[Dovecot] Strange difference between mails delivered with dovecot-lda and lmtp
by kjonca＠o2.pl 15 Mar '14

15 Mar '14

For a long time I have had configuration where mails were fetched by fetchmail then passed to exim and then passed to dovecot via lmtp. Recently I remove dovecot module and mails are passed from exim to dovecot via dovecot-lda Yesterday I have some kind of accident and lost my .fetchids file so a lot of mails were fetched again. During duplicate hunting I found something strange: messages fetched yesterday (passed to dovecot with lda have additional line) have additional line at the end: for example --8<---------------cut here---------------start------------->8--- diff cur/1392241092.M478532P15313.alfa,S=13668,W=13925:2,a cur/1394814438.M978438P14745.alfa,S=13567,W=13823:2,a 1,6c1,4 < Return-Path: <system(a)przelewy24.pl> < Delivered-To: <kjonca@localhost> < Received: from alfa.kjonca < by alfa.kjonca (Dovecot) with LMTP id p94PDcTp+1LROwAApvcrCQ < for <kjonca@localhost>; Wed, 12 Feb 2014 22:38:12 +0100 < Received: from [127.0.0.1] (port=60632 helo=alfa.kjonca) --- > Return-path: <system(a)przelewy24.pl> > Envelope-to: kjonca@localhost > Delivery-date: Fri, 14 Mar 2014 17:27:18 +0100 > Received: from [127.0.0.1] (port=45527 helo=alfa.kjonca) 9,10c7,8 < id 1WDhVU-0003ys-75 < for kjonca@localhost; Wed, 12 Feb 2014 22:38:12 +0100 --- > id 1WOUgz-00015z-L0 > for kjonca@localhost; Fri, 14 Mar 2014 17:10:41 +0100 13c11 < for <kjonca@localhost> (single-drop); Wed, 12 Feb 2014 22:38:12 +0100 (CET) --- > for <kjonca@localhost> (single-drop); Fri, 14 Mar 2014 17:10:41 +0100 (CET) 30c28 < Message-Id: <E1WDhVU-0003ys-75(a)alfa.kjonca> --- > Message-Id: <E1WOUgz-00015z-L0(a)alfa.kjonca> 256a255 > --8<---------------cut here---------------end--------------->8--- I'm somewhat confused with this.

[Dovecot] Problem with trying to use dsync with ldap userdb
by Frédéric Goudal 14 Mar '14

Hello, I'm trying to use dsync on a dovecot 2.2.12 I'm using an ldap database as a user database with the following configuration : auth_bind = yes ldap_version = 3 auth_bind_userdn = uid=%u,ou=People,dc=ipb,dc=fr user_attrs = uidNumber=uid,gidNumber=gid But I keet having the following errors : 2014-03-14 17:53:37 doveadm(XXX): Debug: user XXX: Auth PASS lookup returned temporary failure: reason=Configured passdbs don't support crentials lookups 2014-03-14 17:53:37 doveadm(XXX): Debug: auth input: reason=Configured passdbs don't support crentials lookups 2014-03-14 17:53:37 doveadm(XXX): Error: sync: /usr/local/var/run/dovecot/auth-userdb: Configured passdbs don't support crentials lookups (to see if user is proxied, because doveadm_port is set) I have been hunting through the doc for the last hours and I don't find what to change. I found something about adding set INSECURE_SETUID=1 export INSECUURE_SETUID before checkpassword-reply launch, but it does not change anything... Btw my two server have use the users uid from the ldap, but don't allow user login on the servers where only admin can log in. Does somebody has an idea where to dig ? f.g.

