[Dovecot] Maildir and home location
by Florian Lindner 10 Oct '13

10 Oct '13

Hello! My current mail setup looks like that: MTA is postfix, MDA is maildrop. Each system user configures mail delivery using the .mailfilter of maildrop to arbitrary maildirs in his home. For each maildir a POP3/IMAP account can be configured, currently I use courier-imap/-pop and think about replacing it by dovecot. AFAIK with dovecot each account has a home and maildir assigned which should not be equal neither should a home dir be used for mulitple accounts. My problem is where to put these homedirs? System users have full SSH access on the machine. I would really prefer to put them somewhere where the users could delete them (if they need to reset or delete their account). Optimal would be in the maildir itself, but... What are your suggestions? Regards, Florian

[Dovecot] v2.2: Fix to slow process creation in some setups
by Timo Sirainen 10 Oct '13

10 Oct '13

Especially some imap/pop3 login bursts could have caused errors like: imap-login: Error: net_connect_unix(imap) failed: Resource temporarily unavailable Fix in http://hg.dovecot.org/dovecot-2.2/rev/69179ca6007d Explanation & workaround in http://wiki2.dovecot.org/SocketUnavailable : Dovecot v2.2.0 - v2.2.6 were attempting to optimize host.domain lookups by doing them only once in the master process. Unfortunately they were actually doing the lookup every time when creating a new process. In some configuration this lookup could have done a somewhat slow DNS lookup, causing the process creation to become very slow and triggering this message. The fix is in v2.2.7 and you can also workaround this: • Add to dovecof.conf: import_environment = TZ DEBUG_OUTOFMEM DOVECOT_HOSTDOMAIN • Before "dovecot" binary is started, run: export DOVECOT_HOSTDOMAIN=mailserver.example.com (of course changing the value)

[Dovecot] smartsieve managesieve-login failure with dovecot 2.1.7
by Wouter Berkepeis 09 Oct '13

09 Oct '13

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, I just subscribed to the mailing list because I am stuck trying to solve a problem getting smartsieve to work with a new version of dovecot. But let me first explain the situation shortly. I am running a mail server at home for personal use, and for fun. At this moment this is an old, slow machine running Debian Squeeze, Dovecot 1.2.15 and Exim 4.72. Authentication is done with LDAP, running OpenLDAP 2.4.23. For managing mail filtering I use Smartsieve 1.0.0-RC2 in conjunction with Dovecot's Managesieve plugin. It's all working properly. But because this machine is slow, I'm now busy upgrading building a new machine running Debian Wheezy, Dovecot 2.1.7 and Exim 4.80. I've got it all running and working now (that is: locally in my lan): imap with dovecot, smtp with exim, Dovecot's sieve plugin working properly, authentication done through LDAP backend. But what I can't get to work is Smartsieve. Looking at the logs on my server I can tell managesieve-login is not working well with Smartsieve. As far as I understand authentication is always done over a secure connection using TLS. Here is some logged output, Dovecot as well as Smartsieve. dovecot-info.log: 2013-10-06 21:16:20 managesieve-login: Info: Disconnected (no auth attempts in 0 secs): user=<>, rip=127.0.0.1, lip=127.0.0.1, TLS handshaking: SSL_accept() failed: error:14094410:SSL routines:SSL3_READ_BYTES:sslv3 alert handshake failure: SSL alert number 40, session=<NkXdXhfodwB/AAAB> syslog: Oct 6 21:51:40 jingo smartsieve[12168]: getCryptLib: using rc4 Oct 6 21:51:40 jingo smartsieve[12168]: getCryptLib: using rc4 Oct 6 21:51:40 jingo smartsieve[12168]: FAILED LOGIN: jingo [192.168.2.12] {Private Lotus}: starttls: TLS initialization failed: socket timed out while reading server response: #002 Oct 6 21:51:40 jingo smartsieve[12168]: 2Z#027#015141003200542Z0??1#0130#011#006#003U#004#006#023#002NL1#0230#021#006#003U#004#010#014#012Overijssel1#0200#016#006#003U#004#007#014#007Hengelo1#0!#006#003U#004#012#014#032Private Lotus Organization1#0230#021#006#003U#004#013#014#012Jingo Mail1&0$#006#003U#004#003#014#035jingo.private-lotus.no-ip.net1&0$#006#011*?H?÷#015#001#011#001#026#027amigo(a)private-lotus.org0?#001"0#015#006#011*?H?÷#015#001#001#001#005 Oct 6 21:51:40 jingo smartsieve[12168]: #003#001 Oct 6 21:51:40 jingo smartsieve[12168]: èm¬NþgHÁßt#021×?Ð#011$?f+»#013?#021?ø#013yùZd#032Òí}Ì#012ù?#003xPË What is clear is that somehow no user information is being negotiated.

[Dovecot] POP3 Setup help
by Thomas I Higgins 09 Oct '13

09 Oct '13

I am lost as to what I am missing. I am setting up dovecot 2.0.9 on a RHEL 6.4 machine as provided by my provider. I have IMAP up and running, and I have POP3 up and running. Testing confirms this. Also, if it makes a difference, I enabled dovecot as my LDA. Sendmail was setup as well due to our 1.x version using it and I though I had to. Anyway, everything is working perfectly with the services, except the mail is sending to the wrong location for POP. I am trying to use Maildir for both services, but it keeps delivering the POP3 mail to /var/spool/mail/u% instead of to Maildir as specified in the configuration files. I have rechecked every setting at least twice and still can't see what I am doing wrong. I suppose I can use mbox and redirect after making the appropriate namespace changes, but that has it's own potential drawbacks and seems more like a kludge than the correct way around this (unless I misunderstand how it should work). Can anyone point me in the right direction on how to fix this? Thanks in advance, Thomas Higgins

Hi everybody. Hi I'm tryingto use CAS for authenticating in dovecot. I have installed pam_cas and when I try castest i get "<cas:authenticationSuccess>" for my service (imaps://mywebmail.com) But when I actually try to login, dovecot uses the PT from the cas server as password. Any ideas what I'm missing? Thanks a lot.

Looking at http://wiki2.dovecot.org/PasswordDatabase/ExtraFields/Proxy methinks you want to replace "starttls=y" with "ssl=yes". Joseph Tam <jtam.home(a)gmail.com>

Hi, I've been trying to build a password forwarding proxy to Gmail without success... The SSL connection to Dovecot is happening no problem (as far as I can tell), but for some reason the conversation between Dovecot and Gmail is getting timed out. I know this is supposed to be simple... :-( But could somebody please give me some help by pointing what I'm not doing right? No matter how much I've been researching about this, I can't find the solution.

[Dovecot] Replication: long detalys
by Lucas Rothamel - Eye Catching Webdesign 07 Oct '13

07 Oct '13

Hello everybody, I am running dovecot 2.1.7 on Debian Wheezy on two servers with replication set up, MTA is postfix. The idea is to have a redundant mail system so that when one server fails, users can continue using the other server (failover of POP/IMAP through DNS redirection). Servers are called srv06 and srv07: Below is the dovecot config, both servers have identical config, only the replica srv0x address is different. I read to put this line into 10-mail.conf and I did: mail_plugins = $mail_plugins notify replication My Problem: When E-Mail arrives on one server, it is only available on the other server many hours later. Same behaviour in both directions. This means I see different mailboxes via IMAP depending on which server I connect to - in theory I want the client not to be able to tell which server it is connected to. dovecot -n: # 2.1.7:

[Dovecot] retr errors
by Bill Morgan 07 Oct '13

07 Oct '13

My ISP uses Dovecot and I have had an ongoing problem for a while using several email clients. Sometimes the response to a retr request is mal-formed. The expected response "+OK nnn octets" is not returned. The response looks like it started somewhere in the message headers. Sometimes a retry can clear the problem but I usually need to delete the first message via a putty session. The problem, when present, is always on the first message. Never seen it in the middle of a series of messages. This problem has been seen on different machines, different versions of Windows, at home and on the road. I have wireshark traces showing good and bad sessions.... ====================== stat +OK 93 1000437 retr 1 +OK 6946 octets Return-path: ..... ========================= retr 1 of blahblah(a)blah.com designates 2607:f8b0:4001:c03::235 as permitted sender) smtp.mail=blahblah(a)blah.com; dkim=pass header.i=(a)blah.com Reply-To: android-developers(a)googlegroups.com Precedence: list Mailing-list: ...... ================== My ISP has been non-helpful. Any ideas how I can track down the problem? Thanks Bill

[Dovecot] Yet another going from 1.2 to 2.X question: authentication
by Mauricio Tavares 07 Oct '13

07 Oct '13

So in 1.2.9 I had something like this: [...] socket listen { master { path = /var/run/dovecot/auth-master mode = 0600 user = virtual # User running Dovecot LDA's deliver } } # Dovecot as SASL Auth socket listen { client { path = /var/spool/postfix/private/dovecot-auth mode = 0660 user = postfix group = postfix } } I see I can, per http://wiki2.dovecot.org/HowTo/PostfixAndDovecotSASL, setup the sasl entry as # Dovecot as SASL Auth service auth { unix_listener /var/spool/postfix/private/dovecot-auth mode = 0660 user = postfix group = postfix } what about the lda? From http://wiki2.dovecot.org/LDA I take it would be as simple as service auth { unix_listener auth-userdb { mode = 0600 user = virtual # User running Dovecot LDA's deliver } } Am I correct?

I have stood up a new test mail server as an upgraded version of my existing mail server. I have been fairly consistently getting two types of error messages.

[Dovecot] Problems getting Squirrelmail and Avelsieve to connect to Pigeonhole

[Dovecot] State of the FTS modules and packaging
by Benjamin Podszun 06 Oct '13

06 Oct '13

Hi there. I'm running a small (VPS) mail system just for myself for quite a while and want to support some friends and family now. For that I'm improving / documenting the setup. One thing I never cared to implement was FTS support. Looking at the options [1] now, I'm stuck. I don't want solr (no Java bashing here, I'm sure that's working awesome. But I don't want to pull all these dependencies in on my tiny VPS: Memory and disk will be as small as I can get away with). With that out of the way: What are my options? Squat: Why's squat deprecated? Did it stop working? Can someone shed some light on the original reasons for the deprecation? What are the risks to go with squat anyway? Clucene: That seems .. unusable. It would be my prefered choice (not deprecated, little dependencies), but .. it isn't packaged in deb based distributions (Debian, Ubuntu). It doesn't even _build_, because it doesn't use pkg-config to find the clucene includes (at least for 2.1.17) in these environments. Centos is even more out of date with 2.0.9. Given the experience above, is solr my only option to offer FTS? Can you guys share how you're having a stable base/os with a somewhat recent (and complete!) dovecot package? Thanks a lot & regards, Ben 1: http://wiki2.dovecot.org/Plugins/FTS

[Dovecot] Dovecot namespace solved while writing; preparing to refilter
by miro.rovis＠croatiafidelis.hr 06 Oct '13

06 Oct '13

Since I still have to send mail from web, I may not be able to get this message as a reply to my previous mail, but it belongs to this same thread: http://www.dovecot.org/list/dovecot/2013-October/092810.html Some of the work I have now done. I can now easily, lest some hurdle shows up, use a script based on the one I mentioned (here it is again: http://wiki.dovecot.org/HowTo/RefilterMail ), but I used maildrop, having harkened to the advice by the author of Debian Reference, Osamu Aoki: http://www.debian.org/doc/manuals/debian-reference/ch06.en.html#_the_remote… http://www.debian.org/doc/manuals/debian-reference/ch06.en.html#_mail_deliv… So while, after connecting with the password, I wait some 5 or 10 minutes (the machines I install/clone Debian onto are old machines) for all the mail from the other Dovecot on the other machine, same MBO and all, as I explained in the previous message, again; I am preparing this before going online, I haven't see if there are any replies in the last maybe 40 hours)... me@mybox2:~$ getmail getmail version 4.43.0 Copyright (C) 1998-2012 Charles Cazabon.

But I hope this will be technical enough now and to the completion of this thread...

