[Dovecot] Spaces removed from subjects in FETCH response
by Kenneth Porter 06 Oct '04

06 Oct '04

I'm using SpamAssassin to tag spam and prefix the spam score to the subject line. To make the scores sort properly in the client's message list, I pad the score with spaces to right-align it. It looks like dovecot-0.99.10.9-1.FC3.2 is frustrating this by stripping the excess spaces from the subject before reporting it in FETCH responses. Here's an actual subject line: Subject: (SPAM? 6.9) Urgent Response !! Note the multiple spaces before the "6.9". Here's the matching FETCH command and reply, as reported in Mulberry's IMAP.log (just the relevant message is shown here): A00035 FETCH 1507:1524 (FLAGS RFC822.SIZE UID INTERNALDATE ENVELOPE BODYSTRUCTURE) * 1517 FETCH (UID 1557 FLAGS (\Seen) INTERNALDATE "02-Oct-2004 12:24:40 -0700" RFC822.SIZE 6263 BODYSTRUCTURE (("text" "plain" ("charset" "us-ascii") NIL NIL "8bit" 1168 24 NIL ("inline" NIL) NIL)("message" "rfc822" ("x-spam-type" "original") NIL "original message before SpamAssassin" "8bit" 3855 ("Sat, 02 Oct 2004 13:52:28 -0400" "Urgent Response !!"

[Dovecot] 'Connection dropped by imap-server' when doing searches in
by Mike Jakubik 05 Oct '04

05 Oct '04

Hi, It seems that on larger folders (32k emails) searching fails with the following error under squirrelmail 1.4.3a. (The server continues to work, as the hard drive stays on for a bit after the error is displayed) --- Search Results ERROR: ERROR : Connection dropped by imap-server. Query: SEARCH CHARSET ISO-8859-1 ALL SUBJECT {9} 5.3-BETA7 SUBJECT {9} available --- Oddly enough, when searching for just '5.3-BETA7' instead of '5.3-BETA7 available' the search completes OK. I can search with multiple strings on smaller (3k) folders however. Thanks.

[Dovecot] dovecot-auth
by Piviul 05 Oct '04

Hi, I'm a new list member, I’m a not an English native speaking (so, please forgive any error you can find in this mail) and I'm trying to install Dovecot in Debian Woody. I've installed the Dovecot package from backports and I’m trying to configure it to get the credential authentication from an LDAP backend. This is the configuration process summary I’ve done; if you need some configuration file I can post it with great pleasure. In LDAP I’ve created the user cn=dovecot,ou=DSA,dc=flanet,dc=org, I’ve configured this user to have read access to the userPassword field in slapd.conf (the other parameter such as uid, directoryHome… can be read as anonymous), I’ve configured the dovecot-ldap.conf to bind using the “cn=dovecot,ou=DSA,dc=flanet,dc=org” and I set the *auth_userdb* and *auth_passdb* of dovecot.conf to *ldap /path/to/dovecot-ldap.conf*. When I’m trying to start dovecot in the mail.err log file I can find > Oct 5 11:13:29 PDC-SMB dovecot-auth: LDAP: ldap_simple_bind_s() failed (dn cn=dovecot,ou=DSA,dc=flanet,dc=org): Invalid credentials Is the problem that the ldap-password is stored in SSHA crypted mode and in *dnpass* I've inserted it in plaintext? Or more in general, someone can help me to find where I wrong and how can I try to solve it? Piviul

[Dovecot] timeout when retrieving folder list w/ Evolution 2.0?
by leon breedt 05 Oct '04

05 Oct '04

hi, i have a problem with some maildir folders, where Evolution times out when retrieving the header list. It only happens with one particular folder, but i can't seem to find a pattern behind it. The amount of headers it does manage to retrieve varies, from between 3% to 50%. Its not a particularly large folder either (only 520 messages). The error message I get from Evolution is "Server response ended too soon". I did an Ethereal trace, and the closest IMAP command before the failure is: FLAGS (\Answered \Seen) RFC822.SIZE xxx INTERNALDATE "xxx" UID nnn)\r\n its a different UID value that fails each time though. after this response from the server, it seems to get through the message header (not sure if the entire message header was sent back). i'll keep this folder around as a test case. any ideas on where to start debugging? i'm fairly familiar with C and gdb. leon

