[Dovecot] Can't find next message offset
by Dean Brooks 19 Jun '08

19 Jun '08

Hi, I am getting a lot of warnings since upgrading to 1.1rc10 (from rc4): mbox /home2/seta/Mail/Sent: Can't find next message offset for uid=12 Almost always, it is the Sent or Trash folders that are giving these. Users aren't experiencing any problems, but the errors continue to come. Is this something I should be concerned about?

[Dovecot] Migrate to 1.1 from 1.0.14
by Nicolas Letellier 19 Jun '08

19 Jun '08

Hello. I see dovecot 1.1 will be release very soon. I'm thinking about a migration from my 1.0.14. The migration job will be hard/long? I see in http://wiki.dovecot.org/Upgrading/1.1 that dovecot-uidlist file are in a new format. It will be problem for Courier (pop/imap) upgrades? (today, I often upgrade old mailboxes in Courier to my Dovecot server). Best regards, -- - Nicolas.

[Dovecot] Using checkpassword to block ips?
by Larry Ludwig 19 Jun '08

19 Jun '08

Hi new to the list, but we are a long time user of Dovecot via DirectAdmin control panel. We, like everyone else, are seeing an increase in dictionary attacks of POP/IMAP. We want to block them. I've searched the mailing list and found a few recommended fail2ban, which really won't work for our case. We need to do this over many machines and not one or two. We also like to gather info at the network wide level. Hackers know about attacking specific server/ips too often and we've seen much more distributed attacks that go under the radar of one server monitoring setup. We've designed our own system and use a local RBL to distribute the blocked IPs. For ftp and ssh attacks it's worked very well. We would like to use the RBL to do the same with dovecot. >From my research it appears the best way to do this (and only currently) is with the checkpassword option. I haven't gotten it to work yet. We have: passdb checkpassword { args = /usr/local/bin/checkpassword deny = yes } As the first auth.. This should reject the connection if the IP matches. checkpassword can see TCPREMOTEIP enviornmental variable. In the checkpassword script we have: #!/usr/bin/perl sub read_uinfo { my($user,$passwd,$apop_ts); open X,"<&=3" or exit 111; $_ = <X>; # ugly; should use sysread instead ($user,$passwd,$apop_ts) = /^(.*)\0(.*)\0(.*)\0/; while (<X>) {}; close X; return ($user,$passwd,$apop_ts); } ($user,$passwd,$apop_ts)=$debug?(shift,shift,shift):read_uinfo; $ipaddr=$ENV{TCPREMOTEIP}; $result=system("/usr/sbin/checkdnsbl $ipaddr"); if ( $result == 0) { @ENV{"SHELL","USER","HOME"} = ($shell,$user,$home); exit 0; } else { exit 1; } My questions are as follows: - Can the deny = yes be used with checkpassword? - What am I doing wrong with the script? It should reject only the connections that are in the RBL. It blocks all -L -- Larry Ludwig Empowering Media 1-866-792-0489 x600 Managed and Unmanaged Xen VPSes http://www.hostcube.com/

[Dovecot] quote-warning details
by Alexander Prinsier 19 Jun '08

19 Jun '08

Hello, I have some questions on how quota-warning is supposed to work. -Does it keep a state, so that it doesn't send the same warning several times? Or should the script itself do something to remember it already sent a warning? -When exactly does it run? Does it run when deliver runs? Or only when the user accesses it's mailbox? Thanks, Alexander

[Dovecot] dovecot as gmail imap proxy
by Farkas Levente 18 Jun '08

18 Jun '08

hi, may be this is a bit of topic, but i hope not. it's always a big question which is the better to choose a hosting provider to keep and manage you mail or setup your own mail server, hosting, virus and spam filter etc.. now as more and more people and company move to gmail or google apps mail service it seems google can't handle the load and it's getting more and more slower. what's more not just the imap interface but nowadays the web interface used to be hang or even stop working. it's getting more and more annoying that the speed is worst than in a 10 years ago. i thing about how can this be solved without totally give up gmail as a mail service provider (and may be they can solve it in a few months/years:-). would it be possible to create a dovecot server as an imap proxy for gmail and google apps? imho many people/company would be love to use such a setup where he can use gmail in vacation or any other time, but when the email is real critical apps (not acceptable to wait 1 minutes for an email to load or to open a folder/label) than he can use a proxy server eg. dovecot which act as a imap proxy to gmail and can be hosted on closer, faster server and this speed problem never happend. what's more it can be used as a mail backup server too. anybody has any such setup, idea? would it be possible with dovecot. any other suggestion? yours. -- Levente "Si vis pacem para bellum!"

