[Dovecot] strange email client problems
by Gabriel Granger 22 Mar '05

22 Mar '05

I've got some issues with dovecot, that I need to resolve, I only have about 20 users in the office, but the average disk space used by each user is anywhere from 1GB up to at the extreme end of the scale 7GB. I'm using the mailbox format. The server is a P4 2.8 with a 1GB of ram and run off 250GB SATA disks. most users have lots of structured folders going as deep as 6 levels. The problems I'm getting are odd the problems that I'm getting at the moment are "cannot copy mail to sent folder", but sends the message fine, this doesn't happen all the time but happens to everyone but me... I'm using OS X's Mail.app which seems to always work:) all my users are using W2K and either ThunderBird or Mozilla The other problem which I've been made aware of... The users get the "loading message" or "opening messages" and the egg timer goes round but never completes. I managed to clear the problem by getting the user to close their email client and then kill their IMAP processes on the server, when the user logs in again the client responds correctly. Is there something I'm doing wrong with the configuration of dovecot? would using MailDir help, I dont want to migrate from Mailbox unless this change will make things better, I understand their are benefits from using MailDir, but I dont know if I will continue to see the same problems if I migrate. Any help or advise would be great, I should add that everyone is connecting to the server over SSL Gabe

[Dovecot] emulating courier imap

I'm trying this: default_mail_env = maildir:%h/.maildir:INDEX=%h/.indexes:INBOX=% h/.maildir namespace private { separator = . prefix = INBOX. inbox = no } namespace private { separator = . prefix = inbox = yes hidden = yes } but dovecot doesn't appear to be honoring "hidden" - am I missing something? (that is, all my folders appear twice- one under INBOX, the other under root) I tried without the second segment, and makign the first one "inbox=yes" - but then I got two inboxes... -- Internet Connection High Quality Web Hosting http://www.internetconnection.net/

[Dovecot] Mixing mbox and maildir
by Tom Alsberg 21 Mar '05

21 Mar '05

Hi there. I understood that in Dovecot 1.0 it should be possible to mix the usage of mbox and maildir mailboxes. I just downloaded, built, and am testing dovecot-stable-20050304. I'm a bit confused as to the terms of namespaces (haven't read that part of the RFC yet), but this does not seem related. Anyway, when I try specifying: default_mail_env = ~/mail/:INBOX=/var/mail/%u On login I'm immediately disconnected, seeing something like: dovecot: IMAP(user): Failed to create storage with data: ~/mail:INBOX=/var/mail/user in the log file. This seems more like a bug to me (or maybe something in permissions I haven't noticed - but I've checked...) Any way, according to the documentation, it will detect whether ~/mail/ is mbox or maildir - but would that enable having both mbox and maildir in that directory? The goal is, to deploy Dovecot 1.0 at some time, while here there are users who have both maildir and mbox mailboxes (I.E. spool is mbox, ~/mbox is mbox, ~/mail contains some mbox mailboxes for small stuff that users want to be able to access even using /usr/bin/mail, and some larger maildir mailboxes (less critical, or high volume - e.g. mailing lists). How is that possible? Thanks, -- Tom P.S. Thanks again, Timo and rest of developers for this big piece of code - I maintain Dovecot 0.99 in another place and it's by far the most useful IMAP server yet. -- Tom Alsberg - hacker (being the best description fitting this space) Web page: http://www.cs.huji.ac.il/~alsbergt/ DISCLAIMER: The above message does not even necessarily represent what my fingers have typed on the keyboard, save anything further.

