[Dovecot] 1.0rc3 problem w/ Thunderbird 1.5.0.5 on Mac OS X
by Herr Nagengast 02 Aug '06

02 Aug '06

Howdy, I'm very excited about the new dovecot release because I've been having problems with a hang on saving messages to my sent-mail box over imap+ssl. I installed 1.0rc3 over my 1.0rc2 install on FreeBSD 5.3 in the same manner as all the other upgrades I've done. After checking my email, tbird became nonresponsive and I saw this repeating in my logs ad infinitum: Aug 2 10:17:10 grin dovecot: imap-login: Login: user=<todd>, method=plain, rip=192.168.1.125, lip=64.142.74.74, TLS Aug 2 10:17:10 grin dovecot: IMAP(todd): Effective uid=1001, gid=1001 Aug 2 10:17:10 grin dovecot: IMAP(todd): mbox: data=/home/todd/mail:INBOX=/var/mail/todd Aug 2 10:17:10 grin dovecot: IMAP(todd): mbox: root=/home/todd/mail, index=/home/todd/mail, inbox=/var/mail/todd Aug 2 10:17:10 grin dovecot: IMAP(todd): file index-mail.c: line 785: unreached Aug 2 10:17:10 grin dovecot: child 87476 (imap) killed with signal 6 Aug 2 10:17:10 grin dovecot: IMAP(todd): Effective uid=1001, gid=1001 Aug 2 10:17:10 grin dovecot: IMAP(todd): mbox: data=/home/todd/mail:INBOX=/var/mail/todd Aug 2 10:17:10 grin dovecot: IMAP(todd): mbox: root=/home/todd/mail, index=/home/todd/mail, inbox=/var/mail/todd Aug 2 10:17:10 grin dovecot: imap-login: Login: user=<todd>, method=plain, rip=192.168.1.125, lip=64.142.74.74, TLS Aug 2 10:17:11 grin dovecot: IMAP(todd): file index-mail.c: line 785: unreached Aug 2 10:17:11 grin dovecot: child 87478 (imap) killed with signal 6 Restarting my mail client had no effect on the problem, nor did restarting the server.

[Dovecot] Thunderbird and mbox
by Thomas Hummel 02 Aug '06

02 Aug '06

Hello all, Does anyone has a workaround for the fact that thunderbird, when used in IMAP with the mbox format, doesn't let the user delete mailboxes : As a matter of fact, only messages can be deleted, since TB tries to move what it wants to delete into the "Trash" box, which would of course mean a sub-box of an mbox mailbox ? -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] Question re: .mailboxlist to .subscriptions migration
by S JList 02 Aug '06

02 Aug '06

Hello. I'm in the final stages of installing Dovecot on a new server, and then will be migrating user mailboxes from an older server that was using UW-IMAP. I realize that I will have to rename the ".mailboxlist" file to ".subscriptions". But, I have a question about the "mail/" directory part that appears for most mailboxes in each users .mailboxlist file: since I'm configuring my Dovecot to use multiple hidden namespaces (one of which will include "mail/"), do I still have to remove the "mail/" directory portion of each entry in the subscription file by hand, or will the namespace settings take care of "ignoring" that part of each listed mailbox? I hope this question makes sense. TIA for any help. SJ sjlist(a)heidelberg.edu

[Dovecot] What's the latest on RC2 and Thunderbird
by Ian Thurlbeck 02 Aug '06

Hi Just been reading a few threads on the sent-mail hang problem on Thunderbird (TB) and dovecot 1.0RC2 I'm getting reports from WinXP SP2 users running TB 1.0.7, server CentOS 4.2 and dovecot 1.0RC2 There were some suggestions: * Set max cached connections to 1 in TB - but this can result in access problems with blocking processes * Upgrading to TB 1.5.0.5 - not guaranteed to work * Downgrading to 1.0beta8 - works? Does anyone have a definitive answer to this problem ?

[Dovecot] Inconsistent handling of CRLF in APPEND
by Richard Birkett 02 Aug '06

02 Aug '06

One of the recent 1.0 commits relating to CRLF handling (maybe 2006-06-24) has changed the behaviour of APPEND when using mbox files with ordinary plain text emails. When a client stores a new message using an APPEND command (eg. saving a draft or copy of a sent message), it uses CRLF consistently as a line-ending throughout the literal data block over the wire - both for the header and the body. At least, this is what both Pine and Thunderbird do, so I suspect it's correct according to the IMAP specs, though perhaps there are grey areas around 8bit messages with no transfer-encoding. When Dovecot stores the message in the mbox file, it *used* to convert all the CRLFs to LF. Since the change, it is still converting the CRLFs in the header, but is leaving them intact in the body. The result is a weird hybrid format within the file. FETCH seems to undo the damage - at least, it sends back data with CRLF in both the header and the body - so provided the only access to the mail-store is through Dovecot, the clients are none the wiser. Dovecot also seems to handle existing messages (stored with LF only) OK too, and doesn't seem to be re-encoding them on update (eg. status changes). However, direct local access to the hybrid new messages will only work if the client is lenient about line endings: Pine seems OK, but others might not be, expecting an mbox file to be consistently "Unix" format. Is this a regression introduced while trying to fix the attachment corruption problem, or just a brand new bug?! Hopefully there is a way of reverting this change without reintroducing the attachment problem. Richard

[Dovecot] Quota with dict backend - sql does not get registered
by David Jonas 02 Aug '06

02 Aug '06

Hello everyone, I've been working with the quota plugin, attempting to use the dict backend. It seems the sql dict class is not getting loaded. I dropped a couple lines in dict_class_lookup(dict.c) and it seems the only class that gets loaded is "proxy". Any idea how to get the sql driver to load in the quota/dict module? My authentication goes through the sql module and is working perfectly, so I know that the module and db are talking in general. I've scoured the documentation and dug through the code but I can't seem to discover the solution. There is "Dynamic SQL drivers" in the compiling from source section: http://wiki.dovecot.org/CompilingSource#line-158 I compiled the driver_mysql.so, copied it to lib/dovecot/, symlinked it into auth/, imap/, pop3/ and lda/, then tried-- but it still only showed "proxy" as being loaded. After that I added it to the mail_plugins list, mail_plugins = driver_mysql quota but it didn't like that and spat out some linking errors: Edlopen(/usr/local/dovecot-1.0.rc2/lib/dovecot/imap/driver_mysql.so) failed: /usr/local/dovecot-1.0.rc2/lib/dovecot/imap/driver_mysql.so: undefined symbol: sql_not_connected_result So, where do I go from here? Any insights would be appreciated and I'll keep digging. Regards, David

