[Dovecot] Question about mail storage
by Stewart Dean 21 Apr '06

21 Apr '06

I am in the throes of trying to understand all the issues of transforming an old UW Imap server with mbox (I think) INBOX format running sendmail and procmail serving 3500 users to dovecot and maildir format. Currently, the folders are under ~/mail and the INBOXes are under /var/spool/mail. If I understand correctly, the typical default Dovecot/maildir format installation will have both the INBOX and folders (prefixed with a period), so they take the format: .<foldername>) under ~/Maildir. Right? I am planning to do a gradual phaseover of one chunk of ids at a time........ "I am in a maze of twisty tunnels, all alike. A dwarf runs by........" Some questions: 1) In the UW IMap docs, formats.txt discusses a bunch of different mailbox formats. I am unclear as to whether I currently have what Crispin describes at .unix format or .mbx format. > . unix This is the traditional UNIX mailbox format, in use for nearly > 30 years. It uses a line starting with "From " to indicate > start of message, and stores the message status inside the > RFC822 message header. > > unix is not particularly efficient; the entire mailbox file > must be read when the mailbox is open, and when reading message > texts it is necessary to convert the newline convention to > Internet standard CR LF form. unix preserves UIDs, and allows > the creation of keywords. > > Only one process may have a unix-format mailbox open > read/write at a time. > and ... > . mbx This is the current preferred mailbox format. It can be > handled quite efficiently by c-client, without the problems > that exist with unix and mmdf formats. Messages are stored > in Internet standard CR LF format. > > mbx permits shared access, including shared expunge. It > preserves UIDs, and allows the creation of keywords. How do I tell them apart? Alternately, how do I tell if what I now have (some sort of one big single-file INBOX) is mbox? Or is what he's referring to as unix just mbox 2) How to change Where Things End Up a) The users' ~/.procmailrc pretty much consists of: MAILDIR=$HOME/mail Am I correct in assuming that this should be changed to: MAILDIR=$HOME/Maildir/ ? b) Mail appears to end up in /var/spool/mail/<username> because that's the procmail default (ORGMAIL). To redirect individual users (because this will be a gradual changeover), am I correct in assuming that putting: DEFAULT=$HOME/Maildir/ in ~/.procmailrc will redirect incoming mail? 3) I see that, in the default configuration, /everything/ will now be under ~/Maildir and thus in the home directories. Is there a reason to get away from a separate INBOX directory (we use /var/spool/mail)? I'd have to rebuild the homedir filesystems to accommodate the INBOX demands. This isn't all that big a deal, I'd like to understand the rationale..or should I just bow to the inevitable? 4) Pardon my stupidity, but how is the Dovecot INBOX under maildir++ organized? a) Is it a separate directory under ~/Maildir (say ~/Maildir/INBOX or some such) that has a separate file for each message or b) are the INBOX messages just mixed in with the folders under ~/Maildir. If so, how are they differentated? Enlighten my ignorance,.please! I've been reading docs today until my brain feels like custard, but I couldn't seem to get clear definitive answers to these questions........ Thanks in advance. -- ==== 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] How to configure virtual use suport.
by Slawomir Orlowski (Cympak) 21 Apr '06

21 Apr '06

Hello, I have RHEL v4 Linux. I have always been using exim with teapop (po3 client) for my emails. I would like to try dovecot (imap) because I would like to implement squirrelmail. I'm hosting several domains with email each on different IP. I have the some user names in different domains with my pop3 teapop. Can I have it with dovecot. I managed to configure exim to deliver messages for localuser to Maildir directory. directory = /var/spool/mail/${local_part}/Maildir and for virtual_users to Maildir directory. directory = /var/spool/mail/${domain}/${local_part}/Maildir This is working. Email are delivered. But I cannot to connect with my Outlook Express to imap server and download them. I cannot see how dovecot would differentiate between users with the some named in different domains. I believe that me configurations is not right. I would like for starters to have real user to be checked (like in teapop) against /etc/password /etc/shadow file, and virtual user against /etc/mail/passwd.domain file which would contain login:passwd pairs. Do I need like with teapop different IP for every domain ? How do I do that? Any advice would be appreciated. I'm going for a few days vacation I hope that somebody will be able to give me some hints. I have attached my dovecot.conf file. regards Slawomir Orlowski