I meant zucky Facebookmail. Also it would be great to check for existance of a foled before attemting to create it... It hasn't been yet urgent to me, and I am rather exhausted now, not only from this coding, but also because I got the tumbleweed pollen allergy (American native plant, brought here as ornamental plant in Columbo's time, but nauseating/suffocating (but rarely to death), fever causing to lots of people in Europe, through allergy, so I was also bed-ridden much of the time... and I am not well neither as I am writing this, so not much of proofreading before sending this.

I also have a few issues probably for the Mutt people to solve, the issues I suspect are with Mutt, but they are not urgent either. And also, not major issue, I tried sticking :DIRNAME=mAildir to the end of my mail_location line, but it simply didn't work, I mean, as per: http://wiki2.dovecot.org/MailLocation/Maildir I will try and get the stunnel to get my outgoing mail on the 465 port with TLS, but that is not an issue related here at all I think. Thanks again to you fine developers for these great programs. Timo Sirainen, you are greatly appreciated here, and my respect for your fine country Finland, and for your nation!

[Dovecot] Fixing Timestamps
by LuKreme 05 Oct '13

05 Oct '13

I have a user with a lot of email (A LOT of email, probably over 500,000 emails). Recently, several thousand messages of his were lost, and I pulled them out of the backup archives (zip files containing each days emails in an mbox) that are created on his account and fed them into his procmail scripts and they were all processed just fine and ended up in the right directories. Except. The messages were from 6 months back, and the messages now show up in his mail client with the time stamp of the date they were restored, and not the date that shows up in the headers of the message. Anything I can do? -- I AM NOT A LICENSED HAIRSTYLIST Bart chalkboard Ep. AABF04

[Dovecot] On mailboxes, separators, and dovecot2
by Mauricio Tavares 04 Oct '13

04 Oct '13

While I was running dovecot 1.2.9, I had my mailboxes using the old Courier IMAP format. i.e. my mailboxes would look like INBOX.Orders.Scams Going to dovecot 2 (but not 2.1), I see to have a few questions: 1) It seems I would device my mailbox thingies in 10-mail.conf: namespace inbox { inbox = yes separator = . location = prefix = INBOX. type = private mailbox SPAM { auto=subscribe special_use = \Junk } mailbox Trash { auto=subscribe special_use = \Trash } mailbox Sent { auto=subscribe special_use = \Sent } } but how would I prepresent my INBOX.Orders.Scams folder? Something like mailbox Orders.Scams { auto=subscribe } perhaps? 2) Reading (am I literate?) through http://wiki2.dovecot.org/Namespaces, it seems having separator = . is not only outdated but also a bad idea (but, I had child mailboxes as shown above). Could anybody elaborate one that? And which clients still do LSUB *?

[Dovecot] Can sieve filter mail based on emails earlier in the thread?
by Hugh Davenport 03 Oct '13

03 Oct '13

Basically I want the following scenario: Subscribe to lots of mailing lists - each filtered into separate folders When I participate in a thread (by starting it, replying to it, or ... setting a flag on an email in the thread) - filter into the particular mailing list folder - AND filter into INBOX (or another folder of my choosing) I'm thinking for this, the first two can have rules that take into account In-Reference-To and using my domain. But the third case of using a flag... that seems to require referencing earlier emails in the thread. Is this possible in sieve? Or am I barking up the wrong tree? I believe gmail can do it, but who knows what they use for their filtering... Thanks for any help anyone provides! Cheers, Hugh

[Dovecot] Proxy to gmail help

[Dovecot] How to configure statistics tracking
by Bruce Marriner 03 Oct '13

03 Oct '13

I'm trying to configure the dovecot statistics tracking option with Dovecot 2.1.12 on FreeBSD 9.1-RELEASE. I've seen on the wiki page the configuration settings needed for this but it does not say which configuration file these settings should be added to. http://wiki2.dovecot.org/Statistics I was hoping someone could tell me which file these settings should be added to? Do they all just go into the same file or different files? I have a primary dovecot.conf file then inside conf.d/ there are dozens of files that hold the configuration settings for all the different parts of dovecot. Would I just add all of these settings into a conf.d/stats.conf file that would be pulled into the main configuration? Does it matter what order the (10-stats.conf, 20-stats.conf, etc) the file is set for? Thanks.

[Dovecot] Username issue with Dovecot LDA, IMAP and Winbind Authentication
by Laz Peterson 03 Oct '13

03 Oct '13

Hi there Dovecot community -- I'll try to make this short. Here's the setup … Ubuntu 12.04, Postfix, Dovecot, along with Amavis/Clamd/Spamassassin. Postfix is currently receiving emails for virtual users in multiple domains, all of which are authenticating through Winbind to Windows AD servers. The users log in to the POP/IMAP/SMTP services using the format user(a)domain.corp (the internal domain, not the external mail domain). The domains are all in the same forest, but there are many different domains to authenticate against. Dovecot is currently handling POP, IMAP, and authentication. Postfix uses a MySQL database to map the external email domain to the internal AD domain, for example domain.com -> domain.corp. Postfix also queries the same SQL database for where to save the messages -- /home/vmail/domain\user -- I have the SQL query strip off the ".corp". I had to do this because pam_winbind returns the usernames as "DOMAIN\user" upon successful Dovecot authentication, instead of "user(a)domain.corp", which ends up invalidating all of the %u, %n, and %d variables. On the user side, after successful auth, I can only define %u and %n in my Dovecot configuration -- %d is null, %u is "DOMAIN\user", and %n is "DOMAIN\user". (I use %Lu or %Ln to make it all lower-case.) With this, I am able to authenticate users off of multiple domains, have the mail delivered to a folder that is also accessible to the user when they log in. It serves its purpose. Here's my problem. I am trying to now integrate Pigeonhole and ManageSieve using Dovecot-LDA specified by "virtual_transport", and this is where things get confusing. Dovecot IMAP/POP/SMTP auth notes the user account to be "DOMAIN\user", while Dovecot-LDA receives the email to user(a)domain.com, noting the user account to be "user(a)domain.corp". The same arguments for userdb in "auth-system.conf.ext" are used by both Dovecot when user is logging in for IMAP/POP/SMTP and Dovecot-LDA when it is storing the mail. Because of the way pam_winbind returns the usernames without being able to use %d anymore, I cannot seem to get the same behavior for both sides of Dovecot. For example, if I set home and maildir to "/home/vmail/%Ln", Dovecot-LDA delivers emails into the folder "/home/vmail/user(a)domain.corp" and Dovecot IMAP/POP looks in "/home/vmail/domain\user". If I set the home/maildir to "/home/vmail/%Ld/%Lu", Dovecot-LDA delivers emails into the folder "/home/vmail/domain.corp/user" and Dovecot IMAP/POP looks in "/home/vmail/\/domain\user". So, I seem to be thoroughly unable to get something here that works … The closest I can get is setting home/maildir to "/home/vmail/%Ld\%Lu", but that now gives the LDA side "/home/vmail/domain.corp\user" and the IMAP/POP/SMTP side "/home/vmail/\\domain\user". If I am able to get pam_winbind to return "user(a)domain.corp" instead of "DOMAIN\user", I'd be fine. Or, if I could set the home and maildir locations separately for Dovecot-LDA and Dovecot, I would also be okay. Any suggestions? I know this is probably a Winbind limitation, but I do not know a thing about working with PAM authentication. I tried to compile and install a pam_regex module (which seems to not be offered as a native package in Ubuntu), but it gives errors after adding that to my PAM configuration. I'm stumped. Please let me know if I can include my configuration for either Postfix or Dovecot. Thank you so much for any help. ~ Laz Peterson

[Dovecot] understanding user_attrs and mail_uid/gid
by Vincent Zakofski 03 Oct '13

03 Oct '13

Hello, I'm trying to understand what's the difference between those parameters. In my dovecot.conf in the global section I have a definition of mail_uid and mail_gid. In my LDAP configuration used by passdb and userdb, I have a definition for user_attrs= uidNumber=500,gidNumber=8. Here is a part of my configuration files (dovecot version: 2.1.7) dovecot.conf mail_gid = 8 mail_uid = 500 passdb { args = /etc/dovecot/dovecot-ldap.conf driver = ldap } userdb { args = /etc/dovecot/dovecot-ldap.conf driver = ldap } dovecot-ldap.conf user_filter = (&(objectClass=posixAccount)(mailLocalAddress=%n)) user_attrs = uidNumber=500,gidNumber=8 So everything works fine when all those parameters are present in my configuration files. If I suppress one of them nothing is working (mail reading or delivering). Can someone tell me where I can find a definition of those arguments, if found nothing relevant on the wiki. Thanks,

Hello, i've setup sieve script which send notify to user (user(a)domain.com) But user(a)domain.com is alias user(a)domain.com and user(a)anotherdomain.com. LMTP delivers notification only to user(a)domain.com but not to user(a)anotherdomain.com. How to force send notification over smtp (which will be delivered to both) or i must use to=user(a)anotherdomain.com in notify ? Thank you for your advices. Lampa

[Dovecot] Dovecot namespace solved while writing; preparing to refilter
by miro.rovis＠croatiafidelis.hr 02 Oct '13

