[Dovecot] header search for splitted word
by Kazuo Moriwaka 06 Jan '05

06 Jan '05

Hello, I wrote a patch for header search about a word over two lines. Please check it. For example, following header string contains a word splitted into two mime encoded block. It's normal behavior of MUAs in CJK environment. Subject: =?ISO-2022-JP?B?Sk1CGyRCJUQlIiE8JUslZSE8JTkhIRsoQkpBTBskQiVBJWMhPCU/GyhC?= =?ISO-2022-JP?B?GyRCITxKWCRHOVQkLxsoQiAbJEI0WjlxGyhCLxskQiVRJWklKhsoQi8bJEIlNSUkJVElcxsoQg==?= And now, dovecot search command miss to search the word. word : "ABCDE" MIMED : "AB\r\n\tCDE" search(now): "AB CDE" this patch: "ABCDE" This patch has a bad side effect that in English or other languages, two words is connected. For example, > This is a > sample. matches to "asample". I think this is not a big problem, but if there is a good solution, please let me know. best regards, -- Kazuo Moriwaka moriwaka(a)valinux.co.jp Index: src/lib-mail/message-header-search.c =================================================================== RCS file: /home/cvs/dovecot/src/lib-mail/message-header-search.c,v retrieving revision 1.13 diff -r1.13 message-header-search.c 149c149 < chr = ' '; --- > chr = '\t'; 153c153 < if (chr == '\r' || chr == '\n') --- > if (chr == '\r' || chr == '\n' || chr == '\t')

[Dovecot] possible bug with mail->get_header and caching?
by Johannes Berg 06 Jan '05

06 Jan '05

I don't know if this is intended or not, but here it comes. I have * that copy plugin I was working on * dovecot 1.0-test59 * thunderbird test client My copy plugin looks for the X-DSPAM-Signature header line, and reports it to syslog as such: imap: we have a signature: "X-DSPAM-Signature: <sig>" where <sig> is replaced by what is found in the header line. This only happens when I copy in/out of the SPAM folder (which works fine). Now, when a mail is copied from INBOX to SPAM that doesn't have the signature line, I return an error to the client saying the user can't do that copy since the signature line is necessary. I detect the condition of not having that signature line by checking like this: if (!(signature = mail->get_header(mail, "X-DSPAM-Signature")) { ... return error ... } This works fine, error comes back. Second try, copying a mail that has the header line: works. So, lets do some code changes, disconnect and reconnect to reload the plugin. All of a sudden, copying mails that don't have the header line works too! Uhh? Lets go looking at syslog: imap: we have a signature: "X-DSPAM-Signature: " The only rational explanation I could come up with is that dovecot caches the header line and somehow decided that since it knows about the X-DSPAM-Signature header line mails that don't contain it should have an empty version of it. Well, I can of course test for this (and I actually should anyway, an empty signature isn't useful to dspam), but I do think this is a bug since it makes distinguishing between empty and non-present header lines impossible.

[Dovecot] PostgreSQL user database
by Marco Herrn 06 Jan '05

06 Jan '05

Hi, I am using postgresql for my password and user databases. The problem is, that the information needed in the user database is held in more than one table. But it seems to me that dovecot expects to get all the information for mailbox, uid, gid and home in _one_ query. Is there a way to get around this? Maybe even getting some of this information by another way than pgsql (this is more a rethorical question, since I have this information in the DB, but sometimes it is useful to get, for example the location of the mailbox by another way than the uid and gid). But my primary question is if I can set these fields in different queries. Regards Marco -- Every word is like an unnecessary stain on silence and nothingness. -- Marco Herrn _ ___ o ' (_)< _ _ _>(__'> o 0 (_X % >(_`> O o _; _;'7^'_ \;\ % (GnuPG/PGP-encrypted mail preferred) _;\ _.\ _.';;) ;,;_/; Key ID: 0x94620736 _ _'./_$'))_; );/$}/`fsc

