[Dovecot] 1.0-test65
by Timo Sirainen 17 Mar '05

17 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
by Nicholas Riley 17 Mar '05

17 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. There have been several of these messages: dovecot: Feb 21 11:40:06 Error: IMAP(njr): mbox sync: UID inserted in the middle of mailbox /usr/home/njriley/mail/lists/trac (5308 > 1151) dovecot: Feb 21 22:57:13 Error: IMAP(njr): mbox sync: UID inserted in the middle of mailbox /usr/home/njriley/mail/lists/trac (6458 > 1151) dovecot: Feb 22 08:37:03 Error: IMAP(njr): mbox sync: UID inserted in the middle of mailbox /usr/home/njriley/mail/lists/reportlab-users (5162 > 3812) Others: dovecot: Feb 22 11:44:17 Error: IMAP(njr): file mbox-sync-parse.c: line 221 (parse_x_uid): assertion failed: (!ctx->sync_ctx->sync_restart) dovecot: Feb 22 11:44:17 Error: child 19931 (imap) killed with signal 6 dovecot: Feb 25 06:26:09 Error: IMAP(kbode): file istream-raw-mbox.c: line 383 (istream_raw_mbox_get_body_size): assertion failed: (rstream->body_offset != (uoff_t)-1) dovecot: Feb 25 06:26:09 Error: child 83423 (imap) killed with signal 6 (I think this refers to the mailbox that was corrupted) dovecot: Feb 25 12:30:40 Error: IMAP(sachs): Transaction log file /home/sachs/Mail/.imap/INBOX/dovecot.index.log: invalid indexid (1109356120 != 1108933119) dovecot: Feb 25 12:30:40 Error: IMAP(sachs): Corrupted transaction log file /home/sachs/Mail/.imap/INBOX/dovecot.index.log: Extension record update update without intro prefix dovecot: Feb 25 12:30:41 Error: IMAP(sachs): Transaction log file /home/sachs/Mail/.imap/INBOX/dovecot.index.log: marked corrupted dovecot: Feb 25 12:39:34 Error: IMAP(sachs): Transaction log file /home/sachs/Mail/.imap/INBOX/dovecot.index.log: invalid indexid (1109356120 != 1108933119) dovecot: Feb 25 12:39:34 Error: IMAP(sachs): Lost transaction log file /home/sachs/Mail/.imap/INBOX/dovecot.index.log seq 2 dovecot: Feb 25 12:39:41 Error: IMAP(sachs): Transaction log file /home/sachs/Mail/.imap/INBOX/dovecot.index.log: invalid indexid (1108933119 != 1109356120) I am currently reinstalling 0.99.14, but it would be nice to be able to switch to a 1.0-derived version again - we have to run two copies of 0.99.x to get what we want. If there is any additional testing I can do to help fix these problems, please let me know. Thanks, -- Nicholas Riley <njriley(a)uiuc.edu> | 4111 Siebel Center Department of Computer Science | 201 N.

[Dovecot] Problems with Outlook 2002 SP3 & Dovecot 0.99.13 Redux
by Md 16 Mar '05

16 Mar '05

Hi, I posted this question a while back and didn't get much response. Since then, I've done a bit more experimenting and wonder if someone can help me move forward towards resolution. The orignal question... > I'm running Dovecot0.99.13 on Fedora Core 3 and things work fine when using either > Thunderbird 1.0 or Outlook Express as IMAP clients. Outlook (2002 SP3) on the other hand > runs incredibly slowly, or just outright hangs. I've discovered that if I delete and recrete .../Maildir in the user account such that the directory exists but is empty, then outlook seems to behave. If on the other-hand, I try to create a folder, with outlook, outlook will hang and the folder won't be created. If I create the folder with another client and then go back to using outlook, outlook will hang. I've taken some network traces and have annotated them here...

[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. Regards, Robin

[Dovecot] dovecot-auth hangs with IO leak
by Alan Tam 16 Mar '05

16 Mar '05

Hi dovecot, I am using the debian dovecot packages on a system running LDAP. 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.

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.

[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 ... I don't see /usr/lib/dovecot/imap/drac.so being opened ... execve("/usr/sbin/dovecot", ["/usr/sbin/dovecot"], [/* 20 vars */]) = 0 uname({sys="Linux", node="masra.org", ...}) = 0 brk(0) = 0x8c85000

[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 15 Mar '05

15 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 14 Mar '05

14 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!

[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.

[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

[Dovecot] more info on apple mail vs dovecot 0.99
by sean finney 11 Mar '05

11 Mar '05

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

If your provider has a firewall for its customers that disallows access to certain ports (such as 25 and 80), you simply can not receive email (by SMTP). Perhaps FastMail will allow you to specify a specific port, but I doubt it.

[Dovecot] 1.0-test64
by Timo Sirainen 10 Mar '05

10 Mar '05

http://dovecot.org/test/ Possibly fixes the mail-cache-transaction assert. Passdb and userdb configuration changed. New format is: passdb sql { args = /etc/dovecot-sql.conf } passdb pam { } userdb passwd { } The above would first try to authenticate from SQL database, if it failed because user wasn't found, or password was wrong, it would then try PAM. The same is done for userdbs. I'll probably do some other configuration file changes still before v1.0. I'm also thinking about having a separate config process which can read the actual configuration from files or sql.

