[Dovecot] dspam plugin
by Tom Bombadil 02 Feb '07

02 Feb '07

Hi all... I was looking into the dspam plugin, and it looks very interesting. I saw two version of it around: - one that forks and call dspam - one that calls a store procedure in mysql. I was wondering if we can just log signature and classification into a flat file, instead. The problem is that calling spam can be expensive; And eventhough the myslq solution is brilliant, I dont want to rely on mysql to be alive in order to move the files to/from spam box. Plus, the plugin would be much lighter wihtout libmysqlclient. Any ideas?

As I've decided not to manage my own mail server, I'm trying to unsubscribe from the dovecot list. However, the page at http://www.dovecot.org/mailinglists.html is down. Does anybody have the welcome email, so that they could tell me to what address to send the unsubscribe command to? Thanks in advance.

[Dovecot] Query: LSUB "" "*" still on rc19
by Gavin Henry 02 Feb '07

02 Feb '07

Hi all, We've downgraded to rc17 for the past week or so, as when we upgraded to rc19, this error did go, but came back again. ERROR: Could not complete request. Query: LSUB "" "*" Reason Given: Internal error occurred. Refer to server log for more information. Looks like it never helped us in rc19. Back on rc17 just now, which we still have to restart a few times a day, do to the LDAP stuff (which was fixed in rc18/19), but at least we can get in ;-) Which logs settings/debug do you need to get more info?

[Dovecot] mailbox corruption by pop3 access
by dovecot＠quartzcrystal.org 02 Feb '07

02 Feb '07

I have about 30 pop3 users at my dovecot server, and sometime there's mailboxes (/var/spool/mail/userid) are corrupt. Troubled mailbox contains unnecessary 2 lines on head of file. Example is follow... ------------------------ .93C7E660-- >From xxxxxx(a)xxxxx.com Tue Jan 16 19:29:21:2007 ------------------------ 3rd and following lines has no plobrem. Maybe, this first line is last line of previous mail. But I don't know why it was leaved. At such cases, when user tried to get his mail by pop3 client on remote host, and close connection by server immidiate. ------------------------ -ERR Mailbox isn't a valid mbox file Connection closed by foreign host. ------------------------ Every time I delete 2 lines from his mailbox to restore on server console when it corrupt. Has anyone such problem? OS: RedHat Enterprise Linux 4 Dovecot version: 0.99.11-4.EL4 (RH official rpm)

[Dovecot] Multiple Trash patch for DSPAM plugin
by Hugo Monteiro 01 Feb '07

01 Feb '07

Hello all, First of all my respects to Johannes for the nice dspam plugin he created. Unfortunatly i got stuck with a problem in that same plugin since it didn't allow the use of more than one Trash folder. That can be an issue if you have a wide variety of clients working in a wide variety of languages. Not all use the english "Trash" for that folder. I've written a small patch to accomodate that situation and it's working just fine for me. I'm submitting it in the hope that it can be usefull to others. Hope it's usefull for others too.

[Dovecot] Performance, dovecot vs tpop3d
by Nate 01 Feb '07

01 Feb '07

Hello, I am new to the list and have spent extensive time researching performance suggestions through the list and the documentation. Particularly interesting is the recent performance thread related to the upcoming release. I just upgraded one of our email servers from tpop3d to dovecot 1.0rc19. tpop3d has served us well for many years; however, it basically has lost all it's support and developers. My main liking of tpop3d was it's speed. After the upgrade to dovecot, the server began to crawl. This server runs postfix for the delivery agent and now dovecot for pop3 and imap. The box serves roughly 9000 virtual maildir mailboxes with roughly 20 pop3 processes active at any given time. I ran some tests this morning to determine an exact difference between running tpop3d and dovecot. dovecot: I/O load averages 81%, System load averages 12.00 tpop3d: I/O load averages 20%, System load averages 0.50 To ensure it wasn't just a fluke of logins, I let each app run for several minutes, and did the test multiple times. The results were not any abnormal user usage and definitely related to application performance. My current settings in dovecot related to performance are: mmap_diable = yes mmap_no_write = yes Modifying these to no seems to decrease performance slightly but only a few percent. I have also played with various other settings, which didn't give me any significant performance boost. I'm eager for the next release which will have the fsync_disable option to see if that helps, it certainly looks promising. One observation where the majority of the load seems to be generated from is when a pop3 connection is loading up a very large maildir. The pop3 process seems to remain around using I/O for a considerable time, even when the user has no new email. Perhaps it is rebuilding or verifying it's index files? Here is an example of a lsof of the pop3 process with a user who has roughly 17000 messages. They check their email every 10 minutes which seems to add significant load. Note the final line, it's reading an individual message file, yet the user has no new email since the last login. If i keep lsofing the process, the final file seems to change and keep going through many of their mailbox files. The process takes many minutes to complete. Is it rebuilding the index on every login?

Thank you for any help offered! I'm hopeful for any suggestions to solve this performance issue or diagnose it further to determine the cause. - Nate

[Dovecot] Making POP3 not retrieve deleted messages
by Aredridel 01 Feb '07

01 Feb '07

Since my users often use the webmail system to delete messages to save their poor strained dial-up POP3-using mail clients, and our new web mail system isn't expunge-happy like the last one, I found need for this patch -- it adds a configuration option for pop3 "pop3_ignore_deleted", a boolean, that does just that. I'd love feedback. Aria

[Dovecot] Mail Answered status flag in pine stopped working in rc19
by Carl Mason --- Director Demography Lab 01 Feb '07

01 Feb '07

The Flag indicating that a message has been Answered does not work in pine. The status flags for New and Deleted work as always. The Answered flag worked properly in dovecot 0.99, but after upgrading to 1.0rc19 it stopped working. Interestingly, mail that was answered before upgrading to rc19 still shows the proper flag. I have tried with mbox_dirty_syncs turned on and off and I have tried putting "flags" in mail_cache_fields. Obviously I am wandering in the dark. Here is the setup: pine 4.64 dovecot 1.0rc19 (installed from rpm dovecot-1.0-2_40.rc19.el4.at.i386.rpm) Centos 4.4.2 x86 mail_location = mbox:~/mail/:INBOX=%h/.mailspool/%u:INDEX=/var/dovecot_indexes\/%d/%n Inbox is NFS mounted, INDEX is on local disk Thanks.

That test was on my list to try out today. I ran the test, and performance was severely degraded. Upon every new login, the entire index was rebuilt. So with any login it takes the full ~30 seconds to rebuild the index on a 17000 email user. I've confirmed also that tpop3d is doing no indexing whatsoever on disk. It isn't even compiled with that option. So it seems it is probably disk caching which is assisting tpop3d with returning a 2nd login (within a few minutes) so quickly. I wish it were the case that all users downloaded messages, but it seems all too often users click the 'leave messages on server', and never expire them. We have quite a few users (thousands probably) in that condition. We occasionally delete old stuff. Did I hear about an expire plugin upcoming? That would be useful. - Nate

[Dovecot] Sieve and LDA
by Vincent Bernat 31 Jan '07

31 Jan '07

Hello ! I have started to use Sieve support in LDA. From the RFC a same message should not be delivered twice in the same folder : ,---- | 2.10.3. Message Uniqueness in a Mailbox | | | Implementations SHOULD NOT deliver a message to the same folder more | than once, even if a script explicitly asks for a message to be | written to a mailbox twice. | | The test for equality of two messages is implementation-defined. | | If a script asks for a message to be written to a mailbox twice, it | MUST NOT be treated as an error. `---- Dovecot seems to ignore this "SHOULD NOT" or am I missing something ? At first, I thought they were speaking of case where there is two idententic "fileinto" directive in the ruleset. Something like : fileinto "box"; fileinto "box"; But, I don't think that they would they "the test for equality of two messages" with such a trivial case. Maybe dovecot should maintain a list of recent message-id seen for each user (with the associated mailbox). -- I WILL ONLY DO THIS ONCE A YEAR I WILL ONLY DO THIS ONCE A YEAR I WILL ONLY DO THIS ONCE A YEAR -+- Bart Simpson on chalkboard in episode 3F31

[Dovecot] Need help with "mbox sync" problem
by Jim Garrison 31 Jan '07

31 Jan '07

The following is occurring consistently on users in only one vhost domain. Other vhost domains are not having the problem. The email client in use is the same (in both the working and non-working domains). dovecot: Jan 29 21:19:18 Error: POP3(user1(a)mydomain.tld): mbox sync: UID inserted in the middle of mailbox /var/mail/vhosts/mydomain.tld/user1 (5629 > 5423, seq=2, idx_msgs=5) dovecot: Jan 29 21:19:18 Info: POP3(user1(a)mydomain.tld): Disconnected: Logged out top=0/0, retr=95/508506, del=95/95, size=506866 dovecot: Jan 29 21:19:52 Error: POP3(user2(a)mydomain.tld): mbox sync: UID inserted in the middle of mailbox /var/mail /vhosts/mydomain.tld/user2 (5634 > 5629, seq=2, idx_msgs=95) dovecot: Jan 29 21:19:52 Info: POP3(user2(a)mydomain.tld): Disconnected: Logged out top=0/0, retr=5/69654, del=5/5, si ze=69562 Once this message starts occurring, dovecot stops deleting retrieved messages when the user retrieves mail (with 'delete from server' set). The result is that the entire mailbox contents are fetched each time, resulting in copious amounts of duplicate messages. I'm on the rc8 RPM that comes with FC5, but am willing to remove it and install a later Dovecot built from source. 1) Is this a known problem that can be fixed by upgrading? 2) If not, can someone tell me what this message means exactly, and how to gather more information for debugging? The MTA is Postfix. Thanks

[Dovecot] How to prevent SQL injection
by Jochen Schulz 31 Jan '07

31 Jan '07

Hi, on my way home today I thought a little bit about my setup which involves user and password lookups in an SQL database (Postgres). I asked myself whether I need to do anything to prevent SQL injection via forged user or domainnames. In the wiki I didn't find anything specific, only http://wiki.dovecot.org/Variables which mentions that there is the %E modifier which escapes single quites and backslashes. This appears to be a good idea but I am asking myself whether I need to do this since it is not mentioned anywhere. Is anybody able to comment on this? And BTW, it appears that one can use several modifiers at once. This is only implicitly mentioned in the wiki (You can apply modifier*s*), but it appears to work.

[Dovecot] Looking for IMAP maintenance tools
by Jens Knoell 31 Jan '07

31 Jan '07

Hi I'm currently prowling for some IMAP tools to help me maintain our mailboxes. I'd prefer "pure" IMAP, i.e. no messing with file system directly, but would settle for more crude ways if need be. Specifically I am looking for: - Expunge tool: Outlook does not seem to auto-expunge messages in any way shape or form. So I'd like to run a daily cron to expunge all mailboxes. - Quota helper: Some way to send a warning email once a day or so, saying "you're close to your quota limit, please delete some mail" or somesuch Granted, I could write these two from scratch - but why reinvent the wheel? Thanks Jen

[Dovecot] Dovecot 1.0 on a Mandriva 2007 box

[Dovecot] help a journalist: What do you wish the CIO understood about fighting spam?
by Esther Schindler 30 Jan '07

30 Jan '07

Hi, folks. I'm senior online editor at CIO.com, and I'm working on an article for which I'd very much like your help. There's often a lack of communication between techies and top company management. Maybe they don't want to hear about problems; perhaps you give them technical details that are far more granular than they want to know. But dealing with spam is a topic that every e-mail admin has to cope with -- and I'm not sure that the CIO knows the real issues. I have the ear of the boss, however. Essentially, I'm trying to put together the collected wisdom of e-mail and network admins in a fashion that CIOs will understand. Or at least one teeny corner of it. So I have a very simple question to pose to you: ***If you could get your CIO (or top management) to understand one thing, just ONE thing, about fighting spam, what would it be?*** And the follow-up: why did you pick that one item? Feel free to share anecdotes, horror stories, even success stories. While I hope that every CIO will read this article, I also hope that it becomes the document you bring to a new manager ("Here: this is what's important to me"). I'm sure there are plenty of other things that you wish your CIO grokked, whether about e-mail administration or other topics (not the least of which is "the e-mail admin is underpaid"). But I do have to limit myself somehow, and "what's important about fighting spam" has a lot of leeway. I'll be sure to stop by here (as I expect others want to participate in the conversation), but feel free to cc me with your response or send me a private message. I'm hoping for a rather fast turnaround on this article, so please blurt out your first thoughts rather than plan on writing a nice, leisurely response. If all goes well, I'd like to get this article posted in the next couple of weeks. Please be sure to let me know how to refer to you in the article; the usual format is &name, &title, &company and &location ("Esther Schindler is a senior developer at the Groovy Corporation in Scottsdale Arizona"). If you give me some kind of context I'm willing to work without one. That is, I do need some identifying characteristics to give the article credibility ("Esther works at a large finance company in the Southwest").

I could also try the mbox format but Evolution has problems connection to an mbox file, it just says "loading..." and nothing happens.

[Dovecot] popa3d migration
by FiL ＠ Kpoxa 30 Jan '07

30 Jan '07

Hello, I'm sure there is no good answer to my question, but it doesn't take much to ask, so I will. I am about to migrate my current Dovecot IMAP + Popa3d mailbox server to Maildir. I need to keep both protocols (IMAP and POP3) and will be switching to Dovecot on both. The question is simple - is there any way to keep POP3 UIDs through migration, so people won't get duplicates in their inboxes. Second question is not that important but if somebody has a good answer it will be really nice - is there any way to keep IMAP UIDs? With IMAP it won't create dups, but loosing (changing) UIDs will create extra load on the server. I know, this is more about mailbox->Maildir conversion, not dovecot, but this is the only place I can ask this question P.S. am running dovecot on linux FC5 right now, but will be upgrading to FC6 / dovecot 1.0 release at the time of migration. Won't do it before 1.0 final comes out Thank you, FiL

[Dovecot] dirsize quotas crashing 1.0.rc19
by Dean Brooks 30 Jan '07

30 Jan '07

Hi, I've been trying to get dirsize quotas to work properly with 1.0rc19 and Dovecot consistently crashes when attempting to do file copies once a user is over quota. Dovecot works fine for us for regular mbox based IMAP, but as soon as I add the following two entries in their respective locations in dovecot.conf: mail_plugins = quota imap_quota (in the imap{} section) quota = dirsize:storage=2000 (in the plugin{} section) If a user goes over quota, and they attempt to copy a file to a folder via IMAP, all I get is this: dovecot: [ID 684838 mail.error] child 20868 (imap) killed with signal 10 Is anyone successfully using dirsize:storage quotas with 1.0rc19? If so, can someone else verify if they see crashes like this? As soon as I remove the quota plugin, the crashes go away and all is good, so there's obviously some sort of problem in the quota plugin.

