[Dovecot] Dovecot SSL issues
by Spyros Tsiolis 29 Jan '10

29 Jan '10

Hello all, successfully managed to make dovecot work with horde (http://www.horde.org) and another MTA (SMTP/POP3). I have this nagging issue with dovecot though (I suspect - it's dovecot and not the rest of the packages, please read on): There is this special page one goes, that check if everything is ok with all the relevant software running along Horde. It's a php file called "test.php". Now, this file shows almost everything that happens in the box. Here's a transcript of what shows when it comes to dovecot and SSL : --------------------------- * Trying protocol imap/ssl, Port 993: ERROR - The server returned the following error message: SECURITY PROBLEM: insecure server advertised AUTH=PLAINCertificate failure for localhost: self signed certificate: /C=GR/ST=Kerkyra/L=Kerkyra/O=The Company Name/OU=IMAP server/CN=webmail.thecompanyname.gr/emailAddress=postmaster(a)webmail.thecompanyname.gr --------------------------- From what I understand, it doesn't like the certificate. However, I've followed a howto document step-by-step and did what is documented. Does anyone have any pointers on how to make secure imap for dovecot ? E.G. on ThunderBird, the settings are the following : Tools -> Account Settings -> Server Settings : Server Name : (the server or its ip address) Username : (the username) Port : (I've manually entered "993", because by default goes to "143") Security Settings -> Connection Security : SSL/TLS (again manually entered) CHECK_ON : Use secure authentication Now, if I click on "Get Mail" button on top of the TB window, I get a pop-up window with the following message : ------ Server : Location : <Servers' IP Address>:993 Certificate Status : This site attempts to identify itself with invalid information. Wrong Site : Certificate belongs to a different site, which could indicate an identity theft. Unknown Identity : Certificate is not trusted, because it hasn't been verified by a recognized authority. ------ After that, the users accepts the above by pressing ok twice. However, there's a third pop-up window with a message shown below : ------ You cannot log in to <servers' ip address> because you have enabled secure authentication and this serer does not support it. To log in, turn off secure authentication for this account. ------ Any help would be appreciated.. Thank you all for your patience, S. Tsiolis

[Dovecot] mdbox, dsync
by Timo Sirainen 29 Jan '10

29 Jan '10

I finally migrated my mails from mbox format to mdbox format using dsync: 1. Stop dovecot, wait a few seconds for processes to die 2. dsync convert mdbox:~/mdbox 3. Change mail_location to mdbox:~/mdbox 4. Check that no new mails arrived during conversion (alternatively I could have just run dsync again, but I decided not to test my luck) 5. Start dovecot After fixing a pretty bad bug in dsync and a couple of other unrelated bugs, everything seemed to work correctly and transparently. UIDs and everything was preserved as expected. I think I even feel my mail clients being faster than with mbox :) ~% du --exclude=.imap -bsh mail-old-mbox 707M mail-old-mbox ~% du -bsh mdbox/* 27M mdbox/mailboxes 704M mdbox/storage The reason why I'm giving -b is because without it, mdbox was a lot larger than mbox (734 MB vs. 710 MB). I guess this is because zfs internally decided to waste some space for the files. ~/mdbox/storage% ls -lS -rw------- 1 tss tss 13602413 2010-01-29 18:05 m.68 -rw------- 1 tss tss 10487382 2010-01-29 18:06 m.209 -rw------- 1 tss tss 7749964 2010-01-29 18:06 m.270 -rw------- 1 tss tss 7493010 2010-01-29 18:05 m.69 .. -rw------- 1 tss tss 2097246 2010-01-29 18:06 m.175 -rw------- 1 tss tss 2097213 2010-01-29 18:06 m.151 -rw------- 1 tss tss 2097173 2010-01-29 18:06 m.197 -rw------- 1 tss tss 2097163 2010-01-29 18:05 m.89 -rw------- 1 tss tss 1307164 2010-01-29 18:33 m.296 Total of 296 files. The reason why there are a few large files is because their last mail is huge. I guess in future mdbox should try to avoid doing that if it knows the mail's size beforehand. Actually I thought it already tried to do that.. Anyway, let's hope it doesn't now corrupt all my mails.

