I am trying to monitor with Nagios that my phones are consistently checking into dovecot via IMAP. I used to be able to parse syslog for imap-login messages. I have since updated my phones, the phoness email client (k9-mail) and dovecot. Now the imap-login messages are few and far between. However, I can clearly see via tcpdump that some traffic is happening when I click refresh on k9. I enabled "rawlog" support in dovecot, but it doesn't seem to write to disc frequently enough. 1) Does anyone have a better suggestion for how to monitor that my phone is checking in regularly? 2) Is there a flush-to-disk capability for rawlog in dovecot? 3) Also, when you have imap_zlib plugin enabled, the rawlog logs the raw compressed data instead of the decompressed IMAP commands. Is this an oversight? (FYI: k9 is calling SELECT "INBOX" on refresh) Thanks, G H

Question About Dovadm syntax
by Kenneth Ulrich 06 Apr '15

06 Apr '15

Hello All, I just have a quick question about doveadm commands. 1. Is there a command that we can use to count emails for a particular end user? 2. If an end user needed to copy/move emails from one account to another, is there a command? Also, I've searched Google results, numerous Ubuntu, CentOS, Fedora forums, Doveadm forums, and read the DoveCot/DoveADM man pages numerous times and either I am over looking, or I am not understanding. Thus why I am asking here.

speaking of sieve scripts... how to selectively not send vacation autoreply
by Harondel J. Sibble 04 Apr '15

04 Apr '15

Don't need to block anyone like in the "Re: Dovecot Oy merger with Open-Xchange AG" thread, but when I have my vacation recipie active, I'd like it to NOT reply to certain addresses. I tried the following, you can see the section with if header :contains "addressIdontwant(a)repliedtoo.tld" is commented out, once I'd added that section, no Vacation messages went out at all. Googling and reading the wiki and recipie suggestions doesn't make it clear how to exempt a list of addresses from ever receiving a vacation response. Suggestions on additional reading or solutions? require ["fileinto", "vacation"]; if header :comparator "i;ascii-casemap" :contains "Subject" "**SPAM**" { fileinto "Trash"; stop; } #if header :contains "addressIdontwant(a)repliedtoo.tld" { # stop; #} vacation # Reply at most once a day to a same sender :days 1 :subject "Changes to email addresses effective Jan 01/15" # List of recipient addresses which are included in the auto replying. # If a mail's recipient is not on this list, no vacation reply is sent for it. :addresses ["user(a)repliedtoo.tld"] This is on a Dovecot 1.x system that is slated for an upgrade soon. -- Harondel J.

Dovecot Oy merger with Open-Xchange AG
by Timo Sirainen 03 Apr '15

03 Apr '15

Hi all, Today I can finally announce that Dovecot Oy company has merged with Open-Xchange AG. This helps us to get more Dovecot developers, support people and so on. Most importantly, eventually it should allow me to get back to doing what I like the most: Designing new and interesting stuff for Dovecot and perfecting the old stuff :) OX is a great match to Dovecot going forward. They also really like open source and share our plans for the future. Nothing big will change as a result of this merger: Dovecot will stay Dovecot with its own name and release schedules. We're not going to force OX and Dovecot to be the same product, other than having a somewhat deeper integration between them. Here are the press release links about it: http://www.dovecot.fi/open-xchange-and-dovecot-announce-merger-to-create-wo… http://www.open-xchange.com/dovecot http://www.open-xchange.com/announcements/18

EL6 EE package dependencies
by Will Yardley 03 Apr '15

03 Apr '15

I've been trying to upgrade Dovecot-ee package (on EL6/x86_64) from 2.2.15.8-1 to 2.2.16.2-1. It's complaining on these two dependencies: liblz4.so.1 libtextcat.so.0 These would both seem to be related to plugins, and don't seem to be required as package dependencies by the RPM from what I can see from the SRPM. Anyone know what packages I need to satisfy these dependencies?

Install process breaks its self by design
by Merlin at Desktop Masters 02 Apr '15

02 Apr '15

Greetings, I just tried to install Dovecot for the first time. It was on a virgin Ubuntu/Debian server (Version: 1:2.2.9-1ubuntu5) and the install failed. After a bit of struggling I worked out that the install fails BY DESIGN. Spoke about this with a few people and we decided it was best to report this issue and request that you redesign the packing so it does not fail. The reason it fails is as follows... When you install it asks you if you want to use self signed certificates. I have certificates so I said, "No". At the end of the install the script tries to start dovecot. It cannot because the service does not have certificates so it fails. This causes the script to abort and the other packages not to install and breaks the install process. I had to purge dovecot, then install it with the self signed certificates. So we have 2 issues here. 1. Why allow people to not install certificates if it is just going to break the install and confuse them. 2. Why are you starting the service right after install when dovecot clearly requires manual configuration as part of the setup. I recommend you resolve this by NOT starting the service as part of the install unless it is an upgrade and the service was already running. ~ Merlin

Correct Correct Correct And when I went to the page it lead me here. Whomever is making the .deb packages needs to be made aware of this. Can you please point me into a direction? ~ Merlin On 4/1/2015 4:33 PM, edgar(a)pettijohn-web.com wrote: > On 2015-03-29 13:58, Merlin at Desktop Masters wrote: >> Greetings, >> >> I just tried to install Dovecot for the first time.

Migrating from Cyrus to Dovecot
by Miloslav Hůla 31 Mar '15

31 Mar '15

Hi, we are migrating from Cyrus 2.3.7 to Dovecot 2.2.13. We have ~7000 maildirs with ~500GB. Our goal is to do the migration without users have notice and with the shortest service downtime. The users use IMAP (with shared folders and ACL), POP3 and sieve filters. As a first choice, we tried the Dovecot's dsync tool. First tests were great, but we are not able to change the Cyrus auth backend for migration. Moreover, this migration seems too slow for us. As a second try, we tried the cyrus2dovecot migrating Perl scripts (and their derivates) from Wiki2. More or less they works but we found we need more control during the migration. So, as a third try, we wrote own migrating scripts. And thanks to the cyrus2dovecot it wasn't too much complicated. And there are my questions: A) Files and dirs timestamps The mtime of email file is important as an internal date as I found on Wiki2. But what about timestamps of cur/new/tmp directories or Dovecot's internal files line dovecot-uidlist? Do they play some role here? B) The 128 bit mailbox UID The Wiki2 speaks about 128 bit mailbox UID at first line of dovecot-uidlist. Cyrus preserves only 64 bit UID. Is this mailbox UID required by Dovecot? If so, can we use 0000000000000000501100008c4a11c1 (Cyrus UID padded by zeros)? C) Format of dovecot-uidlist records Wiki2 shows two examples: 25006 :1276528487.M364837P9451.kurkku,S=1355,W=1394:2, 25017 W2481 :1276533073.M242911P3632.kurkku:2,F Which format is preferred? Or what the benefits are? D) Converting between CRLF and LF If I understand correctly, Dovecot stores emails with LF only. We have all emails with CRLF now on Cyrus and converting them to LF only is a little more time consuming. Is there any benefit to do that? Or can we live with 'mail_save_crlf' without problems? E) POP3 backend I found many informations about IMAP internals but few on POP3 internals. What do I need to do POP3 migration transparent for user? Many thanks for any answers. Regards, Milo