[Dovecot] don't follow symlinks when creating mailbox list
by Dan Horák 18 Jun '08

18 Jun '08

Hi, this issue was discussed here twice in the not so far history (http://www.dovecot.org/list/dovecot/2008-January/028317.html, http://www.dovecot.org/list/dovecot/2008-February/029147.html) but I need to open it again as it makes problems for our users on one side and on the other side we don't want to diverge from the upstream sources in our packages. I agree with Timo that simply disabling the symlink following in creating the mailbox list can give a false sense of security so the question is whether a permanent solution can be developed and how it should look like?

[Dovecot] Mercurial repositories for ManageSieve and Sieve
by Stephan Bosch 17 Jun '08

17 Jun '08

Hello Dovecot users, Recently I was asked to use Mercurial for the ManageSieve development just like Dovecot. As a matter of fact I have been using Mercurial for some time now. Now that I am back from a short and active vacation I am ready to publish my repositories. The repositories are publicly available at: http://hg.rename-it.nl/ The -patch repositories are so-called Mercurial Queues (MQ) repositories. This provides an easy (quilt-like) means to manage patches over an upstream source repository like the one that exists for Dovecot. The patches are managed in a repository called 'patches' below the .hg directory in your main repository. Currently, these MQ repositories only have the managesieve.patch witch is the actual patch I refresh and release each time Timo makes a new Dovecot release. The following command sequence shows how to incorporate the managesieve patch repository in a freshly cloned dovecot-1.1 tree: hg clone http://hg.dovecot.org/dovecot-1.1 cd dovecot-1.1 hg clone http://hg.rename-it.nl/dovecot-1.1-managesieve-patch .hg/patches hg qpush When updating the dovecot tree it is important to unapply all patches before performing 'hg pull' on the dovecot tree: hg qpop --all hg pull hg update hg qpush This otherwise results in a multi-head situation which can be resolved using a 'hg rollback' or using 'hg qpop --all' afterwards, which should gracefully clean up the situation (never merge the heads!). Updating the patch repository works as follows: hg qpop --all hg -R .hg/patches pull hg -R .hg/patches update hg qpush After 'hg qpush' the dovecot repository is patched and can be compiled as explained for the normal patch method using the .diff.gz (don't forget ./autogen.sh for compiling dovecot in a mercurial repository). The actual ManageSieve implementation for Dovecot-1.1 is available as a separate package and thus there exists a separate repository for it. Its compilation is no different from the .tar.gz releases, except for the fact that (just like for dovecot) ./autogen.sh needs to be executed before configure. The new (and highly experimental) Sieve implementation is available as the dovecot-libsieve repository. It contains a README file that should explain most of its features and the installation procedure. This is currently still not release-ready and should not be used for any important mail whatsoever. I publish this for people who want to test and play around with it to provide feedback on early bugs and (release-critical) missing features. The TODO and README files provide an overview of my current progress towards a first release. Regards, Stephan.

[Dovecot] quota-warning.sh

Hi I have just installed Dovecot (Moved from Courier-IMAP) and have just about everything running well thanks to some great docs in the wiki (Thank you to all those who contributed!) however I have not managed to get the quota warnings working yet. I have done much Googling and come back with some oldish posts which help me to understand how the quota warnings work but having looked at all this I have realised I don't have a quota-warning.sh script in /usr/local/bin where the config suggests it ought to be. In fact, I don't have a file by this name any where on the box. I have downloaded both 1.1 source (Which I'm running) and 1.0 and I can't find this anywhere in the sources or the tarball. Could some one tell me where I can find this or am I supposed to make my own? If so is there and example that I can follow?

[Dovecot] Caseless folder delivery?
by Jay Levitt 16 Jun '08

16 Jun '08

I'm using exim4 to deliver into dovecot 1.1, and using plus-addressing to deliver mailing lists directly to appropriate folders in my "lists" mailbox. I created a file called /folder-map.lists that looks like ## folder-map.lists dovecot: Dovecot lpedge: Linux PowerEdge ... and so on. So mail to lists-lpedge(a)jay.fm goes to the "Linux PowerEdge" folder. The one annoying thing: I'd like to avoid creating explicit folder-map entries where the plus-address suffix is identical an existing folder name. That *almost* works, but I like to name my folders with appropriate capitalization, and deliver doesn't seem to have a way to do "caseless" delivery. For instance, ideally, I wouldn't have to create the "dovecot: Dovecot" entry; mail to my lists-dovecot(a)jay.fm address would go into the "Dovecot" folder. I can't figure out how to do this. Is there a way to do that using deliver? Could there be? Relevant portions of the exim configuration follow. (And, p.s., am I using the new -a and -m options correctly? Are they used for anything yet?)

