similar to: Maildir feature I'd like to see - SSD for newer messages

I just replaced my drives for Dovecot using Maildir format with a pair of Solid State Drives (SSD) in a raid 0 configuration. It's really really fast. Kind of expensive but it's like getting 20x the speed for 20x the price. I think the big gain is in the 0 seek time. Here's what I bought. Crucial RealSSD C300 CTFDDAC256MAG-1G1 2.5" 256GB SATA III MLC Internal Solid State

I'm advocating for a change in the IMAP specification to allow outgoing email to be sent over the same connection as incoming rather that having to separately configure outgoing SMTP email. There are two significant advantages to this concept. 1) It would greatly simplify setup for clients as they would only have to configure one connection rather than two. 2) Spam reduction by

I recently upgraded dovecot from 1.0.15 to 1.1.2 and since then I am getting the following types of things in the logs: Aug 21 17:23:13 mail1 dovecot: imap-login: Login: user=<myuser>, method=PLAIN, rip=172.16.78.20, lip=172.16.78.22 Aug 21 17:24:01 mail1 dovecot: Panic: IMAP(myuser): file index-sync.c: line 39 (index_mailbox_set_recent_uid): assertion failed:

I just installed a limited test of RC10 last night. So far, all is great except for errors being logged for one user (out of about 150 users total). This one user has not yet complained or anything, but the log file has repeated entries of the following format for him (host and username changed to protect the guilty/innocent): Oct 24 06:13:02 mail dovecot: IMAP(username): file

Here's some thoughts I'd like to throw out there. I know it's not standard IMAP protocol but someone has to try new ideas first and I want to see what people (Timo) think of this. IMAP establishes a connection between the client and the server. Wouldn't it be great if it could be a conduit to let custom Thunderbird plugins talk to custom server application over the IMAP

Here's what I'd like. Limited master users, where someone can be a master users for some domains but not others. I think I could do what I want with the right kinds of variable passing that doesn't yet exist. Let me see if I can explain clearly. From the example in the wiki: auth_master_user_separator = * passdb { driver = sql args = /etc/dovecot/dovecot-sql-master.conf.ext

Hi, This small mail to share my observation about a recent move of mailboxes between two servers and ask about explanation and/or improvement about UIDL in dovecot. SV1 : Dovecot 0.99.14 / Red Hat Fedore Core 4 SV2 : Dovecot 1.07 / CentOS 5.2 Mailboxes in /var/spool/mail on the twoo servers. Test will be done with outlook express with option "leave message on server" checked. Goal is

OK - I thought this was going to be easy. Maybe it is. I'm just not that good at reading directions. Trying to use dsync. Getting this error: Mail locations must use the same virtual mailbox hierarchy separator (specify separator for the default namespace) Currently using maildir. The setup is as follows: mail_uid = mail mail_gid = mail mail_location =

And it's taking up more space on the 4T drive. What did I miss?

Is it possible to have some folders be mbox and some be maildir format? Why you might ask? Sometime for diagnostics I have the Exim MTA archive certain messages in MBOX format and then I want to copy them into an imao folder to look at them with Thunderbird. When I used MBOX all I had to do was copy the file into a folder and it worked. So what I'd like to do is have a folder with a

Hi Folks, How scalable is dovecot. Do you think a machine with a dual core 2.8Ghz processor and 2GB of RAM would do a business with 600 users? This server will have a 100Mbps link to the net, however it will be access by the business using a couple of ADSL lines (Roughly 7Mbps each). This machine will also be running Postfix Your help is appreciated Cheers Jonny

Hi everyone! What's the best filesystem to use for the mail spool? I'm debating between Debian with xfs or FreeBSD with zfs. I'm not sure which way to go. I'm migrating from cyrus. I have about 50 users so it's not a large setup. Cheers! Monika -- Monika Janek Systems Administrator, Side Effects Software Toronto, Ontario Canada 416-504-9876 x207 www.sidefx.com

I am migrating from UW to dovecot and using mbox. I have been able to find mbox to maildir migration information and tools; however, I have had little luck finding any tool or information for performing such a migration where I wish to keep mbox. ( I know I should migrate to MailDir, but in the case I wish to take baby steps.) I have setup dovecot pop3 communication and I go to my email client

Hi! I'm currently running Dovecot 1.1.8 on a HP server using CentOS 5.2 as my IMAP server, receiving mail from postfix, and also using squirrelmail as the frontend. As I look at upgrading the mail server, I'd like to change to a higher availability configuration (where the server can fail and I don't have to reconfig my imap users). For the SMTP that's easy, because I can

GlusterFs always strikes me as being "the solution" (one day...). It's had a lot of growing pains, but there have been a few on the list had success using it already. Given some time has gone by since I last asked - has anyone got any more recent experience with it and how has it worked out with particular emphasis on Dovecot maildir storage? How has version 3 worked out for

I have very strange problem with masteruser. See two logs below: # telnet localhost 143 Trying 127.0.0.1... Connected to localhost.

Hello, I want to setup dovecot with two postfix servers on three machines: - dovecot - with huge amount of disk space - where all user emails will be kept, - postfix1 - with greylisting, amavisd-new (spamassassin, clamav, etc), with mysql backend, - postfix2 - same as postfix1. MX priority will be set to the same value for both postfix machines. For now I don't know how to "glue"

Hi -- Today, I've learned who to disable incoming mail delivery to dovecot (accepted by postfix), temporarily. Now, I would like to know if there is a way to make a "doveadm kick -A" a permanent disconnect until one would allow reconnects, again? This should be done *without* shutting down dovecot or *extensive* re-configuration. A "doveadm block -u <joe> -m 'sorry:

Hello We are using dovecot 1.2.x. In our setup we will have 1200 concurrent imap users (maildirs) and we have 2xraid5 sas 15k diks mounted by iSCSI. The dovecot server (RHEL 5 x64) is a virtual machine in our vmware esx cluster. We want to minimize disk I/O, what config options should we use. We can "exchange" CPU & RAM to minimize disk i/o. Should we change to dovecot 2.0?

Here's what I'm trying to do. I have a spam filtering operation as a front end for other servers. I've created a virtual server for spam storage where the user will be able to log in using squirrelmail/dovecot to review and release their spam. The email is stored in maildir format. Piecing it together I can use squirrelmail to pipe the email into something so that if a use finds a
