19 Apr '06

Hi, i'm having a weird message connecting to an account using IMAP + TLS from thunderbird (evolution works great, so does SSL in thunderbird, haven't tested anywhere else yet): "You cannot login to <domain> because the server has disabled login. You may need to connect via SSL or TLS. Please check..." in auth.log all i have is: "imap-login: Aborted login: rip=<my ip>, lip=<server ip> Any thoughts? -- João Inácio http://www.jcinacio.com

[patch] Re: [Dovecot] Test migration (IMAP copy) and INTERNALDATE?]
by Apps Lists 19 Apr '06

I haven't been able to find what is responsible for altering the time on APPENDed mail, but was able to come up with a temporary workaround ... simply calling utime() later on in the process resolves it.

[Dovecot] Does NIS/yp work for authentication
by Stewart Dean 19 Apr '06

19 Apr '06

If a host is running NIS (passwd file ends in +::0:0:::) authentication, will dovecot be able to authenticate with auth_userdb = passwd directly and automagically or do you have to do a ypcat passwd > pwfile periodically to generate a passwd file that dovecot can use? ?

[Dovecot] LDA Plugin Maybe?
by Timothy White 19 Apr '06

19 Apr '06

I was just looking into setting up DSPAM, with the Dovecot LDA. Essentially, what I was probably going to do, was use DSPAM as the Delivery agent, after postfix, and then have it pass it off to dovecot, or something along those lines. I just had an idea, if we start using libdspam, in the dspam plugin, or one of the other suggested methods, we could have a similar plugin in the LDA, so that if it's marked as spam, deliver it straight into the Spam folder! Also, with Sieve, can we make it create a folder if the folder doesn't exist, and can it modify the subscriptions file? Thanks Tim -- Linux Counter user #273956

Because i have the user 'virtual' who manages the maildirs and the accounts (via PostgreSQL) and the user dovecot, but i tried already different scenarios with both and still no success.

[Dovecot] unofficial Survey about your Dovecot server :) to compare with my own server setup...
by Flavio Domingos 18 Apr '06

18 Apr '06

Hi Borthers/Sisters Thanks for all the developer(s) and for all the hard work spent on build this great piece of software! I loved Dovecot since it is really easy to set up and really fast but I am really new to it (only 2 weeks and half). Right now, our server configuration is: Server: Apple Xserve G5 dual RAM: 4GB Number of Users: ~ 150 IMAP only users Authentication: LDAP Mailboxes sizes: ~200GB Dovecot version: 1.0 Beta 5 (I am looking forward to beta 7 that was released today) Email client software: mostly Thunderbird 1.5 Right now, we are experiencing occasional problem with imap users unable to connect to the server. With beta 3, we had to restart the dovecot/imap processes almost every 3 hours. with Dovecot beta5 we still have to restart the processes but it seems to occur every 3 days (Friday and Yesterday) and only in a peak time (around 3pm). I am waiting to occur it again and I will be able to grab more information about the number of processes, users, virtual memory, etc, etc. So, at this point, I don't have much information to debug the problem. Let's wait. I guess we have here a nice machine (xserve) and not a huge number of users (~150). So, I would expect that our server would handle the load. But having to restart Dovecot once a while, as I described, is not an option (users are getting frustrated). :( Maybe with Beta 7 with the feature "Added shutdown_clients setting to control if existing imap/pop3 processes should be killed when master is" can stop our nightmares :) By the way, our dovecot.conf is basically the default sent with the software. We haven't changed much there! Meanwhile, I'd like to know, if possible, whar are you using to run Dovecot like hardware, OS version, number of users and problems that you are experiencing. I'd like to compare with my setup and if it is the case, migrate to pure Linux or FreeBSD if it is more stable than OS/X! Best Regards, Flavio Domingos - San Francisco/CA -

[Dovecot] 1.0.beta6 released
by Timo Sirainen 14 Apr '06

14 Apr '06

Fixes, mostly: * The login and master usernames were reversed when using master_user_separator (now the order is UW-IMAP compatible). * Killing dovecot master process now kills all IMAP and POP3 processes also. + -a parameter to dovecot prints now all settings that Dovecot uses. -n prints all settings that are different from defaults. + Added pop3_lock_session setting + %M modifier returns string's MD5 sum. Patch by Ben Winslow - PLAIN SASL authentication wasn't working properly, causing failed logins with some clients (broken in beta4) - Fixes to Maildir++ quota, should actually work now - Don't crash if passwd-file has entries without passwords (eg. deny=yes databases) - Fixed prefetch userdb to work nicely with other userdbs - If master process runs out of file descriptors, don't go to infinite loop (unlikely to have happened unless the OS's default fd limit was too low) - Fixed non-plaintext password lookups from LDAP. Patch by Lior Okman - %U modifier was actually lowercasing the string. Patch by Ben Winslow

