[Dovecot] problems with dotlock
by Mark Hedges 04 Mar '09

04 Mar '09

I have to make dotlock work because this openwebmail thing only supports one of dotlock or flock, but procmail delivery does dotlock and fcntl. procmail correctly creates a dotlock file in /var/spool/mail/username.lock when delivering, I can watch this with `while :; do ls -la | grep lock; done`. It works fine when lock_method=fcntl, but no dotlock file shows up in /var/spool/mail. mbox_write_locks are working correctly with mbox_write_locks = dotlock fcntl, the dotlock file shows up in the user's mail directory. However, dotlocking /var/spool/mail doesn't work: $ ls -la /var/spool/mail total 44 drwxrwxr-x 2 root mail 4096 Feb 25 17:39 . $ grep mail_privileged_group /etc/mail/dovecot.conf mail_privileged_group = mail Feb 25 17:45:45 anubis dovecot: POP3(despam_test_anubis): Effective uid=511, gid=100 Feb 25 17:45:45 anubis dovecot: POP3(despam_test_anubis): mbox: data=/home/anubis/despam_test_anubis/mail:INBOX=/var/spool/mail/despam_test_anubis Feb 25 17:45:45 anubis dovecot: POP3(despam_test_anubis): mbox: root=/home/anubis/despam_test_anubis/mail, index=/home/anubis/despam_test_anubis/mail, inbox=/var/spool/mail/despam_test_anubis Feb 25 17:45:45 anubis dovecot: POP3(despam_test_anubis): file_lock_dotlock() failed with mbox file /var/spool/mail/despam_test_anubis: Permission denied Feb 25 17:45:45 anubis dovecot: POP3(despam_test_anubis): Couldn't open INBOX: Internal error occurred.

[Dovecot] GSSAPI cross-realm still broken
by Bryan Jacobs 03 Mar '09

03 Mar '09

I've been trying to track down some problems with Dovecot in a Kerberos 5 cross-realm environment, and there seem to be a few issues. LOGIN/PLAIN work fine using pam_krb5, but GSSAPI is a bit harder to handle. On line 436 of src/auth/mech-gssapi.c, the authn_name and the authz_name are compared using gss_compare_name. This dates back to the message at: http://dovecot.org/pipermail/dovecot/2005-October/009615.html While everything within that message is true, as things stand, Dovecot is unusable in a cross-realm environment. When cross-realm tickets are used, the authn_name is "username@REALM" and the authz_name is "username" (or vice versa, I don't remember). The attached patch causes dovecot to display these two values in human-readable format to illustrate the issue. Because these two GSS names differ, Dovecot refuses to allow access in spite of the fact that krb5_kuserok would return TRUE. I am not the only one to have noticed this problem: http://dovecot.org/pipermail/dovecot/2007-July/023868.html http://dovecot.org/pipermail/dovecot/2007-October/026027.html Might I suggest that some more robust security checking be done instead of abusing gss_compare_name like this? I don't know how to do this using GSSAPI, but on the Kerberos side Heimdal provides the function krb5_kuserok. Dovecot could also just have a configurable file listing acceptable krb5 principals (preferably in .k5login syntax) and check that both auth_name and authz_name are in the list. Bryan Jacobs

[Dovecot] Anyone know or have a perl, c/c++ script?
by Brandon Lamb 03 Mar '09

03 Mar '09

Hello all, Im hoping maybe someone on this list has already looked for or built something similiar. Basically from what I can tell, phps imap libraries or whatever dont support setting custom keywords. So I am wondering if someone has a library or script that can take a username, domain, password, folder, uid and flag to set so that my webmail app can call this to set imap keywords. So far my google searching isnt turning up anything, but searching for the word keyword doesnt really help.

[Dovecot] Seperate auth per protocol (pop3/imap)
by Guy 03 Mar '09

03 Mar '09

Hi, During discussions with the boss we've speculated about having users having only specific services available. One of the ideas was to have users being able to specify if they wanted POP3 or IMAP and whether we could limit their access to one or the other server side. We use MySQL for the userdb and passdb lookups at the moment. Is it possible to specify separate auth files with different MySQL lookups per protocol? Thanks Guy -- Don't just do something...sit there!

