Help with installing Apache Solr with Dovecot 2.2
by Kev Lau 03 Jan '15

03 Jan '15

Hi, I am relatively new to Apache Solr and I am trying to get it to integrate with Dovecot 2.2 running on Ubuntu 14.04 and needed a little help with configuration. The following steps I have already configured. Appreciate if someone could help, so please help me! 1. Apache Solr installed, up and running 6406 [main] INFO org.eclipse.jetty.server.AbstractConnector ? Started SocketConnector@0.0.0.0:8983 I can then ssh into it and see the running solr admin. ssh -t -L 8983:localhost:8983 user(a)mydomain.com 2. Schema file added startTime: 3 minutes ago instanceDir: /opt/solr/solr/collection1/ dataDir: /opt/solr/solr/collection1/data/ In my collection1 core selector I have the following files:- 1.solrconfig.xml 2.schema.xml The output of schema.xml is shown below:- <?xml version="1.0" encoding="UTF-8" ?>  <schema name="dovecot" version="1.5"> <field name="_version_" type="long" indexed="true" stored="true"/> <field name="_root_" type="string" indexed="true" stored="false"/> <types>  <fieldType name="string" class="solr.StrField" omitNorms="true"/> <fieldType name="long" class="solr.LongField" omitNorms="true"/> <fieldType name="slong" class="solr.SortableLongField" omitNorms="true"/> <fieldType name="float" class="solr.FloatField" omitNorms="true"/> <fieldType name="boolean" class="solr.BoolField" omitNorms="true"/> <fieldType name="text" class="solr.TextField" positionIncrementGap="100"> <analyzer type="index"> <tokenizer class="solr.WhitespaceTokenizerFactory"/> <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt"/> <filter class="solr.WordDelimiterFilterFactory" generateWordParts="1" generateNumberParts="1" catenateWords="1" catenateNumbers="1" catenateAll="0"/> <filter class="solr.LowerCaseFilterFactory"/>  <filter class="solr.SnowballPorterFilterFactory" protected="protwords.txt"/> <filter class="solr.NGramFilterFactory" minGramSize="3" maxGramSize="15"/> <filter class="solr.RemoveDuplicatesTokenFilterFactory"/> </analyzer> <analyzer type="query"> <tokenizer class="solr.WhitespaceTokenizerFactory"/> <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true"/> <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt"/> <filter class="solr.WordDelimiterFilterFactory" generateWordParts="1" generateNumberParts="1" catenateWords="0" catenateNumbers="0" catenateAll="0"/> <filter class="solr.LowerCaseFilterFactory"/>  <filter class="solr.SnowballPorterFilterFactory" protected="protwords.txt"/> <filter class="solr.RemoveDuplicatesTokenFilterFactory"/> </analyzer> </fieldType> </types> <fields> <field name="id" type="string" indexed="true" stored="true" required="true" /> <field name="uid" type="slong" indexed="true" stored="true" required="true" /> <field name="box" type="string" indexed="true" stored="true" required="true" /> <field name="user" type="string" indexed="true" stored="true" required="true" /> <field name="hdr" type="text" indexed="true" stored="false" /> <field name="body" type="text" indexed="true" stored="false" /> <field name="from" type="text" indexed="true" stored="false" /> <field name="to" type="text" indexed="true" stored="false" /> <field name="cc" type="text" indexed="true" stored="false" /> <field name="bcc" type="text" indexed="true" stored="false" /> <field name="subject" type="text" indexed="true" stored="false" /> </fields> <uniqueKey>id</uniqueKey> <defaultSearchField>body</defaultSearchField> <solrQueryParser defaultOperator="AND" /> </schema> 3. Dovecot package dovecot-solr installed 4. Dovecot configured with following files to run on solr-fts. In 10-mail.conf:- # Space separated list of plugins to load for all services. Plugins specific to # IMAP, LDA, etc. are added to this list in their own .conf files. #mail_plugins = mail_plugins = fts fts_solr In 90-plugin.conf:- plugin { fts = solr fts_solr = break-imap-search url=http://localhost:8983/solr/ } I would really appreciate if someone could please help me here. Request for someone to guide me here. Thanks a lot Kevin

Disabling compressed storage for one public namespace - is it possible?
by Marc Stürmer 02 Jan '15

02 Jan '15

Greetings, I've got Dovecot 2.2.X running with gzip compressed storage enabled by default. My question though is: is it possible to disable this compressed storage for one specific, public namespace only? I haven't found quite much information about it on the wiki. Thanks in advance.

dovecot 2 low TCP speed (fetching big mail)
by Wojciech Puchar 02 Jan '15

02 Jan '15

i use dovecot 2 under FreeBSD (dovecot2-2.2.15 compiled from ports). tried both with kqueue enabled or not. everything works very fast, EXCEPT fetching big mail. tried multiple clients (thunderbird on windows, alpine on the same server, alpine on other unix server connected by 1Gb/s LAN) and fetching peaks at 1MB/s. NO SSL! could you please point me where to search for a problem. hints: writing over IMAP (eg. writing to Sent folder) works at full speed. Doesn't seem like a problem with unix server, every other service goes at speed 70-100MB/s both directions (like samba, ftp). tried to turn off "kqueue" compile time option, no difference. Please give me a hint at least what to check. Does dovecot use other way to sent data over TCP socket than other programs? thank you.

