[Dovecot] imap over ssh won't work
by Taco Witte 13 Jan '07

13 Jan '07

Hi, Using version 1.0.rc15 I'm trying to let Evolution connect with IMAP over SSH. When run from the command line, this is what I get: ssh host dovecot --exec-mail imap * BAD [ALERT] imap binary must not be started from inetd, use imap-login instead. ssh host MAIL=/root/Maildir/ /usr/local/libexec/dovecot/imap * BAD [ALERT] imap binary must not be started from inetd, use imap-login instead. When I run the same commands directly on "host", I do get a PREAUTH prompt (Logged in as root) and when I look around I find exactly the same syntaxis. Does anybody have a clue why it doesn't work? Thanks in advance and kind regards, Taco

[Dovecot] IMAP folder watching plugin request
by Jonathan Stewart 13 Jan '07

13 Jan '07

Hello Timo and list, I'm pretty sure this has been asked before but would it be possible for a generic folder watching plugin to be distributed with Dovecot? My intention for this is to be able to integrate a spam filter into dovecot. Filtering would be performed on delivery and spam put into a spam folder and then if mail was moved into or out of the folder the filter could be retrained. I am willing to help with any testing of course. Thanks, Jonathan

Re: [Dovecot] Configuring Dovecot for use with Active Directory
by Phil Anslemo 13 Jan '07

Here's my updated dovecot-ldap.conf file. I made some slight changes after starting dovecot and receiving errors. hosts = 192.168.0.240:389 #uris = dn = cn=<BINDUSER>,ou=IT,ou=Central Office,dc=<DOMAIN>,dc=local dnpass = <PASSWORD> #sasl_bind = no #sasl_mech = #sasl_realm = #sasl_authz_id = auth_bind = yes #auth_bind_userdn = ldap_version = 3 base = dc=<DOMAIN>, dc=local deref = never scope = subtree user_filter = (&(objectClass=user)(sAMAccountName=%n)) #pass_attrs = uid=user #pass_attrs = uid=user,userPassword=password,homeDirectory=userdb_home,uidNumber=userdb_uid,gidNumber=userdb_gid pass_filter = (&(objectClass=user)(sAMAccountName=%n)) #default_pass_scheme = CRYPT user_global_uid = 101 user_global_gid = 101 Now that I've cleaned up most of the problems, the next issue I'm having is actually authenticating the users from dovecot through ldap in active directory. When it attempts to authenticate, dovecot hangs and then timesout. The only thing I can think of is ldap needs to send the password to Active Directory in a format it can understand. Has anyone run into this?

[Dovecot] Weird indexing problem between Thunderbird and Dovecot
by Mario Nigrovic-rvvk40 13 Jan '07

13 Jan '07

Folks - I just ran across this problem; not sure how it originally happened. I noticed that Thunderbird was displaying the wrong message body when I selected a message. I tried several actions to clean up the problem (stopping dovecot and thunderbird, removing all .thunderbird/pref/ImapMail cache data, removing all dovecot index and uidlist files), to no avail. Then I noticed that somehow a core file had made it into my main inbox. I surmise that dovecot saw it as a legitimate email but thunderbird refused to count it (or some permutation thereof). (The core file had been renamed "core,2u" IIRC). Anyway, removing the offending file and (again) all cache files seems to have solved the problem. Just FYI. -- Mario

[Dovecot] help with deleted segment of email when connecting Outlook?
by Lisa Rau 12 Jan '07

12 Jan '07

This group was so helpful last time I am hoping someone can HELP! We have qmail / dovecot running IMAP and a user who had all their email in their non-Outlook client (Thunderbird?). We installed Outlook 2003 and configured it with IMAP and all their email EXCEPT a three week block showed up. The three week block of email is not on their desktop and even worse, isn't on the server / in qmail - its totally gone. Does anyone have any idea of why or how this would have occured? And even better - is there any hope we could ever find this email (its not on a backup)? Hopefully, Lisa

[Dovecot] RC16 is a lot slower that RC7
by Marc Perkel 11 Jan '07

11 Jan '07

I tried RC16 from RC7 and like other releases since RC7 it is significantly slower. I'm still trying to figure out why. But I have again switched back. Do new version take up a lot more ram perhaps? I'm running with a gig of ram, and I'm running a few other apps. It's not a fast computer, just an old 754 pin semptron. But the point is that RC7 runs a lot faster than RC16.

