[Dovecot] suspect valgrind error in mail-index-map.c
by Diego Liziero 10 Mar '08

10 Mar '08

Hi At line 1118 of src//lib-index/mail-index-map.c, inside the function mail_index_map_move_to_memory, there is: mail_index_map_copy_header(map, map); Valgrind is stating that "Source and destination overlap in memcpy". I'm wondering if this code is just coping the same memory over itself, or if it is doing something useful. Regards, Diego Liziero. --- 1104 void mail_index_map_move_to_memory(struct mail_index_map *map) 1105 { 1106 struct mail_index_record_map *new_map; 1107 1108 if (map->rec_map->mmap_base == NULL) 1109 return; 1110 1111 i_assert(map->rec_map->lock_id != 0); 1112 1113 new_map = array_count(&map->rec_map->maps) == 1 ? map->rec_map : 1114 mail_index_record_map_alloc(map); 1115 1116 mail_index_map_copy_records(new_map, map->rec_map, 1117 map->hdr.record_size); 1118 mail_index_map_copy_header(map, map); 1119 1120 if (new_map != map->rec_map) { 1121 mail_index_record_map_unlink(map); 1122 map->rec_map = new_map; 1123 } else { 1124 mail_index_unlock(map->index, &new_map->lock_id); 1125 if (munmap(new_map->mmap_base, new_map->mmap_size) < 0) 1126 mail_index_set_syscall_error(map->index, "munmap()"); 1127 new_map->mmap_base = NULL; 1128 } 1129 }

[Dovecot] Automatic Debian repository with packages for Dovecot-1.1 including Sieve and ManageSieve support.
by Stephan Bosch 10 Mar '08

10 Mar '08

Hello Dovecot users, For those of you who like to live on the edge, there is now a Debian-testing repository available with hourly updates from recent Dovecot-1.1 changes in the Mercurial repositories. It automatically releases a new set of packages if it notices any changes in any of the repositories. The packages are built with dovecot-sieve-1.1 and dovecot-1.1-managesieve included. Currently, it only provides binaries for the i386 architecture and no source packages are available. The small Debian-specific patches that are included in the official Debian packages are currently not included for this repository. Also, the packages are currently not PGP signed. I've built this repository to obtain continuous updates on whether the managesieve patch and package still compile and work with the latest Dovecot release. I get an e-mail if anything goes wrong during the build. I implemented the cron script right at the release of dovecot-1.1.rc1 and now that it successfully upgraded the package versions to 1.1.rc2, I decided to release the repository to the world. Needless to say: do **NOT** use this repository for systems that need to be **STABLE**. Usage should be similar to the backports.org repository (http://www.backports.org/dokuwiki/doku.php?id=instructions) but add the following line to your /etc/apt/sources.list: deb http://xi.rename-it.nl/debian/ testing-auto main Package versions look as follows: 1:<upstream-version>~auto+<build number> Current latest version: 1:1.1.rc2~auto+1 For questions, comments and requests, you can send me an e-mail. Regards, -- Stephan Bosch stephan(a)rename-it.nl IRC: Freenode, #dovecot, S[r]us

[Dovecot] Telephone systems and Dovecot
by Jonathan Knight 10 Mar '08

10 Mar '08

Hi folks, We're looking to integrate our telephone system with our email system. The telephone system will use IMAP4 to store WAV files in a users mailbox and then retrieve them for playing if necessary. This is usually called "unified messaging". The manufacturers are claiming full integration with Microsoft Exchange and Lotus Notes using IMAP4 and a single username and password to access all the users mailboxes. I can see that Dovecot has a master user feature that looks like it will do the job. Has anyone had any experience of using dovecot as a unified message server for a telephone system and has anyone any experience of configuring dovecot so that an MS exchange IMAP4 client using a master user can use dovecot without changing the client? Jon.

