[Dovecot] Can't create subfolders of my INBOX or delete folders with IMAP
by Matthew Exon 07 Mar '05

07 Mar '05

Hi, I've been using the dovecot IMAP server for about a year now, and basically it works. But there's an annoying problem, that I can't make any subfolders. I can only make folders that are at the same level as my INBOX folder. Worse, I can't delete folders once I've created them. I'm using Debian unstable on both the server machine and my client machine. The dovecot version is 0.99.13. For my mail client, I'm using Mozilla Thunderbird version 1.0. I've done a bit of investigation on my filesystem, and by googling for all kinds of stuff, but I'm really drawing a blank on this particular problem. Most of the general linux email documentation I've found either doesn't mention IMAP, or doesn't mention dovecot, or both. I can barely find any references to the concept of "subfolder" at all. I really don't want to know anything about email servers, I just want the bloody thing to work. Trying to figure out what the hell's going on is really frustrating! On the server, I seem to have various mailboxes distributed around the place. I've got a mail box in /var/spool/mail. I've got a file ~/mbox, which seems to be very old and is therefore probably a red herring. I've also got a directory ~/Mail with a bunch of files in, one for each of my folders. Having some of my mail in /var/spool, and some in my home directory, seems a really horrible way of arranging things, but anyway... Various online sources seem to suggest that maildir is better than mbox. I don't have any particular preference for one or the other, but I don't want to change if I don't have to because: 1) From experience, I don't screw with settings if I don't have to. Debian made it that way, and changing it behind Debian's back is a surefire way to cause trouble later. 2) Any other accounts on that machine (especially ones I might create in future) will probably still be mbox, causing even worse confusion later. 3) Porting mailboxes is always risky, and I don't want to lose my mail, or have incoming email dropped, or accidentally corrupt it, or anything like that. So I'm not going to do any of that unless I'm sure that it's actually going to fix the subfolder problem, and until now I haven't found any information anywhere to guarantee that that's the case. Intuitively I can guess that if a folder is just a big file full of concatenated email, then making a subfolder is going to be pretty much impossible, but I don't want to guess here. The actual symptoms in thunderbird are: When I select "New folder...", I get the "Create as a subfolder of:" dropdown hierarchy box thingy, but the "Inbox" option is greyed out (side complaint: no user interface should ever have a greyed out option without providing an explanation as to why it's not available, and what you should do if you want it to be available. Displaying it like that is just cruelly teasing the user). When I try to delete a folder, I get a dialog box saying "The current command did not succeed. The mail server responded: Mailbox doesn't exist: <name of folder>". This is pretty frustrating, because I can *see* the damn thing in thunderbird. (another side complaint: "The current command"? You're *running* the bloody command, you should have a better description than that!) For some reason though, I can rename a folder with no problems. I went into /var/log/ on the server, to see what was in the Dovecot log file about the server errors above, but there *is* no log file, nor anything in the syslog. That can't be good. How do you tell the sysadmin when there's a problem? Does anyone have any suggestions for how I can fix this? And if possible, I want to fix this the Debian way, that is by modifying a debconf setting or a /etc/default file or something like that, so that when I upgrade Debian, or uninstall dovecot and then reinstall it, it'll be handled gracefully. Thanks, Matthew Exon

[Dovecot] pop before smtp
by F. Even 07 Mar '05

07 Mar '05

I'm using the latest version of dovecot on my FreeBSD 4.x box with OpenPKG to keep other services up to date. Now...I'm able to get pbsmtp to allow relaying through postfix on this server using UW IMAP, but I would like to get dovecot working with relaying...but pbsmtp is not adding the ip when I uncomment the dovecot section after I authenticate. The log is below: [root@cerebus:/opt/sbin] ./pop-before-smtp --version version: 1.36 Mar 4 05:14:09 cerebus last message repeated 5 times Mar 4 05:19:46 cerebus dovecot: Killed with signal 15 Mar 4 05:20:00 cerebus dovecot: Dovecot v1.0-test62 starting up Mar 4 05:20:34 cerebus dovecot: imap-login: Login: user [ip.ad.dr.ess] Mar 4 05:30:21 cerebus dovecot: imap-login: Login: user [ip.ad.dr.ess] I had uncommented the stock pattern in the latest version to no avail: # For Dovecot POP3/IMAP #$pat = '^(... .. ..:..:..) \S+ (?:dovecot: )? (?:imap|pop3)-login: ' . # 'Login: \S+ \[(\d+\.\d+\.\d+\.\d+)\]'; Thanks for any help anyone might be able to provide. Frank

[Dovecot] No 'from' in messages
by Remy Zandwijk 06 Mar '05

06 Mar '05

Hi all, Over the weekend, we've migrated our old mail environment to Sendmail and Dovecot: - Dovecot 1.0 stable - Sendmail 8.13.3 - Procmail 3.22 Procmail is MDA for Sendmail and it delivers mail to Maildir boxes. Email clients like Eudora, Thunderbird, Outlook and mutt are working OK. When using Outlook Express and Pine however, in the message list the 'from' or 'sender' field is empty. This means users of these programs cannot see who did send the mail to them. When running Dovecot 0.99 in a early test period, this problem did not occur. Question: Did anyone see this behaviour before and how to fix it? Best regards, Remy Zandwijk

[Dovecot] Dovecot 1.0-stable .deb file?
by Ian R. Justman 06 Mar '05

06 Mar '05

Hi, all. I know that there's no official Dovecot 1.0-stable .deb, given Timo's recommendations. However, does anyone have even an "unofficial" deb of it for, say, Sarge? I want to use 1.0's ability to use both mbox and maildir; the latter is very helpful for dealing with mailing lists. Thanks in advance for any help. --Ian.

