[Dovecot] SSL with startssl.com certificates
by Dan Langille 11 Oct '13

11 Oct '13

I'm using Dovecot 2.2.5. I'm setting up and new IMAPS server for personal use (i.e. only me). I have success with self-signed certificates but not with others (e.g. StartSSL.com) With StartSSL certs: I've been able to connect and test commands via: openssl s_client -connect imaps.unixathome.org:993 Can you configure your iPhone or Macbook to access the above? Authentication isn't the issue. Connection is the issue. I've been able to get Thunderbird to connect and access my mail. However, I've been unable to get my iPhone or my Mac configured to use the same IMAP server. On the iPhone, adding the new Mail account causes the Settings app to crash on a persistently consistent basis when adding the new account. The crash occurs when connecting to the IMAPS server. Configuration never completes. I suspect the problem is SSL because in both cases (iPhone and Mac), I see these messages I see in the logs: *** /var/log/debug.log *** Sep 13 11:50:32 imaps dovecot: imap-login: Debug: SSL: where=0x2002, ret=-1: SSLv3 read client certificate A [166.137.84.11] Sep 13 11:50:45 imaps dovecot: auth: Debug: auth client connected (pid=31647) Sep 13 11:50:45 imaps dovecot: imap-login: Debug: SSL: where=0x10, ret=1: before/accept initialization [166.137.84.11] Sep 13 11:50:45 imaps dovecot: imap-login: Debug: SSL: where=0x2001, ret=1: before/accept initialization [166.137.84.11] Sep 13 11:50:45 imaps dovecot: imap-login: Debug: SSL: where=0x2002, ret=-1: SSLv2/v3 read client hello A [166.137.84.11] Sep 13 11:50:45 imaps dovecot: imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 read client hello A [166.137.84.11] Sep 13 11:50:45 imaps dovecot: imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 write server hello A [166.137.84.11] Sep 13 11:50:45 imaps dovecot: imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 write certificate A [166.137.84.11] Sep 13 11:50:45 imaps dovecot: imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 write server done A [166.137.84.11] Sep 13 11:50:45 imaps dovecot: imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 flush data [166.137.84.11] Sep 13 11:50:45 imaps dovecot: imap-login: Debug: SSL: where=0x2002, ret=-1: SSLv3 read client certificate A [166.137.84.11] *** /var/log/maillog *** Sep 13 11:50:46 imaps dovecot: imap-login: Warning: SSL failed: where=0x2002: SSLv3 read client certificate A [166.137.84.11] Sep 13 11:50:46 imaps dovecot: imap-login: Disconnected (no auth attempts in 1 secs): user=<>, rip=166.137.84.11, lip=199.233.228.197, TLS handshaking: Disconnected, session=<a7AJd0LmWwCmiVQL> /usr/local/etc/ssl/imaps.unixathome.org.crt contains only the cert issued by StartSSL /usr/local/etc/ssl/imaps.unixathome.org.nopassword.key contains a no-password key generated by myself.

[Dovecot] cached message size errors
by Charles Sprickman 11 Oct '13

11 Oct '13

Hello, We recently moved from courier to dovecot, and I'm seeing a handful of errors that prevent people from retrieving email. Below is a snippet of the log sequence I see when this happens: Oct 10 13:44:24 mbox dovecot: imap(xxx(a)bway.net): Error: Cached message size smaller than expected (1759 < 1830) Oct 10 13:44:24 mbox dovecot: imap(xxx(a)bway.net): Error: Maildir filename has wrong S value, renamed the file from /home/vpopmail/domains/bway.net/1/xxx/Maildir/cur/1381381552.91972.xena.bway.net,S=1759:2,b to /home/vpopmail/domains/bway.net/1/xxx/Maildir/cur/1381381552.91972.xena.bway.net,S=1830:2,b Oct 10 13:44:24 mbox dovecot: imap(xxx(a)bway.net): Error: Corrupted index cache file /home/vpopmail/domains/bway.net/1/xxx/Maildir/dovecot.index.cache: Broken physical size for mail UID 447401 Oct 10 13:44:24 mbox dovecot: imap(xxx(a)bway.net): Error: read(/home/vpopmail/domains/bway.net/1/xxx/Maildir/cur/1381381552.91972.xen… failed: Invalid argument Oct 10 13:44:24 mbox dovecot: imap(xxx(a)bway.net): Disconnected: Internal error occurred. Refer to server log for more information. [2013-10-10 13:44:24] in=784 out=3017 Basically it looks like dovecot detects a mismatch in the file size vs. the file size embedded in the maildir filename, tries to fix it and then has issues reading the fixed file. Removing the file in question allows the user to retrieve email. The "invalid argument" error seems especially strange, as I'm able to view the file by hand with no problems. Blowing away the indexes and letting them get recreated seems to not help at all. This was an old vpopmail setup with both maildrop and vdelivermail doing the final delivery both now and prior to the migration to dovecot. For a quick fix, is there a way to have dovecot ignore the error and present the rest of the mailbox? Longer term fix, I'm not even sure where to start I've used dovecot elsewhere for quite some time (with maildirs) and I've never had an issue like this. 'doveconf -n' below...

[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.

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>

[Dovecot] Proxy to gmail not working
by Alex Wanderley 07 Oct '13

07 Oct '13

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. Thanks a lot, Alex # 2.2.5: /etc/dovecot/dovecot.conf # OS: Linux 2.6.18-308.8.2.el5xen x86_64 CentOS release 5.8 (Final) auth_cache_negative_ttl = 10 mins auth_cache_size = 1 k auth_cache_ttl = 10

[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.

[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?