[Dovecot] NFS not responding generates authantication crash
by bart 14 Mar '14

14 Mar '14

I am facing dovecot authentication problems caused by unresponding NFS server. If there is even short break in communication with NFS server keeping maildirs, the dovecot generates the avalanche of processes (dovecot/imap and dovecot/pop3). The real number of connections was about 50 and after the problems occurs it rises to 1000. After about 3 hours the limit of connections is filled up: dovecot: master: Warning: service(auth): client_limit (1000) reached, client connections are being dropped and next: imap-login: Warning: Auth process not responding, delayed sending greeting pop3-login: Warning: Error sending handshake to auth server: Broken pipe imap-login: Warning: Error sending handshake to auth server: Broken pipe When the mail storage was local there was no such problem. After moving to NFS storage the problem arised when trying to make backup with dump (we switched to rsync then) or now if NFS is not responding for a while. My dovecot conf for NFS is in accordane with: http://wiki2.dovecot.org/NFS mmap_disable = yes dotlock_use_excl = no # only needed with NFSv2, NFSv3+ supports O_EXCL and it's faster mail_fsync = always mail_nfs_storage = no mail_nfs_index = no NFS shares are connected with no special parameters. Can something be done on dovecot configuration to prevent from generating those dovecot connections processes? Or is it the problem with NFS configuration? -- View this message in context: http://dovecot.2317879.n4.nabble.com/NFS-not-responding-generates-authantic… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] quota using wrong limits in user shared mailboxes
by Steffen Kaiser 13 Mar '14

13 Mar '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I have setup a shared namespace to expose user's mailboxes to other users. That works well. Via ACLs users can access other users mailboxes. I have setup a quota for each user, that works well, too. The quota is tracked and new messages are denied, if the quota is exceeded. I do not find hints, if you need to setup something special for shared namespaces. http://wiki2.dovecot.org/Quota/Configuration shows how to track the quota and http://wiki2.dovecot.org/SharedMailboxes/Shared shows how to setup the namespace and ACL. If user1 shares "mailbox" to user2 and user2 copies a message there, the quota is tracked in the quota of user1 correctly. But to calculate if * LOGIN user2 ... * COPY 1 users.user1.mailbox fails with overquota or succeed, the quota limit of user2 is used instead of the quota of user1, whom "mailbox" belongs to. I have tested it with a. limit(user2) < limit(user1) b. quota(user1) + sizeof(message) < limit(user1) if quota(user1) + sizeof(message) > limit(user2), COPY fails with overquota. If I raise the quota of user2, the COPY succeeds. That means, although the target user's quota is not exceeded and won't after the copy, COPY fails. That seems to be wrong for me. The same will apply to the other way round, I guess: If the target user is over quota, but copying user's quota limit is greater than that, the COPY succeeds. [I have not tested it.] Hence, if you enable sharing, you undermine quota, because the other user can copy messages into a mailbox of an user overquota. Does other people see the same issue?

[Dovecot] Turning on autocreate of maildirs - how?
by Graham Leggett 13 Mar '14

13 Mar '14

Hi all, I have a dovecot v2.2.7 installation, and I would like dovecot to autocreate the Maildir mailbox when those mailboxes don't exist. Following the instructions at http://wiki2.dovecot.org/MailboxSettings have had no effect, the errors below are reported. As soon as I create the Maildir manually with maildirmake fetching mail starts working fine, so all of the messages about the directory being ambiguous seem to be a red herring.

[Dovecot] Struggling with antispam
by Alan Chandler 13 Mar '14

13 Mar '14

I have a dovecot installation I am building on a raspberry pi for a mail server for the home. I am almost there, everything bar one thing is working. In simple terms dovecot is the authentication agent and the lda (using lmtp) for postfix. My maildir mailboxed at at /var/mail - location and accounts controlled by a small sqlite database. the uid for these mailboxes are 10001 and up and are not mapped to any account on the system. The sieve plugin is working and I have a default script which works to archive outgoing mail, returned via postfix sender_bcc_maps to user+saveout into a Sent subfolder organised by date. postfix also uses milters, to do spf, and dkim checking - and most importantly from this posts perspective passes all mail through dspam, adding an X-DSPAM-Signature header as it passes through. I plan to use another default sieve script to move mail based on the X-DPAM-Result header to move messages to the users Junk folder (when I can get antispam working). I want to use the antispam plugin to pick up users moving mail in and out of their Junk folder to train dspam. I initially tried using antispam's dspam backend. However I could not get it to work. I "think" the issue is that antispam is running with uid 10001 when it does this, and dspam will not process the message because it can't find this uid as a system user. But I am not sure. The approach I am trying now, is use the pipe backend to send mail to spam(a)chandlerfamily.org.uk or ham(a)chandlerfamily.org.uk - and via postfix manipulations get that to call dspam as user dspam. If I run as root and use sendmail -bv to check that it works I get a delivery report that shows that it would indeed arrive at dspam I have a file in /var/spool/dspam called group which has dpsam:shared:* In it so that all users share the same dictionary.