[Dovecot] virtual hosting
by Tom Allison 06 Jan '05

06 Jan '05

I'm trying to figure out how I might set up some virtual hosting accounts for my server. domain1 would be delivered via procmail to ~/Maildir mail directories domain2 would be delivered via postfix to /var/mail/vhosts/domain2/username and similarly for additional domains. There's also one domain that's delivered to another machine, but that's not a dovecot issue. I just mention it for completeness. currently I have only domain1 and only: default_mail_env = maildir:~/Maildir I'm not really sure how to set this up for additional locations of maildir:/var/mail/vhosts/%d/%n/Maildir (This seems right?) Right now I'm wondering if I have to do one of the following: create two instances of dovecot with seperate configuration files? move everything to /var/mail/vhosts/%d/%n/Maildir data structure and the rewrite all my local (~/Maildir) procmail rules to manage delivery.. This is seeming sticky?

[Dovecot] why dovecot try to access the uses's home?
by Farkas Levente 06 Jan '05

06 Jan '05

hi, after i try to use dovecot with ldap i configure dovecot as: ------------------------ first_valid_uid = 499 last_valid_uid = 499 first_valid_gid = 499 last_valid_gid = 499 default_mail_env = maildir:/home/mail/%d/%n auth_userdb = static uid=499 gid=499 home=/home/users/%d/%n auth_passdb = ldap /etc/dovecot-ldap.conf ------------------------ but after this i've got the error in imap.log: ------------------------ dovecot: Dec 29 14:39:14 Fatal: chdir(/home/users/<username>) failed with uid 499: Permission denied ------------------------ i see the reason since each user has it's own uid and uid 499 can't access to the users home which has 0700 access right. but why dovecot would like to access the user's home? does it nessesary? since in this case one static uid can be usable or this uid has to be read (write?) access to all user's home. is there any usage of static uid in this case? yours. -- Levente "Si vis pacem para bellum!"

[Dovecot] 0.99.1[12] IMAP problems with Apple Mail.app?
by Jim Tittsler 06 Jan '05

06 Jan '05

Is anyone else having trouble using the Apple OS X Mail.app with a Dovecot IMAP server? With 0.99.11 and 0.99.12 attempting to read certain messages using IMAP or IMAPS seems to put Mail.app into spinning pizza of death mode. Sniffing the connection, it looks like it happens after the client issues a BODY.PEEK[] and the server has responded with the (UID XXXX BODY[] {YYYY}...) and OK Fetch completed. I've only been able to catch it happening with messages that are either (a) Base64 encoded or (b) those that claim to be multi-part/alternative, but only seem to contain a single part. The client acts like it has received the message, since if I kill Mail.app and restart it, I am able to read the problem message from its cache. Is this a Mail.app bug? Is it something about the way Dovecot is responding to the BODY.PEEK[] in these cases? Using Mail.app with the Novell myrealbox.com IMAP I haven't seen problem, even with a test problematic message I redirected there, although admittedly I'm changing the headers by doing the redirection. I haven't gotten 0.99.13rc3 to get past the autotools stage of complaining about AM_ICONV (and a number of AC_ warnings), so I've yet to try it.

I have a question regarding dovecot (1.0-test52) and pop3. I have users that do not have home directories, they only have an inbox in /var/mail. When they try to pop their email, dovecot tries to create ~/mail and then fails. Is there a way around this or will all email users need to have a home directory?

v0.99.13 2005-01-06 Timo Sirainen <tss(a)iki.fi> * GNUTLS support hasn't been working for a while, so it's not even tried to be used anymore unless explicitly wanted. + Added CRAM-MD5 authentication mechanism. Patch by Joshua Goodall + Added SMD5 and LDAP-MD5 password schemes and changed MD5 scheme to use LDAP-MD5 if the password isn't in MD5crypt format. Patch by Joshua Goodall + Workaround for some POP3 client bugs: if message doesn't contain the "end of headers" empty line, add it automatically. + vpopmail supports now all password schemes, most importantly MD5crypt works now without support from libc's crypt() - SQL and LDAP authentication was broken - SEARCH UNKEYWORD wasn't working