Re: [Dovecot] repeat downloads of message headers in 1.0rc19
by James Garrison 29 Jan '07

29 Jan '07

I reported this against rc7 and rc8, and still see it occasionally. (I'm running the rc8 that comes with Fedora 5). It is always associated with this message in dovecot.log: dovecot: Oct 23 19:26:17 Error: POP3(user(a)domain.tld): mbox sync: UID inserted in the middle of mailbox /var/mail/vhosts/domain.tld/user (12 > 4, seq=2, idx_msgs=5) Once this happens, dovecot will refuse to clear out the mbox file when the user retrieves email via POP. Each time the user logs in to retrieve mail s/he gets everything in the mbox, which continues to grow. The only fix I've been able to find is to manually delete the mbox file. I'm using postfix as the MTA. -- James Garrison Athens Group, Inc. mailto:jhg@athensgroup.com 5608 Parkcrest Dr http://www.athensgroup.com Austin, TX 78731 SKYPE callto:jhg-athensgroup (512) 345-0600 x150 PGP Key ID: 0x22E8DA2A

[Dovecot] repeat downloads of message headers in 1.0rc19
by Brian G. Peterson 29 Jan '07

29 Jan '07

I upgraded one server to 1.0rc19 (from rc15) over the weekend, and have since received several reports of dovecot erroneously retrieving older messages as new mail. I've seen this myself intermittently on KMail, and users have reported it on Thunderbird, Squirrelmail, and Outlook. I see some things in the archives that suggest that this was a problem in older 1.0 release candidates, but hadn't experienced the problem myself until just now. Has anyone else seen this problem? Regards, - Brian

[Dovecot] Best small server config
by - 29 Jan '07

29 Jan '07

Hi, Busy with dovecot on a linux server with not very much RAM in it (512 MB max total). On this server dovecot will only handle about 12 users, with never more than 3 IMAP webmail users at a time, and a maximum of 2 POP3 users at a time using it. I'm going all secure later on, but first I would like your opinion on what configuration best to use with, say, max 5 users busy at one time, and have it use as little RAM and CPU as possible. (Same machine is also running httpd, squirrelmail, php5, postfix, clamd, clamsmtpd, sshd.) Here's my /etc/dovecot.conf now: # protocols = imap pop3 imap_listen = * pop3_listen = my.servers.ip.address (hidden for this list) ssl_cert_file = /etc/ssl/certs/imapd.pem ssl_key_file = /etc/ssl/private/imapd.pem ssl_parameters_file = /var/run/dovecot/ssl-parameters.dat ssl_parameters_regenerate = 320 login_dir = /var/run/dovecot-login login = imap login = pop3 default_mail_env = maildir:/home/%u/Maildir mailbox_idle_check_interval = 40 mail_full_filesystem_access = yes login_user = dovecot login_process_size = 64 login_process_per_connection = no login_processes_count = 4 login_max_processes_count = 4 login_max_logging_users = 5 max_mail_processes = 140 imap_process_size = 192 pop3_process_size = 64 first_valid_uid = 500 last_valid_uid = 520 mail_cache_fields = MessagePart mbox_locks = fcntl mbox_read_dotlock = no mbox_lock_timeout = 380 auth = default auth_mechanisms = plain auth_userdb = passwd auth_passdb = pam auth_process_size = 64 auth_user = root # Any insight or advice welcomed!

[Dovecot] Benchmarking
by Timo Sirainen 29 Jan '07

29 Jan '07

I wasted too much time today doing this, but they do show a few interesting things: 1) mmap_disable=yes is faster than mmap_disable=no. I didn't expect this. I'm not yet sure why this is, but possibly because then it updates the mail index by reading the changes from dovecot.index.log, instead of reopening and re-mmaping dovecot.index. At least that's the biggest difference between them. 2) Dovecot is faster than Cyrus, at least in test. I didn't really expect this either, because with maildir Dovecot has to do extra rename() calls for all flag changes. I'm guessing it's expunges that are slowing Cyrus down the most (that causes it to rewrite its cache file). 3) fsync_disable=yes + mmap_disable=yes almost doubles the performance with 1 client, and over quadruples the performance with 10 clients. Why fsync_disable=yes + mmap_disable=no doesn't give that big of a performance difference? I've no idea. This is anyway such a large performance increment that I'll probably go and backport this setting to v1.0 too :) 4) Dovecot's mbox code kicks maildir's ass. 5) dbox is surprisingly slow. I'll have to find out why. I don't think it should be that slow. 6) Courier.. Well, it probably doesn't come as a shock that Dovecot is almost twice as fast. Note that Courier doesn't call fsync(), so it can't be compared to Dovecot's fsync_disable=no numbers or to Cyrus. Oh, one other difference between Courier and others was that it didn't support LITERAL+ extension, so it maybe could have done a bit less appends than others. 7) CVS HEAD and branch_1_0 don't seem to have that big of a performance difference. All the tests were done using my IMAP tester: http://dovecot.org/tools/imaptest.c The mailbox data that was being appended was Dovecot's mailing list: http://dovecot.org/archives/dovecot.mbox The linefeeds were converted to CR+LF. However, for the Dovecot CVS HEAD runs the mails contained also those extra X-UID, Status, etc. headers which I had to remove before Cyrus would accept them (the lines didn't contain CRs). So CVS HEAD was actually doing a bit more work than the others.

[Dovecot] POP3 logging in wrong timezone
by - 27 Jan '07

27 Jan '07

I have dovecot running on a CentOS 4.4 server, and it is logging IMAP entries just fine, in the right timezone (GMT+1), which the server itself is running on (CET), but pop3 is being logged in GMT 0, so 1 hour too early. pop3 log-entries are at the right position in the maillog, but with the wrong time next to it. Now I've read some messages in this list about this bug (or feature), but have no clue as to how to solve it. Anyone? Thanks in advance, Ben

[Dovecot] Advice, Converting a Live/Production server.
by Michael Dilworth 26 Jan '07

26 Jan '07

I want to mess with a live server. (a Bad thing). I have googled until my eyes boogled, wiki'ed until my fingers are wonked, have read as much as I can read, however I'm left with a few questions/worries. Issue: I am currently running Dovecot as a pop3 server with standard /var/mail mbox's I would like to run a mixed Imap/Pop3 server with ~/maildir inbox's The thread http://www.dovecot.org/list/dovecot/2006-February/011304.html is fairly close to what I want to do, but I would like to go ahead and convert to maildir. (Mixed pop3/imap access for each user) I don't have a system to test, "I used have one but it's now the production server... PW/Disk failed, thank G-D(s) for rsync/backups". Setup: procmail, dovecot 1.0 beta 8.2 (fc5), squirrelmail. all users use outlook (2000,2003) or outlook express (random versions) (^^^^ not my choice, I just have to deal with it {and use it} ^^^^^) the majority of users will continue to use pop3, however some would like to convert to imap and have all mail stored on the server. Questions: /etc/procmailrc? just set default to ~/maildir? do I need to define "INBOX"? aka $MAILDIR=~/maildir/, $ORGMAIL=~/maildir/, $DEFAULT=~/maildir/ Same as above, what about new/cur should I set up a /etc/skel? close to above, if I create rules, for spam, etc. do I need to worry about cur/new. close to above, what about Sent Items, Drafts etc... for imap users, I do understand that client rules would likely be needed to store sent items. conversion, anything to look for? mb2md seems to work, but some users have "don't delete from server set", will they get dups? (I can live with this) archiving, can I (or a script) mess with the files in the maildir? aka keep the number of files/messages less than 16k for the outlook users. Bugs, should I cool my heals, and wait for rc16 or 1.0 final? I am currently running problem free, and I do hate to mess with something which is not busted. TIA Michael.

[Dovecot] Dovecot POP3 fails to chdir under FC6
by James A. McDonald 26 Jan '07

26 Jan '07

I started the Dovecot POP3 server under Fedora Core 6 (rpm dovecot-1.0-1.1.rc15.fc6), but some users couldn't connect, with /var/log/maillog show the message Jan 24 13:20:00 mmace dovecot: chdir(/branch/home/mmace) failed with uid 205: Permission denied Jan 24 13:20:00 mmace dovecot: child 18792 (pop3) returned error 89 (I had already edited first_valid_UID in /etc/dovecot.conf to allow UID's >= 200.) However, only users who had their home directory under /branch/home couldn't connect. Users with homedirs under /home connected via POP3 just fine. I found out POP3 connection failures also logged an error to /etc/messages: Jan 24 13:20:00 mmace kernel: audit(1169662800.479:160): avc: denied { search } for pid=18792 comm="dovecot" name="/" dev=sda3 ino=2 scontext=system_u:system_r:dovecot_t:s0 tcontext=system_u:object_r:mnt_t:s0 tclass=dir So, selinux was the culprit. My home directories had the right selinux security context, but the root of the disk holding those home directories (/branch is a separate disk drive) had a security context (system_u:object_r:mnt_t) that Fedora's selinux rules for dovecot did not allow. I changed the context of /branch to system_u:object_r:usr_t, and dovecot POP3 access worked for all users.

[Dovecot] X-UID gaps cause Dovecot/IMAP to hang
by Benjamin Howell 25 Jan '07

25 Jan '07

Hi, When the Dovecot 1.0.rc19 IMAP server encounters X-UID headers with gaps in them, it hangs indefinitely. I've attached a sample mailbox (in mbox format) which repeatably exhibits this behavior. The mbox contains only three messages with the following X-UIDs in order: 774, 785, 787. If I remove the X-UID headers from each message, Dovecot handles the mailbox without any problems. UW-IMAP is able to handle the sample mbox _with_ X-UID headers. A full backtrace is also included. When Dovecot hangs, it appears to continually lock and unlock the mailbox. I'm using dotlocking so a mailbox.lock file appears and disappears constantly. I have to kill the process to log back in. I'm not familiar enough with Dovecot to offer a patch, but if anybody feels they can fix this or needs more information, please let me know. Regards, Benjamin Howell bhowell(a)iglou.com

Hello, Is it possible with dovcot (rc7) to log how long it takes to complete downloading mail? If so, what do I have to set in the conf file? Thank you! -- Zbigniew Szalbot

[Dovecot] rc18->rc19: read/unread/reply flags broken
by Jeff A. Earickson 25 Jan '07

25 Jan '07

Timo, This might be a bit vague, but I have noticed that rc19 seems to have broken the read/unread/reply flags in imap. My officemate has had problems with messages that are read and marked as read then mysteriously get remarked as unread the next time email is checked. I've had problems where I reply to a message and it does not get marked as "answered". We didn't see this with rc18 and earlier. My setup: Solaris 10, sparc, T2000 system. rc19 (now back to rc18), using mbox format. system mailbox is NFS mounted from another Sun Solaris 10 system, homedirs and dovcot cache files are on local zfs filesystems.

Re: [Dovecot] X-UID: 4085788205 != 2147483647

Afterwards even if user expunges all the messages, there are two things that prevent this from being possible: index files and the UW-IMAP style "FOLDER INTERNAL DATA" message. You could also prevent this completely by stripping the X-UID header in your SMTP server or LDA. For example Dovecot LDA strips all the Dovecot's internal metadata headers. I guess the UID renumbering could be done some day, but for now I think it's just way too much trouble with not that much benefits.

[Dovecot] dovecot LDA 'deliver' and aliases
by Michael Pulk 25 Jan '07

25 Jan '07

Dovecot LDA (deliver) aliases question. I have a multiple virtual domain setup using sendmail, username/domain, password, home directory all stored in mysql,Set-UID/GID for dovecot 'deliver' setup as referenced in Dovecot LDA wiki. Delivery, and POP/IMAP work just fine, serving a mail store in /home/vmail/domain/username type of setup. My problem comes from what may be a misunderstanding on my part on how to setup aliases for some virtual users. I have the mailer specification for dovecot defined, and my mailertable and (access) tables setup for each domain, with an entry like this for each domain in mailertable: domain.com dovecot:dovecot and since I also function as SMTP relay for each customer, I also have an entry in in access domain.com RELAY and the tables are made with hash... this all appears to work just fine, except when I want to alias a certian email address. Lets say that I have one email in the domain that needs to be forwarded to another remote account (on another server), I would normally accomplish this with an entry in virtusertable something like this: sales(a)domain.com <mailto:sales@domain.com> user(a)otherdomain.com <mailto:user@otherdomain.com> but when using dovecots' deliver as the LDA specified for domain.com in mailertable, this appears to be ignored, with the email being returned undeliverable (if sales(a)domain.com <mailto:sales@domain.com> doesn't exist), or being delivered to sales(a)domain.com <mailto:sales@domain.com> (if the account exists in the mysql table). I have also tried creating the account, and placing a .forward file in the appropriate /home/vmail/domain/user directory, but this also appears to be ignored. Does anyone have some advice on how to implement such an ability? I am running dovecot-1.0.rc17, sendmail-8.13.1-3.RHEL4.5, mysql-4.1.20-1.RHEL4.1 on Centos 4.4 Sincerely Michael P.

[Dovecot] NEWBIE: configuring all virtual users...
by AJ Weber 24 Jan '07

24 Jan '07

OK, I'm trying to filter-through all the different WiKi and docs about how to configure all virtual users. Now, there's only going to be a few, and it's a secure env, so I'm going to try and configure a custom passwd file (or whatever trimmed-down version I can do), basically to do usernames, passwords, and MBOX dirs. I'm only planning on serving POP3 mail to my clients. I have a location to create MBOX files -- it will be in a specific directory, with sub-dirs for each user; sort of a /home/VU/%u/mbox . I'm really confused as to what add'l info I need to include like "INDEX" and "INBOX" on the mail_location info. Does anyone have any info and/or examples on how to configure my .conf file and create a minimal passwd file for these virtual users? Thanks in advance, AJ

[Dovecot] pop/imap login logging only username part of full email address
by Justin McAleer 24 Jan '07

24 Jan '07

I have my login log format set like so: login_log_format_elements = user=<%u> method=%m rip=%r lip=%l %c When I log in using a full email address, though, I only get the username part of the address: Jan 24 13:28:29 node7 dovecot: pop3-login: Login: user=<justin>, method=PLAIN, rip=137.118.2.60, lip=137.118.7.247 Jan 24 13:28:30 node7 dovecot: POP3(justin): Disconnected: Logged out top=0/0, retr=0/0, del=0/717, size=15797460 Is that behavior intentional? If so, can it log the full username as given by the client instead? Anyone with multiple domains probably wants to see the domain part. Changing %u to %n yields the same log entry, and %d seems to be empty so nothing gets logged if I try to log that.

[Dovecot] More AFS maildir debugging
by Aaron Solochek 24 Jan '07

24 Jan '07

There appears to be some sort of a race condition when accessing a maildir directory for the first time with dovecot. I was getting a non-specific error trying to select INBOX, but when I stepped through it with a debugger it worked. Deleting the dovecot files and running the select again it failed. I started playing with it again just now, and when attempting to access Sent, I actually got some errors: a04 select Sent imap(aarons): Error: Corrupted transaction log file /XX/Maildir/.Sent/dovecot.index.log: unexpected end of file while reading header imap(aarons): Error: Corrupted transaction log file /XX/Maildir/.Sent/dovecot.index.log: unexpected end of file while reading header imap(aarons): Error: Corrupted transaction log file /XX/Maildir/.Sent/dovecot.index.log: unexpected end of file while reading header a04 NO Internal error occurred. Refer to server log for more information. [2007-01-13 16:17:51] I then deleted dovecot.index.log and dovecot.index.log.2 (the only two dovecot files that were present) and retried the select: a04 select Sent a04 NO Internal error occurred. Refer to server log for more information. [2007-01-13 16:23:40] Does anyone more familiar with the code than myself have any pointers of where to concentrate my debugging efforts? Thanks. -Aaron

[Dovecot] dovecot-acl file location in rc18
by Radek Zavicak 24 Jan '07

24 Jan '07

Hi, I'm trying to use ACL with dovecot rc18 but I don't understand where to store per-mailbox dovecot-acl file. In dovecot.conf I have mail_location = maildir:/var/vmail/%u/ and I do not use namespaces. I have some "testuser" maildir with subdir ".test". When I put dovecot-acl file to the .test directory I get this error in my log file: Error: IMAP(testuser): /var/vmail/testuser/.test/dovecot-acl is no longer kept in control directory, move it to the actual maildir (/var/vmail/testuser/.test) Error: child 28143 (imap) returned error 89 This error tells me to move dovecot-acl file from control dir to mail directory but these are the same for me (and I think it's Dovecot default for maildir). Where I should store per-mailbox dovecot-acl file in this case? Regards, Radek Zavicak

[Dovecot] too many open files error when using quota plugin
by Justin McAleer 24 Jan '07

24 Jan '07

With the quota plugin loaded (even with a quota value of 0), I get errors like the following: open(/var/mailstore/01/1a/301620/Maildir/cur/1169654988.P22440Q0M696852.<hostname stripped>,S=4437552:2,Sbc) failed: Too many open files To do this, I have a folder with about 700 messages and I tell Thunderbird to run junkmail controls on it (fetches all messages). Watching an strace on the imap process I'm connected to, the problem seems to be when the plugin goes to close the maildirsize file, it's not closing the correct file descriptor: open("/var/mailstore/01/1a/301620/Maildir/./maildirsize", O_RDWR|O_APPEND) = 1016 read(1016, "1024S\n395 1\n397 1\n", 5120) = 18 read(1016, "", 5102) = 0 close(4294967295) = -1 EBADF (Bad file descriptor) It closes that same descriptor every time. On a side note, I'm just curious why it needs to read the maildirsize file for a fetch request anyway?