[Dovecot] Password scheme overides

I notice in the wiki you can have password sceme overides (such as {PLAIN}password). Would this work with the password fields in SQL databases (as it isn't clear in the wiki or conf file)? Regards Andrew -- Andrew Hutchings Linux Guru Netserve Consultants Ltd. http://www.domaincity.co.uk/

[Dovecot] dovecot-pgsql.conf can't find in chroot? (debian)
by Matthew J. Harmon 06 Mar '05

06 Mar '05

In my original email I noted that the directory /usr/local/etc was in the dovecot.conf variable valid_chroot_dirs : valid_chroot_dirs = /usr/local/etc:/etc:/var/mail:/lib Is that not sufficient? Under the /var/run/dovecot directory the directories ./usr/local/etc exist with dovecot-pgsql.conf in. Is there some big RTFM item I'm missing here? -Matthew P.S. - email address changed due to problems with upstream, will jump back as soon as this is fixed so I can finish my migration :) On Sat, 2005-03-05 at 09:06 +0100, Gunter Ohrner wrote: > Am Samstag, 5.

[Dovecot] Still having problems deleting messages through IMAP

05 Mar '05

Hello, I am using SquirrelMail with the 1.0 releases, and I have even backed up to the latest stable release based on 1.0. I am using MailDirs. When I delete a message, the message still shows up in the message list until either I log out and back in or a new message arrives in that folder. Any ideas? Thanks Doug Eubanks doug(a)simflex.com The speed of time is one-second per second.

[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

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

[Dovecot] Trigger getmail via mail-client action?
by Gert Brinkmann 03 Mar '05

03 Mar '05

Hello, I want to use dovecot on my private debian/unstable-system to have the advantages of an IMAP-Server (Access to mails from different computers, Simply changing the mail client). I decided to use dovecot, because I very often have read (in the web) that it should be more simple to configure than other servers. Now I have the following question: I want to use getmail to retrieve mails from my provider's pop3-server. I do have a dial-up-connection that is not online permanently (I do not have a flat rate). I could start a script on ppp's ip-up that periodically invokes getmail and on ip-down to kill it again. But I would prefer to invoke getmail only when I really want it to be run. The ideal solution for me was to invoke getmail when the "Get Mail"-Button of the mail client is pressed. Is this possible? Perhaps there is something like a connection- or refresh-trigger in dovecot? Thank you, Gert

Re: [Dovecot] Too many open files, etc.

Martin, we're dealing with the same problem right now. We are using dovecot 1.0 stable and we migrated last weekend. 32-bit processes in Solaris 9 have 256 filedescriptors avail- able. This seems a bit to small. Using this command to get the number of file descriptors used by dovecot: ls -1 /proc/`cat /var/run/dovecot/master.pid`/fd | wc In our enviroment this is currently around 390. You can limit the number of file descriptors per process in Solaris 9. After starting Dovecot, we issued the command: plimit -n 8192,8192 `cat /var/run/dovecot/master.pid` This gives Dovecot 8192 filedescriptors. HTH, Remy

I've installed dovecot 0.99.14 (maildir, postfix, RHEL3) and I would like to create , for every user, 4 mailbox (in skel): mail-sent, spam, virus-alert and sysadm. Procmail, parsing header mail, will move mails into a specific mailbox. Every users could move, delete, read these mails but they must not delete mailbox folder (such as INBOX mail).

[Dovecot] APOP
by Steven Stern 25 Feb '05

25 Feb '05

I want to turn off POP3 and use POP3S in its place. So far, it's working well for Outlook and Thunderbird. But I'm running into problems with Agent: It supports APOP but not POP3S. Is there a way to have Dovecot support APOP authentication on a normal POP3 connection? I'm running 0.99.13 on Fedora Core 3. -- Steve

[Dovecot] A few words about NFS please?
by Jeff A. Earickson 25 Feb '05

25 Feb '05

Hi, Could you say a few words about Dovecot and POP/IMAP to an NFS mounted filesystem? I thought I saw on the dovecot webpage that NFS is "no way" with 0.99 and "maybe" with 1.x. I was looking for the FAQ and couldn't find it. My setup is like so: My mail server is a Solaris 9 system, running sendmail/procmail, and qpopper POP. Mail is stored in mbox format. The /var/mail filesystem is NFS exported to another Solaris 9 system that runs UW-IMAP. The user community also has login access to this second system, so there are also local email clients like Pine and emacs using the NFS /var/mail. So, POP and sendmail/procmail accesses /var/mail locally, while UW-IMAP accesses it via NFS. The user community has been warned to do either POP or IMAP, but not both. There are very few problems with this setup. I would like to use Dovecot for both POP and IMAP on the two machines. I know NFS is frowned upon, but this has worked for me. Comments and suggestions, please? Jeff Earickson Colby College
