[Dovecot] Regarding dovecot-antispam bug!
by Mikael Jenkler 21 Aug '08

21 Aug '08

Hi All! There is a issue with dovecot-antispam and the new dovecot-1.1.x (dovecot-1.1.1) The imap server dies when sending mail, the mail goes away but it says that the imap server has crached in squirrelmail. I get the standard signal 11 crach in the dovecot loggs another question? My dspam users has the email as username somthing(a)domain.com and in dovecot.conf i need to specify the user when training, is there a w way to get the resiptient address in the dovecot.conf? i am only able to get %u ie the username ;-( Could you patch the antispam plugin to be able to take then resiptient as dspam user? ie the mail address , you can have a option in dovecot that says use resiptient address as user or something it would be great if you had time to check this out ;-) Thanks in advance

[Dovecot] Sent Date/time vs Received Date/time

I know that every message has a 'received' header, which is basically the date/time stamp of the SENDERS CLIENT - so if their system's time is off, that date/time header will be off. So, where does this 'Order Received' column in TBird get its info from? I'm guessing it is a TBird thing, like an internal index number? In my mind, there should be two primary date/time columns: Sent Date/Time = Date/time of the Client system when message was sent (this is already there as the plain 'Date' column) and Received Date/Time = Date/time the receiving SERVER DELIVERED it I can see the benefit for the third 'Client' side Date/time stamp, which is the current 'Order Received' in TBird. I'd like to see support added for grabbing the last date/time from the LDA that delivers the message, but that obviously request is for the TBird devs (or most likely an extension request), but... The main question is - is there a proper IMAP/RFC for providing/getting this date/time? -- Best regards, Charles

> I suppose the OP does not sort by date but Arrival time (this means arrival time in the mailbox). Exactly. I sort by arrival time, which in practice is the "unsorted" ordering based upon the mbox file itself. (Except I'd like to control the arbitrary "unsorted" order that I want by "resave to inbox" to handle reordering.)

Does anybody know why this code was designed this way / why it is different from 0.99 behavior / etc?

[Dovecot] Dovecot & (Al)pine - resaving messages to Inbox
by Jonathan Herbach 21 Aug '08

21 Aug '08

I have a x86 Linux box running Fedora 4. Up until 2008 I was using pine 4.64 and Dovecot 0.99.x. In early 2008 I transitioned to Alpine 1.10, and didn't notice any major changes. I upgraded to Dovecot 1.0.15 this past weekend. My dovecot -n settings are at the bottom of the email. I've noticed a change since Dovecot was upgraded. I used to reorder items within my INBOX in al/pine by "saving" messages back to the INBOX, which I was connecting via IMAP . Now when I try to do it I get an error in alpine that says: [Can't copy mails inside same folder] then: [Save to folder "{localhost:143/i...r=jherbach}INBOX" FAILED] While these are alpine messages, they appear to be from the dovecot upgrade. I really miss the ability to reorder messages in my inbox since I often use it as a queue of important items. Does anybody have any ideas why I'm seeing this error message? Or better yet, how to potentially (re) configure the system to allow me to resave messages into the same folder?

[Dovecot] config file parsing, tab characters
by John Hannfield 21 Aug '08

21 Aug '08

Hello, I am using the latest dovecot 1.1.2 with postfix, and using doveco deliver command for LDA. I really love dovecot, and how it has progressed over the years. However I have noticed that if I put a TAB character in the dovecot.conf file, it sometimes does not parse the file correctlty, and complains about missing postmaster_address etc, even though they are there. So I reformated my config file, with just spaces, no tabs. I am very careful about that now. However I still seem to have a problem in some places with spaces. For example, in the LDA section: If I have 3 or 4 spaces, after the lda line in the definition, like so: #----------------------------------------------------------------------------- # LDA Settings #----------------------------------------------------------------------------- protocol lda { postmaster_address = postmaster(a)mydomain.com hostname = mydomain.com .... it does not work. I must have only 1 space between the end of lda and the curly bracket. Like this: #----------------------------------------------------------------------------- # LDA Settings #----------------------------------------------------------------------------- protocol lda { postmaster_address = postmaster(a)mydomain.com hostname = mydomain.com .... This seems very flaky. I am not certain I will always be able to check the file when making changes. So my question is: 1. Is there someway to check the validity of the dovecot.conf file. I notice dovecot -n does not print the entire config. 2. Is there any chance the code used to parse the config file, could be updated to be more robust, and to include support for tabs? Thank you. Paul