[Dovecot] Dovecot and fcntl errors
by Eric Joe 05 Oct '04

05 Oct '04

Hello, I am new to the list and after searching the net for a solution to this problem, I have yet to find it. Maybe someone here can help. I had been using Dovecot that came with FC2 for about 1200 POP3 and IMAP mail accounts. At random times (1-5 days) an imap process would run the cpu usage up to 99% on one of my cpus (Running SMP P3-866) and hang. That process was unkillable and only a reboot would fix the problem. If I let it go, eventually it would lock up the server completely. I am seeing this error in my /var/log/maillog <snip> Oct 4 08:23:21 ns2 imap(editorial): Timeout while waiting for release of exclusive fcntl() lock for index file /home/editorial/mail/.imap/INBOX/.imap.index Oct 4 23:00:10 ns2 imap(jimar5573): Timeout while waiting for release of exclusive fcntl() lock for index file /home/jimar5573/mail/.imap/INBOX/.imap.index Oct 4 23:02:10 ns2 imap(jimar5573): Timeout while waiting for release of exclusive fcntl() lock for index file /home/jimar5573/mail/.imap/INBOX/.imap.index Oct 4 23:04:10 ns2 imap(jimar5573): Timeout while waiting for release of exclusive fcntl() lock for index file /home/jimar5573/mail/.imap/INBOX/.imap.index </snip> I have since upgrade (built from source) Dovecot 0.99.11 and have been running for 2 days without a hung process or lockup, but I still see these errors in the maillog. Can anyone suggest a fix? Regards Eric

[Dovecot] Dovecot/IMP Bug with RFC822.SIZE and BODYSTRUCTURE
by Ryan Hulsker 05 Oct '04

05 Oct '04

Ok, I have narrowed my IMP/Dovecot attachment problem down to what I think is a bug in Dovecot. The test that follow are performed on 0.99.11. When you download an attachment in IMP it uses the php function imap_fetchbody() which contacts the IMAP server and retrieves just the mime chunk you are looking for. It does this by first fetching some information about the email, and then grabs the specific chunk you are looking for in a second request. The first request looks like this. "FETCH 258 (ENVELOPE BODY.PEEK[HEADER.FIELDS (Path Message-ID Newsgroups Followup-To References)] BODYSTRUCTURE INTERNALDATE RFC822.SIZE FLAGS)" Dovecot responds properly on all parts of this request except for the BODYSTRUCTURE portion which gets returned as this. "BODYSTRUCTURE ("text" "plain" NIL NIL NIL "7bit" 0 0 NIL NIL NIL)" This causes the imap_fetchbody() funtion to freak out and not do the 2nd request, and it returns 0 bytes. If I manually try "FETCH 258 (BODYSTRUCTURE)" Dovecot returns the expected data properly. I figured there must be an interaction between the BODYSTRUCTURE fetch and one of the other items that are requested, so I tried them all and narrowed it down to this. FETCH 258 (BODYSTRUCTURE) <- works OK FETCH 258 (BODYSTRUCTURE RFC822.SIZE) <- BODYSTRUCTURE reply is wrong. I have been surfing through the dovecot source looking for a way to fix or work around this, but I am only a mediocre C coder. Can anyone enlighten me? Ryan Hulsker

[Dovecot] trouble accessing mbox folders with simultaneous logins
by 2 m＠le / Jonathan Salomon 04 Oct '04

04 Oct '04

Hi all! I have setup dovecot (RPM) on a Fedora Core 2 machine using LDAP for authentication. It all seems to work pretty well, except for simultaneous logins. I am using mbox files to store the mail as follows (from /etc/dovecot.conf): default_mail_env = mbox:~/.mail/:INBOX=/var/mail/%u:INDEX=MEMORY So the INBOX file is stored in /var/mail, other mailfolders are stored in the users home directory in the .mail folder. Because the /home directory of this machine is mounted from fileserver through NFS, I have set the INDEX=MEMORY options (see http://www.dovecot.org/doc/nfs.txt) As said before I am getting some problems when using simultaneous logins for the same mail account (for instance when multiple users that work on a specific project want to share a mail account containing all the mail about the project in addition to their private account). The client used is Microsoft Outlook and besides some outlook specific problems, it also gives these errors (translated from Dutch) when many users are simultaneously logged in to the same account: 'Your server reported that a UID does not comply with the IMAP standard, which signifies an error on the server.' 'The UID of a message is unexpectedly deleted. This signifies an error on the server.' I am not sure where to look... I assume a problem with the index files? Does NFS cause the problem? Will this be fixed if I switch to maildirs? I would be grateful for any tips on the subject!

