[Dovecot] dovecot-1.0-test8 / nfs / maildir / flags issues
by Maikel Verheijen 14 May '04

14 May '04

Hi List, While (bluntly) testing the prerelease version of dovecot on our mailfarm (just for the webmail imap) we noticed some small problems: - While our OLD dovecot/imap drove the load to a maximum of 1 over a day after running, the new dovecot/imap pushes it easily to 20. This is mainly due to a LOT more disk activity. This is probably caused by the fact we a) use indexes on disk and b) there are no indexes left. I hope this will smooth out when most of the indexes are made. - We notice some very strange "delete" flag things in our IMP webmail system (working on a test environment to be more specific). The problem is that if you mark some messages "deleted", a lot of messages that do NOT have "deleted" flag are also in the deleted list. Since nothing changed on the webmail, it must be in the way dovecot responds different in the new version on certain requests. - In the dotlocking code, it seems that dovecot uses time() for it's internal locktime, and uses stat() to see if the file-time of the lock is different. Since we use nfs there might be a time-difference on the file creation and time() when our nfs gets "busy". This happens a lot when the indexes are created for multiple users at the same time resulting in a lot of: May 12 08:57:44 mf1 dovecot[3763]: imap(user(a)domain.tld): Our dotlock file /var/mail/mounted/d/do/domain.tld/user/Maildir/.INBOX/ dovecot.index.log.lock was modified (1084345063 vs 1084345062), assuming it wasn't overridden I am not completely sure if this interrupts imap traffic. I think this MIGHT be solved by storing a stat() time as the locktime instead of a time(), but this might be intentional. - I patched dovecot to report its pid in syslog messages, in order to find the "killed by signal X" where X are mostly 11 and 6 processes. The pids reported do not show up in the rest of the log file, so these may be "disconnected" sessions? It seems that the "old" version has the same problem, and nobody really complained it was broken, so this isn't a big issue. To clarify our setup: We use multiple mail-frontends running dovecot that are load-balanced by a cisco load-balancer. We mount our mailstores from an active-active backend cluster, both nodes export a big partition, and take over the job of the other in case of a problem. This seems to go pretty smooth. Our users are stored in a pgsql database. In our current setup, we run a modified cvs version of dovecot from WAY back, to support nfs. The backdraw is that we can't use the newer dovecot releases, since I couldn't modify the source in the way I did it the first time (with a LOT of help from Timo :P). If anyone has some ideas on where to look and where to test in order to get our problems more clear, I would be very grateful :) Kind regards, Maikel Verheijen Ladot Nederland BV.

[Dovecot] Problem building 1.0-test7 : missing header
by Curtis Maloney 13 May '04

13 May '04

Greetings, I recently rolled out Dovecot in our small (<30 people) company, and have been mightily impressed by the quality, performance and ease of use. I was hoping to use the new versions soon, as I'd like to start using CRAM-MD5 (much more common in mail clients than DIGEST-MD5), but found the 0.99.11 versions too unstable. So, I tried to build last nights CVS snapshot (May 10th), only to have the make break at this point: make[3]: Entering directory `/home/src/dovecot-1.0-test7/src/lib-index' make[3]: *** No rule to make target `mail-index-util.h', needed by `mail-cache.o'. Stop. I know it's not much, but it's a start at giving back a little. Hope it helps. -- Curtis Maloney

[Dovecot] Codepage of folder names
by Petr Tuma 13 May '04

13 May '04

Hi, I have run into a problem configuring DoveCot 0.99 on a Linux server that handles Windows users. The server uses UTF8 on its filesystem but the Outlook IMAP folder names are sent in what looks like CP852. As a result, folder names that use national characters are damaged, which in turn breaks a webmail application running on the same server. A natural solution would be DoveCot translating folder names from CP852 coming across the wire to UTF8 used in filesystem operations, but I did not find any option for that in the configuration. Anybody encountered and solved this problem ? Petr Tuma

[Dovecot] Is Dovecot ready for production use?
by Benjamin J. Weiss 12 May '04

12 May '04

Hi! I'm currently running RH 9 with postfix, uw-imap and MailScanner. I want to install Fedora Core 2 (when it comes out next week) with postfix, dovecot and amavisd. I'm unhappy with the problems I'm having with MailScanner, with the difficulty I've had with authentication as I am currently configured, and want to move to Maildir instead of mbox. That being said, is dovecot stable enough yet for production use? I only have four users on my home linux box, but I personally get around 500 emails a day (that fedora list is *busy*). Thanks, Ben

[Dovecot] php.ini tweak
by Avery 12 May '04

12 May '04

I noticed this is my /etc/php.ini file ---------------------------------------- ; This directive tells PHP whether to declare the argv&argc variables (that ; would contain the GET information). If you don't use these variables, you ; should turn it off for increased performance. register_argc_argv = on ---------------------------------------- I ma trying to squeeze some extra performance out of my email server. If I turn this to off will this cause any problems with SQmail or any of SQmail's plugins. I tried turned this setting to off and everything seems to work fine. I am surprised that no one has asked about this before in this mailing list. Thanks, Avery

[Dovecot] LDAP + passwd
by Paolo Basenghi 12 May '04

Hello, I'm in the process to choose between Courier and Dovecot. I would like to know if it's possible to configure Dovecot in order to use multiple user database (e.g. ldap+passwd) in order to have both virtual user authenticated by LDAP and system user authenticated by system password and with their own home directory. Another question: at http://dovecot.org/doc/dovecot-example.conf there is a configuration example that seems not work with Dovecot 0.99.10.4 It result in a "Fatal: Error in configuration file /etc/dovecot.conf line 391: Missing value".