Postfix and Dovecot SASL - wiki update
by Dan Langille 01 Jan '15

01 Jan '15

I wanted to mention I updated the Postfix and Dovecot SASL wiki entry yesterday. http://wiki2.dovecot.org/HowTo/PostfixAndDovecotSASL The entry: submission inet n - - - - smtpd was incorrect. It should be: submission inet n - n - - smtpd By specifying n for chroot, it ensures that DNS lookups can occur. Otherwise, if you are using reject_unknown_recipient_domain the following error will occur: Recipient address rejected: Domain not found Hope that helps. — Dan Langille http://langille.org/

Authenticating Virtual Users without domain
by Leon Kyneur 31 Dec '14

31 Dec '14

Hi, I'm trying to migrate a large number of users to a new Dovecot cluster. The existing mail system allows a user to authenticate with a bare username if they have connected to the correct local IP on the server. e.g. imap.somedomain.com = 1.1.1.1 imap.anotheromain.com = 2.2.2.2 charlie@somedomain can authnenticate as 'charlie' or 'charlie(a)somedomain.com' as long as he is connected to imap.somedomain.com (1.1.1.1) likewise for bare usernames if they connect to imap.anotherdomain.com. A previous colleague actually achieved this by hacking with the Dovecot source code and writing in a lookup table feature. The code is very old and won't patch cleanly to the latest 2.2.15 source. Another platform we are using (commercial product) also has this feature but we also need to migrate these users to Dovecot. I already have a Dovecot proxy layer for mailbox lookup - so ideally I would like to do this on my Dovecot proxies. I know I can also do this kind of thing if I swapped my dovecot proxy for Perdition, however I don't really want to do that. I've looked into checkpassword scripts and could possibly make something work (albeit ugly) - is this the right direction to take here? Thanks, Leon

Segmentation fault in pigeonhole lib-sieve
by Orion Poplawski 31 Dec '14

31 Dec '14

The sieve plugin for Thundirbird likes to rapidly compile work in progress sieve scripts to continually give feedback on any errors in the script. This can trigger segmentation faults in lib-sieve with certain pathologically incomplete sieve scripts. One example: #0 tag_comparator_validate (valdtr=0x7f291aa713a0, arg=0x7fff5c3cfa58, cmd=0x7f291aa69360) at sieve-comparators.c:143 143 if ( (*arg)->type != SAAT_STRING ) { Missing separate debuginfos, use: debuginfo-install bzip2-libs-1.0.6-12.el7.x86_64 glibc-2.17-55.el7_0.3.x86_64 sssd-client-1.11.2-68.el7_0.6.x86_64 zlib-1.2.7-13.el7.x86_64 (gdb) list 138 *arg = sieve_ast_argument_next(*arg); 139 140 /* Check syntax: 141 * ":comparator" <comparator-name: string> 142 */ 143 if ( (*arg)->type != SAAT_STRING ) { 144 sieve_argument_validate_error(valdtr, *arg, 145 ":comparator tag requires one string argument, but %s was found", 146 sieve_ast_argument_name(*arg) ); 147 return FALSE; (gdb) print arg $1 = (struct sieve_ast_argument **) 0x7fff5c3cfa58 (gdb) print *arg $2 = (struct sieve_ast_argument *) 0x0 So sieve_ast_argument_next() is returning NULL and we're trying to dereference it without checking.