02 Oct '13

Hi! My plea to readers: =================== Pls., people who only want strictly technical issues to read, and frown at any broader context regardless how intrinsically related, but not strictly technically related, it might be, skip all the way, all the way to, search for exact words: "strictly technical" or visually, find two lines of sole "===" characters. Thank you! Upon umptieth failure, and having cloned the system onto another same arch, much more: same MBO-model box (cloning and restoring clean is my defence to get the system into as clean a state as can be, after any longer time online --I had had systems comprimised, and now I am a little paranoid)... So, after weeks of some failures in some phases of installations of dovecot and friends (as explained further in this text), I cloned the same system, but from previously taken clean backup, used it some time, and now I want to update the mailbox back because now the first system is in clean state, having I restored from clean backup... This is a Debian weekly testing install, which I clone btwn two same MBO-model boxes to keep it as clean as a non-expert user like me can have it... To a large extent I do trust installing and update/upgrading my systems from the weekly builds (but hey, why don't they PGP-sign those as kernel tarballs and as Grsecurity or Tor-browser tarballs are signed? any Debian developer reading this, why not?)... because I can check with some trust the weekly builds' sums for integrity, but how and why could or would I trust simply installing anything straight from the internet? By cloning (I used to dd disk dump when cloning, but nowadays it seems faster and reliable enough with Sysresccd's fsarchiver, so I dd just the small boot partition), by cloning I keep the system as close to clean as those non-pgp-signed weekly builds allow... Now add to that that the real FFmpeg is not allowed into Debian, and I am a fan of it (I very much use it, it's running almost all the time, on some or other of my systems), but you have to get it through deb-multimedia.org if you want it on Debian (what freedom is that, banning programs from official repositories?!)... and add to that that I want Grsecurity/Pax at all cost, in my system, and not: http://www.nsa.gov/research/selinux/ which I don't want in my system, at all cost, but to which the Debian current leadership seems to be total-blind-fidelity bound to... Add those and you get pretty much all the basic ingredients of my fight for freedom and true privacy which are layed siege onto in the GNU/Linux Operating System and the few related other free OS's, in most of its flavors and branches and deployments of the day, from the outside and also from the inside. Because even with the long-delayed-in-updating gNewSense, for insufficient developer power (I mean: too few), probably, what's the use of the fine deblobbed kernel if they put SELinux into it? Where's freedom with what I suspect can not be other than fake security with surreptitious surveillance? (BTW, go and ask people, but not loudly, who compile their Gentoo's --there' a link to my short post on forums.gentoo.org a few lines below-- like I compile (on other systems of mine), only a minority of very uninformed or some special entities' aficionados use anything other than Grsecurity on their Hardened Gentoos --and Gentoo is unquestionably the leader in hardening-- it's not just me, it's only that I am loud about it)... But I also tried to call this issue to GNU-freedom seeking people's attention such as here: https://lists.nongnu.org/archive/html/gnewsense-users/2013-09/msg00001.html and entire thread: Grsecurity on gNewSense, but for real? I didn't mean to dwell on these issues here, and it is not the reason I write my messege to dovecot-mailing list, but this is the broad perspective of my, and I am sure not only my case, of my deployment of dovecot and broadly these are the reasons why I deploy it on my system. No, this broader picture I don't think is not off-topic. I did think hard about it... No, I believe it is good to mention these issues in this post-Snowden era when the scale and scope of total surveillance can not be successfully sneered and scoffed at and dismissed, like some "exceptional" (Obama talking to the U.S. of A. nation in September 2013, in his quest for support, thankfully lacking, of then being planned Iraq-2003-like-in-pretence-and-lies attack-to-be on Syria)... like some "exceptional" people would want it (that's the Gentoo Forum's link mentioned above)... http://forums.gentoo.org/viewtopic-t-967806.html A case of actual protection of my Gentoo box by Grsecurity At least these issues should not be anymore successfully sneered and scoffed at and dismissed, but we're all less and less free as mankind... And, since I don't connect to my SOHO network the box which I open to the internet, I have mails to refilter into the very probably clean cloned box... And I need to refilter using dovecot (which I finally got to work)... These lines, all the dozen or so paragraphs from the beginning up unto here, do appear first for reading, but are written just about all the very last, after the rest of the text below has already been written, except the final proofreading notes intersparsed). ============================================================================= ============================================================================= Now nearly only strictly technical I go, for the sake of people who prefer so. That maildir mailbox being all poorly sorted (I must have made other mistakes, I am just still new and generally lack expertise in all these true mailer tools; but very impressed I am with them! thanks Sirainen, thanks Varshavchik, thanks MuttDude, thanks Venema, and all, I admire you people!), so I removed the old Maildir and I made this scriptlet: This is my configuration: me@mybox:# dovecot -n # 2.1.17: /etc/dovecot/dovecot.conf # OS: Linux 3.10.9-grsec-130827 x86_64 Debian jessie/sid auth_debug = yes mail_debug = yes mail_location = maildir:~/Maildir:LAYOUT=fs mail_plugins = acl quota mail_privileged_group = mail namespace { hidden = yes inbox = yes list = no location = mbox:~/mail:INBOX=/var/mail/%u prefix = "#mbox/" separator = / } namespace { location = maildir:~/Maildir prefix = separator = / } passdb { args = dovecot driver = pam } protocols = " imap" ssl_cert = </etc/dovecot/dovecot.pem ssl_key = </etc/dovecot/private/dovecot.pem userdb { driver = passwd } protocol imap { mail_plugins = acl quota imap_acl imap_quota mail_log notify } me@mybox:# cd ~ maildirmake Maildir maildirmake -f Drafts Maildir/ maildirmake -f Sent Maildir/ maildirmake -f someFolder1 Maildir/ maildirmake -f someFolder2 Maildir/ maildirmake -f someFolder2.Facebk Maildir/ One note: pls. don't get me wrong, I hate Stasibook (Facebk above is less typing, but it's for Facebook mail), I just would like to learn enough to teach and get at least some of my friends who "socialize" there out of reach of those stasi-like entities that Zuck and his Gang serve all the "socializing" users' data to, which is so hard a task for me to do, but which desire keeps me moving in this steep-learning-curve quest of mine that got me this far where I am now, with dovecot and other tools. That is the reason I am still subscribed there, to be able to follow what my people do, occasionally. I'm not logging into that walled-off sewage-like stasi hole featuring as virtual garden! I saved that scriplet as maildirmake_00.sh, then $ chmod 755 maildirmake_00.sh and ran it. me@mybox:~$ ./maildirmake_00.sh And I have, I guess so far, all correct: me@mybox:~$ ls -la Maildir/ total 40 drwx------ 10 mr mr 4096 Oct 1 23:06 . drwxr-xr-x 33 mr mr 4096 Oct 1 23:06 .. drwx------ 2 mr mr 4096 Oct 1 23:06 cur drwx------ 5 mr mr 4096 Oct 1 23:06 .Drafts drwx------ 5 mr mr 4096 Oct 1 23:06 .someFolder1 drwx------ 5 mr mr 4096 Oct 1 23:06 .someFolder2 drwx------ 5 mr mr 4096 Oct 1 23:06 .someFolder2.Facebk drwx------ 2 mr mr 4096 Oct 1 23:06 new drwx------ 5 mr mr 4096 Oct 1 23:06 .Sent drwx------ 2 mr mr 4096 Oct 1 23:06 tmp me@mybox:~$ I really hope no mistake I made so far. someFolder1 and someFolder2 are for two different servers I get my mail from. Will probably need to tell some more about them later if the thread develops, when the problems I have are more fully explained/solved/expanded. Now the dovecot. It has, in Debian, and I'm on weekly testing branch, currently up to date, actually last week's, that's just a little behind... It has 15-mailboxes.conf like this (only pasting non-commented lines), /etc/dovecot/conf.d/15-mailboxes.conf namespace inbox { mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Trash { special_use = \Trash } mailbox Sent { special_use = \Sent } } [ here is a time lapse of cca 5-10 hours ] Well, since I began writing, I realized that I can get the namespace to work properly, but exactly only without the above: /etc/dovecot/conf.d/15-mailboxes.conf (I mean with all the lines above commented out) It kept telling me this (in the logs I find): Error: user me: Initialization failed: namespace configuration error: Duplicate namespace prefix Let me first say that it's I finally got closer to solution, and saw directories with mutt as ~/Maildir/this/that instead of what maildirs are: ~/Maildir/.this.that only after getting the following in the 10-mail.conf /etc/dovecot/conf.d/10-mail.conf: mail_location = maildir:~/Maildir:LAYOUT=fs mail_plugins = acl quota namespace { separator = / location = mbox:~/mail:INBOX=/var/mail/%u inbox = yes hidden = yes list = no } namespace { separator = / prefix = location = maildir:~/Maildir } It's what is recommended in <Namespaces.txt> on the wiki and maybe other places. But only after the 15-mailboxes.conf was completely commented out. Now I can view my mailbox from anywhere on my network, I guess (tried from the other box and from the same box with mutt, it works!). So namespace is solved I guess. However, for my mail system to completely function in the right GNU/Linux way, I have to get more GNU good things together in harmony. Naming some of the other dovecot friends: *getmail*, which hands on to *maildrop* for delivery... And *postfix* with TLS for sending mail, via 465 port, *stunnel*... That bit feels daunting to me, really... This namespace thing also cost me a few ounces of raw nerves and some occasional darkness in feelings... The worse is still before my mind constantly: still not being able to send mail the normal way, since the normal way is simply not in cleartext anymore... I probably could just fine sent to port 25, but after all the political persecution and censorship that as homeland-living dissident I suffered and still suffer, I don't see that as a solution at all... The obscured morale that I was upon me for a while is due to that stunnel connection not being yet set up... So, sending this from the web yet, I guess (prepared upfront, jealous of my time fixing systems that suffer from strange behavior or break whenever I'm longer online)... However, since I have been writing this not really hoping to get the namespace working in the process (quite a few days I spent on it, and weeks on mail system altogether, I can only hope to get the stunnel right if I really study it as if attending university classes, I'm afraid, just like the hurdles that I went finally past cost me real studying your manuals, my GNU freedom heros!)... ...And this message I having had started some five or ten hours ago [ before the final broader picture paragraphs that are all in the beginning part of the message; this very note is at the time of the very last proofreading ], now I see that I went different direction before discovering the setup for namespace that worked for me. How I used maildirmake (it's the maildrop's not the dovecot's one) I thought but now see doesn't probably have much to do with the solution for namespace I found. I leave it there though, because I need to fix the mailbox by refiltering it, with the aid of the dovecot server, similar to how it is explained in: http://wiki.dovecot.org/HowTo/RefilterMail Because I got some syntax wrong in ~/.mailfiler for the maildrop MDA, and then I got some of those wrongly named (numbered, no a-z, only 0-9 digits in names) fake mailing-list folders that can be seen in my post on mutt mailing-list: http://marc.info/?l=mutt-users&m=138021971816188&w=2 (the .muttrc however is completely different now, sure, than in that link) I hope the main, the namespace dovecot part of this message may elicit someone's advice, if they got past that phase with the 15-mailboxes.conf at its default. Or it is explained in the manuals I need to give a second or a third read to understand them... And I'll be back to report if I made ordered mails in my Maildir right with the refiltering. Just pls. allow time, I'm a late adopter, I'm 56 years of age, can't make these things as quick as you youngsters do it. Thanks for the fine Dovecot mail server! Miroslav Rovis Zagreb, Croatia

[Dovecot] LDAP for passdb and SQL for userdb
by Bambero 02 Oct '13

02 Oct '13

Hello Is it possible to setup double backend ? ldap for auth only and SQL for userdb information(quota,maildir etc) ? Now I'm using SQL backend and configuration looks like this: passdb { driver = sql args = /etc/dovecot/dovecot-sql.conf } userdb { driver = prefetch } userdb { driver = sql args = /etc/dovecot/dovecot-sql.conf } Can I do something like: passdb { driver = sql args = /etc/dovecot/dovecot-ldap.conf } userdb { driver = prefetch } userdb { driver = sql args = /etc/dovecot/dovecot-sql.conf } Should I leave: userdb { driver = prefetch } Bambero

[Dovecot] Older messages not showing up after reinstall
by dclist 02 Oct '13

02 Oct '13

I reinstalled Ubuntu, keeping my maildir directories. Messages older than the date of reinstall are not being served by dovecot. The messages show up normally in my MUA if I load the maildir directory directly. I assume there is a file somewhere where dovecot is keeping a list of seen messages which I need to reset. The old messages appear to be in dovecot-uidlist. I tried moving dovecot.index* to no effect. How do I get the pre-reinstall messages to be served by dovecot? # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.8.0-31-generic x86_64 Ubuntu 13.04 auth_debug = yes auth_debug_passwords = yes log_timestamp = "%Y-%m-%d %H:%M:%S " mail_debug = yes mail_location = mbox:~/mail:INBOX=/var/mail/%u mail_privileged_group = mail namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { args = /etc/dovecot/password driver = passwd-file } passdb { driver = pam } plugin { fts = squat fts_squat = partial=4 full=4 } protocols = imap service auth { user = root } ssl_cert = </etc/dovecot/dovecot.pem ssl_key = </etc/dovecot/private/dovecot.pem userdb { args = uid=vmail gid=vmail home=/home/vmail/%u driver = static } userdb { driver = passwd } protocol imap { mail_plugins = fts fts_squat } protocol pop3 { pop3_uidl_format = %08Xu%08Xv }

[Dovecot] Dovecot disconnecting while downloading large attachments
by Marc Casas - Girotec 01 Oct '13

01 Oct '13

Hi, We're using Dovecot 1.2.15 with Debian Squeeze. The mail server is working properly (we use both POP3 and IMAP) with normal messages, but if we try to download a large message (more than 20mb) using POP3, the server disconnects and our application fails. It's possible to change this behavior? How can we setup Dovecot so it disconnects after 20 or 30 minutes (I think now is disconnecting after 10 minutes) of "inactivity"? Regards, Marc

[Dovecot] Panic: file mail-storage.c: line 834 (mailbox_verify_name): assertion failed
by Kamil Andrusz 01 Oct '13

Hello List! I've encountered an error after upgrading my system and dovecot. I guess it's probably a result of a configuration problem, however after quite some tinkering with configuration I am still missing the source of the problem. Sep 28 16:57:21 shwurzbung dovecot: imap(wizz): Panic: file mail-storage.c: line 834 (mailbox_verify_name): assertion failed: (strncmp(vname, ns->prefix, ns->prefix_len-1) == 0) Sep 28 16:57:21 shwurzbung dovecot: imap(wizz): Fatal: master: service(imap): child 23203 killed with signal 6 (core not dumped - set service imap { drop_priv_before_exec=yes }) The problem above appears with both dovecot 2.2.5 and 2.2.6. It did not happen while using dovecot 2.1.12. Operating system is OpenBSD 5.4-current and AMD64. FS type is FFS (default for OpenBSD).