[Dovecot] Case sensitive user names
by Jeff Graves 11 May '04

11 May '04

Hello list. This is my first post and I hope that I have something useful for people. Using Fedora Core 1 with the stock dovecot-0.99.10 RPM I noticed that user names were case sensitive which was a problem for me since I was attempting to set up winbind authentication which meant that what dovecot thought the homedir was could change depending upon the case the user typed in. Sendmail/procmail always changed the username to lowercase so I needed a way to duplicate this behavior. At any rate, I searched the archives and found Andrew's post from March: http://www.dovecot.org/list/dovecot/2004-March/003067.html - using this as a jumping point and I finally have case insensitive user names (better yet, forced lower case usernames) working for plain-text authentication (eg. dovecot.conf: auth = plain, auth_userdb = passwd, auth_passdb = passwd). It has been tested only on the source RPM from Redhat FC1 and I'm not a C programmer so I have no idea if it will work with other authentication methods or newer versions of software. I've rebuilt the RPMs (source and i386) if anyone's interested and here's the patch for those not using RPMs (it's attached as well): diff -ru dovecot-0.99.10/src/auth/mech-plain.c dovecot-0.99.10.new/src/auth/mech-plain.c --- dovecot-0.99.10/src/auth/mech-plain.c 2003-05-18 08:26:28.000000000 -0400 +++ dovecot-0.99.10.new/src/auth/mech-plain.c 2004-05-11 16:58:30.000000000 -0400 @@ -57,6 +57,7 @@ authenid); } + auth_request->user = str_lcase(auth_request->user); if (!mech_is_valid_username(auth_request->user)) { /* invalid username */ if (verbose) { Thanks, Jeff Graves, MCP Customer Support Engineer Image Source, Inc. 10 Mill Street Bellingham, MA 02019 508.966.5200 - Phone 508.966.5170 - Fax jeff(a)image-src.com - Email

[Dovecot] nfs dotlock issues
by Maikel Verheijen 11 May '04

11 May '04

Hi List, While testing with dovecot-1.0-test8 on our platform, I get al lot of these: May 11 11:42:50 mf1 dovecot: imap(user(a)domain.tld): Our dotlock file /var/mail/mounted/d/do/domain.tld/user/Maildir/.INBOX/ dovecot.index.log.lock was modified (1084268570 vs 1084268875), assuming it wasn't overridden This is probably due to some time-issues on our platform, and the load the backend has. (our backends run in a live environment). Can the dotlock code get the timestamp of the file when the dotlock gets created in order to be able to keep the time in sync? Is there another way to prevent those seconds of time-difference? we run ntpd on both our frondends and our backends. Kind regards, Maikel Verheijen

[Dovecot] 1.0-test7
by Timo Sirainen 10 May '04

10 May '04

http://dovecot.org/test/ Lots of bugfixes related to syncing. There's still some left. Somewhat working mbox support: - combined syncing/rewriting uses much less disk I/O than with older mbox code - expunges aren't working yet - last-uid field in X-IMAPbase header isn't updated - it's currently syncing the whole mbox constantly even if it hasn't changed - it isn't hiding the mbox-specific headers from IMAP clients - if mbox hasn't changed, rewriting could start from the message which requires rewriting instead of syncing the whole mbox - syncing could keep the lock file extra two seconds to make sure if someone changes it the file's mtime changes -> as long as only Dovecot is modifying it, we'll never need to sync the whole mbox -> multi-gigabyte mboxes are still fast! One nice thing about this mbox code is that it isn't exactly mbox-specific. Some people are still using formats which use eg. ^A as separator rather than From-line. Some people are using SMTP-formatted data directly ('.' as mail separator, '..' = normal line begins with '.'). These formats should be pretty easy to implement now as all mbox-specific code is in istream-raw-mbox.c file. I'll probably do that once mbox itself is fully working.

[Dovecot] imap indexing error when moving multiple mails
by Hauke Fath 06 May '04

06 May '04

Hi, I've got an 'interesting' problem with a dovecot 0.99.10.4 setup on NetBSD/i386 1.6ZK. dovecot is serving imap only at the moment, using mbox format mailboxes. '/etc/dovecot.conf' is pretty vanilla - among the modified settings, mail_read_mmaped = yes maildir_check_content_changes = yes mbox_lock = fcntl could be relevant. Anyway - from time to time when I move a bunch of mails ( < 1) from a mailbox to another (or to the trash), the client (I've seen it with Eudora 6 on a Mac, with Mozilla 1.6 and Sylpheed on NetBSD) reports an "internal error" and the maillog shows Mar 25 14:07:33 bounce imap-login: Login: hf [130.83.xxx.yyy] Mar 25 14:07:44 bounce imap(hf): Error indexing mbox file /home/hf/Mail/Leute/Marc Wirth: LF not found where expected Mar 25 14:09:30 bounce imap(hf): Error indexing mbox file /home/hf/Mail/Leute/Marc Wirth: LF not found where expected which, if I retry the operation to another time, does not persist and is not strictly repeatable. I've set the number of allowed concurrent connections to '1' on the client, but that doesn't help. Is there anything obvious that I overlooked, or have I tripped over a genuine bug? hauke -- Hauke Fath /~\ The ASCII Ribbon Campaign Institut für Nachrichtentechnik \ / No HTML/RTF in email TU Darmstadt X No Word docs in email Ruf +49-6151-16-3281, Fax -3778 / \ Respect for open standards

[Dovecot] Dovecot chrooting
by ?a??µp?? ?a?a???t?? 06 May '04

06 May '04

hello all i am new to dovecot and i have a small problem. I use qmail as a pop3 server and dovecot as imap. my rc script is as follows: -----snip----- #!/bin/sh exec env - PATH="/var/qmail/bin:$PATH" \ qmail-start '|preline procmail' splogger qmai -----end----- thus i deliver mails through procmail so all mails are located to /var/spool/mail. The problem exists when i tested chrooting and found it a very good idea to jail all my users.. *but* still qmail delivers mails to the real /var/spool/mail and not to the /home/chrootusers/var/spool/mail so that dovecot can pick them up. Is there any special configuration in dovecot.conf in order to chroot the /var/spool/mail to /home/chrootusers ? some of my conf: login_chroot = yes valid_chroot_dirs = /home/chrootusers mail_chroot = /var/spool/mail default_mail_env = mbox:~/mail/:INBOX=/var/mail/%u PS: tell me if you need more of the dovecot.conf PS2: sorry for my english its not my native

[Dovecot] Envelope From changed - why?
by Tom Alsberg 04 May '04

04 May '04

Hi there. I am evaluating Dovecot as an IMAP server. I noticed on thing which irritates me. When a user saves a message to an IMAP folder with the Dovecot server, the envelope From line is changed to the address of that user, instead of keeping the From line of the original message. How can I have the original envelope From line preserved when saving messages? -- Tom -- Tom Alsberg - certified insane, complete illiterate.

[Dovecot] Maildir files in cur without info
by Christoph Hohmann 04 May '04

04 May '04

Hi, I have tried to use the same Maildir dovecot uses with another program and encountered the problem that Dovecot seems to move files from new to cur in maildir-sync.c::maildir_scan_dir without adding an info part. On the page http://cr.yp.to/proto/maildir.html is written that mails have to be renamed to uniq:info when moved to the cur directory. Could this be a bug in dovecot? -- http://reboot.animeirc.de http://sylpheed-claws.sourceforge.net/

[Dovecot] Dovecot hangs after 2 or 3 days
by Jens Gutzeit 03 May '04

03 May '04

Hi all, We've some problems with our dovecot installation, its the latest stable compiled on a debian woody box. After 2 or 3 days dovecot hangs, no user can login (pop3 and imap), there's nothing in the logs. The client does allways timeout, if I restart dovecot all works well again. It's a box with s.th. around 400 users, we've enough mem free, load is not a problem, it went from 0.9 to 0.1 after migrating from cyrus-imapd, so this doesn't seem to be hardware related.