[Dovecot] dovecot imap and thunderbird tags
by Lorenzo Bettini 02 Mar '09

02 Mar '09

We've been using an imap(s) dovecot server for a while on an ubuntu 8.04.2 and we noted that tags set by thunderbird ("important", "to do", etc.) are almost always lost, i.e., when connecting to the same imap account from another machine, the tags are not there anymore... this always happens for the Inbox, and seldomly for other imap folders... anyone else experiencing this? Note that the same problem does not arise with other imap server accounts... thanks in advance Lorenzo -- Lorenzo Bettini, PhD in Computer Science, DI, Univ.

[Dovecot] Maildir format use question
by Rick Romero 02 Mar '09

02 Mar '09

Hey all, I've got a couple servers using Maildir format. As I understand it from a simple perspective, 'new' contains newly delivered messages, and 'cur' contains messages that have been 'handled'. I like to keep things simple for users, so rather than have 'Spam', 'Junk' 'ToLearn' and other possibly confusing folders, what I thought I would do is scan their .Spam/cur folder for mail that was older than an hour (based on file atime(?) stamp) and feed that through SpamAssassin. The idea being that anything in 'cur' would: 1. have been moved there by the user. 2. be recently read, and I think if it were innocent, would be handled within an hour 3. Not contain newly delivered, unread mail. This is actually what I see when I view my Spam folder through Evolution. If I use a PHP webclient - either Horde or Roundcube (I've captured the debugs if you'd like them), then a simple view of the Spam folder causes the files to be moved from new/ to cur/. They are updated with the :2, - but since nothing was actually done, no flags are added. So I'm left with a quandry. I guess the simple question is, Should mail in cur, EVER not have a flag? I suppose if it were marked as UNSEEN after being SEEN, that's possible. So I just answered myself there :) Is it possible to have Dovecot NOT move a file from new/ to cur/ until a flag has been assigned to the mail? Just from a, possible, performance standpoint - it seems when accessing an INBOX from a PHP webmail system with MANY new mails, there is an unnecessary(?) mass move of these files to another folder. Thoughts? Rick

[Dovecot] Forwarding with Dovecot
by Sawtooth500 02 Mar '09

02 Mar '09

I'm using Dovecot with Postfix as my MTA I need to set up forwarding with Dovecot. I create a .forward file in my user's home directory, and in the .forward file I put destination_email_address email(a)example.com. Well, it got delivered to the forwarded email just fine. But the sender also got an undeliverable email from the dovecot mailbox and a copy was not saved in the dovecot mailbox. I need emails forwarded, and a copy saved in the dovecot mailbox. Thanks in advance for the help! -- View this message in context: http://www.nabble.com/Forwarding-with-Dovecot-tp22244316p22244316.html Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Remote storage
by Daniel L. Miller 01 Mar '09

01 Mar '09

What options are available for remote storage, i.e. storage devices directly mounted on the machine running Dovecot? I've seen discussions of NFS usage - but my experiences with NFS in times past have been poor. CIFS has worked well for me for non-mail use - would this be suitable? Or is there another method I've not considered? -- Daniel

[Dovecot] Compilation Issue on Old Boxes with macro in src/master/main.c
by Kevin A. McGrail 28 Feb '09

28 Feb '09

I'm throwing an error compiling with a custom-compiled gcc 3.2.3 on one box. The configuration string is CC=/usr/local/gcc3.2.3/bin/gcc CPPFLAGS=-I/usr/local/ssl/include LDFLAGS=-L/usr/local/ssl/lib ./configure --with-ssl=openssl --with-ssldir=/usr/local/ssl/certs --with-pam --with-pop3d --sysconfdir=/etc --localstatedir=/var I've used this to compile on other older boxes with success. And I compared the command lines and they are identical. This is the error I get with src/master/main.c main.c:365:1: directives may not be used inside a macro argument main.c:364:16: unterminated argument list invoking macro "printf" main.c: In function `print_build_options': main.c:372: syntax error before string constant Changing the function to a simpler function without the ifdef's resolves the issue and dovecot compiles. I would really like to know why two boxes with the same compiler are failing on one but not the other. Perhaps there's some program or library or preprocessor or path or something out of whack. Especially since using gcc 2.96 on the same box works! However, I since this is a simple options output routine and (from my cursory read) there may be some standards issue with this technique, I've also patched the issue. http://www.peregrinehw.com/downloads/dovecot/dovecot-1.1.11-build_options_m… Thoughts?