[Dovecot] dovecotpw/sql crypt scheme core dump with rc17-19
by Andre Dalle 24 Jan '07

24 Jan '07

Platform is Solaris 8 on a 280R. I'm setting up a new installation of Dovecot, and I ran into some troubles that I've partly tracked down. I setup auth/user dbs with LDAP initially, and things worked well. Passwords are stored as "{crypt}zxcv..." in LDAP. I setup SQL, and began getting this: dovecot: Jan 23 16:37:47 Error: child 8718 (auth-worker) killed with signal 11 Passwords are stored as "zxcv..." in SQL. I changed default_pass_scheme from CRYPT to PLAIN, and no troubles. I then tried dovecotpw: dovecotpw -p 123 -s PLAIN-MD5 {PLAIN-MD5}202cb962ac59075b964b07152d234b70 dovecotpw -p 123 -s CRYPT Segmentation Fault (core dumped) So I then tried this: truss dovecotpw -p 123 -s crypt open64("/dev/urandom", O_RDONLY) = 3 read(3, "F80E82 c", 4) = 4 fcntl(3, F_GETFD, 0x00000000) = 0 fcntl(3, F_SETFD, 0x00000001) = 0 open64("/usr/local/lib/dovecot/auth/password", O_RDONLY|O_NDELAY) Err#2 ENOENT read(3, "8382", 2) = 2 Incurred fault #6, FLTBOUNDS %pc = 0xFF0E3304 siginfo: SIGSEGV SEGV_MAPERR addr=0x00000005 Received signal #11, SIGSEGV [default] siginfo: SIGSEGV SEGV_MAPERR addr=0x00000005 *** process killed *** Suffice to say, there is no "/usr/local/lib/dovecot/auth/password".

[Dovecot] All index file bugs fixed(?)
by Timo Sirainen 23 Jan '07

23 Jan '07

I fixed the nightly snapshot building. Now it's again being built every night (if there have been any changes). Please test it before I'll make rc18 release. http://dovecot.org/nightly/dovecot-latest.tar.gz I've also been stress testing a lot with http://dovecot.org/tools/imaptest.c. Last night I ran it for 9 hours with mmap_disable=yes and it picked up only one race condition, which is also now fixed. I'll run the next night with mmap_disable=no and see if anything shows up with it. I'm hopeful that there aren't any important index file related bugs left anymore. This is actually the first time in Dovecot's existence that I'm really not aware of *any* bugs in index file handling. v1.0 release should be really near now, unless you figure out new problems :) Here's a list of bugs that should have been fixed since rc17: "Corrupted index file dovecot.index: Record field keywords points outside record size (12 < 12+2)" "Corrupted Index file dovecot.index: Record [1].uid=0" Crashes - http://dovecot.org/list/dovecot-cvs/2007-January/007395.html "open() failed with file dovecot.index.log: No such file or directory" - http://dovecot.org/list/dovecot-cvs/2007-January/007405.html "Fixed index file dovecot.index: seen_messages_count 8 -> 9" "View synchronization from transaction log failed: Deleted counter wrong" etc. - http://dovecot.org/list/dovecot-cvs/2007-January/007403.html Corrupted transaction log errors: - http://dovecot.org/list/dovecot-cvs/2007-January/007389.html - http://dovecot.org/list/dovecot-cvs/2007-January/007393.html Corrupted view errors: - http://dovecot.org/list/dovecot-cvs/2007-January/007366.html - http://dovecot.org/list/dovecot-cvs/2007-January/007368.html Corrupted cache file errors: - http://dovecot.org/list/dovecot-cvs/2007-January/007364.html Fixed a lot of crashes whenever something went wrong (I deleted index files every 3 seconds until it crashed, last run went for several minutes before I stopped trying): - http://dovecot.org/list/dovecot-cvs/2007-January/007397.html

[Dovecot] 1.0.rc18 released
by Timo Sirainen 23 Jan '07

23 Jan '07

http://dovecot.org/releases/dovecot-1.0.rc18.tar.gz http://dovecot.org/releases/dovecot-1.0.rc18.tar.gz.sig I think we're quite near v1.0 now. * ACL plugin + Maildir: Moved dovecot-acl file from control directory to maildir. To prevent accidents caused by this change, Dovecot kills itself if it finds dovecot-acl file from the control directory. * When opening a maildir, check if tmp/'s atime is over 8h old. If it is, delete files in it with ctime older than 36h. However if atime - ctime > 36h, it means that there's nothing to be deleted and the scanning isn't done. We update atime ourself if filesystem is mounted with noatime. * base_dir doesn't need to be group-readable, don't force it. * mail_read_mmaped setting is deprecated and possibly broken. It's now removed from dovecot-example.conf, but it still works for now. * Removed also umask setting from dovecot-example.conf since currently it doesn't do what it's supposed to. + Authentication cache caches now also userdb data. + Added mail_log plugin to log various mail operations. Currently it logs mail copies, deletions, expunges and mailbox deletions. - dict quota: messages=n parameter actually changed storage limit. - A lot of fixes to handling index files. This should fix almost all of the problems ever reported. - LDAP: auth_bind=yes was more or less broken. - Saved mails and dovecot-keywords file didn't set the group from dovecot-shared file. - Fixed potential assert-crash while searching messages - Fixed some crashes with invalid X-UID headers in mboxes - If you didn't have a namespace with empty prefix, giving STATUS command for a non-existing namespace caused the connection to give "NO Unknown namespace" errors for all the future commands.

[Dovecot] Current state of mulit-server NFS setups
by Justin McAleer 23 Jan '07

23 Jan '07

Hi list, I've been perusing the list archives, but I couldn't find a recent, definitive answer to what I'd like to know. I'm looking to set up a new batch of servers to migrate ~160,000 accounts, spread across several domains, onto (from CommuniGate). Last year I worked with the earlier beta/RC versions of Dovecot, so I'm generally familiar with the setup required. However, a lot of development has been done since I was last dealing with it. So, what I'd like to end up with is a load balanced group of servers providing pop and imap access with quota support using an NFS filesystem. We have a new Netapp device (forget the actual model) that can do SAN/iSCSI/NFS. We tried using various clustered filesystems previously, but the performance/stability issues were a nightmare, so I've fallen back to NFS (or perhaps SAN if users can't hit any server in the group). So, what does my dovecot setup need to be? I've seen some people say they disable indexing in the LDA, but allow pop/imap to index. Some say the attribute cache needs to be disabled, which I'd think would be worse than just disabling indexes. Some say indexes should be kept on local disk (dedicated server for users), and others seem to report problems even when doing so. Is there a general consensus? I was also wondering if dovecot's sanity checking on the indexes would allow each server in a balanced group to keep indexes on local disk (so if the maildir has changed on another server, dovecot rebuilds it). If so, does that take away all performance gains from having indexes at all? Thanks for any info you all can provide.

[Dovecot] Maildir Quota backend
by Ioannis Zachariadis 23 Jan '07

23 Jan '07

Hi, I've noticed that in the maildir backend for the quota plugin the quota limit is being read in kilobytes. In the quota-maildir.c at maildir_quota_init() , line 550 (rc18) if (strncmp(*args, "storage=", 8) == 0) { size = strtoull(*args + 8, NULL, 10) * 1024; if (size != 0) root->message_bytes_limit = size; root->master_message_limits = TRUE; } The value that's being read from storage is supposed to be in kB, at least that's what I understand from the wiki, and then the value of size is stored in bytes. thanks -- giannis.

[Dovecot] LDAP authentication stops working...
by Adrian Close 23 Jan '07

23 Jan '07

Hi all, I'm running dovecot-1.0.rc17 on OpenBSD 3.9, using userdb and passdb methods of "ldap" (SSL on 636/tcp) in addition to "passwd". Occasionally (generally after a few hours of operation, but not always), LDAP-based logins stop working (e.g. hang/timeout after POP3 PASS command). Accounts with local passwords (as opposed to accounts with a password field of "x") still work fine at this point. 'tcpdump' shows the persisient 636/tcp connection still with bidirectional traffic (PUSH/ACKs and ACKs like normal). After restarting Dovecot, things are fine until next time. I guess I could try and get login_ldap working with bsdauth, but if there's an issue in the Dovecot LDAP support I'd like to see it fixed. Any ideas? Thanks, Adrian Close P.S. I note the LDAP timeout logging patch but it won't apply easily to rc17 and I'm hoping the issue has progressed since then anyway...

[Dovecot] X-UID: 4085788205 != 2147483647
by Stephen Gowing 23 Jan '07

23 Jan '07

Hi, Dovecot (at least versions 0.99.10.4, 0.99.11, 1.0rc15, rc17 and rc18) allows message Unique Identifiers to be an unsigned 32 bit value, so something like "X-UID: 4085788205" is allowed. Some IMAP clients I've tested (Thunderbird 1.5.0.9, SquirrelMail 1.4.9a/PHP 4.3.2) appear to use signed 32 bit identifiers and request the above message as UID 2147483647 (max signed 32 bit integer). Evolution 2.0.2 fetches 4085788205 without complaint. Is there any chance Dovecot could decide to invalidate and renumber a folder when identifiers greater than 2147483647 are found? sbg

[Dovecot] mysteriously disappearing RECENT flag
by Vadim Zeitlin 22 Jan '07

22 Jan '07

Hello, I've decided to switch from UW-IMAP to Dovecot and so installed 1.0.rc15-2 on a Debian/Etch system and started using it with the existing MBOX folders. My configuration is pretty much the default one, in particular I didn't touch to any of mbox_xxx options. The (hoped for) performance improvements were indeed quite noticeable and mostly it works just fine but I seem to have one strange problem with the recent messages: Dovecot seems to reset the RECENT flag on the message right *before* the mailbox is opened. So even if a message was just copied to a folder (e.g. by email client filtering), it doesn't have RECENT flag when the mailbox is opened. Here is an example of what I see: % telnet localhost 143 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. * OK [CAPABILITY IMAP4rev1 SASL-IR SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN NAMESPACE LOGIN-REFERRALS STARTTLS AUTH=PLAIN] Dovecot ready. 1 login user password 1 OK Logged in. 2 status test (messages recent unseen) * STATUS "test" (MESSAGES 41 RECENT 0 UNSEEN 0) 2 OK Status completed. [--- switch to another window and copy a message to the test folder ---] 3 status test (messages recent unseen) * STATUS "test" (MESSAGES 42 RECENT 1 UNSEEN 0) 3 OK Status completed. 4 select test * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 42 EXISTS * 0 RECENT * OK [UIDVALIDITY 1048987099] UIDs valid * OK [UIDNEXT 407] Predicted next UID 4 OK [READ-WRITE] Select completed. 5 status test (messages recent unseen) * STATUS "test" (MESSAGES 42 RECENT 0 UNSEEN 0) 5 OK Status completed. 6 fetch 42 flags * 42 FETCH (FLAGS (\Seen)) 7 logout * BYE Logging out 7 OK Logout completed. Connection closed by foreign host. Why does Dovecot send "0 RECENT" when the mailbox is opened when it had just told that there was a recent message in it? And why is the message effectively old (no \Recent in the FETCH reply)? Notice that if I look at the MBOX file I see "Status: R" until command number 7, it becomes "Status: RO" only when I log out -- but internally Dovecot clearly considers it to be old long before that. Am I doing something wrong? Or is this the expected behaviour and, in this case, is there any way to change it to the more expected one (UW-IMAP-like)? Thanks in advance, VZ

[Dovecot] Message size incorrect?
by Tristan Woudenberg - Prism Mail Solutions 20 Jan '07

20 Jan '07

Hi there, I recently installed a plugin for SquirelMail (php imap client, squirrelmail.org) which adds up message sizes per folder to display a nice total size of each subscribed folder. After consulting the plugin maintainers at SquirrelMail in this thread: http://thread.gmane.org/gmane.mail.squirrelmail.plugins/12468/focus=12468 There is quite a discrepancy in the rfc822.size reported by Dovecot and the actual space it takes up on my harddisk. I know there could be some overhead here from all the dovecot* and subscription list files in my imap folders, but like I stated in my email to the SquirrelMail plugin mailing list, about 1mb for a 4.3mb maildir mailbox might be a but much. Could this be like Tomas Kuliavas wrote: "Maybe those message have some data that does not belong to message or their formating breaks dovecot's message parsing functions."? I'm using Dovecot-1.0.rc15, sorry if this has been fixed between this release and the current. Kindest regards, Tristan -- Prism Mail Solutions Deployment, customization and hosting http://prism.nl

I hope this helps. > If there is anything else I can provide to shed more light, let me know. login_processes_count = 32 This means that Dovecot always keeps extra 32 login processes that don't do anything else than wait for new connections. That's not at least helping :) Anyway, I'd like to get lsof of an imap-login process that is doing SSL proxying. Unfortunately I don't think there's any simple way to know what processes are doing that and what aren't. Setting login_process_count=1 at least makes it more likely that you'll hit the right process. If trussing the process shows that it's writing some garbage to file descriptor 1, it's probably proxying SSL..

[Dovecot] stale locks
by Thomas Hummel 20 Jan '07

20 Jan '07

Hello Timo, I'm running dovecot-1.0.rc15 (imap and pop) postfix-2.3.5,1 procmail-3.22_6 (which is my LDA) on FreeBSD 6.1-STABLE I'm still using the mbox format (I'm planning to migrate to Maildir soon), mailboxes are on an NFS filesystem. I regulary see stale dotlocks files (either from dovecot (29 bytes, hold the pid of the process) or procmail (1 byte) and processes stucked in Disk Wait state. The only way I can get ridd of them is to restart nfslocking remove the .lock file change the inode of the mailbox file locking strategies are fcntl for mbox_read in dovecot dotlock fcntl for mbox_write in dovecot dotlock fcntl for procmail so I can't figure out why I see such stale locks and processes. Note : I disabled nfs attribute caching so I avoid cache related issues (such as a dotlock showing up late, etc...) Besides, I often see several imap-login processes for the same remote IP address. Does it means the user has several instances of his UA running or is it the behavior of some UA (Eudora ? Thunderbird ?) even if only one instance is run by the user. In any case, wouldn't that be dead-lock/stale lock prone ? -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] Disconnects with proxies
by Michael Kress 20 Jan '07

20 Jan '07

Hi, I know I shouldn't ask stuff like this when using dovecot-0.99.11-4.EL4 (CentOS-4.4), but why I'm asking this is whether it's worth to switch from rpm based upstream dovecot to a self compiled one or not and thus I think you wouldn't kill me presenting you this question. o:-) I've got a problem with dovecot regarding a pop3 proxy issue. When I configure my dovecot server to do just plain pop3 I can telnet from a windows box without any flaw, but as soon as the client uses some pop3 proxy (for example outlook uses avira antivir Mail-AntiVirus Protection), queries to that server fail. A log line looks like this: pop3-login: Dec 05 22:53:24 Info: Disconnected [::ffff:84.165.54.42] Moreover with the proxy activated, a telnet to port 110 (pop3) is not working properly, the cursor stays right behind "+OK dovecot ready." and as soon as I enter a character, the server rejects this character as an unknown command (Without pressing ENTER). As soon as I turn off the Antivir-Proxy the telnet to port 110 runs flawlessly and I can login. So I'd like to know is there anything I can do with this version or is it worth trying the newest version? Is this a known issue?

