[Dovecot] Suggested patch: retain user's group privileges after logging into IMAP
by Lior Okman 11 Mar '06

11 Mar '06

Hi, I'm attaching a suggested patch that lets an authenticated user access shared IMAP folders even if the user doesn't directly own the storage, but is a part of a group that has permissions on the storage. This allows for the administrator to setup a shared mailbox with permissions given to a group instead of a user, and allow all of the users that belong to the group to access the mail according to the file-system permissions. What do you think? Is this the right way to do this, or am I missing something security-wise? I'm also attaching a bug fix for the LDAP passdb, where if the password scheme wasn't PLAIN, the password would be cleared from memory before being used to authenticate the user, and the authentication would fail. Regards, Lior

[Dovecot] Segfault problem when using TWO dovecot servers!
by Adam M. Dunn 10 Mar '06

10 Mar '06

Forgive me if this gets submitted twice. I had issues signing up for the listserv but I think I'm strait now. Hi all, I just started working with Dovecot and I'd like to use it for my organization, but I've run into a little problem. So far I love it and it does what I need. One thing we need is to be able to write to multiple mailbox formats on a per user basis (mbox or Maildir), and it does just that. I want users to be able to choose their format, and I can let it autodetect for me. The way I do that is I have Maildrop filters check for the presence of a ~Maildir, and if it finds that it writes to it, otherwise it writes to ~mbox. Dovecot is the only IMAP server I've found to read either or without hard coding one or the other in the config file. The problem: We also want failover. Mail/home directories are NFS mounted. I was planning to setup two dovecot servers, and noticed that whenever one server writes its temp files to the mail directory, if another server tries to read it you get a segfault and the child process fails and dies. So it basically looks like only one server can own the files, and it won't share. I considered trying to set the INDEX option on the mail boxes to write local indexes, but if I try to specify something like: default_mail_env = INDEX=/var/indexes/%d/%n, it doesn't work. Sure I can make it work by putting in a mailbox format before the INDEX, but then I can't use the autodetect which I need. Here's the syslog error: kernel: imap[13689]: segfault at 00007fffffe38000 rip 00002aaaaad3823f rsp 00007fffffe351f0 error 4 Any solutions? I really need this to work badly, or we may have to rethink our entire mail strategy. I'm also using the latest version 1.0beta3. I considered namespaces, but correct me if I'm wrong, you can't setup two namespaces and have it pick the first mailbox format available like the autodetect feature does. I tried seting up namespaces for both mbox and Maildir, but it just creates both. Please help someone. I need a solution to present to my boss, even if that means we have to run one server until the bug is fixed in the next version. Thanks, Adam

[Dovecot] POP3 extension to accept UIDL ranges?
by Matthias Andree 10 Mar '06

10 Mar '06

Greetings, is anybody aware of an extension to POP3 that supports UIDL ranges? It would be very useful for keep-messages-on-server setups (yes, I know, IMAP4 domain) to be able to do UIDL 21-42 to obtain just these 22 UIDs (this would always have to be a multi-line reply, just like UIDL without argument). If such a thing does not exist yet, perhaps a keyword such as "[X]UIDLRANGES" in the CAPA response might advertise this feature to clients. Regards, -- Matthias Andree

[Dovecot] Two namespaces with same prefix.
by Václav Haisman 09 Mar '06

09 Mar '06

Hi, I have yet another problem. First let me explain my setup. I used to use pine a lot so there are mbox mailboxes in ~/mail. Recently I added a Maildir too and moved most of the mbox mailboxes into Maildir format. Now I thoght it would be nice to have them all "in line" in Thunderbird so I tried this configuration: namespace private { separator = / prefix = location = %h/mbox inbox = yes } namespace private { separator = / prefix = location = maildir:%h/Maildir } The problem is that with this configuration I cannot access the ~/mail/box mailboxes. Thunderbird responds with "Mailbox doesn't exist: box" Is such kind of configuration with two namespaces having same prefix unsupported? Vaclav Haisman

[Dovecot] Dovecot + FreeBSD 6.0 + pam_ldap + nss_ldap

Hello all I am new to dovecot and I have some troubles to make it working on a FreeBSD 6.0 box On this machine I have nss_ldap + pam_ldap working to login users but dovecot is not working for "ldap" users, it works only for users that are "really" in /etc/passwd file. I have configured dovecot to use the passwd auth mechanism as the OS is suppose to do the job, but it won't work. See attached my dovecot.conf file. Thanks for any help. -- Regards Frank Bonnet