PAM issues on OS X Yosemite
by Markus Mayer 30 Dec '14

30 Dec '14

Hi, I have been running dovecot successfully on OS X Mavericks for several months. After upgrading to Yosemite, however, PAM authentication for dovecot is failing. Or rather, creating the PAM session is failing. Either way, I can't get to my e-mail. $ /usr/pkg/sbin/dovecot --version 2.2.15 $ /usr/pkg/sbin/dovecot -n # 2.2.15: /usr/pkg/etc/dovecot/dovecot.conf # OS: Darwin 14.0.0 x86_64 hfs auth_debug = yes auth_verbose = yes mail_location = maildir:/Volumes/Secure/%u/Maildir 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 = session=yes dovecot driver = pam } ssl_cert = </usr/pkg/etc/openssl/certs/dovecot.pem ssl_key = </usr/pkg/etc/openssl/private/dovecot.pem userdb { driver = passwd } $ defaults read "/System/Library/CoreServices/SystemVersion" ProductVersion 10.10.1 Dec 30 13:21:47 my.host.name dovecot[49247]: auth: Debug: auth client connected (pid=49289) Dec 30 13:21:51 my.host.name dovecot[49247]: auth: Debug: client in: AUTH 1 PLAIN service=imap secured session=3bBdlHULNgAAAAAAAAAAAAAAAAAAAAAB lip=::1 rip=::1 lport=143 rport=52278 resp=<hidden> Dec 30 13:21:51 my.host.name dovecot[49247]: auth-worker(49286): Debug: pam(markus,::1): lookup service=dovecot Dec 30 13:21:51 my.host.name dovecot[49247]: auth-worker(49286): Debug: pam(markus,::1): #1/1 style=1 msg=Password: Dec 30 13:21:51 my.host.name dovecot[49247]: auth-worker(49286): Error: pam(markus,::1): pam_open_session() failed: session failure Dec 30 13:21:53 my.host.name dovecot[49247]: auth: Debug: client passdb out: FAIL 1 user=markus It does successfully verify my password. If I purposefully enter a wrong password the error becomes "pam_authenticate() failed: authentication error (password mismatch?)". So that portion is okay. Do you have any suggestions how I might find out why pam_open_session() is failing? The auth process *is* running as root. I have tried these two PAM configurations. The first one based on Maverick's /etc/pam.d/login and used to work fine on Mavericks. # dovecot: auth account password session auth optional pam_krb5.so use_kcminit auth optional pam_ntlm.so try_first_pass auth optional pam_mount.so try_first_pass auth required pam_opendirectory.so try_first_pass account required pam_nologin.so account required pam_opendirectory.so password required pam_opendirectory.so session required pam_launchd.so session required pam_uwtmp.so session optional pam_mount.so I tried to simplify it by using the one suggested on dovecot's PAM wiki. # dovecot: auth account password session auth required pam_opendirectory.so try_first_pass account required pam_nologin.so account required pam_opendirectory.so password required pam_opendirectory.so On Yosemite, neither works. Or, quite possibly, both configurations are fine and the problem lies elsewhere. Any pointers would be greatly appreciated. In the mean time I'll be using auth-passwdfile, since that works. Thanks, -Markus

SPECIAL-USE again
by Peter Mogensen 30 Dec '14

30 Dec '14

Hi, Great to see Thunderbird support SPECIAL-USE now. I would like to hear the list about the intended use of SPECIAL-USE. I get the impression from several earlier mails here that the intention is for the server to globally decide what the folder-name of a specific SPECIAL-USE folder is for all users. That's the way the documentation exemplifies it and what I get from posts like this: http://www.dovecot.org/list/dovecot/2013-February/088129.html I get the point that if *all* clients ignored the real folder-name and only obeyed SPECIAL-USE, the clients could locally in the GUI decide language and name of the \Sent, \Drafts, \Trash folders. And the real folder name would become just an opaque identifier. However that's not how the world is like. There are plenty of clients ignoring SPECIAL-USE and placing meaning in the actual folder name in a language of their own choice. It seems natural for me to let the user configure their own individual SPECIAL-USE tagging according to their language and/or mix of IMAP clients. - either by setting IMAP METADATA (RFC5464) or by having the userdb return entries like: "namespace/inbox/Papperskorg/specialuse=\Trash" (for a swede) /Peter PS: Also... Isn't there a need for a Sieve extension to allow "fileinto" to target a folder based on special-use ?

Re: doveadm pw generates different hash each time it is invoked

What on earth is going on here? There must be something > fundamental that I am missing. "doveadm pw" is working correctly. CRAM-MD5 and SSHA use hashing in 2 different ways to authenticate a user. CRAM-MD5 is a challenge-response system where the server sends the client a random string each and every session. The client hashes the password and the random string and sends it to the server as proof of authenticity. The server performs the same calculation to verify. However, the server needs to know the password (or password equivalent) in order to duplicate the hash calculation. SSHA precomputes the random strings (salt) and hashes the password with it, and stores both salt and hash in the password database. During authentication, the password is (or ought to be) transmitted plain within a SSL connection from the client to the server, then the server hashes the password with the stored salt and compares with the hash in the database. Every time you run "doveadm pw -s sha" a new random salt is generated, hence a new hash is produced even though you use the same password. You would use challenge-response in situations where the communication channel is insecure (i.e. non-SSL). However, the drawback is the password database contains enough information for someone to authenticate if it should fall into the wrong hands. Joseph Tam <jtam.home(a)gmail.com>

