10 Apr '14

Hello list. Anybody having experience with the Apple Extensions for Dovecot at http://www.opensource.apple.com/source/dovecot/dovecot-239.8/dovecot/src/im… ? Is it possible to patch the Dovecot source with them and get them to work on a Non-Apple System? Cheers, Volker —— Volker Schwaberow Email: volker(a)schwaberow.de

[Dovecot] replication + attachment sis + zlib bug ? (HEAD version from xi.rename-it.nl)

[Dovecot] dsync deleted my mailbox - what did I do wrong?
by Benjamin Podszun 10 Apr '14

10 Apr '14

Hi. Mostly annoying: I migrated from one machine to another, made sure the target host worked as expected, updated mx records and - after a couple of days - signed it off as good. This is just my private machine, no big deal if something goes wrong.. Everything's fine? Good, let's migrate my inbox from the old machine. There's no direct connectivity between those servers, so what I did was: (old server) sudo -u vmail dsync -u dar(a)darklajid.de backup maildir:/tmp/mail_backup/ Works fine, got my maildir. Tar'd it up, moved it to the new server. Now how do I import those mails? Ah, let's use the same command, with -R? (new server) sudo -u vmail dsync -u dar(a)darklajid.de -R backup maildir:/tmp/mail_backup Error: Mailbox INBOX sync: mailbox_delete failed: INBOX can't be deleted. Wait. What? Sure enough, the last couple of days are gone, the target mailbox is completely empty. I read the man page over and over again, but failed to see the problem. I even thought for a moment that _maybe_ dsync backup is one-way only (even if that failed as well) and tried the same command with mirror. Exactly the same output, same result, empty target mailbox. In the end I succeeded to import the mails with doveadm import, completely lost a number of days of mails. My fault, sloppy not to back the up again, but I still don't think that this should happen. Ever. My question now is: - where did I fail (ignoring the backups, please. That's .. something I know) - Can I use dsync ... for backups? I don't think that this is a good idea after yesterday night? - Should dsync EVER try to delete mailboxes? Even 'special' mailboxes? Should it warn about that, asking for a --force switch or something? Any insights would be appreciated. At this point the damage is done, but I'd like to learn how to do better. Ben

[Dovecot] integration of old mails into new dovecot Maildir
by K. C. Mohan - Personal 10 Apr '14

10 Apr '14

I just installed dovecot 2.2.9 on to a new server and want to transfer all the old mails into the email accounts I imported from the previous server into MySQL database. I am not able to view the subfolders and or old mails that I copied into their respective maildir folders. I was very much appreciate if anyone could let me know how to import old mails into the new server. All I see, is the new mails that have come into the account since I started dovecot service in the new server. --- This email is free from viruses and malware because avast!

[Dovecot] Heartbleed openssl vulnerability?
by John Rowe 10 Apr '14

10 Apr '14

Do we know if dovecot is vulnerable to the heartbleed SSL problem? I'm running dovecot-2.0.9 and openssl-1.01, the latter being intrinsically vulnerable. An on-line tool says that my machine is not affected on port 993 but it would be nice to know for sure if we were vulnerable for a while. (Naturally I've blocked it anyway!). Thanks John

[Dovecot] Director NFS backups
by Murray Trainer 10 Apr '14

10 Apr '14

Hi All, What is the recommended method of taking backups of user mailboxes when using the Director setup with NFS backend mail storage? Is there any way to avoid the likely NFS locking issues by backing up the filesystem directly or do I have to do some sort of dsync method. If I have to use dsync can I dsync the mailboxes to compressed copies of the mailboxes without requiring another dovecot server to do the dsync. Thanks for you responses. Murray

That ought to be the default: http://wiki2.dovecot.org/POP3Server (Section Session locking) Did you set pop3_lock_session=yes somewhere? Locking is good if the client connection is stable: if you disable locking, you could end up with a scrambled mailbox as two or more users access it at the same time.

[Dovecot] Override maildir for just a few users
by Charles Marcus 10 Apr '14

10 Apr '14

Hi all, Currently, I have mail_location = maildir:~/Maildir set and all passdb and userdb lookups are SQL based (doveconf -n pasted below). However, I want to override the users maildir location - and *only* the maildir location - for just a few users. I was thinking the easiest way would be to add a simple flat file based userdb that is checked before the SQL based one, where I can define a different maildir for these users. So, basically, dovecot checks the flat file first, and if the user isn't found, falls back to SQL. I still want all AUTH to go through SQL... It seems like this should be fairly simple, but after reading the wiki for a few days, I'm just not sure... This is on a production box, so I have to be careful (note to self - MUST set up testing box for things like this)... Is anyone else doing anything like this, and if so would you be willing to share sanitized configs? Thx, -- Best regards, Charles