I'm looking forward to figuring out how to allow users to have access to (old) email in mbox format, an have all new mailboxes go to maildirs. . . But I digress. When we switched, no one complained of performance issues -- except myself. mail.app would seem to stall on caching a message, then report that it was reconnecting, and move a bit further, then stall. . . What apparently was happening was the dovecot was polling for /dev/urandom, over and over again, waiting for some random bits, and Mail.app would timeout and reconnect. Turning off SSL made it MUCH faster. Of course, that's not a solution. So, I hunted the mailing lists, and ran across some notes about dovecot using /dev/urandom a little too enthusiastically. I haven't had a chance to grub through the code (hard to do with a 2-year old that won't sleep until midnight on many a nights!), and this post is somewhat premature, but I'm curious if turning off SSL removes the problem. Of course, switching to a Linux server will (sort of) negate the problem, in that apparently Linux is a little faster at finding random bits (I guess, I've never looked into it). My server is Solaris 9. My client is Mail.app from 10.3.9. As I grub through the code, I'll try and identify cryptographically significant randomness from non-cryptographically significant randomness. Sean

[Dovecot] Public Namespace & ACL & Virtual Users
by Fintec 01 Aug '06

01 Aug '06

Background: I am wanting to create shared folders (public namespace) with access control lists on the sub directories. Our implementation of dovecot (v1.0b7) uses many virtual users and domains and 1 actual user (vmail), all using maildir. So far I have successfully created the public namespace (Public_Folders) which every user can access but I'm having difficulty restricting access using ACls. When trying to implement the dovecot ACL plug-in I followed the wiki instructions and created a "dovecot-acl" file within Public_Folders containing: owner lrwstiekxa user=user1(a)domain.com lrwstiek However this doesn't appear to do anything. All users can still access Public_Folders so I have a couple of questions that hopefully someone can help me with... 1) Is it possible to use the dovecot's ACL plug-in on a Public name space? 2) Is it possible to create dovecot-acl files with virtual usernames, i.e. user1(a)domain.com or does it have to be actual users, i.e. vmail? 3) Is it possible to restrict access within the namespace definition, i.e. set up another public namespace restricted to manager(a)domain.com? 4) Is ACL accepts & denies logged somewhere other than /var/log/maillog (my default)? 4) Is anyone successfully set-up an environment with a public namespace and ACLs? Any help would be greatly appreciated. Gavin

[Dovecot] Dovecot and Sun's Directory Server
by Brian Hechinger 31 Jul '06

31 Jul '06

I've got Sun's Directory Server 5.2 installed here, and I would like to have dovecot use it for virtual users. I have the following questions: a) How do I get dovecot to link to DS's libraries? Am I better off just building OpenLDAP client libraries and linking dovecot with them instead? b) how about password-hash {CRYPT} in the OpenLDAP config file? Do I need to do anything to make DS5.2 do that for me the right way? c) Schema. Can I use the OpenLDAP schema? Does DS5.2 have the correct schema for my needs? Which exact schema does dovecot use? Maybe I can check and see what's in there and what needs to be added/extended. I think that's it for now. ;) -brian

[Dovecot] Dovecot and SSL certificates
by M.-A. Lemburg 31 Jul '06

31 Jul '06

Hello, we're running RC2 and seeing a problem with the way SSL certs are handled by Dovecot. We've set ssl_verify_client_cert=yes and ssl_require_valid_client_cert=no. Using this setup we get (rather interesting) log entries like these: Jul 31 11:21:23 dev dovecot: imap-login: Invalid certificate: <user cert> Jul 31 11:21:23 dev dovecot: imap-login: Invalid certificate: <CA cert> Jul 31 11:21:23 dev dovecot: imap-login: Valid certificate: <CA cert> Jul 31 11:21:23 dev dovecot: imap-login: Valid certificate: <user cert> Jul 31 11:21:23 dev dovecot: imap-login: Login: user=... When setting ssl_require_valid_client_cert=yes, logins always fail with: Jul 31 11:57:54 dev dovecot: auth(default): PLAIN(?,...): Client didn't present valid SSL certificate Are we doing something wrong, or is dovecot mixing up something while checking the certificates. Note that the certificates are all valid and have not expired. The <user cert> is signed by the <CA cert> and we set ssl_ca_file to the CA certificate PEM file. Ideally, we'd like to only accept login requests from users which have a valid certificate signed by our CA. Even better would be an approach such as the one taken by Postfix where you have to provide a list of valid MD5 hash sums for the users you'd like to accept.

[Dovecot] Problem copying Dovecot 0.99 - Dovecot 1.0rc2 IMAP messages
by Stephan Holl 27 Jul '06

27 Jul '06

Dear List, I have a problem copying lots of IMAP-messages from one server running Dovecot 0.99 over to my new server running dovecot 1.0rc2.

Hello, using the cmusieve plugin with the postfix + dovecot-lda. Filtering works, and dovecot logs, but for sieve filtering I see no message in the syslog about performed actions. How do I set this? thanks

[Dovecot] dovecot-smtp connection?
by J Moore 26 Jul '06

26 Jul '06

This may be a dumb question, but I'll ask because... :) I've got dovecot installed and running successfully on OpenBSD 3.9 (this *really* was an easy setup, my hat's off to the developer(s)). And the other employees can now use MS Access to read their mail (they didn't like mutt and pine via SSH - go figger'). So my final challenge is to get things configured so that they can also *send* mail through the same host that dovecot is installed on. I *think* this has to be configured in sendmail, but I'm hoping that someone can confirm that before I start reading. Thanks, Jay

[Dovecot] IMAP issues?
by J Moore 25 Jul '06

25 Jul '06

I've probably done something dumb, but a quick search on Google, etc has turned up nothing I recognized as useful. I just installed dovecot on an OpenBSD 3.9 box. It is working fine with secure POP3 (after changing the config file to "mbox_write_locks = fcntl"). I also selected secure IMAP as a protocol, but it is proving to be more resistant to working. I am trying to connect to dovecot using Outlook as a client (sigh). Outlook's error messages are to the effect that it is unable to connect to the server. Looking in /var/log/maillog indicates that a connection was not even attempted! I've configured the client to use SSL (port 993), and tried diddling with some of the other parameters to no avail. I also tried to connect using the Thunderbird IMAP client with similar results. I've obviously missed something in my dovecot setup, but just don't see it... can anyone offer a clue? Thnx, Jay

[Dovecot] Multiple attempts to get mail delivered
by Gerard Seibert 24 Jul '06

24 Jul '06

FreeBSD 6.1 STABLE I am using a basic MBOX mail setup. I have noticed that when the MBOX size starts to grow, say 35-30M or more, Dovecot will not always deliver the mail via POP on the first attempt. In fact, in some cases it takes four or five attempts before it will actually deliver the mail. Is there some setting that I should be changing? There does not appear to be any error written to the log file. Ciao! -- Gerard Seibert gerard(a)seibercom.net Take diplomacy out of a war and the thing would fall flat in a week. Will Rogers

[Dovecot] [PATCH] Substitution of dots to ", dc=" in variable expansions
by Antonio Kanouras 24 Jul '06

