[Dovecot] imap process uid mapping question
by Chris Lea 13 Apr '06

13 Apr '06

Hi all. I'm new to dovecot. I promise I've looked over the docs and lists for an answer to this, but I didn't find anything. If I missed something I apologize. I'm running dovecot 1.0.beta2 on debian testing. It's almost working, I'm getting permissions errors when the imap server actually goes to read the messages out of the cur Maildir directory. The logs spit these out: dovecot: 2006-04-12 22:32:39 Error: imap(chl(a)iaminla.com): open(/var/vmail/iaminla.com/chl/cur/1144905139.V306I31c02bM482275.chldebian… failed: Permission denied The ls of that directory looks like this: chldebian:/etc/dovecot# ls -al /var/vmail/iaminla.com/chl/cur/ total 12 drwxrwsr-x 2 vmail vmail 4096 2006-04-12 22:12 . drwxrwsr-x 5 vmail vmail 4096 2006-04-12 22:13 .. -rw------- 1 vmail vmail 1098 2006-04-12 22:12 1144905139.V306I31c02bM482275.chldebian.chrislea.com:2, I have this line in my dovecot.conf mail_extra_groups = vmail so I assume that the process is running as some other user. My full dovecot.conf is here http://www.chrislea.com/dovecot.conf I'd really appreciate it if anyone has any ideas. Again, I apologize if this was already covered and I missed it.

[Dovecot] dovecot-dspam-plugin not launching dspam
by Stefan Schmidt 13 Apr '06

13 Apr '06

hello, i added the dovecot-dspam-plugin [1] to my dovecot-installation. when trying to move a mail out of or into the predefined spamfolder with thunderbird a messagebox shows : "dspam failed" and the message remains in its original position. i am using virtual mail users contained in a postgresql-database [2]. normal imap access and dspam training from the commandline works fine. a posting concerning probably the same issue has been posted on the dspam-mailinglist [3], but there haven't been any helpful replies so far. furthermore i suspect the plugin is missing the --user option when calling dspam, since this seems to be mandatory [4,5], but unfortunately adding this option in the plugin doesn't change its behavior. i am working on a debian system and currently using dovecot 1.0.beta3-3, dspam 3.6.4-2+b1 and the dspam-plugin "for dovecot beta 2 and 3". 1) calling dspam from the commandline with the same parameters as in the (slightly modified) plugin works fine :/# su virtual :/$ /usr/bin/dspam --user retrain --source=error --stdout --class=spam --signature=4,4434846e237406491211187 --debug -> /var/log/dspam.debug No QuarantineAgent option found.

[Dovecot] Dovecot-LDA & permissions
by Duncan Hutty 12 Apr '06

12 Apr '06

I set up postfix/dovecot with the dovecot-LDA according to the dovecot wiki, in particular: http://wiki.dovecot.org/LDA#head-dacb9b9a1f19c3ea86bb6f8caa3d64e3ddad9ef8 For separation of privileges, I want to have one uid per virtual domain rather than have the vmail user own all directories under the mailstore. Therefore the LDA, deliver, in order to deliver must fulfill one of the following: a) it must be started as root b) it must be setuid c) it must have write access to the user's mailstore even as an unprivileged user itself. But a) postfix declines to this: postfix/pipe[26267]: fatal: user= command-line attribute specifies root privileges which is probably a good thing. b) will work, but I'm really wary of making anything setuid c) could be done if the group that deliver runs as (as defined in the user= attribute in master.cf) is the same as the group of each mailstore directory and that this group has write permissions *and* the sticky bit of each mailstore directory is set so that the file created by deliver is owned by the uid of the mailstore owner not deliver's uid. This is not exactly a question as such because I believe, subject to a little testing, that I have a working mail setup. However, I believe in doing things the right way wherever possible and I'm sure someone must have come across this before, so I'm submitting to the list inviting comment. How are most of you doing this? Are you just using a single uid for all virtual users? -- Duncan Hutty System Administrator, ECE Carnegie Mellon University Please use informative subject lines