[Dovecot] Disable/patch iOS7 Full Body Search
by Chris Laif 12 Mar '14

12 Mar '14

As mentioned in other posts [1], iOS7 Mail App uses a multi-folder full body search by default. As to my knowledge, this behavior cannot be disabled within the Mail App. Is there any way to disable/patch this behavior on the server side? My users complain that searching now takes 'forever'. They were happy with the old behavior (searching From/To/Subject only). I do NOT want to setup/maintain a dovecot FTS. I just want to have the 'old' behavior. Chris [1 ]http://blog.fastmail.fm/2013/09/17/ios-7-mail-app-uses-multi-folder-body-searches-by-default/ ("Our plan at FastMail is to detect iOS clients, and convert all searches into FUZZY searches.")

[Dovecot] Finding memory leaks
by Philipp Brüll 12 Mar '14

12 Mar '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, I try to find a memory leak in a dovecot plugin that I develop. In order to find it, it would be helpful to print the total amount of memory that is currently allocated. This print could than spread over the source code and the memory consumption can be tracked. I've tried i_debug("pool size %u", (unsigned int)pool_alloconly_get_total_alloc_size(system_pool)); But that failed. Does someone has a good advice? I would like to avoid complex solutions like valgrind.

[Dovecot] Doveadm?
by Tommy Berglund 12 Mar '14

12 Mar '14

I have a question? Is it possible that with doveadm delete all but the last x-number of messages in a folder. For example to retain the last 200 messages in the folder. If it is possible, how do you do it? Something like "doveadm expunge -u jane.doe(a)example.org mailbox xxx" Thank you! -- //Tommy

[Dovecot] Suppress IMAP Disconnection Messages

In syslog, I frequently see messages such as: "dovecot: imap(user): Disconnected for inactivity" I understand why these happen, but is there anyway to configure logging to suppress these messages?

[Dovecot] Can I create multiple sockets and listen on them in parallel.
by Alan Chandler 11 Mar '14

11 Mar '14

I currently have a setup which is postfix -> dovecot via lmtp over a unix socket. The socket is located at /var/spool/postfix/private/dovecot-lmtp I am calling dspam as a milter from postfix. However I am struggling with getting dspam knowing the correct user for the incoming mail, because after its been through the milter, the virtual alias maps etc end up turning it into my "dovecot" user name, and the two are not easily comparable. So instead I want to try and set up postfix->dspam->dovecot But I want to take it in easy stages, and therefore ideally would like to set up dovecot to listen on two sockets simultenously = one for the existing connection from postfix, and one for the future connection from dspam - preferably in the context of the /var/spool/dspam or /var/lib/dovecot directories That way I can continue to receive existing mail whilst sending a few test mails through dspam. Does 10-master.conf config file work that way? (debian configuration) can I change something like this ... service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { mode = 0600 group = postfix user = postfix } } into this ... service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { mode = 0600 group = postfix user = postfix } unix_listener /var/spool/dspam/dovecot-lmtp { mode = 0600 group = dspam user = dspam } } and still have dovecot work? -- Alan Chandler http://www.chandlerfamily.org.uk