[Dovecot] Bug Report: ACL plugin searches wrong directory with shared folders
by Garret Huntress 19 Jan '07

19 Jan '07

I've been attempting to get to get Shared Folders and ACL's to work under dovecot 1.0rc17. Unfortunately, I've run into some problems (many have already been mentioned on the list), specifically the problem where folder-specific ACL files are not found (and I will not use Global ACL's due to the 100% probability of cross-namespace mailbox name conflicts). My namespace is as follows: namespace private { separator = / prefix = location = maildir:%h/Maildir inbox = yes } namespace private { separator = / prefix = CIW Archived/ location = maildir:%h/Mailarchive } namespace public { separator = / prefix = CIW Groups/ location = maildir:/srv/export/groups:CONTROL=%h/Maildir/public- subscriptions:INDEX=%h/Maildir/public-index } I decided to run a quick strace on dovecot's imap daemon while I was getting a folder listing to see why dovecot was not finding the folder-specific ACLs. Below are what I feel are the two key instances in the trace: Example 1: searching for ACL on private folder open("/etc/dovecot-acls//.DEFAULT", O_RDONLY) = -1 ENOENT (No such file or directory) open("/home/ghuntress/Maildir/./dovecot-acl", O_RDONLY) = -1 ENOENT (No such file or directory) open("/etc/dovecot-acls/Work", O_RDONLY) = -1 ENOENT (No such file or directory) open("/home/ghuntress/Maildir/.Work/dovecot-acl", O_RDONLY) = -1 ENOENT (No such file or directory) stat("/etc/dovecot-acls/", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0 open("/etc/dovecot-acls/", O_RDONLY) = 7 That looks good. The ACL plugin looking for the global acls first in the correct location, then in the maildir itself for the folder- specific acl. Example 2: searching for ACL on shared folder open("/etc/dovecot-acls//.DEFAULT", O_RDONLY) = -1 ENOENT (No such file or directory) open("/home/ghuntress/Maildir/public-subscriptions/./dovecot-acl", O_RDONLY) = -1 ENOENT (No such file or directory) open("/etc/dovecot-acls/IS.Postmaster", O_RDONLY) = -1 ENOENT (No such file or directory) open("/home/ghuntress/Maildir/public-subscriptions/.IS.Postmaster/ dovecot-acl", O_RDONLY) = -1 ENOENT (No such file or directory) stat("/etc/dovecot-acls/", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0 open("/etc/dovecot-acls/", O_RDONLY) = 7 Not so good. The ACL plugin is looking under the "CONTROL=" setting from the namespace location configuration, and not under the maildir itself for the folder-specific acl. Since we have to set the separate CONTROL location because of subscription conflicts (http:// wiki.dovecot.org/SharedFolders) we either break subscriptions by removing the CONTROL setting, or break ACL's by adding it. I'm not terribly familiar with the inner workings of Dovecot, however I can envision two possible fixes: 1.) Always have the ACL plugin look under the maildir location (and not the CONTROL override) for folder-specific ACLs or 2.) Have dovecot always place subscriptions for shared folders in a user-specific directory regardless of the namespace location configuration (although, this would probably break a ton of production configurations). I don't know what either of the above options would break, but I hope it's gives some ideas on how to fix this long-standing bug. Please let me know if I can be of any more help. -Garret -- Garret W.

[Dovecot] quota in mysql not being updated
by Marshal Newrock 19 Jan '07

19 Jan '07

I'm having trouble getting the quota plugin to work with deliver. The quota in the database is not getting set. I am using dovecot-1.0-rc15. This server is not yet in production.

[Dovecot] Authorization client connect failing
by Ryan Hinton 19 Jan '07

19 Jan '07

Hello, and thank you in advance for your valuable time. I am running Dovecot v1.0.rc15 on an OpenBSD 3.9 i386 machine (no time to upgrade yet). I downloaded the source from the dovecot site, compiled and installed without any problem. The server starts up find and runs for a while. After a few hours to a few days, the server stops sending the CAPABILITY statement when a client tries to login. I found a few descriptions of this problem on the web, but no satisfactory resolution. I added some debugging code to the functions in auth-client.c and got the following traces. Included in this email are a successful login attempt, a failed attempt, and a startup trace. I am not a UNIX sockets guru and don't know the dovecot internals well enough to figure out what's wrong. I am happy to add/remove debugging code as requested to help track down the problem, although it may take a few days for the server to hang again. I hope someone can help me figure out the problem so my mail server works reliably! Here is a successful login attempt. Dec 9 10:34:45 myhost dovecot: imap-login: DEBUG:: auth_client_is_connected?

[Dovecot] Connection to server time out when deleting (moving to Trash)
by Anders Lund 19 Jan '07

19 Jan '07

Hi, Running: * Dovecot 1.0 rc15 * Debian Sarge Linux Using Maildir and IMAP over SSL. When trying to delete a lot of mail (> 5000-6000 messages) in some folder, using Mozilla Thunderbird (1.5.0.7) on Ubuntu, I often experience "Connection to server <hostname> timed out." Any suggestions on how to fix this problem? "Empty Trash" seem to work fine, so I guess this is related to moving a lot of mail from one folder to another (Thrash)? - Anders -- Anders Lund <Anders.Lund(a)uninett.no> .~.

[Dovecot] Virtual Users and Local Users Authentication
by craig carriere 19 Jan '07

19 Jan '07

I am using dovecot on a SLES 10 mail server using postfix as the MTA. The original setup used local users and a single domain. I have now configured postfix to send mail to a second virtual domain which is working fine. I am trying to get dovecot to pick up the mail and have been having authentication problems. My local users uses pam and /etc/passwd for login with SSL. I have created a passwd file for the virtual users and have set dovecot to look at the passwd-like file with the path specified. However dovecot complains about the file not being present, which it is and my local users can not login. Probably doing something simple incorrectly, but can not find what fron online searches.

[Dovecot] Migrating from UW-IMAP
by Jay Chandler 19 Jan '07

19 Jan '07

Greetings. I've got a poorly conceived and implemented system I'm trying to migrate off of. Right now we've got 20K accounts or so, in mbox form, under UW-IMAP. Eventually we're going to move to Maildir format, but the first step is to move to Dovecot on one of our imap servers as a proof of concept. In other words, all config changes have to take place on the dovecot side, until I get PHB approval to proceed further. Right now, the inboxes are the user's username, located in /var/mail (an NFS mounted volume). So my inbox would be at /var/mail/chandler. The sub-mailboxes are in the user home directories, just scattered around-- no /mail subdirectory or anything close. So there's a folder called ~chandler/INBOX.Sent, ~chandler/INBOX.Trash, and a ~chandler/Dovecot (for this list). The list of these files is kept in ~chandler/.mailboxlist. I attempted to follow the instructions at http://wiki.dovecot.org/Migration about: You can either rename your .mailboxlist file to .subscriptions for all your users using uw2dovecot.sh <http://wiki.dovecot.org/uw2dovecot.sh>, or change the definition of SUBSCRIPTION_FILE_NAME in /src/lib-storage/subscription-file/subscription-file.c/. In 1.0-test, this value is defined in /src/lib-storage/subscription-fileindex/maildir/maildir-storage.h/ and /src/lib-storage/subscription-fileindex/mbox/maildir-storage.h/. .subscriptions is located inside of the mail directory, whereas it is possible .mailboxlist was outside of it (in user's home directory). However, I built dovecot from ports on FreeBSD 6.2, and the only files that approach this are: wurfel# ls -al total 58 drwxr-xr-x 3 root wheel 512 Jan 16 20:48 . drwxr-xr-x 6 root wheel 1024 Jan 16 20:48 .. drwxr-xr-x 2 root wheel 512 Jan 16 20:48 .deps -rw-r--r-- 1 root wheel 14662 Jan 16 20:48 Makefile -rw-r--r-- 1 root wheel 266 Oct 20 2004 Makefile.am -rw-r--r-- 1 root wheel 14009 Jan 6 23:26 Makefile.in -rw-r--r-- 1 root wheel 4374 Jan 16 20:48 libstorage_subscription_file.a -rw-r--r-- 1 root wheel 6935 Jan 3 15:19 subscription-file.c -rw-r--r-- 1 root wheel 703 Jan 13 2006 subscription-file.h -rw-r--r-- 1 root wheel 4060 Jan 16 20:48 subscription-file.o wurfel# pwd /usr/ports/mail/dovecot/work/dovecot-1.0.rc17/src/lib-storage/subscription-file I took a look at subscription-file.c, but didn't notice where I should change the definition of the file itself-- my code-fu is weak. If someone could lend a hand, I'd be deeply appreciative.

[Dovecot] Bounce vs. Defer
by Jeff Mitchell 19 Jan '07

19 Jan '07

Hello-- I've noticed that with when using deliver, if there is a misconfiguration in my dovecot configuration file, a permissions problem on the maildir, etc., deliver will bounce the message. I'm using Postfix, and at some point used Maildrop, and I know that maildrop (and I believe also Postfix's virtual transport) instead defer the message if there is some kind of fixable problem (like permissions). Then, when the problem is solved, you can flush the queue. Would it be possible to add a defer option to deliver? It makes it difficult to try out new options or different configurations because if you have fairly regular incoming mail, the last thing you want is a ten minute period where 20 messages get bounced... Thanks, Jeff

[Dovecot] dovecot as POP3 proxy

Hello, I am trying to set up dovecot as pop3 proxy. There is net lines in my auth section: passdb passwd-file { args = /usr/local/etc/dovecot/proxy.users } userdb static { args = uid=26 gid=6 } File proxy.users should contain a list of users. Now it looks like test:::::::proxy host=10.10.10.10 and everything is OK. My question is how to change passwd-file in order to match any username? I need something like *:::::::proxy host=10.10.10.10 Thanks in advance! -- Kind Regards, Alexander Shikoff

[Dovecot] FreeBSD, Postfix, Cyrus SASL, Dovecot IMAP, SquirrelMail, Active Directory
by Phil Anslemo 19 Jan '07

19 Jan '07

Here's an update to my configuration. I'm able to use Cyrus SASL to enable SMTP AUTH in PostFix, validate user's mail addresses in Active Directory, and store mail in maildir on FreeBSD. I am currently able to authenticate AD users with Dovecot and LDAP, but I'm getting the following error in the log: Error: IMAP(user@domain): Ambiguous mail location setting, don't know what to do with it: user@domain (try prefixing it with mbox: or maildir:) Error: IMAP(user@doman): Failed to create storage data: user@domain. Error: child xxxxx (imap) returned error 89 I double-checked dovecot.conf, and the mail_location setting is "mail_location = maildir:/usr/data/vmail/%u". I'm not sure what could be happening, but I'm thinking this is the last thing I need to get my configuration to work. Your assistance is greatly appreciated.

[Dovecot] Build problems with non-standard location of mysql libs
by Bob 19 Jan '07

19 Jan '07

Overall the build process for dovecot is very clean. I did however run into a significant problem when it came to locating the mysql libraries, especially when building a 64 bit executable but similar problems occured building a 32 bit executable. I am describing the 64 bit build issues below since that is the worst case scenario. Fixing the 64 bit build will automatically fix the 32 bit build. In the Solaris world it is fairly common for software packages to be installed in the /opt tree rather than under /usr or /usr/local. In addition 64 bit libs are typically located under a path like /opt/lib/64 or /opt/lib/sparcv9 and of course mysql libs are under /opt/lib/mysql or /opt/lib/sparcv9 | 64/mysql. The configure script for dovecot tries only a lib64 or /usr/lib64 path I suggest that the conifgure script for dovecot offer a --with-mysql[=DIR] option so that it would be possible to provide the base location of the mysql installation as --with-mysql=/opt in the same manner that it is done for php. I patched the configure script to search the /opt tree for mysql but unfortunately a side effect occured during the build which was compiled as 64 bit with the necessary CFLAGS and LDFLAGS input to the configure script. Here is the configure. Note that the library search paths also include the Solaris specific sparcv9 paths so nothing special is required in the configure script to account for these platform specific paths. This is exactly the same method the we use to build php as a 64 bit app successfully. However, the configrue script needs to locate the /opt/include/mysql directory and also needs to find /opt/lib/mysql to at least trigger that it found the mysql installation. Even though /opt/lib/mysql is the path to the 32 bit library, the link tests will pass because the supplied LDFLAGS contain the path to the 64 bit library. CFLAGS="-O3 -m64 -mcpu=ultrasparc -L/opt/lib/sparcv9 -L/opt/lib/sparcv9/mysql -R/opt/lib/sparcv9 -R/opt/lib/sparcv9/mysql" \ CXXFLAGS="-O3 -m64 -mcpu=ultrasparc -L/opt/lib/sparcv9 -L/opt/lib/sparcv9/mysql -R/opt/lib/sparcv9 -R/opt/lib/sparcv9/mysql" \ LDFLAGS="-O3 -m64 -mcpu=ultrasparc -L/opt/lib/sparcv9 -L/opt/lib/sparcv9/mysql -R/opt/lib/sparcv9 -R/opt/lib/sparcv9/mysql" \ ./configure --prefix=/opt \ --localstatedir=/var \ --enable-shared \ --disable-static \ --libdir=/opt/lib/sparcv9 \ --with-ssldir=/opt/ssl \ --with-ssl=openssl \ --with-storages=maildir,mbox \ --with-mysql The next problem was that dovecot-auth failed to link: /bin/bash ../../libtool --tag=CC --mode=link gcc -std=gnu99 -O3 -m64 -mcpu=ultrasparc -L/opt/lib/sparcv9 -R/opt/lib/sparcv9 -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -I/opt/include -export-dynamic -O3 -m64 -mcpu=ultrasparc -L/opt/lib/sparcv9 -R/opt/lib/sparcv9 -o dovecot-auth auth.o auth-cache.o auth-client-connection.o auth-master-connection.o auth-master-listener.o auth-module.o auth-request.o auth-request-handler.o auth-stream.o auth-worker-client.o auth-worker-server.o db-ldap.o db-sql.o db-passwd-file.o main.o mech.o mech-anonymous.o mech-plain.o mech-login.o mech-cram-md5.o mech-digest-md5.o mech-ntlm.o mech-gssapi.o mech-rpa.o mech-apop.o passdb.o passdb-blocking.o passdb-bsdauth.o passdb-cache.o passdb-ldap.o passdb-passwd.o passdb-passwd-file.o passdb-pam.o passdb-checkpassword.o passdb-shadow.o passdb-sia.o passdb-vpopmail.o passdb-sql.o userdb.o userdb-blocking.o userdb-ldap.o userdb-passwd.o userdb-passwd-file.o userdb-prefetch.o userdb-static.o userdb-vpopmail.o userdb-sql.o libpassword.a ../lib-settings/libsettings.a ../lib-ntlm/libntlm.a ../lib-sql/libsql.a ../lib/liblib.a -lpam -L -L/opt/lib/mysql -L/opt/lib/sparcv9/mysql -lmysqlclient -lz -lm -export-dynamic -ldl -lsocket -lnsl -lrt mkdir .libs gcc -std=gnu99 -O3 -m64 -mcpu=ultrasparc -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -I/opt/include -O3 -m64 -mcpu=ultrasparc -o dovecot-auth auth.o auth-cache.o auth-client-connection.o auth-master-connection.o auth-master-listener.o auth-module.o auth-request.o auth-request-handler.o auth-stream.o auth-worker-client.o auth-worker-server.o db-ldap.o db-sql.o db-passwd-file.o main.o mech.o mech-anonymous.o mech-plain.o mech-login.o mech-cram-md5.o mech-digest-md5.o mech-ntlm.o mech-gssapi.o mech-rpa.o mech-apop.o passdb.o passdb-blocking.o passdb-bsdauth.o passdb-cache.o passdb-ldap.o passdb-passwd.o passdb-passwd-file.o passdb-pam.o passdb-checkpassword.o passdb-shadow.o passdb-sia.o passdb-vpopmail.o passdb-sql.o userdb.o userdb-blocking.o userdb-ldap.o userdb-passwd.o userdb-passwd-file.o userdb-prefetch.o userdb-static.o userdb-vpopmail.o userdb-sql.o -L/opt/lib/sparcv9 libpassword.a ../lib-settings/libsettings.a ../lib-ntlm/libntlm.a ../lib-sql/libsql.a ../lib/liblib.a -lpam -L/db/src/dovecot/dovecot-1.0.rc17_64bit/src/auth -L/opt/lib/mysql -L/opt/lib/sparcv9/mysql /opt/lib/mysql/libmysqlclient.so -L/opt/lib -lposix4 -lgen -lssl -lcrypto -lz -lm -ldl -lsocket -lnsl -lrt -R/opt/lib/mysql -R/opt/lib/mysql -R/opt/lib/sparcv9 ld: fatal: file /opt/lib/mysql/libmysqlclient.so: wrong ELF class: ELFCLASS32 ld: fatal: File processing errors. No output written to dovecot-auth What is odd about the above is that the input to libtool is completely correct but the resulting gcc command converted -lmysqlclient to an absolute path of /opt/lib/mysql/libmysqlclient.so which is wrong for a 64 bit build - hence the link failure. Why this happened is a mystery to me? If it had been left alone as -lmysqlclient the link would have been successful because the correct 64 bit library would have been found automatically. To get around this problem I added -lmysqlclient to the LDFLAGS input to the configure script which works but isn't very conventional. It would be much cleaner if the --with-mysql had a [=DIR] option and the configure script used the same basic logic that is used in the php configure script for locating the mysql stuff. In addition it is essential that hard paths, especially to shared objects don't get generated during the build since that will block the automatic searching of libraries. -- *Bob Atkins * /President/CEO/ *DigiLink, Inc. <http://www.digilink.net>* Business Inter-net-working */The Cure for the Common ISP!/* Phone: (310) 577-9450 Fax: (310) 577-3360 eMail: bob(a)digilink.net