[Dovecot] 1.0-test1 released
by Timo Sirainen 03 May '04

03 May '04

http://dovecot.org/test/ I couldn't break this with Evolution with a few minutes of testing, so here's the first tarball release based on the new indexing code. Try if you're interested, but don't try it on any real mailboxes, or at least keep backups :) Also note that dovecot-uidlist file format has changed a bit, Dovecot 0.99.x isn't able to read it anymore. Things to do: - mbox code doesn't even compile, so it's disabled - custom flags aren't implemented - recent flags are broken - cache file handling isn't working now, so it's disabled - maildir syncing code isn't as well optimized as it used to be - NFS-safety to indexes (pretty easy)

http://dovecot.org/test/ I still haven't done much real world testing, but I've been thinking about all the potential race conditions a lot since last time and fixed a lot of them. There might still be some.. Changes since -test1: - Locking fixes - A lot more difficult to crash it with corrupted index files - Recent flag works, this time exactly as IMAP RFC says - Maildir syncing fixes - fcntl_lock_disable and mmap_disable settings to make it work with NFS.. almost. Not very well tested and there's a few performance issues left. - mmap_no_write setting to disable mixing write/mmap calls. Required for OpenBSD. Uses slightly more memory. If you can break the indexes, I'd like to know about that. I think they should work pretty well now.

[Dovecot] Timezone of logentries from dovecot
by Lars Skovgaard 29 Apr '04

29 Apr '04

Hi I've been using dovecot for a long time now, and have nothing but praise for it. It's considerably faster than uw-imap, and has been very easy to configure, in spite of my limited knowledge of unix. One thing still botheres me, though, and that's the time of the entries in my logfiles. It seems that dovecot logs it's entries in GMT, while I'm using GMT+1. This is made even worse by the fact that we're now using daylight savings time, which upps the difference to two hours. Here's a couple of lines from my logs to show the difference: Apr 29 14:30:07 misterp mach_kernel: ipfw: 10000 Deny UDP 213.122.19.185:33123 129.142.126.35:137 in via en0 Apr 29 14:30:59 misterp mach_kernel: ipfw: 4000 Accept TCP 80.197.22.210:38518 129.142.126.35:995 in via en0 Apr 29 12:30:59 misterp pop3-login: Login: torben [80.197.22.210] Apr 29 14:32:25 misterp mach_kernel: ipfw: 10000 Deny UDP 195.122.208.191:1066 129.142.126.35:1434 in via en0 I don't know how to fix this, whether it's in dovecot or somewhere in a system-setting. However, all other applications log their entries with the systems current setting, so I suspect it's in dovecot. I would very much appreciate any help on the subject. Btw, I'm using MacOS X 10.2 with dovecot 0.99.10.4. Thanks! /Lars

[Dovecot] Index abuse
by Rick Jones 28 Apr '04

28 Apr '04

How resilient is Dovecot's indexing mechanism? (seeing as it's been extensively re-vamped I guess this question may have different answers for 0.99 & 1.0). To put it in context, I'm playing with server-side automatic maintenance scripts for things like deleting messages more than x days old from folders a, b, c, etc. (using Maildir layout). So far I'm just zapping files in the cur and new directories and nothing amiss appears to happen from the IMAP client's viewpoint. I just wonder if I'm storing up trouble. Will the index files continue to hold references to non-existent files and get bloated, or do they self-clean? -- Rick Jones

[Dovecot] Feature request: more log info/stats
by Christian Balzer 27 Apr '04

27 Apr '04

Hello, even though Timo seems to be hibernating (it's not _that_ cold in ole Suomi ;) I'd like to beg for a feature that would be very much appreciated over here. If something like this is already present and eluded my thorough archive and doc searches, feel free to smack me and then point me to the right direction. Feature request: More extensive session information and statistics in the logs. Currently all I can get from dovecot is login information, there's not even a log entry when a session was ended either by the client or a timeout. In addition a short summary would be be very helpful, qpoppers one liner stats come to mind like this: --- Apr 12 05:30:30 test in.qpopper[21266]: Stats: test 6 21868 2 108126 some.do.main IP.AD.DR.ES [pop_updt.c:296] --- Stating that user test downloaded/deleted 6 mails with 21868 bytes total and kept 2 in the inbox. This might be expanded on for IMAP operations like moves or such and raw data about transferred bytes in/out added (in my case I get that info from perdition), but the really important parts are: When did a user log into the server, when did that session end? How many new mails were read and how many mails deleted during that session? The rationale is that with this info at hand the (unfortunately) very common user whining along the lines of "the mail server ate my mails" or "I never saw this mail!" are much easier to refute.

[Dovecot] Setting "default_mail_env" Why is index->mailbox_path empty?

I am trying to set up dovecot under linux. (RH9 if it matters). I'm having trouble having it find the mail that is already delivered. What I would like is that mail is delivered by fetch mail to /var/spool/mail/mclay (that me) then have dovecot find it. I'm sure that I have not set the dovecot.conf file correctly. The documentation is unclear as to what "mbox" is and "INBOX" is. I have tried having default_mail_env unset and with the following: default_mail_env = mbox:/var/spool/mail/%u:INBOX=:/home/%u/Maildir What I get when I talk to it directly is: $ telnet localhost imap Trying 127.0.0.1...

[Dovecot] RE: Missed config option
by Alex S Moore 26 Apr '04

26 Apr '04

I am trying to sync a set of maildir folders from a dovecot server and a different imap server on a different host. Using a perl tool called imapsync. The tool says the following about the two servers capabilities: >From capability : IMAP4rev1 SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN LISTEXT LIST-SUBSCRIBED To capability : IMAP4rev1 UIDPLUS CHILDREN NAMESPACE THREAD=ORDEREDSUBJECT THREAD=REFERENCES SORT QUOTA IDLE ACL ACL2=UNION No NAMESPACE capability in imap server sws601.mcsun.local Give the separator character with the --sep1 option The From server sws601.mcsun.local is dovecot. What did I miss that causes the NAMESPACE capability to not be seen from dovecot? What is the separator character? Thanks, Alex --

[Dovecot] imap errors filtering folders with evolution
by Brent Hills 26 Apr '04

26 Apr '04

Hello, I posted earlier to the Ximian Evolution Users list. It was suggested I follow up in relation to dovecot. They also indicated the timestamp in the error message was coming from dovecot. When filtering a folder on a dovecot (0.99.10) imap server with Evolution version 1.46 I receive: Error while 'Filtering Folder' Imap command failed internal error [YYYY-MM-DD HH:MM:SS] The timestamp seems to be the current time. The filters used are primarily move to folder where the destination folder is another imap folder on the same server. The error can be reproduced reliably if I select a large number of email to filter. There are about 10 filters all moving to different folders based on criteria. If I select smaller number of email the error occurs but less predictably. Eventually, it will filter all the email so its not a particular one that it hangs up on. Is anyone familiar with this issue? Brent Hills.