[Dovecot] POP3 and mail retention
by Roman Gelfand 11 Mar '14

11 Mar '14

Using outlook 2010 as mail client, I have noticed that once an email is moved from inbox, it is deleted from the cur/ directory on the server. Is there a pop3 setting on dovecot that would keep emails, with possible retention period, and recognize that this email has been moved from inbox, etc.. If all of this is doable, would setting outlook to delete the email after 14 days work? delete email from the server when emptying deleted folder? Thanks in advance

I am working on setting up dovecot 2.2.12 with an installed qmail + vpopmail 5.5.0 base. So far I have not had much luck getting the auth to work with vpopmail. Does dovecot 2.2.12 work with vpopmail 5.5.0? So far when I try to authenticate I always get back User Unknown in the log. Thanks

[Dovecot] Sieve/autosubscribe subfolder
by Moritz Augsburger 09 Mar '14

09 Mar '14

Hi, I just ran across the annoying issue, that with lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes set, parent folders of newly created subfolders get subscribed without being existent. Let me give an example: In sieve I use fileinto "foo/bar"; but "foo/" does not exist as folder. So the Mailbox "foo/bar" gets created, but without "foo/" being a Mailbox. Nevertheless gets "foo/" subscribed, so that I have a non-existing mailbox in my subscription list, what confuses thunderbird. So, to solve this problem, I would propose - either the implicit creation of foo/ as mailbox or - not subscribing foo/ Moritz

[Dovecot] Mbox corruption - Inbox beginning with 'FFrom' or 'FrFrom'
by Dimos Alevizos 08 Mar '14

08 Mar '14

Hello, we're having some problems with our dovecot setup. I've seen similar problems in the mailing list some years ago but alas wasn't able to find a solution. Our setup is as follows : An MX farm (postfix) sends mails via LMTP to a director farm (dovecot 2.1.12) which proxies pop3/imap/lmtp traffic to a dovecot farm (dovecot 2.1.16). All mailboxes and indexes are on NFS and all servers are Centos. The problem is that at times we see mailboxes (all of them are in mbox format) beginning with FFrom or FrFrom and of course dovecot says it's not a valid mbox file.

[Dovecot] Planning migration
by Alan Chandler 08 Mar '14

08 Mar '14

I think I have a working dovecot installation, and the time has come to migrate my users. There are only 4 of us, so it can be done manually per user. I looked at this page in the wiki http://wiki2.dovecot.org/Migration/Dsync but I am totally confused. 1st off, it uses doveadm, but with commands parameters that dont match my doveadm's man page. In fact they look more like dsync parameters. Is there an error, or am I totally misunderstanding 2nd - if I assume its a dsync set of parameters, the imapc: at the end is a specification of location2. However, again my man page doesn't give any explanation of this. I am wondering, is this an example of an proxy 3rd - where do the imapc_* parameters go in the configuration I can't find any reference to them in the wiki

[Dovecot] How to run a program with mail_filter plugin
by Stanislas SABATIER 07 Mar '14

07 Mar '14

Hi, I'm using mail_filter plugin but I don't want it to launch a script but a program I wrote instead. In 10-master, if I put the absolute path to my program in the plugin settings ie : (…) service mail-filter { executable = /usr/local/bin/mail/my_email_filter (…) But I've got the following error from Dovecot : dovecot: master: Error: service(mail-filter): Initial status notification not received in 30 seconds, killing the process h ow do I need to configure the service to launch my program ? Thanks, Regards, Stan. --------------------------------------------------------------- Stanislas SABATIER s.sabatier(a)pobox.com ---------------------------------------------------------------

[Dovecot] no sieve with lmtp_save_to_detail_mailbox=yes
by Dennis Kuhn 06 Mar '14