[Dovecot] Shared maildirs with symlinking
by Gauthier Vandemoortele 21 Mar '05

21 Mar '05

Hello, I try to set up a shared maildir with symbolink links, but it doesn't work. The main user, from which I would share a mailbox, creates a mailbox named "Commun" with thunderbird. I see on the file system from the server that a directory .Commun is created in his ~/Maildir/ and that the file ~/Maildir/.subscriptions has now such an entry. Right. In ~/Maildir/Commun the permissions are /cur 700 /new 700 /tmp 700 .customflags 600 .imap.index 600 .imap.index.data 600 .imap.index.log 600 .imap.index.tree 600 dovecot-uidlist 600 and as owner MainUser/users (I work on a slackware 10, all the users have by default the group users.) So, I change all the rights to 770 for directories and 660 for other files (I don't forget .Commun itself) Now the other user ; he creates also a folder named "Commun", so that such an entry exists in .subscriptions. As admin, I delete his folder ~/Maildir/.Commun, and create a symbolink link ~OtherUser/Maildir/.Commun pointing to ~MainUser/Maildir/.Commun Now MainUser moves a mail in his folder Commun, always with thunderbird ; OtherUser sees now a message in the "same" folder, but he can't read it. In fact, Thunderbird displays a little icon but without textuel information, like subject, or so. If OtherUser clicks on it, the mailer hangs indefinitly. It's logical, the file created in ~MainUser/Maildir/.Commun has 600 as permissions. On the other hand, OtherUser can move or create a file in his folder Commun, but MainUser does'nt see it, I suppose because his index is not updated. I had read in http://wiki.dovecot.org/SharedFolders that : It's important to have dovecot-shared file created in the shared maildir with the permissions and group ID you want to have access to the mailbox. Dovecot uses the same permissions and GID when it creates index files, dovecot-uidlist file, new mail files, etc. With my experience, it seems that Dovecot creates the file regardless of the permissions of the shared folder. Can someone say how to resolve that ? I use dovecot-0.99.11 Thanks in advance, -- Gauthier Vandemoortele <gauthier.vandemoortele(a)skynet.be> ...

[Dovecot] Loading messages
by Gabriel Granger 19 Mar '05

19 Mar '05

Thanks to all for pointing out the Thunderbird bug workaround, I've got another question Some of my users are complaining that when they select a message, the email client says "Loading Message" and either takes a long time to display a small message or does not display the message at all. Its odd becuase it seems that larger message on these users machines seem to open more quickly then the small 1Kb - 15Kb messages. Looking a little further on the messages that wont open they all seem to be very small in size. Is this a common issue? or something i need to tweak on the dovecot.conf or on the client side? Gabe

[Dovecot] problems with migration to Maildir
by F. Even 19 Mar '05

19 Mar '05

I'm attempting to use Maildir and mbox together until I can finish migrating all mailboxes and figure out issues I'm having with a couple other mailboxes. But, I want to officially start using Maildir as the primary msg. store. Now...when I configure Dovecot as follows, it creates new folders in the ~/mail folder, which is where my mboxes reside: #default_mail_env = #default_mail_env = mbox:~/mail/:INBOX=~/mbox #default_mail_env = mbox:~/:INBOX=~/mbox #default_mail_env = mbox:~/mail:INBOX=~/mbox default_mail_env = maildir:~/Maildir #namespace private { # separator = / # inbox = yes # prefix = # location = mbox:~/mail:INBOX=~/mbox #} #namespace private { # separator = / # prefix = "Maildir/" # location = maildir:~/Maildir #} namespace private { separator = / inbox = yes location = maildir:~/Maildir } namespace private { separator = / location = mbox:~/mail } I would like to have access to the mbox hierarchy, but I want all new folders by default created in ~/Maildir. How do I go about acheiving this? Thanks, Frank

[Dovecot] postfix + SMTP AUTH using DOVECOT AUTH DAEMON
by Ing. Alejandro Rodriguez 18 Mar '05

18 Mar '05

hi ppl I'm the new member of the list. Looking at recent messages look like there is a way to do SMTP AUTH in postfix using the Dovecot AUTH daemon. Currently my Dovecot installation auth again PAM (local users) and a simple shadow file (for virtual users, I plan to move to MYSQL later). I don't want to have different databases one for dovecot a one for SASL. Where I can found the POSTFIX patch, or better, some kind of helper daemon for Postfix. thx A

[Dovecot] Namespaces and subscriptions
by Chris Wakelin 17 Mar '05

17 Mar '05

I've got a problem with subscriptions in 1.0-stable when migrating from UW-IMAP. I've modified the SUBSCRIPTION_FILE_NAME entries as suggested in the Wiki http://wiki.dovecot.org/Migration and included the "~/mail/" etc. hidden namespaces. The .mailboxlist files contain entries like "~/mail/somefolder" and the clients have "~/mail/" set as a prefix. In UW-IMAP: xyz LSUB "" "*" * LSUB () "/" ~/mail/somefolder xyz LSUB "~/mail/" "*" * LSUB () "/" ~/mail/somefolder Now with Dovecot: xyz LSUB "" "*" * LSUB () "/" "~/mail/somefolder" xyz LSUB "~/mail/" "*" * LSUB () "/" "~/mail/~/mail/somefolder" In other words, Dovecot is prepending the namespace to the list of folders stored in .mailboxlist. This causes Thunderbird to show the folders as -~ - mail | somefolder which are accessible. Squirrelmail gets completely confused and tries to display "~/mail/~/mail/somefolder" (but works with the prefix set to ""). Am I missing something? I tried Geo's empty namespace patch, just in case that would help, but it didn't.