[Dovecot] dovecot dies - mabye a clue?

Dovecot died twice today.

[Dovecot] file permissions help!

26 Apr '04

Hi all! Ran into a problem and hopefully i can get some help. OK here is my set up: - dovecot-0.99.10.4 + MySQL patch. - Redhat 9 The authentication part works just fine. It gives me the following entry in the log file: imap-login: "Apr 12 22:15:10 "Info: Login: USER(a)DOMAIN.com [127.0.0.1] But there is a problem with dovecot reading the mbox file (I think). In the error file I get this entry: imap(USER(a)DOMAIN.com): "Apr 12 22:15:10 "Fatal: Failed to create storage with data: /export/htdocs/DOMAIN.com/mail/USER dovecot: "Apr 12 22:15:11 "Error: child 18613 (imap) returned error 89 Of course the user and domain info was changed. I am out of ideas but thats not to say its something easy or something I completely looked over.

[Dovecot] Problem with flags
by Jeff Hoskinson 26 Apr '04

26 Apr '04

Greetings! I'm having a problem with flags not working correctly. I'm using Mozilla Thunderbird as my mail client, and Dovecot 0.99.10.4 as part of Debian on a Sparc box. The thing that doesn't seem to be working right is Thunderbird's Label feature, which uses custom IMAP flags. I noticed that once I labeled a message, I couldn't un-label it. I recorded this exchange between Thunderbird and Dovecot while using the Label/None command on a message: 5235 uid store 35 -Flags ($Label1 $Label2 $Label3 $Label4 $Label5) * 35 FETCH (FLAGS (\Answered \Seen NonJunk $Label4 $Label5) UID 35) 5235 OK Store completed. Even though Thunderbird is sending the -Flags command for all its custom flags, the message is still retaining two of those flags. Just out of curiousity, I tried changing the flag of that same message to something different, and recorded this exchange: 5259 uid store 35 +Flags ($Label2) * 35 FETCH (FLAGS (\Answered \Seen NonJunk $Label4 $Label2 $Label5) UID 35) 5259 OK Store completed. 5260 uid store 35 -Flags ($Label1 $Label3 $Label4 $Label5) * 35 FETCH (FLAGS (\Answered \Seen NonJunk $Label4 $Label2 $Label5) UID 35) 5260 OK Store completed. So it seems the +Flags command works, but not the -Flags? Or does it have something to do with sending more than one flag at a time? Any help would be appreciated. Thanks, -- Jeff

[Dovecot] [OT] Is there a secure reverse IMAP proxy
by Sven Kirmess 25 Apr '04

25 Apr '04

This question is off topic. I ask this list because the question is related to security and IMAP and I guess the people in this list know a lot about both of that. Is there a secure reverse proxy for the IMAP protocol? Something you can install on a bastion host which checks the IMAP traffic before forwarding it to the internal IMAP server? There are these proxies for WebMail to IMAP connections but as far as I can tell they were not created for security reasons and not with security as primary goal. Sven

[Dovecot] problems with squirrelmail and TLS (debian unstable)
by Amelia A Lewis 25 Apr '04

25 Apr '04

Heylas, So, okay, I've had this lovely IMAP server running, and adore the ease of configuration, among other things. Problem, though. I'm trying to set up SquirrelMail, so that some folks with accounts on my box can use it without having to set up a proper imap client (or can check mail when they're at a cafe, or like that). However, I *won't* turn off the disable_plaintext_auth, 'cause I'm damned if I'll set up a box that asks people to send passwords in the clear, and there *are* people using imap. Dovecot cannot, currently, be configured to permit plaintext on localhost while requiring Something Better from the rest of the world. This becomes a problem with SquirrelMail, which can't cope with TLS. It just barfs. Looking at bug reports in debian, this has already been noticed, and the maintainer there (and the maintainers of SquirrelMail) considers this a non-problem, 'cause, they say, you shouldn't be using TLS with webmail. Is there a way to set up, for instance, two instances of dovecot, running on different ports, so that one listens to the external interface and the other listens to localhost? I don't much like the idea, but how would I go about doing this? Two copies of dovecot.conf and a command-line switch? Amy! -- Amelia A.

Hi, Your mail was very insightful. You have stated in you mail as follows .. "But I think they create virtual users in database systems for email, I can't imagine all of the users they have are in one passwd file on one tiny machine." a. What do you mean by virtual users. b. How does one link them to a mailbox. Very frankly i am confused... 1.Well lets say i have a user who wants to create a new group say GROUP1.Lets say i have users who want to create GROUP1(a)pigeonhole.com or GROUP2(a)pigeonhole.com .This group name will be entered in my JSP page, now what do i have to do to create the group. 2.How do i see to that anyone who sends a mail to GROUP2@pigeonhole receives it in it mailbox( Firstly does the group have a mails box in the groups name).Will one create a account(mailbox) for the group or how is it done. 3.Lastly I actually want to create a mailing List manager.