[Dovecot] Custom flags in v1.0.15
by Pascal Mouret 28 Feb '09

28 Feb '09

Hello all, I'm having problems with setting custom flags on a dovecot imap setup, with mbox mail store. I was running v1.0rc15 on a Debian Etch box, upgraded recently to v1.0.15, but nothing changed. The problem : I read my mail using IMAP. In Thunderbird (various versions, current one being v2.0.0.19), I can set various message flags (Important, Personal, Work, ... mapped to IMAP as $Label4,$ $Label3, $Label2, ...). I read my mail from several machines, but all changes made on the message flags from one machine won't appear on the others !? Still I've read that those flags are supported in Dovecot. Actually, I logged the IMAP traffic, and saw that Dovecot claims to "handle" them. For instance, I added a flag to a message : Thunderbird > 621 uid store 35150 +FLAGS ($label4) Dovecot > * 6716 FETCH (UID 35150 FLAGS (\Seen \Recent $Label4)) Now, if I close TB, so that changes are written to the mbox file, and if I open that file on a the server with any text editor, the 'X-Keywords' line doesn't appear !? And as a matter of a fact, if I read my mail from any other machine, the flag isn't set ! Anyone knows where the problem can be ? Do I need to upgrade to v1.1 ? Or are custom flags actually supported in v1.0 (which I believe is the case) ? I browsed through the internet and searched the archives of this mailing list but didn't find any clue ... Any help would be much appreciated Thank you very much in advance Pascal Mouret -- Pascal Mouret Responsable du Service Informatique Polytech' Marseille, Université de Provence 60, rue Joliot-Curie / 13453 Marseille cedex 13 Mel : pascal.mouret(a)polytech.univ-mrs.fr Tel : 04 91 11 38 04 / Fax : 04 91 11 38 54

This: Feb 16 10:05:56 server dovecot: Panic: IMAP(user): file istream-tee.c: line 144 (i_stream_tee_read): assertion failed: (ret > 0) auth-worker died. That happened with Dovecot 1.1.4, 1.1.7 and 1.1.11, 1.1.7 was not with me, was with another user I found, on some mailing list. The problem occurred when copying or deleting messages, sometimes even viewing (Webmail). Since it's a production server, I compiled the latest 1.0.x and I'm using it. This particular server was running Ubuntu 8.04 (the default package is 1.0.x) and I upgraded to 8.10 (the default package is 1.1.x). > > > Is it possible to have Dovecot on one machine serving two different domains? > > Set up how? Do you want to use user@domain style usernames, or do you > want Dovecot to detect the domain based on the server's IP address? One dovecot server which receives mail to two domains and does not forward the mail anywhere, it's the final destination for the two of them. I already have usernames that are unique, by using Dovecot variables I have username~domain.org as the actual username/mailbox name. I want to have two mailbox roots, this way, even knowing that mailbox names are unique (john~domain.org != john~anotherdomain.org) and when authenticating (from what you wrote down here about passdb) john(a)domain.org will not be confused with john(a)anotherdomain.org, even so, I want all mailboxes from one domain to sit on a different mailbox root. > > > Is is possible to set a LDAP config to one domain and another > > LDAP config to the other (the auth part, I wan't users to reside > > on different bases on my LDAP tree, so search bases need to be > > different) > > Yes. You can just create two passdb ldap {}s. Ok, so, I have 3 aspects to consider: a) When mail arrives b) When user logs in to check mail c) Where mailboxes are located a) Since I can make mailbox names unique with Dovecot variables (mailbox name is "susan~domain.org" which is different from susan~anotherdomain.org) when mail arrives, the mail message will be saved to the correct mailbox (even if I have, under the same mailbox root, two users with "susan" as the login, but from different domains). b) Since you said, on Dovecot 1.0.x, I can have two passdb ldap{}'s, when the user logs in, he/she will be redirect to the right mailbox, not the "other susan". c) Ok, the two above give me the possibility to have all mailboxes, from the two domains, under the same mailbox root, users will be unique no matter the scenario (mail arriving, user checking mail), BUT, I would like to keep them separated anyways, is that possible to force that? > thanks! = Miata Convertible Tops Buy manufacturer direct from gahh, leader in high-quality convertible tops using original materials and attachments.

