by Mike Foley 05 Mar '05

Hi, I'm trying to move from UW-IMAP to Dovecot. This is on a RedHat 7.3 system and I'm using the Dovecot RPM from Dag Weirs site. dovecot-0.99.13-1.0.rh7.rf.i386.rpm http://rpmfind.net/linux/RPM/dag/redhat/7.3/i386/dovecot-0.99.13-1.0.rh7.rf… When I start up Dovecot, I get the following: dovecot: Dovecot starting up Feb 28 01:41:54 yelofsrv dovecot: Auth process died too early - shutting down Feb 28 01:41:54 yelofsrv dovecot: child 13724 (auth) returned error 127 Feb 28 01:41:54 yelofsrv imap-login: fd_send(-1) failed: Broken pipe I'm just trying to do a simple PAM/passwd type login. No MySQL/LDAP/PGSQL stuff. I've Googled till the cows came home (almost literally. I was up till 2am last night searching) and can't seem to find a straight answer. Any help/pointers? thanks, mike

[Dovecot] mbox or maildir?
by Brian Read 04 Mar '05

04 Mar '05

I am using dovecot in an SMEServer (aka e-smith), and recently backed-up on one system and restored on another system the imap email directories. The trouble was that dovecot "guessed" the mail type wrongly, and I ended up with "empty" ~/Mail directories (did it create or populate these?), and full, but ignored ~/Maildir directories for every user. Could someone point me to the chapter and verse of how (and when) dovecot decides which type of mail is in use, and how you can change the decision. I tried editing /etc/dovecot.conf, but that didn't seem to make any difference. Using dovecot 0.99-10 under a Redhat 7.3 base on kernel 2.4.20-18.7 -- Cheers Brian http://www.abandonmicrosoft.co.uk

[Dovecot] Dovecot response to "FETCH" command
by Alex Tang 04 Mar '05

04 Mar '05

Hi folks. I just converted my site from UW+mbox to dovecot+maildir (stable-test59, 2005/02/25). For the most part, everything is great. The server seems faster and less memory intense than the UW server (this part has made me very happy). And it's definitely more user friendly to me than Courier. There is one thing however... A few of my users are using the web based mail reader (Squirrelmail-1.2.11) that i provide for them. Once i converted to dovecot, the squirrelmail users were reporting that when viewing the folder list page, 2 things were happening: * The date for all of the messages was being displayed as "Sun 4:00 pm" * all messages were shown as being "new". they never would be transferred into the "Seen" state. After doing some IMAP protocol sniffing, i found this difference in the way that the UW server and the dovecot server handles the "FETCH" command... Squirrelmail issues a FETCH command to get message header information like this (lines broken with backslashes for readability): A009 FETCH 1:1 (FLAGS RFC822.SIZE INTERNALDATE BODY.PEEK \ [HEADER.FIELDS (Date To From Cc Subject X-Priority \ Content-Type)]) The UW server returns: * 1 FETCH (FLAGS () RFC822.SIZE 710 \ INTERNALDATE "27-Feb-2005 23:50:42 -0800" \ BODY[HEADER.FIELDS ("DATE" "TO" "FROM" "CC" "SUBJECT" \ "X-PRIORITY" "CONTENT-TYPE")] {153} Date: Sun, 27 Feb 2005 23:50:42 -0800 From: root <root(a)scorchedearth.us.proofpoint.com> To: altitude(a)scorchedearth.us.proofpoint.com Subject: asdf When the same FETCH response is returned by dovecot, the response looks like this: FLAGS () RFC822.SIZE 3358 INTERNALDATE "27-Feb-2005 07:55:27 -0800") * 1 FETCH (BODY[HEADER.FIELDS (DATE TO FROM CC SUBJECT X-PRIORITY CONTENT-TYPE)] {205} Date: Mon, 28 Feb 2005 00:04:22 +0800 From: xxx xxx <xxx(a)xxx.com> To: dovecot(a)dovecot.org Content-Type: text/plain; charset=UTF-8; format=flowed Subject: [Dovecot] "not listening" notification I noticed that in the UW response, the "* 1 FETCH ..." is the first line, and contains all of the data except for the message header info. However, in the dovecot response, the data is split into 2 lines, and the first line is not the "* 1 FETCH" line. In reading through the squirrelmail source, squirrelmail is not recognizing this as a valid response, and thus the date, size, and flags are not being properly set in the internal squirrelmail message objects. This explains why both the date as well as the "seen" status of the message is never properly set. OK, after all this blabbing on...here's my question. Is the data being sent back by dovecot a valid response? My knowledge of the IMAP protocol is weak to say the least. I tried reading the IMAP RFC (3501), in particular section 6.4.5 which defines the FETCH command), and the RFC seems to specify that the response should have the "* # FETCH" lines come first. However, the RFC seems vague, and i didn't wade through any of the other RFCs out there. I figure it is legal, since the two other clients i've used seem to understand it just fine (thunderbird/mozilla, mutt). However, could this be the reason why mozilla/thunderbird sometimes gets the message size wrong (and hence why the "tb-negative-fetch" workaround is needed). For now, i'll bang on squirrelmail to support the response sent by dovecot. Thanks. ...alex...