24 Jul '06

Hi list, my ldap directory uses DNs like this: uid=solist,ou=People,dc=solistland,dc=net,ou=Virtuals but I only could use something like uid=solist,ou=People,dc=solistland.net,ou=Virtuals with dovecot, which obviously isn't what the dcObject object class was meant to present. I've written a small function for var-expand.c which introduces a new modifier for string variable expansions, %D (arbitrarily chosen), which substitutes dots to ",dc=". You might want to include that in dovecot's code base, after bringing it up to dovecot standards of course. :-) Example of use: base = ou=People,dc=%Dd,ou=Virtuals Warning: I'm a beginner in C and could only understand so much of dovecot's code, so this patch is a hack at best. That said, I tested it with more than 10k logins and can say it works for me. :-D Cheers, Antonio

[Dovecot] Maildir++ quota - how to handle a full mailbox
by Joseph W. Breu 24 Jul '06

24 Jul '06

Hello all, We are using Horde/IMP and we are having problems deleting messages from accounts where the user is very close to going over quota. My test environment includes: Horde 3 IMP 4.1.2 dovecot 1.0rc2 postfix maildrop I created a user and set the quota at 13MB. I then sent a 10MB file to the user - which was received. However, when I attempt to move the message from the INBOX to Trash, I get a Quota Exceeded error. Is this more of an IMP error than a dovecot quirk? Is the message size credited back to the quota after the message has been removed from the INBOX? Is there any way to change the order that the qouta usage is applied? -- Thanks, --------------------------------------------------------- Joseph W.

[Dovecot] MySQL table for use with dict et quota
by mikael 24 Jul '06

24 Jul '06

In your "http://wiki.dovecot.org/Quota/Dict" documentation, the table to create is : create table quota ( path varchar(255) not null primary key, username varchar(255) not null, current integer ); "path" field is the primary key. But when i see the SELECT queries, "path" is always used ('quota/storage') and username too. I don't understand... If "path" is the primary key, it must be unique in quota table ? Perhaps the table would be like this : create table quota ( path varchar(255) not null, username varchar(255) not null, current integer, primary key (path, username) ); No ? I start to have a headache... :D 2 days with dovecot quota, and no fully working results :'( Please, help me :) -- Mikaël

[Dovecot] POP does not seem to be working
by Gerard 23 Jul '06

23 Jul '06

OK, I am brand new to this so please bear with me. I have an FreeBSD 6.1 STABLE system. Postfix is installed with qpopper. The mailboxes are standard mbox format. I just installed Dovecot. At some point I want to update to a mdir format, etc., but quite frankly I do not know how to go about that. In any case, I shut down qpopper and started Dovecot. I modified the Dovecot.conf file SSL settings (turned them off) since I do not have the files it needs built yet. Anyway, when using a mail client on another PC on my network, although it makes a connection, no mail is ever downloaded. Ther is mail in the folders however. Obviously I am doing something really wrong, but I am not sure what. I would sure appreciate any assistance available. The only information I have is in the 'log' file which shows the a pop3-login, the user name, method=PLAIN, and two numeric addresses. Thanks! -- Gerard Seibert gerard(a)seibercom.net

[Dovecot] help with authentication - cpanel
by allan hardy 22 Jul '06

22 Jul '06

I am trying to install dovecot as a second pop3 service in my RH9 system. It is a Cpanel based system using Courier for primary IP By primary I mean all the other domains use courier on xxx.xxx.xxx.21 port 110 I have a domain with special pop3 needs that is dedicated to xxx.xxx.xxx.22 port 110 The two mail systems are installed, I can tell via telenet that dovecot is listening and responding on the desired IP and port Cpanel is the tool being used by all domains to create mail accounts and hence setting the 'policy' for the mailboxes, userdb and passdb information. I am trying to make dovecot use those files and can't get past authentication. What I guess I don't know is the encryption type being used by Cpanel Any help appreciated.!!!! What Cpanel appears to do for authentication is use a passwd and shadow file for each domain, placed as follows: /home/accountname/etc/domainname/passwd holds the list of mail accounts names /home/accountname/etc/domain/shadow holds the passwords This is the message log from a telnet session on local machine: dovecot: Jul 22 13:45:27 Info: auth(default): client in: AUTH 1 PLAIN service=POP3 secured lip=xxx.xxx.179.22 rip=xxx.xxx.179.22 resp=AGFsbGFuAHRlc3Q= dovecot: Jul 22 13:45:27 Info: auth(default): shadow(allan,xxx.xxx.179.22): password mismatch dovecot: Jul 22 13:45:29 Info: auth(default): client out: FAIL 1 user=allan dovecot: Jul 22 13:45:36 Info: pop3-login: Aborted login: user=<allan>, method=PLAIN, rip=xxx.xxx.179.22, lip=xxx.xxx.179.22, secured ~ This was in the shadow file: ---Shadow file entry allan:$1$V0lG6T6P$eNQoX3J3N5RJNxT5yH8gz1::::::: These are my relevant (At least I think they are relevant) dovecot.conf settings: disable_plaintext_auth = no ssl_disable = yes auth default { mechanisms = plain login anonymous passdb shadow { /home/xxxxxx/etc/xxxxx.com/shadow } userdb passwd-file { # Path for passwd-file args = /home/xxxxxxx/etc/xxxxx.com/passwd } --PAM is commented out As a side note, I tried to see if I could tell from the courier setup how it was authenticating. The courier/etc/pop3d file was set POP3AUTH="" And there was a note "To advertise the SASL capability, per RFC 2449, uncomment the POP3AUTH variable" So it this may indicate sasl is being used, what ever that means

[Dovecot] Dovecot and quotas
by mikael 22 Jul '06

22 Jul '06

Hello, I have succesfully installed dovecot version 1.0.rc2 on my Debian Sarge. I have configured quotas (just for tests) like this : == dovecot.conf == ... auth default { mechanisms = plain passdb pam { } userdb passwd { } } protocol imap { mail_plugins = quota imap_quota } plugin { # quota = 10 Mb quota = dirsize:storage=10240 } ... ================== Quotas works without problem : 10Mb for all users... But i would like quotas per user and kept thi default value of 10Mb... How to override this default value ? How to do peruser-quota with "passwd" userdb (or "passwd-file") ? Really thanks for your help, -- Mikaël,

[Dovecot] cmusieve plugin
by Stuart Sears 21 Jul '06

21 Jul '06

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi guys I have been doing a lot of searching, but maybe I am being dim (not unheard of!). I have dovecot-1.0rc2 built and running on Fedora Core 5. The wiki page (dated yesterday) states that I need the cmusieve plugin to use sieve scripts with the dovecot lda. Is this a new development? They seem to work quite happily on my soon-to-be retired 1.0-beta7 debian box without an extra plugin. secondly, if it is now necessary, where do I get this plugin from? (this may be the dim part) I have a cvs checkout of the dovecot sources, but I see nothing obviously connected to cmusieve anywhere in the source tree If this is in a different module, then can someone let me know the name of it, so that I can check it out of CVS as well?