[Dovecot] dovecot auth feature request
by Frank Cusack 29 Jan '10

29 Jan '10

when i try to run dovecot for SASL support only, with literally just this configuration: protocols = none ssl = no auth default { mechanisms = plain login passdb passwd-file { args = /etc/dovecot/passwd } socket listen { client { path = /var/spool/postfix/private/auth mode = 0660 } } } I get this: Error: ssl_cert_file: Can't use /etc/ssl/certs/dovecot.pem: No such file or directory Since, in this configuration, SSL doesn't have meaning, dovecot shouldn't be looking for any cert file. Easily fixed with "ssl = no" but that shouldn't be required. -frank

[Dovecot] mailbox format w/ separate headers/data
by Frank Cusack 29 Jan '10

29 Jan '10

In the future, it would be cool if there were a mailbox format (dbox2?) where mail headers and each mime part were stored in separate files. This would enable the zfs dedup feature to be used to maximum benefit. In the zfs filesystem, there is a dedup feature which stores only 1 copy of duplicate blocks. In a normal mail file, the headers will be different for each recipient and the chances of the content of the message being able to be dedup'd are close to zero, because the differences in header length changes the block boundaries for the rest of the message. But if each mime part is stored in a separate file, you get massive compression "for free". -frank

[Dovecot] Courier-to-Dovecot-migration: Outlook downloads all Mails again
by Werner 29 Jan '10

29 Jan '10

Hi everybody, I'm currently playing through the migration from Courier to dovecot. I've converted the User's Maildir with 'courier-dovecot-migrate.pl'. Outlook 2003 is configured to access the Mailbox via POP3, the option "Leave a copy of messages on the server" is activated. But: after the migration Outlook 2000 redownloads all mails again :-( Could it be, that Outlook 2000 "thinks" (after changing the POP3/SMTP-Server in the Outlook configuration pointing to my testsystem) this is a new system and starts to download the messages again? If so, Outlook 2000 won't download all messages again if we do the migration because POP3/SMTP-Server remains the same. Can anybody confirm this? We do not experience this issue with Thunderbird for example. Thank you, Werner

[Dovecot] virtual users with mysql
by Andre Hübner 28 Jan '10

28 Jan '10

Hello List, we use in our system cryptical Usernames for dovecot etc. and authenticate users against shadow/passwd User abcde is loging in and gets data from /var/spool/mail/abcde and /home/popuser/abcde Now we want to make it possible that users can log in also with emailadresses. I tried dovecot-mysql authentication which works fine but i do not find a way to use 2 different login-formats in my queries. login with abcde and also testname(a)example.com should return ok and lead to /var/spool/mail/abcde. Is this possible or i have to make a decision which format to use? Thanks, Andre

by Kirill Miazine 28 Jan '10

28 Jan '10

Just a notice to those of you who use Dovecot authentication with Exim. In Dovecot 2.0 authentication server will send a new keyword, COOKIE. This will cause Exim to abort it's authentication request. I submitted a bug and patch to Exim to fix this, the patch is here: http://km.krot.org/code/exim-dovecot-1.1.diff BR, Kirill

[Dovecot] virtual mailbox / INTHREAD use case, issues, questions
by David Abrahams 27 Jan '10

27 Jan '10

For over a year now, I've been trying to acquire the ability to review the thread history of a message in my INBOX while still deleting messages as soon as I believe I'm done with them. Suddenly I'm gratified to see that several approaches have been right under my nose all along! One is the INTHREAD imap extension, which I see is implemented by dovecot. Another (related) is dovecot's virtual folders. When I saw the GMail-style "conversation view" described at http://wiki.dovecot.org/Plugins/Virtual I was elated, so I tried it out, with exactly that configuration (almost -- my separator is '.'). I ran into several problems (using Dovecot 1.2.8 with http://hg.dovecot.org/dovecot-1.2/rev/9cccb8617820 applied): 1. I had to manually create the virtual folder for all my users or they couldn't access their mail at all. Is this fixed in 2.0? 2. My users were getting errors when accessing via POP3. The possible meaning of such a virtual folder under POP3 is lost on me, but I had to enable the virtual plugin for that protocol too. I think that should at least be in the documentation, or better yet the requirement should that it be enabled for POP3 should be dropped. 3. I couldn't get the virtual "conversation view" inbox to show any messages. But maybe that's because of a possible issue I describe below with x-mailbox 4. At some point I ended up with an empty mailbox called "private.virtual" --- I have no idea how. Probably user error. 5. The "all" virtual mailbox would only show 89 messages. I switched it to be a mirror of my "archive" mailbox and the number started to look more reasonable. This could be the "lots of mailboxes" bug describe in http://dovecot.org/list/dovecot-news/2009-December/000145.html 6. I got the impression that looking at the virtual INBOX didn't cause the "all" mailbox to be updated, which I'd guess that it should be. 7. I tried to create an IMAP search, rather than a virtual folder, that looked for x-mailbox INBOX header like the virtual folder does. It too came up empty. It doesn't exactly surprise me because I don't see an x-mailbox header in any of these messages. In fact, I can't find one in /any/ of my messages. When I look for a description of the x-mailbox header, I don't find much information on where it comes from or what it represents. http://www.dovecot.org/list/dovecot/2009-June/040619.html seems to indicate it's synthesized by the server. If it's really supposed to represent the message's "original" mailbox as implied by http://wiki.dovecot.org/Plugins/Virtual then I'm not sure what that means for messages that are filed twice by sieve and never moved. Lastly, I want to report that for me, the speed of these IMAP searches doesn't begin to approach what I can do with mairix if I want a message's entire thread. I'm happy to use mairix, although it would be nicer not to duplicate that capability if it's already in the server. But it needs to be fast. Is there something I can do to make it go faster? Thanks in advance for any advice, hints, fixes, workarounds, etc. -- Dave Abrahams Meet me at BoostCon: http://www.boostcon.com BoostPro Computing http://www.boostpro.com