After a while authentication freezes. On the LDAP server (openldap v2.2.28) I see countless log entries such as: " slapd[24721]: connection_input: conn=1134942 deferring operation: binding". Dovecot show I tried to increase various dovecot and openldap limits without success. Until the problem is solved, I use Dovecot with getpwnam (/etc/passwd) + pamldap which works always OK. Could anybody please verify that direct LDAP userdb_prefetch, passdb, auth_bind work ok with openldap under heavy stress? Is it possible that multiple concurrent LDAP bind requests and searches under different LDAP credentials through the very same TCP connection produce some kind of spourious problem?

[Dovecot] [sfs: dovecot-auth file descriptor usage]
by Steven F Siirila 10 Jan '07

10 Jan '07

I am re-posting this message from last Friday, as I have seen no replies. It is critical that we address this problem, since until then we cannot put more than a few hundred users on our server. If Dovecot-auth TRULY needs to keep open a file descriptor for every single login session, we will have to start looking at alternatives. In short: Help! ----- Forwarded message from Steven F Siirila <sfs> ----- Date: Fri, 5 Jan 2007 13:55:38 -0600 From: Steven F Siirila <sfs> To: dovecot(a)dovecot.org Subject: dovecot-auth file descriptor usage User-Agent: Mutt/1.4.2.1i In dovecot-auth (rc15) we experienced problems when the file descriptors reached 256 (due to a Solaris fdopen() call described previously). The issue was that there was one file descriptor being used for every imap-login and pop3-login process (in our environment of SSL-only that means one for every active IMAP and POP connection). Mods were made (and appear in rc16) to close out the descriptor in question after using it during authentication (as I understand it). However, I am still seeing plenty of file descriptors left open in rc16 (one per session). For example, on a Solaris 9 server with 9 IMAP connections open here is an lsof excerpt of dovecot-auth: dovecot-a 26071 root 7u unix 105,136 0t79 3190 /devices/pseudo/tl@0:ticots->/var/opt/dovecot/run/dovecot/login/default (0x3000d084250) dovecot-a 26071 root 8u unix 105,140 0t80 3190 /devices/pseudo/tl@0:ticots->/var/opt/dovecot/run/dovecot/login/default (0x3c9c4227b68) dovecot-a 26071 root 9u unix 105,149 0t79 3190 /devices/pseudo/tl@0:ticots->/var/opt/dovecot/run/dovecot/login/default (0x3cbaa7680b8) dovecot-a 26071 root 10u unix 105,266 0t79 3190 /devices/pseudo/tl@0:ticots->/var/opt/dovecot/run/dovecot/login/default (0x3cbaa765d48) dovecot-a 26071 root 11u unix 105,160 0t79 3190 /devices/pseudo/tl@0:ticots->/var/opt/dovecot/run/dovecot/login/default (0x3cbaa7667e0) dovecot-a 26071 root 12u unix 105,255 0t79 3190 /devices/pseudo/tl@0:ticots->/var/opt/dovecot/run/dovecot/login/default (0x3cbaa769288) dovecot-a 26071 root 13r DOOR 265,0 0t0 50 /var/run (swap) (door to nscd[7752]) dovecot-a 26071 root 14u unix 105,258 0t79 3190 /devices/pseudo/tl@0:ticots->/var/opt/dovecot/run/dovecot/login/default (0x30002dc4008) dovecot-a 26071 root 15u unix 105,282 0t80 3190 /devices/pseudo/tl@0:ticots->/var/opt/dovecot/run/dovecot/login/default (0x30003185738) dovecot-a 26071 root 16u unix 105,141 0t80 3190 /devices/pseudo/tl@0:ticots->/var/opt/dovecot/run/dovecot/login/default (0x30003185ac8) With the modification made, shouldn't these no longer accumulate? -- Steven F.