[Dovecot] Compile issues dovecot-1.0.beta7
by Mark E. Mallett 14 Apr '06

14 Apr '06

Hi, I haven't tried compiling 1.0 series since -test52, figured I'd give it a shot. There were a couple of minor problems. This is building on a fairly ancient BSD/OS box, so the issues may not be universal, but I suspect these ones are. ==================== Building in src/lib-dict/dict.c : loading the 'dict' program fails because it can't find various RAND and other functions. Adding -lcrypto fixes. I did this by hand rather than adjusting the configure script; looks like the need for -lcrypto is detected in other cases, but not here. ==================== In src/plugins/quota/quota-fs.c , line 276: #ifdef HAVE_QUOTACTL if (quotactl(QCMD(Q_GETQUOTA, USRQUOTA), root->mount->device_path, root->uid, (void *)&dqblk) < 0) { I believe the first two arguments are backwards, i.e., should be: if (quotactl(root->mount->device_path, QCMD(Q_GETQUOTA, USRQUOTA), root->uid, (void *)&dqblk) < 0) { I have a vague recollection of seeing this already being reported, but can't instantly find it, so what the hey. ==================== Yours, -mm-

[Dovecot] 1.0.beta7
by Timo Sirainen 13 Apr '06

13 Apr '06

Sorry, the authentication problem still wasn't actually fixed in beta6. Now, this time I tested every possible authentication case that it really works. I'll soon create a CVS branch which is going to stabilize into the 1.0 release. I won't add new features there so it shouldn't really get broken anymore, at least because of new features.. So, two changes in this release: + Added shutdown_clients setting to control if existing imap/pop3 processes should be killed when master is. - Master login fixes, PLAIN authentication was still broken..

[Dovecot] problem with out-of-box fedora rpm
by Marc Newman 13 Apr '06

13 Apr '06

Hi Folks, Most of the available howtos suggest that an out of the box binary rpm should at least be able to start on a similarly out of the box Fedora Core 4 installation. However, whenever I run /sbin/service dovecot start I get a failed message. Dovecot was installed using the standard package that ships with FC4 (i386 0.99.14). The only slightly anomalous feature of my system is that wlan0 not eth0 is the primary network interface. This hasn't upset anything else though. I even tried disabling the firewall briefly to see if that had any effect, and it doesn't. So, two questions. Firstly, any ideas on why it might be failing to start? Secondly, where might I look (like, which logs/where) for clues? /var/log/messages doesn't contain any references to dovecot (I grepped it), so I'm out of ideas. My sendmail configuration is working perfectly, and I can send and receive emails fine. But I need pop3 access for some of my users. Just to recap, I haven't even got to the point of testing whether its listening, or configuring authentication. It will not start out of the box. Am I missing some essential configuration step? Marc.

by Ryan Kolak 13 Apr '06

13 Apr '06

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hey everyone.. been struggling with building a mailserver and i'm almost done. One of the last pieces is integrating dovecot with dspam so that I'm users can train their spam filters easily (sieve filtering is the last piece left.. that should be interesting.. lol) Anyway, I think i found an issue with memory allocation, and I'm not sure if its due to changes to the code base or if its a 64 bit memory issue. When i try to move a message into or out of the spam folder, it fails, and with debugging on, there are strange entries in the syslog. Added a few more debugging statements, and I get the following showing up: Apr 11 00:04:41 uberserver imap: found signature 443b336a271581061887518 Apr 11 00:04:41 uberserver imap: working with signature (<E4>Z Apr 11 00:04:41 uberserver imap: in call dspam Apr 11 00:04:41 uberserver imap: /usr/bin/dspam --source=error --stdout - --class=spam --signature=(<E4>Z Apr 11 00:04:41 uberserver dspam[1361]: Unable to determine the destination user Apr 11 00:04:41 uberserver dspam[1361]: DSPAM agent misconfigured: aborting The line with the correct signature showing up is simply outputing 'signature' after: signature = mail_get_first_header(mail, SIGHEADERLINE); The 'working with signature' that shows the corrupted signature is right before call_dspam is called, and it outputs siglist->sig: ... syslog(LOG_INFO, "working with signature %s ", siglist->sig ); if ((*enh_error = call_dspam (siglist->sig, is_spam))) { ... This leads me to believe that there's a problem with: list_append(listpool, &siglist)->sig = p_strdup(listpool, signature); but I'm really not sure how dovecot deals with allocating pooled memory, as that's what it appears to be doing. I'm not sure what information might be useful to anyone in helping me look into this and the searches i've been able to do have been unsuccessful.