Looks like my bugfix exposed yet another bug. Your script worked previously because the removeflag command did not work properly. With 0.1.15 I fixed the removeflag command, thus breaking your script. The essence of the bug we face now is that for the deprecated imapflags extension (that you are using now) only the flag state at the end of the script is used for storing messages. This is now fixed: http://hg.rename-it.nl/dovecot-1.2-sieve/rev/a890258aa5a9 You can work around this issue by substituting "imapflags" with "imap4flags" in the script above. I've added some proper tests to the test suite to prevent this problem from re-occuring in the future. Regards, Stephan.

[Dovecot] STATUS command and total/read message count
by Florian Effenberger 27 Jan '10

27 Jan '10

Hello, I'm running Dovecot 1.0.15 with Thunderbird 3.0.1. TB can query folders for messages in two ways: Either by using the STATUS command, or by opening the folder (don't know the respective IMAP commands, sorry...). Querying via opening the folder is reliable, but via the STATUS command, only new/unread messages are shown. If I want to have the total number of (unread) mesages in a folder, I have to manually open it, so the headers are loaded. Is this a Dovecot issue, or a problem with Thunderbird? In other words: Does the STATUS command only return new/unread messages, or can this be configured on the server side? Thanks, Florian

[Dovecot] Plugin
by Alex Baule 27 Jan '10

27 Jan '10

Hello Everyone... Some time ago, i send some questions about plugins and concat 2 file handles. So, there is another questions about this. Timo Sirainen send to me this modification, in src/lib-storage/index/maildir/maildir-mail.c struct istream *full_input[3]; full_input[0] = i_stream_create_fd(fd, 0, TRUE); full_input[1] = i_stream_create_fd(fd1, 0, TRUE); full_input[2] = NULL; input = i_stream_create_concat(full_ input); This is necessary because my Header and Body is splited. This modification works fine. My question is: There is a way to do this with a plugin ? I dont know how to implement this in a plugin, because i dont know what is the hook to change the maildir_open_mail functions. (this is the function with the modification above) . Another question is: There is a seek function, in dovecot, and in zlib plugin, it is rewrite by another function, that use the "gzseek" to do the seek. My splited body will be encrypted, and the crypto no have seek, because the message will be encrypted. (if i open the message, decrypt and seek to some position, maybe work). The seek function is really necessary to IMAP and maildir ?

Hi ALL... I want to know if the files in /Maildir/cur & /Maildir/.Sent are modified by dovecot. I have a script which calculates the age of the mail files. I think that if they are continuously modified by dovecot I won't be able to calculate the age of the files. Can Anyone plz advise on this....

[Dovecot] read-only dovecot-uidlist
by Cor Bosman 26 Jan '10

26 Jan '10

Hi all, i just investigated a user complaint and found a read-only dovecot-uidlist. Since dovecot couldnt write it, the process failed. Users can not reach this file, so how this became readonly is beyond me. Must be something in dovecot. Maybe an older bug? Doing a search now for more readonly uidlist files, but that'll take a few hours. Cor

[Dovecot] dovecot-antispam for dovecot 2.0?
by Adam Seering 26 Jan '10

26 Jan '10

Hi, Just wondering, is there a development version or the like of the dovecot-antispam plugin, that works with the Dovecot 2.0 beta? I'm starting to poke at the new version (mdbox looks really handy for my use case); I'm also starting to play with dspam, but I'm finding it annoying to train dspam without it having direct access to my (rather-large existing) spam folder... Thanks, Adam

Hi ALL... Am working on a solution to backup maildir mailboxes using rsync. All mailbox directories are mirrored on another machine. I need advise regarding restore of the INBOX & SENT files from the backup. For e.g , [1] Can I just copy "file-x-y-z" from /Maildir/cur to restore it on /Maildir/cur on the mailserver. [2] Can I do same for SENT emails ?

[Dovecot] acl flag to limit imap_acl based acl changes
by Amon Ott 26 Jan '10

26 Jan '10

Hi all! I have tried the imap_acl plugin with 1.2.9 today, but was not able to limit acl changes for those mailboxes where acl changes should be forbidden. http://wiki.dovecot.org/ACL says that "a" or "admin" covers "Administration rights to the mailbox". However, removing "a" from owner acl (using "lr") does not help, the user can still change all acl flags for all users with imap. Write accesses to mails are forbidden as they should. Is this intended or a bug? We would like to give all users the ability to use ACLs through IMAP, but the current behaviour endangers our read-only mail archives.