[Dovecot] password length
by Mark Richards 12 Apr '06

12 Apr '06

After setting up a very sweet Dovecot installation (with OpenLDAP) we're finding something strange: passwords are accepted but only the first 8 characters and anything less than 8 characters is an invalid password For several reasons, including allowing longer passwords to make them more difficult to crack, I'd rather be able to use longer passwords. LDAP seems to have attributes for minimum and maximum password lengths. Ours is set currently at 256 char maximum. So my guess is that Dovecot may be doing something, or there's a configuration item I missed. Checked all the docs and the wiki. Anyone? Mark Richards

[Dovecot] strip domains
by Netlink Tech 12 Apr '06

12 Apr '06

Hello, Running FC5 x86_64 with dovecot-1.0-0_8.beta3.rhfc5.at Using system user/passwds for 99.99% of users...have sql user/pass enabled to test virtual users from mysql. How do I strip off the domain when users provide user(a)domain.com so that my userdb and passdb use just 'user'? (disregarding sql auth...I'm not concerned with that right now). My dovecot.conf auth config: passdb pam { args = dovecot } passdb sql { args = /etc/dovecot-sql.conf } userdb passwd { } userdb sql { args = /etc/dovecot-sql.conf } Can I just pass userdb the 'user' using an args= statement? %d? ...and then also to the passdb? Thanks, Curt

[Dovecot] Re: strip domains
by Roger Weeks 12 Apr '06

12 Apr '06

So if I understand this correctly, %u matches the whole username in the sql database, but %n only matches the name before @? One thing we discovered in migrating from courier-imap to Dovecot is that courier-imap supported user@domain as a valid login name, where by default using %u in the SQL query, Dovecot does not. So it would have been useful for us to avoid a number of tech support calls for users who have user@domain configured in their mail clients. -- Roger J.

[Dovecot] Full text search indexing
by Timo Sirainen 12 Apr '06

12 Apr '06

SEARCH is probably the slowest command that Dovecot has, especially when searching texts from message bodies. There exists a lot of text search engines, but unfortunately as far as I know there exists only one that can be used with IMAP. The reason why IMAP is special is because it requires that when searching eg. "ello", it must match also mails which contain eg. word "hello". Most search engines support only matching either complete words or matching from the beginning of the words. So, the one usable engine which I know of is Cyrus's squat indexing. It works basically by indexing the mails in 4 byte blocks and storing them in a trie. So if there exists a string "he llo", it indexes "he l", "e ll" and " llo" strings. When searching it then gets the first 4 bytes of the search keyword, looks them up from the squat index and then once it gets a list of matched mails, it reads the mails and does a proper search for only them. So the squat index doesn't give exact results, but only narrows down the number of mails which have to be searched. The biggest problem with those squat indexes is that it doesn't support incremental updates, so there has to be some nightly runs to rebuild the indexes from scratch. And with lots of users that's not practical, so I think that's the reason why the squat indexes aren't all that commonly used with Cyrus. I was thinking about taking the basic ideas from the Cyrus squat indexer but making it possible to update it incrementally so Dovecot could do it automatically. Also to reduce space I was thinking about sorting the 4 byte strings so instead of eg. "abcd", "dcba" and "abdc" all being indexed, they could all be stored as "abcd" (so the search key would also have to be sorted before use). But that might cause larger result sets making the search slower, so I'll have to test if it's worth it. Unicode characters might also be a problem. If the characters are stored in 16bit characters, it would waste space. If they're stored in UTF-8 the 4 bytes might not be enough to give a useful index (as a single character might take even 5 bytes). One thing I was thinking was to not index in 4 byte blocks, but 4 character blocks in UTF-8, so the trie could be 4..20 levels deep depending on what unicode characters are used (in finnish text it would probably be max. 7 levels deep). So, now would be a good time to tell if you can think of some better ideas how to do this, especially if you know about some new algorithms specifically designed for this kind of searching. :) Pretty much all the algorithms I've found about this were suffix trees/arrays and this basic trie thing.