[Dovecot] Migrating to dovecot
by Johann Spies 21 Jul '06

21 Jul '06

I do not have much experience in setting up imap servers - only that I have tried several and experienced the same problem with all of them. I suppose that is because I do not really know the in's and out's of an imap server. What I want to do is to setup an IMAP server on my PC with full access to all the emails already there in a maildir structure. I have the following setup: fetchmail -> procmail -> maildir exim for outgoing mail. When I install an imap server, I loose access to my present emails in ~/Mail and most imap-servers (dovecot included) seems to create a new structure within ~/Mail. ~/Maildir is a symlink to ~/Mail. Now my questions: 1. How do I set up dovecot to serve the present maildir to the user? 2. Related to 1: How do I migrate my emails to the new imap-maildir structure without losing any? 3. How would my present procmail-setup change? At the moment I have entries like the following: MAILDIR=$HOME/Mail # you'd better make sure it exists DEFAULT=$MAILDIR/Ander/new # completely optional :0: * X-Spam-Flag: YES saspam/new :0: * ^List-Id: <users.spamassassin.apache.org> spamassassin/new ...

[Dovecot] Soft limit quota

I'm using dovecot on our new mail server and it is pretty good.

[Dovecot] Patch suggestion
by Renaud Allard 20 Jul '06

20 Jul '06

Hi, Would it be possible to make a change in the configure file to search for gssapi.h in <kerberosV/gssapi.h> if it fails to find it in <gssapi/gssapi.h>? That would allow to compile dovecot with gssapi easily on OpenBSD without patching it.

[Dovecot] making Dovecot match Courier POP3 UID's
by Jeff Tucker 20 Jul '06

20 Jul '06

Hi, guys. I've read the information in the Wiki about making dovecot's UID's match Courier's UID's in the POP3 server, so that a UIDL command on either server will return the same UID's for the same group of messages. However, what I've read doesn't match what I'm seeing in Courier. Courier appears to keep the UID numbers for messages that it uses for the POP3 server separate from the UID numbers for the IMAP server. Courier has a file: courierpop3dsizelist which has a line for every message, like: 1129610881.6075832619.blade4:2,S 2361 1478:1065670602 1129727025.1168007000.blade1:2,S 14718 1479:1065670602 1130005953.3295720403.blade5:2,S 1554 1481:1065670602 1130108068.0849623942.blade5:2,S 8246 1482:1065670602 The first column is the maildir filename, the last column is the UID that the POP3 server uses and the UID validity. Both are used to create the UID number returned by UIDL. The IMAP server uses a completely different UID number that's stored in courierimapuiddb. So, it seems to me that dovecot can't ever match Courier's UID numbers for the POP3 server unless it reads and interprets this courierpop3dsizelist file. My Courier-IMAP installation is Courier-IMAP 4.0.6. Any ideas? This is a real hassle because it means I can't switch the POP3 server from Courier to Dovecot or, if I do, lots of my users will download every message again which is just unacceptable. Thanks Jeff

[Dovecot] proxy performance
by Vincent Fox 19 Jul '06

19 Jul '06

Can anyone speak to experience using Dovecot proxy to frontend for multiple back-end servers in a "large" environment? We have 50,000+ mailboxes spread across 10 POP/IMAP servers. We'd like to be able to put in a front-end setup on our load-balancer of 4 dual-CPU Sun systems. I am a bit concerned about performance issues although from what I have read the proxy can be set not to fork, which improves performance a lot. Still concerned about whether SSL loading will be an issue. We'd like to use LDAP to look up the reference to which mail-store a user is on. I see that the Wiki refers to SQL. The mailing list indicates passwd-file also works. Not clear about LDAP.

[Dovecot] /var/spool/mail directory size and subdirectories
by David Lee 19 Jul '06

19 Jul '06

(Complete newbie to dovecot. I hope what follows isn't something I've missed in some FAQ somewhere...) On a traditional UNIX filesystem with UW-IMAP several years ago, we encountered major performance problems when "/var/spool/mail/" got big (we would currently be ~20,000 entries). This was due to the inefficiency of the UNIX filesystem when creating and deleting the lockfiles (etc.) in a directory of that size. We worked around that (all those years ago) with a local source-code mod to UW-IMAP ("c-client") to use subdirectories "/var/spool/mail/00/" to "/var/spool/mail/99/" based on a trivially simply "uid mod 100" algorithm. (Our uids are random; our usernames are not.) Thus we had 100 subdirs each of about 200 entires. Efficiency and performance vastly improved, and we've been running like that ever since. Now we are considering migrating to dovecot... Does dovecot do file creation/deletion in this (or similar shared) directory? (And so would it be liable to the same inefficiency problems?) Is there some means in the "dovecot.conf" file to specify an INBOX pattern as "/var/spool/mail/%ZZZ%/%u" where "%ZZZ%" could be algorithmically specified as (say) "user-uid mod 100"? -- : David Lee I.T.

[Dovecot] strange dropping of Word.doc-attachements - sendmail dovecot RHEL4
by Götz Reinicke 19 Jul '06

19 Jul '06

Hi, we have a strange problem: two of our users informed me, that they aren't able to send word-.doc-files anymore while othe attachements work fine. The e-mail gets deliverd, but the attachement is dropped. This happens using the latest thunderbird 1.5.x and mac os x. The e-mail is also not saved in the send-drawer. If the users send the same e-mail to the same recepient using an other mailclient, there is no problem. Other users (like me) using the same systemsettings and software versions don't have the problem. The server is RHEL 4 (2.6.9-kernel), sendmail 8.13.1 and dovecot 0.99. We use Mailscanner and spamassassin too, but as only the two users do have the problem I'm looking for some help to track this problem down. Any ideas??

[Dovecot] Masking INBOX.INBOX

I then "SUBSCRIBE" in 4 to "INBOX" and dovecot translates that to subscribing to "INBOX.INBOX". Not a huge deal, but it does cause Thunderbird to act weirdly (although Thunderbird allows me to UNSUBSCRIBE to "INBOX" and still get new mail), but I'm not sure what the effect will be on other clients.

[Dovecot] Getting maildir++ quotas working
by Bill Boebel 18 Jul '06

18 Jul '06

Can somebody post details for how to get maildir++ quotas working in the latest CVS? I have tried but can't get the CAPABILITY string to show "QUOTA"; and the GETQUOTAROOT command is recognized, but returns nothing... 2 GETQUOTAROOT INBOX * QUOTAROOT "INBOX" "" * QUOTA "" () 2 OK Getquotaroot completed. These are the settings I have... am I missing something? protocol imap { mail_plugins = imap_quota quota mail_plugin_dir = /usr/lib/dovecot/imap } plugin { quota = maildir imap_quota = maildir } Here are some more details: Dovecot is creating the maildirsize file in my maidir, and it seems to show correct storage used calculations, but the first line which should contain my storage limits is blank. So I suspect that I am not returning a valid quota value from the user database. I am returning what my old Courier-IMAP wants to see "1073741824S,4000C"... if the format for Dovecot is different, what should the format be? So there are two problems that I am trying to resolve, but I'm not sure how to go about fixing it. Any help would be greatly appreciated: (1) Dovecot isn't announcing QUOTA support in the capability string. (2) Dovecot isn't getting a valid quota limit, which I assume is breaking the GETQUOTAROOT command. Thanks, Bill

Messages delivered by the MTA generally have a name like 1152736772.H956194P17632.mail.llorien.org:2,RS There is nothing in the SMTP server logs that could suggest these empty mails are delivered with SMTP and only dovecot version has changed. So I guess this is dovecot related. My IMAP client is thunderbird on Linux, but I have also seen the problem with sylpheed on OpenBSD. Any help or hint appreciated.