[Dovecot] Quota + Sieve
by Linux Advocate 27 Feb '09

27 Feb '09

Thanx to everybody's help , i have got a working combination of; - dovecot LDA - smtp auth thru dovecot sasl - postfix - virtual users in mysql - postfixadmin - thunderbird as the email client Just 2 additional questions - A. Sieve .............. With the imap filters in thunderbird, do i need to use sieve in dovecot? my initial observations/ findings say "no"? B. Quota ............. If i have not set quota in dovecot or postfix ( no quota related configuration ), may i then assume, the users have "unlimited storage" , limited only by the hardware/filesystem? I would like to have this feature ( just like unlimited storage in yahoo ) and just have a cron script running regularly to delete old emails ( for middle level, low level users ). Is such a strategy ok? regards, mgomez

From there it didn't take long to figure out that something had changed with update of Dovecot that no longer allowed this configuration line to work: mail_location: ~/Maildir and both in dovecot.conf and log I was warned to add the prefix "maildir"" With this everything seems to be fixed. I don't know whether this would be considered any kind of bug. The Debian package allowed me to upgrade Dovecot without warning me that the rules for mail_location had changed.

[Dovecot] internal raw storage - dovecot deliver in /tmp
by lejeczek 26 Feb '09

26 Feb '09

is it configurable anywhere on the runtime level, is it configurable at all selinux policy does not allow for transition between some domains that subsequently results in deliver not being granted permissions it needs to write to /tmp instead of compiling a policy module I wonder what is the matter with that raw storage and /tmp? cheers ___________________________________________________________ Try the all-new Yahoo!

[Dovecot] Quick question...
by dovecot＠segel.com 26 Feb '09

26 Feb '09

Hi, Here's the scenario. I want to set up a mailbox so that when mail sent to the address is piped to a processing application, instead of going to a mailbox. One way I can do this is to set up a mailbox and then have an application that checks to see if there's mail and then processes it. (Old school Unix script) Is there a way to set it up with dovecot? (Cleaner solution) Thx -Mike

[Dovecot] exim4 + dovecot + SquirrelMail virtualhosted on Debian
by Tim Legg 25 Feb '09

25 Feb '09

Hello, I have a Debian machine that is virtual-hosting 6 domains with exim4. I finally got exim4 working well enough where I can send and receive mail using the mail command on my machine. I would eventually like to have SquirrelMail (which requires IMAP) working on my website. For whatever reason, exim4 doesn't seem to support IMAP. I found out that Dovecot is a prominent IMAP server. So I installed the most current Dovecot package (1.0.rc15) in Debian. Something is broken though... As I log into SquirrelMail, I get an error message "Error connecting to IMAP server: localhost. 111 : Connection refused". To investigate, I decided to telnet localhost on port 143 and found out that yes, the connection is in fact refused. So what do I need to do in order to have dovecot listen on port 143? Also, I noticed when I restart dovecot... debian:/etc/dovecot# /etc/init.d/dovecot restart Restarting mail server: dovecotError: Can't use mail executable /usr/lib/dovecot/imap: No such file or directory I hope this isn't a serious problem. Thanks Tim Legg

[Dovecot] imap SORT core dumps on beta1

All fail but 777. ps -ef|grep exim shows that exim is run by user 101. A look into /etc/group reveals the user as libuuid. Debian-exim is user 103. Could this be what is causing my problems?

[Dovecot] Securing mailboxes and passwords
by Daniel Aleksandersen 25 Feb '09

25 Feb '09

Hi list I am just experimenting with seting up my own email server. I want some tips and hints on how to secure my setup to prevent unauthorised assess to my email. I have read through the wiki and have not found many tips. I hope to improve the wiki with tips gathered from the emailing list. :-) A basic measurement I could take right now would be to set more secure file premissions on my setup. My setup is based on http://wiki.dovecot.org/HowTo/VirtualhostingWithExim with a few addittions: fetchmail and exim4 deliver mail to my maildir and dovecot grants me access through imap. dovecot authenticates against /home/postmaster/passwd.digest and ./passwd.cram -- Daniel Aleksandersen <aleksandersen(a)runbox.no>

[Dovecot] Calling dovecot deliver from procmail
by Harry Lachanas 25 Feb '09

25 Feb '09

I came up with this trick That is Since my previous mail server had a bunch of complex procmail recipies and I am not sure that I can turn them into sieve scripts I am calling dovecot deliver to drop mail in it's final $DEFAULT destination. :0 | /some/path/dovecot/deliver in order to update the index, control files etc upon delivery time. So far in my "tests" it works. But I wonder if this is wise or not. Regards, Harry.