[Dovecot] pre-1.0.rc6 / index file problems? try this
by Timo Sirainen 10 Jan '07

10 Jan '07

People who have had "duplicate header extension" and whatever other random index file corruption problems, please see if this fixes anything: http://dovecot.org/list/dovecot-cvs/2006-December/007315.html The change is also in the latest nightly snapshot (http://dovecot.org/ nightly/dovecot-latest.tar.gz). You could in general treat the latest snapshot as "pretty much the same as the 1.0.rc16 release", so some testing for it would be nice. I've updated autotools that were used to build the snapshot, does anyone have problems with compiling the snapshot? I'm going to build the 1.0rc16 release using the same autotools. rc16 has several changes intended to make Mac OS X's HFS+ happy. This is mostly because currently the only computer I have is a Powerbook. I'll get a new Linux machine in a couple of weeks hopefully. I've still about 50 unread/possibly unanswered mails. I'll try to get to them soon. Here's a list of all the important changes: * IMAP: When trying to fetch an already expunged message, Dovecot used to just disconnect client. Now it instead replies with dummy NIL data. * Priority numbers in plugin names have changed. If you're installing from source, you should delete the existing plugin files before installing the new ones, otherwise you'll get errors. * Maildir: We're using rename() to move files from tmp/ to new/ now. See http://wiki.dovecot.org/MailboxFormat/Maildir -> "Issues with the specification" for reasoning why this is safe. This makes saving mails faster, and also makes Dovecot usable with Mac OS X's HFS+ (after you also set dotlock_use_excl=yes, see below). + Added dotlock_use_excl setting. If enabled, dotlocks are created directly using O_EXCL flag, instead of by creating a temporary file which is hardlinked. O_EXCL is faster, but may not work with NFS. + If Dovecot crashes with Linux or Solaris, it'll log a "Raw backtrace". It's worse than gdb's backtrace, but better than nothing. + Added maildir_copy_preserve_filename=yes setting. + Added a lazy-expunge plugin to allow users to unexpunge their mails. + maildir quota: Added ignore setting to maildir quota, which allows ignoring quota in Trash mailbox. + dict quota: If dictionary doesn't yet contain the quota, calculate it by going through all the mails in all the mailboxes. + login_log_format_elements: Added %a=local port and %b=remote port - Doing a STATUS command for a selected mailbox (not a recommended IMAP client behavior) caused Dovecot to sync the mailbox silently. This could have lost eg. EXPUNGE events from clients, causing them to use wrong sequence numbers. - deliver was treating boolean settings set to "no" as if they were "yes" (they were supposed to be commented out for "no") - Running "dovecot" with -a or -n option while Dovecot was running deleted all authentication sockets, which caused all the future logins to fail. - maildir: RENAME and DELETE didn't touch control directory if it was different from maildir or index dir. - We treated internal userdb lookup errors as "user unknown" errors. In such situations this caused deliver to think the user didn't exist and the mail get bounced. - pam: Setting cache_key crashed - shared maildir: dovecot-keywords file's mode wasn't taken from dovecot-shared file. - dovecotpw wasn't working with PowerPC

