[Dovecot] Maildir and Windows NFS server
by Julian Jimenez 13 Jul '07

13 Jul '07

Hi, I want to migrate form Courier to Dovecot. The problem is that our NFS server is a Windows server. We use Debian stable (Etch) and maildir. With Courier, we need to compile from the source, changing the parameter MDIRSEP from ":" to ";", because Windows cannot handle files with this character in their name. Anyone knows the name of the parameter in Dovecot that I need to change to do the same? Thanks in advance. Julián

[Dovecot] Dovecot login failing
by Richard Ellis 13 Jul '07

13 Jul '07

Fedora 7 Dovecot version 1.0.1 Hi All, I've been using a combination of getmail/Dovecot/Squirrelmail for a while now and its all been fine. However, last week when trying to demonstrate how to use Squirrelmail to my wife, her login failed. I then tried mine, which I had used many times before and it also fails. Looking in the logs, Dovecot appears to be trying to add a domain name against the login, instead of just checking that user against the UNIX logins of my machine. I thought at first this was because when I'm away from home, I use a no-ip address to access my mailserver, but it also fails when I'm in the house, or even on the server console. dovecot: Jul 12 12:04:56 Info: imap-login: Aborted login: user=< rick(a)servehttp.com>, method=PLAIN, rip=::ffff:127.0.0.1, lip=::ffff: 127.0.0.1, secured dovecot: Jul 12 12:10:00 Info: pop3-login: Login: user=<rick>, method=PLAIN, rip=::ffff:127.0.0.1, lip=::ffff:127.0.0.1, secured Anybody any idea how to rectify this? I can't see an option in the /etc/dovecot.conf file to stop it and using auth_default_realm = doesn't seem to make any difference. If I telnet into dovecot using my local username and password, it works fine. Any advice would be most welcome before I break it fiddling. Thanks Rik -- The Truth is out there, does anyone have the URL?

[Dovecot] v1.0.2 release candidate
by Timo Sirainen 13 Jul '07

13 Jul '07

http://dovecot.org/tmp/dovecot-1.0.2-rc.tar.gz Unless someone finds something broken, I'll release v1.0.2 in a few days. The most important changes since v1.0.1: * dbox isn't built anymore by default. It will be redesigned so it shouldn't be used. + Maildir: Support reading dovecot-uidlist (v3) files created by Dovecot v1.1. - Maildir: "UIDVALIDITY changed" errors could happen with newly created mailboxes - If "INBOX." namespace was used, LIST returned it with \HasNoChildren which caused some clients not to show any other mailboxes. - Maildir++ quota: If multiple processes were updating maildirsize at the same time, we failed with "Unknown error". - IMAP: IDLE didn't actually disconnect client after 30 minutes of inactivity. - LDAP passdb/userdb was leaking memory - deliver: %variables in plugin {} weren't expanded

[Dovecot] Monitoring Recomendations
by Dehnert James Sr 13 Jul '07

13 Jul '07

I have a client that I have installed Dovecot 1.0.1 for is having some performance issues. Especially when using IMAP from various Outlook clients. I have TLS installed and all the IMAP connections are secured. I'm wondering is anyone has any recommendations for monitoring dovecot performance. I'd like to try and nail down where the real performance issues are. I suspect outlook, but I want to eliminate Dovecot as the cause of any problems, or, if I have a problem with Dovecot, I want to identify any issues I can and fix them.

[Dovecot] Quota Messages
by Hermann wacker 13 Jul '07

13 Jul '07

Hi @all, First: I'm sorry when my english isn't understandable, please just ask if I messed things up. I switched from Cyrus to Dovecot (Cyrus was on Debian Sarge, Dovecot is now on a Etch) and I'm quite happy with it. There is just one thing that I'm missing in Dovecot. in Cyrus when users reached 90% of their Quota, a message popped up in their Mailclients, telling them to clean up their Mailboxes. Dovecot delivers the quotausage to the Client (I can see in my Thunderbird a small Statusbar), but when you don't look carefully, you will mostly miss the point where you can delete the messages without having a fight with the quotalimit (because mails in trash using the quota). At the moment I'm using "quota = fs" so there is no good way to keep the trash out of the quotathing and that's not the point of my question. The question is: Is there a way where Dovecot (or Postfix) inform the user that his quota is reaching its limit? Or maybe the postmaster, thats not important. The important thing is a way where my mailsystem tells somebody that quotas are reaching their limits. Greetings from Germany Hermann Wacker Dovecot Version: 1.0.rc15 Postfix Version: 2.3.8-2+b1 quotaconf: # /etc/dovecot/dovecot.conf IEffective uid=65534, gid=65534 ILoading modules from directory: /usr/lib/dovecot/modules/imap IModule loaded: /usr/lib/dovecot/modules/imap/lib01_quota_plugin.so IModule loaded: /usr/lib/dovecot/modules/imap/lib02_imap_quota_plugin.so log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login mail_extra_groups: mail mail_location: maildir:%h/mails mail_debug: yes mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv auth default: passdb: driver: shadow userdb: driver: passwd

