadm search -A BEFORE 10d I receive an error message (Failed to iterate ...) There is an error message in a log file too: Error: Trying to iterate users, but userdbs don't support it The problem is that monitoring a database server shows that dovecot does not try to execute any query. What I am doing wrong? password_query lookups work fine. -- pozdrawiam Piotr Szafarczyk http://www.netexpert.pl

[Dovecot] Getting the SMTP envelope through IMAP?
by Hadmut Danisch 04 Nov '11

04 Nov '11

Hi, just a simple question about dovecot: The mbox file format contains the SMTP envelope sender and transmission date in a FROM ... line preceding the RFC822 mail header and body. As far as I see at the moment, the IMAP protocol does not support transmission of that SMTP envelope data in either way, but confusingly uses the term „envelope” for a structure describing the RFC822 mail header. My question is, whether there is any way to retrieve the SMTP envelope through dovecot's IMAP anyway, maybe through some extension. regards Hadmut

Hi there, there is the ubuntu version 2.0.13 ov dovecot installed on our server. But in contrast to http://wiki2.dovecot.org/Tools/Doveadm/Altmove the option -r isn't supported in this version. altmove: invalid option -- 'r' doveadm altmove [-u <user>|-A] [-S <socket_path>] <search query> In which version of dovecot is this option supported? Thanks Lars

We follow the guidelines about timekeeping RHEL in vmware vsphere located here http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=di… These problems happens in peak hours. Any dovecot config parameter I could set to mitigate this problem?

Something to do with it rescheduling machines and them not counting idle ticks or something..? Does this problem happen during idle hours or peak hours? I should home in on clock problems... Probably vmware related issues to the kernel you are using? Good luck Ed W

[Dovecot] How can we horizontally scale Dovecot across multiple servers?
by Arlin 04 Nov '11

04 Nov '11

Hi, How can we horizontally scale Dovecot across multiple servers? Do we require to install independent instances of Dovecot on each server? We are planning to use a NAS/SAN device using ZFS or EFS for email storage. Each logical unit will be of 10TB and similarly as the no: of user increases we are planning to add multiple 10TB units. In this case how we can manage the email storage on multiple volumes from Dovecot. The configuration of our existing system is:- Dovecot 1.0.15 / Maildirs Postfix 2.5.5 Debian 5.0.9 (Lenny) MySQL 5.0.15 Please advise. Thanks in advance. Creative Regards, Arlin

[Dovecot] looking for Dovecot-code + SQL consultants
by Rich 03 Nov '11

03 Nov '11

Hi, We're using Dovecot2. Trying, given our own spread-too-thin bandwidth, to make it work within our evolving SQL application environment. When there's a problem, we post to this list (e.g., http://www.dovecot.org/list/dovecot/2011-October/061609.html) but aren't getting any/timely responses. We've decided to look for a consultant (hourly or retainer) that can be available for working with our in-house staff to straighten these issues out -- by helping us identify & fix our own mess, and by working to get fixes pushed to Dovecot project code, where appropriate. If you provide these services, rather than simply deployment or hosting, and are available, please drop me a line *offlist*. We're in the San Francisco area, and local is best, but remote work is certainly an option. Thanks, Rich

All the ESXs hosts and all the VM use the same NTP server. Any other idea? Regards Maria ----- Original Message ----- From: Giulio Casella Sent: 11/03/11 11:38 AM To: dovecot(a)dovecot.org Subject: Re: [Dovecot] Dot Lock timestmap, users disconnections from roundcube This could be the problem. Double check the time also on your host system(s), not only on guest. Bye, gc Il 03/11/2011 11.30, Maria Arrea ha scritto: > We use ntpd daemon, all our systems are configured equal.

We use NTP. Quick check, but by "NTP" you mean the background daemon and you don't have some cron job running ntpdate or similar every so often? No idea, but since it looks like a clock related curiousity, then knowing if the clock is spot on accurate or drifting would be interesting to know? Simple comparison against other machines over a similar period to you having problems might be accurate enough?