[Dovecot] INBOX as mbox, other mailboxes as maildir
by Paul de Weerd 21 Apr '06

21 Apr '06

All, I'm trying to teach dovecot to use the mbox format for /var/mail/%u and maildir for /home/%u/Mail/ but I'm having quite a hard time. This is Dovecot v1.0.beta3 under OpenBSD 3.9 on sparc64. I've been fiddling with default_mail_env and also tried separate namespaces, but all to no avail. Here's some of the things I tried : default_mail_env = maildir:/home/%u/Maildir:INBOX=mbox:/var/mail/%u ... default_mail_env = INBOX=mbox:/var/mail/%u:MAIL=maildir:/home/%u/Maildir/ ... namespace private { separator = / prefix = inbox = yes location = mbox:/var/mail/%u } namespace private { separator = / prefix = "Folders/" location = maildir:/home/%u/Mail } ... But all it does is complain that my mbox files dont have a cur/ directory in them or create mbox-type files in /home/%u/mail/, in stead of saving my mail in a maildir under /home/%u/Mail/. So using namespaces doesn't seem to be such a good idea after all, I can have extra maildirs under Folders/ in ~/Mail, but that's not where my IMAP client saves its sent mail. I'm quite obviously doing something wrong, is this possible at all ? What is the correct incantation for the default_mail_env setting for such a setup ? Any clues would be greatly appreciated, Cheers, Paul 'WEiRD' de Weerd -- >++++++++[<++++++++++>-]<+++++++.>+++[<------>-]<.>+++[<+ +++++++++++>-]<.>++[<------------>-]<+.--------------.[-] http://www.weirdnet.nl/

[Dovecot] multiple domains for the same user
by pyroneus 21 Apr '06

21 Apr '06

I have postfix and dovecot set up to use virtual domains. I am now experiencing a problem that when I log in as user1(a)domain1.tld and then log in as user1(a)domain2.tld all the emails are downloaded for user1(a)domain2.tld as it thinks all the messages are new. is there anyway to stop dovecot from saying that all the messages are new?

[Dovecot] dovecot.rawlog for imap-login
by Jared 21 Apr '06

21 Apr '06

I'm trying to see what users are sending for login. I added the rawlog binary in front of the imap-login in the config file. I'm not seeing any rawlogs. I added the dovecot.rawlog in the dovecot user directory (since that's what the imap-login process seems to run as) and it's permission are wide open. Still nothing. Help?

[Dovecot] Very Complex Master Password Challenge
by Marc Perkel 21 Apr '06

21 Apr '06

This might require adding some new code to Dovecot to pull this off. But it would be extremely powerful if I could get this to work. Here's the situation. Having a master password is great for helping users and doing tech support. But - suppose I'm hosting many domains and I want to create master passwords for each domain separately so that the owners of the domain can log in as any user within that domain? Here's the way I have things set up. I have a directory of passwd/shadow pairs for each domain as follows: /etc/vmail/passwd.domain1.com /etc/vmail/shadow.domain1.com /etc/vmail/passwd.domain2.com /etc/vmail/shadow.domain2.com Additionally I have a master domain used for management of the other domains. The master domain is an email account for each domain under the domain junkemailfilter.net. domain1.com(a)junkemailfilter.net domain2.com(a)junkemailfilter.net The password and shadow files are like the others: /etc/vmail/passwd.junkemailfilter.net /etc/vmail/shadow.junkemailfilter.net So - the idea is that the owners of the domain have access to the email accounts on junkemailfilter.net and what I'm hoping to do is that they can use this as the master password for their domain only. Example: domain1.com(a)junkemailfilter.net domain2.com(a)junkemailfilter.net I suppose that the master password feature needs another new feature to limit the scope of what it is allowed to be a master password for. Something perhaps like: passdb passwd-file { # Path for passwd-file args = /etc/vmail/shadow.junkemailfilter.net master = yes scope = *@%u } In the above example "%u" is the user part of the master password. So that that master user would be for example "domain1.com(a)junkemailfilter.net" and it would be the master password only for users of domain1.com and not domain2.com. So - if you can follow this - then you will see that this would be a really cool feature to have. And - I'm guessing that it might be easy to implement.