The problem with "slowness" is that it can result from just about anything. I've seen reports of slowness caused by LDAP handups, filesystem and I/O polling, client issues, network issues, firewall issues, anti-virus stuff, resource starvation. That's just the stuff I remember. You'll need to dig further to reduce the scope of where it can be going wrong. I would suggest getting hints from - process tracing - network snooping - logs Test if it's a mail client issue by sampling more than one mail client (or better yet, talk IMAP directly to the server via telnet or netcat and download a large piece of Email). If that provokes a problem, work your way back to the server and do the same thing on the server itself (bypassing the network stack) and see if the problem still persists. Depending on what you find out, at least you'll know which side of the fence you should be looking at. (Also, asks yourself the obvious question: did you change anything before dovecot performance went down the tubes? New hardware? Patches?) Joseph Tam <jtam.home(a)gmail.com>

Deleting files in sdbox
by Jeff Mitchell 28 Dec '14

28 Dec '14

Hello, I'm curious as to what happens if I were to manually delete files in an sdbox on the server. A long time ago -- I'm not sure how, as it was several years ago -- something happened and a number of users got a large number of mail messages duplicated. Literally duplicated -- all headers, all body content. I have a script that can find these duplicated messages (by ignoring the first few and last few lines of each message, and using SHAs to compare and find the duplicates). However, I don't see a doveadm style command to manually delete messages, except for doveadm-expunge. In the past I've used that with search queries but my experience is that trying to do many individual operations on individual files with doveadm-expunge can be quite slow. So, if Dovecot is going to just say "huh, my indexes/metadata are wrong, lemme rebuild them", I'd rather just rm the messages and let Dovecot do its thing. Again, this is with sdbox storage. Dovecot version is 2.2.9. Thanks! --Jeff

Thunderbird supports SPECIAL-USE (Merry x-mas!)
by Patrick Ben Koetter 27 Dec '14

27 Dec '14

I've waited about two years to write this mail... :) As of Dezember, 24th Mozilla Thunderbird can handle SPECIAL-USE. The patch, which adds the required functionality, has passed review and TBs nightly build was successful. The next official Thunderbird release (version 38, release date 2015-05-19) will very likely ship SPECIAL-USE included. \o/ SPECIAL USE is an IMAP extension. It means less mailbox chaos for admins. But more than that it means less configuration work and easier orientation for end users. If IMAP server and client are capable of SPECIAL-USE [1] the server may tell the client some of the folders (Inbox, Drafts, Sent, Trash etc.) are reserved for SPECIAL-USE. Any client, capable of SPECIAL-USE, may adapts its local folders to the servers view. It may map e.g. "Sent Items" to "Sent", "Deleted Items" to "Trassh" etc. pp. All this takes place automatically. No more user interaction. No more locale problems. When all components - server, desktop-, webmail-, and mobile client - can handle SPECIAL-USE live becomes easier. Clients don't create their own 'special folders'. They understand special folders already exist and adapt. No more superfluous ambiguous folders. Users will know where their messages have been stored. Note: Combined with automx [2] users will only have to enter their realname, mail address and (optional) password and their client will setup all the rest automatically. SPECIAL-USE started as a suggestion to friends at IETF. We sponsored its implementation in Dovecot [3], when it had become a RFC standard. Then we took out to bring it to Thunderbird. This took use longer than expected. The moment we had begun to work on it, Mozilla withdrew most people from the Thunderbird team and reassigned them to Firefox OS. Things slowed down significantly and Microsoft Outlook became the first mail client to adopt SPECIAL-USE. Two years later - together with Ben Bucksch (Thunderbird developer) - we finally succeeded and it is about time to close the RFE [4]. Nobody should have to spend more time than required to configure their client. Everyone should be able to focus on their primary goal - communication via mail. We - sys4 and our business partner Becon - sponsored SPECIAL-USE. I hope SPECIAL-USE will make your and your customers life easier. The patch just became ready for x-mas. :) p@rick P.S.

Awfully slow dovecot

Hi, We’re using dovecot 1.0.7, which seems to be the latest version available on CentOS 5. Downloading emails are dead slow. Really small emails goes quickly, but normal emails and emails with attachments are so slow to download it’s almost ridiculous.

doveadm pw generates different hash each time it is invoked !?
by reik red 26 Dec '14