06 Mar '14

i have a problem with sieve and lmtp_save_to_detail_mailbox = yes. If the mailbox "detail" exists everything works fine, but if the mailbox detail does not exist then sieve does not work. The .dovecot.sieve.log file says sieve: info: started log at Mar 06 14:28:47. error: msgid=<531877EE.7070806(a)heinlein-support.de>: failed to store into mailbox 'test2': Mailbox doesn't exist: test2. I think this is the reason why no sieve script is executed, but why is sieve here involved? Is there any relation between lmtp_save_to_detail_mailbox=yes and sieve or is this a bug? The same sieve file works with the same mailaddress without mailextension, so the sieve script is not the reason for the failure. I am using dovecot version 2.2.12 Dennis Kuhn -- Heinlein Support GmbH Schwedter Str. 8/9b, 10119 Berlin http://www.heinlein-support.de Tel: 030 / 405051-57 Fax: 030 / 405051-19 Zwangsangaben lt. §35a GmbHG: HRB 93818 B / Amtsgericht Berlin-Charlottenburg, Geschäftsführer: Peer Heinlein -- Sitz: Berlin

[Dovecot] Still no emails since Feb. 6
by Steve Campbell 06 Mar '14

06 Mar '14

I checked my settings on the dovecot mailman page, and although my account was set to "disable" email, after changing it and attempting to have the list resend my password, I'm still not seeing emails. The last time I received emails, the outgoing server for the list was sent from the IP 193.210.130.67. Is that still correct? I've checked my logs to see if there's anything blocked, and I don't see anything. I've checked my access file and firewall, and nothing is blocked there. I'm not sure why my account settings showed "disabled", but it sounds like email was either bounced back to the list or my server is in some type of outgoing list to prevent sending to me. I'm at a loss. Is there any way an admin can check for me, please, to see if there's a problem they might spot? Thanks, steve

[Dovecot] Pigeonhole Sieve Extprograms Plugin
by dovecot＠voidptr.de 06 Mar '14

06 Mar '14

Hi, I upgraded to Dovecot 2.2.9 from Debian's wheezy-backports today (which should contain the "sieve_extprograms" plugin and thus also the vnd.dovecot.{pipe,filter,execute} capabilities. However when I add require "vnd.dovecot.filter"; to my sieve script via managesieve, the server reports error: require command: unknown Sieve capability: 'vnd.dovecot.filter' What am I missing and what should I do to get pipe/filter/execute to work? postconf -n attached.

[Dovecot] whole user mailbox read only
by Francesco 06 Mar '14

06 Mar '14

Hello, i was browsing the dovecot wiki for some documentation related to the use of ACLs but i couldn't find an answer. i'm in the need to prevent users from deleting emails, yet being able to add new content via imap, what i mean is that a user should be able to create an email in its mailbox (maildir actually is used), but once the email is there the user shouldn't be able to delete it. do you know if there is a way to accomplish this for each subfolder on a Maildir environment? Thanks in advance Francesco

[Dovecot] Shared Namespace and correct location
by Dieter Knopf 05 Mar '14

05 Mar '14

Hello again, i still have problems using a Shared Namespace in my configuration. I'm using Dovecot 2.2.9. mail_location = maildir:/home/vmail/%d/%n/MAILDIR:INDEX=/home/vmail/%d/%n/INDEX/ namespace inbox { type = private separator = / prefix = inbox = yes } This works create. But: namespace { type = shared separator = / prefix = shared/%%u/ location = maildir:/home/vmail/%%d/%%u/MAILDIR/shared:INDEX=/home/vmail/%d/%u/INDEXS/%%u subscriptions = no list = children } I'm still not sure how i can see a shared mailbox on a different account. I can add ACL rules and dovecot is adding SQL-Entries to the user-shares table. The dovecot-acl-list file is created too, hope this is okay (vfile + SQL) But i can't see the shared folder on the target account. I tried many location-pathes, but not sure how i can add the right folder. There must be a problem with %%d and %%u. Thank you very much, Dieter

[Dovecot] Dovecot Migration: Retrieving/Logging POP/IMAP Passwords in Plaintext
by Traiano Welcome 05 Mar '14

05 Mar '14

Hi List I'm currently in the process of migrating my dovecot imap/pop users to a new server and have to extract their passwords in order to import them into the new system (different password encryption schemes). I've tried enabling auth_* debug parameters in my dovecot.conf in the hope that this would result in logging plaintext passwords to the dovecot log. However dovecot does not log the passwords in plaintext under any debugging configuration. My question: Is there any other configuration of dovecot that would allow me to capture POP/IMAP passwords at a successful login time?