[Dovecot] 1.0-test65
by Timo Sirainen 16 Mar '05

16 Mar '05

http://dovecot.org/test/ If dovecot-auth was crashing with you, this release should fix it. I don't know when it did though, I just applied a patch from Andrey Panin with that description :) Fixed also another dovecot-auth crash with Solaris and maybe some other systems. Contains the first attempt of a Dovecot LDA. It's still in pretty ugly shape, but it should work, more or less. I wouldn't recommend using it in production yet. There are two ways to use it: 1. As a normal user. The username is taken from passwd. 2. Giving -d <username> option. This connects to dovecot-auth and requests the uid, gid, home, etc. from it. dovecot-auth's master socket is expected to be in /var/run/dovecot/auth-master but you can override this with -a parameter. To actually create the auth-master socket you'll need to add this inside auth { .. } : socket listen { master { path = /var/run/dovecot/auth-master mode = 0600 } } Dovecot LDA also currently needs dovecot-lda.conf file. Everything that is read from it is just dumped into environment variables internally. You should be able to set pretty much all the same settings in there as exists in dovecot.conf. The most important exception is that instead of default_mail_env there's just "mail". Example dovecot-lda.conf would be: # note that namespaces aren't supported yet.. mail = mbox:~/mail:INBOX=/var/mail/%u mbox_read_locks = flock mbox_write_locks = flock # EOF All this goes away once I get the config process implemented. The actual usage goes something like: /usr/local/libexec/dovecot/deliver -d username < mail_file ie. the mail is read from standard input. Any suggestions if the "deliver" name should be changed and maybe moved to /usr/bin/? Another large change is that I created dynamically growing array implementation with possibility to do compile time type checking. The old code was using buffer_t for arrays, but that got pretty ugly. I changed most of those in lib-index/ to the new array API. I'd be happy if someone changed the rest of them since it's pretty boring and time consuming job :) See lib/array.h for explanation how it works.

[Dovecot] corruption and errors in dovecot-stable

16 Mar '05

Hi, We switched from dovecot 0.99.something to 1.0-stable (on FreeBSD 4.10) a few days ago and have been seeing many errors and one corrupted mailbox so far. Almost everyone uses mbox format, and most users primarily use SquirrelMail; I use Apple Mail and Thunderbird, as well as accessing the mailboxes locally with Mutt, and have not noted any visible problems.

[Dovecot] imap-login zombies
by Robin Breathe 16 Mar '05

16 Mar '05

Running dovecot-0.99.13 on Solaris9/Sparc with ~25k users, we are having regularly recurring problems with large numbers imap-login/pop3-login drones, cycling on poll(). Over the course of 1-2 days, the number of such processes slowly rises to >1000, exhausts resources, and necessitates that dovecot be restarted (having killed all current active and zombie child processes). Nothing of interest seems to be logged with the possible exception of a reasonably high number of aborted logins (~10/hour). Can anyone offer any guidance as to how to track down this bug and help get it resolved? Any help would be much appreciated, as we would very much like to see this resolved in the 0.99 branch.