[Dovecot] Problems getting Squirrelmail and Avelsieve to connect to Pigeonhole
by Steve 06 Oct '13

06 Oct '13

[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.

I really understand only now, that the basis is really e-mail, not the browsers, or other things, for the life on the internet... That the basis is really e-mail these days on Russia Today said also Ladar Levison, the Lavabit.com founder that fought for his users' privacy all the way to losing his business. I admire people of such integrity and humanity! Not like the Canadian Hushmail which sold NSA's whistleblower Thomas Drake... Who says I don't like people from NSA. I highly regard him, and Ross Tice, and some others! It's the usual perception most of people have, that email is less important/less advanced, whatnot, not just me, but not delving into it here. I'm yet to see if my "broader picture" provoked any angry reactions... (Note while proofreading: No reactions, neither good nor bad, I just saw.) But I hope this will be technical enough now and to the completion of this thread... I haven't found anywhere other then on the www.wonkity.com, the address that I gave above, examples for maildrop, so I hope other users will find mine useful, which will be source of content for me... I invested time and effort to arrange those lines. Just let me give you the .muttrc (and completely without the unrelated settings for this story), because the dominant talk is about the maildrop, not the other two configuration files. ----%<-------------------------------------------------------- $ cat ~/.muttrc set mbox_type="maildir" set spoolfile=imaps://me@mybox2/ set folder=imaps://me@mybox2/ set ssl_starttls=yes set ssl_force_tls=yes set imap_passive ----%<-------------------------------------------------------- What I got with that maildrop in my Dovecot, and it would need some functions set, because I used too much pastion to get same work repeated on different input, but I don't know hot to do it, and it is by no means urgent, since I achived all the refiltering and in the way I wanted it, is I decided I wanted all mail in folders by the e-mail address by which I recieve them, and used the usual List-Id header to sort mails into up to two levels deeper, exactly for the famous yukky Stasimail, oh, sorry! 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. And to check for existance I guess it's with ... ~= ( some expression) of folders, so not to get an error on every fail attempt at creating folders as Warren Block explained here: http://www.wonkity.com/~wblock/docs/html/maildrop.html#_em_maildir_em_compa… , and maybe improve those lines by using some foreach loop or some such means... Ah, notice that I start with no folder whatsoever, neither mbox not maildir type, I let the script do it all in my /home/mr! The .mailfilter settings above for maildrop upon completion of refiltering gave me, in my mutt, not going back to no GUIs no more, thanx so kindly!, but no love lost there, with all your Java and Javascript and stinking popup windows out of nowhere and rummiging in my machine which I in no way provoked, let alone initiated, and most certainly not acquiesced to...

If there is some user who would like to have any more explanaion on this, I can try and tell more, but I know most of the users here know more and can do better that I, so I leave the talk now. I'll take a few looks back to see if I got any replies, just I can't do it in very frequent periods at all. 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

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

Hello, I understand the matter of using Dovecot as a forward proxy to Gmail is very popular (and even trivial), but my lack of Dovecot experience took me to at point where I truly need your help... I'm starting my task by trying to have something simple, where I can test connectivity to Gmail by sending a telnet to our Dovecot server. The Dovecot server accepts the telnet request, but for some reason (and here I guess is something related to SSL/TLS), I can't get to Gmail.

[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,

[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

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

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

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

-----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?

[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] service anvil and ssl-params not starts with dovecot started
by Dewey Du 28 Sep '13

28 Sep '13

Hi My dovecot started with the error below. What's the most possible reason for the error? “2013-08-28 11:41:40 ”master: Info: Dovecot v2.2.5 starting up (core dumps disabled) “2013-08-28 11:42:00 ”anvil: Fatal: Error reading configuration: Timeout reading config from /var/run/dovecot/config “2013-08-28 11:42:00 ”master: Error: service(anvil): command startup failed, throttling for 2 secs “2013-08-28 11:42:00 ”ssl-params: Fatal: Error reading configuration: Timeout reading config from /var/run/dovecot/config “2013-08-28 11:42:00 ”master: Error: service(ssl-params): command startup failed, throttling for 2 secs Actually, After dovecot starts, I can telnet 110, but it takes 30seconds or so to get through the authentication. I suspect whether the error above cause the issue or not.

[Dovecot] v2.2.6 released
by Timo Sirainen 27 Sep '13

27 Sep '13

http://dovecot.org/releases/2.2/dovecot-2.2.6.tar.gz http://dovecot.org/releases/2.2/dovecot-2.2.6.tar.gz.sig I didn't have time to look into the latest reported dsync replication bugs, but this release should have been done a long time ago already and I'm busy for next few days, so no more waiting. Things seem to be working quite well in general though. * acl: If public/shared namespace has a shared subscriptions file for all users, don't list subscription entries that are not visible to the user accessing it. + doveadm: Added "auth lookup" command for doing passdb lookup. + login_log_format_elements: Added %{orig_user}, %{orig_username} and %{orig_domain} expanding to the username exactly as sent by the client (before any changes auth process made). + Added ssl_prefer_server_ciphers setting. + auth_verbose_passwords: Log the password also for unknown users. + Linux: Added optional support for SO_REUSEPORT with inet_listener { reuse_port=yes } - director: v2.2.5 changes caused "SYNC lost" errors - dsync: Many fixes and error handling improvements - doveadm -A: Don't waste CPU by doing a separate config lookup for each user - Long-running ssl-params process no longer prevents Dovecot restart - mbox: Fixed mailbox_list_index=yes to work correctly

[Dovecot] Index error copying compressed message

Hi. Dovecot 2.2, with the zlib plugin, I think we're getting bad index entries on IMAP COPY.

[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?
