Re: [Dovecot] Dovecot rejecting Vpopmail User 89

Enable auth_verbose and check the logs. But I'm pretty sure that means Dovecot can't change to the Maildir folder. I assume the user's folder is owned by vpopmail:vchkpw? Is the Maildir NFS mounted or local? Rick Quoting hobie(a)rumormillnews.com: > Thanks, Rick. :) Changed first/last uid/gid so all show 89 and restarted > Dovecot, no change.

[Dovecot] BUG - lmtp multiple recipients fail - setuid issue?
by Boris Lordis 24 Aug '11

24 Aug '11

Hello, I am not having much luck on this particular issue so I wanted to make sure that this is registered as a potential bug. The essence of the problem is that for a given message addressed to multiple users, lmtp writes the message correctly to the first addressed user only, then subsequent user writes fail as the lmtp process doesn't run with the proper permissions and tries to link files from different users as part of its message writing. Below you can see that lmtp (running with steve's id, who was the first listed recipient) is trying to link a file in jerry's inbox meeting with failure: Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, steve): Error: link(/spool/mail/j/jerry/mail/INBOX/u.20423, /spool/mail/s/steve/mail/INBOX/.temp.1311791081.P12412Q2M989550.testmailserver.) failed: Permission denied Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, steve): +1IXBeVXME58MAAARoVNxQ: msgid <201107271824.p6RIOPa5020900 at backup.>: save failed to INBOX: Internal error occurred.

[Dovecot] Attachments not removed from single store
by Karsten Becker 24 Aug '11

24 Aug '11

Hi. Well, I've the next problem. I turned on the new attachment de-duplication stuff in the configuration. If I send an attchment between two accounts on my test system, the attment gets saved ion the configured mail_attachment_dir. But... if I delete it from the senders Send folder and the receivers Inbox (and of course empty Trash afterwards in both cases), the hashes and the attachment are not deleted in mail_attachment_dir (as I would expect). Is this a bug, or have I misunderstood the concept of storing attachments?