[Dovecot] v1.1.rc2 released
by Timo Sirainen 09 Mar '08

09 Mar '08

http://dovecot.org/releases/1.1/rc/dovecot-1.1.rc2.tar.gz http://dovecot.org/releases/1.1/rc/dovecot-1.1.rc2.tar.gz.sig Changes since rc1: * mail_extra_groups setting was commonly used insecurely. This setting is now deprecated. Most users should switch to using mail_privileged_group setting, but if you really need the old functionality use mail_access_groups instead. + Expire plugin now supports wildcards in mailbox names. + dbox: Expire plugin supports moving old mails to alternative dbox directory + Maildir++ quota: quota_rule=?:<rule> specifies a default rule which is used only if the maildirsize file doesn't exist. + If SSL/TLS connection isn't closed cleanly, log the last error in the disconnection line. + EXPUNGE: If new \Deleted messages were found while expunging, do it again and expunge them as well (Outlook workaround) - IMAP: SEARCH, LIST and THREAD command correctness fixes - Maildir++ quota: Quota rules and warnings with % rules didn't work if the default limits were taken from maildirsize file. - Maildir++ quota: If both byte and message limits weren't specified, maildirsize file was recalculated all the time - mbox: Flag and keyword updates may have gotten lost in some situations (happens with v1.0 too) - ldap: Don't crash if userdb lookup fails - Squat fixes and performance improvements Things left to do for v1.1.0: - dbox has a metadata corruption bug, find and fix it - Squat has some locking issues that causes errors when stress testing with multiple connections - Squat doesn't do NFS cache flushing and has some other NFS problems.

[Dovecot] v1.0.13 and v1.1.rc3 released
by Timo Sirainen 09 Mar '08

09 Mar '08

http://dovecot.org/releases/1.0/dovecot-1.0.13.tar.gz http://dovecot.org/releases/1.0/dovecot-1.0.13.tar.gz.sig http://dovecot.org/releases/1.1/rc/dovecot-1.1.rc3.tar.gz http://dovecot.org/releases/1.1/rc/dovecot-1.1.rc3.tar.gz.sig Note that the changes for the security hole fix were quite large. I tested with several auth configurations myself and they seemed to work, but it's possible I left a bug somewhere in there breaking someone's configuration. So make sure to test that it works after upgrading. Of course it would be really nice if Dovecot had a proper test suite where testing all configurations could be automated and run before each release. I've already started this with my imaptest tool (http://imapwiki.org/ImapTest) but it only does IMAP tests and a lot of things are still missing. Some help would be nice here. * Fixed a security hole in blocking passdbs (MySQL always. PAM, passwd and shadow if blocking=yes) where user could specify extra fields in the password. The main problem here is when specifying "skip_password_check" introduced in v1.0.11 for fixing master user logins, allowing the user to log in as anyone without a valid password. - mail_privileged_group was broken in some systems (OS X, Solaris?) - IMAP THREAD: Fixed some correctness problems

[Dovecot] Security hole #6: Some passdbs allowed users to log in without a valid password
by Timo Sirainen 09 Mar '08

09 Mar '08

This affects only blocking passdbs: - MySQL - PAM, passwd and shadow if blocking=yes The underlying bug exists in all v1.0.x versions, but I couldn't figure out a way to exploit it except with v1.0.11, v1.0.12 and v1.1.rc2. Probably a good idea to upgrade in any case. The main problem is that Dovecot's internal protocols use TAB character as a delimiter, but passwords were sent unescaped through them. So passwords containing TAB characters allowed to add new internal fields. The main problem here is a new "skip_password_check" field added in v1.0.11 to fix problems with master user logins. Specifying this field allowed the user to skip the password check, as the name implies. This has been fixed thoroughly in v1.0.13 and v1.1.rc3 to make sure there are no more escaping problems with any fields, but it can be also fixed with a less intrusive patch for v1.0: http://hg.dovecot.org/dovecot-1.0/raw-rev/da2a9372e26e

[Dovecot] Quota Problem?
by Michel Vega Fuenzalida 08 Mar '08

Good list I am not very good with English. I use dovecot-1.0-1.2.rc15.el5.x86_64rpm for Centos 5.1, Maildir like mailbox and I have it configured as it continues: base_dir = /var/run/dovecot/ protocols = imaps pop3s imap mail_location = maildir:~/Maildir protocol imap { mail_plugins = quota imap_quota mail_plugin_dir = /usr/lib/dovecot/imap } protocol pop3 { pop3_uidl_format = %08Xu%08Xv mail_plugins = quota mail_plugin_dir = /usr/lib/dovecot/pop3 } log_path = /var/log/dovecot.log log_timestamp = "%b %d %H:%M:%S " syslog_facility = mail auth default { mechanisms = plain #login digest-md5 cram-md5 passdb pam { } userdb passwd { } user = root } plugin { quota = maildir quota = maildir:ignore=Trash } the problem resides in the quota, when I make: #du - sh /home/muti/Maildir/ 160M /home/michelvf/Maildir/ And in the file /home/muti/Maildir/maildirsize appears: 204800000S 138594655 4180 This doesn't belong together with the real size of the mailbox. That is to say that it is not real, is this normal? or I have not well configured dovecot.conf, I really want that through the file maildirsize, to have control of the quota.