[Dovecot] Postfix Virtual Users and Directory Permissions
by Michael Starks 18 Jul '06

18 Jul '06

I have followed the instruction here: http://www.postfix.org/VIRTUAL_README.html#virtual_mailbox There are five virtual domains configured and each directory containing each domain is owned by one UID/UID with permissions of 700. I can send mail to each domain and it is stored in the appropriate Maildir under the correct directory. The system is OpenBSD 3.8 STABLE. So far, so good. Now comes Dovecot. What I would like to do is to have one set of credentials for 4 of the domains, and another for the remaining. I would also like to *not* use a database backend for authentication at this time and would prefer to stick with standard UNIX /etc/passwd and /etc/shadow. Considering the directories are all owned by one user, does Dovecot need to be configured to use the same user as auth_userdb = static? That would make sense. What I'm not clear on is how Dovecot would know which domains are associated with which user, and does the user need permissions to those directories or is that handled by impersonation? Thanks in advance.

[Dovecot] pop3 auth problem solved!
by Bruce Lane 16 Jul '06

16 Jul '06

Fellow techies, OK... This is going to go down as one of those "D'Oh!" moments in the world of computers. Boy, do I feel dumb... In short: I found the problem. One miserable little line in 'dovecot.conf' called 'auth_default_realm =.' I had this set to 'bluefeathertech.com,' thinking it was necessary to do so. I was wrong, at least for my environment, and the stupid clues were right in front of me in the logfile all the time! For the benefit of others who may run into this: Setting a domain name in this entry causes that domain name to be automatically appended to usernames when they log in. No wonder nothing ever matched in /etc/passwd! My deepest thanks to Frank Cusack for giving me the idea. Something he said in his post, in response to my initial one, got me thinking about things getting appended to the user name, and the rest is history. pop3 and pop3s both work just fine now, thanks. ;-) Keep the peace(es). -=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner & Head Hardware Heavy, Blue Feather Technologies -- http://www.bluefeathertech.com kyrrin (at) bluefeathertech do/t c=o=m "If Salvador Dali had owned a computer, would it have been equipped with surreal ports?"

[Dovecot] pop3 authentication problems: Still got 'em...
by Bruce Lane 16 Jul '06

16 Jul '06

Fellow users, This is just a heads-up to let the list know that I'm still unable to get ANY sort of pop3 or pop3s authentication to work with Dovecot. Just as a sanity check, I set up an entirely separate system, running FreeBSD 6.1 production, postfix 2.3, and Dovecot 1.0rc2, as a testbed. I got the exact same problem that I had with the NetBSD 3.0 production server, specifically that Dovecot refuses to authenticate a user with either basic pop3 or pop3s. The way I see it, I may as well try to get basic pop3 working first. If it doesn't, pop3s will never work. This first quote is taken from the mail client (Pegasus) trying to establish a regular, unencrypted pop3 session. -=-=-=-=-=-=- [*] Connection established to 192.168.42.80 >> 0058 +OK AVG POP3 Proxy Server 7.1.368/7.1.394 [268.10.1/389] << 0013 USER kyrrin >> 0005 +OK << 0016 PASS XXXXXXXXX >> 0029 -ERR Authentication failed. -=-=-=-=-=-=-=- As you can see, the user ID of 'kyrrin' is getting passed as just that, and Dovecot at least seems to recognize it. I say this as a prefix to the next log clip, which will be the corresponding entry from /var/log/maillog, in which the user name is being presented (for whatever reason) in FQDN format. Note that pam was added just as an experiment. It failed too, despite the presence of a 'dovecot' file, containing the following, in /etc/pam.d -=-=-=-=-=-=-=- pioneer# cat /etc/pam.d/dovecot auth required pam_unix.so nullok account required pam_unix.so pioneer# -=-==-=-=-=-=- This would be the /var/log/maillog entry corresponding to the above-referenced Pegasus session. -=-=-=-=-=-=-=- Jul 16 11:24:38 pioneer dovecot: auth(default): client in: AUTH 1 PLAIN service=POP3 lip=192.168.42.80rip=192.168.42.40 resp=AGt5cnJpbgBocDIxZHZlbTc= Jul 16 11:24:38 pioneer dovecot: auth(default): pam(kyrrin(a)bluefeathertech.com,192.168.42.40): pam_authenticate() failed: authentication error Jul 16 11:24:38 pioneer dovecot: auth(default): cache(kyrrin(a)bluefeathertech.com,192.168.42.40): User unknown Jul 16 11:24:40 pioneer dovecot: auth(default): client out: FAIL 1 user=kyrrin(a)bluefeathertech.com Jul 16 11:24:49 pioneer dovecot: pop3-login: Aborted login: user=<kyrrin(a)bluefeathertech.com>, method=PLAIN, rip=192.168.42.40, lip=192.168.42.80 -=-=-=-=-=-=-=- This next bit is the auth default section of my dovecot.conf file.

[Dovecot] auth with kerberos
by Renaud Allard 16 Jul '06

16 Jul '06

Hello, I am running dovecot 1.0RC2 and I'd like to know if there is a way to make dovecot provide PLAIN, LOGIN, CRAM-MD5, NTLM authentications from a kerberos database. GSSAPI works great, but I currently have to have two password databases, one for GSSAPI and one for all the others. What I'd like is to have only one password database (namely kerberos). I know that cyrus-sasl (which most of you don't like I think ;)) can provide such authentications, but I haven't found the way to configure dovecot to do the same. Any input welcome.

Re: [Dovecot] Deliever in RC2 incorretly outputs "saved mail to INBOX"

Hi All, I've recently upgraded to RC2 (debian package) and now I get the following message in syslog all the time: Jul 14 15:51:04 server01 deliver(alex): saved mail to INBOX This seems to happen for every mail, despite some being filtered into different folders. It goes like this: Mail arrives from Ubuntu mailing list: Jul 14 15:53:49 server01 postfix/qmgr[19023]: D51A95C023: from=<ubuntu-users-bounces(a)lists.ubuntu.com>, size=4319, nrcpt=1 (queue active) I get this message: Jul 14 15:53:51 server01 deliver(alex): saved mail to INBOX Postfix sends to deliver: Jul 14 15:53:51 server01 postfix/local[29843]: D51A95C023: to=<alex(a)placet.co.uk>, relay=local, delay=29, status=sent (delivered to command: /usr/lib/dovecot/deliver) ...and a few seconds later it shows up in my Ubuntu-Users folder, exactly where my sieve rule sends it. Is this a bug? Alex -- This message has been scanned for viruses and dangerous content by the MailScanner at Placet.co.uk, and is believed to be clean.