[Dovecot] Dovecot's deliver trouble (...probably bug?)
by Serge D 10 Jan '07

10 Jan '07

Hello everybody! I am a Linux admin trying to move my mail system based on qmail to the software which is more spam-protected: exim4 + dovecot-1.0rc15 + pgsql . I've downloaded and rebuild dovecot from src.rpm (for fc4). During the testing stage I've discovered two troubles: 1) the problem with deliver (...I'm not sure it's a really bug). Here is relevant part of my /var/log/messages : ------- Jan 3 10:40:37 serge deliver(serge(a)test.net): auth input: serge(a)test.net Jan 3 10:40:37 serge deliver(serge(a)test.net): auth input: home=/var/spool/mail/test.net/serge/ Jan 3 10:40:37 serge deliver(serge(a)test.net): auth input: uid=500 Jan 3 10:40:37 serge deliver(serge(a)test.net): auth input: gid=12 Jan 3 10:40:37 serge deliver(serge(a)test.net): setuid(500) failed: Operation not permitted ------- -- my system is fc4 based Linux. uid/gid are according to /etc/dovecot-sql.conf : user_query = SELECT maildir AS home, 500 AS uid, 12 AS gid FROM mailbox WHERE username = '%n@%d' AND active='1' I was trying to chown 500.12 /var/spool/mail -R , chmod u+s ...etc, but it does not helps. Please, help. I don't want another MDA, people adviced me dovecot as good and well tested solution. I have already spent about two work days to configure and test it... 2) Because of mentioned above problem deliver generates a bounce message for exim, and here is a bug with e-mail in the header. It was taken "as is" from the queue of Exim -- have a look at "Return-path:", "envelope-from" and "Sender:" Because of these errors exim can not deliver the message back to sender. It freezes it, ...trying again, ...freezes ... etc... -------------------------------------------------- 1H252L-0004jZ-F3-D This message was created automatically by mail delivery software. A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed: serge(a)test.net local delivery failed ------ This is a copy of the message, including all the headers. ------ Return-path: <"testuser(a)test.net"@test.net> Received: from serge.lc.test.net ([10.0.0.5]) by serge.lc.test.net with esmtpa (Exim 4.62) (envelope-from <"testuser(a)test.net"@test.net>) id 1H252K-0004jT-U5 for serge(a)test.net; Wed, 03 Jan 2007 14:16:05 +0200 Message-ID: <459B9E84.9070607(a)test.net> Date: Wed, 03 Jan 2007 14:16:04 +0200 From: test uset <testuser(a)test.net> User-Agent: Thunderbird 1.5 (X11/20060119) MIME-Version: 1.0 To: serge(a)test.net Subject: =?KOI8-R?Q?=D4=C5=D3=D4_=D0=D2=CF=C8=CF=D6=C4=C5=CE=C9=D1?= Content-Type: text/plain; charset=KOI8-R; format=flowed Content-Transfer-Encoding: 8bit Sender: "testuser(a)test.net"@test.net Test message body. ------------------------------------ Here is an original message from e-mail client ( just to make sure that it was made proper way): ------------------------------------ > From - Wed Jan 03 18:18:54 2007 X-Mozilla-Status: 0001 X-Mozilla-Status2: 00800000 Message-ID: <459BD76D.4090903(a)test.net> Date: Wed, 03 Jan 2007 18:18:53 +0200 From: test uset <testuser(a)test.net> User-Agent: Thunderbird 1.5 (X11/20060119) MIME-Version: 1.0 To: serge(a)test.net Subject: =?KOI8-R?Q?=D4=C5=D3=D4_=D0=D2=CF=C8=CF=D6=C4=C5=CE=C9=D1?= Content-Type: text/plain; charset=KOI8-R; format=flowed Content-Transfer-Encoding: 8bit Test message body. ---------------------------------------------------------- As for POP3 with dovecot, it seems working OK. Dovecot generates mail directories according to the user data returned by SQL, and creates index files proper way - everything with given uid.gid = 500.12 ... If you will need some extra piece of information, or my configs or logs -- please feel free to ask for it. Any kind of help: advices, URLs, patches, etc.., are welcome. I badly need to bring up this new system as soon as possible. Thank you in advance. Best regards, Serge www.cis.by

[Dovecot] deliver rewrites envelop-sender
by Ralf Becker 10 Jan '07

10 Jan '07

Hello, we are currently using sendmail, procmail, uwimap and qpopper. We are planing to replace uwimap and qpopper with dovecot. Which seems to be a very good idea :-) But: Sendmail and Procmail will not be replaced. Now I've realized that deliver rewrites existing "From <....> ..." header lines to ">From <...> ..." and adds it's own "From "-line. Example: -------- My procmailrc end with :0 | deliver -d beckerr Mails are deliver to my INBOX, but * From beckerr(a)fh-trier.de Sun Jan 07 17:37:43 2007 * Received: ... * From: ... is rewritten to * From MAILER-DAEMON Sun Jan 07 17:37:44 2007 * > From beckerr(a)fh-trier.de Sun Jan 07 17:37:43 2007 * Received: ... * From: ... Is there a (simple) way to prevent deliver from doing so? OR In case "-f <envelop sender>" is not given, could deliver 1) read the envelop sender address from the "From <...>" line, 2) remove the line and 3) add it's own using the formally extracted sender address? This sounds best for me and would cover the problem most effective... BTW: I've found the "dovecot deliver patch for procmail" and it looks really good (http://dovecot.org/pipermail/dovecot/2006-July/014656.html) but it seems to me, that the "From " line problem is solved by optionally removing the whole line, so deliver would use it's own default "From MAILER-DAEMON "-line ... and this in fact the problem Regards, Ralf -- ______________________________________________________________________ Dipl.-Inform.