My /etc/pam.d/common-* looks like this, which simply means try /etc/passwd first, and try LDAP using the same password if it is failed. account [success=1 default=ignore] pam_unix.so account required pam_ldap.so use_first_pass account required pam_permit.so auth [success=1 default=ignore] pam_unix.so auth required pam_ldap.so use_first_pass auth required pam_permit.so session [success=1 default=ignore] pam_unix.so session required pam_ldap.so use_first_pass session required pam_mkhomedir.so skel=/etc/skel umask=0002 session required pam_permit.so When many LDAP users login, /var/log/auth.log shows many (expected) error like: (note "pam_unix") Feb 3 18:16:15 eta dovecot-auth: (pam_unix) authentication failure; logname= uid=0 euid=0 tty= ruser= rhost=127.0.0.1 Feb 3 18:16:19 eta dovecot-auth: (pam_unix) check pass; user unknown After recent upgrades from probably 0.99.10 to 0.99.13, these lines begin to appear in /var/log/mail.log: Feb 3 16:31:00 eta dovecot-auth: Login process has too old (123s) requests, killing it. Feb 3 16:31:00 eta dovecot-auth: Login process has too old (124s) requests, killing it. And some more like this, which shows the problem: Feb 3 16:45:23 eta dovecot-auth: I/O leak: 0x8054940 (13) Feb 3 16:45:23 eta dovecot-auth: I/O leak: 0x8054940 (14) Feb 3 16:45:23 eta dovecot-auth: I/O leak: 0x8054940 (15) The problem can be solved by changing /etc/pam.d/dovecot to: auth required pam_ldap.so account required pam_ldap.so session required pam_mkhomedir.so skel=/etc/skel umask=0002 session required pam_ldap.so This change means PAM not fail auth for /etc/passwd again. I think dovecot has some problem dealing with the pam_unix + pam_ldap configuration. Do you have any idea? I am Cc-ing this message to the corresponding bug in Debian BTS. -- Regards, Alan

[Dovecot] Bit of a Newbie Question
by Jud 16 Mar '05

16 Mar '05

Apologies in advance - I'm sure there's something quite obvious I'm not doing correctly, but since I'm unable to resolve the problem myself.... I've installed Dovecot 99.14 on FreeBSD-CURRENT using the Dovecot FreeBSD port. My "network" consists of a cable modem connected to a router which is in turn connected (only) to my computer. My ISP assigns a dynamic IP address. I have ddclient set up to sync the dynamic IP to my hostname and MX via dyndns.org. Local operations (local delivery via Postfix or copying/moving/deleting with Thunderbird) work fine. Mail delivery from remote machines does not seem to work via either IMAP or IMAP-SSL. (That is, test e-mails I send from this [Fastmail] account to my local IMAP server never reach their destination.) Enabling port forwarding on my router for ports 993 and 143 has made no difference. What should I be doing to make this work correctly? Jud

[Dovecot] Strange behaviour with moving mail
by Remy Zandwijk 15 Mar '05

15 Mar '05

Hi All, Sorry to bother you again. I am not too familiar with IMAP yet, so maybe I am asking stupid questions. Here goes anyway: In our (Dovecot 1.0-stable) setup, we have two namespaces: the default namespace, which location is '/var/mailstore/1%u/%u' and the "Mailstorage" namespace, which location is '~/.Mailstorage/'. Now we create a folder called 'Test' in the default namespace and the "Mailstorage" namespace. As far as I know this is possible and not a strange thing to do. When moving an email from the first 'Test' folder to the other 'Test' folder, it appears that everything works like expected, but when refreshing the mailbox, the message is still in the original folder. This happens with a number of different mailclients (which are configured with an empty namespace setting). I guess Dovecot doesn't look at the namespace in which the mail folder is. Is this a Dovecot bug or is this normal behaviour? Best regards, Remy B.T.W: When moving the mail, this is the IMAP conversation: 00029 UID COPY 4 TEST * 2 EXISTS * 2 RECENT 00029 OK Copy completed. 00030 UID STORE 4 +Flags.silent (\Deleted) 00030 OK Store completed.

[Dovecot] Is it possible to regenerate the index files?
by Joakim Verona 15 Mar '05

15 Mar '05

Is it possible to regenerate the index files, on other conditions than the mbox file being read? For instance, it would be nice if I could regenerate the index for a specific mbox whenever procmail delivers mail to it. If theres no existing solution, would it be possible to make a small script with something like "nc" that could send an imap command to dovecot, so that dovecot would rebuild its index for that mbox? If so, which imap command triggers an index rebuild? -- Joakim Verona www.verona.se

[Dovecot] Visibility of .subscriptions and .customflags
by justin 15 Mar '05

15 Mar '05

Hi, I upgraded to test65 from 0.99 (mostly to get the namespace feature) and now it seems my .subscriptions and .customflags are showing up as mail folders in my IMAP client (Eudora). If I try and open those folders, of course I get an error. How can I configure dovecot so that these aren't displayed to my IMAP client? I looked through about 6 months of acrhives and couldn't find it mentioned anywhere. Thanks.