[Dovecot] Backing up mail
by Davide Bolcioni 14 Jul '06

14 Jul '06

Greetings, in backing up mail stored according to default_mail_env = mbox:~/mail/:INBOX=/var/mail/%u is it safe *not* to backup the .imap subdirectory ? I am currently using dovecot-0.99.13-3.FC3. When restoring, I guess the safe option would be to zap the contents of .imap so that it gets rebuilt, correct ? Thank you for your consideration, Davide Bolcioni -- Paranoia is a survival asset.

[Dovecot] TLS Issues - Plain Text login?
by Timothy White 14 Jul '06

14 Jul '06

I'm trying to setup IMAP, so that it works via secure connections. I have it working fine over SSL, now I wish to get TLS to work. I have set imap and imaps to both listen on *, and have disable_plaintext_auth = yes, which according to the docs, Disable LOGIN command and all other plaintext authentications unless SSL/TLS is used (LOGINDISABLED capability). So the problem is now, that TLS doesn't work. Trying it with thunderbird, I get a message about login being disabled, and to check my settings and such. The port is correct (imap, not imaps), and I have it to always use TLS. I see the following in my logs Jul 14 16:35:46 mafeking dovecot: imap-login: Aborted login: rip=58.7.136.163, lip=203.30.47.34, TLS Any ideas? To me it appears to be using TLS, so why doesn't thunderbird work? Is it the LOGINDISABLED capa keyword? Is it dovecot telling Thunderbird the wrong capa when using TLS? It all works fine with SSL, and the port (in thunderbird) set to the imaps port. The logs show lines like below when using SSL. Jul 14 16:36:32 mafeking dovecot: imap-login: Login: user=<joeblogs>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Any ideas? Or should I just force SSL?

[Dovecot] dovecot 1.00 RC2 bugs
by Alexander Zagrebin 14 Jul '06

14 Jul '06

imho, dovecot 1.00 RC2 has two bugs at the maildir quota implementation 1. Incorrect calculation of used storage and count of messages When calculating, dovecot counts "." and ".." directory entries. So, if there are no subdirs and messages in maildir, maildirsize still shows 4 messages and some used storage. My workaround is --- src/plugins/quota/quota-maildir.c.orig Sun Jun 11 21:36:24 2006 +++ src/plugins/quota/quota-maildir.c Thu Jul 13 11:33:58 2006 ======================================================== @@ -82,6 +82,8 @@ len = str_len(path); while ((dp = readdir(dirp)) != NULL) { + if (!strcmp(dp->d_name, ".")) continue; + if (!strcmp(dp->d_name, "..")) continue; p = strstr(dp->d_name, ",S="); num = (uoff_t)-1; if (p != NULL) { ======================================================== This patch skips special directory entries. 2. Under some condition maildirsize contains invalid data Consider a such situation 1. User begins pop3 session 2. dovecot calls this sequence of procedures maildir_quota_transaction_begin -> maildirquota_refresh -> maildirsize_read While reading maildirsize's data, may be situation when mailbox size must be recalculated (maildirsize greater 5120, quotas was changed...). In this case dovecot closes maildirsize's file descriptor (root->fd) and assigns it "-1". After that code calls maildirsize_recalculate -> maildirsize_write So maildirsize is rewritten and contains valid data. BUT file descriptor (root->fd) still contains "-1" 3. User retrieves and deletes some messages, then quits. So maildirsize must be updated. 4. Code calls maildir_quota_transaction_commit, but root->fd equals "-1", so maildirsize_update doesn't calls and maildirsize contains incorrect (obsolete) data My workaround is ======================================================== --- src/plugins/quota/quota-maildir.c.orig Sun Jun 11 21:36:24 2006 +++ src/plugins/quota/quota-maildir.c Thu Jul 13 11:33:58 2006 @@ -246,11 +248,12 @@ return -1; } - if (file_dotlock_replace(&dotlock, 0) < 0) { + if (file_dotlock_replace(&dotlock, DOTLOCK_REPLACE_FLAG_DONT_CLOSE_FD) < 0) { mail_storage_set_critical(storage, "file_dotlock_replace(%s) failed: %m", path); return -1; } + root->fd = fd; return 0; } ======================================================== This patch preserves fd after writing recalculated maildirsize file, and when maildir_quota_transaction_commit is called, root->fd contains valid file descriptor. -- Alexander Zagrebin

[Dovecot] pop3s Authentication Issues, Continued
by Bruce Lane 14 Jul '06

14 Jul '06

Fellow Dovecot'ers. I tried something tonight that I should have done a while back: Turned on verbose logging in the authentication section. I'm still unable to get the mail client I'm experimenting with (Pegasus) to complete a pop3s connection, in that I still get an indication of a failed password. However, at least I'm a little closer to understanding the failure itself. Please note what came up in /var/log/maillog. Jul 13 22:41:25 featherweb dovecot: auth(default): client in: AUTH 1 PLAIN service=POP3 secured lip=192.168.42.130 rip=192.168.42.40 resp=AGt5cnJpbgBocDIxZHZlbTc= Jul 13 22:41:25 featherweb dovecot: auth(default): cache(kyrrin(a)bluefeathertech.com,192.168.42.40): User unknown Jul 13 22:41:26 featherweb dovecot: auth(default): client out: FAIL 1 user=kyrrin(a)bluefeathertech.com More specifically: Take a good hard look at the end of the second line.

Re: [Dovecot] Error: imap-login: Can't connect to auth server at default: Resource temporarily unavailable
by Matt Roman 13 Jul '06

It appears the problem is in this function: int net_connect_unix(const char *path) { struct sockaddr_un sa; int fd, ret; memset(&sa, 0, sizeof(sa)); sa.sun_family = AF_UNIX; if (strocpy(sa.sun_path, path, sizeof(sa.sun_path)) < 0) { /* too long path */ errno = EINVAL; return -1; } /* create the socket */ fd = socket(PF_UNIX, SOCK_STREAM, 0); if (fd == -1) { i_error("socket(%s) failed: %m", path); return -1; } net_set_nonblock(fd, TRUE); /* connect */ ret = connect(fd, (void *)&sa, sizeof(sa)); if (ret < 0 && errno != EINPROGRESS) { close_keep_errno(fd); return -1; } return fd; } This function is returning -1 and the server is crashing - Most likely because of a socket error. The error message from the socket is "Resource temporarily unavailable" If anybody knows why that would happen, I might be able figure out a solution. Thanks!