[Dovecot] Cannot delete subfolder in public folder
by Karsten Becker 24 Aug '11

24 Aug '11

Hi there, I have the problem that I'm unable to delete a subfolder (again) I created within a public folder. I've already read about configuring Thunderbird to delete immediately - which I did. But it still doesn't work. I delete -> the folder is gone -> I get a TB error message saying "The folder doesn't exist" -> after restarting TB the folders appear again. Maybe someone has a hint. My tip is that I may have a wrong understanding of the ACL mechanism... :-( Regards from Berlin/Germany Karsten ------------------------ Log: > Aug 24 00:01:37 mail01 dovecot: imap(karsten.becker(a)company.eu): Debug: acl vfile: file /etc/dovecot/global-acls//.DEFAULT not found > Aug 24 00:01:37 mail01 dovecot: imap(karsten.becker(a)company.eu): Debug: acl vfile: file /srv/vmail/user-mailboxes/company.eu/karsten.becker/mailboxes/dovecot-acl not found > Aug 24 00:01:37 mail01 dovecot: imap(karsten.becker(a)company.eu): Debug: acl vfile: file /etc/dovecot/global-acls/Folders/test01/aaa not found > Aug 24 00:01:37 mail01 dovecot: imap(karsten.becker(a)company.eu): Debug: acl vfile: reading file /srv/vmail/public_folders/test01/aaa/dovecot-acl Here's the filesystem structure in /srv/vmail: > root@mail01.compdmz.local:/srv/vmail# ls -l public_folders/test01/ > total 20 > drwxr-xr-x 5 vmail vmail 4096 2011-08-23 23:50 aaa > drwxr-xr-x 2 vmail vmail 4096 2011-08-23 21:45 cur > -rw-r--r-- 1 vmail vmail 25 2011-08-23 22:19 dovecot-acl > drwxr-xr-x 2 vmail vmail 4096 2011-08-23 21:45 new > drwxr-xr-x 2 vmail vmail 4096 2011-08-23 21:45 tmp > root@mail01.compdmz.local:/srv/vmail# Here's the content of dovecot-acl (there are another ones in subfolder aaa with the same content, inherited during creation): > authenticated lrwstipekx Here's my configuration of Dovecot: > # 2.0.13: /usr/local/dovecot-2.0.13/etc/dovecot/dovecot.conf > # OS: Linux 2.6.32-33-server x86_64 Ubuntu 10.04.3 LTS ext4 > doveconf: Warning: Dovecot was last started using /etc/dovecot/dovecot.conf, but this config is /usr/local/dovecot-2.0.13/etc/dovecot/dovecot.conf > auth_cache_negative_ttl = 0 > auth_cache_size = 10 M > auth_mechanisms = plain login > base_dir = /usr/local/dovecot/var/run/dovecot > dict { > acl = mysql:/etc/dovecot/dovecot-dict-shared-mailboxes-mysql.conf > expire = mysql:/etc/dovecot/dovecot-dict-expire-mysql.conf > quota = mysql:/etc/dovecot/dovecot-dict-quota-mysql.conf > } > log_timestamp = "%Y-%m-%d %H:%M:%S " > login_greeting = Company Institute > mail_attachment_dir = /srv/vmail/attachments > mail_attachment_hash = %{sha256} > mail_cache_min_mail_count = 2 > mail_debug = yes > mail_location = mdbox:/srv/vmail/user-mailboxes/%d/%n > mail_plugins = acl expire quota > mailbox_idle_check_interval = 1 mins > namespace { > inbox = yes > location = > prefix = > separator = / > subscriptions = yes > type = private > } > namespace { > list = children > location = mdbox:/srv/vmail/user-mailboxes/%%d/%%n > prefix = Users/%%d/%%n/ > separator = / > subscriptions = no > type = shared > } > namespace { > list = children > location = maildir:/srv/vmail/public_folders:INDEX=/srv/vmail/user-mailboxes/%d/%n/public_folders-seen:LAYOUT=fs > prefix = Folders/ > separator = / > subscriptions = no > type = public > } > passdb { > args = /etc/dovecot/dovecot-mysql.conf > driver = sql > } > plugin { > acl = vfile:/etc/dovecot/global-acls:cache_secs=300 > acl_shared_dict = proxy::acl > expire = Trash > expire2 = Trash/* > expire3 = Junk > expire4 = Junk/* > expire_dict = proxy::expire > quota = dict:User quota::proxy::quota > quota_rule = *:storage=10485760 > quota_rule2 = Trash:storage=+1048576 > quota_warning = storage=95%% quota-warning 95 %u > quota_warning2 = storage=80%% quota-warning 80 %u > } > postmaster_address = postmaster(a)company.eu > protocols = imap pop3 > service auth { > unix_listener /var/spool/postfix/private/auth_dovecot { > group = postfix > mode = 0660 > user = postfix > } > unix_listener auth-master { > mode = 0600 > user = vmail > } > user = root > } > service dict { > unix_listener dict { > mode = 0600 > user = vmail > } > } > service imap-login { > inet_listener imaps { > port = 993 > ssl = yes > } > process_min_avail = 2 > } > service imap { > vsz_limit = 512 M > } > service pop3-login { > inet_listener pop3s { > port = 995 > ssl = yes > } > } > service quota-warning { > executable = script /usr/local/bin/quota-warning.sh > user = vmail > } > ssl = required > ssl_cert = </etc/postfix/ssl/mail01.compdmz.local.crt > ssl_key = </etc/postfix/ssl/mail01.compdmz.local.key > userdb { > args = /etc/dovecot/dovecot-mysql.conf > driver = sql > } > verbose_proctitle = yes > protocol lda { > auth_socket_path = auth-master > postmaster_address = postmaster(a)company.eu > } > protocol imap { > imap_client_workarounds = delay-newmail > imap_max_line_length = 128 k > mail_plugins = acl expire quota imap_acl imap_quota > } > protocol pop3 { > pop3_client_workarounds = outlook-no-nuls oe-ns-eoh > }