[Dovecot] hanging imap... and users getting other users' emails!
by Josh Burley 03 Mar '05

03 Mar '05

Hi All, We recently upgraded from UW (boy, starting to sound like a broken record, eh?)... Two problems: 1. Every two or three days users are unable to access their email via IMAP. It seems that it's because dovecot-auth has hung. Has anyone seen anything like this? 2. (the really serious one)... one of our users, "angie" has twice had her Outlook download other users' email! Once as another user, "helene", and just now as "mkarlin". The first time she got 800 of helene's email, and just now, about 30 of mkarlin's.... from our log, I noticed: Mar 2 17:27:10 core imap-login: Login: mkarlin [::ffff:128.195.131.2] Mar 2 17:27:10 core imap-login: Login: mkarlin [::ffff:128.195.131.2] Mar 2 17:27:11 core pop3-login: Login: angie [::ffff:68.231.223.128] Mar 2 17:27:11 core imap-login: Login: mkarlin [::ffff:128.195.131.2] Mar 2 17:27:11 core imap-login: Login: mkarlin [::ffff:128.195.131.2] Our server setup: Fedora Core 3. dovecot-0.99.13. OpenLDAP, and dovecot auth'ing off PAM (mostly default setup, using Mailbox, and mail/ as a subdir). Any ideas? Any more debug info I can supply? .josh

[Dovecot] selective POP3 user
by Barry Kwok 03 Mar '05

03 Mar '05

I want to know if it is possible to limit some users to use POP3 service only in a server running BOTH IMAP and POP3 service. In other words, some users can choose IMAP or POP3 and some users can only use POP3. Barry

[Dovecot] Several issues with 1.0-stable
by Remy Zandwijk 03 Mar '05

03 Mar '05

All, We have Dovecot 1.0-stable deployed in our 3000 users environment as of last weekend. Up untill now, I have 3 issues: - When stopping Dovecot with: kill -TERM `cat /var/run/dovecot/master.pid`, the 'dovecot' process itself dies, the 'imap-login' processes die, but the 'imap' processes (there are a lot of them) don't die, but become a zombie. I think the way I stop Dovecot is the way to do it. The zombies can be killed by doing a 'pkill -9 imap', but that's not quite elegant. - Dovecot is running in a Solaris 9 environment. It turned out that Dovecot crashes when more then 256 filedescriptors are being used. This is rather normal, since Solaris only support 256 descriptors per 32-bit process. After starting Dovecot, I do a 'plimit -n 8192, 8192 `cat /var/run/dovecot/master.pid`, which allows Dovecot to have 8192 filedescriptors. Timo, is it possible to introduce a config file option to configure the number of descriptors? - Pine and Outlook users don't see the adresses or names of the people who sent them email. In my email yesterday, I said I remembered that tests with Dovecot 0.99 showed no problems. Today, I installed both Dovecot 0.99 and 1.0-stable on my test box. It turned out that 0.99 indeed works OK and that 1.0-stable is the problem. The user mailboxes are 'Maildir'; we do not use mbox format. I like to see this problem being fixed..... We have 2 namespaces in our setup: the default namespace and a namespace which location is set to ~/.Mailstorage. When not using a prefix in the email client setup, users can make new email folders in the default namespace and the 'Mailstorage' namespace. We want users only to create mail folders in the Mailstorage namespace, not in the default namespace. Questions: - Is it possible to force a prefix to clients? - If not, is it usefull to have an option in the namespace configuration that allows or disallows the creation of mail folder? If so: consider this as a feature request. Thank you for reading, best regards, Remy Zandwijk Free University of Amsterdam The Netherlands

[Dovecot] Newby Question
by Troy Bull 03 Mar '05

03 Mar '05

Hello I just setup my IMAP server and everything works great, except for 1 small detail. I am upgrading from uwashington's imap server, and in theirs I had to put a directory "mail" in for the imap folder (this is on the client). The problem I have is with dovecot this makes an extra level (I think). So on my server ~/mail is where the mail folder is located, but when the client puts in the "mail" for the imap server directory dovecot looks in and creates folders in ~/.mail/mail. This is a problem for me because I have many clients and I would have to go reconfigure each one. My question is this, is there a way to make dovecot look in ~/ so that when combined with the imap folder from the client it ends up in ~/mail? I hope that is clear enough, I was thinking maybe I need to set default_mail_env, but i have no idea to what? Thanks in advance Troy