[Dovecot] authenticate authenticated users
by Tzafrir Cohen 05 Jan '05

05 Jan '05

Hi I'm using dovecot on a LAN server. I sometimes read mail from the server itself locally with mutt and sometimes remotely with mutt or mozilla . I would like to avoid typing my password whenever necessary but without writing a plain-text equivalent copy of it locally. It feels quite silly to have to type the password locally becase the imapd does not know that the process is indeed a process of the user tzafrir. It has all the information it neeeds to check that. wu-imapd has something called "pre-authentication": the imapd is run by the user unpriviliged to access mail in the user's home directory. As a bonus this works quite nicely with ssh public key authentication. I know that at least mutt and pine support running a custom command for creating an imap connection. But then again, wu-imapd is built quite, well, differently. Any ideas? -- Tzafrir

Test58 and test59 breaks "compact folders" and "expunge" in thunderbird and evolution. Messages marked for deletion just sit there as if compacting folders or expunging have no effect. Thunderbird continues to behave erratically with dovecot test builds. I haven't been able to test the imap_client_workarounds=tb-negative-fetch option yet as I'm still running test52.

[Dovecot] PLAIN-MD5 passwords?
by Peter Clark 03 Jan '05

03 Jan '05

After I found out that {CRYPT} doesn't support passwords longer than 8 characters, I decided to switch over to MD5 for user passwords in my LDAP database. However, while I have no problem with Postfix + SASL, Dovecot fails to authenticate. Relevant bits from /etc/dovecot-ldap.conf: user_attrs = mailAddress,,,,, # The search string is identical to what's found in /etc/saslauthd.conf: user_filter = (&(|(uid=%u)(mailAddress=%u))(status=active)) pass_attrs = mailAddress,userPassword pass_filter = (&(|(uid=%u)(mailAddress=%u))(status=active)) default_pass_scheme = PLAIN-MD5 When I try to connect using either KMail or SquirrelMail (which worked just fine before I switched schemes), the following error appears in /var/log/syslog: ldap(user(a)mydomain.tld): password mismatch But when I try 'testsaslauthd -u user(a)mydomain.tld -p longpassword' it authenticates just fine. I have the line 'password-hash {MD5}' in /etc/ldap/slapd.conf, and I used 'slappasswd -h {MD5}' to create the MD5 versions of the passwords. Dovecot is v. 0.99.11. If I can't figure out how to get it to work with MD5, I guess I'll have to go back to CRYPT, but it would be nice to have longer passwords... :Peter

[Dovecot] Wanted: gnutls11 support
by Jaldhar H. Vyas 03 Jan '05

03 Jan '05

I talked to Timo about this before and even provided the beginnings of a patch but don't have enough time to really do a proper job. Anyway, dovecot doesn't work with recent versions of the GNU TLS library. As a result, I compile the Debian package with OpenSSL. However some of the other libraries used, such as OpenLDAP are linked against GNU TLS so Dovecot is linked against both. And it is suspected this is leading to bugs. So could some kind soul provide Timo with a patch he can include in 0.99.13? -- Jaldhar H. Vyas <jaldhar(a)debian.org> La Salle Debain - http://www.braincells.com/debian/

That last line actually made it possible for me to be able to log into the server :) I am still getting errors from PAM but it starting to look good. Is there a good HowTo on setting Dovecot to comunicate directly to MySql without using PAM in the middle ? Also, Since Postfix is still not working on my server, I can't actually recive Emails. Is there somewere an example of the files that need to be in the maildir that I can put them in there and test that the email client get's the mail out ?

[Dovecot] SASL AUTH
by Tom Allison 02 Jan '05

02 Jan '05

I'm reading through the dovecot wiki pages for virtual hosting with postgresql/postfix/dovecot/debian and it looks pretty nice but I think I'm going to skip the SASL authentication since I'm in a trusted network. I think all I need to do is skip section 5 entirely and bypass all the sasl references in the postfix section. Technically, I don't think any of the SASL has much to do with the dovecot configuration.