[Dovecot] Dovecot problem after last Debian sid update

Hi All, After upgrading dovecot for sid Thunderbird no longer displays the contents of any emails I have had a working IMAP setup for as much as a year even though I don't understand dovecot configuration well enough to know how I got it to go in the first place. Here is the output of dovecot -n # 1.1.11: /etc/dovecot/dovecot.conf # OS: Linux 2.6.26-1-vserver-686 i686 Debian 5.0 log_timestamp: %Y-%m-%d %H:%M:%S disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_location: ~/Maildir auth default: passdb: driver: passwd-file args: /etc/passwd.dovecot userdb: driver: passwd TIA for any clues as what to do next.

[Dovecot] OT: Fixing Messages To Be RFC 2822 Compliant
by Neil 25 Feb '09

25 Feb '09

So....apparently I have some messages which are not RFC compliant sitting in my mailboxes (mostly older ones), and I have some software which is refusing to handle such messages. 1. Does anyone know of a nice way to verify that all my messages are compliant/find those that aren't? (I suppose I could use the existing failing software, but I was hoping for something a little more robust...) 2. Does anyone know of any tools that will do The Right Thing as far as fixing these messages are concerned? Googling didn't turn up much for me, but maybe I wasn't hitting the right terms ("RFC message repair", "fix email message", etc.). Thanks.

[Dovecot] Dovecot as a email storage system
by Roderick A. Anderson 24 Feb '09

24 Feb '09

I was thinking about all the old email I have and don't want to get rid of and how much space it is taking on my mail server. The idea came to me to install Dovecot on a server at home then I could drop mail into I want to save. It doesn't need to receive mail except what that is moved to it. Anyone see problems with doing this? Thanks, Rod --

[Dovecot] email stuck in outbox
by barnaby cockcroft 24 Feb '09

24 Feb '09

Can anyone here help me out with a client side Outlook issue? I know outlook is a horrible imap client :( We intermittently have a problem where mail gets "stuck" in Outlook users' outboxes. Might have anything to do with dovecot? Is there anyway I can troubleshoot this server side? Are there any settings I can tweak? We have a new and an old dovecot server (see below) and both exhibit the same behavior (occasionally) for heavy mail users. We haven't ruled out a layer 2 issue but nor have we found one.... If anyone has any ideas (other than suggesting a different email client), they'd be much appreciated. Dovecot version(s) 1.19 & 0.99.11 Configuration from 1.19: # 1.1.9: /usr/local/etc/dovecot.conf # OS: Linux 2.6.9-78.0.13.ELsmp i686 Red Hat Enterprise Linux ES release 4 (Nahant Update 7) ext3 syslog_facility: local0 ssl_cert_file: /usr/local/etc/ssl/**************** ssl_key_file: /usr/local/etc/ssl/***************** disable_plaintext_auth: no login_dir: /usr/local/var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login mail_location: mbox:/home/%u/mail:INBOX=/var/spool/mail/%u mbox_write_locks: fcntl auth default: debug: yes passdb: driver: pam userdb: driver: passwd

[Dovecot] Broken dovecot-uidlist files
by Ulrich Zehl 24 Feb '09

24 Feb '09

I have just upgraded to 1.1.8, hoping to fix these types of errors: Jan 20 10:39:27 laura deliver(xxxxxx(a)example.net): Broken file /srv/storage/mail/store/net/example/xx/xxxxxx/Maildir/dovecot-uidlist line 156: Invalid data: Jan 20 10:41:19 laura dovecot: POP3(yy.yy(a)example.at): Broken file /srv/storage/mail/store/at/example/yy.yy/Maildir/dovecot-uidlist line 2: Invalid data: Unfortunately, they still pop up. Since I suspect these errors to be responsible for customers complaining about downloading mails twice, I'd like to fix them. Our setup has multiple servers sharing the same NFS-mounted directory for maildirs and indexes; we have set mmap_disable = yes dotlock_use_excl = yes fsync_disable = no mail_nfs_index = yes lock_method = fcntl As far as I can tell, for at least one of these errors, there was no concurrent access to the mailbox in question. What can I do to solve this problem, or to analyze it further? Ulrich

This is with respect to an error that I am facing in dovecot.