Re: [Dovecot] trouble accessing mbox folders with simultaneous logins
by Michael Cosby 04 Oct '04

04 Oct '04

I can help you narrow the problem down a bit. I'm assuming you're using 1.0-test45 or 46, in which case I see the same problem using mbox, index files stored on disk and no NFS. I access my mail via pine and chatter email (an imap client for the palm). While I've not seen any errors that specifically say UID, the client for the palm will occasionally reload messages from a few days back thinking they're new, which eventually crashes the client when the count of mail it should be loading doesn't match what it actually got (the palm client's in beta, too :) ). I solved the problem by moving back to the 0.99 series, which other than performance issues works just fine for me. - Michael ------------------- In response to: Hi all!

[Dovecot] Slow squirrelmail login/IMAP CPU 80%
by rusecure＠rogers.com 04 Oct '04

04 Oct '04

I've been having a problem with Dovecot on Fedora Core 2 with SquirrelMail on the same system. When ever I login through SquirrelMail the imap process consumes around 80% of my CPU and the login takes forever (about 10 minutes). 1 Once I do manage to login, everything is fine and can even log out and back in without issue. Has anyone encountered this? Thanks, Nelson

[Dovecot] evolution and received by header
by Dan Stromberg 03 Oct '04

03 Oct '04

Evolution has a nice feature where it can sort messages by the most recent received-by date, instead of the Date: header. This is nice, because then if something gets stuck on a server somewhere in the world for a couple of days, it shows up at the end of your mail list, instead of way back where you might miss it. However, when using dovecot with evo, if I sort of received by instead of date, it takes forever. I assume this is because date is indexed, and received by is not. So the natural question becomes, is there a way of getting dovecot to index received by? TIA.

[Dovecot] child <pid> (imap) killed with signal 6

Linux <hostname> 2.6.8-1.541 #1 Wed Sep 1 18:01:46 EDT 2004 x86_64 x86_64 x86_64 GNU/Linux dovecot-0.99.11-1.FC3.3 I'm struggling with some new problems after an update from the devel tree of Fedora. Have been using dovecot since FC1 test-something, and latest working was couple of updates after FC3t2 (2.91 + devel updates). Tried downgrading with no luck, and can't figure out what's wrong. Setup is very standard Fedora, all defaults I guess, using postfix and Maildirs, and dovecot for imap access. What happens is when logging in and authenticated ok, the connection is dropped. To illustrate I've connected directly and showing the (verbose) output: (commands) [xxx@xxxxxxx ~]$ telnet localhost imap Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. * OK dovecot ready. x login imtest <password> x OK Logged in. Connection closed by foreign host.

So problem is for all accounts, both new, old and empty. Would be guessing some sort of permissions problem but should be running mostly as root in default mode? And the dovecot user seems to be ok and working, directory permissions are corrected at startup if it's wrong, and so on... I'm not an expert, might be something trivial, but cannot figure it out by myself or Google so mailinglists are next. Let me know if I should send some more information about the system. Thanks, Per-Stian

[Dovecot] Dovecot/IMP attachment problem
by Ryan Hulsker 01 Oct '04

01 Oct '04

I recently installed dovecot in my production environment. This comprises about 60k mailboxes. The system was initially set up with dovecot 0.99.10.7 using maildirs. I have been using perdition to handle redirection during the process of converting from wu-imap. Last week it was brought to my attention that our webmail interface (horde/imp) is no longer allowing people to download attachments. Everything appears to work fine, however the downloaded files are 0 bytes in size. I built a test box with the latest horde/imp/php combination and that failed to solve the problem. Today I upgraded dovecot on one of our mail servers to 0.99.11 and that seems to have had no effect. I was hoping that the BODY and BODYSTRUCTURE changes from 99.10.8 would have fixed this. I am wondering if anyone has encountered these problems? Is this a dovecot bug? Due to the fact that I am still in transition mode using perdition I am in the unique position where I can basically hit two identical mailboxes, one in wu-imap and the other in dovecot just by using a different username. I have done this, and have ethereal traces if anyone is interested in helping me out with this. Ryan Hulsker