[Dovecot] Patches to log imap bandwidth?

Anyone patch dovecot to syslog bytes transfered during a session or anything of that sort? I'm trying to track down imap bandwidth spikes, and unfortunately the uid (according to ipfw) for the imap port spikes is 0.

[Dovecot] v1.1 status and benchmarks
by Timo Sirainen 13 Jul '07

13 Jul '07

v1.1 plans have changed a bit. I'll release v1.1.alpha1 soon and hope to have a stable v1.1 in a month or two. The rest of the features that didn't make it into v1.1 will go to v1.2. I'll write more about this when v1.1 alpha is released. I also did a bit of benchmarking. v1.1's performance improvements are looking pretty great, it seems to be twice as fast as v1.0. v1.0: Maildir, dovecot-1.0 hg + inotify dotlock wait patch, mmap_disable=yes v1.1: Maildir, dovecot hg, mmap_disable=no cydir: Cydir, dovecot hg, mmap_disable=no 1 client -------- ./imaptest logout=0 seed=1 secs=10 clients=1 Logi List Stat Sele Fetc Fet2 Stor Dele Expu Appe 100% 50% 50% 100% 100% 100% 50% 100% 100% 100% 30% 5% v1.0: 1 1221 1179 1 2420 3458 323 1934 2419 2552 v1.1: 1 2606 2597 1 5221 7352 688 4181 5221 5489 cydir: 1 4495 4534 1 8960 12786 1216 7224 8959 9434 10 clients ---------- ./imaptest logout=0 seed=1 secs=10 clients=10 Logi List Stat Sele Fetc Fet2 Stor Dele Expu Appe 100% 50% 50% 100% 100% 100% 50% 100% 100% 100% 30% 5% v1.0: 10 2058 2102 10 4157 6019 1426 3348 4157 4391 v1.1: 10 5029 5072 10 10064 14352 3176 8092 10064 10624 cydir: 10 6332 6393 10 12664 17965 3958 10154 12663 13336

[Dovecot] NFS cache flush tester
by Timo Sirainen 13 Jul '07

13 Jul '07

http://dovecot.org/tools/nfstest.c I wrote a test utility that tests different ways to flush NFS attribute cache and data cache. Please test in your NFS setup and show me the results, so I can make Dovecot v1.1 works well with NFS. Run the test several times (3 should be enough) to make sure the output stays the same, because the attribute cache flushes might incorrectly say "OK". And of course attribute cache must not be disabled for this test to work. If you have other ideas how to flush either cache please tell me and I'll update the test utility. I'd like to have a way to flush the cache without having the NFS client send anything to server. Unfortunately all of the below ways do that. Results for Linux v2.6.15 and v2.6.18: Info: Testing attribute cache.. Info: Attr cache flush fchown(-1, -1): failed Info: Attr cache flush fchown(uid, gid): OK Info: Attr cache flush fchmod(mode): OK Info: Attr cache flush chown(-1, -1): failed Info: Attr cache flush chown(uid, gid): OK Info: Attr cache flush chmod(mode): OK Info: Testing data cache..