I'm not asking for every new feature, just one that I think fits in with the current design of dovecot already and is a standard feature provided by other servers. You already provide the ability built in to "strip domains" per say, with the %u and %d values built in. To accomplish what I would like to do, I only need to be able to pass whatever combination of these values I wish to my passdb and userdb functions of choice. Regards Michael Baird

[Dovecot] [patch] MD5 variable modifier
by Ben Winslow 12 Apr '06

12 Apr '06

Hello, I've taken a different (better) approach to getting tpop3d-compatible UIDLs: the first attached patch (...md5_modifier.diff) adds a variable expansion modifier (%M) to return the md5sum of the expanded variable in hex. With the patch, you can get tpop3d-compatible UIDLs by setting pop3_uidl_format to %Mf. While testing interactions with other modifiers (e.g. %MUf to get the md5sum in uppercase), I noticed that %U is broken -- it lowercases the input just as %L does. The second patch (...ucase_modifier_fix.diff) is a one-liner to fix that. Finally, the third attached patch (...apop_aesthetics.diff) is another trivial patch to add a space between the server greeting and the APOP challenge. I think it looks better when telnetting to the server to diagnose something, and since spaces are stripped from the end of the login_greeting, editing the code is the only way to add the space. Cheers, -- Ben Winslow <rain(a)bluecherry.net>

[Dovecot] DON'T DELETE THIS MESSAGE?
by Knute Johnson 12 Apr '06

12 Apr '06

I have a new install of FC5 running dovecot 1.0.0 beta 2.7. I get my mail with POP3 but I have a user using IMAP. They both work great but I keep getting a message from dovecot in my mail saying DON'T DELETE THIS MESSAGE -- FOLDER INTERNAL DATA. I think it is there to help keep track of IMAP messages. Since I use POP3 is there any way not to have it show up all the time? I've deleted it, I've deleted my account and re-added it but it keeps coming back.

[Dovecot] IMAPS - timeout while moving mails
by Petar Bogdanovic 12 Apr '06

12 Apr '06

Hi, I'm using Dovecot v1.0.beta5 (NetBSD 3.0, i386) and Mozilla Thunderbird 1.5 (XP, i386). My dovecot.conf is pretty simple, because I just use dovecot for me as the only user. However, when I try to move a 'larger' amount of mails (>200) from my local TB-mbox to the remote IMAPS-storage, the process hangs after about 150 - 160 transferred mails (the 'blocking' mail is _never_ the same). I don't have the slightest clue why - there is nothing in the logs - even if I turn 'verbose_ssl' on. After a while, TB tells me, that the server timed out and dovecot says: "imap(petar): Disconnected" Usually - if I close my MUA correctly - dovecot says: "imap(petar): Disconnected: Logged out" Is somebody maybe experiencing something similar? Thank you very much & with kind regards, Petar Bogdanovic

[Dovecot] 1.0beta5 released
by Cesar Mesias 12 Apr '06

12 Apr '06

Dear friends, I am trying to upgrade dovecot 1.0-alpha3 to dovecot 1.0-beta 5, but I have some problems to do that. When I install its rpm I get a message which indicates I have to install some dependences such as openssl-0.9.7f-7.i386, sqlite-3.2.8-1.9.el4 and libk5crypto.so.3. I haven't had any problems with openssl and sqlite but I always get a message that I need to have the libraries of libk5crypto. I realised that I have these libraries, but I get the same message, which is the following: [root@server]rpm -ivh openssl-0.9.7f-7.i386.rpm warning: openssl-0.9.7f-7.i386.rpm: V3 DSA signature: NOKEY, key ID 4f2a6fd2 error: Failed dependencies: libk5crypto.so.3(k5crypto_3_MIT) is needed by openssl-0.9.7f-7.i386 libkrb5.so.3(krb5_3_MIT) is needed by openssl-0.9.7f-7.i386 I appreciate so much if you could send me the steps that I have to do to make the upgrade without problems. I have Red Hat Enterprise Linux 4.0 I am looking forward from hearing you soon. Thanks for your time. Regards, Cesar

[Dovecot] phantom new mail (mailboxes keep on being reported as having new mail)
by Grobian 11 Apr '06