[Dovecot] Need help configuering Dovecot to support folders that contain sub-folders and messages
by Dan Roberts 14 Jun '08

14 Jun '08

Hi - Last year I set up a new CentOS 5 server and through the install process permitted it to set up dovecot as my IMAP server. ./dovecote --version returns "1.0.rc15" With the system up and running I moved the tar files of my old email accounts over and everything seemed to be just fine. Recently I have upgraded my primary workstation to a Mac Pro - and that of course has it's Mail application. Let me summarize briefly to be sure that I don't omit some minor detail that makes all the difference in the world. Previously I used Netscape 7.2 as my mail client and then went over to Thunderbird on the PC - in either application, under Server Settings / Advanced I had to uncheck the box "Server supports folders that contain sub-folders and messages". Then whenever I attempted to add a new subfolder I would be given a choice - "This server restricts folders to two special kinds. Allow your new folder to contain: [] Folders Only [x] Messages Only". Though perhaps not ideal, this has worked ok up till now. The Leopard Mail application doesn't seem to have this sort of support - it assumes that every folder or subfolder can and should contain both, so all I get are folders that can hold messages. This is a problem as I can't create any new folders to reorganize mail. Though I had thought about resolving this, or at least trying to when I first encountered it - life got busy. So my skills have become a bit rusty and I have not done anything about it. But now I would like to. I ported over my email and my wife's - so perhaps there is some legacy setting in those folders that prevents the bliss of folders and mail in the same subfile. But I created a new email account for my daughter and that has the same limitation. In Leopard mail, folders to hold folders look White, whereas folders to hole mail look blue. In Thunderbird Folders to hold Folders are in Italics whereas Folders to hold mail are normal font. I am also using Webmin to simplify access to the server, but I don't see anything obvious under the dovecot tool for this. The installation was the basic default, so far as I can remember. I have run Yum to update the files and at last review there was nothing outstanding. Regarding my configuration, dovecot -n reports as follows: [root@trailrunner sbin]# ./dovecot --version 1.0.rc15 [root@trailrunner sbin]# ./dovecot -n # /etc/dovecot.conf base_dir: /var/run/dovecot/ protocols: imap imaps listen: disable_plaintext_auth: yes login_dir: /var/run/dovecot//login login_executable: /usr/libexec/dovecot/imap-login mail_extra_groups: mail mail_location: mbox:~/mail:INBOX=/var/mail/%u auth default: passdb: driver: pam userdb: driver: passwd [root@trailrunner sbin]# Truly hoping that someone can help me resolve this. While I can use Thunderbird, I do like the Apple Mail feature of seeing the summary of email at the top of the list. Appreciate the help and insights - Cheers Dan

[Dovecot] Need a quick, safe method to empty /home/user/Maildir/{.Junk, .Trash}
by Jeff Kowalczyk 13 Jun '08

13 Jun '08

I have some (Thunderbird client, dovecot-1.0.13, Maildir) users who get an appalling amount of spam-with-attachment, and it's causing backups to take an inordinate amount of time. I'll implement some quota and server-side spam management when I go to dovecot-1.1, but in the meantime: What is the safest way to empty all messages within, but not delete, the following folders from the server command line: /home/user/Maildir/.Junk /home/user/Maildir/.Trash I don't want the Thunderbird-2.0.14 client to report corrupt indexing, or worse not show the folder at next use. Thanks.

During the conversion, via convert plugin, I get this assertion failure: 2008-06-13 14:12:51 Error: IMAP(username): Next message unexpectedly lost from 4700 2008-06-13 14:12:51 Error: IMAP(username): Next message unexpectedly lost from 4700 2008-06-13 14:12:51 Panic: IMAP(username): file istream-crlf.c: line 49 (i_stream_crlf_read_common): assertion failed: (size != 0) 2008-06-13 14:12:51 Error: IMAP(username): Raw backtrace: imap [0x80d1c31] -> imap [0x80d1c9a] -> imap [0x80d159c] -> imap [0x80d6fa5] -> imap [0x80d6fc3] -> imap [0x80d81b9] -> imap(i_stream_read_data+0x39) [0x80d60f9] -> imap [0x80cadb3] -> imap [0x80cbdeb] -> imap(message_parser_parse_next_block+0x1d) [0x80cae5d] -> imap(index_mail_cache_parse_continue+0x22) [0x8096132] -> imap(maildir_save_continue+0x4b) [0x807a49b] -> imap(mail_storage_copy+0xdb) [0x80a07ab] -> imap(maildir_copy+0x5b) [0x8076ebb] -> /usr/lib/dovecot/modules/imap/lib20_convert_plugin.so(convert_storage+0x48c) [0xb7f279bc] -> /usr/lib/dovecot/modules/imap/lib20_convert_plugin.so [0xb7f2841d] -> imap(mail_namespaces_init+0x645) [0x80a1345] -> imap(main+0x3c1) [0x806ab51] -> /lib/libc.so.6(__libc_start_main+0xe0) [0xb7e02450] -> imap [0x805ca91] 2008-06-13 14:12:54 Error: IMAP(username): Mailbox conversion: Couldn't create mailbox directory Ospedale 2008-06-13 14:12:54 Fatal: IMAP(username): Mailbox conversion failed, exiting If it can be useful for debugging purpose, is there something I can do to identify the mailbox causing the failure? I am also investigating why the plugin tried to recreate directory for the already converted mailbox "Ospedale". -- Marco De Benedetto