[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

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?

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.

[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.

[Dovecot] Postfix dovecot SASL and LDAP not working...
by Brice Figureau 12 Apr '06

Hi, I'm trying to setup a new mail server where postfix 2.3-20060405 would use Dovecot's SASL and users located in LDAP. It's with dovecot-1.0-beta5. On the postfix side, I followed the SASL_README and have the following in main.cf: smtpd_sasl_type = dovecot smtpd_sasl_path = private/auth smtpd_sasl_auth_enable = yes On the dovecot side I have the following related to auth: auth_verbose = yes auth_debug = yes auth_debug_passwords = yes auth default { mechanisms = plain digest-md5 cram-md5 # LDAP database passdb ldap { # Path for LDAP configuration file, see /etc/dovecot/dovecot-ldap.conf for # example args = /etc/dovecot/dovecot-ldap.conf } # LDAP database userdb ldap { # Path for LDAP configuration file, see /etc/dovecot/dovecot-ldap.conf for # example args = /etc/dovecot/dovecot-ldap.conf } userdb prefetch { } user = root ## ## dovecot-lda & postfix SASL specific settings ## socket listen { master { path = /var/run/dovecot-auth-master mode = 0666 } client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } pop or imap authentification with LDAP works fine: Apr 11 17:43:08 localhost dovecot: auth(default): client in: AUTH^I1^IPLAIN^Iservice=IMAP^Isecured^Ilip=127.0.0.1^Irip=127.0.0.1^Iresp=AGJyaWNlAHRvdG8= Apr 11 17:43:08 localhost dovecot: auth(default): ldap(raymond,127.0.0.1): base=ou=people, dc=daysofwonder, dc=com scope=subtree filter=(&(objectClass=CourierMailAccount)(uid=raymond)) fields=uid,userPassword,homeDirectory,uidNumber,gidNumber,mailbox Apr 11 17:43:08 localhost dovecot: auth(default): ldap(raymond,127.0.0.1): uid(user)=raymond userPassword(password)={PLAIN}toto homeDirectory(userdb_home)=/home/raymond uidNumber(userdb_uid)=1000 gidNumber(userdb_gid)=1000 mailbox(userdb_mail)=/home/raymond/Maildir Apr 11 17:43:08 localhost dovecot: auth(default): client out: OK^I1^Iuser=raymond^I Apr 11 17:43:08 localhost dovecot: auth(default): master in: REQUEST^I1^I15439^I1 Apr 11 17:43:08 localhost dovecot: auth(default): ldap(raymond,127.0.0.1): base=ou=people, dc=daysofwonder, dc=com scope=subtree filter=(&(objectClass=CourierMailAccount)(uid=raymond)) fields=homeDirectory,uidNumber,gidNumber,uid,mailbox Apr 11 17:43:08 localhost dovecot: auth(default): master out: USER^I1^Iraymond^Isystem_user=raymond^Ihome=/home/raymond^Iuid=1000^Igid=1000^Imail=/home/raymond/Maildir Apr 11 17:43:08 localhost dovecot: imap-login: Login: user=<raymond>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured postfix SASL doesn't work, but more important don't print any debug messages, nor try to contact the LDAP server at all: Apr 11 18:00:59 localhost postfix/smtpd[15637]: connect from localhost.localdomain[127.0.0.1] Apr 11 18:01:13 localhost dovecot: auth(default): client in: AUTH^I3^Iplain^Iservice=smtp^Iresp=YnJpY2UAYnJpY2UAdG90bw== Apr 11 18:01:14 localhost dovecot: auth(default): client out: FAIL^I3^Iuser=raymond Apr 11 18:01:14 localhost postfix/smtpd[15637]: warning: localhost.localdomain[127.0.0.1]: SASL plain authentication failed: I tried several variations of the config, like without userdb prefetch, moving postfix socket config block in another auth block... Nothing worked. Since the samples are mentioning only pam as userdb and passdb source, maybe it can't work with LDAP ? Any idea on how to solve this issue ? Thanks, Regards, -- Brice Figureau