Well, the attachments do exist in the mailbox, and sending attachments is no problem. Retrieving attachments through OE->dovecot works, OE->wu-imap works, IMP->wu-imap works, however the combination of IMP->dovecot seems to cause a problem. I have a feeling that IMP is using a different method of retrieving the attachments than OE does, and there is probably something IMP does not like about dovecots responses. I will go through my ethereal traces and see if I can piece together what is going on in more detail. Ryan Hulsker

Now, when I start the process, either by clicking the start button on the MS Managemente Console or by cygrunsrv -S dovecot, i get to error dialogs saying that the program needs cygcrypt-0.dll and cygwin1.dll.

I'm not sure what kind of API PHP provides for c-client. I know it's commonly used for building IMAP webmails, but Dovecot doesn't have any IMAP client code and maybe never will.

[Dovecot] pgsql and default_pass_scheme
by eL gino 29 Sep '04

29 Sep '04

Hello list, I am running Dovecot 1.0-test46 on FreeBSD with PostgreSQL as backend, runs _very_ nice, but i can not set "default_pass_scheme = CRYPT" (only PLAIN) for PostgreSQL Auth in dovecot-pgsql.conf. I have a valid entry in pg_hba.conf (and reloaded/restarted): "local mail mail crypt" If i replace crypt in pg_hba.conf with md5 it works also with plain in dovecot-pgsql.conf? -- Christian. PS: sorry for my poore english.

[Dovecot] Dovecot 1.0-test45 indexing issues
by dovecot＠spam.turbolink.net 28 Sep '04

28 Sep '04

We're currently on dovecot 0.99.10 with a few modifications (including one very nasty hack for the blank line at the beginning of the mailbox bug). We're using mbox all around. Everything works smoothly but we still ocasionally get corrupt mailboxes and indexes that need to be wiped out. I setup 1.0-test45 on one of our mailservers to start testing it and ran into a few issues. The first one is if I try to use mail_read_mmaped=yes I get this error: Error: POP3(sobo1): file istream-raw-mbox.c: line 410 (istream_raw_mbox_get_body_size): assertion failed: (rstream->mail_size != (uoff_t)-1) for every mailbox. If I switch to mail_read_mmaped=no everything works, but performance is extremely bad. I have a few test mailboxes with about 20k messages and if I toggle a message flag from unread to read, dovecot seems to re-read the entire mailbox up to that message (I saw this with strace). Is this how supposed to work?? I don't see behavior like this on 0.99.10, and on a mailbox with any substantial number of messages it really slows things down. Thanks for any input. - Mike

[Dovecot] Moving mail dirs

28 Sep '04

Hi all, This is probably a silly question, but I have a problem. I've had to move my users maildirs from: maildir:/home/%u/.Maildir To maildir:/data/mail/%u I've updated the MTA to put mail to the correct place and it's working fine. I've also changed the dovecot.conf file and restarted dovecot and I thought that would be all I needed to do. However, the users are getting lots of error messages, and looking in the relevant logs shows lots of entries like: Sep 28 14:03:36 <hostname> imap(<user1>): stat() failed with file /home/<user1>/.Maildir/new: No such file or directory Sep 28 14:03:36 <hostname> imap(<user2>): utime() failed with index file /home/<user2>/.Maildir/.INBOX/.imap.index: No such file or directory (Sorry for changing usernames and hostname, but I'm neurotic about that kind of thing) What have I missed?