[Dovecot] Vpopmail auth with vchkpw
by Rick Romero 19 Jan '07

19 Jan '07

Hey Guys, I'm using vpopmail, and was told here that I need to use the vchkpw passwd module to authenticate AND get my lastauth data updated. It works like a charm, but I've come across another minor issue. vchkpw sets the 'connection-type' based on the variable TCPLOCALPORT If that's not set, it defaults to pop. What this does in my environment is cause someone who is denied POP access to also not be able to use IMAP (or webmail) because that variable is not set. Is it possible to have Dovecot set that variable, based on the port the user connected to, prior to calling vchkpw? Or can I Set that in here somehow? passdb checkpassword { args = /usr/local/vpopmail/bin/vchkpw } userdb prefetch { } } Thanks Rick

[Dovecot] Shared folder
by Stefan Klatt 19 Jan '07

19 Jan '07

Hi, first.. i'm new on this list :-) and use dovecot 1.01rc17 under fedora core 5. And i read the list of the last 4 moth and didn't found answers to my questions........ now i work with shared folders and got it running on the following configuration: namespace private { seperator = . prefix = location = maildir:/srv/imapd/user/%u/maildir inbox = yes } namespace public { seperator = . prefix = Public. location = maildir:/imapd/shared/public/maildir:CONTROL=/imapd/user/%u/shared-settings/public/control:INDEX=/imapd/user/%u/shared-settings/public/index hidden = no } location is one line :-) I have different questions to this configuration: if i use "hidden = no" at the private namespace, the complete namespace isn't viewable, if i use "hidden = yes" i see the prefix "private" at the foldernames in my emailclient. Shouldn't be a non existing hidden option the same like "hidden = no"? if use / as the seperator like dokumented at the wiki it doesn't work. with a dot like the seperator at the directories for the emailfolder it works. is there a way to implement ACL for virtuell user in this configuration? The namespace could be a very interesting idea to give other user access to the own mailbox (e.g. for holiday), but for this each user need it's own acl-file which he can change.... And the special folder like Inbox must be viewable from another user. The both last could be realized with an option like "ACL = /imapd/user/%u/rights" to include an file with acldefinition at the namespacedefiniton. Another way could be a option like "ACL_R = user, user, group, group" inside of the namespacedefinition with definition of user and group outside of the namespacedefintion. For me a LDAP request would the best way :-) i realize the complete emailconfiguration with ldap. Stefan

[Dovecot] How change the order POP checks mail.
by Andreas Andersson 19 Jan '07

19 Jan '07

Hello! I have a problem with the POP when I want to use mbox and Maildirs. The old users are now using uw-imap, but in the future should theres old e-mail be in mbox format and the new e-mails in maildirs. I'am using this code and its worked fine in Squirrelmail and IMAP. namespace private { separator = / inbox = yes hidden = no prefix = "mbox/" location = mbox:~/mail:INBOX=/var/mail/%u } namespace private { separator = / prefix = location = maildir:~/Maildir } but not with POP, I can't find any mail. When I only searching for mbox mail, it worked great. I think thats the problem are the pop who first searching for Maildirs and then mailboxes. So how could I get the Dovecot POP server to first check the mailboxes and then the maildirs? Or how should I go around this problem? Thanks! Andreas Andersson

[Dovecot] Shared folder doesn't work!
by Brian Lavender 19 Jan '07

19 Jan '07

I can't seem to get a shared folder working properly. I am authenticating using pam, and the users have a shell account on the system. Problem is, the permissions on the messages moved into the folder don't maintain properly, and other users can't read the share. I have the following in /etc/dovecot/dovecot.conf namespace public { separator = / prefix = Public/ location = maildir:/var/mail/public } # If you create a "namespace public" section, then you need to create # a "namespace private" section namespace private { separator = / prefix = location = maildir:/home/%u/Maildir # There can be only one INBOX, and this setting defines # which namespace has it. inbox = yes } umask = 0007 I am running rc15 from backports on Debian stable. dovecot (1.0.rc15-1~bpo1) sarge-backports; urgency=low * Rebuilt for sarge. * Only changes needed were build dependency on libpq-dev changed back to postgresql-dev, libmysqlclient15-dev changed back to libmysqlclient12-dev, kernel-headers versioned build-dependency removed and debhelper version relaxed to 4. -- Jaldhar H.

I'm using dovecot (rc17) in POP3/IMAP server _and_ proxy mode (pgsql backend). Everything works fine but occasionally I get these messages in the log: dovecot: auth(default): file passdb.c: line 126 (passdb_handle_credentials): assertion failed: (password != NULL) dovecot: auth(default): Raw backtrace: dovecot-auth [0x8062b2b] -> dovecot-auth [0x8062599] -> dovecot-auth [0x805a6ae] -> dovecot-auth [0x805b3b8] -> dovecot-auth [0x8060350] -> dovecot-auth(io_loop_handler_run+0x118) [0x8066458] -> dovecot-auth(io_loop_run+0x28) [0x80658e8] -> dovecot-auth(main+0x78) [0x8057028] -> /lib/libc.so.6(__libc_start_main+0xc6) [0x4007ee36] -> dovecot-auth [0x804f591] dovecot: child 15802 (auth) killed with signal 6 I seems (!) that these messages only appear when someone uses dovecot in in IMAP proxy mode.

[Dovecot] RC15 problems with dovecot-shared and umask distilled
by Glenn Leavell 19 Jan '07

19 Jan '07

I recently posted about problems I've been having with dovecot-shared and umask in RC15 (using Solaris 9). I've now been able to distill what I'm experiencing into these two separate points: 1. dovecot-uidlist and message files never inherit the dovecot-shared group 2. With umask=0007 these files are created with mode 600 instead of 660: dovecot-uidlist, dovecot.index, dovecot.index.log, messages files (cur,tmp,new and the parent directory *are* created 770) (With regard to #1, I originally posted that individual message files were also not inheriting *permissions* from dovecot-shared, but that turned out to be a case of copying a message with maildir_copy_with_hardlinks = yes.) I can duplicate this consistently; can anyone else? Or has this been fixed in RC16/17? Thanks, Glenn

Hello, I have searched but have not found any information on logging imap actions. I want to log when someone uses imap to delete, move, copy, etc. This would greatly help me when someone deletes an email and asks where it went. I get this fairly often from a few users. Any help would be greatly appreciated. Thank you, Michael A. Painter Jr.

[Dovecot] A few rc17 imap crashes
by Chris Wakelin 18 Jan '07

18 Jan '07

We upgraded from 1.0-beta7 to 1.0-rc17 on Tuesday evening and looking at today's logs, just four imap processes out of 90,000+ died. I managed to get core files (the server is running Solaris 8 on Sparc, and Dovecot was compiled with gcc 3.3.2). I hope they're useful! (I should also say that performance between the two versions is roughly similar according to Solaris' process accounting stats, looking at CPU usage and disk blocks accessed.)

[Dovecot] default_mail_env/mail_location syntax changes
by Mike Brown 18 Jan '07

18 Jan '07

Sorry, I tried to find this info on the wiki and in the docs, but couldn't quite figure it out. Dovecot 1.0rc8 introduced this change: "mbox:/var/mail/%u" no longer works as the mail location. You'll have to specify the mail root explicitly, just like the examples always have: "mbox:~/mail:INBOX=/var/mail/%u" If I need a custom INBOX location but the default behavior of using the first of [/ or ~/mail or ~/Mail] having a .imap subdirectory, how do I go about specifying that? That is, on my system, - inbox file: ~/Mailbox - mail storage dir: ~/mail OR ~/Mail (it varies by user) - all files are in mbox format Thanks, Mike

[Dovecot] some Maildir files not honoring dovecot-shared
by Glenn Leavell 18 Jan '07

18 Jan '07

I'm using RC15 on Solaris 9. The wiki indicates that when a dovecot-shared file exists, "Dovecot uses the same permissions and GID when it creates index files, dovecot-uidlist file, new mail files, etc." In my case, Dovecot *is* creating new index files based on dovecot-shared, but dovecot-uidlist and individual message files don't completely match the permissions/group template. Specifically, dovecot-uidlist isn't taking the group from dovecot-uidlist, and individual messages files don't seem to be honoring dovecot-shared at all (group or permissions). Here's an example; every file and directory below in .abusetest-in was created by Dovecot *except* for dovecot-shared (I let Dovecot create cur, new, tmp just to see what it would do, but I know that I can create and fix the group and permissions on these directories myself in a sharing situation): glenn@tony:~/Maildir/.abusetest-in$ ls -lR .: total 34 drwx------ 2 glenn adm 512 Jan 9 09:58 cur/ -rwxrwx--- 1 glenn abuse 0 Jan 9 09:57 dovecot-shared* -rw-rw---- 1 glenn adm 44 Jan 9 09:58 dovecot-uidlist -rw-rw---- 1 glenn abuse 156 Jan 9 09:58 dovecot.index -rw-rw---- 1 glenn abuse 10272 Jan 9 09:58 dovecot.index.cache -rw-rw---- 1 glenn abuse 156 Jan 9 09:58 dovecot.index.log drwx------ 2 glenn adm 512 Jan 9 09:58 new/ drwx------ 2 glenn adm 512 Jan 9 09:58 tmp/ ./cur: total 4 -rw------- 2 glenn adm 1438 Jan 5 09:59 1168354728.P15661Q0M891161.tony:2,S ./new: total 0 ./tmp: total 0 glenn@tony:~/Maildir/.abusetest-in$ I see in the RC16 release notes that there was a fix for the dovecot-keywords file, but it doesn't mention these other files. Is this a bug, or am I misunderstanding how the dovecot-shared file should work?

[Dovecot] assertion failed
by Shaun T. Erickson 18 Jan '07

18 Jan '07

I installed dovecot on a RH9 server this evening, via an RPM from atrpms.net (dovecot-1.0-0_34.rc15.RHL9.at.i386.rpm). The auth portion is working perfectly, as I'm using it to do SMTP AUTH with my postfix 2.3.5 installation. I have configured it to provide imaps. When I connect to it, it rapidly connects, disconnects, connects ... ad infinitum, reporting this, in the logs, each time: Dec 30 16:03:33 max dovecot: imap-login: Login: user=<ste>, method=plain, rip=192.168.32.168, lip=65.206.7.147, TLS Dec 30 16:03:33 max dovecot: IMAP(ste): file istream-raw-mbox.c: line 499 (istream_raw_mbox_get_body_size): assertion failed: (rstream->mail_size != (uoff_t)-1) Dec 30 16:03:33 max dovecot:child 19228 (imap) killed with signal 6 Here is my dovecot.conf file: listen = [*] protocols = imaps disable_plaintext_auth = yes ssl_cert_file = /etc/postfix/max.blackdogsoft.net.crt ssl_key_file = /etc/postfix/max.blackdogsoft.net.key ssl_ca_file = /etc/postfix/cacert.pem default_mail_env = mbox:%h:INBOX=/var/mail/%u mail_read_mmaped = yes verbose_proctitle = yes protocol lda { postmaster_address = postmaster(a)blackdogsoft.net } auth default { mechanisms = plain login passdb pam { } userdb passwd { } socket listen { client { path = /var/spool/postfix/provate/auth mode = 0660 user = postfix group = postfix } } } Suggestions? -- -ste

[Dovecot] Correct usage of NFS mounted Maildirs
by Fran Fabrizio 18 Jan '07

18 Jan '07

Dovecot 1.0RC15 running on Fedora Core 5 kernel 2.6.18-1.2257.fc5smp. A SLES10 server (kernel 2.6.16.21-0.8-smp) has the home directories on an ext3 partition mounted with options (rw,acl,user_xattr,usrquota) which is then exposed as an NFS mount with server side options (rw,no_root_squash,no_acl,async). The home directories include Maildirs to which postfix delivers. The Fedora Core 5 dovecot&postfix machine then mounts this NFS mount with options (rw,hard,intr) Dovecot variables: mmap_disable=yes lock_method=dotlock default_mail_env = maildir:~/Maildir:INDEX=/usr/local/dovecot/indexes/%u (only one dovecot server and wanted to see if local indices helped) I didn't turn off the attribute caching of NFS since I only have one dovecot server, I think the wiki said it was safe to leave on in this case. With this configuration, I am seeing a lot of NFS Stale Filehandle errors, even after moving the index files to a local disk. Here's an excerpt from the log: dovecot: Dec 22 11:23:06 Info: Dovecot v1.0.rc15 starting up dovecot: Dec 22 11:23:22 Info: imap-login: Login: user=<nfsuser1>, method=plain, rip=138.26.64.50, lip=138.26.64.5 dovecot: Dec 22 11:23:24 Info: imap-login: Login: user=<nfsuser1>, method=plain, rip=138.26.64.50, lip=138.26.64.5 dovecot: Dec 22 11:24:48 Info: imap-login: Login: user=<nfsuser1>, method=plain, rip=138.26.64.50, lip=138.26.64.5 dovecot: Dec 22 11:26:43 Error: IMAP(nfsuser1): inotify_add_watch(/nethome/facstaff/nfsuser1/Maildir/.Trash/new) failed: Stale NFS file handle dovecot: Dec 22 11:26:43 Error: IMAP(nfsuser1): inotify_add_watch(/nethome/facstaff/nfsuser1/Maildir/new) failed: Stale NFS file handle To be honest, I'm not 100% sure this is a dovecot problem, because I also see that I am getting stale filehandles when postfix tries to deliver the mail to the Maildir, but I'm curious as to whether this is because of something dovecot did because I have it misconfigured. Does anything about my dovecot config provide any clues as to what I might have done wrong? The NFS mounts are completely stable everywhere except within the Maildirs. From the shell, I can run a loop to call 'ls' 1000 times outside of a Maildir and it works fine. Inside a Maildir, I will get Stale NFS Filehandle errors before long. Does this sound like it could have something to do with my Dovecot config, given that it is happening even after I moved indices to the local disk (still getting stale filehandle errors on files like dovecot-keywords). I performed the following procedure: - shut down dovecot - did a rm-rf Maildir on my test account - unmounted the NFS mount /nethome/facstaff - remounted the NFS mount /nethome/facstaff - set the index files to be local in dovecot.conf and created that directory (/usr/local/dovecot/index/) - sent a few test mails to the user (to recreate the Maildir) - started dovecot - logged in (via Thunderbird) to account through dovecot. - read test message - deleted test message - opened shell to dovecot server - cd'ed into user's Maildir - ran 'ls' a few times. Got Stale Filehandle errors after a few. - back in Thunderbird, tried to read/move/delete other test mails, got the above errors in the log. If it's not a dovecot issue I know it's off-topic, but has anyone else seen similar? I might be imagining this, but I think the problem started when I moved from SLES9 to SLES10 for my fileserver (newer kernel, newer version of NFS, perhaps an incompatibility here?) Thanks, Fran

[Dovecot] Custom mail directory with LDAP
by Maykel Moya 18 Jan '07

18 Jan '07

For certain users, I have their mail boxes under /srv/mpop/<username>/Maildir. For the rest, I have their mail boxes under /srv/vmail/<username>/Maildir. mpop/ users are stored in LDAP, vmail/ users are local users so I discard the idea of set a fixed mail_location. In dovecot-ldap.conf I can't get the picture to set /srv/mpop/<username>/Maildir as mail. I'd tried user_attrs = /srv/mpop/uid/Maildir=mail but watching the logs I saw that a '/srv/mpop/uid/Maildir' is queried to the LDAP Server. Would be nice to have a user_global_mail equivalent to user_global_uid for LDAP user lookups. Regards, maykel