[Dovecot] Sieve (randomly?) flagging messages as \\Seen \\Deleted
by Emanuele Balla (aka Skull) 09 Apr '14

09 Apr '14

Hi, I'm trying to debug (without great results, so far) a very weird behaviour in my environment. Sorry if this came out in another form before, but I've not been able to find out anything resembling what I'm experiencing, so far... OS is a debian wheezy and dovecot is the version provided by the OS: # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-4-amd64 x86_64 Debian 7.4 The system uses postfix with virtual users, credentials and maildir locations stored on mysql, local delivery through LMTP and sieve+managesieve available to users (although managesieve only listens on localhost and is only usable through the webmail interface). FWIW, I've been running 10-20 systems just like this one (mostly with earlier dovecot versions and using LDA when LMTP wasn't available yet) for many years, and this is the very first time I'm so puzzled I end up searching for help here :-| Even though the system has been working for months (more or less 1 year now) without big changes, a strange behaviour appeared (or became evident enough to be noticed) in the last few days, apparently involving sieve and some sort of "default/hidden" action triggered by something. Or at least that's what I ended up supposing. The problem in short: Messages I expected to find in certain folders were simply not there, although sieve logs reported them as delivered in those same folders. By manually inspecting the maildir, I actually found the messages, but they were all flagged as \\Seen + \\Deleted and therefore not displayed by the MUA (ThunderBird in my case). I initially supposed this to be a TB issue, 'cause nothing in my sieve script ever flags messages that way, but I could not find anything on my client explaining that. Then I received a notification from one of my users saying he was experiencing exactly the same, except he's using mutt as IMAP client; that restricted the issue to server-side interactions only, but nothing useful could be found in logfiles... This is the "relevant" portion of a "dovecot -n" output: [...] plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_extensions = +vacation-seconds +editheader sieve_vacation_default_period = 2d sieve_vacation_dont_check_recipient = yes sieve_vacation_max_period = 30d sieve_vacation_min_period = 2s sieve_vacation_use_original_recipient = no } [...] protocol lmtp { mail_plugins = sieve hostname = alternativename.bofhland.org } There is no sieve_(before|after) script in addition to what users create for themselves. The mailboxes are relatively low-traffic; most of the traffic is caused by a single role address translated into multiple-recipients alias going to many of the users (100-300 messages per day). Almost all the users using sieve rely on it to store traffic for that role-address in a dedicated folder, including the mutt user and myself. Not that's all that important, but means that most of the misbehaviours observed (but not all) are observed in these folders. I enabled mail_debug, but there's nothing unusual in there AFAICT: it just says: - using the following location for user's Sieve script: /blabla/.dovecot.sieve - opening script /blabla/.dovecot.sieve - script binary /blabla/.dovecot.svbin successfully loaded - not saving binary /blabla/.dovecot.svbin, because it is already stored - executing script from /blabla/.dovecot.svbin - stored mail into mailbox 'DedicatedFolder' And it does, except the message happens to be flagged as seen and deleted... In order to try restricting what may be causing the issue, I added... removeflag "\\Deleted"; removeflag "\\Seen"; ...to the rule sending messages to the dedicated folder cited above for my mailbox. The problem apparently disappeared for me as long as I kept those in place. This should mean (I suppose) that the decision of flagging messages that way is taken before the users' sieve scripts are applied (sort of "hidden sieve_before"). The problem is hard to replicate as it's apparently not deterministic: the same message is being flagged for one user but not for the other, different messages between the same people and with the same thread are sometimes flagged and sometimes not. Something is surely triggering whatever is causing this, but it's not evident enough for me to point a finger and say "ha ha!" (https://www.youtube.com/watch?v=rX7wtNOkuHo) So, a question for people knowing pigeonhole's internals: does it ever choose to mark messages as described above for any reason? If yes, I may be triggering this behavior with something I recently added/modified, and at least I'll have something to focus my investigation on. :-| Any other suggestion is obviously welcome...

[Dovecot] sieve pigeonhole vacation filter responding when recipient is not explicitly listed

Hi dovecot.org, When I set up vacation filter for a mailbox, the vacation response is generated even though none of the addresses in the email are same as the mailbox address itself. I have example email sent to "aliastouser(a)mpathix.com" which gets delivered to "user(a)my.domain.com" by dovecot-lda. The invocation command is: # /usr/lib/dovecot/dovecot-lda \ -d user \ -f john.doe(a)somewhere.com \ -a aliastouser(a)mpathix.com \ -p /tmp/test.email # cat /tmp/test.email Message-ID: <test3> From: John Doe <john(a)somewhere.com> To: aliastouser(a)mpathix.com Subject: test3 vacation response as aliastouser This is the only line in test.email. Here is the vacation filter: if true { vacation :days 1 :addresses ["user(a)my.domain.com"] text: Please ignore this message, I am only testing vacation filter . ; } /var/log/mail.log shows that sieve vacation sends vacation, (and after succeeding attempts, discards due to already sent address) Apr 9 13:37:21 mx01 dovecot: lda(user): sieve: <test3>: sent vacation response to <john(a)somewhere.com> Apr 9 13:37:21 mx01 dovecot: lda(user): sieve: msgid=<test3>: stored mail into mailbox 'INBOX' ...