[Dovecot] random pool depletion
by Johannes Berg 31 Dec '04

31 Dec '04

I'm facing a problem with dovecot 1.0 test-59; ever since I installed it and use it my random pool is always depleted whenever someone opens an imap connection. This wouldn't be too bad if the machine was used interactively, but since it is not and other services read directly from /dev/random those are sometimes blocked due to dovecot depleting the pool by reading /dev/urandom. Thus my question: is it really necessary to use random numbers from /dev/urandom for temporary filenames? And even if, couldn't it use less? It apparently uses 8 bytes every time. johannes

[Dovecot] delivery agent in 1.0?

[Dovecot] Authentication difficulties
by Timo Sirainen 30 Dec '04

30 Dec '04

There are constantly pretty basic questions in this list (and in my inbox) about how to get user authentication work correctly. This means that the documentation how it all works is either bad, or people don't find it easily. Any ideas how to improve it? I did this now: - Documentation link in dovecot.org now points directly to Wiki, so people don't go read the outdated documents - Upcoming 1.0-tests and 0.99.13 will contain doc/USE-WIKI-INSTEAD file pointing to Wiki: http://dovecot.org/list/dovecot-cvs/2004-December/003928.html - Updated comments in dovecot-example.conf: http://dovecot.org/list/dovecot-cvs/2004-December/003924.html - Added pointers to Wiki in dovecot-example.conf: http://dovecot.org/list/dovecot-cvs/2004-December/003927.html How good are the Wiki documents about user authentication in general? The content should probably be split somehow to "getting started" vs. "everything there is to know about it" and "system users" vs. "virtual users". I'm not really sure how to best do that though. I think the Wiki in general could be better organized. Wish I knew how.

[Dovecot] Maildir owner importance
by Roi Efrati 29 Dec '04

29 Dec '04

I have set up a directory (/var/local/virtualdir/) as the maildir with a special user/group (virtualmail) and in it I create directories for each domain (example1.tld, example2.tld etc) and sub dir's for each mailbox). Only at the moment, apart from the first one, they are all created as with user root as the owner. How important is to have all the directory tree owned by the same user group (virtualmail:virtualmail) ?

[Dovecot] bug in 99.13-rc2 in ldap md5 patch
by Farkas Levente 29 Dec '04

29 Dec '04

hi, it takes me another hour do debug it again, although i already report it for both joshua and timo. the original patch for openldap's md5 crypt has a small bug. in passdb-ldap.c the schema is already PLAIN-MD5 since that was set in the other part of the original patch in password-scheme.c. do anybody use dovecot with ldap and md5 password? i don't think so:-( this patch would be useful to apply before the final 0.99.13. anyway in the current 1.0 series the PLAIN-MD5 and LDAP-MD5 schema are different. at least plain_md5_verify and plain_md5_generate differ from ldap_md5_verify and ldap_md5_generate. why? -- Levente "Si vis pacem para bellum!" --- dovecot-0.99.13/src/auth/passdb-ldap.c.lfarkas 2004-12-22 17:06:25.000000000 +0100 +++ dovecot-0.99.13/src/auth/passdb-ldap.c 2004-12-22 17:06:56.000000000 +0100 @@ -109,12 +109,11 @@ } /* Special case for OpenLDAP's MD5 type */ - if (strcasecmp(scheme, "MD5") == 0) { + if (strcasecmp(scheme, "PLAIN-MD5") == 0) { buf = buffer_create_static(data_stack_pool, 16); if (base64_decode(password, strlen(password), NULL, buf) == 1 && buffer_get_used_size(buf) == 16) { password = binary_to_hex(buffer_get_data(buf, NULL), 16); - scheme = "PLAIN-MD5"; } }