[Dovecot] New install not working.
by Rhorer, Leslie 30 Sep '13

30 Sep '13

Hello. I need some help. I was running uw-imap on my IMAP server (so I am using mbox email files), but I was having trouble with Outlook 2013, so I decided to move to dovecot. At first things were looking much better, except that most of my folders, other than the Inbox, were not showing up. I started changing both the dovecot configuration and the folder structure of my mail files, but now I can't even get the Inbox to populate. Outlooks says it is there, along with any folders I create new in Outlook, plus the Trash folder, which is the only non-local folder with anything in it. Try what I might, I can't get my Inbox to populate or any of the existing folders to show up at all. Here is the current output from dovecot -n: # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-4-amd64 x86_64 Debian 7.1 xfs mail_location = mbox:/RAID/home/%u/mail namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { driver = pam } protocols = " imap pop3" ssl_cert = </etc/dovecot/dovecot.pem ssl_key = </etc/dovecot/private/dovecot.pem userdb { driver = passwd } I have the mail files on a RAID array (separate from the boot arrays) at /RAID/home/<User>/mail.

[Dovecot] Using MailDir but local messages still save in mbox format
by Mike Edwards 30 Sep '13

30 Sep '13

I am using MailDir format for all my virtual users and it is working well. However, if email comes in to a unix system user, it delivers in Mbox format. This is mostly cron jobs that do this. Mail addressed to my virtual users goes to the MailDir locations just fine. None of these mailboxes have ever been created, they are just incorrect assumed addresses. There should NEVER be any email to username(a)my.host.name because everything is virtual. Does anyone know how to fix this? Here is my config. # 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-358.18.1.el6.x86_64 x86_64 CentOS release 6.4 (Final) auth_debug = yes auth_mechanisms = plain login cram-md5 ntlm auth_verbose = yes auth_verbose_passwords = plain disable_plaintext_auth = no listen = * mail_location = maildir:~/Maildir mail_privileged_group = mail managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date mbox_write_locks = fcntl passdb { args = /etc/dovecot/conf.d/dovecot-sql.conf.ext driver = sql } plugin { autocreate = Trash autocreate2 = Spam autocreate3 = Drafts autocreate4 = Sent autocreate5 = Archives autosubscribe = Trash autosubscribe2 = Spam autosubscribe3 = Drafts autosubscribe4 = Sent autosubscrube5 = Archives sieve = ~/.dovecot.sieve sieve_before = /home/vmail/movespam.sieve sieve_dir = ~/sieve } protocols = imap pop3 service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-master { mode = 0600 user = vmail } } ssl_ca = /etc/pki/dovecot/ca/dovecot.pem ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem ssl_cipher_list = HIGH:MEDIUM:+TLSv1:!SSLv2:+SSLv3 userdb { args = uid=vmail gid=vmail home=/home/vmail/%d/%n driver = static } protocol lda { auth_socket_path = /var/run/dovecot/auth-master log_path = /home/vmail/dovecot-deliver.log mail_plugins = " sieve sieve" postmaster_address = postmaster(a)zeus.deltatechnicalservices.com } protocol lmtp { mail_plugins = " sieve" } protocol imap { mail_plugins = autocreate } protocol sieve { managesieve_implementation_string = Dovecot Pigeonhole } protocol pop3 { pop3_uidl_format = %08Xu%08Xv }

[Dovecot] pop3-login problem
by Oleksii Krykun 30 Sep '13

Hi! I have dovecot-2.2.5 installed as part of postfix+dovecot+mysql+amavisd. My server has two NICs (Internet and local). /etc/resolv.conf point to ISP DNS. Local names are not resolved. If ISP link goes to down state I see (after about 1minute) a following error: Sep 26 15:44:29 pop3-login: Error: master(pop3): Auth request timed out (received 0/12 bytes) and following informational message: Sep 26 15:44:29 pop3-login: Info: Internal login failure (pid=12809 id=17815) (internal failure, 1 successful auths): user=<xxx(a)xxx.xxx> ..... If link is restored (even for a short time) all works fine again. After next down errors are repeated. I suppose that this is dns issue. Am I wrong? And I have a following question. Is it possible to disable dns requests? I haven't external clients. Or I must fix a name resolution e.g. to use a caching dns server? Thanks.

[Dovecot] proxy: can I use the password returned from passdb to log in to the back-end?
by Justin McAleer 30 Sep '13

30 Sep '13

I am hoping to support encrypted passwords, which I know is generally not allowed in a proxy setup. However, I can return the password in clear-text out of the password database, so I was hoping for something similar to the destuser field. I have successfully used the master password functionality to support encrypted passwords (users impersonating themselves), as long as the back-end server supports that. However, I need to proxy POP3 to Gmail, which does not.

[Dovecot] Processing sent items
by Bruce Markey 29 Sep '13

29 Sep '13

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 How does dovecot handle sent items and is it possible to "process" them befor they get saved in the sent item folder? My scenario is that I'm running postifx + dovecot with all incoming and outgoing mail passed to a script that encrypts the mail with the public key of the recipient. The only place now that has unencrypted mail sitting on the server is the sent items, I'd like to fix that. What would be the best way to proceed here? - -- Encrypt everything. Public key: https://www.secryption.com/BruceMarkey.asc I believe that any violation of privacy is nothing good.

[Dovecot] How to authenticate against SQL DB with custom-ciphered passwords?
by Nicolay Vizovitin 29 Sep '13

29 Sep '13

Hello, I'm about to start developing authentication/password-scheme module for Dovecot. So I would like to get some advice before actually committing to doing things in particular way. Hope somebody will be able to help me :) For the record, I am currently targeting latest stable Dovecot version 2.2.5. I have an SQL DB with mail users' authentication data. Passwords are stored either encrypted via system crypt(3) or ciphered with some custom algorithm (think something symmetrical like AES, so passwords can be decrypted into plain form). I want to use this DB as both userdb and passdb backend. The issue, of course, is with ciphered passwords support. 1) Is it feasible to just implement a new password scheme for ciphered passwords support and still use stock passdb driver in Dovecot for SQL DB access? So that passwords in this scheme would be treated as PLAIN (in a sense that both cleartext and shared secret authentication methods would work). 2) Provided I implement custom password scheme for ciphered passwords, what is the best way to be capable to perform authentication against both ciphered and encrypted passwords? Ciphered and encrypted passwords are stored in different fields of SQL table (one of them is NULL when the other one is set). a) Do I define two passdb clauses with their own default_pass_scheme (equal to my new scheme or CRYPT for encrypted passwords) and use fallback to effectively check both of them? b) Do I modify SQL query so that it prefixes existing password with correct scheme (I'm not sure this will be easy enough to do)? 3) Is it mandatory to provide password generation routine for custom password scheme? When it will be used? 4) Maybe it's better to just implement a plugin that serves as both userdb and passdb driver (in other words a kind of generic authentication module)? What are advantages and disadvantages of each method - custom password scheme + stock SQL driver VS. custom userdb and passdb driver? Fortunately, I already have all the required credentials lookup and verification code. So in any case the question is only in figuring out suitable Dovecot APIs and integrating the existing code. 5) I have previously implemented similar custom authentication module for Courier-IMAP (Courier-Authlib to be precise) to use the same SQL DB. And I will need to support both IMAP servers for some time. So it is only natural to expect some generic solution to be possible. I'd like to remind that I need to be able to supply either encrypted password or deciphered plain password, or just check against them. Is it possible to do so in a common way? If so, what method should I use? I would expect SASL helping me out here, but AFAIK, both Dovecot and Courier-IMAP can only serve as SASL servers (providing authentication services), not clients. 6) I obviously care about providing enhanced security, especially against stealing mail passwords. So any additional advice or related guidelines are welcome. 7) Somewhat unrelated question: what is the best way to test IMAP (and maybe POP3 as well) server performance and compare it to another server? I'm interested in both login performance (the part I will influence) and performance with many mails in mailbox. I heard imaptest is suitable for this task. Are there any recipes or example testing scenarios you might share? ;) I would be grateful for any insight in these issues. If I chose a wrong mailing list to post to, please feel free to correct me. Thanks for your time! :) -- Best regards, Nick

[Dovecot] Released Pigeonhole v0.4.2 for Dovecot v2.2.6 and Pigeonhole v0.3.6 for Dovecot v2.1.17.
by Stephan Bosch 27 Sep '13

27 Sep '13

Hello Dovecot users, Now that Dovecot v2.2.6 is released, I can release a new Pigeonhole. Due to the SO_REUSEPORT changes in Dovecot, this Pigeonhole release will not compile cleanly against older Dovecot releases. This release is mainly about bugfixes. I also made a new release for Dovecot v2.1.17 that includes most of these fixes and some older ones. A word of warning for people using doveadm sync in combination with sieve: make sure you update both sides of the replication to avoid problems after upgrade. The attribute sub-tree under which Sieve scripts are replicated has moved to a different root. Since we expect that very few people are affected, there is no facility for backwards compatibility. This is no problem as long as both sides are upgraded. There is one new feature for the Sieve vacation extension. Normally vacation replies are sent with <> sender to prevent mail loops. A setting is provided to override this behavior (doc/extensions/vacation.txt), as requested on the mailing list. This is not a violation of the specification, but use this with care. Changelog v0.4.2: * Incompatible change in Sieve doveadm plugin: the root attribute for Sieve scripts is changed. Make sure that you update both sides of a dsync setup simultaneously when Sieve is involved, otherwise synchronization will likely fail. + Added support for sending Sieve vacation replies with an actual sender, rather than the default <> sender. Check the updated doc/extensions/vacation.txt for more information. - Fixed a binary code read problem in the `set' command of the Sieve variables extension. Using the set command with a modifier and an empty string value would cause code corruption problems while running the script. - Various fixes for doveadm-sieve plugin, mostly crashes. These include a fix for the `Invalid value for default sieve attribute' problem. - Various fixes for compiler and static analyzer warnings, e.g. as reported by CLang and on 32 bit systems. - Fixed the implementation of the new :options flag for the Sieve include extension. - Fixed potential segfault bug at deinitialization of the lda-sieve plugin. - Fixed messed up hex output for sieve-dump tool. Changelog v0.3.6: - Fixed a binary code read problem in the `set' command of the Sieve variables extension. Using the set command with a modifier and an empty string value would cause code corruption problems while running the script. - Various fixes for compiler and static analyzer warnings, as reported by CLang. - ManageSieve: Fixed '[' ']' stupidity for response codes (only happened before login). - Fixed setting name in example-config/conf.d/20-managesieve.conf. - Fixed messed up hex output for sieve-dump tool. The releases are available as follows: http://www.rename-it.nl/dovecot/2.2/dovecot-2.2-pigeonhole-0.4.2.tar.gz http://www.rename-it.nl/dovecot/2.2/dovecot-2.2-pigeonhole-0.4.2.tar.gz.sig http://www.rename-it.nl/dovecot/2.1/dovecot-2.1-pigeonhole-0.3.6.tar.gz http://www.rename-it.nl/dovecot/2.1/dovecot-2.1-pigeonhole-0.3.6.tar.gz.sig Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information. Have fun testing this new release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

[Dovecot] Strange errors with imapc+acl in 2.2.x
by René Neumann 27 Sep '13

27 Sep '13

Hi, after migrating to 2.2 (currently using 2.2.5), I see strange error messages when using imapc + public namespace + acl My setup: I create a public shared mailbox with imapc as location. Then I restrict this mailbox to one user only using ACLs. This works for this one special user, but for all others an error gets logged and they can't access their mailbox anymore: Sep 24 18:09:46 [dovecot] imap(other(a)my.domain): Error: user other(a)my.domain: Initialization failed: Namespace 'Gemeinsam.': Ambiguous mail location setting, don't know what to do with it: yes (try prefixing it with mbox: or maildir:) Sep 24 18:09:46 [dovecot] imap(other(a)my.domain): Error: Invalid user settings. Refer to server log for more information. My config (relevant parts): ------------------ Dovecot conf ---------------- imapc_host = some_host imapc_port = 143 imapc_user = some_user imapc_password = some3$pwd imapc_ssl = starttls imapc_ssl_verify = no namespace gemeinsam { type = public separator = . location = imapc: prefix = Gemeinsam. subscriptions = no } # I also tried different combinations of hidden and list plugin { acl = vfile:/etc/dovecot/global-acls:cache_secs=300 } ------------- /etc/dovecot/global-acls/Gemeinsam ------- anyone user=special(a)my.domain lrwstipekxa -------------------------------------------------------- Does anyone have any thoughts about this?