[Dovecot] auth unix sockets
by Uldis Pakuls 18 Jan '07

18 Jan '07

Hi, I'm working on "avelsieve" SqurrelMail plug-in to implement SIEVE "file" back end for dovecot. 1. My be someone my explain me, how to use client auth socket to authenticate against dovecot-auth unix socket. As fas as I understood login must be sent in form "user\0\user\0password" as base64 encoded string. pp code (I'm using socket used by postfix auth): -------------------- <?php $authstr = base64_encode('test@virtual.net\0test@virtual.net\0test'); $fp = fsockopen("unix:///var/spool/postfix/private/auth",0, $errno, $errstr, 30); if (!$fp) { echo "$errstr ($errno)<br />\n"; } else { $out = "$authstr\r\n"; fwrite($fp, $out); while (!feof($fp)) { echo fgets($fp, 128); } fclose($fp); } ?> ----------------------- Dovecot auth complains about syntax It seems 'auth mech' also is required. thus; how to correctly use dovecot client auth socket to authenticate? (some FAQ?, php sample code?) 2. [most important] dovecot LDA uses auth maser sockets to read userdb and get home directory path to deliver mail and locate sieve scripts. I need some home path to locate users sieve script. Wow to obtain it using dovecot auth sockets? Tnx Uldis

[Dovecot] Multiple Mailbox Location
by Giuseppe Giacomini 18 Jan '07

18 Jan '07

Hi, I' m using dovecot v1.0.rc17 on a Centos 4.4 linux box with maildir format. Linux box mounts two LUNs of our Storage Area Network. LUN(a) has been mounted on /home with linux quota enable (small in size , but faster than LUN(b)) LUN(b) has been mounted on /archive with linux quota enable (big in size, but slower than LUN(a) ) I want to create two different private namespaces for our users. The first namespace is used for users' current mail (INBOX,Trash,Sent ....) and is located on faster disk (LUN(a)) The second namespace is used as mail archive. User drags his mail from first namespace to the folders located on the second namespace. This is my namespace definition in dovecot.conf default_mail_env = maildir:/%h/MailDir namespace private { separator = / prefix = inbox = yes hidden = yes } namespace private { separator = / prefix = "#Archive/" location = maildir:/archive/%u/MailDir #hidden = yes } This is the output to NAMESPACE command : 02 namespace * NAMESPACE (("#Archive/" "/")) NIL NIL We have a lot of types of client: Outlook >= 2000, Thunderbird, Eudora 7, Squirrellmail 1.4.8 with different behavior regarding namespace. These are my questions: 1) Is my namespace configuration right? Am I missing something? It is a bit different from that at http://wiki.dovecot.org/Namespaces 2) If I create a folder under the default namespace (i.e. .test under user MailDir) and add the folder name in namespace's subscription , Outlook and Eudora show me the folder and if I open the subscribe menu' they show me the two namespaces with their folders. With Thunderbird I can't see the created folder under default namespace and if I open the subscribe window I can see only the second namespace "#Archive" (That one not hidden). Is it a Thunderbird problem? Thank you

[Dovecot] dovecot-auth file descriptor usage
by Steven F Siirila 17 Jan '07

17 Jan '07

In dovecot-auth (rc15) we experienced problems when the file descriptors reached 256 (due to a Solaris fdopen() call described previously). The issue was that there was one file descriptor being used for every imap-login and pop3-login process (in our environment of SSL-only that means one for every active IMAP and POP connection). Mods were made (and appear in rc16) to close out the descriptor in question after using it during authentication (as I understand it). However, I am still seeing plenty of file descriptors left open in rc16 (one per session). For example, on a Solaris 9 server with 9 IMAP connections open here is an lsof excerpt of dovecot-auth: dovecot-a 26071 root 7u unix 105,136 0t79 3190 /devices/pseudo/tl@0:ticots->/var/opt/dovecot/run/dovecot/login/default (0x3000d084250) dovecot-a 26071 root 8u unix 105,140 0t80 3190 /devices/pseudo/tl@0:ticots->/var/opt/dovecot/run/dovecot/login/default (0x3c9c4227b68) dovecot-a 26071 root 9u unix 105,149 0t79 3190 /devices/pseudo/tl@0:ticots->/var/opt/dovecot/run/dovecot/login/default (0x3cbaa7680b8) dovecot-a 26071 root 10u unix 105,266 0t79 3190 /devices/pseudo/tl@0:ticots->/var/opt/dovecot/run/dovecot/login/default (0x3cbaa765d48) dovecot-a 26071 root 11u unix 105,160 0t79 3190 /devices/pseudo/tl@0:ticots->/var/opt/dovecot/run/dovecot/login/default (0x3cbaa7667e0) dovecot-a 26071 root 12u unix 105,255 0t79 3190 /devices/pseudo/tl@0:ticots->/var/opt/dovecot/run/dovecot/login/default (0x3cbaa769288) dovecot-a 26071 root 13r DOOR 265,0 0t0 50 /var/run (swap) (door to nscd[7752]) dovecot-a 26071 root 14u unix 105,258 0t79 3190 /devices/pseudo/tl@0:ticots->/var/opt/dovecot/run/dovecot/login/default (0x30002dc4008) dovecot-a 26071 root 15u unix 105,282 0t80 3190 /devices/pseudo/tl@0:ticots->/var/opt/dovecot/run/dovecot/login/default (0x30003185738) dovecot-a 26071 root 16u unix 105,141 0t80 3190 /devices/pseudo/tl@0:ticots->/var/opt/dovecot/run/dovecot/login/default (0x30003185ac8) With the modification made, shouldn't these no longer accumulate? -- Steven F.

[Dovecot] Dovecot cannot find passwd-file
by craig carriere 17 Jan '07

17 Jan '07

Posted this once before, but am still having problems. I have dovecot 1.0 rc15 running with postfix 2.3 on a SLES 10 server. With local user and /etc/passwd /pam authentication my local user can retrieve mail. I am now adding a virtual domain and have postifx relaying correctly. I want to have dovecot pull passwd and userdb from two files. When setting passwd-file to /etc/dovecot/passwd the system states that the file does not exist but it does. It does not appear to be a permissions issue; is this a path issue relative to chroot? Would appreciate some input; I have found others with the same issues but have not seen a solution posted.

Hi, I have site w. around 7000 users, most of which have some procmail rules (theres even .procmailrc in /etc/skel with rule to put spam into spam folder). Afaik dovecot's deliver doesnt understand procmail rules, so i'd like to ask if its possible to configure procmail so it saves mail using deliver, without modifying users .procmailrc Thanks for any pointers, Vaclav Hula

[Dovecot] Index corruption causes child process to die
by Juha Saarinen 16 Jan '07

16 Jan '07

My recent migration from Courier-IMAP to Dovecot has been marred by these errors: Oct 24 12:12:40 server dovecot: IMAP(juha): Fixed index file ~user/Maildir/.Geekzone/dovecot.index: first_recent_uid_lowwater 431 -> 430 Oct 24 12:12:40 server dovecot: IMAP(juha): Corrupted index file ~user/Maildir/.Geekzone/dovecot.index: Duplicate header extension keywords Oct 24 12:12:40 server dovecot: child 5786 (imap) killed with signal 11 They happen with Thunderbird 1.5.0.7 and I'm using Dovecot 1.0RC7 from the FreeBSD ports. I think the index corruption may be caused by Tbird's message filtering - I'm asking it to filter certain messages from INBOX to subfolders. When the error occurs, Tbird pops up an error message saying it can't connect to the mail server, but I don't lose any messages it seems. Instead, I get duplicates and even triplicates when I restart Tbird. Any work around for this? -- Juha http://www.geekzone.co.nz/juha

[Dovecot] segfault in RC15
by Cor Bosman 15 Jan '07

15 Jan '07

Hi all, ive seen a few segfaults in RC15. It's hard for me to reproduce but I was able to get a core when it happened with one of our customers. RC15 FreeBSD 4.10 X86 NFS/NetApp It's squirrelmail/webmail client. Can't reproduce it, cant turn on dovecot.rawlog because I dont know in advance which customer will hit this. See it about 5 times per hour, with thousands of logins per hour. Here's the backtrace.. Cor ------ Core was generated by `imap'. Program terminated with signal 11, Segmentation fault.

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

13 Jan '07

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

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

13 Jan '07

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

Re: [Dovecot] Configuring Dovecot for use with Active Directory

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

13 Jan '07

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

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

12 Jan '07

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

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

11 Jan '07

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

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

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

10 Jan '07

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

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

10 Jan '07

People who have had "duplicate header extension" and whatever other random index file corruption problems, please see if this fixes anything: http://dovecot.org/list/dovecot-cvs/2006-December/007315.html The change is also in the latest nightly snapshot (http://dovecot.org/ nightly/dovecot-latest.tar.gz). You could in general treat the latest snapshot as "pretty much the same as the 1.0.rc16 release", so some testing for it would be nice. I've updated autotools that were used to build the snapshot, does anyone have problems with compiling the snapshot? I'm going to build the 1.0rc16 release using the same autotools. rc16 has several changes intended to make Mac OS X's HFS+ happy. This is mostly because currently the only computer I have is a Powerbook. I'll get a new Linux machine in a couple of weeks hopefully. I've still about 50 unread/possibly unanswered mails. I'll try to get to them soon. Here's a list of all the important changes: * IMAP: When trying to fetch an already expunged message, Dovecot used to just disconnect client. Now it instead replies with dummy NIL data. * Priority numbers in plugin names have changed. If you're installing from source, you should delete the existing plugin files before installing the new ones, otherwise you'll get errors. * Maildir: We're using rename() to move files from tmp/ to new/ now. See http://wiki.dovecot.org/MailboxFormat/Maildir -> "Issues with the specification" for reasoning why this is safe. This makes saving mails faster, and also makes Dovecot usable with Mac OS X's HFS+ (after you also set dotlock_use_excl=yes, see below). + Added dotlock_use_excl setting.

[Dovecot] 1.0.rc16 released
by Timo Sirainen 10 Jan '07

10 Jan '07

http://dovecot.org/releases/dovecot-1.0.rc16.tar.gz http://dovecot.org/releases/dovecot-1.0.rc16.tar.gz.sig If you've had problems with getting errors about index files sometimes being corrupted, please try if this release fixes it. If you've reported any bugs that this release hasn't fixed, please report them again so I know they still didn't get fixed and that I didn't forget them. * IMAP: When trying to fetch an already expunged message, Dovecot used to just disconnect client. Now it instead replies with dummy NIL data. * Priority numbers in plugin names have changed. If you're installing from source, you should delete the existing plugin files before installing the new ones, otherwise you'll get errors. * Maildir: We're using rename() to move files from tmp/ to new/ now. See http://wiki.dovecot.org/MailboxFormat/Maildir -> "Issues with the specification" for reasoning why this is safe. This makes saving mails faster, and also makes Dovecot usable with Mac OS X's HFS+ (after you also set dotlock_use_excl=yes, see below). + Added dotlock_use_excl setting. If enabled, dotlocks are created directly using O_EXCL flag, instead of by creating a temporary file which is hardlinked. O_EXCL is faster, but may not work with NFS. + If Dovecot crashes with Linux or Solaris, it'll log a "Raw backtrace". It's worse than gdb's backtrace, but better than nothing. + Added maildir_copy_preserve_filename=yes setting. + Added a lazy-expunge plugin to allow users to unexpunge their mails. + maildir quota: Added ignore setting to maildir quota, which allows ignoring quota in Trash mailbox. + dict quota: If dictionary doesn't yet contain the quota, calculate it by going through all the mails in all the mailboxes. + login_log_format_elements: Added %a=local port and %b=remote port + Added -i and -o options to rawlog to restrict logging only to input or output. - Doing a STATUS command for a selected mailbox (not a recommended IMAP client behavior) caused Dovecot to sync the mailbox silently. This could have lost eg. EXPUNGE events from clients, causing them to use wrong sequence numbers. - deliver was treating boolean settings set to "no" as if they were "yes" (they were supposed to be commented out for "no") - Running "dovecot" with -a or -n option while Dovecot was running deleted all authentication sockets, which caused all the future logins to fail. - maildir: RENAME and DELETE didn't touch control directory if it was different from maildir or index dir. - We treated internal userdb lookup errors as "user unknown" errors.

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

10 Jan '07

Hello everybody! I am a Linux admin trying to move my mail system based on qmail to the software which is more spam-protected: exim4 + dovecot-1.0rc15 + pgsql . I've downloaded and rebuild dovecot from src.rpm (for fc4). During the testing stage I've discovered two troubles: 1) the problem with deliver (...I'm not sure it's a really bug). Here is relevant part of my /var/log/messages : ------- Jan 3 10:40:37 serge deliver(serge(a)test.net): auth input: serge(a)test.net Jan 3 10:40:37 serge deliver(serge(a)test.net): auth input: home=/var/spool/mail/test.net/serge/ Jan 3 10:40:37 serge deliver(serge(a)test.net): auth input: uid=500 Jan 3 10:40:37 serge deliver(serge(a)test.net): auth input: gid=12 Jan 3 10:40:37 serge deliver(serge(a)test.net): setuid(500) failed: Operation not permitted ------- -- my system is fc4 based Linux. uid/gid are according to /etc/dovecot-sql.conf : user_query = SELECT maildir AS home, 500 AS uid, 12 AS gid FROM mailbox WHERE username = '%n@%d' AND active='1' I was trying to chown 500.12 /var/spool/mail -R , chmod u+s ...etc, but it does not helps. Please, help. I don't want another MDA, people adviced me dovecot as good and well tested solution. I have already spent about two work days to configure and test it... 2) Because of mentioned above problem deliver generates a bounce message for exim, and here is a bug with e-mail in the header. It was taken "as is" from the queue of Exim -- have a look at "Return-path:", "envelope-from" and "Sender:" Because of these errors exim can not deliver the message back to sender. It freezes it, ...trying again, ...freezes ... etc... -------------------------------------------------- 1H252L-0004jZ-F3-D This message was created automatically by mail delivery software.

Dovecot generates mail directories according to the user data returned by SQL, and creates index files proper way - everything with given uid.gid = 500.12 ... If you will need some extra piece of information, or my configs or logs -- please feel free to ask for it. Any kind of help: advices, URLs, patches, etc.., are welcome. I badly need to bring up this new system as soon as possible. Thank you in advance. Best regards, Serge www.cis.by

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

10 Jan '07

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

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

10 Jan '07

Hi all, Is there a way to disable the TLS support provided by Dovecot on port 143? I'd like to run SSL on 993, so as far as I can tell I can't use ssl_disable, since the will disable SSL. I'm looking for the equivalent of an ssl_disable_tls setting.

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

09 Jan '07

I was fooling around the /var/run/dovecot directory and I noticed a lot of stale auth-worker.xxxxx sockets, probably left there by unexpected termination of old versions of Dovecot. Just to know who does what, have I to clean up the stale sockets, or a future version of Dovecot will get rid of this unused sockets?

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

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

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

08 Jan '07

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

[Dovecot] rc15 errors
by Nicolas STRANSKY 05 Jan '07

05 Jan '07

Hi, Since I installed rc15 I'm seing the following errors in logs of a server with several hundreds of pop3 and imap users. All the indexes have been erased and recreated after installation. Dec 21 21:06:46 rouge dovecot: pop3-login: inotify_init() failed: Too many open files The maildir mailboxes are on NFS, but the indexes are local. What should be done to correct this error ? These two error have appeared only once: Dec 22 11:02:07 rouge dovecot: IMAP(xxxxxx): file client.c: line 378 (client_handle_input): assertion failed: (!client->disconnected) Dec 22 11:02:07 rouge dovecot: child 31833 (imap) killed with signal 6 Dec 22 12:43:20 rouge dovecot: IMAP(xxxxxx): free(): invalid pointer 0x5bbbe0!