[Dovecot] Deleting a message through IMAP
by Doug Eubanks 28 Dec '04

28 Dec '04

I have been having a problem with the test releases...I am now using Test 59. When I delete a message using SquirrelMail (IMAP) the message stays in the message list....but you can't open it anymore because it can't be found, if I logout and log back in...the message is gone from the list. I thought it could be a problem with the cache, so I added mail_never_cache_fields = MessagePart Envelope Body only to recieve Dec 24 09:23:34 news dovecot: IMAP(admin): mail_never_cache_fields: Invalid cache field name 'Body', ignoring Any ideas? This problem has plagued me for a while and I always go back to using the and older test like 22 and the problem isn't there... Doug

[Dovecot] Moving existing MD5 passwords to LDAP?
by Ben Beuchler 28 Dec '04

28 Dec '04

I have a dovecot installing working quite well for around 1000 users using passwd-file authentication. I'm moving to LDAP and would sure love to be able to migrate the existing MD5 passwords. I've tried using ldapmodify to set "userPassword" to {CRYPT}$1$H8JE0k5X$y.ptShgYbOgWF.99lX88N1 and {MD5}$1$H8JE0k5X$y.ptShgYbOgWF.99lX88N1 In both cases, ldapmodify exits without errors but I cannot bind using the new password. Any ideas? -Ben -- Ben Beuchler There is no spoon. insyte(a)emt-p.org -- The Matrix

[Dovecot] bidirectional synchronization of dovecot-managed maildirs
by James Leifer 28 Dec '04

28 Dec '04

Hello and happy holidays, I've been thinking about high performance bidirectional synchronizing the mail on my laptop (which is frequently disconnected) and my workstation at work (which is always on and receives all inbound mail). Both run dovecot on top of maildir. I've been playing with offlineimap, unison (which I already use for all my non-mail files), as well as the gnus agent (in IMAP "disconnected mode"). None of these solutions is really satisfactory: * offlineimap treats a message refile between folders as a delete-plus-resend; * unison doesn't understand the semantics of flag changes at the end of files in maildirs; it also has to stat all the files (which can become slow) to detect changes; * gnus agent can't refile messages between folders when in disconnected mode. Perhaps there are better disconnected IMAP modes available for other MUAs, but, it seems like a more general solution would be appropriate. In particular, the "uniq" field of a maildir filename is an easy way of tracking the identity of a message as it gets refiled. My question: would it be difficult to patch dovecot so that it maintained the *same* uniq when copying messages between folders? What about adding hooks that get triggered whenever dovecot copies or deletes messages? These hooks could log the changes. Later, when one tries to sync, one merges the changes from both replicas and then applies them. I'm aware that dovecot has an option to do copies as hardlinks, which is a good start, but still requires one to stat the files to discover which have the same inode. This is *much* slower than simply listing the directories and comparing maildir "uniq" fields. I'm aware that this invariant wouldn't be maintained if other programs modified the maildirs under dovecot's nose, but I'm willing to exclude this possibility. Suggestions? Best regards, -James Leifer

[Dovecot] dspam plugin
by Johannes Berg 27 Dec '04

27 Dec '04

The first version is available at http://johannes.sipsolutions.net/edit/Projects/dovecot-dspam-integration/co… I'm calling dspam for every message, that seemed easier for now. I will probably integrate Tom's idea about storing the messages until a cron-job picks them up at night by just storing signatures into mysql, in which case its easy to do with a single query: INSERT INTO new_spam (user, signature, isspam) VALUES (<user>, <signature>, <isspam>) ON DUPLICATE KEY UPDATE isspam = <isspam> with given values for <user>, <signature> and <isspam> and a key on (user, signature). For now, however, calling dspam for every message works good enough for me, and seems to work. Regards, Johannes

[Dovecot] Worthwile to use quotas?

I'm aware that dovecot doesn't support Maildir++ quotas yet (pity). However, is it still worthwhile to set up something like Postfix + Maildrop to use quotas, or is dovecot's lack of support just going to throw a wrench in the works? Thanks, :Peter

There's good reasons to use Maildir, and there's good reasons to stay with mbox, but avoiding /var/mail is not one of them. mbox is the "classical" format, and Timo (I assume) chose to setup dovecot to use the "classical" location scheme as well, which is to store incoming mail below /var/mail and let users pull it from there and store it however they want at their personal folder below /home. If you are new to all this, actually there is probably a good point in staying close to the "classical" way of doing things, so that you can get help from more sources. I suggest keep receiving mail below /var/mail as mbox files, and play around with mbox and Maildir storage for different (test-)users below /home.