[Dovecot] dovecotpw
by Brent Clark 08 Mar '08

08 Mar '08

Hi I would like to simulate dovecot's dovecotpw with a perl script I tried / used use Crypt::SaltedHash; my $csh = Crypt::SaltedHash->new(algorithm => 'SHA-1'); $csh->add($passwd_string); my $salted = $csh->generate; also use Digest::SHA1; use MIME::Base64; $ctx = Digest::SHA1->new; $ctx->add($passwd_string); $ctx->add('salt'); my $salted = '{SSHA}' . encode_base64($ctx->digest . 'salt' ,''); But it doesnt work. Basically what im doing is authenticating against a mysql db. If i do a dovecotpw -s SSHA -p password and update the DB, then the mail client authenticates perfectly. If anyone can help, it would be most appreciated. Kind Regards Brent Clark

[Dovecot] User another userdb to sasl
by Nicolas Letellier 08 Mar '08

08 Mar '08

Hello, I use Dovecot 1.0.12 with Postfix on FreeBSD. It works perfectly, but I have a question. My users are virtual (stocked in a MySQL database). I use SASL Dovecot authentification, and SASL uses my userdb (for POP/IMAP access). However, I would like my users have an other login/password to send email with SMTP/SASL. Or, I don't want my users use the same login/password for POP/IMAP than SMTP. More, I don't want some users could send emails with their login/password, but I want they can fetch their mails. I'm looking for an option in my dovecot.conf to specifie a table SQL for SASL authentification (and don't use same table SQL than IMAP/POP access). How I could do for this problem? Do you have an idea? Or, simply, is it possible with Dovecot SASL? I read all Dovecot wiki, with no results... Thanks very much. Nicolas

[Dovecot] Building Dovecot with OpenLDAP break PAM LDAP on Solaris
by Laurent Blume 07 Mar '08

07 Mar '08

Hi all, I'm back with more data on a problem Iposted about one month ago. To sum it up, my Solaris 10 box has local accounts as well as LDAP ones via PAM. They work well as-is, with no special configuratio, for WU IMAP (using the «other» entry in pam.conf. When I tried a self-built Dovecot, all accounts were authenticated without problem. Then I tried the Blastwave version, same release, but with more option, and this one didn't work with the exact same configuration: local accounts were authenticated, not the PAM LDAP ones. Now, it turns out that when Dovecot is built using OpenLDAP, then PAM LDAP account won't work. If it's built with Solaris LDAP, they work, everything else being equal. Is there any way to fix that? There's the Blastwave bug report with more details if needed: http://www.blastwave.org/mantis/view_bug_page.php?f_id=0002760 Thanks in advance for any help, Laurent -- / Leader de Projet & Communauté | I'm working, but not speaking for \ G11N http://fr.opensolaris.org | Bull Services http://www.bull.com / FOSUG http://guses.org |

[Dovecot] Squat performance
by Timo Sirainen 07 Mar '08

07 Mar '08

The initial building (and an occational compression) performance just got a major boost. I knew there was a problem there, but I hadn't realized it was this easy to fix: http://hg.dovecot.org/dovecot-1.1/rev/4445415da4ff My 1,4 GB test lkml mbox can be now indexed in 7 minutes, doubling the speed form earlier 14 minutes. I added some more benchmark results here: http://wiki.dovecot.org/Plugins/FTS So the initial Squat index building is about 2-3x slower than the non-indexed search. I think that's pretty good. Also I think it means that the non-indexed search code could be optimized more. :) Maildir test shows that it indexes about 5 MB/CPUsec. My earlier tests showed that it indexed 8-10 MB/CPUs when feeding data directly to it, so 3-5 MB/CPUs is going elsewhere, probably to message parsing and charset conversions and such..

[Dovecot] Upgrading from 0.99.10.5 to 1.1
by Anders 07 Mar '08

07 Mar '08

Hi, I am upgrading a setup from Dovecot 0.99 to 1.1. There are a bunch of .imap.index* files that it appears that I can just delete, and they will be recreated as dovecot.index* files. Right? Next, there are some .customflags that I have now learned are not being converted to dovecot-keywords (as we skipped the 1.0 version, and the conversion code appears to be removed in 1.1). Is there some way to convert this? Is it just a rename? Thanks, Anders.