[Dovecot] logging
by F. Even 15 Mar '05

15 Mar '05

I'm curious about exactly what this means in my log: Mar 13 10:56:20 cerebus dovecot: imap-login: Disconnected [130.94.242.20] Mar 13 10:56:51 cerebus last message repeated 177 times Mar 13 10:57:32 cerebus last message repeated 179 times Now...does Dovecot ONLY log the names of users on successful attempts? Is this "Disconnected" log entry an indication someone ran a username/password attack against the imap server and failed to authenticate? If so, is there any way to make this a little more verbose, so I can perhaps see what names, etc. the annoying idiot is throwing against my server....? Thanks.

[Dovecot] (no subject)
by Gabriel Granger 15 Mar '05

15 Mar '05

Hi All, Bit the bullet last night and switched off UW-IMAP and turned on Dovecot. With any migration I've got some teething problems and hoping someone might be able to point me in the right direction. I tested the system using apple's Mail.app which worked fine, no problems at all, but it seems that most of my users are getting problems, i suspect Mail.app is hiding these messages from me. All my users are using ThunderBird 1.0 lastest stable release. Some messages in their IMAP folders are producing the following error. The current command did not succeed. The mail server responded: Error in IMAP command UID: Invalid BODY[_] parameter: Missing '>' in '<16384.-14781>'. it occurs on the same messages in the users email client but happens randomly, it does not stop you from viewing the message, its just pops up with this error. I'm current using IMAP over SSL and using mbox not maildir for IMAP Any ideas or hep would be great as I'd rather not have to roll back out to UW-IMAP Gabe

How old version are you using? :) Or had you changed the default? i had indeed changed the default, thinking that it would be a nice feature to turn on. when the problem first surfaced, i immediately thought of this option. however, since the problem was that applemail wasn't seing the new mail, and this was an option to notify the client that there *was* new mail, i guess common sense got the better of me and i forgot this was something i had changed... > > mailbox_idle_check_interval = 0 > > This shouldn't matter because OSX Mail doesn't use IDLE.

[Dovecot] corrupted inboxes

Hi all, Two users on our system have recently had trouble reading their inbox, and it seems to be a result of their inbox getting corrupted. In the most recent case, their Mailbox file (in /home/eric/Mailbox in this case), has the following as the first line: cnw.igmg-- Here's a piece of the logs below... if you look for "eric", there's a successfully delivery, followed a bit later by a POP attempt by "eric" that returns that the Mailbox isn't in mbox format.

[Dovecot] Authentication to Active Directory
by Chris Wakelin 15 Mar '05

15 Mar '05

Has anybody managed to have Dovecot authenticate to Microsoft Active Directory? I've tried to get it to work using LDAP and the following settings dovecot.conf: userdb = ldap /etc/dovecot-ldap.conf passdb = ldap /etc/dovecot-ldap.conf dovecot-ldap.conf: hosts = rdg-home.ad.rdg.ac.uk dn = cn=bind-user,cn=users,dc=rdg-home,dc=ad,dc=rdg,dc=ac,dc=uk dnpass = XXXXX ldap_version = 2 base = dc=rdg-home,dc=ad,dc=rdg,dc=ac,dc=uk user_filter = (sAMAccountName=%u) pass_filter = (sAMAccountName=%u) I've also tried things like "(&(objectClass=sAMACcountName)(cn=%u))" to no avail. It appears to bind properly, but never finds the account, so login fails. I've had Active Directory authentication working with Squid and with Cyrus SASL/IMAP.

[Dovecot] Drac and Dovecot, almost there ...
by Jon Shoberg 15 Mar '05

15 Mar '05

I have dracd and dovecot up and running and trying to get the two connected. I'm using the FC3 rpms from callimg yum install. I've downloaded the drac patch from http://dovecot.org/patches/drac.c and compiled it with both gcc -Wall -W -shared -fPIC -DHAVE_CONFIG_H -I$dovecot -I$dovecot/src/lib drac.c -o drac.so -ldrac and gcc -Wall -W -shared -fPIC -DHAVE_CONFIG_H -I$dovecot -I$dovecot/src/lib drac.c -o drac.so I get no warnings or errors on the compiling to drac.so. In the conf file I have imap_use_modules = yes imap_modules = /usr/lib/dovecot/imap However, I don't see the module being called. Is there a way to tell. The dracd database (/etc/mail/dracd.db) is not being updated via testing with the drac utilities. Thoughts? Ideas? Below is output from a strace ...