[Dovecot] How Can I Tell How Dovecot Was Installed?
by Blake Carver 21 Aug '08

21 Aug '08

I'm trying to help someone with Dovecot, and it looks like this one is a few versions behind. They say that they're not sure if it was installed Via an RPM or a source tarball. Dovecot is use MySQL. This is a RHEL5 server. There are RPMs listed as installed (rpm -qa) but I don't know how I can tell what was used to install the currently used set up. (also asking on the Postifix list) Is there something in a conf file or something that shows me how it was installed? Thanks Blake

[Dovecot] Stateful Webmail
by Michael Carter 20 Aug '08

20 Aug '08

Hello, I'm a developer on the Orbited project (http://www.orbited.org) which provides a TCPSocket interface in javascript (emulated over HTTP using ajax and comet.) This TCPSocket allows true bi-directional communication between a web browser and an arbitrary tcp server. One of the other developers pointed me to a recent dovecot thread about webmail. Sorry for the new thread (I just joined this list and couldn't reply to the old emails). Timo Sirainen wrote Wed Aug 13 23:37:11 EEST 2008: > I wrote this a while ago: http://imapwiki.org/ClientImplementation > > One thing that would be nice, that pretty much no webmail does, is to > keep a stateful connection open all the time (or at least some of the > time) instead of creating tons of short-lived connections that ask the > same stuff over and over again. With a stateful connection you could > basically run IDLE and wait for changes there instead of asking all > the time "is there new mail?" "is there new mail now?" "what about > now?". Coincidentally, we have just began work on a JavaScript IMAP client. With it, building a webmail app should be *entirely* a UI concern. The good news is that our Socket interface is very stable and is being used in production for protocols like IRC for webchat. The bad news is that none of the the Orbited developers have experience with the IMAP protocol. We are putting all of our protocol implementations in the soon-to-launch js.io project (www.js.io) As soon as we have any kind of IMAP client prototype, I'll let you know. In the meantime, would anyone be interesting in helping us develop the imap client? Its 100% pure JavaScript, and will greatly ease the development of feature-rich webmail, as a webmail deployment will become a matter of simply running Dovecot, the js.io.imap client, and an HTML gui. -Michael Carter

[Dovecot] dovecot performance
by Giorgenes Gelatti 20 Aug '08

20 Aug '08

Hello All, I've been studying dovecot for replacing my company's current system and I got a little worried about an aspect of the dovecot's design. I was surprised that dovecot doesn't use prefork for its mail processes, forking a new processes for each new client connection. Talking in the #dovecot channel I was gave a scenario of a system supporting ~40k users with 4 servers just fine. I wonder how well dovecot would scale if we increase this number of users by some order of magnitude like, say, 4M users. It is well known that preforking is a good pratice if you want to achieve a higher performance. When I was asked about it I readily answered: "of course it does". For my surprise later, i doesn't. Do you have any plans to support preforking in the near future? Best regards, giorgenes

[Dovecot] dovecot: Fatal: Time just moved backwards by 3603 seconds.
by Stephen Feyrer 19 Aug '08

19 Aug '08

<nervous_darting_eyes> Hi Everyone. </nervous_darting_eyes> Ooops I just broke my dovecot install. I've looked through the mailing list archives and not found anything relevant. When I try to connect to my mail server I get this message. "Could not connect to mail server chen.home.org; connection was refused" The last message in /var/log/mail.err is:- Aug 13 21:02:27 chen dovecot: Fatal: Time just moved backwards by 3603 seconds. This might cause a lot of problems, so I'll just kill myself now. http://wiki.dovecot.org/TimeMovedBackwards It seems this is my own fault. Time on my system is a little wonky so I reset the time and then I found out I'd broken Dovecot. I didn't realise that doing this would have an impact on dovecot. I read the web page and to be honest I'm not confident about hacking source code. I've reinstalled dovecot which worked except it hasn't solved my time travel problem. By the way since my first install of dovecot the config file seems to have changed a little but since I've tried to migrate my settings over the new file and been met with the same problem I don't think it's that. Is it possible to get dovecot working again? -- Regards Stephen.

Anyone using the mobile IMAP option on the LG Voyager (mobile phone) with dovecot? I think it costs $5 extra per month. Seems low enough just to try it and find out. Thanks

[Dovecot] SpamAssassin and Maildir with Dovecot
by Kenneth Porter 19 Aug '08

19 Aug '08

A patch has been proposed for SpamAssassin to process Maildir folders of spam: <https://issues.apache.org/SpamAssassin/show_bug.cgi?id=3003> Is this patch compatible with Dovecot's implementation of Maildir? For example, is anything needed to avoid stepping on Dovecot's metadata?