[Dovecot] Problem with Dovecot SASL in Postfix
by Chris McMacken 12 Jul '07

12 Jul '07

I'm trying to configure my postfix server to use Dovecot as an SASL server and running into some problems. My server supports a couple of domain, I have multiple user/password files for multiple domains to make the files a little easier to manage. Not sure if this question should belong in the dovecot mailing list or the postfix one, but here goes anyway. I have everything configured to use CRAM-MD5 authentication, including my mail client. Here the auth section of my dovecot conf. auth default { mechanisms = plain cram-md5 passdb passwd-file { # Path for passwd-file args = /usr/local/etc/dovecot/%d/passwd } userdb passwd-file { # Path for passwd-file args = /usr/local/etc/dovecot/%d/passwd } user = root # It's possible to export the authentication interface to other programs: socket listen { client { # The client socket is generally safe to export to everyone. Typical use # is to export it to your SMTP server so it can do SMTP AUTH lookups # using it. path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } } heres a sample line from one of the passwd files: chrism:{CRAM-MD5}a67a65704086a046b3f875d1eaac8cb5c6fd13406507fead30d9bcb1bf… and to login through SASL I am trying to use the username chrism(a)example.com when I use the full email address like this to login like this I get this output into my postfix log: Jul 10 18:46:59 mail postfix/smtpd[57343]: connect from unknown[12.244.148.123] Jul 10 18:46:59 mail postfix/smtpd[57343]: NOQUEUE: reject: RCPT from unknown[12.244.148.123]: 554 5.7.1 <chrism(a)gmail.com>: Relay access denied; from=<chrism(a)example.com> to=<chrism(a)gmail.com> proto=ESMTP helo=<[192.168.1.14]> Jul 10 18:47:00 mail postfix/smtpd[57343]: disconnect from unknown[12.244.148.123] (not actually using example.com but I changed it here) heres my smtpd_recipient_restricitons from postconf smtpd_recipient_restrictions = permit_mynetworks, reject_unauth_destination, permit_sasl_authenticated so when I use the full user name (chrism(a)example.com) it doesn't appear to even attempt logging into the sasl server. If I change it to simply chrism, heres the output: Jul 10 18:50:36 mail postfix/smtpd[57356]: connect from unknown[12.244.148.123] Jul 10 18:50:38 mail postfix/smtpd[57356]: warning: unknown[12.244.148.123]: SASL CRAM-MD5 authentication failed: PDI3NjU4MTE4NDExMTQzN0BtYWlsPg== Jul 10 18:50:39 mail postfix/smtpd[57356]: lost connection after AUTH from unknown[12.244.148.123] Jul 10 18:50:39 mail postfix/smtpd[57356]: disconnect from unknown[12.244.148.123] if I put my user name in as chrism and don't add the @example.com it tried to login but it can't login. anyone have any ideas?

[Dovecot] Fixing lda user_query error introduces new fault in mail delivery

I was getting these errors below and after fixing it delivery errors were introduced dovecot/error_log ============== dovecot: Jul 11 06:19:28 Error: auth-worker(default): sql(user(a)domain.com): User query failed: Table 'postfix.users' doesn't exist deliver(user(a)domain.com): Jul 11 06:19:28 Error: BUG: Unexpected input from auth master: FAIL 1 dovecot: Jul 11 06:21:41 Error: auth-worker(default): sql(admin(a)achimota.com,127.0.0.1): User query failed: Table 'postfix.users' doesn't exist ============== It turns out that using prefetch with dovecot lda required a user_query in dovecot/sql.conf I fixed it by adding this query to dovecot/sql.conf user_query = SELECT concat('/var/vmail/', maildir) as home, 601 as uid, 12 as gid FROM mailbox WHERE username = '%u' AND active = '1' This resulted in a new mailbox /var/vmail/domain.com/user(a)domain.com being created when although /var/vmail/domain.com/user already exists and is what the query returns It seems that prior to that when the query was failing the mail was properly delivered somehow by dovecot, but fixing it created a new problem. It appears that the mail_location = maildir:/var/vmail/%d/%u in dovecot.conf could be related as %u is user(a)domain.com Is there a fix for this?

[Dovecot] Can Wiki entry on dovecot LDA/deliver be clarified?
by Frank Church 11 Jul '07

11 Jul '07

Hi guys, I am having some problems relating to this "Fixing lda user_query error introduces new fault in mail delivery" and I'd like to know if the above wiki comment holds even if a user_query is configured to return the correct mail folder. According to this LDA delivers only to the mail_location setting. Does that mean that it will stick to the value in dovecot.conf or will the value returned in the query override it? This appears to be the problem I am experiencing with the previous thread. >From wiki entry at wiki.dovecot.org/LDA ============================ Problems with deliver Currently deliver doesn't support namespaces. The mails can be delivered only to mailboxes specified by the mail_location setting. If you are using prefetch userdb, keep in mind that deliver does not make a password query and thus will not work if -d parameter is used. The UserDatabase/Prefetch page explains how to fix this. ================================== Any ideas? - Frank

[Dovecot] target doesn't allow inferior mailboxes
by Adam Williams 11 Jul '07

11 Jul '07

Using Seamonkey as my email client, and IMAP to check mail. If I create a new IMAP folder, and then delete it, I get the error: The current command did not succeed.