[Dovecot] Dovecot extremely slow!
by Patricio Rojo 27 Sep '13

27 Sep '13

Please help, Dovecot is running extremely slow for the last couple of weeks and it seems to be getting worse (or my patience running short). I attach the 10-master configuration and the log file after running strace according to: http://wiki.dovecot.org/Debugging/ProcessTracing I can click on an email and wait for a minute or more before receiving a connection dropped or no error at all. I use many clients (thunderbird, windows 8 mail, maildroid for android, squirrelmail) and they all have similar behavior. It happens both in the inbox and on imap subfolders. Sometimes it helps changing subfolders back and forth. I have many imap folders organized in up to 3 levels of subfolders and use postfix for delivery. Let me know any other info you require. Thanks!

[Dovecot] Courier migration and vpopmail with dovecot-lda
by Charles Sprickman 27 Sep '13

27 Sep '13

I've been using Dovecot in some fresh installs lately and have found it fairly easy to configure. However I'm starting on a migration that involves moving from some very old software (ancient vpopmail, qmail and Courier). On the Courier front, I've reviewed the migration page in the wiki, and it looks like the main concerns are just matching the namespace and then using the migration script to create new subscription and uidlist files. Given that my Courier IMAP setup is so old (4.0.6), is there anything to be aware of that's not covered in the wiki due to the age of Courier here? Are there any other general issues to be aware of as far as interactions with MUAs are concerned? For example, if Courier has been presenting the user's MUA with a given set of IMAP capabilities and then the MUA sees a bunch of extra capabilities on a subsequent login, will that trigger any strange behavior? And lastly on this subject, I will obviously be doing some testing before cutting over to the other server. Is it valid in something like Thunderbird to have it pointed to "imap.domain.com" and then change the imap server to point to something like "testimap.domain.com" for testing whether subscriptions and the uidlists are working as expected or should I fully replicate the move as an end user would see it by making the change in my local hosts file? Now, assuming that portion of the move goes alright, I'm incredibly confused about getting Dovecot and Vpopmail working together. I assume that initially I can stick with the Maildir++ mailbox format and let vpopmail's vdelivermail continue working as my LDA - vdelivermail understands how to find the user's Maildir, it can check quotas, and it can update the maildirsize file (which I'm assuming dovecot can also read and then report quota/usage to an IMAP client). However it does look like the Dovecot-only mailbox format(s) will offer much better performance than Maildir as the two dbox formats are the only supported mailbox formats with separate index files, correct? Is there any guidance on how to use dovecot's LDA with a virtual mail system such as vpopmail? From what I've read so far, I probably don't want to use the vpopmail extension supplied with dovecot, but query the mysql vpopmail db directly. I'm finding a ton of info while searching for this, but most deals with older versions of dovecot, and there are also many "this works but I don't know why" tutorials on combining dovecot and vpopmail and dovecot's own LDA. I'm not even able to guess how one handles the per-user .qmail files in vpopmail if not using vdelivermail (this is where we enable/disable spam filtering by piping the message through spamc). Any input on the overall migration process is appreciated. It's a bit overwhelming as I have to deal with a big jump in the vpopmail version, rebuilding qmail with a ridiculous number of patches, and then on top of that a migration to new imap/pop server software. eek.

managesieve has gone mad. One person went on holiday when he came back his out of office would not switch off, then it replicated it's self into two other users (the vacation noticE) and started to be sent out for them and those users had never set up an out of office or looted into round cube. even deleting the vacation notice did not stop it, but if we put another vacation notice in then the new one is sent out, if we disable the new one then the old one is sent out…. mad…. how can I refresh the whole thing and start again… ? I am running this on 10.8.4 mountain lion server and I can't stop sieve… I have looked in the /Library/Server/Mail/Data/rules/USERFOLDER and removed all sieve files I have looked in each users mailbox but no seve files there… I have restarted and still sieve will not stop sending out emails…. yesterday it went crazy sending a mail a second from one mailbox back to it's self…. help….. osx 10.8 server using latest roundcube with managesieve plugin.... bash-3.2# ps -aef|grep dovecot 0 27481 1 0 12:07am ??

[Dovecot] Grant access for Unix-User _and_ virtual Users
by marco 26 Sep '13

26 Sep '13

Hi group, I have installed a postfix as an MTA and configured two "main" domains as well as two virtual mailbox domains. Normal unix users have their maildir in their homes (/home/%u) and the virtual mailboxes are located in /var/mail/vhosts. It works well, I only have a problem configuring dovecot. I wondered if it's possible to configure it in a way that both, unix users and virtual users, can access their mailboxes. I found some tutorials but they either give access to the "normal" unix users or to virtual users who are defined in a text file. Here some system infos: - Ubuntu 12.04.2 LTS (Kernel Version: 3.2.0-23) - Dovecot Version: 2.0.19 Hope you understand my problem. Cheers, Marco PS: It's the very first time I use a mailing list, so I hope you can forgive me possible beginner's mistakes.

[Dovecot] Passing info from mail process to mail_filter plugin script?
by Charles Cazabon 26 Sep '13

26 Sep '13

Hi, all, The mail_filter plugin allows you to pass messages through an external script/command on the way into and out of the Maildir/mbox/etc mail store. With the recent/new version of the plugin, this seems to work correctly. However, my mail-filter script (for filtering messages on the way from the mail store through the IMAP process to a remote client) needs some extra info from the IMAP mail process. I'm having difficulty figuring out how this can be accomplished. Ideally, I'd like to pass another open file descriptor (opened in the IMAP process) to the script, but I'm not sure if this is possible. Opening the file in the IMAP main.c fails, presumably due to file descriptor limits, but I don't see where restrict_fd_limit() is called there. My second choice for passing this info would be in an environment variable or argument to the mail filter script. Adding env_put() to the IMAP code doesn't seem to get the value passed to the script, presumably because the environment is getting cleared, but again I'm not certain where the list of env vars to keep is set here. There may be another way to accomplish this that I'm not thinking of? Any assistance would be appreciated.

Dears, We have a mail server (RHEL 6.0, Postfix and Dovecot 1.0.7). The output of dovecot -n is the following: # 1.0.7: /etc/dovecot.conf protocols: pop3 login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/pop3-login mail_location: mbox:~/mail:INBOX=/var/mail/%u mail_executable: /usr/libexec/dovecot/pop3 mail_plugin_dir: /usr/lib/dovecot/pop3 pop3_client_workarounds: outlook-no-nuls oe-ns-eoh auth default: passdb: driver: pam userdb: driver: passwd During the last days we face the following problem: There is great delay in the delivery of the emails. Some seem to not be delivered at all. Issuing the mailq command we get the following message for almost all the email accounts: (cannot update mailbox /var/mail/xyz for user xyz. unable to lock for exclusive access: Resource temporarily unavailable) Please send to me any suggestions, because I cannot resolve it and I receive a lot of pressure. Best Regards, Nikos

[Dovecot] 2048-bit Diffie-Hellman parameters
by Marios Titas 25 Sep '13

25 Sep '13

Currently, dovecot generates two primes for Diffie-Hellman key exchanges: a 512-bit one and a 1024-bit one. In light of recent events, I think it would be wise to add support for 2048-bit primes as well, or even better, add a configuration option that lets the user select a file (or files) containing the DH parameters In recent years, there has been increased interest in DH especially in its ephemeral version (DHE) because it provides perfect forward secrecy. In that context, the use of 1024-bit parameters might not seem such a terrible idea: if someone cracks the ephemeral key then they will only gain access to the data exchanged during that particular session. Therefore, it might not be worth the effort to crack such a key. But this is certainly not the case for IMAPS: it is quite likely that the session data will include the user's credentials.

[Dovecot] Delete to Archive?
by James E. Pace 25 Sep '13

25 Sep '13

Hi, I recently switched from being a Gmail user to running Dovecot [2.1.10] on my server. Thank you for an easy to use piece of software that solves problems! I am trying (unsuccessfully) to replicate something from GMail. When I delete a message on my iPhone (or other client), I would like to have it moved to an "All Mail" or Archive folder, instead of actually deleting it. Is this possible? Thanks, James

[Dovecot] still having dsync issues after upgrading to latest
by Matthew Kaufman 25 Sep '13

25 Sep '13

Trying to migrate a bunch of users with mbox format to maildir format. dsync creates some directories, but otherwise does nothing. (Complained about the lack of "/" as separator until I added that to config, now is silent when running dsync except with the -D flag) I have tried dumping all the dovecot that came with my OS and built the latest sources, hoping I'd at least get a little better debug information out... but no luck.

[Dovecot] imaptest-20130617 seems to be reporting spurious header changes
by Mark Weaver 25 Sep '13

25 Sep '13

I'm trying to use this to test an IMAP server I'm developing (I picked the nightly up from the link on the wiki page at http://www.imapwiki.org/ImapTest/Installation) With one client using the mailbox dovecot-crlf (http://www.dovecot.org/tmp/dovecot-crlf) I get messages like: Error: test(a)npsl.co.uk[67]: 1035253882.5041.34.camel@hurina: Header From changed 'Timo Sirainen <tss(a)iki.fi> Timo Sirainen <tss(a)iki.fi' (len 52) -> 'Timo Sirainen <tss(a)iki.fi>' (len 26): * 1 FETCH (UID 2093 FLAGS () BODY ("text" "plain" ("charset" "us-ascii") NIL NIL "7bit" 913 0) BODY[HEADER.FIELDS (From From Delivered-To) ] "From: Timo Sirainen <tss(a)iki.fi> From: Timo Sirainen <tss(a)iki.fi> Delivered-To: dovecot(a)procontrol.fi " ENVELOPE ("22 Oct 2002 05:31:22 +0300" "[dovecot] Re: Architectural questions" (("Timo Sirainen" NIL "tss" "iki.fi")) (("" NIL "dovecot-bounce" "procontrol.fi")) (("Timo Sirainen" NIL "tss" "iki.fi")) (("" NIL "dovecot" "procontrol.fi")) NIL NIL "<1035249894.5044.28.camel@hurina>" "<1035253882.5041.34.camel@hurina>") BODY[HEADER.FIELDS (Cc Cc From) ] "From: Timo Sirainen <tss(a)iki.fi> ") (I added the dump of the string length by modifying the code). As I am reading it the test program has got the wrong string rather than the server -- the From header in the mbox file is From: Timo Sirainen <tss(a)iki.fi> which is 26 characters long, not 52, and includes the closing angle bracket, and the code that prints the header out is in src/mailbox-state.c, line 377: client_state_error(client, "%s: Header %s changed '%.*s' (len %d) -> '%.*\ s' (len %d)", msg->message_id, fetch_headers[i].name, (int)orig_headers[j].value_len, (const char *)orig_headers[j].value, (int)orig_headers[j].value_len, (int)fetch_headers[i].value_len, (const char *)fetch_headers[i].value, (int)fetch_headers[i].value_len); Have I read this upside down or is there an issue with the tests? If it is an issue with the tests, any pointers as to where to start looking for the issue would be helpful. Thanks, Mark

Re: [Dovecot] Problem getting a dovecot proxy to connect to another dovecot machine via STARTTLS

I've solved the issue by setting ssl to 'any-cert' and starttls to NULL. This does a proper SSL request to the node. I still don't understand why Dovecot does a non-SSL request on an SSL port whenever I enable starttls, but I'm happy using normal SSL. Regards,

Re: [Dovecot] Bug report: "doveadm rename" encodes special characters wrongly in mUTF-7 (in fs)
by megodin＠inboxalias.com 24 Sep '13

