[Dovecot] mbox and maildir
by Shane Kerschtien 15 Oct '04

15 Oct '04

Is it possible to mix maildir and mbox formats with dovecot? For example, I would like ~/mail to be in maildir format yet keep the inbox (/var/mail/%u) in mbox format. If so, how may I go about this? Or am I stuck not being able to create subdirectories in ~/mail? Cheers, Shane

[Dovecot] my future with dovecot (?any recipe?)
by NORA CENTRAL 14 Oct '04

Hallo I am very impressed from this howto's: 1) Postfix-Cyrus-Web-cyradm-HOWTO (mysql) http://www.delouw.ch/linux/postfix.phtml 2) Pop-Toaster using Qmail-Vmailmgr-Courier-SquirrelMail http://qvcs-guide.sourceforge.net/ (this work for me) I hope to build anything like above, but with Dovecot: [Postfix-tls-smtpauth-Dovecot-Mailadmin*-MySQL-SquirrelMail-https] Postgresql is ok for me with email-admin must be exist. I dos not like qmail & Co, ldap... and cyrus is to big for me. I found tousand mosaiks in internet to build any email server... mostly bound to debian, suse, redhat what i not use and i prefer all piece self compile and package for Archlinux or Slackware. My problem is the choice of ingredients and later to assemble it. Community need howto's like above two and some working full complete recipe to self build. I hope to find a recipe for dovecot+postfix+tls+ssl+smtpauth and [postgresql|mysql|firebird|metakit|any.other.db] nora

[Dovecot] not enough information in the syslog
by Mikhail Teterin 14 Oct '04

14 Oct '04

Although I set `auth_debug = yes' in the dovecot.conf, the line about my uid being too low was never logged by the server. Neither KMail nor Mozilla showed me the rejection message, that dovecot was giving them. I had to ktrace the process to see it and adjust first_valid_uid down. Yours, -mi

[Dovecot] painfully slow uploads
by Mikhail Teterin 14 Oct '04

14 Oct '04

I have several mail accounts, but collect all spam e-mail in the spam mailbox on one of them. After switching to dovecot (from imap-uw) I notice a very slow speed of bulk transfers and a very high CPU utilization by the dovecot's imap process during it -- sustained 62% of my server's Pentium2 @266MHz. Never saw such effects under imap-uw... My client is KMail (despite the awfull quality of its latest release). Hope, this helps. Yours, -mi

[Dovecot] assertion failed and debugging dovecot
by Doug Luce 14 Oct '04

14 Oct '04

I'm getting this error on a particular message in my Maildir: Oct 11 21:59:48 aurora dovecot: IMAP(doug): file ostream-file.c: line 646 (_send_istream): assertion failed: (instream->v_offset <= in_size) To me, more import than the question "why is this happening" is "how can I debug this?" Attaching gdb to the running imap process doesn't give me access to the proper function names to set up breakpoints and get a stack trace. Can someone with the experience give a quick how-to on debugging functions deep in dovecot? Thanks, Doug

[Dovecot] what exactly does outlook-idle workaround?
by Jonathan Salomon 13 Oct '04

13 Oct '04

Hi, Can anyone tell me what the 'client_workarounds = outlook-idle' directive exactly does? I have enabled it in my /etc/dovecot.conf, but the problem that I think it should solve still exsits. That is that after being IDLE for more than half an hour Dovecot will disconnect Outlook but Outlook never connects back. Therefore users receive new mail, but they don't get notified unless they press send/receive. So what does the workaround do? And how can I solve the problem? Thanks! Jonathan

[Dovecot] SASL
by alan premselaar 13 Oct '04

13 Oct '04

I've been browsing the wiki and thru my mail-list archives but haven't found an answer. does/can dovecot 0.99.x support authenticating with a SASL database? I'll be setting up a new mail server for my offices using Sendmail/MIMEDefang/ClamAV/etc with dovecot as the IMAP server. I'm not familiar at all with LDAP. I know that sendmail will authenticate to a SASL database and it's fairly easy to setup. My goal is that I can support "real" users (actual user accounts) but allow their mail passwords to be different than their login passwords, and changeable via some sort of CGI interface. (I also have 2 weeks to accomplish this) any assistance is appreciated alan

[Dovecot] Does dovecot support subfolders in Outlook (and in general)
by AWC Maillists 12 Oct '04

12 Oct '04

Ok, I am playing around with dovecot and things are running relatively smoothly. I am using Outlook as that is what the client uses for Email. I can copy messages to and from the IMAP folder. I can create folders from the root directory fine. My question is this. I have folders like this: IMAPServer --Inbox --Trash --WorkToDo Now when I try and create a subfolder in "WordToDo" I get an error message "Unable to create the folder. The server responded: 'Mailbox doesn't allow inferior mailboxes' When I try to create a subfolder in "Inbox" I get an error message "Unable to create the folder. The folder 'Inbox' cannot contains subfolders..." So is this a limitation of Dovecot? Another problem with Outlook? Or do I have some configuration problem on my end? Thanks. --- Charles PS: My first impressions of dovecot are very positive. It is a much cleaner and, so far, easier to handle IMAP server than the heavyweight UW & Cyrus IMAP servers. Congrats on a impressive program.