Re: [Dovecot] Heartbleed openssl vulnerability?
by Jake Alley 09 Apr '14

09 Apr '14

It's an interesting issue. In my experience "stale" passwords are rarely used to compromise systems. However, passwords tend to end up on sticky notes and even worse, in email databases regardless. As far as compromised email passwords, they seem to mostly come from infected clients and insecure public logins as far as I can tell. A server can control the later, but not the former. I know of a major accounting software that forces Admin users to change their passwords every few months under certain circumstances. Those passwords always end up in emails to fellow users, so in that case forcing people to change seems to be definitely counterproductive. IMV the moral of the story is that you can't crypt your way into a 100% secure world. You need other forms of checks & reconciliations that are disjoint from purely cryptographic infrastructure. For instance ask Mt. Gox and Bitcoin if they agree in hindsight, and Heartbleed is a very good example of this concept. Thanks, Jake On 4/9/2014 10:27 AM, Reindl Harald wrote: "change passwords from time to time is always clever" is a strawmans argument with no context to the issue, forcing people to change their passwords all the time for no good reasons leads mostly to completly insecured passwords to remember them easier or have them on a sticky on the screen or under the keyboard the word "counterproductive" describes that policies perfectly

[Dovecot] Migration to Dovecot 2.2.12 - How to trigger full site indexing
by kadafax＠gmail.com 09 Apr '14

09 Apr '14

Hi list, We are in the process of migrating our old (dovecot 1.2.4 based) mail system to the new one: - Centos 6 x86_64 - Dovecot 2.2.12 - Users in an openldap directory - clucene FTS I'm trying to trigger a full indexing for all the user and all their mailboxes (avoiding them to individually trigger it using a search within their MUA). I'm trying to use the "doveadm index" command. First question, is there some sort of 'wildcard' option for the name of the mailbox to index, as I dont know all the mailboxes's names the users have created (beside the regular Sent Inbox Trash and Drafts ? Second question I've tried: # doveadm -D index -A Sent which gave me: doveadm(root): Error: User listing returned failure doveadm: Error: Failed to iterate through some users Can the '-A' option work with ldap backend ?

[Dovecot] Dovecot LDAP issue
by Deeztek Support 08 Apr '14

08 Apr '14

Dovecot version: 2.0.19 ------------------------------------------------------- grep -v '^ *$#.*$\?$' /etc/dovecot/dovecot-ldap.conf hosts = server.domain.tld:389 ldap_version = 3 auth_bind = yes dn = vmail(a)domain.tld dnpass = somepassword base = ou=testou,dc=domain,dc=tld scope = subtree deref = never user_filter = (&(userPrincipalName=%u)(objectClass=person)(!(userAccountControl:1.2.840.113556.1.4.803:=2))) pass_filter = (&(userPrincipalName=%u)(objectClass=person)(!(userAccountControl:1.2.840.113556.1.4.803:=2))) pass_attrs = userPassword=password default_pass_scheme = CRYPT user_attrs = =home=/var/vmail/vmail1/%Ld/%Ln/Maildir/,=mail=maildir:/var/vmail/vmail1/%Ld/%Ln/Maildir ----------------------------------------------------- I'm authenticating users through AD and it seems to work with no problems. Unfortunately, when I try to send e-mail from a user who's not in the testou container I get the following error: Sender address rejected: User unknown in virtual mailbox table> #SMTP#. I'm assuming this happens because dovecot is not able to to lookup up that user since that user is outside the testou container. A lot of the AD users are in different places inside the AD structure and I need to be able to configure dovecot to look from the root of the AD structure down. I changed the base to this: base = dc=domain,dc=tld but it simply fails to lookup any users at that point. How would I go about getting dovecot to start at the top of the domain and look at every nested OU within AD? thanks a lot D

[Dovecot] Debugging doveadm expunge
by Andy Hawkins 08 Apr '14

08 Apr '14

Hi, I'm a recent convert to dovecot, and in general it is all working fine. However, I have a number of cron jobs set up to purge old messages from mailboxes. These don't seem to be doing what I would expect. Is there any way of debugging this process? Some way of seeing what messages it's checking, and why each one matches or fails to match? For example, I'm running this: doveadm expunge -u andy mailbox "News Reports" savedbefore 90d from the crontab of user 'andy'. I'd expect the specified folder to only contain 90 messages (I get one 'News Report' per day) but in actual fact there are 1428 in there! Any advice would be appreciated. Thanks Andy