[Dovecot] Failed proxy auth drops connection for IMAP/POP3 proxy in 1.0-RC15
by Bruce Walter 05 Jan '07

05 Jan '07

Hello, I was seeing an odd behavior in a proxy-only configuration of dovecot. When a user entered an incorrect password in either IMAP or POP3, the Dovecot connection would be immediately dropped, sometimes with the auth failure message, sometimes without (a timing issue). I believe I have tracked down the cause to the code commented out in the attached diff. It appears that the proxy handlers are giving the client the go-ahead to attempt authorization again and then dismantling the proxy session. I believe the correct behavior would be to allow LOGOUT or QUIT to end the session and do the tear-down in client_destroy. The commented code all gets executed (with more error checking) in client_destroy, so there shouldn't be any memory leaks that I can see. Please advise if this seems correct or let me know of a different method of fixing. Thunderbird does 'Bad Things (tm)' when the connection is dropped without an authorization failed message... It doesn't re-prompt for the password and the user appears to have correctly authenticated, but the session just sits and no mail can be retrieved. Thanks, - Bruce -- __________________________ Bruce M. Walter Senior Network Manager Rho, Inc 6330 Quadrangle Drive Suite 500 Chapel Hill, NC 27517 T: 919.408.8000 x332 F: 919.408.0999

[Dovecot] Getting "Can't resolve address no: Name or service not known" error when starting Dovecot
by Francesco Piraneo Giuliano 05 Jan '07

05 Jan '07

Hi gentlemen! After running for six month Dovecot 0.99.14 I decided to upgrade to 1.0rc15. Actually Dovecot is running under Slackware Linux 10.2 and I got the package from http://www.linuxpackages.net. Problems? Yes, one! When I try to startup Dovecot program hung: Fatal: Can't resolve address no: Name or service not known I'm not a Dovecot or IMAP guru and I can't imagine what kind of address number (I think is complaining about the machine's IP address) or "name" or "service" that it doesn't know! I googled for the entire afternoon for someone that meet the same problem but I got no interesting clues... Yesterday I installed also iptables and I thought the two things are related so I disabled iptables but... nothing! Here some valuables (I hope!) informations for the good guys that want to help my desperate soul... Thank you again and I hope everybody enjoy the Christmas holidays... Bye!

[Dovecot] deliver as LMTP server?
by Barry Warsaw 05 Jan '07

05 Jan '07

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 One other question; has anybody considered writing a tool that integrates Dovecot's deliver script and an LMTP server? I'm architecting my system so that my internet facing SMTP is Postfix, but the mail folders live on a different machine. Right now, I'm considering putting a highly restricted Postfix on the internal machine, which only accepts forwards from the external machine. IWBNI I could eliminate that extra Postfix process by just letting the external one deliver to an LMTP on the internal machine, which was integrated with Dovecot's deliver. Does anything like that exist? I have a reasonably robust Python LMTP server in the current Mailman trunk. Would it be insane to try to marry that with deliver? ;) - -Barry -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (Darwin) iQCVAwUBRZC95XEjvBPtnXfVAQJgDQP+PxNPZ2453Bb8poBbwtgKAZjwmAJnX4L3 SzipzaoEE8/P8oj/sRwwRO19ViTPmXGZTgQQTF8ipqNL2YAL73QlyeLypzu0ZBBi WyplPkgFlgMeS5rnk9ibyejerO+JdsZt6zKnyKDqdhnhVsgTwvzMsNlu6MaWqtl8 fXPd5Gur6+M= =HGgh -----END PGP SIGNATURE-----

[Dovecot] file descriptor leak?
by Steven F Siirila 04 Jan '07

04 Jan '07

We are having problems with the latest Dovecot 1.0 (RC15) regarding file descriptors > 255 being handed off to fdopen() via crypt() via PAM(?). This is a problem on Solaris 10 due to the fact that the stdio library does not support file descriptors > 255 (in order to remain binary-compatibile with older binaries). Here are the messages we run into if we get too many (~250?) concurrent IMAP/POP sessions: Jan 3 13:03:14 hostname dovecot-auth[5799]: crypt: fdopen(265) failed: Too many open files Jan 3 13:03:14 hostname dovecot-auth[5799]: crypt: fdopen(265) failed: Too many open files Jan 3 13:03:15 hostname dovecot: auth(default): pam(username,10.1.1.1): Child process died Jan 3 13:03:15 hostname dovecot: auth(default): PAM: Child 5799 died with signal 11 Questions: 1) Is there a file descriptor leak, or are there supposed to be this many open pipes in dovecot-auth? (master dovecot has way more than 256 at this point, but apparently does not use stdio.) 2) Has anyone tried compiling Dovecot in 64-bit mode (-xarch=v9)? I have tested the fact that this removes the >255 fd limitation in Solaris 9/10. 3) Has anyone even run into this problem on Solaris? I imagine anyone with more than 250 or so simultaneous IMAP/POP sessions would have had to run into it by now. 4) Anyone have any suggested workarounds (besides compiling in 64-bit mode)? We have upwards of 4500 simultaneous IMAP connections alone on some of our servers (running UW IMAP still), so we obviously need to address this problem before we can fully deploy dovecot in our environment. -- Steven F.

[Dovecot] Too many open files
by Daniel Cox 04 Jan '07

04 Jan '07

I am running Dovecot 1.0rc15 on NetBSD 3.1 with only a few connections. It is built from pkgsrc-2006Q3, with mail/dovecot/ updated to HEAD. kqueue is a default build option - I haven't tried without yet. Mail directories/indexes are on a Linux 2.6.16.29 NFS file system, I have set these options and it performs well: mmap_disable=yes lock_method=fcntl FYI. rc7 had very high CPU use with the same options, which rc15 seems to have fixed :-) I also have this problem with dovecot-nightly-20060225 (1.0beta3) on NetBSD 2.1RC3 using a local ffs file system. This appears in /var/log/maillog: Jan 4 18:44:42 server dovecot: pipe() failed: Too many open files # ps ax|grep dovecot 723 ?? Ss 2:14.15 /usr/pkg/sbin/dovecot 822 ??

I haven't worked out how to make this happen automatically on restart. NOTE: hard never goes above kern.maxfiles which is 1772 (I think the kernel needs to be recompiled to increase further). proc.21494.rlimit.descriptors.soft = 1024 proc.21494.rlimit.descriptors.hard = 1772 # fstat -p 21494 root dovecot 21494 45* pipe 0xcc4e0138 <- 0xcc4e0648 rn Shows an increasing number of pipe files open.

[Dovecot] Custom login_greeting per virtual server?
by Cassidy B. Larson 04 Jan '07

04 Jan '07

Just a quick question, nothing broke. I setup about 5 virtual servers. It's great! I can define which protocols to listen on per server. Just curious why I can specify a unique "login_dir" per server, but not a unqiue login_greeting? Appears dovecot always shows the first login_greeting from the first virtual server. Intended this way? -c

[Dovecot] customizable idle login timeouts?
by Cassidy B. Larson 04 Jan '07

04 Jan '07

We're in the process of migrating from mbox over to maildir. I'm running into a problem with the proxy and timeouts. Appears the idle timeout is set to 60 seconds. This is a bit too low for some of our large mbox files :( Any plans on adding the: #define CLIENT_LOGIN_IDLE_TIMEOUT 60 #define AUTH_REQUEST_TIMEOUT to the .conf file to be tunable on the fly? I ended up just patching the couple of files in question, but it'd be nice.. Cassidy

[Dovecot] Urgent - Setup DoveCot with Plesk
by iSquareOne LLC 03 Jan '07

03 Jan '07

Hey, all, I am trying to setup DoveCot with Plesk. But I could not go through the last step. Setup: MySQL 5.0.22 Qmail Plesk 7.5 DoveCot v1.0 RC15 The problem: I setup sql.conf for user query and password query. I tried different ways, DoveCot always says "Authentication failed". Here are my two SQLs. user_query = SELECT concat('/var/qmail/mailnames/', d.name, '/', m.mail_name) as home, concat('/var/qmail/mailnames/', d.name, '/', m.mail_name) as mail, 101 AS uid, 12 AS gid, 'dirsize:storage=1000000' AS quota FROM accounts a, mail m, domains d WHERE a.id = m.account_id AND d.id=m.dom_id AND m.mail_name='%n' AND d.name='%d' I manully fill in %n=admin and %d=test.com to test it and it worked fine The result is: home,mail,uid,gid,quota "/var/qmail/mailnames/test.com/admin","/var/qmail/mailnames/test.com/admin","101","12","dirsize:storage=1000000" password_query = SELECT concat(m.mail_name, '@',d.name) as user, a.password as password, concat('/var/qmail/mailnames/', d.name, '/', m.mail_name) as userdb_home, concat('maildir:/var/qmail/mailnames/', d.name, '/', m.mail_name) as userdb_mail, 101 as userdb_uid, 12 as userdb_gid FROM accounts a, mail m, domains d WHERE a.id = m.account_id AND d.id=m.dom_id AND m.mail_name='%n' AND d.name='%d' The result is: user,password,userdb_home,userdb_mail,userdb_uid,userdb_gid "admin(a)test.com","password","/var/qmail/mailnames/test.com/admin","maildir:/var/qmail/mailnames/test.com/admin","101","12" I don't know what DoveCot is expecting to get from the SQL result. Please let me know if I missed anything. Thank you very much! __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

[Dovecot] Error reading configuration file
by Justin Pearce 03 Jan '07

03 Jan '07

Good day, I seem to be having an issue using dovecot 1.0 rc15. I compiled the source with the following configure command: CPPFLAGS="-I/usr/local/include/mysql" LDFLAGS="-L/usr/local/lib/mysql" -lmysqlclient" ./configure -with-mysql -with-sql-drivers=mysql Did make and make install and set the dovecot-example.conf to dovecot.conf and tried running the program and got the following error: Error: Error in configuration file on line 50: expecting '=' Line 50 of the default config is a comment, which struck me as odd. So, I uninstalled and tried building with no options. I did a make uninstall, removed the /usr/local/lib/dovecot directory did make and make install and tried the program. This time it didn't crash about the config file, but the mail.err log notes that the child processes died on an error 89, apparently unable to figure our what pam was. I'm wondering why the thing seems to work if I do not build for mysql but if I want mysql, it breaks in the manner it does? Is it a bug, or am I doing it wrong (which is a real possibility). Any help soon would be appreciated, as my boss keeps asking 'So, when is that mail server going to be done?'. :) Justin Pearce Information Technology/Programming Price Video Productions JustinP(a)PriceVideo.com 361-572-3810 800-733-3810 Fax: 361-572-3894 www.PriceVideo.com

[Dovecot] DvCot/PstFix Virtual Domains Virtual Users PAM Authentication - How pls
by Kyle 03 Jan '07

03 Jan '07

Hi Folks, I'm hoping some one can set me straight here please. Postfix 2.1.5 Dovecot 0.99.11-2 I have Postfix set up on a new box with Virtual Domains and Virtual Users using MailDir format with their mail homes in /var/spool/mail/<domain>/<user> I want Dovecot to login using PAM Authentication. The idea is to host multiple domains which each have multiple aliases which resolve to one email account for their respective domain but using a user name which actually _is_ a system user. So I might have; jo(a)abc.com joe(a)abc.com joey(a)abc.com pete(a)abc.com peter(a)abc.com jo(a)xyz.com joe(a)xyz.com joey(a)xyz.com pete(a)xyz.com peter(a)xyz.com where 'joe' and 'peter' are both system users each with mail homes of; /var/spool/mail/abc.com/joe /var/spool/mail/abc.com/peter /var/spool/mail/xyz.com/joe /var/spool/mail/xyz.com/peter In my dovecot.conf, I have; auth_userdb = static uid=89 gid=89 home=/var/spool/mail/%d/%u auth_passdb = pam If I login with just 'joe', I get; Fatal: chdir(/var/spool/mail//joe) failed with uid 89: Not a directory Fair enough, that sounds logical to me. But if I then login with 'joe(a)abc.com', I get; PAM: pam_authenticate(joe(a)abc.com) failed: Authentication failure So it appears Dovecot is checking PAM for 'joe(a)abc.com' rather than just 'joe'. How can I make it check for just 'joe' please? -- ------------------------------------------------------------------------ Kind Regards Kyle

[Dovecot] configured mechanisms don't work
by Eggert Ehmke 03 Jan '07

03 Jan '07

Hi, I am new to this list and to dovecot. Forgive me if I ask long discussed items. I managed to install postfix and dovecot 1.0.rc15 on a Debian Sarge server out of the backports. It works so far, I can send emails via smtp to postfix, they are stored in the virtual mailboxes of some users, and I can get them via IMAP from dovecot. However, in dovecot.conf I configured mechanisms = plain login digest-md5 cram-md5 when I connect to the server via telnet 143, I get this: 2 CAPABILITY * CAPABILITY IMAP4rev1 SASL-IR SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN NAMESPACE LOGIN-REFERRALS STARTTLS LOGINDISABLED 2 OK Capability completed. So I can't authenticate using cram-md5. What may I be missing? Regards & happy new year! Eggert

[Dovecot] determining connection type/port in logs
by Glenn Leavell 03 Jan '07

03 Jan '07

Is there a way to configure logging to indicate what connection type was used to authenticate? I'd like to be able to tell from the logs whether the user used STARTTLS on port 143 or an SSL-wrapped connection on port 993. Using RC15 with auth_verbose=yes gives us the following log entries during login and logout (lines wrapped for convenience): # login port 143 with STARTTLS: Jan 3 14:17:24 tony dovecot: [ID 107833 local5.info] imap-login: Login: user=<glenn>, method=plain, rip=10.0.0.2, lip=192.168.1.2, TLS Jan 3 14:17:41 tony dovecot: [ID 107833 local5.info] IMAP(glenn): Disconnected: Logged out # login port 993/SSL Jan 3 14:19:11 tony dovecot: [ID 107833 local5.info] imap-login: Login: user=<glenn>, method=plain, rip=10.0.0.2, lip=192.168.1.2, TLS Jan 3 14:19:20 tony dovecot: [ID 107833 local5.info] IMAP(glenn): Disconnected: Logged out Turning on auth_debug=yes added some additional info, but I still wasn't able to tell what port or connection type was used.

[Dovecot] Ampersand in Folder names causing folders to disappear?
by Mark Adams 03 Jan '07

Hi All, Dovecot 1.0.rc7 Not sure if this is a problem with Outlook, or with Dovecot, or to do with encoding in Linux. Whenever a user enters an ampersand into an IMAP folder name, it dissapears from outlook. These folders appear on the ext3 filesystem as &- for example drwx------ 5 mailusers mailusers 4096 2006-10-10 17:54 .INBOX.Networks.London Networks.NDCs.WH&-P joint working Any pointers or previous experience anyone has of this would be very gratefully received.

[Dovecot] "Not connected to database" MySQL errors
by Cassidy B. Larson 03 Jan '07

03 Jan '07

I've been in the process of moving my pop3 proxy over to the dovecot proxy. I have a ton of users using pop3 still, and am seeing these errors popup within a minute or so of the connection to the database: Password query failed: Not connected to database Eventually the auth-worker will reconnect to the database and things will go on normal for another minute or two, then the same issue occurs. I'm runing MySQL 5.0.22 on FreeBSD 6.1. I upgraded to 5.0.27, however I started getting the: "Password query failed: Commands out of sync; you can't run this command now" error instead. So I downgraded until I could figure out this issue first. I've tried connecting to localhost, /tmp/mysql.sock, and a remote server and all exhibit the same problem. The MySQL idle timeouts shouldnt come into play because I'm constantly having users check their accounts. Any insights will be useful, Thanks!