26 Dec '14

I am absolutely dumbfounded by "doveadm pw". My understanding is that the command should be used to create a hashed password that should in turn be placed into /etc/dovecot/passwd Here comes the "dumbfounded" part. I was creating a new virtual user, running doveadm pw to generate the hashed password. But when I tried to login via imap, the password was rejected. So I started checking that I had populated /etc/dovecot/passwd with the correct values, and in the process I ran "doveadm pw" again to make certain I had not accidentally pasted the wrong value along with a username. (I'm re-submittting after setting up a subscription, so I don't have to wait for the moderator) , What happened next surprised me greatly: if I specify "-s ssha", the resulting hashed password changes each time I invoke "doveadm pw", but if I do not specify the hashing method, I get the same password each time (as I expect). What on earth is going on here? There must be something fundamental that I am missing. ============================================== Illustrative example: machine(user) 6136 > doveadm pw -u joebob Enter new password: Retype new password: {CRAM-MD5}00747cf2ffaf11c5ea4a64979c3901fc1d20dee13f480bb598f7d8575b23e61b machine(user) 6137 > doveadm pw -u joebob Enter new password: Retype new password: {CRAM-MD5}00747cf2ffaf11c5ea4a64979c3901fc1d20dee13f480bb598f7d8575b23e61b #SAME, as expected machine(user) > doveadm pw -u glorg Enter new password: Retype new password: {CRAM-MD5}00747cf2ffaf11c5ea4a64979c3901fc1d20dee13f480bb598f7d8575b23e61b #another surprising behavior: The (virtual) username specified does not affect the hash!!! machine(user) 6138 > doveadm pw -u joebob -s ssha Enter new password: Retype new password: {SSHA}AtjINkQra967qIhU6khRED4U1x3aKwDi machine(user) 6139 > doveadm pw -u joebob -s ssha Enter new password: Retype new password: {SSHA}fZiFlHPKDn6ESM/gnUIcjJ14hRlH10DV # DIFFERENT, very unexpected ============================================== I'm on fedora 19, using dovecot.x86_64 version 1:2.2.15-1.fc19 per yum.

director + lmtp + ldap user
by Lazy 25 Dec '14

25 Dec '14

Hi, recently I have migrated our prevoius dovecot-lda to 2.2 with director + lmtp. And we are having some issues. When lmtp delivers to ldap uid names everything works except sieve vacation (login is not found in headers so reply is not sent). When using full email addresses in rcpt to vacation works but usernames are inconsistent (one user can login using his email address, or aliases, or uid). To fix that in ldap settings a have added uid=user which should be setting the username to approperate values. Most of the times it works but some deliveries are using email addresses not ldap uid's which seems to break dict quota's. It's must be related to auth cache (flushing the cache fixes the issue temporarly for given account). I think that the cache can be "polluted" by some other dovecot service. Does anyone have an idea where this can be comming from ? doveadm auth lookup -f user mon(a)test.com returns expected ldap uid no email address Thanks in advance for any help.

Maildir permissions on creation?
by Von Random 24 Dec '14

24 Dec '14

Hello. In my configuration dovecot reads home from mysql and uses no variables within it. It uses Maildir++ storage with virtual users. I also happen to use LMTP. I want to use a backup solution that does not involve running itself as root. Neither do I want to run it as dovecot's mail user. And there lies the problem: dovecot creates maildirs with 0700 and files within them inherit that set of permissions. And there seems to be no sane way to control it. I think I've figured out what to patch in order to change that default, but if possible, I'd like to avoid doing that. tl;dr: is it possible to change the default set of permissions for new maildirs created by dovecot?

Configuring LMTP/IMAP proxy
by Le Moing, Guenhaël 23 Dec '14

23 Dec '14

Hi, First, my version: [root@centos1 conf.d]# dovecot --version 2.2.15 [root@centos1 conf.d]# I have already configured dovecot that way (on one single VM, so everythinh is stored on the same machine) - A post fix server sending out to LMTP - LMTP is the dovecot LMTP server, configured with "lmtp-proxy= no", - LMTP checks the users receiving messages by using Linux passwd file "userdb" section in auth-passwdfile.conf.ext, - IMAP LOGINS are authenticated using DIGEST-MD5 also configured in auth-passwdfile.conf.ext : - # Authentication for passwd-file users. Included from 10-auth.conf. # # passwd-like file with specified location. # <doc/wiki/AuthDatabase.PasswdFile.txt> passdb { driver = passwd-file args = scheme=DIGEST-MD5 username_format=%n /etc/dovecot/users.DIGEST-MD5 #args = scheme=CRAM-MD5 username_format=%n /etc/dovecot/users.CRAM-MD5 } userdb { driver = passwd # Default fields that can be overridden by passwd-file #default_fields = quota_rule=*:storage=1G default_fields = uid=root gid=root home=/home/%n # Override fields from passwd-file #override_fields = home=/home/virtual/%u } This works fine, I can send messages through SMTP, and read them using IMAP access. But now, I woukd like to have amore structured architecture with : - A LMTP server configured as PROXY : has to identify the user, and proxy the request to the backen LMTP server (where its mailbox will stand) - On backend, I also have to start another LMTP serevr, but not configured in proxy mode of course, - Same for IMAP : IMAP proxy first checking LOGIN credentials, and then forwarding to IMAP server running on backend. As a first step, I would like to continue using my files to authenticate uses (so passwd file , and users.DIGEST-MD5), but final goal will be using a MySQL DB. So my main question are : 1) I just made a test and changed "lmtp_proxy" to "yes" in my 20_lmtp.cong file, but, strangely, this did not cah nge anything ! The LMTP process still receives mails and stores them on the local host , 2) Are there any documentation describing this process in details ? I only found some pieces on wiki pages, but not enough unfortunately ... 3) Are there some configuratiion files ready to use for my configuration. Thanks in advance. Cordialement. Guenhaël.