[Dovecot] Default SELinux policy on Fedora FC4 prevents dovecot service from starting
by slohcine＠verizon.net 09 Mar '06

09 Mar '06

Hello, I recently setup a Fedora FC4 server to host e-mail and webapps. During the install, I turned on SELinux in active mode. All apps seems to work OK but Dovecot daemon won't start. In the audit log, I see this entry when I try to start the dovecot daemon. type=AVC msg=audit(1141464818.541:40305): avc: denied { read } for pid=1989 comm="dovecot" name=dovecot.pem dev=md2 ino=3646976 scontext=system_u:system_r:dovecot_t tcontext=system_u:object_r:cert_t tclass=file type=PATH msg=audit(1141499436.214:3266533): item=0 name="/etc/pki/dovecot/dovecot.pem" inode=3646976 dev=09:02 mode=0100600 ouid=0 ogid=0 rdev=00:00 I put SELinux into permissive mode and Dovecot works OK. Looks like dovecot does not assume the correct security context when it initializes and reads the cert file. My question for the list is what changes should I make to the SELinux policy to safely permit dovecot to read the file? I'm no expert at SELinux but hoping for some direction, or another way to solve this problem. Ideally, I'd like to keep SELinux in enforcing mode. Many thanks, Eric

[Dovecot] MySQL problem when using Dovecot as proxy
by Christian Jensen 09 Mar '06

09 Mar '06

Hi, I have just installed Dovecot as a POP3 proxy with great success. Its works flawlessly when i keep to the standard but since I am proxying a Microsoft Exchange 2003 (because the build-in POP3 in MS sux bigtime) I would very much like to use account names like: DOMAIN\username and this doesn't work when I include that in the MySQL table. In the logfile it clearly writes DOMAIN\username so its some kind of translation between dovecot and MYSQL. Any suggestions. I another solution would be to allow all users instead of having to create them in the MySQL table. Is this possible ? /Christian P.S Before Dovecot some Outlook users could only download max. 250kB through POP3 - now with Dovecot there is NO LIMIT! :)

[Dovecot] :INDEX and :CONTROL in 0.99.14

Before anyone say "upgrade" for various reasons I can't right now (and at any rate everything else works well with this version). My problem is that I can't get :INDEX and :CONTROL working at all: default_mail_env = maildir:~/:INDEX=/home/dovecot/index/%d/% n:CONTROL=/home/dovecot/control/%d/%n ls -l /home/dovecot/ total 8 drwxrwxrwx 3 dovecot dovecot 4096 Mar 8 07:52 control drwxrwxrwx 3 dovecot dovecot 4096 Mar 8 07:55 index (I've made everything 777 for testing) The error I get is: Mar 8 09:54:26 host imap(user(a)domain.com): mkdir (/home/dovecot/index/domain.com/user/.INBOX) failed: Permission denied If I su to the user(a)domain.com user I can manually create the directory OK. I'm using LDAP for authentication if that makes any difference. Any clues? Pointers? Need more information? -- Karl Latiss <karl.latiss(a)atvert.com.au> Atvert Systems