Re: Re: [Dovecot] adding new user to dovecot
by Kartik Vaidyanathan 18 Apr '04

Hi, Thanks a lot for the mails.Well one major doubt that was prevailing was that do i need to create a system account for each person in order to send/receive mails, and from both(Sven Kirmess & Johannes Berg ) your mails i gather it is a must. But Is there a workaround to this? I have actually configured dovecot because i required a mail server in order to build a mailing list manager.A mail list manager is something in the likes of yahoogroups, where each group in my case must have a mailbox. 1. I am using Debian OS. The software that i am creating , which is going developed in JSP, will take a new users name and password and create a account for him by executing a shell script in my linux machine.I assume yahoo also does something similar to this to create new mail boxes for any new user.Please correct me if i am wrong. In fact this very mail that i have received from you is because i have subscribed to the dovecott mailing list. How do you think dovecott has been able to accomplish this. Is it not because that dovecott has a mailbox in the group name "dovecott" in some system, that internally does the sending of mails to all those in the groups refering to some database. 2.Will the mail server support me in anyway by giving me some functionality to add users, thereby creating maildir's (imap) for the users. 3.Dont I need to know the admin login and passwd, to create users? 3.Lastly i know this is not that prevalent a question -> I was told mail man does a similar job as to what my software will do.Do you know how mailman works (or even yahoogroups)?. Please enlighten me on the above issues. Thanks a lot for you time. Regards Kartik

[Dovecot] adding new user to dovecot
by Kartik Vaidyanathan 15 Apr '04

15 Apr '04

Hi, This is from your documentation Creating new users ------------------ Dovecot is interested in only one thing - being able to find the user's mail directory. With maildir you need to do mkdir ~user/Maildir, with mbox mkdir ~user/mail. what does ~ refer to. Pardon my ignorance in unix, i am relatively new to unix. Does not ~ refer to the user account in which you have logged in. So does that mean that maildir folder exist for only user accounts that already exist.My intention for asking the above is that i have a java program running, that will take a new users name and password, so with that can i create a mailbox for that person , or does the admin have to create an user account for that person , so that his maildir folder can be created. Please clarify my understanding of how it workds.. Thanks

[Dovecot] Dovecot for production environment

Sorry if this question has been asked before I looked through some of the archives before posting this. I am considering using dovecot on a small 35 user environment (only around 6 gigs of email) that will be primarly be used with squirrelmail for the MUA. I have been using dovecot for a few weeks now and really like it. It is a big improvement over uw-imap thats for sure. I was wondering how many people in this mailing list are using dovecot for a production email server, and why you chose to use dovecot over cyrus or courier. Or maybe someone feels that dovecot isnt ready for this type of thing just yet. I am all ears so please feel free. Thanks -- Avery -- Avery Day

[Dovecot] Missing mail file - Internal Error

I have noticed that if the user does not already have a mail file, for instance in /var/mail, the IMAP server responds with Internal Error, and the pop server imediately terminates the connection.

[Dovecot] blank line at the top of mbox
by KB Digital 10 Apr '04

10 Apr '04

Hello, It seems dovecop pop3 server sometimes inserts a blank line at the top of the mbox. It only happens for certain users not all. I'm not sure why it's doing that. Looking back into the mailing list, I saw the same post in Oct 6, 2003 but there was no reply to it. Is there a patch or fix that i can use to get around the blank line? Thank you. Ken

[Dovecot] (no subject)
by Avery Day 09 Apr '04

09 Apr '04

Sorry if this question has been asked before I looked through some of the archives before posting this. I am considering using dovecot on a small 35 user enviorment (only around 6 gigs of email) that will be primarly be used with squirrelmail for the MUA. I have been using dovecot for a few weeks now and really like it. It is a big improvement over uw-imap thats for sure. I was wondering how many people in this mailing list are using dovecot for a production email server, and why you chose to use dovecot over cyrus or courier. Or maybe someone feels that dovecot isnt ready for this type of thing just yet. I am all ears so please feel free. Thanks -- Avery

[Dovecot] Dovecot startup at boottime fails
by Bavo De Ridder 08 Apr '04

08 Apr '04

Hi, I am running dovecot 0.99.10.4 on SuSE 9. I installed it using apt-get from the gwdg repository. The dovecot service is configured to start at boottime in run level 3 and 5. However, it dies immediately with this error (/var/log/mail.err): dovecot: Login process died too early - shutting down Starting the service afterwords from a prompt as root with the command: /etc/init.d/dovecot start works without a glitch. Attached you can find my dovecot.conf and the startup script /etc/init.d/dovecot. I hope someone could shed some light on this issue.

[Dovecot] dovecot vs. cyrus IMAP?
by Jim Norton 08 Apr '04

08 Apr '04

Hello all, I just learned about dovecot. I am currently using Cyrus IMAP/POP3 with Postfix on a Linux system. The one thing I don't like about Cyrus IMAP is that it doesn't support mail users who have accounts on the system. It uses it's own mailbox format and the users can't be regular system users. It would be nice to have an IMAP/POP3 server that can handle mail for users in /etc/passwd as well as the cyrus 'virtual' user type. Does dovecot only provide access to mail for users in /etc/passwd? Or can one setup email accounts for people that don't have accounts on the system ( in /etc/passwd )? Thanks, -- Jim Norton - http://www.jimnorton.org Recursion; n. see 'Recursion'

[Dovecot] username and password not from /etc/passwd
by Zoong Pham 08 Apr '04

08 Apr '04

Can dovecot use usernames and passwords not from /etc/passwd and be able to read mails of an user whose username and password are in /etc/passwd ? For example: - Joe Bloke has a local Unix account joe on Unix server mail.example.com - Sendmail on mail.example.com accepts mails for joe(a)example.com and put them in /var/mail/joe - can dovecot use other username/password file or database or directory rather than /etc/passwd to authenticate Joe and let him (once logs in successfully) reading mails in /var/mail/joe ? Ideally, the usernames and passwords that dovecot uses are different with the ones in /etc/passwd. Say, username is joe.bloke(a)example.com That way, Joe doesn't need to know the username and password on the Unix server at all. In summary, I want to have IMAP usernames and passwords totally different from the local Unix usernames and passwords. And users use only IMAP usernames and passwords to read their mails. I use OpenBSD-3.4, Sendmail 8.12.9, dovecot-0.99.10p0 (pre-compiled packaged from OpenBSD). Thanks, Zoong Pham

The correct behavior should be to only download the new message. from doing a search on dovecot and uidl, it seems that dovecot supports these functions, which is the standard way for a pop3 server to announce unique checksums of messages.