[Dovecot] LDA and auth-userdb socket permissions
by a.smith＠ukgrid.net 24 Aug '11

24 Aug '11

Hi, just wanted to check this as the wiki seems to have contradictory information. With respect to running the LDA as multiple UIDs the wiki says: [QUOTE]If you're using more than one UID for users, you're going to have problems running dovecot-lda, as most MTAs won't let you run dovecot-lda as root[/QUOTE] But in the example for the config file the text reads: [QUOTE] service auth { unix_listener auth-userdb { mode = 0600 user = vmail # User running dovecot-lda #group = vmail # Or alternatively mode 0660 + dovecot-lda user in this group } } [/QUOTE] So it says you can stick the LDA user just in the (vmail or whatever) group and that is enough. So you aren't restricted to a single UID for access anymore... I tested this and the later did not work, that is if I put my LDA user in the group for the auth-userdb socket with permissions 0660 I got an error back from dovecot saying that the owner was incorrect. So, as it stands I guess the bit about setting group should be removed from the wiki? Secondly, why doesn't this currently work? Why is the owner all important? thanks Andy.

[Dovecot] dovecot and tcpwrappers
by Kees Lemmens 23 Aug '11

23 Aug '11

Hi, I used dovecot 1.x for quite a while and it worked fine. However, I used it through inetd and used hosts.allow/deny to restrict access to only certain groups of systems. Since yesterday I have dovecot 2.0.13. But in version 2.0.13 it seems that starting using inetd doesn't work anymore : I only get a strange error message if I try to connect using telnet : telnet localhost imap doveconf: Fatal: execvp(imap-login) failed: No such file or directory I tried a lot of things but couldn't get it going over inetd so I decided to start it directly using an init script, also because you say in the wiki this is (now) the preferred method. That indeed works fine, but I realised today that dovecot is now completely ignoring all my hosts.allow/deny settings and so is worldwide accessible ! Is dovecot indeed ignoring hosts.allow/deny ? And if so, how can I have the same amount of protection as I previously had with dovecot 1.x over inetd ? BTW: I tried to post on the mailinglist but it seems I can't access them it the moment, altough I did subscribe and login. Is there anything wrong ? Thanks for your reply ! -- With best regards, Kees Lemmens. ----------------------------------------------------------------------- Delft Institute of Applied Mathematics (DIAM), Faculty Electrical Engineering, Mathematics and Computer Science, Delft University of Technology, Delft, The Netherlands,

[Dovecot] zlib plugin doesn't read concatenated .gz mailbox
by Dmitry Nezhevenko 23 Aug '11

23 Aug '11

Hi, I've observed that dovecot doesn't displays all mails from compressed via gzip mailbox (mbox). At the same time "mutt -f mailbox.gz" displays it correctly with all messages. I'm using archivemail to archive old mails. Internally it creates new "gzip" archive with "expired" messages and then concatenates it with archive. The easiest way to reproduce it without archivemail is to create two mailboxes, gzip them independently and then concatenate to one gzip archive. mutt, gunzip and other tools understands such archives. Also I've shared such mbox: http://dion.org.ua/uploads/2011/07/dovecot_test_gzip.gz It should contains ~20 messages. dovecot will "see" only two first. PS. % sudo dovecot --version 2.0.13 -- WBR, Dmitry