24 Sep '13

> If doveadm says it's invalid UTF-8, it's invalid UTF-8. I guess your > terminal isn't actually using UTF-8 then, but something else. ("locale" > output should say something about UTF-8.) I guess doveadm could also > automatically translate parameters to UTF-8, but that's a bit annoying > to implement. You were absolutely right. After thorough testing I could make up the problem to the SSH-Client PuTTY I was using on a Windows machine while testing. The default "remote character setting" is "ISO-8859-1:1998 (Latin-1, West Europe)", when re-setting to "UTF-8", opening a new shell and testing the "doveadm mailbox rename ..." with german umlauts just works fine then. (Just for the sake of completeness, the "locale" settings were set to (LANG=de_DE.utf-8) globally in /etc/sysconfig/i18n per default.) > The problem here is that * is expanded by your shell, not doveadm. > And it expands into Tr&-AOQ-sh as it's in the filesystem, but that's > only the mUTF-7 encoding of it. The UTF-8 version of the name is > Tr&AOQ-sh. So doveadm only sees that you attempted to resync a > nonexistent mailbox. Using '*' with quotes would work, since doveadm > would do the expansion then. Thanks for pointing that * / '*' issue out. I now unterstand that the "doevadm mailbox rename" converts the input to UTF _before_ applying it in the filesystem. Now it makes sense that doveadm mailbox rename -u user 'Trash' 'Tr&AOQ-sh' must be expanded to Tr&-AOQ-sh. The "-" character directly after the "&"in Tr&-AOQ-sh comes from a special mUTF-Specification (as stated in RFC 3501, section 5.1.3): "In modified UTF-7, printable US-ASCII characters, except for "&", represent themselves; that is, characters with octet values 0x20-0x25 and 0x27-0x7e. The character "&" (0x26) is represented by the two-octet sequence "&-"." So e.g. if I wanted a german umlaut to be encoded in the filesystem, I must enter it directly into dovedm instead of the UTF encoded value. One small point left... > The UTF-8 version of the name is Tr&AOQ-sh Just for understanding - "Tr&AOQ-sh" is IMHO UTF-7, not UTF-8.

[Dovecot] Linux SO_REUSEPORT
by Timo Sirainen 24 Sep '13

24 Sep '13

I just read about Linux v3.9's SO_REUSEPORT feature and decided to implement it for Dovecot. Would be interesting to know how it works for people :) It's going to be in v2.2.6, which I'm planning on releasing tomorrow. Note especially the warning about the bug: http://hg.dovecot.org/dovecot-2.2/rev/a991a0547daa So the idea is that you'd do something like: service imap-login { inet_listener imap { reuse_port = yes } process_min_avail = 4 # number of CPU cores } And the load should be distributed more evenly to the processes.

[Dovecot] Fwd: lmtp
by Lampa 24 Sep '13

24 Sep '13

Hello, using dovecot with postfix with mysql. Some domains have alias. Local delivery is realized over lmtp. When lmtp delivery to aliased domains, it takes bad mail_location - it takes aliased instead real domain, so lmtp is creating domain and user directory. Lmtp doesn't make sql lookup. I need lmtp delivery to real domain and i don't want to create symlinks. mail_location = maildir:/home/mail/%d/%n/Maildir real domain: domain1.com aliased domain: domain2.com rcpt: user(a)domain2.com lmtp deliver message to /home/mail/domain2.com/user/Maildir instead /home/mail/domain1.com/user/Maildir -- Lampa

[Dovecot] Permission error
by Koenraad Lelong 24 Sep '13

24 Sep '13

Hi, I'm migrating an existing dovecot (1. series) to new hardware. The new dovecot is a 2. series. I copied the old config and did a doveconf -n -c /etc/dovecot/dovecot.conf > dovecot-2.conf Then I moved the dovecot-2.conf to dovecot.conf and restarted dovecot. When Postfix tries to deliver a message I get this error : 2013-09-16 11:00:10 auth: Fatal: net_connect_unix(auth-worker) in directory /run/dovecot failed: Permission denied (euid=65534(nobody) egid=65534(nogroup) missing +r perm: /run/dovecot/auth-worker, dir owned by 0:0 mode=0755) 2013-09-16 11:00:10 master: Error: service(auth): command startup failed, throttling I tried different things with /run/dovecot/auth-worker, but the error remains.

[Dovecot] doveadm mailbox create error codes
by Micah Anderson 24 Sep '13

24 Sep '13

Hello, I'm trying to find out what the different 'doveadm mailbox create' error codes are. I've been looking through the source, but I can't seem to find them. I did determine that '65' happens when "Error: Can't create mailbox x: Mailbox already exists", but I've also received error 67, and the more mysterious error code 16640. Thanks for any pointers! micah

Re: [Dovecot] Bug report: "doveadm rename" encodes special characters wrongly in mUTF-7 (in fs)
by megodin＠inboxalias.com 24 Sep '13

24 Sep '13

Hi there Timo, first of all thank you for taking your time for support! > Forget about mUTF-7 with Dovecot. It's an IMAP-protocol relic, and > Dovecot is trying to get rid of it in as many places as possible. > Although by default the filesystem users mUTF-7, but that can also > be changed with a setting. Thanks for clarifying this. > I suspect your shell is breaking the 8bit chars into invalid UTF-8. I > just tried and it works fine with me. Sorry, we got confusion here... apparently my (lousy) freemail provider which I use to post on this mailinglist doesn't send some special characters etc. unaltered exactly as I typed - so I made a console screenshot of the doveadm rename problem to make things clear. Please have a look here, it will reveal the doveadm rename problem (and that my shell is working fine): http://i.imgur.com/08wKji4.png > > To get things worse, when renaming the mailfolder in Thunderbird to > > "geschÃÂ¤ftliches" it gets correctly written in the filesystem as > > "gesch&AOQ-ftliches"- but afterwards it's NOT found anymore in the > > dovecot index, e.g. when trying doveadm force-resync -u user it is > > not listed anymore (untilback-renaming in fs to the name it was > > indexed before). > Folders aren't indexed by default (mailbox_list_index=no) and > force-resync doesn't affect them. Are you saying > "doveadm mailbox list -u user" doesn't show some folder? I'm not > aware of any bugs related to this. No, the "doveadm mailbox list -u user" works just fine. BUT - I'm still wondering about the resync issue - As I understand the "doveadm force-resync -u user *" command rebuilds the index for the MAILS within the mailfolders? If so, how can the resync be done if the mailfolder itself is not found by doveadm anymore? > I'd need to get some more specifics.

For clearing up my point, I made another console screenshot with red markings to point out the problem (bug).

[Dovecot] Vacation message and DMARC validation
by Gerson Moraes 23 Sep '13

23 Sep '13

Greetings, I have found an issue in the interaction between sieve vacation messages and the SPF, DKIM and DMARC email validation systems. For example, let's say we have a message coming from a(a)a.com to b(a)b.com at a server imap.mydomain.com. The account b(a)b.com has a vacation rule in sieve, and that generates an autoresponse to a(a)a.com. Our problem begins with the definition of section-5.1 in RFC5230 <https://tools.ietf.org/html/rfc5230#section-5.1>. It says that the envelope-from in vacation messages should be set to <>. This is the behavior currently implemented in Dovecot. We have recently added DMARC's authentication to our e-mail servers. DMARC needs one of the two authentication to pass, either SPF or DKIM. SPF works, but not the way DMARC needs it to. DMARC needs a valid SPF record that also matches the "From:" header. In this message, there are no envelope-from, so there are no domain to validate. This is the reason we use SRS to rewrite envelope-from (to do that we use the server address). The last option is to use DKIM authentication. We have clustered SMTP servers. So, in order to make a DKIM signature, the vacation message needs to be sent to the right server. That is, the server where the key to account b(a)b.com is available. To do that, we are implementing a modification to Dovecot source allowing the use of the envelope-from. The modified envelope-from will be used with the Postfix option "sender_dependent_relayhost_maps" in order to choose the right cluster. This does not break RFC5230, because the use of null sender is only a recommendation. I would like to know if a patch to the main project would be appreciated. Could you also please confirm if there are any future plans involving this feature, like an optional configuration for custom envelope-from? Thanks in advance, Gerson Moraes Digirati

[Dovecot] default client_limit
by Micah Anderson 23 Sep '13

23 Sep '13

I recently upgraded my dovecot from 2.1 to 2.2, and when I started, I received this message: doveconf: Warning: service auth { client_limit=1000 } is lower than required under max. load (1024) Searching through my configs, I do not have 1024 set anywhere. In order to stop this I set client_limit=1024 in my auth{} block... this seemed odd that the defaults disagreed with each other. However, it made me realize that my system could probably handle more, if it were properly tuned, and the different limit settings at their defaults are probably smaller than they could be for my server and the load it is under. So, I'm wondering how I can accurately set some of these values? The different possible things that can be set are: default_process_limit (for some reason I have this set to 256) default_client_limit (default) default_vsz_limit (I have this set to 512M) for the imap-login service, I have: service_count = 0 process_min_avail = 10 vsz_limit = 512M for service pop3-login, these are set: service_count = 0 process_min_avail = 10 vsz_limit = 512M for service imap, process_limit = 2048 service auth, I've just set the client_limit=1024 I've also got a ulimit -n set to 2048 and in my sysctl.conf, I have the following: fs.inotify.max_user_instances = 2048 because I was seeing this in the logs: Warning: Inotify instance limit for user 8 (UID mail) exceeded, disabling. Increase /proc/sys/fs/inotify/max_user_instances What I am looking for is a few things: . is there a formula for setting a proper value for some of these? . will dovecot warn me when I've reached a limit, so I can adjust these? thanks for any suggestions or improvements, I'm pretty sure this system can handle a lot more than it is doing right now, I just am unclear on how to tune it up to do that. micah

[Dovecot] Expunged message reappeared, giving a new UID
by Simon Fraser 23 Sep '13

23 Sep '13

I am running dovecot 2.2.2 with tcp based replication, and experiencing some duplicated emails. `doveconf -n` output is below. I have narrowed it down to the following scenario: An email arrives, and is successfully replicated to both nodes. It is in INBOX/new/ at this point on both servers. Connect with a mail client, and delete the message - without delayed expunge. So, for example, mutt (press 'd' then '$' to sync the mailbox), or Evolution set to immediately delete. The following log entry appears on the server the client is connected to: Jul 26 10:40:55 intmail3a dovecot: imap(srf): Warning: /mail/spool/s/srf/mail/INBOX/dovecot-uidlist: Duplicate file entry at line 5: 1374831638.M830754P11591.intmail3a,S=1289,W=1321 (uid 733481 -> 733482) - retrying by re-reading from beginning Jul 26 10:40:55 intmail3a dovecot: imap(srf): Warning: Maildir /mail/spool/s/srf/mail/INBOX: Expunged message reappeared, giving a new UID (old uid=733481, file=1374831638.M830754P11591.intmail3a,S=1289,W=1321) The email reappears in the mailbox, although this time it is in INBOX/new on one node and INBOX/cur on the other. As best I can tell it's always in 'new' on the server the client was connected to and in 'cur' on the other. If any other mailbox operation occurs before the delete (Marking the message in question as 'read', receiving a new message into the mailbox in a different lmtp session, marking as read or deleting & expunging some other message) then this prevents the duplication from happening. What can I do to prevent this happening? Is there a synchronisation interval I can adjust, perhaps? Although the message does get synchronised initially.