Hi all. I got my previous problem fixed. Effective uid and gid fix in dovecot.conf file made it work. However, I'm still seeing this in my /var/log/dovecot.conf dovecot: 2006-04-13 21:09:00 Info: imap(chl(a)iaminla.com): Effective uid=1000, gid=1000 The uid and gid *should* both be 1009, and I can't for the life of me figure out how to configure that.

[Dovecot] hard link between courierimapuiddb and dovecot-uidlist?
by Jeff Tucker 21 Apr '06

21 Apr '06

Hi, guys. I'm attempting to transition between Courier IMAP and Dovecot. I may not be able to transition all the courierimapuiddb files instantly or even transition all my servers at the same time. Ideally, it wouldn't matter. Users can login and get to a Courier IMAP machine or a Dovecot machine and read their email (all mounted via NFS). My question is: is there any reason I can't just do a hard link between courierimapuiddb and dovecot-uidlist? That way, I can transition users over to Dovecot at my leisure. And, if I need to, I can move back to Courier. The hard link is essentially free and lets me make sure these files stay synced. Thanks Jeff

[Dovecot] UIDL documentation
by Mark E. Mallett 21 Apr '06

21 Apr '06

Hi, I see this in the 1.0-beta7 dovecot-example.conf file: # If you want UIDL compatibility with other POP3 servers, use: # UW's ipop3d : %08Xv%08Xu # Courier version 0 : %f # Courier version 1 : %u # Courier version 2 : %v-%u # Cyrus (<= 2.1.3) : %u # Cyrus (>= 2.1.4) : %v.%u # Older Dovecots : %v.%u # # 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. and on the wiki at http://wiki.dovecot.org/Migration there is this: By default Dovecot generates POP3 UIDs differently than UW-IMAP. If you want to preserve them, with 0.99.x you'll have to patch Dovecot. With 1.0-tests you can use: pop3_uidl_format = %08Xv%08Xu In the dovecot-example.conf file, it appears that the mentions of "%08Xu%08Xv" as being fail-safe and being the new default may be typos, since that format doesn't seem to come from anywhere. Should they not say "%08Xv%08Xu" ? (It'll still provide the same sort of unique value, only with the ends reversed; i.e. it should still work ok. But consistency and compatibility is nice.) mm

[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

Hello everybody! I was searching around for an solution of my problem what surely is just a little thing, but nothing helped me out. Here the error in the mail.log: pop3(contact(a)maddy.cc): Failed to create storage with data: /var/vmail/maddy.cc/contact/ pop3-login: Login: contact(a)maddy.cc [84.4.228.150] dovecot: child 30083 (pop3) returned error 89 Who has to be the owner/group for /var/vmail/maddy.cc and /contact ?

[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] Feature request for pop3

Dear List, is it possible to integrate a function for timelimits the pop3-connects? I require this function for an email-masshosting-project. My problem is, the most customers will lookup all 30 seconds or 1 minutes for new mails, that is stupid so I mean. My idea is a function where the customer must wait (for example) 3 minutes for a pop3-connect and lookup for new emails. Is it possible? Thx for your help and for the very good software best regards, Sascha

[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.

[Dovecot] dspam plugin
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

[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] Postfix dovecot SASL and LDAP not working...

[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

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.

[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 prefers GNUTLS if it's found, but fallbacks to OpenSSL. If you wish to force using OpenSSL, give --with-ssl=openssl to configure." Kind regards Kristoffer

[Dovecot] dovecot won't compile for GnuTLS
by Kristoffer Bylund 10 Apr '06

10 Apr '06

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] 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

[Dovecot] TCP wrappers patch
by Timo Sirainen 09 Apr '06

09 Apr '06

I finally started looking into how to use libwrap, and even got the code working: http://dovecot.org/patches/1.0/tcp-wrappers.patch However once everything was done, I realized it can't work that way because login processes are normally chrooted. So if you want TCP wrappers and don't care that much about the security given by chrooting, you could disable it and use the above patch. Alternatively you could just make sure that the hosts.allow/deny files are always copied inside the chroot. I think I'll just forget about TCP wrappers for now, and implement it in Dovecot 2.0 as some separate non-chrooted process.