11 Apr '06

Hi, I'm using dovecot 1.0_beta3 on Gentoo Linux, and am experiencing a problem of what I call 'phantom mail'. This problem I have for a long time (pre 1.0), but at the moment I'm using 1.0_beta3 and the problem still is in there. My setup is as follows: - regular x86 box - running Exim and Dovecot - Exim saves new mail in maildir format in a local filesystem /mail/user/blabla - Dovecot reads and serves IMAP from local filesystem /mail/user/blabla - client is Mutt and/or Thunderbird from any OS (Mac, Linux, Windows) via IMAP Situation that happens: I get new mail in a folder, say =news (in Mutt style, it's .news dir in the maildir directory). I read the item, Mutt (or Thunderbird) marks the item as read (moving it over to cur aswell I think), save the folder, then move on to another folder. At this point dovecot IMAP server indicates to the client that there is new mail in the folder =news. If I visit the folder with the client, I see no new mail, and sometimes I have two or three of those folders, and I can keep on cycling with Mutt till I get bored :). Before upgrading Dovecot, I knew of no way to resolve this problem; eventually, it seemed that at some point the folder seemed to figure out itself that there was indeed no new mail. Sometimes I could trick it by letting Mutt mark the mail as new again, and then save the folder. Didn't always work. Now, I think a week or two ago I upgraded Dovecot and had to manually move all the .subscription files, and I also in one go decided to remove the dovecot* and .imap* files. That cleaned up, and at first that looked like it solved my problem. Not. So I figured out throwing away dovecot's index stuff (rm dovecot* in the directory that shows phantom mail) resolves the problem. However, this method starts to get annoying so to say. So, I did some investigation and found out that the dovecot-uidlist file seems to be not up-to-date on a folder that shows phantom mails: # awk '{ print $2 }' dovecot-uidlist | sort > tmp.uids # ls cur | sort | diff -u - tmp.uids --- - 2006-03-08 17:45:26.428168000 +0100 +++ tmp.uids 2006-03-08 17:45:19.000000000 +0100 @@ -47,4 +47,5 @@ 1141340181.H111425P8973.hermes.orakel.ods.org:2,S 1141387968.P13010Q0M35974.hermes:2,S 1141528391.H769531P12886.hermes.orakel.ods.org:2,S -1141830301.H349821P23427.hermes.orakel.ods.org:2,S +1141544380 +1141830301.H349821P23427.hermes.orakel.ods.org It seems the dovecot uidlist doesn't have the right name for the file on disk, probably therefore "seeing" a new file all the time and reporting the folder as having new mail. The 1141544380 entry comes from the first row of the dovecot-uidlist file: 1 1141544380 51 I guess it's just some sort of line to keep track of the last timestamp and the number of messages or something. If my theory is right here then it looks as if the 'bad entry' is actually more recent than this most recent timestamp reports. But this is only speculation of course. Enough for this lenghty mail I guess. Is this a known issue, or can it be caused by the way I set up my system? I must note that this only happens for some folders, not all of them. I have folders which get a lot of mail, but don't have this happening on. Any clues go resolve this are welcome. Regards, -- Fabian Groffen

[Dovecot] SSHA Password Hashing
by Gavin Young 11 Apr '06

11 Apr '06

We are currently running a production mail server using version 0.990.99.11-2 (latest RPM from RHEL/CentOS). We would like to migrate more virtual domains off our courier imap server to dovecot but the courier imap user passswords are stored in LDAP and are SSHA hashed which is not supported by our current version of dovecot (CRYPT only). >From reading the mailing lists this feature is now available but I am hesitant to move a production server to a beta software release. Apart from waiting for a 1.0-final RPM, what is the simplest/best way for us to allow dovecot to read existing SSHA hashed passwords within LDAP? Any help would be much appreciated. Gavin

Before trying to Luis' suggestion, I had the following in /var/log/messages: dovecot(pam_unix)[4691]: check pass; user unknown dovecot(pam_unix)[4691]: authentication failure; logname= uid=0 euid=0 tty= ruser= rhost= dovecot-auth[4691]: pam_ldap: could not open secret file /etc/ldap.secret (No such file or directory) I suppose the first two entries are the lookup for the dovecot user in the DS, where it doesn't exist. And since I want anonymous binds to the DS, I haven't created file /etc/ldap.secret. Users were able to authenticate and get their mail. After changing to auth_userdb = passwd, all the messages went away, but the users weren't able to get their mail: Evolution gave me the following error: "Unable to get a valid greeting" from the mailserver. I went back to auth_userdb = ldap /etc/dovecot-ldap.conf, and then back to auth_userdb = passwd. Users can get their mail, but the messages are back in the log file.