[Dovecot] POP3 dictionary attacks
by Kenneth Porter 18 Aug '08

18 Aug '08

I'm seeing strings of failed POP3 login attempts with obvious bogus usernames coming from different IP addresses. Today's originated from 216.31.146.19 (which resolves to neovisionlabs.com) This looks like a botnet attack. I got a similar probe a couple days ago. Is anyone else seeing these? The attack involves trying about 20 different names, about 3-4 seconds apart. Here's a few sample log lines: dovecot: Aug 15 04:15:45 Error: auth-worker(default): pam(mike,216.31.146.19): pam_authenticate() failed: User not known to the underlying authentication module dovecot: Aug 15 04:15:49 Error: auth-worker(default): pam(alan,216.31.146.19): pam_authenticate() failed: User not known to the underlying authentication module dovecot: Aug 15 04:15:53 Error: auth-worker(default): pam(info,216.31.146.19): pam_authenticate() failed: User not known to the underlying authentication module dovecot: Aug 15 04:15:57 Error: auth-worker(default): pam(shop,216.31.146.19): pam_authenticate() failed: User not known to the underlying authentication module Timo, can you add the port used in the attempt to the error log entry? (It does show up in the info log entry, but that means I need to correlate lines in the two log files.)

[Dovecot] IMAP maildir performance difference between dovecot-uidlist versions?
by Jack Stewart 17 Aug '08

17 Aug '08

Hi, Is there an IMAP performance difference using Maildir between using version 3 and version 1 of the dovecot-uidlist (either dovecot 1.0.7 or 1.1.2)? It isn't entirely clear to me there is any difference as the filename may contain the size/vsize information. The servers will eventually be running 1.1.2 with the maildir_copy_preserve_filename turned on. I'm doing a batch migration from courier to dovecot 1.0.7 and eventually dovecot 1.1.2. These servers are, and will continue to be, IMAP only (i.e. dedicated control/dovecot-uidlist files). The migration script is run once - no build on the fly. It does a readdir() to get the full filenames and make sure that list entries are only for existing files. As a result, there is almost complete freedom in the output format for the dovecot-uidlist. Many thanks in advance! ---Jack P.S. For better or worse, it does seem that once you are stuck with whatever initial version you choose. -- Jack Stewart IMSS, California Institute of Technology, M/C 1-10, 1200 E.

[Dovecot] PAM session closes too soon
by Lauri Alanko 16 Aug '08

16 Aug '08

Hi. I'm trying to keep most of my data encrypted when possible, only keeping the decryption key in memory (and thus vulnerable to local attacks) when I'm actually using my data. In practice, this means using pam_mount to mount my home directory from an encrypted device. It almost looked like I could get this to work with mail as well, even when read via IMAP from a remote client: I placed my mail in the encrypted home directory, added pam_mount to /etc/pam.d/dovecot, and set session=yes in Dovecot's PAM configuration. Except that it didn't, quite: pam_mount worked just fine and mounted the encrypted disk using the IMAP password... and then immediately unmounted it, since for some reason session=yes means that Dovecot closes the session _immediately_ after opening it. This seems just silly. If a PAM session is to be used, then it seems obvious to me that its length should be exactly the length of the IMAP session. I can't see any reason for the current behavior, except maybe that it was a bit simpler to code and is sufficient for pam_mkhomedir (and only that). Can this be fixed with reasonable effort? Also, for pam_mount to work correctly, there must not be any file descriptors open in the mounted file system when the session closes, as otherwise unmounting is impossible. Will dovecot release all fds into the mail and index files when the session ends, or can it be made to do so? (UTSL is an acceptable answer.) Thanks in advance. Lauri Alanko la(a)iki.fi

Just installed dovecot 1.1.2. downloaded from dovecot.org. Seemed to compile and install OK but I get the following error when I try to start it "child 28410 (auth) returned error 89 (fatal failure)" I just want to use it for SMTP/SASL authorization, not Pop3 or IMAP, as yet It looks as though I haven't installed some component or other but what?

[Dovecot] Problem with squirrelmail and dovecot 1.1
by Gerhard Wiesinger 16 Aug '08

16 Aug '08

Hello! I'm running squirrelmail 1.4.8 (I know this is not the latest version) and know I'm having troubles with: 1.) Folder list view 2.) Save to sent or Drafts folder. Configuration worked well. I think it has to do with the upgrade from dovecot 1.0 to 1.1 and the LIST command. Thunderbird/alpine work well. Commands from rawlog are: A002 LIST "" "~/Mail/Drafts" A002 OK List completed. or A002 LIST "" "~/Mail/sent" A003 CREATE "~/Mail/sent" A002 OK List completed. A003 NO Mailbox exists. Has something changed in the folder behaviour of dovecot from 1.0 to 1.1? If you need more information please let me know it. Any ideas? Thnx. Ciao, Gerhard -- http://www.wiesinger.com/