[Dovecot] Thunderbird 0.8 - Inbox grayed out and does not update
by Sitapati das 27 Sep '04

27 Sep '04

Hi all, I cannot get Thunderbird 0.8 to work with my dovecot IMAP server. It works fine with my work IMAP account - I'm not sure what they are using. What happens is that folders that I create in Thunderbird or Evolution can only contain subfolders or messages, not a combination of both. Folders which contain subfolders and not messages show up in Thunderbird grayed out. I can expand them and view the subfolders and the messages within those. The Inbox however, also shows up grayed out. When I look inside I can see the messages that were there when I created the IMAP account in Thunderbird, however, no new messages arrive, even after restarting Thunderbird. If I connect with Evolution 1.4 I can read the inbox without a problem. Has anyone seen this? warm regards, Joshua

[Dovecot] Concerned about Dovecot's new NTLM code
by Andrew Bartlett 26 Sep '04

26 Sep '04

I'm pleased to see another project increasing compatibility with windows clients, by the addition of NTLM login support, but I'm a bit worried about a few implementation details, and hope to offer an alternate approach. I mean no disrespect to those who have implemented to the code so far, but I feel that the idea of 'everybody re-implement NTLM' is prone to failure. Firstly, to bugs I've noticed by casual inspection of your implementation: - Unicode support is by 'null padding' - there is no real support for non-ascii characters. - NTLM2 (a negotiated scheme to avoid sending the LM response) is unsupported - NTLMSSP is NDR, not 'C struct pushed to the wire', it needs to be correctly marshaled and unmarshaled. There are other missing features, some of which are rumoured to become mandatory flags in future, but more importantly, because the implementation is standalone, it has no ability to integrate into an NT/Win2k/Samba domain. As part of the Samba team, I have worked with other projects - Squid in particular, to deliver server-side (and client-side) NTLMSSP authentication, without the need to re-implement the NTLMSSP protocol. This is done by a callout to 'ntlm_auth', a Samba 3.0 utility designed for this purpose, which in turn can contact domain controllers, allowing for seamless single sign on. http://samba.org/samba/docs/man/ntlm_auth.1.html I have recently completed reworking mod_ntlm_winbind for a similar purpose, and have patches for cyrus-sasl in my 'lorikeet' subversion repository. These should serve as good examples for the simple fork()/exec() modal that is used, and also show the support for GSS-SPNEGO (aka HTTP Negotiate) that ntlm_auth also provides. http://download.samba.org/ftp/unpacked/lorikeet/trunk/ My hope is that I can tempt a Dovecot developer to take on the challenge of modifying the dovecot to use ntlm_auth, and am most willing to answer any questions (here, by private mail or on the samba-technical list) that you may have on the issue.

[Dovecot] problems with cvs version and vpopmail
by Kristoffer Ek 24 Sep '04

24 Sep '04

Hi, I have tried compiling the latest cvs version of dovecot on my FreeBSD 5.2.1-release box with the ports version of vpopmail: 5.4.3_1. In the configuration file I have two auth paragraphs, one for passwd authentication and one for vpopmail-auth: auth vpopmail { mechanisms = plain userdb = vpopmail passdb = vpopmail user = vpopmail } But the vpopmail dosn'nt work. I got the folowing in the log: Info: auth(vpopmail): vpopmail(stoffer(a)test.ek.dk): unknown user (stoffer(a)test.ek.dk) When I ktrace the dovecot process, it seams that it is trying to access the mysql db, but it ignores the settings in ~vpopmail/etc/vpopmail.mysql If I use the ports version of dovecot it works, but of course without the multiple auth capability since it is version 0.99...

[Dovecot] more verbose debugging with test45
by Kim Culhan 24 Sep '04

Greetings- Is there any way to increase the logging output of dovecot ? I've set auth_verbose and auth_debug = yes The only output is a single line to syslog mail.info: Sep 23 09:01:54 server dovecot: pop3-login: Login: me [ip.is.here.00] test45 doesn't appear to have the --rawlog configuration option There is nothing written to ~/dovecot.rawlog Tried setting ~/dovecot.rawlog mode to 777 Running FreeBSD-5.3 and dovecot-1.0-test45 dovecot is using passwd auth and pop3s for test purposes and appears to be working correctly otherwise The reason I think I need this is that I don't feel comfortable putting this into production as it is a 'black box' at this point, without a little more testing..