Not yet. But I guess I should one day add support for it. Most SASL mechanisms support it directly without a kludgy username. I'm not sure about the configuration though. For passwd-file I guess there could be just one global flag which means that the user has access to everyone's mails. For LDAP and SQL I guess the pass_filter/password_query could have a few new %vars to describe the other user. Or maybe there needs to be a separate filter/query for that case. Hmm. Do you want the poweruser to have access to all mailboxes, or just for the one domain? What passdb are you using?

[Dovecot] Detecting unused accounts
by Ben Beuchler 12 Oct '04

12 Oct '04

I'm looking for a way to figure out which accounts have not been logged in to in over n days. It occurs to me that, perhaps, the way to do this would be to look at the mtime on one of the dovecot-maintained files, like 'dovecot-uidlist'. Is there a particular file that would be modified on (almost) every login, whether it be via POP or IMAP? -Ben -- Ben Beuchler There is no spoon. insyte(a)emt-p.org -- The Matrix

[Dovecot] Enable outlook-idle workaround.

11 Oct '04

I just recently discovered dovecot. I am evaluating the program and several clients uses Outlook/Outlook Express. In the clients issues section of dovecot.org is says "You should enable outlook-idle workaround" Ok, maybe I am missing something very obvious here but I can not find any documentation on how to implement the outlook-idle workaround. Can anyone point me to an article or something with more details on this issue? Thanks in advance.

[Dovecot] 1.0-test47
by Timo Sirainen 11 Oct '04

11 Oct '04

http://dovecot.org/test/ Been a while since last release. Still seems there are some mbox problems, but I haven't been able to break anything for last few days. I guess it's stable enough. At least more stable than test46 which crashed quite often when expunging. - pretty much rewrote "index extension" support. it's now possible to add extensions to headers and to message records. it's possible to resize them. I'll probably use it soon to change mbox code to use 32bit offsets and automatically grow to 64bit offsets once mbox grows over 4GB (well, yes, rare, but.. :) - login_greeting and login_greeting_capability settings - auth_verbose is even more verbose - mbox fixes/optimizations - other fixes/additions

[Dovecot] dovecot and (no) new incomming mail - migration from wu-imapd
by Götz Reinicke 09 Oct '04

09 Oct '04

Hi, I recently installed dovecot 0.99 on a fedora core 1 Server which used the wu-imap-server. dovecot starts and I can subscribe to my old imapfolders, but if I send mails to my account, this new mail arent downloaded. If I quit Mozilla and restart Mozilla, the recently send mails are in my inbox. We use also a webmailsystem, so I could verify that the mails are in the inbox without relogging in. This phenome is not showing up by all my imap accounts. I'm testing with mozilla 1.7.3 and 1.8a4 on a mac os x 10.3.5 Client. The Inbox-folder for the "defect" account is showing in italic and grey ghosted (in the folder list), the folder in the working account is normal. A user using Netscape 7.1 on a Windows XP Client has also no Problems....

[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 !!"

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?

[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! 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!

[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] Public folders / namespace documentation
by Keith Edmunds 04 Oct '04

04 Oct '04

Does Dovecot support public folders? I thought it may do via namespaces, but having searched the Wiki and the documentation, I can't find how namespaces are defined. I've probably not looked in the right place - any pointers? Thanks, Keith

[Dovecot] using %d in passdb

hi, i'd like to seperate the password file for seperate virtual domains into seperate files. i tried specifying: passdb = passwd-file /etc/exim_incoming/local/accounts/pwdb/%d but i get an error message that it couldn't open the particular file, and then Dovecot shuts down. is there a way to do lazy-lookups? or, would i be required to write a little helper program and have Dovecot connect to its socket to do auth? leon

[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
by Per-Stian Vatne 02 Oct '04

02 Oct '04

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. [xxx@xxxxxxx ~]$ (log) dovecot-auth: Oct 02 14:59:32 Info: Login process 7 connected dovecot-auth: Oct 02 14:59:32 Info: Login process 7 sent handshake: PID 10816 imap(imtest): Oct 02 14:59:40 Panic: Trying to allocate 0 bytes imap-login: Oct 02 14:59:40 Info: Login: imtest [::ffff:127.0.0.1] dovecot-auth: Oct 02 14:59:40 Info: Login process 6 disconnected dovecot: Oct 02 14:59:40 Error: child 10818 (imap) killed with signal 6 I've looked around on the web for this error, can't find anything except problems reading index files, so the imtest user is a newly created user which have received one single text message, Maildir is created ok and can be read using mutt or something. 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

Sorry guys I have to ask this one more time. I really need an answer. Have any of you been able to make Dovecot work on Cygwin? Do any of you know about anybody who have had any success on it? I repeat, I'm eager searching for an answer. If it is possible I'll contact the person who achieved it. If it is not possible yet, I'm gonna have to switch. Thanks once more.

[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

[Dovecot] Dovecot on Cygwin
by espino＠infomed.sld.cu 30 Sep '04

30 Sep '04

I'mt trying to make Dovecot run on Cygwin. I managed to make it compile and register as a service on Windows XP. I had a problem with setrlimit, but I disabled the process size limitation in the config file. 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 have both of those libraries on the system but the program doesn't seem to see them. Do any of you have a clue about this? Thanks. ------------------------------------------------- Este mensaje fue enviado usando el servicio de correo en web de Infomed http://webmail.sld.cu

They are more or less separated already, but I don't know how useful it would be to create a separate library distribution from them. That is what takes most of the space in Dovecot distribution anyway..

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.