[Dovecot] Postfix LDA vs the Dovecot LDA + other quetions
by Linux Advocate 24 Feb '09

24 Feb '09

Guys , 1. What is the benefit of using Dovecot' LDA as compared to postfix's LDA? Will there be better performance? And along the same vein, 2. What is the benefit of using Dovecot's SASL as compared to Cyrus SASL? Is there better performance? 3. Quota Management ( Creating, enforcing, notifying ) - is it done thru dovecot or postfix or are both needed? Regards, mgomez

[Dovecot] pkgsrc-ing sieve and managesieve
by Edgar Fuß 24 Feb '09

24 Feb '09

I'm trying to integrate both the new sieve implementation and managesieve into pkgsrc. Managesieve seems to need some dovecot libraries that dovecot doesn't install (lib-storage/libstorage.a, lib-auth/libauth.a, lib-imap/libimap.a, lib-index/libindex.a, lib-mail/libmail.a, lib-charset/libcharset.a, lib-dict/libdict.a and lib-charset/libcharset.a). There seems to be no provision in pkgsrc for the build of a package needing the work directory of the build of another package. Would it make sense for dovecot to install those libraries?

[Dovecot] sieve-test again
by Ian P. Christian 23 Feb '09

23 Feb '09

I'm not sure what it is I'm doing wrong here, perhaps my 'test' mail is not in the format expected by sieve-test. The 'test' file is a file taken directly from a dovecot maildir - so is in the normal format of having headers, a new line, then the body. There is nothing exceptional about this email. Notice how the header below is 'innocent', however it appears that the test is ignoring this header. # grep DSPAM-Res test X-DSPAM-Result: Innocent # cat sievetest require ["regex", "fileinto","envelope","reject","vacation","relational","comparator-i;ascii-numeric"]; if header :contains "X-DSPAM-Result" "Innocent" { fileinto "moo"; stop; } # sieve-test -c ./sievetest ./test Performed actions: (none) Implicit keep: * store message in folder: INBOX Info: final result: success I don't think it's this header, but rather *all* headers, as the following check also appears to fail. if header :contains "To" "o" { fileinto "Spam"; stop; } Am I mis-using the tool? Thanks, Ian

[Dovecot] from postfix deliver to dovecot deliver

Hello all. I use dovecot in combination with postfix, postfixadmin for virtual users. Deliver to the mailbox now is done by postfix Now i want to enable quota's and therefor i need dovecot deliver. Can i just switch to dovecot deliver? Or must i first do some prrperations in the mailboxes. regards -- _______________________ *Johan Hendriks* *Schavemaker Transport* Tel: +31 (0)251 229098 Fax: +31 (0)251 212016 email: j.hendriks(a)schavemaker.com <mailto:j.hendriks@schavemaker.com> web: http://www.schavemaker.com _______________________ /Confidentiality Notice: The information in this document may be confidential.

[Dovecot] lda catchall
by Stéphane Cottin 23 Feb '09

23 Feb '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I'm using dovecot lda in a qmail / vpopmail testing environnement. I would like to replace vpopmail lda with dovecot's one , because of quotas , sieve filers, indexing while delivering ... Everything is working great, except the catchall. If I want to bounce, a first line like "# bounce-no-mailbox" in the .qmail file works, without this line, emails to unknown addresses are deferred and stay in the queue, because they are deliverable for qmail, but not for dovecot lda. How can I set a catchall email address for dovecot lda ? thx Stéphane Cottin -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkmixCcACgkQNgQUYqHIqqvttQCfcNBLd9Qo06g5nMcrfZAwVlpv WegAnj7jIA/XFJWmt/2jkg1sxRYKRaI7 =JTTV -----END PGP SIGNATURE-----

http://dovecot.org/releases/1.2/beta/dovecot-1.2.beta1.tar.gz http://dovecot.org/releases/1.2/beta/dovecot-1.2.beta1.tar.gz.sig Largest changes since v1.1 can be found from http://dovecot.org/doc/NEWS-1.2 Changes since alpha5: - Added support for ESORT extension (also SORT .. RETURN (PARTIAL) from CONTEXT=SORT that allows windowing SORT results) - pop3: If client idles for 10 seconds, commit transaction (allowing mbox to become unlocked). - crashfixes to virtual mailboxes - all kinds of bug fixes, error message improvements, etc. - http://dovecot.org/patches/1.2/stats-plugin.c may give some interesting statistics about commands There isn't really much left to do for v1.2.0 except some small fixing to shared mailbox code. And writing documentation for it..