[Dovecot] mdbox index directories: bug?
by Holecz Endre 22 Sep '13

22 Sep '13

Hi, I'm using mdbox now (Dovecot 2.2.4), with indexes on a separate disk. Works fine, but the directories for indexes are also present in the storage folder, and are empty. Userdb (sql) returns this: home /var/vmail/domains/somedomain/someuser mail mdbox:~/mdbox:INDEX=/mnt/spool/dovecot/index/somedomain/s/someuser And the created directory structure is: /var/vmail/domains/somedomain/someuser /mdbox /mailboxes /INBOX /dbox-Mails /storage /mnt/spool/dovecot/index/somedomain/s/someuser /mailboxes /INBOX /storage /var/vmail/domains/somedomain/someuser/mdbox/mailboxes/* is always empty. Am I doing something wrong, or is this by design? :) Regards, Endre

[Dovecot] doveadm sync only creates directories, don't sync messages?
by Matthew Kaufman 22 Sep '13

22 Sep '13

Running Dovecot 2.1.7. I'm trying to migrate from an environment with mbox files to a maildir configuration. I remove all vestiges of my maildir over in /var/mail I put my old mailboxes in ./Mail and my old inbox in ./matthew. I issue this command: doveadm sync -u matthew(a)matthew.at mbox:./Mail:INBOX=./matthew Initially it gave me errors about separator, so I set the separator in the inbox namespace to "/" explicitly. Now that I've done that, and re-run it, over in the right place /var/mail, it creates "matthew" and a subdirectory "Mail". That's it. Doesn't take long to do it, either. But it doesn't copy any messages at all. I must be doing something wrong... but what? Matthew Kaufman matthew(a)eeph.com

[Dovecot] pop3c migration?
by Gedalya 22 Sep '13

22 Sep '13

Hi, I'm running dsync migrations using imapc and the source IMAP server is just too slow. It has taken 8 hours to migrate a mailbox with 47,000 messages. It seems most of the mailboxes are never accessed with IMAP, so it would be just as good to migrate them via POP3 which should work faster in my case. Is this actually meant to work? doveadm -D -o pop3c_user=xxxxxx(a)example.com -o 'pop3c_password=*******' -o pop3c_host=120.121.122.123 backup -u yyyyy(a)example.com -R pop3c: gives: doveadm(root): Debug: Loading modules from directory: /usr/lib/dovecot/modules doveadm(root): Debug: Module loaded: /usr/lib/dovecot/modules/lib20_listescape_plugin.so doveadm(root): Debug: Loading modules from directory: /usr/lib/dovecot/modules/doveadm doveadm(root): Debug: Skipping module doveadm_acl_plugin, because dlopen() failed: /usr/lib/dovecot/modules/doveadm/lib10_doveadm_acl_plugin.so: undefined symbol: acl_user_module (this is usually intentional, so just ignore this message) doveadm(root): Debug: Skipping module doveadm_expire_plugin, because dlopen() failed: /usr/lib/dovecot/modules/doveadm/lib10_doveadm_expire_plugin.so: undefined symbol: expire_set_init (this is usually intentional, so just ignore this message) doveadm(root): Debug: Skipping module doveadm_quota_plugin, because dlopen() failed: /usr/lib/dovecot/modules/doveadm/lib10_doveadm_quota_plugin.so: undefined symbol: quota_user_module (this is usually intentional, so just ignore this message) doveadm(root): Debug: Skipping module doveadm_zlib_plugin, because dlopen() failed: /usr/lib/dovecot/modules/doveadm/lib10_doveadm_zlib_plugin.so: undefined symbol: i_stream_create_deflate (this is usually intentional, so just ignore this message) doveadm(root): Debug: Skipping module doveadm_fts_plugin, because dlopen() failed: /usr/lib/dovecot/modules/doveadm/lib20_doveadm_fts_plugin.so: undefined symbol: fts_list_backend (this is usually intentional, so just ignore this message) doveadm(yyyyy(a)example.com): Debug: Added userdb setting: mail=maildir:/stor/real/domains/example.com/yy/yyyyy/Maildir doveadm(yyyyy(a)example.com): Debug: Added userdb setting: plugin/quota_rule=*:storage=5120M doveadm(yyyyy(a)example.com): Debug: Effective uid=1001, gid=1001, home=/stor/real/domains/example.com/yy/yyyyy doveadm(yyyyy(a)example.com): Debug: Namespace : type=private, prefix=POP3-MIGRATION-NS/, sep=, inbox=no, hidden=yes, list=no, subscriptions=yes location=pop3c: doveadm(yyyyy(a)example.com): Debug: fs: root=, index=, control=, inbox=, alt= doveadm(yyyyy(a)example.com): Debug: Namespace inbox: type=private, prefix=, sep=/, inbox=yes, hidden=no, list=yes, subscriptions=yes location=maildir:/stor/real/domains/example.com/yy/yyyyy/Maildir doveadm(yyyyy(a)example.com): Debug: maildir++: root=/stor/real/domains/example.com/yy/yyyyy/Maildir, index=, control=, inbox=/stor/real/domains/example.com/yy/yyyyy/Maildir, alt= dsync(yyyyy(a)example.com): Debug: Effective uid=1001, gid=1001, home=/stor/real/domains/example.com/yy/yyyyy dsync(yyyyy(a)example.com): Debug: Namespace : type=private, prefix=POP3-MIGRATION-NS/, sep=, inbox=no, hidden=yes, list=no, subscriptions=yes location=pop3c: dsync(yyyyy(a)example.com): Debug: fs: root=, index=, control=, inbox=, alt= dsync(yyyyy(a)example.com): Debug: Namespace inbox: type=private, prefix=, sep=/, inbox=yes, hidden=no, list=yes, subscriptions=yes location=pop3c: dsync(yyyyy(a)example.com): Debug: fs: root=, index=, control=, inbox=, alt= Segmentation fault remembering something about that... : #

Hi! Is there any possibility to let dovecot serve >1024 Bit DH Parameters at SSL/TLS-connections? Is it possible to replace /var/lib/dovecot/ssl-parameters.ssl with DH-parameter generated by openssl? If not: Are there any plans to implement that? Thank you!

We did this test: ./imaptest host=example.com port=143 user=strack pass=secret disconnect_quit no_pipelining mbox=dovecot-crlf That's what we get in dovecot's log: Sep 10 11:17:04 imap-login: Info: Login: user=<strack>, method=PLAIN, rip=10.10.10.31, lip=10.10.10.21, mpid=22810, session=<EurP9wPmVgCBu/Qf> Sep 10 11:17:04 imap-login: Info: Login: user=<strack>, method=PLAIN, rip=10.10.10.31, lip=10.10.10.21, mpid=22811, session=<mSXT9wPmWgCBu/Qf> Sep 10 11:17:04 imap-login: Info: Login: user=<strack>, method=PLAIN, rip=10.10.10.31, lip=10.10.10.21, mpid=22812, session=<1GbR9wPmWACBu/Qf> Sep 10 11:17:04 imap-login: Info: Login: user=<strack>, method=PLAIN, rip=10.10.10.31, lip=10.10.10.21, mpid=22813, session=<JKbQ9wPmVwCBu/Qf> Sep 10 11:17:04 imap-login: Info: Login: user=<strack>, method=PLAIN, rip=10.10.10.31, lip=10.10.10.21, mpid=22814, session=<USLS9wPmWQCBu/Qf> Sep 10 11:17:04 imap(strack): Panic: file mbox-storage.c: line 712 (mbox_transaction_unlock): assertion failed: (mbox->box.transaction_count > 0 || mbox->mbox_lock_type == F_UNLCK) Sep 10 11:17:04 imap(strack): Error: Raw backtrace: /usr/lib64/dovecot/libdovecot.so.0() [0x3c7824660a] -> /usr/lib64/dovecot/libdovecot.so.0() [0x3c78246656] -> /usr/lib64/dovecot/libdovecot.so.0() [0x3c78219eaa] -> /usr/lib64/dovecot/libdovecot-storage.so.0() [0x3c786600c0] -> /usr/lib/dovecot/lib10_quota_plugin.so(+0xb7e7) [0x7f113b5427e7] -> /usr/lib/dovecot/lib10_quota_plugin.so(+0xb218) [0x7f113b542218] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mbox_sync+0x88) [0x3c7865fea8] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mbox_transaction_save_commit_post+0x27) [0x3c78657c07] -> /usr/lib64/dovecot/libdovecot-storage.so.0() [0x3c786a5313] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mail_index_transaction_commit_full+0x9f) [0x3c786b3cdf] -> /usr/lib64/dovecot/libdovecot-storage.so.0(index_transaction_commit+0x8a) [0x3c786a4f5a] -> /usr/lib64/dovecot/libdovecot-storage.so.0() [0x3c78660121] -> /usr/lib/dovecot/lib10_quota_plugin.so(+0xb8af) [0x7f113b5428af] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mailbox_transaction_commit_get_changes+0x3e) [0x3c7867aa9e] -> dovecot/imap() [0x408b3a] -> dovecot/imap() [0x4088e4] -> dovecot/imap() [0x408d3c] -> dovecot/imap(cmd_append+0x139) [0x408f99] -> dovecot/imap(command_exec+0x3d) [0x41155d] -> dovecot/imap() [0x41046e] -> dovecot/imap() [0x41055a] -> dovecot/imap(client_handle_input+0x135) [0x410785] -> dovecot/imap(client_input+0x5f) [0x4110af] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_call_io+0x36) [0x3c78252c16] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handler_run+0x9f) [0x3c78253c9f] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_run+0x28) [0x3c78252bb8] -> /usr/lib64/dovecot/libdovecot.so.0(master_service_run+0x13) [0x3c7823e083] -> dovecot/imap(main+0x29d) [0x4195bd] Sep 10 11:17:04 imap-login: Info: Login: user=<strack>, method=PLAIN, rip=10.10.10.31, lip=10.10.10.21, mpid=22826, session=<KyHU9wPmWwCBu/Qf> Sep 10 11:17:04 imap-login: Info: Login: user=<strack>, method=PLAIN, rip=10.10.10.31, lip=10.10.10.21, mpid=22827, session=<kxTY9wPmXACBu/Qf> Sep 10 11:17:04 imap-login: Info: Login: user=<strack>, method=PLAIN, rip=10.10.10.31, lip=10.10.10.21, mpid=22828, session=<CXXg9wPmXQCBu/Qf> Sep 10 11:17:05 imap(strack): Fatal: master: service(imap): child 22806 killed with signal 6 (core dumped) Sep 10 11:17:05 imap(strack): Info: Connection closed in=49 out=3832 Sep 10 11:17:05 imap(strack): Info: Connection closed in=49 out=3832 That's the backtrace of the coredump: Loaded symbols for /lib64/libnss_files.so.2 Reading symbols from /lib64/libnss_sss.so.2...Reading symbols from /usr/lib/debug/lib64/libnss_sss.so.2.debug...done. done.

From the stacktrace I could see that the problem origins from the quota plugin. Thus, when I disabled the quota plugin the problem went away. The problem did only occur on a high concurrency level on one mbox/folder, running imaptest with only one user and 10 clients. When we run imaptest in a more real-world fashion with several thousand of users and clients=100, the error did not occur. Because of this I am not sure how problematic this bug will be in a production environment? What do you think? Any help is greatly appreciated! br Harald Strack -- Harald Strack, Dipl.Inf.(FH) IT Development ssystems c/o berliner gazette Danziger Str. 31 10435 Berlin Tel: +49 30 2023 6071 - 1 http://www.ssystems.de

[Dovecot] Read-only account through INDEX=MEMORY:CONTROL=MEMORY and non-writable Unix-permissions

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, my goal is to provide a special mailbox for some mail accounts. The user should get the information, to look somewhere else.

[Dovecot] permission problem when using public namespace and "subscription = yes"
by Lars Uhlmann 22 Sep '13

22 Sep '13

I have configured an public namespace "Test" for a group of users: | namespace public { | separator = . | prefix = Test. | location = maildir:/mailroot/public/Test | hidden = no | list = yes | subscriptions = yes | } Using each users own subscription file for a public mailbox doesn't make sense when the mailbox is heavily used. Every directory operation (create/rename) needs to be synced between all subscribers automatically and immediately. So I set "subscriptions = yes". My ACLS look like this: | user=mark lrwstiekx | user=tim lrwstiekx | user=max lr | user=jenny lrwstiekx | user=louis lr Nevertheless _all_ my mail users still have access to the namespace's directory tree. It is my understanding that when a user doesn't has 'lookup' access, he should not be able to subscribe to this mailbox. In my opinion this is a security problem. ACLs must be processed _before_ a shared subscrition file is parsed. regards Lars

I use bl.blocklist.de as a DNSRBL for ssh BFD, but I think it also detects BFD for other protocols: http://www.blocklist.de/en/index.html The nice thing about this RBL is that you can also contribute by configuring your Fail2Ban/DenyHost to forward logs to the maintainers, to widen the detection network. I get about a 60% hit on ssh BFD attacks. I also found http://openbl.org but they distribute it as a downloadable file rather than as a DNSRBL. Maybe I can introduce the latter to the former.