[Dovecot] Using AD, one more try - "successfol auth" and crashing auth process
by Jeroen Scheerder 05 Mar '14

05 Mar '14

Hi, I have no success in using AD with dovecot. The little checkpassword script I cooked up that uses ldapsearch to lookup a user DN (with an authenticated bind) and then ldapsearch with an authenticated bind for that DN again works well. * Approach 1: use a service account to bind to AD, lookup the user DN, and bind to that DN. It fails. The LDAP config looks like: hosts = dc2.office.on2it.net ldap_version = 3 base = dc=office,dc=on2it,dc=net scope=subtree auth_bind = yes dn = CN=DovecotSvc,OU=Svcs,DC=office,DC=on2it,DC=net dnpass = suppressed pass_attrs = sAMAccountName=user pass_filter = (&(objectClass=person)(sAMAccountName=%u)) user_attrs = sAMAccountName=user user_filter = (&(objectClass=person)(sAMAccountName=%u)) What happens in this case is best shown in the packet capture as displayed by tshark: $ tshark -o tcp.check_checksum:FALSE -tr -r dc2.pcap 1 0.000000 172.17.50.13 -> 172.17.10.2 LDAP 197 bindRequest(7) "CN=DovecotSvc,OU=Svcs,DC=office,DC=on2it,DC=net" simple 2 0.001879 172.17.10.2 -> 172.17.50.13 LDAP 88 bindResponse(7) success Yay! The service account binds just fine. 3 0.001967 172.17.50.13 -> 172.17.10.2 LDAP 180 searchRequest(8) "dc=office,dc=on2it,dc=net" wholeSubtree 4 0.002772 172.17.10.2 -> 172.17.50.13 LDAP 502 searchResEntry(8) "CN=Jeroen Scheerder,OU=Users,DC=office,DC=on2it,DC=net" \ | searchResRef(8) | searchResRef(8) | searchResRef(8) | searchResDone(8) success 5 0.098367 172.17.50.13 -> 172.17.10.2 TCP 66 49416 > 389 [ACK] Seq=246 Ack=459 Win=1037 Len=0 TSval=602425599 TSecr=124473537 Yay! The user DN is found successfully. 6 225.149885 172.17.50.13 -> 172.17.10.2 LDAP 166 bindRequest(12) "CN=Jeroen Scheerder,OU=Users,DC=office,DC=on2it,DC=net" simple 7 225.152323 172.17.10.2 -> 172.17.50.13 LDAP 88 bindResponse(12) success 8 225.248387 172.17.50.13 -> 172.17.10.2 TCP 66 49416 > 389 [ACK] Seq=346 Ack=481 Win=1040 Len=0 TSval=602650749 TSecr=124496053 Yay! The user DN bind works. But wait, why is it taking dovecot 225 seconds to get around to trying it? The auth process has already given up. * Approach 2: A template defines the user DN. Bind to that DN. AD DNs don't contain usernames, but AD allows all kinds of non-LDAP shorthands for DNs, inclusing %user%@domain. I've verified this to work using ldapsearch: $ ldapsearch -o ldif-wrap=no -x -LLL -E pr=200/noprompt -H ldap://dc2.office.on2it.net \ -b dc=office,dc=on2it,dc=net -s sub \ -D js(a)office.on2it.net -W \ '(&(ObjectClass=person)(sAMAccountName=js))' DN Enter LDAP Password: dn: CN=Jeroen Scheerder,DC=office,DC=on2it,DC=net The config looks like: hosts = dc2.office.on2it.net ldap_version = 3 base = dc=office,dc=on2it,dc=net scope=subtree auth_bind = yes auth_bind_userdn = "%u(a)office.on2it.net" pass_attrs = sAMAccountName=user user_attrs = sAMAccountName=user What happens in this case is best shown by a snippet of dovecot logging: Mar 5 09:57:36 <mail.err> ponyboy dovecot: auth: Error: ldap(js,127.0.0.1,<z1dLNtjzJwB/AAAB>): ldap_search(base=dc=office,dc=on2it,dc=net filter=(&(objectClass=posixAccount)(uid=js))) failed: Operations error Mar 5 09:57:36 <mail.err> ponyboy dovecot: imap: Error: Disconnected from auth server, aborting (client-pid=7247 client-id=1) Mar 5 09:57:36 <mail.crit> ponyboy dovecot: auth: Fatal: master: service(auth): child 7245 killed with signal 11 (core not dumped - set service auth { drop_priv_before_exec=yes }) Mar 5 09:57:36 <mail.info> ponyboy dovecot: imap-login: Internal login failure (pid=7247 id=1) (internal failure, 1 successful auths): user=<js>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=7248, secured, session=<z1dLNtjzJwB/AAAB> I find this intriguing -- "1 successful auths", so says imap-login, with auth dying horribly. I smell a rat. Something's wrong here...

