I deleted the dovecot.index.cache file and it still will not display any messages in my inbox when I have the setting to only display the most current 30 days worth of mail. Jeff Timo, Just FYI, the above problem is still not fixed with beta 3. Jeff

[Dovecot] v1.1 QUOTA and inbox quota
by Kristian Vlahovicek 21 Oct '07

21 Oct '07

My mail agent is postfix and by default it imposes the INBOX size of 50 meg. I would like my imap mail clients (I'm using Thunderbird) to "see" this and warn me when my inbox fills up. I tried doing it with the old quota system but wasn't successful. With the new quota rule system it looks like per-mailbox quotas are possible, however when I do this: quota = maildir quota_rule = INBOX:storage=50000 I get an error in the log: Sep 28 02:18:31 discworld dovecot: IMAP(kristian): open((null)) failed: Bad address Sep 28 02:18:31 discworld dovecot: IMAP(kristian): Internal quota calculation error Sep 28 02:20:04 discworld dovecot: IMAP(kristian): open((null)) failed: Bad address Sep 28 02:20:04 discworld dovecot: IMAP(kristian): open((null)) failed: Bad address is there any way to get the inbox quota to work properly? I guess many systems use postfix and have 50M inbox limit so it would really be helpful if this information is pushed somehow through imap to the client. thanks, K

Postfix, by defaults, don't do more than 100 concurrent deliveries with the same transport, local in my case. I raised up auth_worker_max_count to 128, to accomodate 100 potential concurrent deliveries plus some pop3/imaps clients. The problem appears with certain frequency. There is no other info in the log besides the error notification. FWIW: I have auth_debug enabled.

[Dovecot] Errata: dovecot + ldap + virtual mailbox: building mail location path
by Claudio Strizzolo 20 Oct '07

20 Oct '07

Hi all again, I've just realized that I did a bad cut&paste in my previous mail, then I rewrite my request. I apologize. I am trying to set up my dovecot configuration using LDAP and virtual mailboxes. I succeeded in authenticating the users correctly with LDAP, but have problems with referencing the correct mail location directory. I manage several domains. The mailboxes are stored under separate directories for each domain: /mail/vmail/domains/writers.com/William.Shakespeare/ /mail/vmail/domains/writers.com/Jack.London/ /mail/vmail/domains/painters.com/Pablo.Picasso/ /mail/vmail/domains/painters.com/Vincent.VanGogh/ Now, I supposed I could build the path by setting the common part of the paths as mail_location into dovecot.conf: mail_location = maildir:/mail/vmail/domains/%h passdb ldap { args = /etc/dovecot-ldap.conf } userdb ldap { args = /etc/dovecot-ldap.conf } userdb prefetch { } and getting the variable part ("domain/user", i.e. writers.com/Jack.London) from the userdb in dovecot-ldap.conf: auth_bind = yes auth_bind_userdn = mail=%u,vd=%d,o=hosting,dc=example,dc=com ldap_version = 3 base = o=hosting,dc=example,dc=com deref = never scope = subtree user_attrs = mail,,mailbox,mail,, user_filter = (&(objectClass=VirtualMailAccount)(accountActive=TRUE)(mail=%u)) pass_attrs = mail=user,userPassword=password,mailbox=userdb_home,mail=userdb_uid,mail =userdb_mail pass_filter = (&(objectClass=VirtualMailAccount)(accountActive=TRUE)(mail=%u)) default_pass_scheme = CRYPT In the LDAP database the fields are something like: mail = Jack.London(a)writers.com mailbox = writers.com/Jack.London uid = Jack.London However, the above does not work. Here is an extract from the log: Oct 16 15:57:07 mymail.example.com dovecot: auth(default): ldap(Jack.London@writers.com,::ffff:127.0.0.1): user search: base=o=hosting,dc=example,dc=com scope=subtree filter=(&(objectClass=VirtualMailAccount)(accountActive=TRUE)(mail=Jack.London(a)writers.com)) fields=mail,mailbox,mail Oct 16 15:57:07 mymail.example.com dovecot: IMAP(Jack.London(a)writers.com): Ambiguous mail location setting, don't know what to do with it: writers.com/Jack.London/ (try prefixing it with mbox: or maildir:) Oct 16 15:57:07 mymail.example.com dovecot: IMAP(Jack.London(a)writers.com): Failed to create storage with data: writers.com/Jack.London Any hints? BTW, I am trying to prefetch, as you see, but I am not sure that works too. Thanks in advance Claudio

Hi, Resending this. Does anyone have a clue? -------------- I downloaded the updated files and now I also upgraded to beta2 as you released late last night. Good work maintaining dovecot I have to say. :-) Unfortunately  I still can't search using thunderbird. I get no errors in the log now but thunderbird doesn't find any messages. I have tried updating the index (in thunderbird) but still no messages found. It worked prior to updating. What could the reason be? Best Regards - Jon ps. I also now tried searching in Squirrelmail aswell. Didn't work. ds.