[Dovecot] Solved: startup failures "net_listen_unix(...) failed: Invalid argument"
by C. Mills 22 Sep '13

22 Sep '13

I ran into this and had a bit of trouble tracking a diagnosis down, so here it is for the archives in case anyone else runs into this. A new installation of dovecot was failing to start, with these messages: $ ./sbin/dovecot Error: service(imap-urlauth): net_listen_unix(.../var/run/dovecot/token-login/imap-urlauth) failed: Invalid argument Error: service(auth): net_listen_unix(.../var/run/dovecot/token-login/tokenlogin) failed: Invalid argument Fatal: Failed to start listeners Some of the other processes seemed to be starting up fine, and they created sockets in the expected dir, but the above two wouldn't. stracing the processes didn't show a lot, but eventually I checked the length of the installation path, and found the above two socket paths were exceeding the maximum path length limit for Unix sockets -- 108 chars on my Linux boxen. I haven't checked SuS or Posix to see what the standards say the actual minimum required size for the maximum path length is -- it might be shorter yet on other systems. Moving the installation to a less deeply nested hierarchy fixed the problem. I hope this saves someone else a headache someday. C.

[Dovecot] dovecot and PFS
by Emmanuel Dreyfus 22 Sep '13

22 Sep '13

Hi Is there known advices on how to favor PFS with dovecot? In Apache, I use the following directives, with cause all modern browsers to adopt 256 bit PFS ciphers, while keeping backward compatibility with older browsers and avoiding BEAST attack: SSLProtocol all -SSLv2 SSLHonorCipherOrder On SSLCipherSuite ECDHE@STRENGTH:ECDH@STRENGTH:DH@STRENGTH:HIGH:-SSLv3-SHA1:-TLSv10 -SHA1:RC4:!MD5:!DES:!aNULL:!eNULL dovecot does not care about BEAST, since attacker cannot inject trafic. Therefore the cipher list get simplier in dovecot.conf: ssl_cipher_list = ECDHE@STRENGTH:ECDH@STRENGTH:DH@STRENGTH:HIGH:!MD5:!DES:!aNULL :!eNULL But that list is good for browsers. I am not aware of documentation about what ciphers are advertised by various mail client. How can I know if that setting has some success pushing PFS? How can I discover which clients fail to negociate PFS ciphers? -- Emmanuel Dreyfus manu(a)netbsd.org

[Dovecot] mailbox_list_index, stops showing new mails in mailboxes
by Anton Lundin 22 Sep '13

22 Sep '13

Hello. I'm having some weird problem with (probably) mailbox_list_index, that it doesn't see new mail in mailboxes. I'm using 2.2.4 over imap and ssh/imap, and after a while dovecot stops noticing new mail in some folders. Its always the same 2-3 folders of about 30. I read something about list-index corruption in 2.2.2, and i thought it was that i was running into earlier, but this problem still occurs. This is dovecot 2.2.4, running on Solaris 10 x86_64 to homedirs on zfs, where procmail is used to deliver mail to mailboxes in mbox-format. I've tried to purge all indexes and let dovecot rebuild them, but the problem reoccurs after a couple of days. How can i help to debug this issue? Should i grab dovecot.list.index when its out-of-sync for debugging? //Anton -- Anton Lundin +46702-161604

[Dovecot] verbose_proctitle cuts dsync to proctitle to "dsyn"

Hi Timo, little cosmetic bug report: using "verbose_proctitle = yes" shortens the proctitle of dsync to just "dsyn".

[Dovecot] Problem with MySQL virtual users and dsync
by Jordan Cook 22 Sep '13

22 Sep '13

Hello, I am using dovecot 2.2.5 on FreeBSD and I am having trouble using dsync with SSH. Everything on the server seems to be working fine (I can login, receive and send emails etc). I am using SQL for both passdb, and userdb and this seems to work fine. The 'doveadm user' command returns all the correct information for the user. I am getting the following errors in my log file: Aug 27 21:34:17 server dovecot: replicator: Error: userdb lookup: Connecting timed out Aug 27 21:34:17 server dovecot: replicator: Error: userdb lookup: Disconnected unexpectedly Aug 27 21:34:20 server last message repeated 173381 times It did seem to do an initial sync, but after that nothing is being synchronised.

[Dovecot] Logging pre-rewrite user ID for application-specific passwords
by Steven Murdoch 22 Sep '13

22 Sep '13

I have set up Dovecot v2.2.5 with application-specific passwords, along the lines of this blog post (http://www.dgsiegel.net/news/2013_05_21-application_specific_passwords_for_…) My users file looks like: user-foo:{BLF-CRYPT}$2...:42:42::/home/user::allow_nets=127.0.0.1/32 user=user user-bar:{BLF-CRYPT}$2...:42:42::/home/user::user=user user:{BLF-CRYPT}$2...:42:42::/home/user::nologin In this way, user-foo can log in with one password (but only from localhost), user-bar can log in from any host with a different password, but both actually being treated as the same user. When these users log in through, the log entries look like: Aug 26 23:03:01 hostname dovecot: imap-login: Login: user=<user>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=12345, TLS Whereas I would like to see the original user name (prior to the re-write), i.e. user-foo and user-bar so I can keep track of which user names are in use and from where. Is there some way to do this? I couldn't see any of the variables being suitable. There is some information in the debug logs, but I would prefer not to need to leave this on when I don't need them. Thanks in advance. Steven

[Dovecot] Dovecot never release preallocated space in mdbox
by Stéphane BERTHELOT 22 Sep '13

22 Sep '13

Hello everyone, I am currently evaluating dovecot for our new email production servers (20k+ mailboxes) and found out something strange. I'm using those settings on Dovecot 2.2.4 (x86_64 / Slackware / compiled from sources) mdbox_rotate_size = 128M mdbox_rotate_interval = 1d mdbox_preallocate_space = yes with virtual users and location like : mail_location = mdbox:~/mdbox I don't think the remaining config is relevant but ask me if you need some other parts. Using test accounts for 2 weeks now I've figured that the 128M preallocated space is never 'hole punched" (to use a similar term than "man fallocate" on Linux), even when rotating m.* files. From what I understand those files will never be appended again because of the mdbox_rotate_interval. Then doveadm purge creates new files so old ones would never grow again. Here is an example of a mdbox storage using ls -ls (which shows allocated VS used space) total 4065176 1884 -rw------- 1 mail mail 1926656 Jul 29 10:55 dovecot.map.index 4 -rw------- 1 mail mail 460 Jul 29 11:26 dovecot.map.index.log 48 -rw------- 1 mail mail 44304 Jul 29 10:55 dovecot.map.index.log.2 131072 -rw------- 1 mail mail 133165066 Jul 19 15:31 m.10 131072 -rw------- 1 mail mail 133507393 Jul 19 15:32 m.13 131072 -rw------- 1 mail mail 134155182 Jul 19 15:33 m.14 131072 -rw------- 1 mail mail 134213403 Jul 19 15:30 m.2 131072 -rw------- 1 mail mail 46464 Jul 21 04:30 m.21 131072 -rw------- 1 mail mail 134215030 Jul 19 15:30 m.3 131072 -rw------- 1 mail mail 25852 Jul 25 01:54 m.32 131072 -rw------- 1 mail mail 2360 Jul 26 00:05 m.34 131072 -rw------- 1 mail mail 169073 Jul 27 23:18 m.35 131072 -rw------- 1 mail mail 31624 Jul 27 01:55 m.36 131072 -rw------- 1 mail mail 134216982 Jul 28 04:30 m.37 131076 -rw------- 1 mail mail 134217804 Jul 28 04:30 m.38 131072 -rw------- 1 mail mail 134217341 Jul 28 04:30 m.39 131072 -rw------- 1 mail mail 134213719 Jul 19 15:30 m.4 131072 -rw------- 1 mail mail 29740970 Jul 28 04:30 m.40 131072 -rw------- 1 mail mail 129175917 Jul 28 04:30 m.41 131072 -rw------- 1 mail mail 133174937 Jul 28 04:30 m.42 131072 -rw------- 1 mail mail 633436 Jul 28 04:30 m.43 131072 -rw------- 1 mail mail 3154623 Jul 28 04:30 m.44 131072 -rw------- 1 mail mail 3676879 Jul 28 04:30 m.45 131072 -rw------- 1 mail mail 468158 Jul 28 04:30 m.46 131072 -rw------- 1 mail mail 26964 Jul 28 04:30 m.47 131072 -rw------- 1 mail mail 3574599 Jul 28 04:30 m.48 131072 -rw------- 1 mail mail 3789133 Jul 28 04:30 m.49 131072 -rw------- 1 mail mail 134215016 Jul 19 15:30 m.5 131072 -rw------- 1 mail mail 1280074 Jul 28 04:30 m.50 131076 -rw------- 1 mail mail 635459 Jul 28 22:47 m.51 131072 -rw------- 1 mail mail 1459418 Jul 29 10:55 m.52 131072 -rw------- 1 mail mail 132941013 Jul 29 11:26 m.53 131072 -rw------- 1 mail mail 134213475 Jul 19 15:30 m.7 131072 -rw------- 1 mail mail 132240074 Jul 19 15:31 m.9 There's a lot of "lost" space since preallocated space would only be reclaimed when *all* emails in m.X file have refcount=0 and after a doveadm purge call, if I read well the dovecot docs. On mailboxes patterns with low incoming mail (< 100kb / day) this would waste much space. Of course I can decrease rotate size a lot but it would then produce a lot of files and would certainly become similar performance-wise to sdbox/maildir/... There would certainly be smart to use something similar to "FALLOC_FL_PUNCH_HOLE" on rotation (when doing close() ?) so that when we're sure there won't be anymore data appended to file that the allocated space == used space. I will disable space preallocation for our next tests since it wastes much storage for us ; did you have any feedback on how much it may affect performance ? I found in this ML archives some messages about the implementation but didn't see anyone clearly stating how much better preallocation is. Thanks, best regards, Stephane Berthelot.

[Dovecot] Deleted mails in dsync backups
by Wolfgang.Friebel＠desy.de 22 Sep '13

22 Sep '13

Hello we are doing regular backups of the mdbox mail folders using dsync -u username backup mdbox:/somedir/BACKUPS/username (still with version 2.1.10, but 2.2.5 is in testing phase) We do observe that the directory size in the BACKUPS directory is growing with respect to the original mail folders. I believe this is due to deleted mails not being purged in the backup. We are doing regular doveadm purge -A cleanups, but this does (of course) not affect the backups and subsequent dsync backup runs seem not to clean up deleted mails in the backup either. Will the behaviour of the dsync backup command deal with deleted mails in the 2.2.5 release? If not, what could we do to get rid of the deleted mails in the backup (or is there another reason for the growth in size) We have e.g. after 9 month of running with 2.1.10 du -sk username 588520 du -sk /somedir/BACKUPS/username 863024 -- Wolfgang Friebel Deutsches Elektronen-Synchrotron DESY

[Dovecot] Rfc: Limit the size of an email IN the mailbox
by Ralf Hildebrandt 22 Sep '13

22 Sep '13

Currently we're in the process of migrating Dovecot mailboxes to Exchange. This is all working very well, except for the occasional user, who used his/her Drafts folder as a file storage: They started writing an email containing lots of image attachments (and thus exceeding our maximum_message_size by far). So the mail never gets sent, but stays in the Drafts folder. Once I try moving that mail to exchange, it won't accept the message since it's too big. I think it would be interesting to have a limit on the total size of an IMAP object, just like in SMTP.