[Dovecot] Repeating downloads
by Paul Hanson 07 Apr '04

07 Apr '04

Hey- Just wanna say that I'm really happy with Dovecot, it has worked really well for my small operation. I do have a couple problems I'd just like to bring to everyone's attention for future bugfixes and if there is a solution available. I'm using dovecot-0.99.10-6 with a clean fedora core 1 install. I'm using primarily IMAP with OpenSSL, however a few people use POP3 (over SSL) with outlook 2002 clients. The problem is that with each send and receive another copy of all messages in their Inboxes are downloaded. I have tried closing outlook restarting it etc. nothing seems to help unless I tell outlook to remove all messages from the server then outlook responds with "messages that outlook was attempting to download are no longer on the server." And problem solved. Not a huge deal but others with similar setups may be experiencing the same problems. I have postfix for my MTA, every account uses Maildir. Attached is my dovecot.conf. Thanks a lot!!! -Paul

[Dovecot] dovecot with sendmail
by electron electron 06 Apr '04

06 Apr '04

Hello, Here is an issue. I am trying to make dovecot work with sendmail If I use the default conf file (default_mail_env = ) then the inbox is the file /var/mail/user and a mail folder is created in /home/user directory where it stores all additional imap folders. The problem with this is that I cant have subfolders. If I edit dovecot.conf file and enter default_mail_env = maildir:/var/mail/%1u/%u/Maildir then I can create subfolders, but new emails are not stored in INBOX, but the stay in /var/mail/user. In order to overcome this issue I used procmail .procmailrc: ---------- { :0 Maildir/ } ---------- So now all emails are stored in Maildir format and again with the default dovecot.conf file it works fine. I was wondering if there is an alternative way to do this, without using procmail..just editing the dovecot.conf file.

[Dovecot] dovecot not reconnecting to ldap after ldap restart
by Jared 05 Apr '04

05 Apr '04

I upgraded dovecot two weeks ago from 0.99.10-0.rc2 to 0.99.10.4-1woody1 (both from the woody backport packages from braincells.com) Dovecot is using LDAP on a separate machine for authentication. (through stunnel if it matters) At 4:00 am, the LDAP server stops, dumps the ldap database, and then starts back up. Because the LDAP server is stopped, anyone who tries to authenticate during the few seconds will be denied. This isn't a big deal since it's 4:00 am. However, twice in the past two weeks, it appears that if dovecot can't connect to the LDAP server, it loses the ability until dovecot is restarted. It's only happened since I upgraded, and it's only happened twice, presumably when someone was trying to check their mail at the precise moment the LDAP server is down. I get the following entry in mail.err: Mar 30 04:00:18 akbar dovecot-auth: LDAP: ldap_result() failed: Can't contact LDAP server Mar 30 04:00:19 akbar dovecot-auth: LDAP: Can't connect to server: localhost Mar 30 04:00:50 akbar last message repeated 36 times . . . The two times it has happened, ldap is responding properly (all other services we provide which use LDAP still work), stunnel on the dovecot machine is still running, and dovecot is still running, accepting IMAP and POP connections, but failing at the authentication phase. Is there some change or bug in dovecot which would make this happen? Or is there a problem with my set up? Thanks in advance for any ideas. -jared

[Dovecot] passwd-file maintenance by users, other options
by Mike Brown 04 Apr '04

04 Apr '04

I am using Dovecot to provide IMAP and IMAP+SSL service for my users, but am still using QPopper for POP3 service, wrapped with stunnel for POP3+SSL. I am hesitant to get rid of QPopper because it supports APOP, which encrypts authentication data (both where it is stored, and when it is transmitted), and because APOP passwords can be managed by the users themselves, via the popauth tool that they can run from their shell accounts. I'd like very much to use Dovecot for POP3, but would need to have it be comparable to APOP, where authentication does not involve having user passwords going across the wire in the clear, and especially I need for users to be able to maintain their passwords themselves, preferably with their status as a current user of the system being established without my intervention; I don't want to have to manually keep things in sync with /etc/passwd. Furthermore, it needs to have no conflicts with popular email clients including Mozilla, Outlook, Outlook Express, and Eudora, so unusual authentication mechanisms are not really an option. I've RTFM at http://www.dovecot.org/doc/auth.txt but I don't know how to establish a separate passwd file that would satisfy the requirement that users be able to maintain their passwords themselves. And PAM is a complete mystery to me. So what do you all do? Is there a tutorial somewhere that would help? Thanks, M.

[Dovecot] Bug fix - message/rfc822 attachments
by Rick Jones 03 Apr '04

03 Apr '04

Greetings I've attached a patch that fixes a bug in Dovecot relating to rfc822 attachments. This problem shows up in Mulberry (which hammers the IMAP protocol more than most!). The problem is that FETCH BODY[n], where "n" is the number for the message/rfc822 part, returns the wrong information. It returns the message without the headers, whereas it should return the entire rfc822 attachment. FETCH BODY[n.MIME] doesn't appear to return the MIME headers for the part either. This happens because the find_part() function always steps down into the child when the type of the part is RFC822. It should only do this if the request is for a sub-part, or for HEADER. Otherwise it should stay at the current level. I have to say the IMAP protocol is a bit perverse in the way implicit nesting of rfc822 messages is handled, which is why this looks somewhat hacky. I don't see a nicer way though. The effect in Mulberry is that certain operations on rfc822 attachments don't work properly, in particular extracting the attachment into a separate message. It also affects message-digest format messages, which will completely lock up Mulberry if one is even present in a mailbox. (It may be that Dovecot itself hangs, I don't know. Once I found that the patch fixed both problems I didn't look any further :) Mulberry doesn't exhibit these problems with other IMAP servers. The attached patch is for the source code of 0.99.10.04. I've looked at the "latest" source, and there is no change in these lines of code, so I guess the bug is still there. -- Best regards Rick Jones

[Dovecot] Failed to create storage with data
by Tim Middleton 01 Apr '04

01 Apr '04

Switched from UW-IMAP to dovecot a little while ago. Worked through the namespace hell with current users. But now I've hit another problem I can't seem to figure out. Some webmail (squirrelmail) users noticed that when they tried to login they would jus get this error: ERROR: ERROR : Connection dropped by imap-server. Query: CAPABILITY I discovered in the mail logs the real error was like this: Apr 1 04:28:38 smaug imap(mcfletch): Invalid mbox file /var/mail/mcfletch: No such file or directory Apr 1 04:28:38 smaug imap(mcfletch): Failed to create storage with data: mbox:/var/mail/mcfletch And the error seems to be quite accurate. These are new logins seeing this error, which do not yet have an mbox file. So the question is, why is dovecot not able to deal with this situation? Searching google i saw the suggestoin to one preson that it was actually the ~/mail directory unable to be created, but this is not the case in my test above, as ~/mail already existed for that account. Directory permissions seem okay. /usr/mail is drwxrwxrwt (note: /var/mail is a symlink to /usr/mail on this system). The dovecot setup is fairly default. Platform is FreeBSD 4.9. Authentication is done via system password file. There's no problem accessing/modifying existing mailboxes. I put in a chron job to touch into existance any non-existing mailboxes for everyone in the passwd file periodically, which mostly eliminates the problem. But I'd still like to know why the server is having the problem, if anyone can make any suggestions. -- Tim Middleton | Cain Gang Ltd | "Are the gods not just?"