[Dovecot] dovecot patch for TCB auth
by Thomas Hummel 08 Mar '05

08 Mar '05

Hi, I'm writing to you on behalf of the Pasteur Institute's (Paris, France) IT team. We're currently using dovecot-0.99.10.5_2 on a FreeBSD 5.3. We're planning to upgrade to dovecot-1.x with an openLDAP user and password database and patch it at the same time to include some authentication feature we're using : Since most of our user currently don't use dovecot at all and still authenticate on a DEC alpha running OSF1 [digital unix] V5.1 732, an authentication profile is maintained for each of them on the system. This user profile is kept in the protected password database, accessible only to trusted programs acting on behalf of the trusted computing base (TCB). Some TCB fields are useful to us so we're planning to use their LDAP attibute equivalents and we wrote a custom LDAP shema that includes those which were missing from the standard openLDAP distribution [see details below]. So we're planning (in fact are about to) patch dovecot-1.x in order to take those LDAP attribute (matching the TCB field of interest to us) into account. To do so, we wrote some documentation (still in a draft state) to extend our understanding of dovecot architecture and authentication process. Of course, we're going to give it (patch + doc) back to you and make it freely available. But we'd like to know if you : - were already working on such a patch or planning to do so - were interested, once done (by us or you) to include it into the official release, since it could interest some other person who runs digital unix with TCB authentication Thanks -- Thomas Hummel | Institut Pasteur, Paris, France <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau -------- Here are some details about which attribute we're planning to use and their TCB equivalents uidNumber ~ u_id uid ~ u_name userPassword ~ u_pwd shadowLastChange ~ u_succhg shadowExpire ~ u_expdate shadowMax ~ u_life shadowWarning ~ u_exp [ shadowWarning = u_life - u_exp] plus the one we wrote : maxTries ~ u_maxtries [ maximum number of consecutive unsuccessful login attempts to the account that are permitted until the account is disabled ] numUnsucLog ~ u_numunsuclog [ number of unsuccessful login attempts to the account.

[Dovecot] mail-cache-transaction.c error

[Dovecot] Upgrade to new server question
by John Peacock 08 Mar '05

08 Mar '05

I'm vainly trying to get a new server ready to become the default mail server. We have a SAN, so I don't need to move the mailboxes (I can mount the same partition from both machines), but the question is what version of dovecot to load. I'm assuming that I cannot run both 0.99.14 and 1.00.x on the same maildirs (the indexes differ?). However, is it safe for me to mount the same maildirs from two different boxes?

[Dovecot] 1.0-test63 released
by Timo Sirainen 07 Mar '05

07 Mar '05

http://dovecot.org/test/ A new test release for a change. Fixed several problems with indexes, especially related to transaction log rotating (pretty easy to find bugs when you set them to be rotated every 5 seconds and keep bombing the same mailbox with 10 test clients). Please report both new and old bugs. The changes might have fixed lots of different randomly occuring problems. The most important bugfixes were also done to dovecot-stable. The tarball is already updated. Looking at changelog, there seems to be: - Don't crash if client disconnects in the middle of APPEND - LDAP and static passdbs can return "extra parameters" (http://wiki.dovecot.org/AuthSpecials) now. Only SQL did before. - Added "nice" extra parameter for userdb to set imap/pop3 process's priority - RPA/SQL passdb patches from Andrey - Major rearrangements (again) to auth code: - Blocking passdbs (SQL) now create auth worker processes to do the actual blocking work. auth_worker_max_count setting specifies the maximum number of these processes to create. PAM and checkpassword code should be fixed to use this method as well. - Fallback to using expired records from auth cache if database lookups fail. - multiple auth setting blocks still not working - Transaction logs are now rotated when they're over 128kB and created (not updated as before) more than 5 minutes ago. So with high traffic mailboxes the log file shouldn't grow forever anymore.. - other fixes and cleanups

[Dovecot] Too many open files, etc.
by Martin Preen 07 Mar '05

07 Mar '05

Hello, a few days ago I switched out UW-server installation to dovecot 0.99.14 (Solaris 9). There were a few client issues, but mostly the migration was ok. But I have still some questions/problems: +) dovecot-auth: ... PAM: pipe() failed: Too many open files I increased the max. number of open files. Is this normal behaviour, that more than 512 open files are needed ? +) we're using mbox on NFS and index files on local disks. When building the index files for the first time, it takes (of course) a long time for large folders. But we have these users, and this will happen sometimes. Is there a way to improve performance ? +) in general dovecot saves a lot of NFS-bandwidth compared to UW-imap. Thats what I was looking for. But there also seems to be a problem with large inboxes (> 10 MB) and/or large attachments. Is this right ? One user currently gets this error from Pine when accessing a large attachment: MAIL FOLDER "INBOX" CLOSED DUE TO ACCESS ERROR. AFAIK this error is related to some timeout problem. Has anyone seen this (and a solution for it) ? Thanks.

[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: )?

[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
by Andrew Hutchings 06 Mar '05

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/