[Dovecot] 1.0-test46
by Timo Sirainen 24 Sep '04

24 Sep '04

http://dovecot.org/test/ Most importantly added mbox_lazy_writes option, enabled by default. This makes Dovecot do writes to mbox only with EXPUNGE and CHECK commands and when mailbox is being closed. This is the same behaviour as with UW-IMAP. Especially useful for POP3 where most users just download the mails and delete everything - with this enabled Dovecot doesn't anymore go writing X-UID headers and whatever. Be careful anyway with this release, it seems to be working with me but mbox can get corrupted from simple mistakes. Other important fixes include: - handle UIDVALIDITY changes in mbox correctly - we might have overridden others dotlock files if they were being rapidly recreated with different processes - should fix syncing read-only mboxes (maybe dovecot.org finally stops giving internal errors :) - fixed several other mbox syncing issues which were quite rare without lazy writing - when sending lots of non-mail data to IMAP clients, Dovecot might have lost some of it causing weird problems. With pop3 it crashed with assert instead of losing data.

[Dovecot] Questions about mail process chroots
by Brett Smith 22 Sep '04

22 Sep '04

Greetings, I am configuring a new Dovecot installation, and the way the valid_chroot_dirs and mail_chroot variables affect the mail processes are a bit unclear to me. I was wondering if anyone could provide me with more specific details than the comments in the configuration file do, or maybe even recommend some values given my configuration. We have a Debian GNU/Linux system and a mix of users with shell accounts and users with disabled logins. Both these groups should be handled the same way by Dovecot: auth_userdb is passwd and auth_passdb is pam. The dovecot PAM service will use pam_mysql.so, if that matters. Mail is in mbox format (we have too many sticklers who are set in their ways, unfortunately); I'm thinking default_mail_env should be mbox:~/Mail/:INBOX=/var/mail/%u. So, if I understand correctly, (a) I should set chroots on the mail processes, since some of our users don't have real shell accounts, and (b) those processes will need access to /var/mail and home directories under /home. So my best guess is that I should set the chroot variables like this: valid_chroot_dirs = /var/mail:/home mail_chroot = /var/mail I'm not sure about this though, for a number of reasons. Do I need to even chroot at all, or do I misunderstand the comments? If I do need to chroot, the comments about valid_chroot_dirs warn very strongly that the chroot dirs should not be writeable by users. /home itself isn't writeable by users, but obviously their home directories are. Is listing /home also vulnerable to exploits? If it is, what would a good solution be? What's the meaning of /./ in mail_chroot? The comments about it, unfortunately, make no sense at all to me. It says that /home/./user is the same as /home, but if that's completely true, why wouldn't I just say mail_chroot = /home? I even looked into the source and it still wasn't really clear to me. Thanks in advance for any help you can offer, -- -- Brett Smith

[Dovecot] Lost messages with Mozilla and dovecot 0.99.x
by John Peacock 22 Sep '04

22 Sep '04

I have just moved our corporate e-mail over to qmail/dovecot and am very happy with the performance. However, I have had two reports of messages going missing which may or may not be directly related to Dovecot. I was able to observe this in action this morning: 1) I got the user out of their e-mail client (Mozilla 1.7.2) and forced an email to be delivered. It showed up in Maildir/new. 2) I had the user log in using our webmail (Squirrelmail) and the message was visible to the client (and correctly moved to Maildir/cur). 3) The user then logged in using the Mozilla mail client and not only was the message not visible in the client, it was no longer on the disk! 4) This was completely repeatable, even if I deleted the .INBOX/index files and forced dovecot to rebuild. For the moment I am thinking this is a client problem, but I thought I'd mention it just in case it rang a bell with someone. I wound up installing 0.99.11 just for grins (I just moved these people to the new server and don't want to risk 1.00-test yet). I'm also going to look at whatever debugging messages are available in dovecot; it would be useful to see a log of all imap transactions, not just login, so I could confirm that it is the client process requesting that the files be deleted and not somethink with dovecot itself (or some hardware failure).

http://dovecot.org/test/ I think I finally fixed the hangs some people have been having when downloading mails. For some reason I could never reproduce this problem with Linux or Solaris, but with OpenBSD it happened immediately. Stupid problem with marking output buffer empty if it was full and write() returned EAGAIN. Other changes include: - LDAP initialization crashed - fixed some compiler warnings and some issues with 64bit systems - fixed some memory leaks What bugs are there left?