zlib, mdbox and spam filtering scripts
by Philon 23 Dec '14

23 Dec '14

Hi all, I am quite happily running a dovecot setup with maildirs. This was once running courier but since the migration I have never ever looked back. Now, with growing userbase I’m looking into using zlib compression and mdbox instead of maildir. This seems to go quite well using dsync on a testbed server. So let’s go production! Before final decision I came across this: - I’m using a spam learning address, where users forward their mails to train SpamAssassin. - there is a cron script on the server, mime-stripping the attachments and feeding them into SA - works quite well even for the still numerous POP users So well… compression ok, I could add a gunzip into the script and go from there. But mdbox seems only accessible via dovecot. I don’t think that accessing via IMAP makes sense for a local script. So I would block myself out when using mdbox. How are your spam/ham training routines? How do you feed SA? thank you! Philon

Hello I have a problem with lmtp delivery to usernames with '-' char. Everythong after - is ignored. when delivering to test-test2 the error message is. User doesn't exist: test I suspect this is a sideefect of auth_username_format = %Lu I have tried %Ln without success. Imap works without problems for those users. How can I disable this mapping for lmtp and use verbatim username for lookup. Thanks in advance for any answers.

LDAP: Connection appears to be hanging, reconnecting
by Matthias Egger 17 Dec '14

17 Dec '14

Hello List I have a strange problem here which i try to analyse, but i'm stuck. Maybe someone has a hint? What happened: A few weeks ago one of the LDAPS Servers which is not maintained by us has crashed. From that moment on, users could still login to check their emails, but they were not able to send any email through postfix (which uses smtpd_sasl_type = dovecot) What i do not understand, is why did dovecot not switch to the second configured LDAPS Server? It looks like it retried for ever to reconnect to the crashed LDAP Server. From the moment of the crash we see a lot of Errors like these in our logfiles: Nov 30 16:51:53 servername dovecot: [ID 583609 mail.error] auth: Error: ldap(userone,USERS_IP1,<WKiTeBUJQQBUSAnE>): Connection appears to be hanging, reconnecting AND Nov 30 16:51:59 servername dovecot: [ID 583609 mail.error] auth: Error: plain(usertwo,USERS_IP2,<QgJvcBUJqABTTWrJ>): Request 1982.83548 timed out after 151 secs, state=1 The used dovecot version is 2.2.13, runs on a solaris 10 system and the configuration for passdb and userdb are: passdb { args = /etc/dovecot-ldap.conf default_fields = deny = no driver = ldap master = no name = override_fields = pass = no result_failure = continue result_internalfail = continue result_success = return-ok skip = never } userdb { args = /etc/dovecot-ldap.conf default_fields = driver = ldap name = override_fields = result_failure = continue result_internalfail = continue result_success = return-ok skip = never } And the dovecot-ldap.conf contains (obfuscated): uris = ldaps://server2.tld ldaps://server1.tld ldaps://server4.tld ldaps://server3.tld dn = ... dnpass = ... ldap_version = 3 auth_bind = yes base = ... scope = onelevel user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid user_filter = ... pass_attrs = uid=user pass_filter = ... The strange thing is, that with the very same binaries and configuration (okay, some minimal modifications have been made to bind to the correct interfaces...) a test on our testsystem works as it should. When we shutdown slapd, dovecot recognizes it an connects to the alternate LDAPS. When we shutdown slapd and start a netcat (just to let something listening without responding)... you guess it. Dovecot does recognize it and switches over to the alternate testsystem. So on our testsystem, everything worked as it should. But the productive system did not. And since the LDAPS are not maintained by us it is somewhat hard to try to reproduce something. At least i got the logfiles from server2.tld and server1.tld. But they only show what i still knew. Our server connected to server2.tld until the crash happened. But server1.tld never got any connection. Has someone an idea what i could try to find out why dovecot did not switch to server1.tld?

dsync summary?
by Randall Gellens 17 Dec '14

17 Dec '14

Is there a way for dsync to report a summary of what it did? For example, when finished, it could report how many messages in how many folders were added (or deleted for a two-way sync) or had flags modified, and if any messages/folders were skipped due to errors or whatever. This could provide a sanity check that a sync looks like it worked. -- Randall Gellens Opinions are personal; facts are suspect; I speak for myself only -------------- Randomly selected tag: --------------- Hippogriff: An animal (now extinct) which was half horse and half griffin.

replication - more than 2 servers?
by Ron Cleven 17 Dec '14

17 Dec '14

We tested dovecot for a fair amount of time and decided finally to put it into production under CentOS 7 (we are running 2.2.10). I just joined the list, so I apologize for what is probably a question that has been answered many times, but I was wondering if there are any plans to implement replication among 3 or more servers (all "masters", as with 2)? As best as I can tell, replication seems to be limited to 2 servers, and it is not obvious to me even how more than 2 would be supported syntactically in the configs. That is, what might be an example of the "mail_replica" clauses if such a thing was supported?