[Dovecot] IMAP ACLs and global ACLs in v1.2
by Timo Sirainen 23 Feb '09

23 Feb '09

I just committed code for IMAP ACL support based on the code from Kolab people. I did quite large changes though. I also changed how global ACLs are handled. Previously local ACLs could override global ACLs, but now that users are able to modify the ACLs I think it should be the other way around. From what I've heard global ACLs are typically added for things like 1) disallowing user from doing something in specific mailboxes such as expunge messages, 2) giving a specific master user access to some mailboxes ONLY, such as voicemail. For 1) case a user really shouldn't be able to grant himself privileges back but still should be able to share the mailbox to others (so the global ACL should have 'a' privilege). For 2) case a user shouldn't be able to remove privileges from the voicemail. So now the user can freely update the local ACLs in whatever way he wants. But in the end if there are any global ACLs, all the local ACLs for those identifiers are ignored. Also local negative identifiers are ignored, so that e.g. global "user=foo lr" can't be disabled by a local "-user=foo lr" ACL. I guess I should update the Wiki ACL page about how exactly the ACLs are applied now that they're well in my memory. :) One thing I'm not really sure about is the "owner" handling. IMAP ACL specifications have no such concept. I think many/most other servers simply add a default ACL for the user name directly. It's a useful concept though, especially with the global ACLs. So currently Dovecot replies: x getacl inbox * ACL "inbox" "owner" lrwstiekxacd x OK Getacl completed. But should it just internally convert "owner" to "username" when replying? But then again if there's a separate rule directly for the "username" it breaks. Do any of the existing ACL-capable IMAP clients want to see the username in the ACL reply or can they handle "owner" just fine? Also what about global ACLs? The current code just lists them twice with local ACLs, which is definitely wrong: x getacl foo * ACL "foo" "xx" w "xx" lr "owner" lrwstiekxacd x OK Getacl completed. Perhaps the global ACLs could have a prefix character? Maybe '#'? Which reminds me, the current dovecot-acl file is mapped to IMAP ACLs like this: dovecot-acl : IMAP ACL - anyone : anyone - authenticated : authenticated - owner : owner - user=name : name - group=name : $name - group-override=name : !$name So all global ACLs would get the # prefix, like #anyone, #name, #!$name. Any thoughts? BTW. Listing shared mailboxes still doesn't work. I guess we'll see tomorrow if I still have energy to get that done.

[Dovecot] dovecot auth
by ben 23 Feb '09

Hi, I'm using dovecot with a passdb-file . When I login using : test(a)testdomain.com I notice dovecot strips off the domainname and looks up everything in front of the @ in his passdb-file... So I went on to configure the following in my dovecot.conf : auth_username_format = %u@%d restarted dovecot, but he still strips of the @ and the domainname ... LOG (sorry for f* up format) : dovecot: Feb 21 12:15:08 Info: auth(default): new auth connection: pid=24483 dovecot: Feb 21 12:15:12 Info: auth(default): client in: AUTH 1 PLAIN service=pop3 lip=195.207.136.102 rip=195.207.136.108 lport=110 rport=36132 resp=AGJlbkBpdHV4LmJlAHRlc3QxMjMu dovecot: Feb 21 12:15:12 Info: auth(default): passwd-file(test@testdomain.com@testdomain.com,195.207.136.108): lookup: user=test file=/opt/dovecot/etc/dovecot.passwd dovecot: Feb 21 12:15:12 Info: auth(default): passwd-file(test@testdomain.com@testdomain.com,195.207.136.108): unknown user dovecot: Feb 21 12:15:14 Info: auth(default): client out: FAIL 1 user=test(a)testdomain.com Can someone enlighten me on how to config it so he looks up "test(a)testdomain.com" fully ? thx

[Dovecot] TLS / Dovecot / POP3
by John Espiro 22 Feb '09

22 Feb '09

I am using Thunderbird 2.x as my client, Dovecot on the server (POP3 not IMAP). Currently I have in my conf file: protocols = pop3s pop3 ssl_disable = no ssl_cert_file = /usr/share/ssl/certs/dovecot.pem ssl_key_file = /usr/share/ssl/private/dovecot.pem ssl_parameters_file = /var/run/dovecot/ssl-parameters.dat disable_plaintext_auth = yes login = pop3 In Thunderbird, I have the email server setup to: - Port 110 - TLS Here's my question: If I change protocols = pop3s pop3 to protocols = pop3s I can no longer connect to my mail server via Thunderbird unless I setup Thunderbird to use SSL. Am I doing something wrong? Thanks, John