[Dovecot] maildir++ quota bug...
by Joseph W. Breu 13 Jul '06

13 Jul '06

Running RC2 with maildrop and MDA: dovecot writes a positive quota count, then the negative quota count on messages delivered with maildrop. For example, message #1 arrives via maildrop: 4488236 1 message is deleted via dovecot: 4488236 1 -4488236 -1 This does not happen when the user accesses the message, only when it is deleted. The user never gets credit for deleting the file and their quota continues to grow. I did not notice this behaviour until now, but I just tested with rc1 and it is present there as well.

[Dovecot] proxy load-testing
by Vincent Fox 13 Jul '06

13 Jul '06

I found the proxy performance page in the Wiki. It's interesting to see such good performance for the proxy! However, I was trying to duplicate the tests and am not clear how. Anyone know what a typical test setup would look like? I need to document/test that I can setup a proxy able to handle 100-200 sessions per second which the folks around here are skeptical of. I emailed Tomi directly but got a vacation reply. I tried a quick test of my own with rabid and results seem questionable. Probably I am not using the right options on the command-line. I used a single client to generate the load and while I specified 20,000 per minute when I checked the maillog on my IMAP server it was authentication more like 300 per minute. I get a number of "Re-auth failure" messages even with 3720 accounts. I think this is due to the randomness being literal sometimes you hit again the same account name while a first attempt of it is still connected. Also not sure how Tomi generated those statistics, from the logs, from the rabid output? Since rabid doesn't do POP-mark numbers or anything I guess you just ramp up the load until the proxy slows down and call that your performance number?

Hi Let me introduce myself, My name is Cecil, and i am a system architect by proferssion working currently on contracts with serveral companies in Ghana and Nigeria. I recently built a Corporate Mail Server for a Company using Postfix, Dovecot and Squirrelmail, running on Ubuntu. Thanks to the Dovecot community everything is working well. After a moment i noticed that i could make the users change their own passwords using squirrelmail, but unfortunatly for me after googling around the Internet and also visiting squirrelmail plugin page i could not find a change Dovecot password plugin for squirrelmail. I want to throw this challenge to the Dovecot community to start a project on developing a change Dovecot password plugin for squirrelmail if none exis t as at now. I am ready to voluntee towards the development of the plugin. I will like to know from others especially the list administrators if the project can take off on the mailling list with any problems. Thank You. Office Of The SYSTEMS ARCHITECT DISCOVERYTEL GH

Re: [Dovecot] Authentication by certificats (a bug or my misconfiguration)

Hi Alexander, > > Thanks for the quick reply; rearranging the certs didn't seem to do > much for the setup; I guess I'm getting one thing wrong, which was the > cause for my followup. How can I make dovecot only rely on cert and no > furhter authentication for giving access to the user, when making > dovecot lift the user ID from the client cert? Hmm, i don't think that's the reason for the "invalid certificate" error. Another question: are the clientcertificates and the servercertificate signed by the same CA? In case you want the ssl-verify error in the logfiles: in src/logincommon/ssl-proxy-openssl.c, line 607 change: i_info("Invalid certificate: %s", buf); to: i_info("Invalid certificate: %s: %s, X509_verify_cert_error_string(ctx->error) ,buf); should help, (tested on beta8) (don't forget to recompile, install, restart ;-)) success! -- groeten, HenkJan Wolthuis

Re: [Dovecot] Quota over 2GB supported?

Yes, we are enforcing a 5GB per user quota using Dovecot's maildir++ quota support. This works with both 32-bit kernels and 64-bit. I know courier took some patching to make work with 32-bit kernels, but Dovecot supports it out of the box. The only caveat is the quota is only enforceable within one namespace, so make sure your Inbox and folders all use the same namespace. Bill

[Dovecot] passwd authentication issues (ATTN: Petar)
by Bruce Lane 12 Jul '06

12 Jul '06

Hi, Petar, For whatever reason, I didn't see your most recent reply until I checked the web archives. To answer your questions... Is my dovecot running chrooted? Not that I know of. However, the option to (apparently) decide this is confusing at best. Here is what I have entered. # chroot login process to the login_dir. Only reason not to do this is if you # wish to run the whole Dovecot without roots. # http://wiki.dovecot.org/Rootless login_chroot = yes Now, my guts tell me that this WILL make it run chrooted. However, reading the material at this link... http://wiki.dovecot.org/Rootless ...says otherwise, and that setting this to 'no' would be making it run chrooted. For reference, this is the process line from ps -aux|grep dovecot root 3182 0.0 1.4 256 876 ? Ss Sun08PM 10:10.06 /usr/local/sbin/dovecot Also, something else just turned up in the process list that I'm not sure I understand. Specifically... root 1817 0.0 1.6 324 1056 ? S 8:53PM 0:00.19 dovecot-auth dovecot 2191 0.0 3.0 256 1940 ? S 8:53PM 0:00.97 imap-login root 3182 0.0 1.4 256 876 ? Ss Sun08PM 10:11.78 /usr/local/sbin/dovecot dovecot 6333 0.0 3.0 256 1940 ? S 8:53PM 0:00.93 imap-login dovecot 8133 0.0 3.0 256 1940 ? S 8:53PM 0:00.97 imap-login dovecot 8397 0.0 3.0 256 1940 ? S 8:53PM 0:00.96 imap-login dovecot 16144 0.0 3.0 256 1940 ? S 8:53PM 0:00.92 imap-login This has me deeply confused. I'm not running IMAP, I'm not interested in running IMAP, I don't want anything to do with IMAP. However, there's five processes for imap-login. What gives? On to your second question: Are /etc/pwd.db and /etc/spwd.db available? Yes, both are listed in the directory of /etc as follows. -rw-r--r-- 1 root wheel 40960 Jul 9 09:56 /etc/pwd.db -rw------- 1 root wheel 40960 Jul 9 09:56 /etc/spwd.db featherweb: {41} How "available" this makes them (I don't know what context you were asking in), I'm not sure. Just for giggles, I tried chaning the permissions on spwd.db so that it was world-readable. Doing so had no effect. I still get password failure errors when I try to authenticate a pop3s connection from the client program. One other question: Pegasus (the mail client) has two options for secure POP connections besides apop (which I've shelved for the moment): STLS and direct SSL connection. I've got it set to direct SSL at the moment. Does this sound right? Looking forward to the next set of replies. Thanks much. -=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner & Head Hardware Heavy, Blue Feather Technologies -- http://www.bluefeathertech.com kyrrin (at) bluefeathertech do/t c=o=m "If Salvador Dali had owned a computer, would it have been equipped with surreal ports?"