[Dovecot] Can I install in the following fashion?
by Stewart Dean 08 Mar '06

08 Mar '06

<permit me my perhaps foolish preference...an explanation> I run mail service for a small college. I've long joked that if someone stole the mail server, the phone would ring before the alarm (which has a 1 minute delay) did, that the user base expected 25x8x367 coverage. Making updates/upgrades to the mail server feels like a tightrope walk with no net. I always appreciated UofWIMAP because there is one binary. Doing and upgrade or backing it out is simplicity itself. I could compile the single binary on my compile machine, test the same binary on my testbed, and then drop it in my production machine and it would work with a minimum of surprises. So portable, so predictable, no security risk of a compiler on a production machine. Of course, /most/ of open source software has all these bits and pieces scattered everywhere. Oh, it may install initially just dandy, but come the day when It's Time For The Upgrade.... 1) can I do it quick and clean and 2) can I recover to what I had before quickly and correctly if the upgrade flops?????? Alas, Dovecot is sprinkled in many, many pieces...but at least, I think (right?) that they are all in the prefix-dir. Gulp. So. I am hoping I can do this: Build/Test Install 1) build/install in /usr/local/dovecot_bld/ Build### in the expectation that everything will be stuck down there. I don't want to put it into /usr/local/ because it will be in there with everything else....no way to get just the dovecot stuff.. 2) tar up the contents of my prefix directory and extract it over on my testbed under /usr/local/dovecot. Notice that the path to dovecot's "stuff" has changed from /usr/local/dovecot_bld/ Build### to /usr/local/dovecot I'm hoping that this won't be a problem. I will point the line in inetd at it and Everything Will Work. 3) Assuming I don't change anything and everything tests out (flawlessly!), I............. Introduction to Production (assuming that all the mailboxes, homedirs and the like have been sorted out) 1) make a tarball of the current working dovecot executables dir (/usr/local/dovecot) 2) extract the tarball there as before on the testbed machine and everything is fine. 2) if the update flops, I can bring back the tarball of the previous Dovecot incarnation My Questions: A) Will this work or are there dependencies I'm not aware of? B) Is there Some Better Way or..... I have this ongoing <ahem> discussion with the Open Source wonks that delight in many, many modules, libraries, etc. I /know/ the reasons a developer would want to do things that way, but, for those of use fielding the application, it's /so/ much easier and success/failure recovery is /so/ much more likely if....there are only one or two or three chunks that we can drop in or quickly back out. I realize that the developer is coding in large part for the utter joy of creating a wondrous, living, breathing edifice of code, that works, that works cleanly, that works as none has before. Yes. But I would think (IMHO) that the developer would receive a greater portion of the ego rush (also a big part of the developer stimulus) of overwhelming application acceptance (and thunderous applause), if he or she made it easy to support and upgrade! You see a sysadmin is so often an utter coward (I confess), who doesn't like unpleasant surprises, whose managment Really Doesn't Like Unpleasant Surprises. When I do my job really well, nobody knows I've done anything. OK...let me have it. -- ==== 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] Busy studying
by Timo Sirainen 08 Mar '06

08 Mar '06

In case you're wondering why I haven't answered your mail. I try to do as much reading to exams as possible, and as little as possible anything else.. They're over in 2,5 weeks, so I'll start reading the old emails again then. :) BTW. If someone wants to help a bit, outlook-idle workaround seems to be broken. The timeout function never gets called in cmd-idle.c. I'm guessing it broke after I added the other timeout function for printing "OK Still here" message every 2 minutes, so the bug is probably in timeout handling in ioloop.c.

[Dovecot] Simple Question
by Charlie Davis 08 Mar '06

08 Mar '06

Brand spanking new to Dovecot. Trying to move over to it, got a few simple questions. 1) Is there any documentation on the .customflags file? Not sure what this is for... 2) I'd like to make a directory for every user NOT be writable. Meaning the email server (Exim) can put the mail down in the directory but a user can no move an email into it through Imap. I couldn't find a search for the mailing list either, so sorry if this has been asked 92380498 times. -Charlie

[Dovecot] Dovecot with mbox and maildir
by Dario Ale 08 Mar '06

08 Mar '06

Hello, I have a question, i need migrate from old mail server to new mail server, the mailboxes format in the new mail server is maildir, in the old is mbox, the problem is that only the INBOXs are approximately 64Gb (are 7000 users), in the new I installed Dovecot, in the old is UW-Imap. The question is, Is there any form for have mbox and maildir simultaneously with Dovecot? I am using Postfix, my MDA is procmail, this write mailbox in the correct format, then i can copy all INBOXs and HOMEs to the new mail server, and change the mailbox format "slowly", supposedly procmail detecting the mailbox format and Dovecot could detect too. Thanks, very much. pd: sorry, my english not is good. -- Dario Ale (dario.a en telpin.com.ar) Area Internet Telpin - Jason 1026 - Pinamar (7167) www.telpin.com.ar

[Dovecot] self-signed certificates
by Benjamin 08 Mar '06

08 Mar '06

Hallo, i'm having troubles installing self-signed certificates for dovecot. After installing, dovecot generates a key and cert. But he is using the wrong common name (where does dovecot get this name from?). I tried deleting them and installing a handcrafted cert with this: openssl genrsa -out mail.key 2048 openssl req -new -key mail.key -out mail.csr openssl x509 -req -days 4312 -in mail.csr -out mail.cert -signkey mail.key after that i tried to update the dovecont.conf to point to the new files. But dovecot refuses to read them, i allways get an error, that dovecot can't read the certificate file. With dpkg-reconfigure dovecot-common, dovecot generates new ones, and they are working fine, but have the wrong common name. Thanks in advance Regards Benjamin