[Dovecot] Send and Bounced mail not appearing, depending on mail client
by Dominique 05 Mar '14

05 Mar '14

Hi, I just installed Dovecot2 on Ubuntu 12.04 server with postfix and postfixadmin. I am using virtual users and virutal domains. When using Thunderbird, Roundcubemail,iOS mail application on an iPad2 or Kmail n Android, all mail sent and bounce shows up. However, when using vTigerCRM to send mails, nothing shows up - anywhere. I know the mail are being send - as per the mail.log and the various postfix log lines. But none of that is being captured by Dovecot... What am I missing? Thanks for any hints you can provide.

This does not test what you want, which is trying to authenticate the master user, not the regular user. From what I remember of your config, you have another passdb which holds the credentials of your master user: you need to check that file to make sure the master user's password (hash) matches what you think the master password ought to be.

[Dovecot] Hidden virtual folder
by Moritz Augsburger 04 Mar '14

04 Mar '14

Hi, I wanted to create a virtual folder containing all unread messages and the threads they belong to, and this config works really fine: > dovecot.conf: namespace { type = private prefix = virtual/ separator = / location = virtual:~/Maildir/virtual:INDEX=MEMORY list = children subscriptions = no } > virtual/All/dovecot-virtual: * -Trash -Trash/* -Junk -Junk/* -Drafts -Drafts/* -virtual -virtual/* all > virtual/New/dovecot-virtual: virtual/All inthread refs or unseen recent The only problem I got is that scanning all files for the virtual/All mailbox takes too long, and I would like to keep them cached (no INDEX=MEMORY), so I thought I'll just put virtual/All inside a second virtual namespace. As it's a bad idea to open the All directory manually, I could also hide the complete namespace to the user. So I added the following to my config: namespace { type = private prefix = virtual-all/ separator = / location = virtual:~/Maildir/virtual-all/ hidden = yes list = no subscriptions = no } But sadly it didn't work, a directory virtual-all/ pops up inside my client (thunderbird/icedove). Is hidden=yes/list=no unsupported for virtual locations, or is it me misconfiguring dovecot? If it should matter, it's version 2.2.9, or more specific debian 1:2.2.9-1~bpo70+1. Thanks Moritz

Hi, I did the upgrade frpom 1.2.x to 2.2.10 and had some warnings/errors on a very few accounts/mailboxes. All of them where permission related and solved. Dovecot rocks again. But on one mailbox I do get an error: Error: user rechnnugseingang-animationsinstitut: Initialization failed: Initializing mail storage from mail_location setting failed Error: Invalid user settings. Refer to server log for more information. There is a homedirectory and the permissions are set like on all other accounts. The username is quite long (35 characters) but an other one with 34 is working fine. And before the upgrade there was no error. Thnaks for any help or hint. Regards .