[Dovecot] Mulberry problem
by Rick Jones 01 Apr '04

01 Apr '04

I've been chasing a problem with Mulberry which now actually seems to be a Dovecot server bug. The problem manifests itself when manipulating embedded rfc822 messages, and the analysis comes down to the fact that a FETCH BODY[2] command returns the same thing as FETCH BODY[2.1]. Both return just the text of the embedded message, whereas FETCH BODY[2] should return everything including the headers (this is what Cyrus Daboo came up with after looking at the Mulberry log). I'm not sure exactly what version of Dovecot I'm running, it's what comes with SME Server 6.0. Has this by any chance been fixed? I have another Mulberry problem which might be related, but I'll save that for another post :) -- Regards Rick Jones

[Dovecot] Rogue child imap processes when using Mac imap clients
by darren david 31 Mar '04

31 Mar '04

hi all- I am currently running dovecot 0.99.10p2 on OpenBSD-3.4-snapshot. It has been very stable, but I have recently noticed that I am having problems when checking IMAP-SSL mail with Mac OS X clients. There are not problems using Mozilla or Outlook on Windows, but Mac clients (Thunderbird, Mozilla, Mail.app) all exhibit the same behavior - they can check and send mail, but I end up with a single, rogue child imap process on the server that pins the cpu that i have to 'kill -9' to clear out. Is this a Mac problem or a Dovecot problem? I'm not even sure what to look for in the logs... Thanks, Darren David

[Dovecot] New indexing code
by Timo Sirainen 31 Mar '04

31 Mar '04

Sorry about the lack of replies to questions in this list. Work on the new indexing code has taken way too long, but it's finally beginning to be get near usable state. After it's fully working, I'll start being more active here again. If you're interested (as a developer, normal users shouldn't even try playing with it yet), you can checkout "newdove" module from Dovecot CVS. Many things are still broken, but basic maildir support is almost working with the exception of expunges (which probably break badly) and custom flags (not implemented). And the maildir syncing code isn't optimized yet. Don't try it with any of your real maildirs, it might lose your mails. Some of the new great things in it: - Mailbox API which is a lot more easier to use than before, allowing a lot of things that previously were difficult to implement - Less IMAP-specific than before - Should work extremely well with shared mailboxes with tons of users I'm hoping to get a usable alpha release out of it within few weeks.

Now, I have a file in the maildir folder named dovecot-uidlist.lock that must be corrupt. How do I fix this? I can remove this particular maildir folder and there is no great loss. But I want to know how to fix it, in case this problem occurs on an important folder. Thanks, Alex

[Dovecot] RE: Locking problem
by Alex S Moore 20 Mar '04

20 Mar '04

Running dovecot on Solaris 8 sparc with SylpheedClaws as the MUA. I tried moving to many messages from a folder to my maildir folder, which is a local directory on the dovecot server. Now, I cannot open the folder due to this message: 'Mar 20 10:26:15 sws601.mcsun.local imap(amoore): [ID 702911 mail.error] Timeout while waiting for release of shared fcntl() lock for index file /var/indexes//amoore/.Spam.Spam Archive/.imap.index' How do I get the lock released? I changed some timeout settings in dovecot.conf, but that did not help. Every time that I click this particular folder in my MUA, the screen locks up. Thanks, Alex

[Dovecot] Case insensitive user names
by andrew fresh 19 Mar '04

19 Mar '04

I am trying to set up the Dovecot pop3 server for some virtual hosting I am doing and it is going well, I am generating a passwd file that points dovecot to the virtual users mailspool. The only thing that I don't have working is that my current pop3 server (NTMail) has case insensitve usernames. Dovecot doesn't. I was hoping there was just an option to turn on, but I didn't see one, and unfortunately I don't know enough C to change to lc($submitted_user) eq lc($database_user) like I would in perl :-) I do have control over generating the passwd file, and it is currently generating the users to lowecase in the file, so just lc($submitted_user) eq $database_user would work well enough. Unfortunately I don't know enough C to do that, so I thought I would ask if anyone has done this. So, does anyone have any ideas on how to do this?

[Dovecot] chdir() on NFS
by Christian Andersen 19 Mar '04

19 Mar '04

Hi, I'm having problems accessing home directories though NFS. This setup uses LDAP and Kerberos. Users defined on the local host work fine. This is what dovecot writes in the logs while trying to log in as the user johndoe: ---- Mar 19 14:10:54 jack dovecot-auth: nss_ldap: reconnecting to LDAP server... Mar 19 14:10:54 jack dovecot-auth: nss_ldap: reconnected to LDAP server after 1 attempt(s) Mar 19 14:10:54 jack imap-login: Login: johndoe [10.0.0.30] Mar 19 14:10:54 jack dovecot: chdir(/home/johndoe) failed: Permission denied Mar 19 14:10:54 jack dovecot: child 3525 (imap) returned error 89 ---- The authentication is OK, but dovecot fails to get access to the home directory. What username does dovecot try to chdir() as? If I 'su' from to that user I have access to /home/johndoe, and a quick test with Courier IMAP worked fine. Postfix has no problem delivering mail in the users maildir using procmail. Some relevant config options: default_mail_env = maildir:~/mail:INDEX=/var/indexes/%n auth_userdb = passwd auth_passdb = pam auth_user = root -- Christian Andersen <http://phuzz.org>

RE: [Dovecot] Dovecot failing silently on startup

> Can you do an strace of a running dovecot process so we can > get a better idea? (You ought to cc the list as well.) Sorry for the slow reply, it's taken me a few days to get back to this and observe the problem again. I've placed a tarball of the output of "strace -ff -o dovecot dovecot" here: http://rimu.tiddly-pom.com/dovecot-strace.tar.gz To my (admittedly untrained) eye, it's looking for and not finding /etc/ld.so.nohwcap, and then repeatedly not finding /var/run/dovecot/ssl-parameters.dat. At that point there is a /var/run/dovecot/ssl-parameters.dat.tmp - is that where the SSL stuff is being generated? Is it just that Dovecot is stalled until the ssl-parameters.dat file appears? Thanks, Julian.

[Dovecot] duplicate mails
by Neal D. Becker 18 Mar '04

18 Mar '04

I run kmail and use it to automatically sort my mails to various imap folders (using kmail's disconnected imap). If I fire up a second instance of kmail (e.g., @work + @home) then both will do this, and I wind up with 2 copies of each mail. Can dovecot be taught to discard duplicate mail ids, or maybe some other mechanism to avoid this problem?