[Dovecot] Dovecot's as server based and mail filters and addressbooks holder?
by Sysadmin 10 Apr '06

10 Apr '06

Hello. I'm just wondering, that maybe is the time to change the imap -s format or add some more features, are in these day's most people, me also are so called mobile users. And imap is good solution for us but however still some basic things are missing, fore example: 1) Server side mail filters. I read mails from home, from office and from webmail. Now when I need to make mail filter, for example to collect all dovecot mails into one subfolder, I can do it in one computer, and they works, if the computer is online, but if I need to change them, reading email from the another computer, I can't do it. 2) Server side address book. Yes, I know, ldap is solution, but installing and configuring the ldap server for some simple global address book, is kind of overkill. And these rules/address book can be from client to see as subfolder, so every imap capable client can deal with them? Is this real on not? -- Sysadmin

[Dovecot] Missing X-IMAPbase header causing mbox corruption
by Con Tassios 10 Apr '06

10 Apr '06

If the first message in an mbox is deleted by an external program, therefore removing the X-IMAPbase header, an error such as the following occurs. Apr 9 20:10:51 sm1 dovecot: imap(306812): file mbox-sync-update.c: line 460 (mbox_sync_update_header_from): assertion failed: (ctx->mail.uid == 0 || ctx->mail.uid_broken || ctx->mail.uid == mail->uid) This prevents the user from logging in, but also appears to cause mbox corruption. If the X-IMAPbase and the X-UID headers are missing, Dovecot will insert them successfully, but fails to do so when only the X-IMAPbase header is missing. Using dovecot-1.0.beta3.

[Dovecot] quota reporting
by Mick T 10 Apr '06

10 Apr '06

Hi all, I'm wondering if theres a way to report the quota, but not enforce it? The problem is that i'm using dirsize as the quota method to calculate the size of the mail directory, and for very large mailboxes this can take time... what i thought would be good, would be if dovecot could report the quota when the user requests it, but doesn't calculate it for every operation it performs? Does any one have any suggestions? I'm using Dovecot 1.0 beta5 My config: mail_plugins = imap_quota quota The quota for a mailbox is stored in sql, and so the sql query returns a "quota" which is picked up by the quota plugin Michael

That might explain why it won't compile, however - gnutls is mentioned in the config help and also in the readme; "Dovecot supports both GNUTLS and OpenSSL.

[Dovecot] dovecot won't compile for GnuTLS

Hi! I'm currently investigating a switch from courier-imap to dovecot since a number of our users experience problems with Outlook in combination with SSL. I can compile dovecot with openssl support and it runs "fine" except that the Outlook issues are still there. I read that dovecot works best with GnuTLS and thought that I'd try to compile for that instead. The system is running SuSE 9.3. I've installed the gnutls-library and configure runs fine, but make stops. My configure arguments is ./configure --with-vpopmail --with-ssl=gnutls Make stops with the following info: make[3]: Entering directory `/usr/src/qmail/dovecot-beta-test/dovecot-1.0.beta5/src/master' /bin/sh ../../libtool --tag=CC --mode=link gcc -std=gnu99 -g -O2 -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -o ssl-build-param ssl-init-main.o ssl-init-openssl.o ssl-init-gnutls.o ../lib/liblib.a -lgnutls -lgcrypt gcc -std=gnu99 -g -O2 -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -o ssl-build-param ssl-init-main.o ssl-init-openssl.o ssl-init-gnutls.o ../lib/liblib.a -lgnutls -lgcrypt ssl-init-gnutls.o(.text+0x93): In function `_ssl_generate_parameters': /usr/src/qmail/dovecot-beta-test/dovecot-1.0.beta5/src/master/ssl-init-gnutl s.c:34: undefined reference to `gnutls_dh_params_generate' ssl-init-gnutls.o(.text+0x11d):/usr/src/qmail/dovecot-beta-test/dovecot-1.0. beta5/src/master/ssl-init-gnutls.c:57: undefined reference to `gnutls_rsa_params_generate' collect2: ld returned 1 exit status make[3]: *** [ssl-build-param] Error 1 make[3]: Leaving directory `/usr/src/qmail/dovecot-beta-test/dovecot-1.0.beta5/src/master' make[2]: *** [all-recursive] Error 1 make[2]: Leaving directory `/usr/src/qmail/dovecot-beta-test/dovecot-1.0.beta5/src' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/usr/src/qmail/dovecot-beta-test/dovecot-1.0.beta5' make: *** [all] Error 2 Any clues?