Problem with TLS and Outlook 2010
by Wayne Andersen 16 Dec '14

16 Dec '14

Dovecot 2.0.9 So I am trying to get my Outlook 2010 client to use TLS with Dovecot. The Outlook error that I get is: Log onto incoming mail server (IMAP): A secure connection to the server cannot be established. I have set the port to 143,993,995 none of them work, and the security to TLS. I have all of the certificates in the full chain installed on my machine and when viewing them they all show This certificate is OK. I have turned on Outlook logging and am seeing this: C:\PROGRA~2\MICROS~2\Office14\OUTLMIME.DLLIMAP: 14:48:40 [db] Intializing connection [131383B0] IMAP: 14:48:40 [db] Setting internal codepage to 1200 IMAP: 14:48:40 [db] Connecting to 'mail.mydomain.com' on port 143.

Dovecot lda Panic: file mail-transaction-log.c
by Alessio Cecchi 16 Dec '14

16 Dec '14

Hi, I'm running: # 2.2.15: /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.6 (3e924b1b6c5c+) # OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0.10 with mailbox in Maildir format and LDA to delivery new email (+ sieve for filter) on the server there is an email account that is used for "archive", it only receives messages and nobody connects to it. Today dovecot was unable to delibery, via LDA, email in the Maildir and in the log i found the following error. Login via POP or IMAP works fine but is impossibile to delivery new email (the INBOX have about 135000 emails). I have delete all files in Maildir except cur/ new/ tmp/ and rebuild the dovecot cache, but the error is the same. Could be a sieve problem? In the user's home there was a file called .dovecot.lda-dupes.lock What is wrong?

Failed installation on Ubuntu with Postfix/Dovecot/Squirrelmail
by ghalvors78＠hushmail.com 15 Dec '14

15 Dec '14

Hello all, I did an install following a HOWTO document that has a fair number of positive reviews, but something went wrong along the way: https://www.digitalocean.com/community/tutorials/how-to-configure-a-mail-se… I made a couple deviations. I opted to not use StartSSL keys, and decided to stay with the default keys. Also, I chose to use Squirrelmail, but not Spamassassin. I tried to ensure that there are no issues with the Postfix installation (Dr. Venama and the team were quite helpful). I also had two Postfix book at my side, but I have none for Dovecot. While my goal is to get my server running, I would like to gain an understanding of Dovecot along the way, because sooner or later, it will break and I'll need to revisit the installation. First hint of a problem was that Squirrelmail would say the IMAP server dropped the connection on a successful login. So I went to a command line and used 'mail' to compose a test message from my laptop and see how the machine at Digital Ocean handled it. It didn't go over so well, in fact, it's generating errors as I'm writing this (every 5 minutes). For privacy, I swapped my domain name, for the generic example.com. Dec 14 20:24:18 example postfix/qmgr[13624]: EF3C0C0A17: from=<gary(a)Garys-MacBook-Pro.local>, size=597, nrcpt=1 (queue active) Dec 14 20:24:18 example dovecot: lmtp(21652): Connect from local Dec 14 20:24:18 example dovecot: lmtp(21652, bob(a)example.com) Error: user bob(a)example.com: Initialization failed: namespace configuration error: inbox=yes namespace missing Dec 14 20:24:18 example dovecot: lmtp(21652): Disconnect from local: Successful quit Dec 14 20:24:18 example postfix/lmtp[21651]: EF3C0C0A17: to=<bob(a)example.com>, relay=mail.example.com[private/dovecot-lmtp], delay=168169, delays=168169/0.01/0.01/0.01, dsn=4.3.0, status=deferred (host mail.example.com[private/dovecot-lmtp] said: 451 4.3.0 <bob(a)example.com> Temporary internal error (in reply to end of DATA command)) Now when I was checking that Postfix wasn't the likely problem, one of them mentioned: http://archives.neohapsis.com/archives/postfix/2014-12/0189.html (Postfix-users archive) that I needed: namespace inbox { inbox = yes } But I'm curious why that I'm the only one that seems to have been nailed by this omission. A keyword search on 'namespace' only brought up a single comment. What are your thoughts? Below, I appended the configuration files that I modified. I tried to compress them to a minimum space for the list by omitting the comments. # # /etc/dovecot/dovecot.conf # !include_try /usr/share/dovecot/protocols.d/*.protocol protocols = imap lmtp pop3 dict { } !include conf.d/*.conf !include_try local.conf # eof # # /etc/dovecot/dovecot-sql.conf.ext # driver = mysql connect = host=127.0.0.1 dbname=servermail user=usermail password=changed_it default_pass_scheme = SHA512-CRYPT password_query = SELECT email as user, password FROM virtual_users WHERE email='%u'; # eof # # /etc/dovecot/conf.d/10-auth.conf # !include auth-sql.conf.ext # eof # # /etc/dovecot/conf.d/10-mail.conf # mail_location = maildir:/var/mail/vhosts/%d/%n mail_privileged_group = mail # eof # # /etc/dovecot/conf.d/10-master.conf # service imap-login { inet_listener imap { port = 143 } inet_listener imaps { } } service pop3-login { inet_listener pop3 { } inet_listener pop3s { } } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { mode = 0600 user = postfix group = postfix } } service imap { } service pop3 { } service auth { unix_listener /var/spool/postfix/private/auth { mode = 0666 user = postfix group = postfix } unix_listener auth-userdb { mode = 0600 user = vmail } user = dovecot } service auth-worker { user = vmail } service dict { unix_listener dict { } } # eof # # /etc/dovecot/conf.d/10-ssl.conf # ssl=required ssl_cert = </etc/dovecot/dovecot.pem ssl_key = </etc/dovecot/private/dovecot.pem # eof Thanks for making it all the way down here!