[Dovecot] About a simultaneous session of Dovecot(IMAP)
by Takateru Ueda 11 Jul '07

11 Jul '07

The construction of the mail server with Postfix+Dovecot(IMAP) is examined. ・The number of mailboxes is about 1000. ・The reception protocol uses IMAP and the Maildir form. ・OS is Redhat Enterprise Linux ES4. ・MUA uses Outlook Express. ・Postfix and Dovecot use latest Ver. In the above-mentioned environment, it is understanding person. how much the number of maximum sessions (number of people) that can be used at the same time becomes from MUA (When grounds of the calculation are understood, it is the best. )

[Dovecot] Connecting to dovecot/imap without a password
by Don Russell 11 Jul '07

11 Jul '07

I have written a script that connects (localhost) to the dovecot/imap server and performs various maintenance on my mail, by folder..... deleting old stuff, keeping the n most recent, that sort of crap, er good stuff. :-) My script is written in php (I use the various imap_* functions), and it connects to the imap server running on the same machine... is there a way to connect to the server without having to specify my user name and password? I was thinking there may be some form of "implied" logon if a request from user "don" requests to log on to user "don", then there's no need for a password check, when the connection is via localhost. That way I don't have to deal with userid/password related issues. :-) Thanks

[Dovecot] postfix pipe to deliver, null_sender.
by Erland Nylend 11 Jul '07

11 Jul '07

Hello, I just noticed a problem on our servers .. If I send myself a bounce, like this: | [en@mailserver ~]$ telnet localhost 25 | Trying 127.0.0.1... | Connected to localhost.localdomain (127.0.0.1). | Escape character is '^]'. | 220 mailserver ESMTP Postfix | helo foo | 250 mailserver | mail from: <> | 250 2.1.0 Ok | rcpt to: my(a)mail.address.tld | 250 2.1.5 Ok | data | 354 End data with <CR><LF>.<CR><LF> | testing | . | 250 2.0.0 Ok: queued as 673072767C | quit | 221 2.0.0 Bye | Connection closed by foreign host. Then the resulting mail message I get, has this header: | Return-Path: <MAILER-DAEMON> | Delivered-To: my(a)mail.address.tld | Received: from foo (localhost.localdomain [127.0.0.1]) | by mailserver (Postfix) with SMTP id 673072767C | for <my(a)mail.address.tld>; Wed, 11 Jul 2007 13:36:07 +0200 (CEST) | Message-Id: <20070711113611.673072767C@mailserver> | Date: Wed, 11 Jul 2007 13:36:07 +0200 (CEST) | From: MAILER-DAEMON | To: undisclosed-recipients:; It seems that postfix changes the return-path, and I dont see why it would do something like that. The bounce is not a bounce anymore, and if a user fetches the mail with e.g. fetchmail, and it cannot be delivered, then the bounce will be bounced, to MAILER-DAEMON .. My master.cf entry looks like this: dovecot unix - n n - - pipe flags=DRhu user=atmail:atmail argv=/usr/local/dovecot/libexec/dovecot/deliver -d ${recipient} If I add null_sender= , then that resolves it: dovecot unix - n n - - pipe flags=DRhu user=atmail:atmail null_sender= argv=/usr/local/dovecot/libexec/dovecot/deliver -d ${recipient} What do other postfix/dovecot-users do? Will this change break anything? I cannot see why empty null_sender isn't default .. so I'm wondering if there is something I've missed. Should we update the examples on http://wiki.dovecot.org/LDA/Postfix to include empty null_sender? -- Erland Nylend

[Dovecot] [Patch] Samba's proposed "ntlm_auth + winbind" support for dovecot-auth
by Dmitry Butskoy 11 Jul '07