[Dovecot] dovecot's documentation dearth
by Postmaster 23 Aug '11

23 Aug '11

Hello. The first thing for me to say is thanks! I've been using dovecot since test 61 and it has basically performed flawlessly for me from day number 1. Dovecot makes me look like a genius sysadmin, especially compared to my colleagues struggling with exchange. So thanks, gracias, obrigado!! I'm working on a configuration for 2.0 and I'm finding the documentation somewhat difficult. I think it would be very helpful to me to have encountered a single page that detailed all available configuration sections. I don't know how to find out what the sections are, when to use them or what specifically they control. So far I've encountered... passdb plugin service protocol userdb local_name (and I think there is another one of these for ips) The service section itself would benefit from a single page detailing all of the possible types of service sections available. The next problem I've had is discovering that several parts of dovecot have no documentation at all even though they are standalone executables run by root. config, log, and ssl_params all run as root but there is also anvil and they look to me like they could support listening on a port if inet_interfaces is defined. You can say, "Relax fella, trust me. These programs are all part of dovecot and are run only if they're needed." Then I'll say, "Yes but I'm the administrator. I need to know how the parts fit together to know if the system's broken." Then you say, "Well that makes sense, but the things you're talking about aren't really configured. They are mostly internal to dovecot, they just happen to be broken out into external programs. You may as well be asking for documentation on a specific function in a library. If that's what you want, you can read through the source code." Well I guess that would be one solution. The bottom line is that it gives me an uncomfortableness to not be able to control or explain the operation of the software I'm supposedly administering. Take the program named log (which should be named dovecot-log or something less generic), it is launched even though I've specified syslog in the configuration. Logging is not interrupted when the process is killed. So, why is it running? What is it doing? Why does it need root? How do I control it? I think these are all good questions for an administrator to ask. That's my feedback for what it's worth, but mostly, thanks again for dovecot!

[Dovecot] dovecot deadlock with procmail
by kunal verma 23 Aug '11

23 Aug '11

I m using dovecot 1.0.7. I m having problems in mail delivery to my mail server locally. When a user sends a mail few mails are in mail Q for longer period of time. The local delivery agent(*procmail*) is trying to deliver the mail at regular interval but it is unable to deliver. But as soon as I *restart* *dovecot* the mails in the Q are delivered immediately. I suspect it is because of locking of *mbox* file of users by dovecot. How to overcome this problem as mails are some mails are taking hours to be delivered?? please let me know the solution.

[Dovecot] Large Mailbox Slow
by Matt 23 Aug '11

23 Aug '11

Doubt if there is any answer to this but will ask anyway. Have a few pop3 accounts with thousands of messages. Its slow when checking email naturally. Are there any tweaks to speed it up? I imagine there is an exchange of the message and header list which is the slow down. Too bad the list could not be compressed with gzip or something first. I think http has an option similar to that. Just asking.

[Dovecot] Dovecot Postfix and ssl_require_client_cert
by mezzo 23 Aug '11

23 Aug '11

Hi, I have a working mail system with postfix 2.7 and dovecot 1.2.15. I use secure connections for imap and smtp. When I try to use client certificate authorisation I have some problems. As soon as I enable the dovecot feature ssl_require_client_cert I have to present a valid certificate to receive or send email. Receiving emails works fine, but I can not send emails any more. The only way I could get this to work was to disable smtpd_sasl_auth_enable so postfix did not tries to get authorisation from dovecot. This way I can not have sasl authorisation for localnet and client certificate authorisation from extern. The reson seams to be that postfix does not sent the valid-client-cert along with the other parameter that are needed to satisfy the auth-process of dovecot. I found a few threads from 2008 where this problem is discussed but without a final solution. Is there a way to enable ssl_require_client_cert in dovecot and have smtpd_sasl_auth_enable=yes in postfix? Better would be a way to tell dovecot only to use ssl_require_client_cert during the imap autorisation. I did not get it to work. I miss something?

[Dovecot] Update indexes with dovecot 1.1
by Angel L. Mateo 23 Aug '11

23 Aug '11

Hello, I have a farm of dovecot 1.1 servers (debian lenny). Mailboxes are in Maildir format. Is there any way to manually update indexes? Does it worth? I mean... Our problem is that mail is delivered via dovecot lda, but, because we have a farm of servers, we don't guarantee that mail is delivered through the same server that the user is using for his imap connection, so the imap server could have this index unupdated. So I want to force an update (or at least nearly updated) in order to have the index updated in all servers at the time the user get to work. -- Angel L.

Using current Apple mail 4.5 as client to Dovecot 2.0.13 I see lots of these messages in the log file for one machine and account. Near as I can tell, the client still works (it's mine), but, the messages concern me. Is there some known issue with Apple mail, or, if not, how to capture the information needed to debug?