[Dovecot] Dovecot and Mail.app
by Barry Warsaw 03 Jan '07

03 Jan '07

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I'm trying to convert a courier-imap installation over to using Dovecot, but I'm having some problems with Mail.app on OS X. FTR, we use both Mail.app and Thunderbird. Note that in the Mail.app preferences, I have a blank IMAP Path Prefix. I'm using Dovecot 1.0_rc15 on Gentoo, and Mail.app from OS X 10.4.8, Thunderbird 1.5.0.9. With the old courier setup, in Mail.app I would see a top level Inbox folder, with an inbox icon'd folder underneath that representing the IMAP account. That IMAP account subfolder would be the inbox of that account. Under that, I'd see all the subfolders for that account. Something like: Inbox Account1 Folder1 Folder2 ... Account2 FolderA Outbox Drafts Sent Junk SmartFolder1 SmartFolder2 Note that a straight copy from the courier Maildir leaves me with directories like ~/Maildir/.Folder1 and ~/Maildir/.Folder2 -- IOW, they do not have .INBOX. prefix. I tried adding a "namespace private" section, with separator, prefix, and inbox values as specified in the docs. This gives me the same layout in the Mail.app u/i as with Courier, but there's a big problem: none of the folders under Account1 have any contents. The folders are there, and in the right location, but they have zero messages (even though they certainly have messages in the filesystem). Nothing in the Dovecot log file indicates any problem. But if I hover over say Folder1 in the Mail.app u/i, I see a popup message like: Mail was unable to open this mailbox on the server "imap.example.com". The server error encountered was: Unknown namespace Moving over to Thunderbird though, I see exactly what I want to see. Top level expandable is the account, with Inbox under that, which expands to all my folders. Of course Thunderbird supports subscriptions, which Mail.app does not, so I only see the folders I've subscribed to. Clearly, there's some weird interaction between Mail.app and Dovecot. Next, I tried removing the 'prefix' value from the "namespace private" section, and restarted Dovecot. Now the Mail.app u/i is different, but all the folders have their contents back! The u/i now shows: Inbox Account1 Account2 FolderA Outbox Drafts Sent Junk SmartFolder1 SmartFolder2 Account1 Folder1 Folder2 IOW, all of account1's folders live under a separate expandable section below the top level Inbox expandable (that section has a little world icon instead of the little inbox icon). Account1's inbox lives in a different section from its folders, but it has no subfolders. Looking back at Thunderbird, I notice that all the subscribed folders are now at the same level as the Inbox, just under the account name. I.e. Account1 Inbox Trash Folder1 Folder2 ... I suppose I can live with the Mail.app behavior sans the prefix setting in the namespace section, but it's not ideal. I'd really like to know why Mail.app has a problem with this! Why are the folders there but the contents empty? Is there any way to increase the logging that Dovecot does to understand what the Mail.app client is sending and why Dovecot is sending back that error? Any help would be greatly appreciated! - -Barry P.S. I wasn't able to use courier2dovecot.sh from the wiki (I think others had problems with running it on Linux as well, probably due to the different rename(1) syntax). The courier2dovecot.py file was no longer available, so I wrote my own. I can make that available to folks if there's any interest. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (Darwin) iQCVAwUBRZC8sXEjvBPtnXfVAQK90gQAjFhEH+vIPh7pnY4MuOTU8ChWfJ57ppIQ g0HvHidiD5nOfd8pfpsfacdD1nC40cRlpnJkR6vcahvqQsLzSUzUMwVlUqP2IDSE jGvZGpGSBpjTHV/ktWbyJhPo9+ehVxiq+qEfbDgfw9iqBtulOXe4M25iUKO8tsuA n2bCHHoUXuk= =hxad -----END PGP SIGNATURE-----

We are running Dovecot 1.0-rc15 on Solaris 10 and are starting to ramp up our user count and ran into a file descriptor limit: Jan 1 19:38:54 <hostname> dovecot: IMAP(username): Newly created index file is corrupted: /home/username/.imap/foldername/dovecot.index.tmp Jan 1 19:38:54 <hostname> dovecot: IMAP(username): file mail-index.c: line 1806 (mail_index_move_to_memory): assertion failed: (index->fd == -1) Jan 1 19:38:54 <hostname> dovecot: pipe() failed: Too many open files Jan 1 19:38:54 <hostname> dovecot: Temporary failure in creating login processes, slowing down for now We got around this by calling "ulimit -n 512" and restarting Dovecot. This got us further (upwards of 300 concurrent users), but we are now running into what appears to be a full listen queue (connections are not rejected, but rather slow in being established). What I would like to know is if anyone else out there runs with large numbers of concurrent IMAP sessions via Dovecot and has run into problems. If so, did you have to up your fd limit w/ulimit?

[Dovecot] Dovecot SASL vs. Micro$oft Outlook and Outlook Express
by Tom Kovar 02 Jan '07

02 Jan '07

Hi, I have just started using Dovecot (1.0.10) SASL behind my Postfix (2.3.3). Everything works fine, as long as I send the SMTP AUTH command manually. When using M$ Outlook (2000 and 2003) and Outlook Express 6, authentification always fails. Turning on the Dovecot auth debug on reveals the reason: Dovecot SASL expects, in accordance with the standards, the following format of the SMTP AUTH command (using the PLAIN auth mechanism): AUTH PLAIN base64_encode("username\0username\0password") whereas the M$ clients send as the second argument only base64_encode("username\0password"), which naturally leads to authentification failure. Postfix apparently does not play any role in this game, as it simply passes the received command arguments to dovecot. Before I start hacking the source myself, I just wanted to ask if somebody has a patch for this M$ shortcoming - as the damned M$ clients are very much spread, I would assume this should be the case... Thanx, --- Tom

[Dovecot] Correct naming scheme for dovecot / squirrelmail subfolders?
by M. Fioretti 28 Dec '06

28 Dec '06

Hello, I am running dovecot 1.0-0_34.rc15 and squirrelmail 1.4.8-2 on a Centos 4 server. Right now all messages are delivered to maildir /var/mail/vhosts/virtual_mail_root/, which has its cur, tmp, new subdirectories. I need to (re) configure postfix, dovecot and squirrelmail so that email is filtered and dovecot serves different boxes to squirrelmail, that is when I log in in squirrelmail I see: Inbox work (5) friends (6) lists (35) Sent Trash Spam that is every subfolder listed under Inbox with the number of unread messages. Now, I do know how to filter incoming email in different folders with postfix. The part still missing, in spite of several online searches, is the correct _naming_ and nesting of all the new mailboxes. In other words, if now everything goes into /var/mail/vhosts/virtual_mail_root/ : 1) what is the currect _name_ to give to the future "work" inbox ?? /var/mail/vhosts/virtual_mail_root/work/ /var/mail/vhosts/virtual_mail_root/INBOX.work/ what else? 2) which parameters must be changed and how in dovecot and/or squirrelmail (or any IMAP client in my home PC) so that folders are recognized and displayed as I wish?

[Dovecot] Dovecot + Outlook express + permission denied
by Nagy László 28 Dec '06

Hello, I have an account (called awesome) that does not have access to some public shared folders. I can use this account from Mozilla Thunderbird, but I cannot use it from Outlook. I opened /var/log/maillog. When I try to list all folders, I get this in the log: Dec 28 09:57:38 designaproduct dovecot: IMAP(awesome): opendir(/var/mail/public) failed: Permission denied However, outlook displays three folders: Inbox, Public and Trash. It says "One or more problems occured downloading your list of folder from your account." That is fine, except that not all folders are listed.

Why outlook wants to open these folders? I only clicked on "Inbox", it should only open "Inbox", am I right? Outlook says "Could not select 'Inbox' on the IMAP server. You might try refreshing your folders list to synchronize with the IMAP server." But this is a lie. It tried to open many other folders, not just "INBOX". I think that my dovecot configuration is okay. I have different public and private folders. Some users can access all of them, others cannot. Using different groups of users, I can distribute permissions without problems. But I cannot make dovecot "hide" shared folders. Nor can I force all of my users to use Thunderbird. So how can I make outlook working? Thanks, Laszlo

[Dovecot] imap failed asssert in imap-bodystructure.c
by Matt Ronge 26 Dec '06

26 Dec '06

I'm running Dovecot on a Debian system which recently has been failing on an assert(). I have a spam mailbox that if I try and open (from any client), the imap process dies and this is written to the error logs: Dec 21 18:57:11 theronge imap(mronge): file imap-bodystructure.c: line 278 (part_parse_headers): assertion failed: (part->physical_pos >= input->v_offset - start_offset) Dec 21 18:57:11 theronge dovecot: child 28911 (imap) killed with signal 6 I had this same issue with my Inbox a few weeks ago, so I moved all the e-mail out and moved each piece back in one by one, in order to determine if a piece of mail was causing the issue. As soon as all my mail was moved back in, the issue went away and I was able to load my Inbox as usual. I still have the same issue with my spam mailbox, is there anything particular I can do to help debug this issue? In the past I've rm'ed all the mail in my spam mailbox and that fixes it. One thing that may be related is that I only noticed this issue after I had setup Spambayes, which does it's work via procmail. The mailboxes that I've had the issue with, all had headers that contain a Spambayes header, usually like so: X-Spam-Score: 26 X-Spam-Score: 0.6 (/) Sender: mailman-bounces(a)acm.uiuc.edu Errors-To: mailman-bounces(a)acm.uiuc.edu X-Spam-Score: 0.1 (/) X-Authenticated-Sender: X-Spam-Details: rule=cautious-plus_notspam policy=cautious-plus score=26 mlx=26 adultscore=0 adjust=0 reason=mlx engine=3.1.0-0611300000 definitions=main-0612060023 X-Spam-OrigSender: mailman-bounces(a)acm.uiuc.edu X-Spam-Bar: *** X-Spambayes-Classification: spam; 1.00 X-Spambayes-Trained: spam I'm not sure if it's related, but it's a shock in the dark on my part. Any suggested steps that might help isolate this bug? -- Matt Ronge

[Dovecot] Intermittent "cannot update mailbox" problems w/ postfix & dovecot
by John Reddy 26 Dec '06

26 Dec '06

I hate asking questions on mailing lists, but I've exhausted my googling and FAQ trawling skills. If I've missed the pertinent doc, please tell me where to RTFM. Environment: I'm running postfix 2.3.2 on a Solaris 10 server. Mail goes into standard mbox format in /var/mail. Users can access their mail via shell (pine, mutt), POP3 or IMAP, and the pop3/imap server is dovecot-1.0.rc15. Problem: For a few users, mail occasionally fails to deliver. The mail is accepted by smtpd, passes cleanup and qmgr without incident. When it gets to local delivery, though, local complains that "cannot open file: Permission denied". A sample log entry (slightly sanitized): Dec 7 09:42:05 solaris-host local[18332]: [ID 197553 mail.info] D35C3445C: to=<bubba(a)solaris-host.sample.com>, relay=local, delay=0.17, delays=0.09/0/0/0.08, dsn=5.2.0, status=bounced (cannot update mailbox /var/mail/bubba for user bubba. cannot open file: Permission denied) Dec 7 10:52:26 solaris-host local[20775]: [ID 197553 mail.info] 670C9445D: to=<jack(a)solaris-host.sample.com>, relay=local, delay=15, delays=8.9/0/0/6.5, dsn=5.2.0, status=bounced (cannot update mailbox /var/mail/jack for user jack. cannot open file: Permission denied) Does anyone have any advice on how I might get better details about why postfix is having trouble accessing the file? Has anyone run into this before? My initial suspicion is a lock file from the users' POP3 connections... Thanks in advance for any help. -John

Is this as easy as moving everything in ~/mail to /var/mail/ and editing /etc/dovecot/dovecot.conf to read mail_location=mbox:~/mail:INBOX=/var/mail/%u ? Also, is the syntax mail_location=mbox:/var/mail/%u-folders:INBOX=/var/mail/%u correct? Regards, -- Whatever it is, I fear Greeks even when they bring gifts. -- Publius Vergilius Maro (Virgil)

[Dovecot] vpopmail problem
by Toni Panadès 26 Dec '06

Hi! Sorry for my english... I recently know about dovecot and I try to use it on my server. Previously I used qmail+vpopmail+courier and now I want to use postfix+dovecot and, to mantain all my mailboxes structure, I try to use dovecot with vpopmail. During configuration the script detects my vpopmail installation and configuration and after I get this status: Install prefix ...................... : /usr/local File offsets ........................ : 64bit I/O loop method ..................... : poll File change notification method ..... : dnotify Building with SSL support ........... : yes (OpenSSL) Building with IPv6 support .......... : yes Building with pop3 server ........... : yes Building with mail delivery agent .. : yes Building with GSSAPI support ........ : no Building with user database modules . : static prefetch passwd passwd-file checkpassword vpopmail (modules) Building with password lookup modules : passwd passwd-file shadow checkpassword vpopmail (modules) And after some testing I start the daemon with this config: protocols = imap imaps pop3 pop3s auth default { mechanisms = plain passdb vpopmail {} userdb vpopmail {} user = vpopmail } I connect to localhost via pop3 and when I try to auth some user I get this: Dec 26 01:27:45 anet dovecot: auth(default): client in: AUTH 1 PLAIN service=IMAP secured lip=127.0.0.1 rip=127.0.0.1 resp=AHNyb2RvbkBncmFjaWFuZXQub3JnAHR3aXN0 Dec 26 01:27:45 anet dovecot: auth(default): vpopmail(srodon(a)anet.org,127.0.0.1): unknown user Dec 26 01:27:46 anet dovecot: auth(default): client out: FAIL 1 user=srodon(a)anet.org Dec 26 01:27:46 anet dovecot: imap-login: Aborted login: user=<srodon(a)anet.org>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured I tried other auth methods but I get an "Unsupported authentication mechanism" error.

[Dovecot] Sizing login_process_size and login_processes_count?
by Francisco Reyes 25 Dec '06

25 Dec '06

Any suggestions on sizing login_process_size and login_processes_count for a server expected to be doing 100 to 200 simultaneous connections? Is there a way to separate login_processes_count between imap and pop? I would like to have at least 50 imap processes ready, but we rarely have any more than 5 to 10 pop connections. Would be a shame to have 40+ pop login processes doing nothing most of the time. For now did login_process_size = 96, but with an average of 100 to 200 and some rare ocassion of 300+ connections I am wondering what is a reasonable number for login_process_size.

[Dovecot] LDA + sieve +Maildir?
by Francisco Reyes 25 Dec '06

25 Dec '06

I have a working Dovecot + LDA + Maildir setup and am looking to implement sieve with it. The examples that I have seen seem to be for mbox. Does sieve work with maildir? Looking to move mails marked as spam to a spam folder. Also we have a feature we offer to send spam to a different account in the domain. Could this also be done with sieve?

I suspected as much, though I had hoped that there was an easy applicable solution. Sadly my MS-using clients are reluctant at best to change their applications, flawed as they may be, so I guess they'll have to live with things as they are for now. MS really should fix their apps, but that's a topic for a discussion of it's own. I use a mysql-backend, and suspect I could change the login-call to match whatever Outlook or Entourage choose to send, but that would be difficult to make consistent enough to be truly workable, I think... Thanks for your time /Lars

[Dovecot] NTLM authentication woes
by Lars Skovgaard 24 Dec '06

24 Dec '06

Hi all, I have set up dovecot to use a number of different authentication- mechanisms, which are all working as expected from well-behaved clients. However, MS Outlook on Windows and MS Entourage X on Mac OS X refuse to connect using NTLM. Outlook Express on Windows seems to be working fine, and NTLM authentication works from within OS X Mail.app as well. Turning on auth_debug and auth_verbose has led me to discover that MS Outlook uses the users full name as login, instead of whatever is entered in the account-information - if the user "John Doe" has the login "jd(a)domain.com", Outlook sends "John Doe" instead. This of course fails. Strangely enough, if I turn off "Use Secure Authentication" from within Outlook, the login-name from the account- information is used as it should be. From MS Entourage, the problem is similar but not identical. Here, the login is sent as "jd(a)domain.com/jd". I have worked around the problem for now by instructing my clients to use SSL-connections and disabling "Secure Authentication", but would like for everyone to be able to log on without using SSL (due to the returning questions regarding my self-signed certificate). Can anyone shed some light on why the MS apps refuse to behave? Thanks in advance! /Lars PS: I wish you all a merry christmas and a happy new year! :o)

[Dovecot] Postfix + Doveot SASL
by Marco Nenciarini 23 Dec '06

23 Dec '06

Hi, i'm trying to configure my postfix to use dovecot SASL instead of saslauthd with rimap to authenticate my users. I've modified my postfix/dovecot configuration as is described on http://wiki.dovecot.org/PostfixAndDovecotSASL but when an user try to login it fails with the following log (debug_auth = on): Dec 12 15:07:53 lorien dovecot: auth(default): client in: AUTH^I1^IPLAIN^Iservice=smtp^Iresp=<hidden> Dec 12 15:07:53 lorien dovecot: auth(default): passdb(mnencia(a)prato.linux.it,master): Attempted master login with no master passdbs Dec 12 15:07:55 lorien dovecot: auth(default): client out: FAIL^I1^Iuser=mnencia(a)prato.linux.it The question is? Why i need a master login to use SASL? How to make my postfix SASL using usual userdb?