11 Jul '07

The Samba team recommends to use their "ntlm_auth" command line helper for "NTLM" and "GSS-SPNEGO" authentication. This helper interacts with the Samba's winbind daemon, and this way can authenticate users against NT or Active Directory windows domain. Currently Dovecot can do "NTLM" authentication too, but just "locally" (against a local or sql database etc.). I've made a patch (attached), which adds "ntlm_auth" (or "winbind") support for Dovecot. The idea is to add two new authentication mechanisms: "mech_winbind_ntlm" and "mech_winbind_spnego". Both are coded in one additional file, "mech-winbind.c". An option "auth_ntlm_use_winbind" specifies whether to use the current implementation of ntlm, or do it by the "ntlm_auth" helper. "GSS-SPNEGO" always performed by the helper. Normally, "ntlm_auth" is invoked once, for all further requests. Such a way, "ntlm_auth helper from the Samba package, interacting with the Samba's winbind daemon", is used now by Squid, Apache and AFAIK some other applications. It is "strongly recommended" by the Samba team, and was already proposed even in this maillist 3 year ago (see f.e. http://www.dovecot.org/list/dovecot/2004-September/004775.html ). I hope there are no any serious performance issues for such a "complex way" -- f.e. with our web proxy, using this way, ~200 users do not feel any actual delays etc. I've successfully tested this patch with NTLM against AD domain. This patch can considerably improve the situation of "Email client on Windows desktop under Windows domain, but imap/pop at UNIX server". Currently, windows users have to specify their "login/password" for email accounts manually. There is an "SPA" (Secure Password Authentication) alternative for them, where just the desktop's login is used transparently, but it cannot be used now, because Dovecot cannot perform NTLM against, say, Active Directory domain. Since "dovecot-auth" daemon can be utilized by MTA as well (Postfix and other), the support of "ntlm_auth" in Dovecot can satisfy both SMTP and IMAP servers at UNIX side, and solve the issue completely. Questions and requests: - I try to code things most close to used style, i.e. using Dovecot's memory-management and io-pipe routines etc., but could someone look at it and check whether I've missed something or not? - Perhaps some names (of routines, modules) could be chosen better? - Maybe some other options should be implemented, i.e. "auth_winbind_helper_ntlm" and "auth_winbind_helper_spnego" to specify the helper's cmdline exactly ? - Currently I strip domain part of the username returned, i.e. from "DOMAIN\user" just to "user". Maybe better add some option "auth_winbind_strip_domain" for this? Certainly, it will be fine if someone else check it more, especially for "GSS-SPNEGO" which I cannot test for a while.

[Dovecot] NFS and Filesystem quota
by Joseba Torre 11 Jul '07

Hi, I've recently moved my mailboxes to a NFS share (on an emc Celerra), and, as expected, the quota extensions no longer works. However, I've read that adding http://dovecot.org/patches/quota-rquotad.c to $DOVECOT/src/plugins/quota, adding a line to $DOVECOT/src/plugins/quota/Makefile.am and rebuilding, it should work again.

[Dovecot] Migrating subscription lists
by Stewart Dean 10 Jul '07

10 Jul '07

I thought this would be relatively straightforward....I would create .subscriptions by doing an ls -1 of ~/mail. I'm running into some problems. 1) the ~/mail directories haves directories in them for 5% of the accounts! AFAIK, our mail sevice has always been UWIMAP with mbox format INBOXes, and it was my understanding that the mbox format is flat and NOT hierarchical and thus I'd have thought that ~/mail would be all folders and wouldn't have a directory with folders in it. Plus our users are not, as a rule, power/geek user that would understand even making subdirs in ~mail, so I don't know how this would have come to pass. Should this be? Or am I misunderstanding things? 2) Some people are consciously or unconsciously using the UWIMAP .mailboxlist subscription file as it is meant to be used, namely to *restrict* the folders shown. If/when I generated the Dovecot .subsbcriptions file by just doing an ls -1 of their mail directory, they will be surprised to see stuff not previously displayed....that they may very well not know they'd had. Murphy must be a terribly overworked deity...you'd think he'd take a rest now and then from maximizing entropy -- ==== Stewart Dean, Unix System Admin, Henderson Computer Resources Center of Bard College, Annandale-on-Hudson, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