virtual mailbox segfault
by Tóth Balázs 15 Dec '14

15 Dec '14

Hello, I have a segfault problem, and I can not resolve myself. The details below (stack trace, config....). Maybe important to reproduce, everithing working well until I connect with SoGo ActiveSync (SoGo web, and other IMAP clients are working well). So maybe the SoGo send something magical command if the user client use the ActiveSyn... (the IMAP debug attached too) Thanks, Balazs Toth Program terminated with signal 11, Segmentation fault. #0 0x000002ba68e83609 in array_count_i (array=0x52d1cf10b8) at ../../../src/lib/array.h:140

[2.3 feature request]: multiple passwords for single user
by Arkadiusz Miśkiewicz 15 Dec '14

15 Dec '14

Hi. I wonder if there any plans of finishing "multiple passwords for single user" feature? Few months old thread mentioned this: http://www.dovecot.org/list/dovecot/2014-July/097217.html and even a patch that unfortunately was never finished http://dovecot.org/patches/2.0/auth-multi-password-2.0.diff Multiple passwords for single user are great since allow easy password management for users. For example you could have one password on a laptop, one on a phone, one on a tablet. Revoking access to the device is as easy as dropping single password and it doesn't affect other devices. There are more use cases. Untill that happens (not that great) workaround exists: http://wiki2.dovecot.org/Authentication/MultipleDatabases Thanks, -- Arkadiusz Miśkiewicz, arekm / ( maven.pl | pld-linux.org )

Userdb's and IMAP proxying
by Thomas HUMMEL 15 Dec '14

15 Dec '14

Hello Timo, In order to plan a migration, I want to setup an IMAP proxy (proxy_maybe) with a dovecot server (I'm running the old dovecot-2.1.15 but I could upgrade or use a proxy only dovecot-2.2.x server)/LDAP pass et userdb's. I'm won't be in charge of the migration itself but I think the idea will be to migrate a chunk of users each night and then let the proxy send them to the new server. I wonder if, instead of altering my LDAP schema to be able to add the needed attributes (matching proxy/proxy_maybe, host, ...) I could use a second userdb (preferably in a file : passwd-file ?) only for those extra_fields (i.e. the second userdb would extend the LDAP one). As a matter of fact, I guess those who will migrate users will prefer writing to a file than to add some LDAP attribute in the user entry. In other words, can I get different extra_fields for the same user in different userdb's ? -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Groupe Exploitation et Infrastructure

Replication and Sieve

Hi, I've got two servers set up for replication, which is working fine - except the sieve scripts. While the first replication, the existing rules have been replicated well. Also the activation/Deactivation seems to work. But Changes to the rules doesn't seem to be transferred.

Can't save to folders
by Dave G. 15 Dec '14

15 Dec '14

When I login through imap, I can see everything in ~/mail/ just fine. I cannot save to any of them. If I have an autocreate-autosubscribe folder (ZZZ here), it shows up as empty (correct). Then if I save something to it through imap, a file ~/mail/ZZZ appears, but nothing actually gets saved to it.

Is the mdbox format backwards compatible?

I'm contemplating using dsync with dovecot-2.2.10 (el7) and then transferring the resulting mdbox files to a dovecot-2.0.9 (el6) server. Is the mdbox format backwards compatible between the two versions?