[Dovecot] Duplicate Email with Dovecot Sieve
by Holden Hao 22 Aug '11

22 Aug '11

I am trying to use Dovecot Sieve after upgrading Dovecot from 1.0.15 to 1.2.17. I used the same config file from the old version but I added some entries to make sieve work. In my initial tests, sieve works and is able to do the actions that I set it to do. However, I get 2 copies of incoming emails. The inbox would always preserve a copy even if the sieve filter is set to transfer emails to another folder or redirect it to another address. The logs do not seem to report any issues. I don't know what causes the problem and I would appreciate some pointers.

[Dovecot] Dovecot 1.2.16 and Thunderbird 5 - pop3 mails not getting deleted
by Ian Evans 22 Aug '11

22 Aug '11

I run a Dovecot 1.2.16 pop3 server and have just started using the Thunderbird 5 email client. Thunderbird is set to leave the messages on the server unless they are over 91 days old. However, I'm not seeing it delete any of the older messages. I'll run a debug run of Thunderbird when I get back home, but I'm just wondering if there's any gotcha's I should be aware of with Thunderbird and Dovecot in a pop3 environment. The Thunderbird folks are wondering if it's the server not the client. Thanks.

Upgrading to Dovecot2 would allow you to solve this in various ways: - use "doveadm force-resync" - user director to bind to a particular server You could put the indices on a shared filesystem. If neither an update nor shared indices are feasible, maybe you can enable the master user feature, and run a script that logs in as each user and do an IMAP operation that will force a resync of the INBOX indices. For example, # On IMAP server with a localhost interface for u in $users; do echo "1 login $u*master masterpw\n2 SELECT INBOX\n3 logout" | \ nc 127.0.0.1 143 done Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] Sharing all mailboxes and userdb LDAP attrs
by Felipe Scarel 19 Aug '11

19 Aug '11

Hello all, I'm setting up a Dovecot environment here, version 1.2.15 on Debian 6.0.2 "squeeze". This is actually a complete revamp of the previous setup we have in-place here, built from the ground up with updated versions of all involved software. The operators have told me that they use some scripts hacked up by a previous sysadmin to give a single "admin" account full access to all user mail. That is, if any user runs into problems, they: 1. Call in; 2. The operator logs in as the admin user; 3. Operator performs maintenance duties on user email. I've been researching the possibility of using Dovecot shared namespaces to perform that very same task in a better fashion in this new server. So far, I've been able to globally share users' INBOXes and view them from a single admin account (through user= entries on global acl's). My ultimate goal, however, is to have access to all user mailboxes with any user that's a member of a particular group, adding all operators to that group as needed. - - - - - First question, then, is this one: how can I give global access to all user mailboxes? I've read that it's possible to give access to all subfolders of a particular folder throught the use of a .DEFAUL acl. That didn't seem to work with the uppermost directory, however. Here's what I tried: root@mail:/etc/dovecot# dovecot -a | grep acl: acl: vfile:/etc/dovecot/acl:cache_secs=300 root@mail:/etc/dovecot# cat acl/.DEFAULT owner lrwstipekxa user=admin lrwstipekxa Renaming .DEFAULT to INBOX does achieve the intended goal, but only for the INBOX folder evidently. - - - - - Second question is somewhat simpler. So far I've been using a single admin user, but I'd like to switch to using an admin group in the future. I've read that the best way to do that would be to use the user_attrs entry in my dovecot-ldap.conf file, while using a userdb ldap. The groups should be strings separated by commas in the appropriate attribute, from what I understand. Is there any readily-available or recommended schema I can use to fill up that attribute? I'm using the default ones (plus samba.schema) but I've seen mostly space to fit GID's, not group names. Thanks in advance, fbscarel PS: Here's my dovecot -a output, should it be needed. - - - - - root@mailaluno:~# dovecot -a # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-amd64 x86_64 Debian

[Dovecot] mdbox and doveadm purge

Hi, has anyone figured out how to use the dovecot-antispam plugin with sa-learn? I need to pass the username (user(a)domain.tld) to sa-learn and --ham or --spam depending on the move. I was thinking of using the CRM14 option and replace the command and arguments but cannot find anything about the ability to pass the username. Any pointers would be welcome. N.