[Dovecot] Dovecot 64-bit and Pine error
by Remy Zandwijk 15 Mar '05

15 Mar '05

Hi all, I compiled a 64-bit Dovecot stable (13-03-2005) version on a Solaris 9 box with gcc 3.4.2. OpenSSL and libiconv are compiled 64-bit also. The configure I use: export CPPFLAGS="-m64 -I/var/tmp/openssl/include" export LDFLAGS="-m64 -L/var/tmp/openssl/lib" ./configure \ --prefix=/opt/dovecot \ --sysconfdir=/etc/opt/dovecot \ --disable-shared \ --with-libiconv-prefix=/var/tmp/iconv \ --without-passwd-file \ --without-shadow \ --without-vpopmail \ --without-static-userdb \ --with-ssl=openssl \ --with-ssldir=/etc/opt/dovecot/cert \ --without-pop3d Dovecot is running fine, all email clients are running fine, except for Pine (4.62). When saving a mail to another IMAP mailbox, Pine report an error message and the logfile shows: Mar 14 16:33:28 tbox dovecot: [ID 107833 local1.error] IMAP(tstud1): utime(/var/tmp/var_mailstore/ t/tstud1/.Drafts/tmp/1110814408.P2681Q0M979308.tbox) failed: Value too large for defined data type Compiling Dovecot in 32-bit, saving mail within Pine is doing just fine. I guess this is caused by maildir-save.c, line 219. Is this a bug in Solaris or Dovecot? -Remy

[Dovecot] dovecot 0.99 + apple mail.app
by sean finney 14 Mar '05

14 Mar '05

hello all, first off, a success story. after much testing and preperation, we've switched from uw-imap to dovecot. i am not kidding when i say that we have experienced an order of magnitude decrease in server load (previously load peaks were 40-60, now they are 3-4). so, suffice to say that the mail admins here are very happy :) one problem that has come up though is particular to apple's mail.app. when a client recieves a new message, they aren't notified that it's arrived, and often even when pressing "check for new mail" they don't see it come in. however, if they move from one mailbox to another, and then back, it shows up. it also shows up if thtey completely quit out of the program and start it back up. i'm going to try and get a packet dump of this to see if i can find out what's happening in the conversation, but figured in the meantime i'd put my feelers out to see if anyone else is having this problem. thanks, sean

[Dovecot] dovecot-stable mbox weirdness
by Matt Howard 14 Mar '05

14 Mar '05

I just tested dovecot-stable from 2005-03-08 and 03-12 and saw the following behavior. All of my mbox folders show is the first message's header. None of the files were truncated (whew, saves a restore). I had 0.99.12.1 installed before this, and just switched back to 0.99.14. Both 0.99.x versions work fine. I removed all of the index files to see if there was a hiccup there, with no effect. System is Slackware 10.0. My package was built with this: http://tinyurl.com/6l2vv

[Dovecot] aha! (was apple mail vs. v0.99)
by sean finney 14 Mar '05

14 Mar '05

it seems that when you say "check for new mail" in apple mail, it sends a NOOP to the imap server to get the response. in uw, the conversation is something like: 25 NOOP 25 OK NOOP completed 26 NOOP * 2796 EXISTS * 7 RECENT 26 OK NOOP completed however, with dovecot, if it has already notified the client that new mail has arrived, it will look something like: * 24 EXISTS * 2 RECENT 22 NOOP 22 OK NOOP completed. 23 NOOP 23 OK NOOP completed. (the counts are different because these are seperate accounts) so evidently, apple mail is too stupid to realize to read info from the server unless it asked for it... so now that i think i have a short-term fix (disabling notification for new mail server-side), i can breathe a sigh of relief. for a long-term fix, would it be possible to have the server always notify the client of new mail after a NOOP? thanks, sean

[Dovecot] Authentication error after authentication query (for Eudora 5.2 on Mac)
by Tim Alberts 14 Mar '05