[Dovecot] triggering multiple actions on pop-3 request
by Eric S. Johansson 17 Mar '04

17 Mar '04

I want to trigger fetchmail when a user makes a pop-3 request. The reason for this is so that the messages retrieved by fetchmail can be filtered via an anti spam service before depositing them into the inbox. The way I figure it, since I need to know who the user is and that they authenticated in order to make the correct fetchmail call, I need to spawn the fetchmail process somewhere between the authentication and the pop 3 process. since I'm currently unfamiliar with code at that level, could I get a suggestion as to where to start looking?. apologies if I haven't explained is clearly enough. I'm still just kind of exploring the idea myself to see if it's the right way to approach this problem (pop 3 anti spam Gateway). If it works out right, it may even end up as part of a firewall (IPCop) as a way of making anti spam trivially easy for the technically challenged. (I.e. put it in a box, said it up right, don't let them touch it) I know it is also somewhat off topic for the group but since I want to modify dovecot (the IMAP server that rescued me from UW), I figured I would give it a shot. thanks in advance, ---eric

[Dovecot] Corrupted Indexes and File Permissions
by Dominic Marks 16 Mar '04

16 Mar '04

Hello, I'm using Dovecot to provide an IMAP service to a small number of users and I'm seeing two recurring errors which look like they might be related. Environment: o FreeBSD 5.2.1 / Postfix 2.0.18 / Dovecot 0.99.10.4 o Maildir mailboxes Problem: On logging in all the folders under the users mailbox are empty. This has happened with both MS Outlook 2000 clients as well as Squirrelmail which uses c-client. When you look at the mail log it shows errors from Dovecot about index file corruption and file permissions (see attached sample section). I've checked the permissions on the maildir and it seems at the moment that the user has rw permssion on every file under cur, could this error be caused by an interaction between Postfix and Dovecot? Any comments / suggestions greatly appreciated, -- Dominic Marks

[Dovecot] index file corruption
by mat＠reynerie.org 16 Mar '04

16 Mar '04

Hi, I'm using Dovecot (dovecot-0.99.10p0) on OpenBSD-3.4 for few weeks now. When i connect to my IMAP account the connection is often closed by dovecot when i try to delete mails. I can see messages like this in log: Feb 29 18:47:00 po imap(mat(a)reynerie.org): Corrupted binary tree file /home/mat/Maildir//.INBOX/.imap.index.tree: used_file_size larger than real file size (1772 vs 1556) I tried to remove all index files, but the problem still occur. I also tried Maildir and Mbox, same problem (i can't remember if the log are similar with mbox, if needed i will test again). I have ktraced the imap process and try (succesfully) to reproduce this behaviour: I have re-send a lot of spam and delete few of them from mailbox until the problem occur. All logs/kdump/config are here: http://mat.reynerie.org/dovecot/ In the kdump file, the problem is visible at the end, Dovecot is compiled (via ports) with: env CFLAGS="-I/usr/local/include -L/usr/local/lib" CONFIGURE_ARGS="--with-ldap --with-ldap-includes=/usr/local/include --with-ldap-lib=/usr/local/lib" make Searching the mailing list archives, i have not found any solutions. -- mat

Re: [Dovecot] Mysql patch question
by Skye Poier 16 Mar '04

16 Mar '04

Last question of the day I promise :) If dovecot is configured to use the MySQL patch, ie: auth_userdb = mysql /path/to/dovecot-mysql.conf auth_passdb = mysql /path/to/dovecot-mysql.conf Its not possible to "chain" authentication methods is it? I mean, if its using MySQL it _cannot_ be configured to check passwd (via "pam *") first, and then check mysql, right? So, if I want to support real shell users (who are in /etc/passwd) I will have to have them in mysql along with the "virtual" users. ...... OK I lied, one more question! I love the feature that you can login with a username user@domain and the domain is automatically parsed out. Do these options have anything to do with the @domain part (referred to as a realm in auth.txt) or are they for something else completely? I'm not sure what SASL is that it refers to in the example .conf #auth_realms = #auth_default_realm = Thanks, Skye

[Dovecot] Help with dovecot+passwd+pam_mysql
by Skye Poier 15 Mar '04

15 Mar '04

Hi again, I'm on Freebsd 4.x and instead of using the mysql patch, it seems like it would be easier to just use "auth_passdb = pam *" with the pam_mysql drop-in. I'm not really a pam.conf writing expert though. Here's what it currently contains (works for /etc/passwd users) imap auth required pam_unix.so imap account required pam_unix.so try_first_pass imap session required pam_deny.so How would I set it up so that it first checks to see if the user is in /etc/passwd (as above) and then checks pam_mysql.so? Example from the pam_mysql readme: auth optional pam_mysql.so user=root passwd=password account required pam_mysql.so user=root passwd=password Is anyone else using this setup? Any disadvantages? Thanks, Skye

Hello, sorry if this gets asked a lot :) When is the next version of dovecot planned for release? Will it include non-patched MySQL support? Can I make a donation to speed up the process? I have used about 5 different IMAP servers in the last month trying to find one that didn't suck.. and I'm happy to say dovecot is the best!! Thanks, Skye

[Dovecot] dovecot & vpopmail
by Dirk Jäckel 12 Mar '04

12 Mar '04

Hi! Authentication works, but default_mail_env = maildir:/usr/local/vpopmail/domains/%d/%n/Maildir/ is translated by the "imap"-process to /usr/local/vpopmail/domains//testerhorst/Maildir/ although I succesfully log in as testerhorst(a)elektropost.org. Is there a manual how to use dovecot with vpopmail? We have here: FreeBSD 4.9-STABLE, vpopmail-5.4.0 and dovecot-0.99.10.4_2. Thank you for your help! Regards, Dirk Jaeckel

Well I've tried a number of different permissions , uid , gid What I have are mail server permissions on the spool folders where the users are virtual. The mail server runs under exim:mail and I have tried unique uid:gid and exim:mail uid:gid To access the directories as well as the folder permissions 770 750 etc. Dovecot is running as it's own user (imapd) What should they be working as ?

[Dovecot] imap internaldate
by Payton 10 Mar '04

10 Mar '04

I think I found a bug in dovecot which I'm not sure where to fix. (I may even have found a reference to it in an archived list message from Jul 2003.) Here is the situation: dovecot (dovecot-0.99.10.4) running with an imap server on an mbox system is queried by a local client program, like Mail.app, and is told the "Received" date of the message (presumably sent through INTERNALDATE), however, that date is being passed on in GMT (-0000) instead of the server or client's local time zone (EST -0500, in this case). Maybe it's assumed that the local client will convert this time to the local zone, but no clients I know actually do that. Anyone know how/where to fix this? Thanks! - Payton - payton(a)repligen.com