[Dovecot] May Dovecot help in users education
by Alexandre Chapellon 18 Aug '11

18 Aug '11

Hello, I was wondering if dovecot could help me in my project to smoothly make all my users switch to TLS encrypted POP / IMAP sessions and forget about cleartext. My first idea was to setup dovecot as a POP/IMAP proxy for my mailhosts and ask dovecot to display a warning message or slowdown non TLS sessions. Is there any way to achieve this with dovecot? Does anybody have another idea smoothly force used to switch to TLS? Regards. -- <http://www.horoa.net>

[Dovecot] invalid credential using openldap
by Daminto Lie 17 Aug '11

Hi, What I have been trying to achieve is to be able to authenticate users through openLDAP while using Postfix, Dovecot as IMAP server and squirrelmail. I keep getting the following error messages when trying to login to squirrelmail 2011-08-17 12:27:59 auth(default): Info: client in: AUTH 1 PLAIN service=imap secured lip=127.0.0.1 rip=127.0.0.1 lport=143 rport=57794 resp=AGFkbWluAGFwbXg2c3Bu 2011-08-17 12:27:59 auth(default): Info: ldap(myuser,127.0.0.1): invalid credentials (given password: xxx) 2011-08-17 12:28:00 auth(default): Info: new auth connection: pid=1921 2011-08-17 12:28:01 auth(default): Info: client out: FAIL 1 user=myuser 2011-08-17 12:28:06 imap-login: Info: Aborted login (auth failed, 1 attempts): user=<myuser>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured This seems to be trivial but I just could not figure out what else went wrong.

The following is what I have in /etc/dovecot/dovecot-slapd.conf hosts = localhost dn = cn=myadmin,dc=mycompany,dc=com dnpass = secrets auth_bind = yes auth_bind_userdn = cn=%u,ou=people,dc=mycompany,dc=com ldap_version = 3 base = ou=people, dc=pbj, dc=com, dc=au scope = subtree user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid user_filter = (&(objectClass=posixAccount)(uid=%u)) pass_attrs = uid=user,userPassword=password pass_filter = (&(objectClass=posixAccount)(uid=%u)) Thank you in advance

[Dovecot] Slackware Dovecot recompile with SSL/TLS question
by CopalFreak 16 Aug '11

16 Aug '11

I am having some problems and was told to ask in this list to try and get some help. When asking elsewhere, I was told that I was too verbose, so I'll try to be as brief as possible, while still including all the pertinent info. Slackware 13.1.0 Dovecot 2.0.8 Postfix 2.4.3 MySQL (virtual users) Spamassassin 3.3.1 ClamAV 0.97.1 (without Amavis) Have wild-card SSL certs and CA from GoDaddy ##"postconf -a" >> cyrus >> dovecot I compiled Dovecot without SASL support and need to re-compile it WITH SASL support, but I don't want to mess up my existing configuration. (I have it the way I want it as far as where it's installed, where the conf files are located, UID, GID settings, etc.) Dovecot 2.0.13 is out and I would prefer to use the newer version assuming it doesn't have any problems that would prevent me from using it. Is there a way to re-compile (or upgrade) so that it doesn't change any of my existing settings? I would like to be able to bring it down, do upgrade, maybe copy some config files over the defaults etc, and bring it all back up within a few minutes instead of a week of tweaking and fixing stuff. Is there a way to do something like this : stop dovecot backup all dovecot conf files ./configure CPPFLAGS=-I/path/to/openssl LDFLAGS=-L/path/to/openssl --config_dir /etc/dovecot/dovecot.conf (or something like that..not sure what it actually is) make sudo make install edit conf files to point to SSL certs start dovecot IN CASE anything goes wrong, copy old config files back and restart dovecot to make it go back the way it was (only it's using the new 2.0.13 version) any suggestions and/or tips on how-to do this would be greatly appreciated. Thanks!