[Dovecot] mbox vs maildir
by Don Russell 10 Jul '07

10 Jul '07

I'm using Dovecot 1.0.1-12 on Linux/Fedora 7 along with sendmail and procmail all running on the same box mail is stored in mbox format It's a small system with a half dozen or so e-mail "accounts". Each with 40-60MB of messages in various folders. I keep seeing messages about how mbox is antiquated and anybody with more than 100 messages etc should not use mbox, but use maildir instead. I'm not entirely convinced.... there seem to be pros and cons for each. Is there a discussion somewhere that really highlights why one format is so much better than the other? The last time I tried to convert from mbox to maildir, things got pretty botched up, no data loss, but it wasn't pretty. :-) Can Dovecot handle mbox for some users and maildir for others? I'd like to try a conversion for one user... I'll probably create a new user, then have procmail copy (via ! action code) all mail for one user to that new user. Thank you

[Dovecot] secure pop for outside pop inside
by arjan 10 Jul '07

10 Jul '07

Hi all, I've a server with dovecot running in secure pop mode. For connections from the outside world, I don't want to enable pop. However, this machine is also the host for a vserver. In this vserver I have a webserver running the WebGUI Content Management System. One can add content via email. For this the cms has to be able to check a pop emailbox. The cms doesn't support secure pop. It's not nescessary either, because dovecot and cms are on the same machine. How can I configure Dovecot in such a way that I can enable pop just for one ip-adress and have secure pop for connections on another adress? Any help would be very much appreciated. Kind regards, Arjan

[Dovecot] Tbird-DC state problem
by Stewart Dean 09 Jul '07

09 Jul '07

A experienced sysadmin who's doing some guinea-pig use of DC just ran into the following situation: 1) He brings up SeaMonkey 2) About 30 minutes later, he's in the middle of some involved messaging, mistakenly hits the redX in the top right of the SeaMonkey window, knocking himself out of SeaMonkey. 3) He immediately reinvokes SeaMonkey, all appeared to be OK Viewed some e-mail and some web page references, tries to send a message and then the Send hung for a time with a message "Sending Authenticate Info"..after some minutes, a new E-mail window appeared stating the "Server reported a timeout". As far as the message, it was apparently sent successfully, and saved in the Sent folder successfully. 4) He calls me in. I look through the syslog logging. There is nothing in the syslog critical stuff...and everything in the maillog looks normal. 5) He starts another message, tries to save it to Drafts and that hangs 6) I look more closely at the maillog and see a lot of logins (one a minute in some cases, but all appear to have been cleanly executed) plus one bunch of disconnected messages with one disconnected in idle in the period when the write to the Drafts would have been hung. Could it be that DC was in the middle of clean up in the initial disconnect/reconnect and SeaMonkey came back in the middle of it and one or the other's state tables got messed up (or both of them)? Shutting out of SeaMonkey, waiting a minute and reconnecting seems to have gotten things working again. Any comments? Anything I should be looking for? OTOH, this is the first real problem I've seen in some person-months of testing..... -- ==== Stewart Dean, Unix System Admin, Henderson Computer Resources Center of Bard College, Annandale-on-Hudson, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

[Dovecot] PHP implementation of dovecotpw passwords

09 Jul '07

I am looking for PHP functions that implement passwords that much the dovecotpw implementation. I downloaded one from PEAR, Crypt_HMAC, but the passwords it generates look nothing like the dovecotpw passwords, which could be my fault because I know nothing about the field. Is there a guide or some library that implements them to match dovecotpw?

[Dovecot] Virtual servers
by John Hedges 06 Jul '07

06 Jul '07

Hello I'm migrating from Courier to Dovecot (1.0.rc15) on Debian. I am trying to set up virtual servers based on the principal in this thread: http://www.dovecot.org/list/dovecot/2006-October/017165.html which suggests something like this to support multiple certificates: server foo { listen = 1.2.3.4 ssl_cert_file = /etc/ssl/certs/foo.cer } server bar { listen = 1.2.3.5 ssl_cert_file = /etc/ssl/certs/bar.cer } My virtual configs look like this: server mail.domain1.org { listen = 1.2.3.4 protocols = pop3 pop3s imap imaps ssl_cert_file = /etc/mail/hosts/domain1.org/ssl.crt ssl_key_file = /etc/mail/hosts/domain1.org/ssl.key auth default { mechanisms = plain passdb passwd-file { args = /etc/mail/hosts/domain1.org/userdb } userdb passwd-file { args = /etc/mail/hosts/domain1.org/userdb } } } server mail.domain2.org { listen = 1.2.3.5 protocols = imap imaps ssl_cert_file = /etc/mail/hosts/domain2.org/ssl.crt ssl_key_file = /etc/mail/hosts/domain2.org/ssl.key auth default { mechanisms = plain passdb passwd-file { args = /etc/mail/hosts/domain2.org/userdb } userdb passwd-file { args = /etc/mail/hosts/domain2.org/userdb } } } but I can't get ithis to work. Dovecot starts but authorisation fails. Is this kind of setup possible - is it possible to configure different passwd-files for connections on different IPs, or am I going to have to run separate instances of Dovecot for each virtual host? Thanks John