[Dovecot] dsync replication questions
by Nikolaos Milas 07 Apr '14

07 Apr '14

I am running two servers with Dovecot v2.2.12 on CentOS x86_64 (5.10 and 6.5 respectively) and users are virtual over ldap. I have setup our main internal server (vmail.example.com) with dsync replication according to the first part of http://wiki2.dovecot.org/Replication. The second one (vmail1.example.com) will be the failover server which we want to be a real-time mirror (but can be manipulated directly and it should propagate changes back to vmail.example.com) When I started the server (vmail.example.com) mirroring started and completed fine (after a few hours). However, since then, I am not seeing a continued mirroring between the two. I would expect changes to one of the masters to be propagated in real time to the other - which does not happen. If I manually run (on vmail.example.com) dsync -u imaptester mirror ssh -l root vmail1.example.com dsync -u imaptester then these two accounts are synced. Question 1: Shouldn't mirroring continue automatically in real time (having configured it as in the first part of http://wiki2.dovecot.org/Replication)? If not, what should I do to enable such a real-time (or near-real-time) sync? Note that I have not configured "replication_dsync_parameters" as noted at the above page. Question 2: Where can I find documentation about "replication_dsync_parameters" and about "the doveadm sync command" (referred to at the same page)? I have not been able to locate such a documentation/wiki page. Question 2a: What do options "-d -N -l 30 -U" signify in "replication_dsync_parameters = -d -N -l 30 -U"? Thanks, Nick

[Dovecot] Dovecot IMAP Authentication issue with Vpopmail
by Arup 07 Apr '14

07 Apr '14

Hello All, i've configured a qmail server (for office) under Ubuntu 12.04 server following this guide- http://www.connor.net.au/tutorials/qmail/qmaillite/ everything working just fine except dovecot IMAP. i've followed this section for dovecot- http://www.connor.net.au/tutorials/q...te/dovecot.php<http://www.connor.net.au/tutorials/qmail/qmaillite/dovecot.php> but when i go to telnet 143 and try to login with username/password, it failed and showing error: ** BYE Internal error occurred. Refer to server log for more information.Connection closed by foreign host.* i think there may be some authentication issue with vpopmail and dovecot. POP and SMTP both working. but why not IMAP? i can't also use webmail (i.e. squirrelmail) as it don't working with IMAP. it's showing- *connection dropped by IMAP server *error while trying to login. i'm looking forward to a solution here. any qmail+vpopmail expert here? plz help. Thanks in advance. B/R

[Dovecot] Unknown setting: plugin after fresh install
by Patrik Karisch 04 Apr '14

Hi guys, I've installed dovecot 2.1.7 on a Debian Wheezy, tweaked some parameters little bit, but I can't restart it (dovecot -n also fails) and get this error: doveconf: Fatal: Error in configuration file /etc/dovecot/conf.d/90-acl.conf line 11: Unknown setting: plugin doveconf: Error: managesieve-login: dump-capability process returned 89 Wether I uncomment this plugin line, I get the error on another file (example 90-quote.conf). Seems a little bit weird. What have I done false? Thanks Patrik -- PRIVACY IS NOT A CRIME! So please encrypt your emails using PGP/GnuPG.

[Dovecot] mdbox with mail_attachment_dir per user in 2.2.12
by Pavel Stano 04 Apr '14

04 Apr '14

Hello, we have 2 netapp arrays with 2 volumes and we need to store our mail data in one or other volume for every user. We want keep data for one user in one volume only. So we would like to have 2 separate mail_attachment_dir, one on every volume. But in latest version 2.2.12 it look like it is only possible to set one global mail_attachment_dir. I have an idea with 2 separate dovecot instances per machine with different mail_attachment_dir. Or it is possible to somehow specify it per user ?

[Dovecot] imap / IPv6 problems?
by Egbert 04 Apr '14

04 Apr '14

Hi, I have this intermittant problem. When sending an email it *sometimes* takes ages before the process finishes. The process seems to hang in moving the message to the sent items" folder". When I disable the IPv6 stack in the network config (this is MS Windows 7), the hanging process immedialetely completes! This makens me think that is has to do with the IP stacks. Another observed effect is a long "rotating wheel" when just klicking on an imap folder before the listing in the right pane updates. Here the same trick solves the problem. I use Thunderbird on W7 as client and have my mail (3 accounts) on a remote mailserver. I have full control over that server which can become handy... Th emailserver is Ubuntu 12.04 LTS with postfix and Dovecot (2.0.19) from the standard repo's. My IPv6 connections is a native IPv6 from my ISP (xs4all.nl). I have no reason to think that the IPv 6 connecition itself is the problem. Any advise to investigate this problem is welcome. Egbert Jan, NL