Hi, I'm using dovecot 1.2.15 with ISPConfig and Roundcube with sieve plugin. To avoid conflicts between ISPConfig and Roundcube during script writing I would use include in the ISPconfig template to use the roundcube script To simplify this task I'm wondering if there is a way to have a "star include", like include :personal "*.sieve"; Thank you Andrea

[Dovecot] mbox originally needed 0 bytes, now needs maxint bytes
by Mike Brown 16 Aug '11

16 Aug '11

I'm running dovecot 1.2.16 from the ports collection on FreeBSD 8.1-STABLE, amd64. I've long been getting the following in my logs, seemingly at random (so, only sometimes), when I access or move mail into mboxes: Aug 16 00:43:58 myhost dovecot: IMAP(mike): mbox /home/mike/mail/feedback: seq=88 uid=91 uid_broken=0 originally needed 0 bytes, now needs 18446744073709551615 bytes Whatever I'm trying to do always succeeds, but apparently dovecot is confused about something. That number (2^64-1) suggests it has to do with the amd64 architecture. Did a compile option get overlooked? Let me know if there's anything I need to do to get rid of these warnings. Thanks, Mike

[Dovecot] imap-login aborted login
by Daminto Lie 16 Aug '11

16 Aug '11

Hi, I have been trying to set up Apache2, Postfix, Dovecot, openLDAP and squirrelmail on my Ubuntu Server 10.04 machine. The idea is to make use of the LDAP to authenticate users to login to squirrelmail to send/receive emails. I have been using the link - https://help.ubuntu.com/community/Postfix/DovecotLDAP, as a guide to get it all set up. I have checked the status for postfix and dovecot, and they both are up and running by using telnet. I have even installed openldapadmin to check and see if I've got the ldap working. I could login to openldapadmin and saw myself there with uid=msmith. I have also installed squirrelmail as my webmail. After all that installed, I went to localhost/squirrelmail on the firefox browser. It would not log me in. Later I found in the /var/log/dovecot-deliver.log file, I saw the following messages dovecot: Info: Dovecot v1.2.9 starting up (core dumps disabled) imap-login: Info: Aborted login (auth failed, 1 attempts): user=<msmith>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured imap-login: Info: Aborted login (auth failed, 1 attempts): user=<msmith(a)mycompany.com.au>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured imap-login: Info: Aborted login (auth failed, 1 attempts): user=<mike.smith(a)mycompany.com.au>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured I tried to login with three different usernames but none worked as shown above in the log file. I wonder if it is to do with method=PLAIN and secured. Any help would be greatly appreciated. Thank you

[Dovecot] Last login script
by Munroe Sollog 15 Aug '11

15 Aug '11

I am trying to implement a last login script, however I seem to be having lots of issues. We started with sqlite but we were having locking issues, so we moved to postgresql which seems to have alleviated database specific issues, but now people are complaining about randomly not being able to log in. I don't see any real errors in the logs (dovecot or postgresql) to explain their complaints though, all I am really getting is "Connection closed" here is the log line of a failed attempt (with debug output): http://pastebin.com/5RFgVa8V and here is what we are running as the 'mail executable': http://pastebin.com/L0ibyqSQ Any help would be greatly appreciated, thanks.

[Dovecot] LMTP over STDIN/STDOUT (non root user)
by Andrzej Adam Filip 15 Aug '11

15 Aug '11

Is it possible to get LMTP session over STDIN/STDOUT (for non root user)? I have configured dovecot to allow "server less" access to my mailbox using IMAP over STDIN/STDOUT. I would like to complete the setup by making fetchmail deliver fetched messages via LMTP over STDIN/STDOUT. -- [pl>en: Andrew] Andrzej Adam Filip : anfi(a)onet.eu There is only one way to kill capitalism -- by taxes, taxes, and more taxes. -- Karl Marx