[Dovecot] Dovecot with iPhone
by Erik Dasque 05 Jul '07

05 Jul '07

Hi, anyone using their Dovecot server with an iPhone ? While the iPhone is able to see the Inbox, I can't get it to see the other folder. I have tried ~/Maildir, /home/ed/Maildir and Maildir as the IMAP prefix but to no avail. Anything I am overlooking ? Erik

[Dovecot] Index question
by Stewart Dean 05 Jul '07

05 Jul '07

The day I switch our user to dovecot and it goes into production, there will be a few thousand people all generating their indices for the first time (we have a legacy requirement for procmail, at least for now), so I wondered: 1) Is there is anyway to pre-emptively force indexing? 2) Is there any value in doing so? That is, will I gain much in terms of making the first time everyone connects to dovecot quicker (not that big initial wait)? -- ==== Stewart Dean, Unix System Admin, Henderson Computer Resources Center of Bard College, Annandale-on-Hudson, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

[Dovecot] Permission errors when creating/reading files in users' mail directories
by Bryan Wright 05 Jul '07

05 Jul '07

Hi folks, I'm trying to migrate an old uw-imap server to dovecot, and running into puzzling (to me) permission problems. I've configured mail_location as follows: mail_location = mbox:~/mail:INBOX=/var/spool/mail/%u and each user's mail directory has permissions like this: drwx------ 2 uid gid 4096 Jul 5 09:26 /home/uid/mail But when I try to check a user's mail using an imap client, I see the following error: Jul 5 09:59:49 imap dovecot: IMAP(uid): mkdir_parents(/home/uid/mail/.imap/ INBOX) failed: Permission denied If I open up the permissions so anyone can write, I find that the .imap directory is successfully created, and owned by "uid". Is dovecot initially creating the directory with some other ownership, and then changing the ownership to "uid"? I can get around this problem by setting INDEX in mail_location, and pointing it to a directory with more open permissions, but then I run into the next problem: Jul 5 09:25:49 imap dovecot: IMAP(uid): open() failed with mbox file /var/spool/mail/uid: Permission denied In this case, the permissions are set as follows: -rw------- 1 bkw1a mail 1267 Jul 5 08:47 /var/spool/mail/uid How should the permissions be set on the spool files?

[Dovecot] dovecot.conf pop3_uidl_format
by Peter Eriksson 05 Jul '07

05 Jul '07

From the Dovecot 1.0.1 sample dovecot.conf file: # If you want UIDL compatibility with other POP3 servers, use: # UW's ipop3d : %08Xv%08Xu ... # Note that Outlook 2003 seems to have problems with %v.%u format which was # Dovecot's default, so if you're building a new server it would be a good # idea to change this. %08Xu%08Xv should be pretty fail-safe. # # NOTE: Nowadays this is required to be set explicitly, since the old # default was bad but it couldn't be changed without breaking existing # installations. %08Xu%08Xv will be the new default, so use it for new # installations. # pop3_uidl_format = %08Xu%08Xv Notice the *very* small difference in the format between UW's ipop3d and the ones mentioned a little bit below? I think I just got bitten by this (we moved from UW's ipop3d to Dovecot). Loooots of users just got a lot of new (old) mail again ("Leave mail on server" is a popular setting). Ah well. They really should move to IMAP anyway and now they got some summer reading to do :-) Is the difference intentional? If so then perhaps this should be more clearly pointed out! - Peter

[Dovecot] dotlock O_EXCL query
by derek kit hoong foo 05 Jul '07

05 Jul '07

Hi there, I was wondering if someone can assist with clarifying why O_EXCL does not always work with NFS. Is it related to NFS protocol version support or export permissions mode out of the Celerra/Netapp ( e.g: mixed mode, unix file permissions ? ) Please advise. Thanks. Regards, new dovecot user.