[Dovecot] Problems with deliver (LDA)
by Claus Alboege 12 Jul '06

12 Jul '06

Hi, I'm using Dovecot's (1.0.rc2) 'deliver' (no sieve) as LDA - calling it from a .qmail file. It seems that 'deliver' destroys "message/rfc822" attachments (forward as attachment). My .qmail file looks like this, and use qmail to deliver a copy directly to my Maildir, and 'deliver' to deliver a second copy of the same message to the same Maildir: % cat .qmail ./Maildir/ |preline /usr/libexec/dovecot/deliver After forwarding a message (as attachment) to my account, I get the following 2 files in my Maildir. Check the difference in size: % ls -l Maildir/new -rw------- 1 csa csa 2818 2006-07-06 09:29 1152170973.7420.silver -rw------- 1 csa csa 1372 2006-07-06 09:29 1152170973.P7422Q0M136220.silver Grepping for ^Content-* in the 2 mails show that a part is missing. % cd Maildir/new % grep ^Content * 1152170973.7420.silver:23:Content-Type: multipart/mixed; 1152170973.7420.silver:28:Content-Type: text/plain; charset = "iso-8859-1" 1152170973.7420.silver:29:Content-Transfer-Encoding: quoted-printable 1152170973.7420.silver:34:Content-Type: message/rfc822; name="Testing" 1152170973.7420.silver:35:Content-Transfer-Encoding: 7bit 1152170973.7420.silver:36:Content-Disposition: attachment; filename="Testing" 1152170973.7420.silver:64:Content-Transfer-Encoding: quoted-printable 1152170973.7420.silver:65:Content-Type: text/plain; charset="iso-8859-1" 1152170973.P7422Q0M136220.silver:24:Content-Type: multipart/mixed; 1152170973.P7422Q0M136220.silver:29:Content-Type: text/plain; charset = "iso-8859-1" 1152170973.P7422Q0M136220.silver:30:Content-Transfer-Encoding: quoted-printable 1152170973.P7422Q0M136220.silver:35:Content-Type: message/rfc822; name="Testing" 1152170973.P7422Q0M136220.silver:36:Content-Transfer-Encoding: 7bit 1152170973.P7422Q0M136220.silver:37:Content-Disposition: attachment; filename="Testing" (sorry for the long lines) The offset in linenumbers is caused the the From line added by 'deliver'.

[Dovecot] Shared folders not woking for me
by Nagy László 12 Jul '06

12 Jul '06

Hello, I'm new to dovecot, please forgive me my silly questions. :-) My OS is FreeBSD 6.1. I just installed dovecot 1.0.beta9. I have created a public namespace this way: namespace public { separator = / prefix = Public/ location = maildir:/var/mail/public } namespace private { separator = / prefix = location = maildir:/home/%u/Maildir inbox = yes } Then I created a new group and added a user to it: pw groupadd das pw usermod testuser -g das Then I created some files in /var/mail/public: drwxrwx--- 2 testuser das 512 Jul 11 19:22 Tasks drwx------ 2 testuser mail 512 Jul 11 19:20 cur drwxrwx--- 2 testuser das 512 Jul 11 19:24 dovecot-shared drwx------ 2 testuser mail 512 Jul 11 19:20 new drwx------ 2 testuser mail 512 Jul 11 19:20 tmp Then I restarted dovecot, and I tried to subscribe to 'Tasks', but my email client (Thunderbird 1.5) does not allow it. My other problem is about the "inbox = yes" setting. The private namespace does have an inbox, and it shows up in thunderbird. But it does not show my e-mails. I know that I have emails, I can read them with the 'mail' command. Please help me. Laszlo

Re: [Dovecot] Dovecot and MySQL auth - initial setup issues

If you setup is in a virtual mailbox setup then your query should look something like this: user_query = SELECT maildir, 500 AS uid, 500 AS gid FROM users WHERE id = '%u' Try that out, replacing the 500's with the appropriate uid and gid and let me know what you see then.

[Dovecot] Dovecot and MySQL auth - initial setup issues
by Andrew Hearn 11 Jul '06

11 Jul '06

Hello, I'm just setting up a new server and wanting to use MySQL for user authentication. Here is what I have: Fedora Core 5: 2.6.17-1.2145_FC5 Dovecot v1.0.rc2 (RPM install from atrpms.net) MySQL v5.0.22 SquirrelMail v 1.4.6-7.fc5 ...Running on a Dual XEON machine I've added the following to dovecot.conf: auth default { passdb sql { args = /etc/dovecot-mysql.conf } userdb sql { args = /etc/dovecot-mysql.conf } The rest of dovecot.conf is standard. /etc/dovecot-mysql.conf has: driver=mysql connect = host=127.0.0.1 port=3306 dbname=maildb user=root client_flags=0 password_query = SELECT password FROM users WHERE id = '%u' user_query = SELECT maildir FROM users WHERE id = '%u' (I've run the SQL queries within mysql and they give the right results) When I start Dovecot the log shows: dovecot: Jul 11 12:47:25 Info: Dovecot v1.0.rc2 starting up dovecot: Jul 11 12:47:27 Info: auth-worker(default): mysql: Connected to 127.0.0.1 (maildb) When I try to log in using SquirrelMail, it takes about 3 seconds, then I get dovecot: Jul 11 12:48:00 Info: imap-login: Aborted login: user=<andrew(a)mail-test.aaisp.net.uk>, method=PLAIN, rip=::ffff:127.0.0.1, lip=::ffff:127.0.0.1, secured ...So, no log of it trying MySQL... And SquirrelMail then says: Unknown user or password incorrect Any ideas of what I'm missing? Thanks! Andrew.

[Dovecot] Authentication error with corrections
by Bruce Lane 11 Jul '06

11 Jul '06

Hi, Curtis (and the group), I tried setting up Dovecot's auth default section as you described, with both authdb and userdb set to 'passwd.' It let the authenticated session start on the POP side, but I got consistent authentication failures on the client side that the passwords didn't match. I don't have any more time to mess with it this morning, but I will make it a point to try 'shadow' when I get in this evening. It's possible that NetBSD wants to work that way. Thanks for your help. -=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner & Head Hardware Heavy, Blue Feather Technologies -- http://www.bluefeathertech.com kyrrin (at) bluefeathertech do/t c=o=m "If Salvador Dali had owned a computer, would it have been equipped with surreal ports?"

[Dovecot] Any news with the MS OE "Headers only" problem?
by Sysadmin 11 Jul '06

11 Jul '06

Hello. About year ago I tested OE and dovecot imap and met this problem (http://wiki.dovecot.org/Clients#head-129bcbfc238b5c34362b8216db87c05e7a34af…) - Using "Headers only" synchronization is buggy and can cause "Message is no longer available on this server" error when opening a mail. I configured OE to sync All messages, and it worked, but then it's acts like pop3 and downloads all messages and the local computer mailboxes are still there. However is there any news according this issue? How to use dovecot imap with OE and "Headers only" option selected? -- Sysadmin

[Dovecot] 1.0 migration

The version of Dovecot I am currently using keeps different read pointers depending on if it's being accessed by POP or IMAP. I understand that in 1.0this is unified. If I upgrade the server in place, what will the status of my messages be? Will everything be marked unread? IMAP pointers become official? POP pointers become official?