14 Mar '05

Greetings all, I'm a new user of Dovecot and want to say thanks for the great software. I am having a problem at the moment. I run a heterogeneous network with windows and Mac clients logging into a Fedora Linux 2 box running sendmail and previously UW-IMAP, but now Dovecot. I am using strictly pop3, plain authentication with mbox format. Every computer in the network is working fine with this sytem, except 1. A mac running Eurdora mail 5.2. It gives me an Authentication error every time it tries to get mail. I telnet into the server and when I skip the AUTH process and just log in, the server works fine as follows: [talberts@localhost ~]$ telnet mail.inside.msi 110 Trying 192.168.0.3... Connected to mail.inside.msi (192.168.0.3). Escape character is '^]'. +OK dovecot ready. user tdazey +OK pass ****** +OK Logged in. quit +OK Logging out. Connection closed by foreign host. [talberts@localhost ~]$ However, when I do the following session: [talberts@localhost ~]$ telnet mail.inside.msi 110 Trying 192.168.0.3... Connected to mail.inside.msi (192.168.0.3). Escape character is '^]'. +OK dovecot ready. auth cram_md5 -ERR Unsupported authentication mechanism. auth login -ERR Unsupported authentication mechanism. auth plain + user tdazey -ERR Authentication failed. user tdazey +OK pass ****** +OK Logged in. quit +OK Logging out. Connection closed by foreign host. [talberts@localhost ~]$ I don't need any authentication except plain. However, when the client queries the settings, it fails the login. I tried this on multiple accounts with the same results. What do I do to fix this?

[Dovecot] Dovecot, pam and OpenLDAP
by Rune Hamnvik 14 Mar '05

14 Mar '05

Hello We have a Dovecot installation using only pop3 where auth data is stored in OpenLDAP and accessed using pam. With Fedora 2 everything has worked fine, but when we upgraded to Fedora 3 we started to get problems. After a while a lot of dovecot processes existed, and error messages was logged in maillog telling that the processes was too old. Then some error messages telling about memory leak was logged. Our /etc/pam.d/dovecot looks like this: #%PAM-1.0 auth required pam_nologin.so auth required pam_stack.so service=system-auth account required pam_stack.so service=system-auth session required pam_stack.so service=system-auth Any idea what is happening?

I've always had to drop my IMAP connection and reconnect to recognize changes I've made on the server side. A kill -1 to dovecot will only reload the server process and the login auth processes...it won't kill your already established IMAP connection, which as far as I can tell, keeps using old settings. If you are having that many problems, delete all of your subscriptions files and dovecot caches and start from scratch. I've had to do it a few times to get things to work as expected.

[Dovecot] Restrict Imap access
by Sergiu Zaharia 13 Mar '05

13 Mar '05

Hello. I need to restrict access to IMAP ports to a few users, so that all users can use POP3 and just a few of them will be able to access IMAP. I use secure connections POP3s and IMAPs. Is it possible? Also... When I connect to the Dovecot server using Outlook (IMAPs) I get a Warning message,something like: "The server you are connectiing to uses a non verified protection certificate. A chain of certificates ...so on ( I can't translate :) ) Continue using the server? " How can I fix that warning? Thanks

Do you even see the mailbox list? Maybe kmail got somehow confused and recreating the IMAP account entirely would be easiest way to fix it.

[Dovecot] pop before smtp with 'exact' and 'exim4'
by Jools Smyth 13 Mar '05

13 Mar '05

Hello, I just thought I would write this in case its useful to anyone. I've used dovecot for a while, as its so easy to set up, its fast and it and just "works". I recently wanted to be able to send via my server after pop3s authentication. I'm also running debian (testing) which utilises exim4 by default. I found no information about how to do it with this combination of software so went about sorting it out myself. First I got exact : (a pop before smtp daemon) http://adju.st/dist/exact/ After compiling and installing i edited its /usr/local/etc/exact-servers.conf It doesn't support dovecot's log format out of the box, so i created a regular expression entry for it. <server dovecot> order username,address match (Login): (.*) \[(.*)\] </server> I then edited its main configuration, (/usr/local/etc/exact.conf) changing only the user its running on (default mail/mail) to Debian-exim/mail. (so that the state file it creates can be read fine by exim4) I also changed the mail log ownership so that group mail can read them, /usr/local/var/state/exact to drwxr-sr-x 2 Debian-exim mail 1024 Mar 13 16:39 exact and /usr/local/var/run/exact to drwxr-sr-x 2 Debian-exim mail 1024 Mar 12 21:54 exact Exact's exim documentation is not for the most recent version, so I had to locate the correct line to modify. I went into the exim4 configuration files. I use the debian split format configuration. In the file /etc/exim4/conf.d/acl/30_exim4-config_check_rcpt there is a line near the bottom which reads accept hosts = +relay_from_hosts I changed this to accept hosts = +relay_from_hosts : net-lsearch;/usr/local/var/state/exact/rela y I then just set exact to and start/stop in /etc/init.d/exim4 thats all!