Will that be a problem? I'm not sure, but I think this setting is used for compile time - it's where dovecot expects to find include files, it doesn't mean that anything will be installed there. If you're really concerned, then use "make -n install", and go over the commands that make would have run, you will be able to see exactly where everything goes. Or you could run "make install" inside a chroot jail. I also seem to recall that I saw a script somewhere that could trace the "make install" procedure and print exactly where it puts everything. It was being used for converting .tar.gz "make-based-installations" to rpms. > Q2: Will dovecot not be able to find system resources it needs? Dovecot should be able to find everything it needs, assuming the configuration files are ok. > Tar'ing up a directory is doable. RPM'ing hundreds of files scattered > here and there, perhaps referenced by others, perhaps with new > additions/deletions you don't know about sounds like an heroic task. Tar`ing a directory is doable, but doesn't lend itself well to reusing components and sane system management. When you use RPM/DPKG for manging your configuration, each package you install is responsible for its own files and nothing more. The packaging system makes sure that nothing conflicts or overwrites existing files. If you accidently untar a file with bad configuration files in it, they will probably overwrite your existing configuration. RPM/DPKG will save your old configuration files. Tar can't help you verify that what you installed is what is actually running. RPM -verify can make sure that no trojan has been installed instead of a file provided in an RPM file. And the list goes on and on. > Does anybody see how simple it is to upgrade UWImap with its one binary? Just as long as there is only one binary. AFAIK, UWImap doesn't support configuration files, on the assumption that the sysadmin probably doesn't know enough to create a valid configuration. The downshot of that is that there is a limit to what you can do with UWImap's one binary :-) Lior > > Lior Okman wrote: > > Looking at the debianized version, the bulk of the files are placed in > > € > > or under /usr/lib/dovecot, with all of the configuration files in > > € > > /etc/dovecot, and relevant binaries under /usr/bin and /usr/sbin. > > € > > > > € > > However, reading from the comment in the begining of the default > > € > > dovecot.conf file, you can probably compile your own version of > > € > > dovecot where you specify the following parameters to configure: > > € > > "--prefix=/usr --sysconfdir=/etc --localstatedir=/var > > € > > --with-ssldir=/etc/ssl". > > € > > Just make sure to replace all the paths with where you want to install > > € > > this version of dovecot. > > € > > > > € > > Lior > > € > > > > € > > On 3/7/06, Stewart Dean <sdean(a)bard.edu> wrote: > > € > > > >> Hmmm, hadn't thought of RPM.

if you run configure --help, you will see this (and more): > Installation directories: > --prefix=PREFIX install architecture-independent files in PREFIX > [/usr/local] > --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX > [PREFIX] > > By default, `make install' will install all the files in > `/usr/local/bin', `/usr/local/lib' etc. You can specify > an installation prefix other than `/usr/local' using `--prefix', > for instance `--prefix=$HOME'. > > For better control, use the options below. > > Fine tuning of the installation directories: > --bindir=DIR user executables [EPREFIX/bin] > --sbindir=DIR system admin executables [EPREFIX/sbin] > --libexecdir=DIR program executables [EPREFIX/libexec] > --datadir=DIR read-only architecture-independent data [PREFIX/share] > --sysconfdir=DIR read-only single-machine data [PREFIX/etc] > --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com] > --localstatedir=DIR modifiable single-machine data [PREFIX/var] > --libdir=DIR object code libraries [EPREFIX/lib] > --includedir=DIR C header files [PREFIX/include] > --oldincludedir=DIR C header files for non-gcc [/usr/include] > --infodir=DIR info documentation [PREFIX/info] > --mandir=DIR man documentation [PREFIX/man] I see now I missed something so I will redefine my request. If I invoke configure with: --prefix=/usr/local/dovecot-bld/<timestamp> --eprefix=/usr/local/dovecot-bld/<timestamp> where /usr/local/dovecot-bld/<timestamp> is a directory Q1: Will I have everything in that one directory so that by tar'ing and untar'ing that one directory I can tar up everything necessary to run dovecot on another machine with the same OSlevel/patches/OpenSSL. Will dovecot be able to reference everything it needs? I notice that --oldincludedir=DIR C header files for non-gcc [/usr/include] will not be there. Will that be a problem? Q2: Will dovecot not be able to find system resources it needs? Tar'ing up a directory is doable. RPM'ing hundreds of files scattered here and there, perhaps referenced by others, perhaps with new additions/deletions you don't know about sounds like an heroic task. Does anybody see how simple it is to upgrade UWImap with its one binary?