[Dovecot] PAM timed out, kill failed, auth SEGV
by Thomas Arnett 04 Jul '07

04 Jul '07

My log is full of blocks like this: auth(default): pam(?): PAM child process 13576 timed out, killing it auth(default): PAM: kill(13576) failed: No such process Often, this is recorded for several pids at once. Occasionally, there's a single burst when a virtual user logs in, immediately before pam_authenticate() fails and checkpassword is executed. When this happens, pam() contains the username and remote IP. Usually, it starts 2 minutes after a login attempt (successful or not) and repeats every 10 seconds indefinitely. pam() contains something else: ~87% ? ~ 9% [garbage],master ~ 4% ?,master < 1% [empty] [garbage] varies; it seems to be constant for an instance of auth, but I haven't verified this. Eventually, auth segfaults: Core was generated by `dovecot-auth'.

[Dovecot] Maildir configuration vs ZFS and snapshots...
by Peter Eriksson 04 Jul '07

04 Jul '07

I have a little tricky issue around here. First some background: Every user is assigned their own ZFS filesystem, and it's mounted as /home/USER with a Maildir inside it. The there is a filesystem snapshot (read-only) taken automatically every day by the system. The idea is to allow users easy access to backup copies of their mail so that they can restore things themself.. For example this structure (somewhat abbreviated, some files/dirs removed): /home/testson/ .zfs/ snapshot/ 2007-06-18/ Maildir/ cur/ new/ tmp/ .Trash/ cur/ new/ tmp/ Maildir/ cur/ new/ tmp/ .Trash/ cur/ new/ tmp/ Now,I can access the normal Maildir INBOX and folders nicely via Dovecot/IMAP. The thing is I'd like to be able to access the snapshot too via Dovecot/IMAP somehow. My first idea was to use Dovecots namespace feature like this in the config file: namespace private { separator = / prefix = snapshot/ location = maildir:~/.zfs/snapshot/2007-06-18/Maildir:CONTROL=~/.dovecot/control:INDEX=~/.dovecot/index } This works great for the mail folders inside the Maildir - but not for the INBOX which isn't displayed at all... (Ie, under the "snapshot" prefix I only see "Trash" etc when looking at the folder from an IMAP client). I think that I'd need to use the "INBOX=" option for Dovecot to see the top-level "new/cur/tmp" directories in the snapshot folder, but you can only have one INBOX if I'm not mistaken? Any suggestions on how best to configure this? - Peter

[Dovecot] convert plugin: endless conversion and duplicate messages
by Andrew Ziem 03 Jul '07

03 Jul '07

Hi, When an mbox has a filename with a period, the Dovecot 1.0.1 convert plugin will endlessly convert the same mbox causing duplicate messages. To reproduce, create try converting two mboxes: one with a valid name and another with an invalid name. Then, repeat the login procedure a few times. Dovecot should do something more graceful such as replacing periods with another character. Here's /var/log/mail/errors Jul 2 08:29:44 aslan dovecot: IMAP(crystalp): Mailbox conversion: Couldn't create mailbox Print Shop Misc.: Invalid mailbox name Jul 2 08:39:46 aslan dovecot: IMAP(crystalp): Mailbox conversion: Couldn't create mailbox Print Shop Misc.: Invalid mailbox name Jul 2 08:48:54 aslan dovecot: IMAP(crystalp): Mailbox conversion: Couldn't create mailbox Print Shop Misc.: Invalid mailbox name Jul 2 08:48:58 aslan dovecot: IMAP(crystalp): Mailbox conversion: Couldn't create mailbox Print Shop Misc.: Invalid mailbox name Jul 2 08:49:39 aslan dovecot: IMAP(crystalp): Mailbox conversion: Couldn't create mailbox Print Shop Misc.: Invalid mailbox name Jul 2 08:59:40 aslan dovecot: IMAP(crystalp): Mailbox conversion: Couldn't create mailbox Print Shop Misc.: Invalid mailbox name Jul 2 09:09:40 aslan dovecot: IMAP(crystalp): Mailbox conversion: Couldn't create mailbox Print Shop Misc.: Invalid mailbox name Jul 2 09:20:23 aslan dovecot: IMAP(crystalp): Mailbox conversion: Couldn't create mailbox Print Shop Misc.: Invalid mailbox name I didn't test other non-{alphanumeric,whitespace} characters. Other than this and my previous e-mails, our conversion from UW-IMAP mboxes went nicely. I notice the performance difference, and our users will be happy to finally have proper subfolders. Andrew