Hi, I searched whole 2007-2008 mailing lists for answer but couldn\'t find. I think it\'s easier and quicker to ask here. Suppose I have a message saved in file /tmp/afile. How can I tell deliver to deliver it to user\'s abc(a)domain.com mail box SPAM? I tried two following ways but no success: 1. more /tmp/afile | deliver -d abc(a)domain.com -m SPAM 2. deliver -d abc(a)domain.com -m SPAM < /tmp/afile Thank you for help. --------------- Thư điện tử tiếng Việt, đơn giản và thuận tiện: http://mail.vn-mail.net

[Dovecot] Future enhancement of imap: sorting?
by Andy Dills 07 Mar '08

07 Mar '08

After solving a problem with a sweet little application I discovered (more on that below), I wanted to get some feedback about a potential enhancement for IMAP: standardized, MUA independant, server-side sorting. Currently, there are two basic solutions for sorting: handle it during delivery or handle it in the MUA. However, if you handle it in the MUA, you lose some of the client independancy and portability that imap was designed to address, as there is no mechanism to sync sorting rules between clients, and many lightweight clients don't support sorting at all. On the flip side, in distributed mail envrionments sorting at delivery time isn't feasible, as you typically have the entire mailspool owned by a single UID and mounted via NFS. My basic point is that the two paradigms for sorting have fundemental flaws that severaly limit them. It occured to me that it would be ideal to enable sorting in the imap daemon, enabling users to implement sorting rules which are stored in their directory (similar to the other imap metadata), and which get invoked whenever mail is checked. Perhaps that is beyond the reasonable scope of the imap protocol, but in my mind sorting is a critical task that is poorly addressed and needs to be standardized. I'd love to hear opinions on this. See, in our mail cluster environment, it's basically impossible to use procmail without forwarding your mail to our shell server (nor are we able to use the dovecot LDA). So, the question presented to me by one of my business partners was, since Outlook was shortsighted and didn't include the ability to sync sorting rules between clients, nor did they implement sorting functionality whatsoever on the windows mobile version, what options does he have to ensure proper sorting of his mail without having to leave outlook running 24x7? He doesn't want to have to wade through mailing list email on his mobile outlook, nor does he want to have to ensure his filter rules are consistent in both his outlook and our webmail. So, I poked around in the ports tree, and found a gem: imapfilter. http://imapfilter.hellug.gr/ It's configured via lua, supports a very rich array of actions and queries, and has proven to be very robust and lightweight. I helped him get started with some sample rules, added it to run every minute as a cron job, and boom: robust, fully featured, MUA independant filtering in an environment that can't support procmail or the dovecot LDA. As nice as it is, it's still a personal solution. In my mind we need to have standardized, server-side, MUA-independant sorting rules that get invoked when a mailbox is checked. Thoughts?

[Dovecot] Outlook 2003 marks email for deletion
by Jan van den Berg 07 Mar '08

07 Mar '08

Hi, Im running Dovecot 1.1RC1 (only IMAP). I noticed that when I connect with Outlook 2003; and I start reading new email some mails get marked (completely random) for deletion (,S -> ,ST) ?? I can set this mail to unread, undo the deletion read it again and it will stay OK. But other emails will still get marked. This only seems to happen with Outlook 2003 not with Outlook Express or Thunderbird and only with new unread mail. Any ideas why Outlook marks this mail for deletion? Cheers, Jan

[Dovecot] auth_debug_passwords only on mismatches?
by Mike 07 Mar '08

07 Mar '08

>From the configuration notes (1.0.10), it sounds like setting 'auth_debug_passwords' will only log the user supplied password if there was a mismatch.. When I set it (with auth_debug=no), I get a good amount of auth debug info, regardless of password matching.. ------ dovecot.conf: # In case of password mismatches, log the passwords and used scheme so the # problem can be debugged. Requires auth_debug=yes to be set. auth_debug_passwords = yes ------ I'm basically looking to just add a "login failed" line, with the username, and supplied passsword when a mismatch occurs.. Is there currently a way to do this without modifying the code? Thanks! -Mike

[Dovecot] v1.1.rc1 released
by Timo Sirainen 07 Mar '08

07 Mar '08

http://dovecot.org/releases/1.1/rc/dovecot-1.1.rc1.tar.gz http://dovecot.org/releases/1.1/rc/dovecot-1.1.rc1.tar.gz.sig Finally the first v1.1 release candidate. Please test so we can have a fully stable v1.1.0 release. v1.1.betas are already running in a few large installations, so I don't expect there to be many bugs left. There are no release critical bugs left and no known crash bugs. There are a few issues I'd like to fix before v1.1.0, but I don't expect to have more than 3-5 release candidates this time (certainly much less than 31 anyway..) Changes since beta16: - ioloop defaults now to best one availablable instead of poll - IMAP SEARCH correctness fixes - Fixed proxy_maybe handling with caching and with mysql - IMAP: ENVELOPE's subject field now always has TABs changed to spaces - Some crashfixes