[Dovecot] dspam plugin mailing list?
by Johannes Berg 07 Mar '06

07 Mar '06

Hi, Every once a while I get mail about my dspam plugin. While that's great (tells me people are using it or at least like the idea), sometimes I think the discussions then should be accessible to others. I'm thinking of setting up a new mailing list for it so answers get archived, are searchable, and I don't necessarily have to reply to everything. I'm not sure if that's feasible though, there probably aren't *that* many users, and sometimes the questions are more dovecot questions. Would anyone on this list (esp. Timo of course) mind if I were to note on the plugin page that discussion and questions should be sent to this (the dovecot) mailing list? I'll still be reading here and answering questions, of course, but then if something crops up that's more dovecot than plugin related it's at the right place already, or if I'm off for a few days and someone else knows the answer... If there are any objections I'll just set up a private mailing list instead and ask anyone interested to join (it'd be very low volume I guess) :) johannes

[Dovecot] mbox sync: UID inserted in the middle of mailbox...
by Simon Bowden 07 Mar '06

07 Mar '06

Hi, We're getting a lot of errors like this: Mar 7 10:02:35 imapserver dovecot: imap(user1): mbox sync: UID inserted in the middle of mailbox /home/user1/mail/mail/INBOX.Trash (8 > 2, seq=2,idx_msgs=6) We have several hundred people using the server, and at least 22 have had this error in the past 24 hours. The numbers at the end change between each user, which I guess you'd expect. I was able to make the errors go away for one user by removing the index files (rm -rf ~/mail/.imap/INBOX), so I'm guessing they were corrupt. However, the problem with this is that: 1) It requires user intervention 2) The symptom is that they aren't seeing any new mail in the affected mailbox. I had thought that the indexing stuff would not *give up*, but would reindex a directory if there was a problem. Anyone able to help? Some info on our setup: /home/user is nfs-mounted. We allow them to configure their mbox/maildir type and location, but obviously this is only relating to mbox ones. Here's the config file, stripped of comments and blank lines: ==================== protocols = imap imaps ssl_cert_file = /etc/ssl/certs/imapd.cert ssl_key_file = /etc/ssl/private/imapd.pem ssl_ca_file = /etc/ssl/certs/cacert.pem log_timestamp = "%Y-%m-%d %H:%M:%S " login_processes_count = 6 first_valid_uid = 40 mail_extra_groups = default_mail_env = mbox:~/mail/:INBOX=~/.incoming-mail mmap_disable = yes mail_drop_priv_before_exec = yes protocol imap { mail_executable = /usr/local/mail/imap-wrapper imap_client_workarounds = outlook-idle delay-newmail tb-extra-mailbox-sep } protocol pop3 { } auth default { mechanisms = plain gssapi passdb pam { args = session=yes * } userdb passwd { } user = root } plugin { } ==================== /usr/local/mail/imap-wrapper is just a script that lets them configure the setup a bit (effectively change value of MAIL, and some namespace stuff), ultimately running /usr/lib/dovecot/imap. The nfs mount options on the home directory mount are: rw,hard,intr,rsize=8192,wsize=8192,nosuid,nodev,vers=3,proto=udp Thanks! Cheers, - Simon

[Dovecot] Dovecot as a smart IMAP proxy
by Timo Sirainen 07 Mar '06

07 Mar '06

Do you see a use for an IMAP proxy where the proxy would be able to execute hooks which modify mail contents, such as transparent encrypting/decrypting mails, or maybe some virus-filtering? It would need at least some kind of IMAP command/reply parsing capabilities, so it might be able to do all kinds of other things. Maybe one potential use case would be Cyrus Murder-like proxying to multiple IMAP servers to distribute the mailboxes. But that might be done better as an imap process plugin, or maybe as IMAP mail storage backend. Anyway, the reason I'm asking this is because I was asked to add mail encryption/decryption capabilities to Dovecot's IMAP proxy, but I'm not sure what would be the best way to handle this. In any case it would be a plugin or a new binary which is executed instead of imap binary, but can I do it in a way that would actually be useful for Dovecot project in general?