[Dovecot] ssl-parameters.dat ownership problems on MacOS X

[Dovecot] Feature Request: Config Dump
by Charles Marcus 09 Apr '06

09 Apr '06

Hello, One of the less friendly lists I am on is the Postfix list, but one of the features that Postfix has, and the use of which is required when asking for help on their list, is a command called 'postconf', which simply dumps the current configuration parameters into a neat, orderly output that you can then cut-n-paste into an email request for help. The postfix guys won't even try to address a problem without this output (as opposed to snippets from config files), combined with log snippets of the failing behavior (as opposed to bounced message text, or 'it don't work' comments). So, what I'd like to see is something similar - a command that I can issue that will cause Dovecot to dump all of the configuration parameters it is currently using in a neat, orderly arrangement. This would dramatically help individual users in troubleshooting their own problems, as well as help people on this list help others. It would totally eliminate all of the 'what is xys set to' questions back and forth. But I'm more interested in how it will simply help me to see how I have it configured, and allow me to easily spot conflicting or misconfigured parameters. -- Best regards, Charles

[Dovecot] dovecot NTLM authentication
by Lior Okman 09 Apr '06

09 Apr '06

Hi, I'm trying to configure DoveCot to allow NTLM authentication. I've successfully authenticated with Outlook 2003 against Dovecot when the passdb backend used to store the password is a passwd-file. It doesn't matter if the passwd-file contains plain or NTLM encrypted passwords. When I compare the NTLM hash provided by the dovecotpw utility to the one I have in my SAMBA ldap, it appears to be exactly the same. When I use the LDAP passdb backend, I can see in the log file that dovecot has received the correct NTLM hash value, but outlook fails to authenticate successfully. I'm using the debianized dovecot version v1.0.beta2. I can post my dovecot-ldap.conf file, if it will help. Can anybody help me configure my dovecot to allow Outlook to perform NTLM authentication when the password database is in LDAP? Thanks, Lior Okman

Hello, I have dovecot setup to pull passwords stored in plain from a database. My allowed authentication mechanisms are cram-md5 and digest-md5. Cram works but digest fails on my evolution client with and authentication failed. The server is running dovecot 0.99.14-1 on debian sarge. The user logging in is test(a)advanced-reality.com. Some potentially relevant portions of dovecot.conf are: auth_mechanisms = digest-md5 cram-md5 auth_default_realm = auth_user = dovecot-auth >From the logs with auth_verbose = yes and auth_debug = yes in dovecot.conf: Mar 16 08:12:51 localhost dovecot-auth: PGSQL: Performing query: SELECT password FROM mailbox WHERE username = 'test' AND domain = 'advanced-reality.com' AND active IS TRUE Mar 16 08:12:51 localhost dovecot-auth: digest-md5(test(a)advanced-reality.com): password mismatch Mar 16 08:12:51 localhost pop3-login: Aborted login [64.81.224.97] Some preliminary searching led me to this: http://www.dovecot.org/list/dovecot/2003-November/002598.html Is there a problem with digest-md5 in this version of dovecot? Any pointers on how to troubleshoot this further? Any additional help is appreciated. Let me know if additional information is needed.