[Dovecot] [PATCH] net_connect_*(): Wait for fd to complete connect(2) when fd is non-blocking
by SATOH Fumiyasu 15 Aug '11

15 Aug '11

Hi, Dovecot ignores EINPROGRESS on connect(2) for non-blocking fd. This is wrong. After that, read(2) to fd (or write(2) to fd) fails with ENOTCONN if the connection of fd is not completed. The attached patch fixes this problem. -- -- Name: SATOH Fumiyasu (fumiyas @ osstech co jp) -- Business Home: http://www.OSSTech.co.jp/ -- Personal Home: http://www.SFO.jp/blog/

[Dovecot] Blocking auth services
by Peter Mogensen 15 Aug '11

15 Aug '11

Hi, I'm writing an passdb/userdb plugin to authenticate against an external daemon listening on a UNIX socket. The connection to the daemon is 1 request at a time and thus blocking (unlike passdb-ldap), but the daemon is preforking, so it can handle more connections at a time. I read from the Wiki: http://wiki2.dovecot.org/Design/AuthProcess * "The authentication may begin new authentication requests even before the existing ones are finished. ", and * "If the passdb uses connections to external services, it's preferred that they use non-blocking connections. Dovecot does this whenever possible (PostgreSQL and LDAP for example). If it's not possible, set blocking = TRUE. " ... which tells me to set the module as blocking and let more auth worker processes do the work - creating 1 daemon process for each auth worker process, I guess. But I also have the option, to let the passdb/userdb plugin maintain a pools of used/idle connections to the daemon and just pick a idle connection and moving it to the used pool on each auth_request. Which would save me the auth worker processes. Is there a preferred dovecot way? /Peter

[Dovecot] Parallel auth
by Bernhard Schmidt 15 Aug '11

15 Aug '11

Hello, we run a Dovecot 2.0.13 instance purely as SASL backend for Postfix, authenticating against a local passwd-file and our central LDAP database. # dovecot -n # 2.0.13: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32.36-0.5-default x86_64 SUSE Linux Enterprise Server 11 # (x86_64) auth_mechanisms = plain login auth_verbose = yes passdb { args = /etc/dovecot/dovecot-passwd driver = passwd-file } passdb { args = /etc/dovecot/dovecot-ldap-simauth.conf.ext driver = ldap } protocols = none service auth { unix_listener /var/spool/postfix-postout/private/auth { group = postfix mode = 0660 user = postfix } } ssl = no There is only a single user in the passwd-file for monitoring. We monitor authentication delays for both this local user and one user from LDAP. Due to a firmware bug, our six-figures NAS causes extremely high LDAP delays (in the range of 20-60 seconds, instead of the usual 50ms) once an hour. The weird thing is, I also see these delays in the graph for the local user. Which got me thinking * are authentication requests handled serially by dovecot/auth? * any way to solve this situation for the local user (not to be blocked by the delayed LDAP query)? * any way to solve this situation for LDAP users? We could possibly do some loadbalancing if the auth-daemon opened several LDAP connections Thanks, Bernhard

[Dovecot] $IP not getting set?

15 Aug '11

Using dovecot 2.0.13. I went to implement relay-ctrl per directions on the Wiki, and failed. After running it down, as best as I can determine, the problem is that the $IP variable is not getting set (and thus not re-set in the script wrapper). I plunked a "set >> debug" into the script, and the only env var's that are set are as listed below (slightly sanitized for public display). Anyone have any ideas? I have tried both the Wiki-way, and this way: http://dovecot.org/list/dovecot/2009-December/045139.html with identical results.

[Dovecot] shared mailboxes
by Vasil Mikhalenya 15 Aug '11

15 Aug '11

Hi all, I've read all documentation that I could find, but I can not understand 2 simple things 1. How to create a public mailbox - with per user seen flag. In my configuration this flag is shared 2. How to share one user mailbox with other users and set up acl. In Cyrus it was very easy( cyradm sam mailbox user1 lrs or sam mailbox user2 all ). What way there is to do this in dovecot. It was no problem with shared mailboxes in cyrus, but I need maildir support.