I am getting errors from dovecot when trying to search, in large Maildir folders. The folder has 40454 messages and is 371MB in size. The email client is squirrelmail 1.4.3, running on FreeBSD-current. I've had this problem before, and i posted a message here. The author said he would fix this, but it seem the problem is still not resolved. This is the error i get: --- ERROR : Connection dropped by imap-server.

[Dovecot] Logging options
by Joebstl Thomas 12 Mar '05

12 Mar '05

Hi, is it possible to configure dovecot's logging so it logs stuff like "User x logged in from IP/Host y and had z new messages" like I'm used from qpopper? That immensely helps when debugging PEBKAC issues. Enabling auth_verbose isnt really helpfull since a failed login generates 4 lines, some even without a pid - so it's a bit hard guessing which log entry belongs to which login attempt or even writing a script which checks for those. Regards, Thomas

[Dovecot] dovecot test62 vs test64
by akolasny＠jhu.edu 12 Mar '05

12 Mar '05

Greetings: I've been using Dovecot 1.0-test62. It has been working well. I tried to upgrade to 1.0-test64 but users could not authenticate. Both versions I compiled with: ./configure --with-ssl=openssl; make; make install They compiled and installed fine. The /usr/local/etc/dovecot.conf needed to be modified due to the new syntax. 1.0-test64 with the new dovecot.conf didn't work. I'm using imaps. The error related to not being able to authenticate. I reinstalled test62 with the original dovecot.conf and everything worked fine again. My config files look like: dovecot.conf-test62 looks like: base_dir = /var/run/dovecot/ protocols = imap imaps pop3 pop3s ssl_disable = no ssl_cert_file = /usr/share/ssl/certs/dovecot.pem ssl_key_file = /usr/share/ssl/private/dovecot.pem disable_plaintext_auth = yes login_dir = /var/run/dovecot-login login = imap login = pop3 mail_extra_groups = mail default_mail_env = mbox:~/mail/:INBOX=/var/spool/mail/%u auth = default auth_mechanisms = plain auth_userdb = passwd auth_passdb = pam auth_user = root dovecot.conf-test64 looks like: base_dir = /var/run/dovecot/ protocols = imap imaps ssl_disable = no ssl_cert_file = /usr/share/ssl/certs/dovecot.pem ssl_key_file = /usr/share/ssl/private/dovecot.pem disable_plaintext_auth = yes login_dir = /var/run/dovecot/login default_mail_env = mbox:~/mail/:INBOX=/var/spool/mail/%u protocol imap { } protocol pop3 { } auth default { mechanisms = plain passdb pam { } userdb passwd { } user = root } What am I doing wrong? Am I missing something in the 1.0-test64 config file? Your comments or suggestions are greatly appreciated. Thanks, Anthony

hey folks, i have a little more info on this problem... about my setup: i have a mail server running dovecot imap on port 143 and uw imap on 8143. all mail is delivered directly to ~/mbox. what happens: when mail talks to dovecot, every time you check new mail, it re-downloads the entire mailbox. new mail does not show up in the inbox, even after it can be confirmed delivered (via mutt on the server). the really wierd part: even though the message doesn't show up in the list of messages in the inbox, the number of new messages floating above the dock icon (and next to the combined "In" box) *does* go up! wtf?? if you switch between mailboxes, or select "rebuild mailbox", the new message shows up of course both involve resynching the entire mailbox again... my first thought was that this was some kind of wierd application bug, but i'm not so sure. with uw-imap, when you select check new mail it does not re-download the entire mailbox, but the new message does not reliably show up until you switch from one message to another in your inbox. so it seems like there's *some* kind of difference between the two servers... and here come the questions: what would cause apple mail to always download all messages from dovecot but not from uw-imap? i found the following link, is it still relevant? http://lists.freebsd.org/pipermail/freebsd-questions/2004-April/044513.html is this something that might be resolved with 1.0-stable? is there something specific i should look for in protocol dumps? would compacting mailboxes have any effect on this? anyway, thanks to everyone who's helped so far... sean