[Dovecot] Mixing mbox and maildir

Is there some way to add a maildir folder to a mbox hierarchy? My folders are all mbox, but I want to migrate some client-side mail from a client (PMMail2000) that stores messages as individual files, and it might be easiest just to dump all the files into a maildir directory with suitable naming.

[Dovecot] moving messages with bash
by Todd Slater 22 Dec '04

22 Dec '04

I use bogofilter and a script or two to manage junk mail on my home box (fetchmail from POP3, postfix and procmail to local maildirs, mutt for MUA). Since these mails are just files I figured it never mattered that I moved them from one folder to another via a bash script, but some posts on this list make me think I shouldn't do that on a server running dovecot (IMAP). What I currently have is a MakeJunk folder (maildir) that I drop spam that was missed into, then a cron job runs mail in that folder through bogofilter and moves it to a Junk folder. Is it sane to do that with simple mv, or do I need to use some special imap command? Confused, Todd

[Dovecot] Stalled Authentication, Great Clues
by Richard Petty 21 Dec '04

21 Dec '04

I've just installed Dovecot 0.99.12.1 onto a White Box EL 3 server. I'm mostly following the email server setup instructions at http://www.wanderingbarque.com/mailserver.html and getting Dovecot to work is the last task to complete. I've compiled Dovecot with LDAP support. I'm authenticating Postfix via SASL to the LDAP database just fine, and I also authenticate and manipulate LDAP info from JAMM very well, too. However, Dovecot authentication seem to hang up when a correct password is submitted (POP or IMAP... it doesn't matter). Here's an example of the problem: [root@kayak /etc] telnet localhost 110 Trying 127.0.0.1... Connected to localhost.bramble.com (127.0.0.1).

As you can see, once I hit the return key to submit the password I do not get another prompt. In fact, Dovecot doesn't respond at all although it seems to respond to the escape character just fine.

Dovecot's log shows that it eventually times out the client, although the client never seems to get wind of this: pop3-login: Dec 19 22:13:08 Info: Disconnected: Inactivity [192.168.0.6] I know that Dovecot is connecting to the LDAP server because if I mess up the Dovecot LDAP password in the dovecot.conf file I get an authentication error (as I should): dovecot-auth: Dec 19 20:52:19 Error: LDAP: ldap_simple_bind_s() failed (dn cn=dovecot,dc=dillo,dc=info): Invalid credentials Again, if client submits an incorrect email account password everything works as it should: Dovecot tells the client that the password is incorrect, over and over, if necessary. However, if the password is entered correctly then Dovecot hangs up for good. --Richard

[Dovecot] Postfix + dovecot-auth
by Timo Sirainen 20 Dec '04

20 Dec '04

I wrote a patch to Postfix which now supports SMTP AUTH using dovecot-auth. This time it doesn't need any Dovecot libraries and it's backwards compatible with Cyrus SASL by default. You'll just need to set one variable in Postfix config file to enable it. Patches and instructions in: http://dovecot.org/patches/postfix/ Not very well tested yet though. And it doesn't work with 1.0-test59, you'll need to have at least today's nightly snapshot.

[Dovecot] Just delete that index
by Doug Luce 20 Dec '04

20 Dec '04

I get a few messages of this ilk each day: Dec 16 01:56:31 aurora dovecot: IMAP(doug): Corrupted index cache file /home/doug/Maildir/.users.joe/dovecot.index.cache: indexid changed I usually address this by deleting dovecot.* in the directory of issue. I was thinking that I could instead just have the server delete these files and attempt to recreate them, and skipping that error message unless the re-created files are also corrupted. Any problems with this approach? Thanks, Doug