[Dovecot] Dovecot, AD and authenticated binds...
by Jeroen Scheerder 03 Mar '14

03 Mar '14

I posted earlier with reports of less than stellar success in using Active Directory for dovecot authentication. My approach is to using the two-step approach of - obtaining the user DN by a search using an authenticated bind (using a service account) - then binding as that DN, and returning the relevant user attributes This hasn't been succesful. Dovecot's authentication process does perform the (first) authenticated bind successfully, it does obtain the right DN, than just sits there doing nothing as far as I can tell, and after a long delay concludes authentication failure - shortly before deciding to perform the bind with the user-supplied credentials, successfully. Source inspection has not resulted in a glorious eureka yet. So I thought, why not handle it myself? And I wrote a little script, using the checkpassword interface. I've enclosed it. The script is based on <http://wiki2.dovecot.org/AuthDatabase/CheckPassword>, but somehow the userdb_uid and userdb_gid I've passed back in the "EXTRA" environment variable get lost along the way. It syslogs, and the syslogs show that the LDAP parts working as expected: Mar 3 14:49:09 <mail.info> ponyboy checkpassword: successful authenticated bind and DN(js) lookup Mar 3 14:49:09 <mail.info> ponyboy checkpassword: DN(js) is CN=Jeroen Scheerder,OU=Users,OU=Netherlands,OU=ON2IT,DC=office,DC=on2it,DC=net Mar 3 14:49:09 <mail.info> ponyboy checkpassword: js authenticated In dovecot's log, simultaneously, I see basically a successful login, except that the (user_)uid and (userdb_)gid work - unless I disable prefetch, and use a static userdb: Mar 03 14:49:04 auth: Debug: Loading modules from directory: /usr/local/lib/dovecot/auth Mar 03 14:49:04 auth: Debug: Read auth token secret from /var/run/dovecot/auth-token-secret.dat Mar 03 14:49:04 auth: Debug: auth client connected (pid=90856) Mar 03 14:49:09 auth: Debug: client in: AUTH 1 PLAIN service=imap secured session=+qFODbTzDgB/AAAB lip=127.0.0.1 rip=127.0.0.1 lport=143 rport=63246 resp=<hidden> Mar 03 14:49:09 auth: Debug: checkpassword(js,127.0.0.1,<+qFODbTzDgB/AAAB>): execute: /usr/local/etc/dovecot/checkpassword-on2it /usr/local/libexec/dovecot/checkpassword-reply Mar 03 14:49:09 auth: Debug: checkpassword(js,127.0.0.1,<+qFODbTzDgB/AAAB>): Received input: userdb_uid=143 userdb_gid=143 Mar 03 14:49:09 auth: Debug: checkpassword(js,127.0.0.1,<+qFODbTzDgB/AAAB>): exit_status=0 Mar 03 14:49:09 auth: Debug: client passdb out: OK 1 user=js Mar 03 14:49:09 auth: Debug: master in: REQUEST 4007395329 90856 1 29571963894e557ab643d2e51872ba55 session_pid=90899 request_auth_token Mar 03 14:49:09 auth: Debug: prefetch(js,127.0.0.1,<+qFODbTzDgB/AAAB>): success Mar 03 14:49:09 auth: Debug: master userdb out: USER 4007395329 js uid=143 gid=143 auth_token=e2d7c2463dd4c039010e904afb4ea45214cb7de5 Mar 03 14:49:09 imap-login: Info: Login: user=<js>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=90899, secured, session=<+qFODbTzDgB/AAAB> Mar 03 14:49:09 imap: Error: user js: Mail access for users with UID 143 not permitted (see first_valid_uid in config file, uid from userdb lookup).

[Dovecot] Tracking logins
by Alex 03 Mar '14

03 Mar '14

Hi, I'm using dovecot-2.1.17 on fc18 and wondered if there is some mechanism, perhaps a database, that can store the logins/logouts for each user? I realize there's something already logged to syslog, but I'd like more of a history. While lastlog is great for users that actually login, my dovecot users don't login, just check email via pop and imap. Any ideas greatly appreciated. Thanks, Alex