[Dovecot] 9GB of messages in /tmp
by Charles Marcus 13 Jun '08

13 Jun '08

Hello, Well, I have a brain-dead user (using Thunderbird 2.0.0.14) who just won't listen when I tell them not to try to move 5000+ messages at one time (or if deleting, bypass the Trash), and they managed to royally screw up their maildirs... I have two problems... 1. The /tmp directory has 9+GB in it... can I just rm tmp/* on that directory without making this problem worse? and 2. One of the directories they were moving now has 5 copies of a whole bunch of messages... I'm very dangerous when it comes to command-line work beyond really basic stuff, and my scripting skills are less than inspiring... Is there a relatively safe command-line way of finding all messages that have more than one instance, and deleting all but the last instance? Tia... -- Best regards, Charles

Helo all, I'm working on a migration from qmail+courier+maildrop to postfix +dovecot1.1+lda and today the logs has too many strange messages like this: Jun 12 10:51:22 mailserver03 dovecot: IMAP(xxxxl(a)xxxx.com.br): Broken file /data/services/dominios/xx.com.br/m/ma/mapel//Maildir/.Sent/dovecot-uidlist line 29: UID larger than next_uid (535 >= 535) Jun 12 10:51:26 mailserver03 dovecot: POP3(xxxx(a)xxxxx.com.br): Broken file /data/services/dominios/bx.com.br/n/no/nordeste//Maildir/dovecot-uidlist line 2: UID larger than next_uid (12 >= 12) Should I worry about this?

[Dovecot] "Disable non webmail IMAP access" in vpopmail and Dovecot
by Alessio Cecchi 13 Jun '08

13 Jun '08

Hello, i'm using in my installation qmail+vpopmail and now I have migrated from courier-imap to dovecot. Dovecot is very much faster with large mailbox than courier-imap. But I have a problem. vpopmail has a feature that allows you to "Disable non webmail IMAP access", many webmail using imap as if they were, and they are, a client IMAP. vpopmail give me the ability to disabile IMAP, expect for 127.0.0.1, both for individual users than for single domain. So i can grant IMAP access, from remote client, only for some users but webmail access for all. Here you can read some of my messages in the vpopmail's list: http://www.mail-archive.com/vchkpw@inter7.com/msg25880.html But with dovecot this feature seems not to be compatible. A friend of the vpopmail's list sent me a patch for dovecot but I can not get it to work: >->->->->->->->->->->->->->->->->->->->->->->->->->-> Hi Alessio, i spent over 5 hours looking for a solution to this problem and i found one working for me in dovecot sources edit src/auth/passdb-vpopmail.c than add char *remotehost = net_ip2addr(&auth_request->remote_ip); auth_request_log_info(auth_request, "vpopmail", "remote ip is: %s", remotehost); before if (((vpw->pw_gid & NO_IMAP) != 0 && line than modify the condition line to look like: if (((vpw->pw_gid & NO_IMAP) != 0 && strcmp(auth_request->service, "IMAP") == 0 *&& strcmp(remotehost, "127.0.0.1") != 0*) || ((vpw->pw_gid & NO_POP) != 0 && strcmp(auth_request->service, "POP3") == 0)) { auth_request_log_info(auth_request, "vpopmail", "%s disabled", auth_request->service); password = NULL; *result_r = PASSDB_RESULT_USER_DISABLED; } else ............... this way you will preserve webmail access and cut imap from external in case -i limit is defined in vpopmail hope it helps <-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-< Can someone help me in making compatible this useful feature of vpopmail with dovecot?

[Dovecot] configure error on HP-UX: C99 compatible vsnprintf() call
by Woonsan Ko 13 Jun '08

13 Jun '08

Hi All, I tried to build dovecot-1.1.rc9 on a HP-UX machine, but failed to configure with the following message: configure: error: You don't appear to have C99 compatible vsnprintf() call The environment is like the following: - command: ./configure - uname: HP-UX B.11.23 U ia64 - aCC version: HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003] Also, I tried to run `./configure CC=c99' and `./configure CC="/opt/aCC/bin/aCC -Ae" also, but the result was the same. I'm not sure, but the HP C compiler does not seem to support C99 fully with vsnprintf() call. Is there any workaround for this problem? TIA, Woonsan