[Dovecot] Disable TLS on port 143?
by Jackie Hunt 10 Jan '07

10 Jan '07

Hi all, Is there a way to disable the TLS support provided by Dovecot on port 143? I'd like to run SSL on 993, so as far as I can tell I can't use ssl_disable, since the will disable SSL. I'm looking for the equivalent of an ssl_disable_tls setting. Thanks much, Jackie --- Jackie Hunt ACNS Voice: (970) 663-3789 Colorado State University FAX: (970) 491-1958 Fort Collins, CO 80523 Email: jackie.hunt(a)colostate.edu

[Dovecot] [minor] stale auth-worker sockets
by Luigi Rosa 09 Jan '07

09 Jan '07

I was fooling around the /var/run/dovecot directory and I noticed a lot of stale auth-worker.xxxxx sockets, probably left there by unexpected termination of old versions of Dovecot. Just to know who does what, have I to clean up the stale sockets, or a future version of Dovecot will get rid of this unused sockets? Ciao, luigi -- / +--[Luigi Rosa]-- \ Syntactic sugar causes cancer of the semi-colons;

[Dovecot] dovecot rc7 assert, core
by Jeff A. Earickson 09 Jan '07

09 Jan '07

Hi, Wow, I haven't had an assert/core in dovecot in a long time. Here goes: Setup: Solaris 10, dovecot built with gcc 4.1.1, imap and imaps only. User's home directory lives on a ZFS filesystem, but I don't think that makes a difference. So does every other user here (>3K). Assert: IMAP(mulepri): file message-body-search.c: line 393 (message_body_search_ctx): assertion failed: (input->v_offset <= part->physical_pos) gdb backtrace and other poking at the core is attached.

Hi, I tried to use DSA certificate today and it did not work very well. Is Dovecot supposed to work only with RSA? -- Vaclav Haisman

[Dovecot] Automatic mail script?
by Andreas Andersson 08 Jan '07

08 Jan '07

Hello! I am setting up a Dovecot mailserver for around 2000 people with: sendmail + dovecot + squirrelmail + spamassassin and some plugins. I have the Imap quota working in mboxes with this quota commands: plugin { # 10MB quota limit quota = dirsize:storage=10240 } It worked good in Squirrelmail, but the person that only use some imap program (outlook, eudora) don't get the info when theirs account will be full of mail. So can someone give me a good script for a automatic mail. I want to send a mail to a user when they are nearly exceeded their limits, so they can start cleaning theirs account. Are this possible or how should I solve this problem? /Andreas

[Dovecot] unable to read mail - file istream-raw-mbox.c: line 499...
by Chris H. 08 Jan '07

08 Jan '07

Greetings all, I (nor anyone else) am suddely unable to read mail. Dovecot dumps the following in it's log: # BEGIN LOG ENTRIES # dovecot: Jan 07 18:15:52 Info: imap-login: Login: user=<username>, method=PLAIN, rip=::1, lip=::1, TLS dovecot: Jan 07 18:15:52 Error: IMAP(username): file istream-raw-mbox.c: line 499 (istream_raw_mbox_get_body_size): assertion failed: (rstream->mail_size != (uoff_t)-1) dovecot: Jan 07 18:15:52 Error: child 1584 (imap) killed with signal 6 # END LOG ENTRIES # NOTE: 'username' represents the users name at that time. The users subscribed to folders all show up. But no mail is visable. Dovecot is leaving username.lock files in /var/mail as well. It doesn't do this on my other servers running dovecot. They are using older versions of dovecot tho. Does anyone know what might be causing these problems? Relavent info follows: Dovecot version: 1.0.r15 OS: freebsd-5.5 Thank you for all your time and consideration. -- panic: kernel trap (ignored) ----------------------------------------------------------------- FreeBSD 5.4-RELEASE-p12 (SMP - 900x2) Tue Mar 7 19:37:23 PST 2006 /////////////////////////////////////////////////////////////////