[Dovecot] Incomplete Subject Line
by Bernhard Schmidt 20 Oct '07

20 Oct '07

Hi, since upgrading from 1.0.5 to latest 1.1-hg I get an incomplete subject line for mails autogenerated by one of our systems in the message list (Thunderbird and mutt). When I open the mail the subject line is intact. It appears that the system is using multiline subjects. Example Subject: =?ISO-8859-1?B?SG9zdG1hc3RlcjogMDAwMDEwNjM1OiBOYW1lc2U=?= =?ISO-8859-1?B?cnZlcjogTmV1dmVyZ2FiZSBvZGVyIMRuZGVydW5n?= is printed as Subject: Hostmaster: 000010635: Namese in the Message list and correctly decoded as Subject: Hostmaster: 000010635: Nameserver: Neuvergabe oder Änderung when viewing the message. Bug? Regards, Bernhard

[Dovecot] Namespace Question
by Jeff Grossman 20 Oct '07

20 Oct '07

I installed 1.1Beta2 over 1.0.5 last night. My 1.0.5 setup was running with no problems at all. Stupid me overwrote my dovecot.conf file with a vanilla one. I know I know, backup!!! I am pretty sure my old dovecot.conf file did not specify any namespaces, but I could be mistaken. My Thunderbird and Squirrelmail are working fine on the new 1.1Beta2 setup. But, my smartphone running Windows Mobile 5.0 does not see the inbox or my folders. Does anybody know what might be different between 1.0.5 and 1.1Beta2 in regards to pocket outlook? This is on a Gentoo system. Here is my dovecot-n output. apple dovecot # dovecot -n # 1.1.beta2: /etc/dovecot/dovecot.conf protocols: imap imaps pop3 pop3s listen: [::] ssl_cert_file: /etc/ssl/dovecot/server.pem ssl_key_file: /etc/ssl/dovecot/server.key ssl_cipher_list: ALL:!LOW:!SSLv2 disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login mail_location: maildir:%h/.maildir mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 auth default: passdb: driver: pam args: * userdb: driver: passwd Thanks, Jeff

[Dovecot] Migration Issues UW-POP3
by Albert E. Whale 20 Oct '07

20 Oct '07

I am migrating from UW's POP3 server (mbox), to Dovecote (mbox -> maildir). Anyway, I am concerned about the Logging details offered by Dovecot, as I manage several details from the logging information provided by UW's Syslog information. Here's a sample of the UW information: Oct 7 22:08:39 ns6 ipop3d[15432]: pop3 service init from 66.207.133.233 Oct 7 22:08:39 ns6 ipop3d[15432]: Auth user=aewhale host=ns.ABS-CompTech.com [66.207.133.233] nmsgs=0/0 Oct 7 22:08:39 ns6 ipop3d[15432]: Logout user=aewhale host=ns.ABS-CompTech.com [66.207.133.233] nmsgs=0 ndele=0 The first time I connected to the server to test the information, I got the following: Oct 7 20:22:17 ns6 dovecot: Dovecot v1.0.rc26 starting up Oct 7 20:22:37 ns6 dovecot: pop3-login: Login: user=<aewhale>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Oct 7 20:23:44 ns6 dovecot: POP3(aewhale): Disconnected: Logged out top=0/0, retr=0/0, del=0/800,size=1576887 None of the other connections reported information about the mailbox or the connections.

[Dovecot] potential maildir folder rename bug
by pod 20 Oct '07

20 Oct '07

Admittedly not a common situation but: MAIL=maildir:~/tmp/dovecot/Maildir ./src/imap/imap * PREAUTH [CAPABILITY IMAP4rev1 SASL-IR SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN NAMESPACE LOGIN-REFERRALS] Logged in as pod 01 LIST "" * * LIST (\HasNoChildren) "."

I was expecting to wind up with two folders "INBOX" and "a.b". Instead I got "INBOX" and "a.b.b". I think the problem is that ".a" gets renamed in the filesystem to ".a.b" before src/lib-storage/index/maildir/maildir-storage.c rename_subfolders() is called, which then finds ".a.b", assumes "b" was a subfolder of "a" so renames it. The following may or may not be an appropriate fix. It certainly feels rather ad hoc and I've not thought too deeply about other circumstances where this code is called. I'd certainly appreciate a second opinion. diff -r 8d6433652a33 src/lib-storage/index/maildir/maildir-storage.c --- a/src/lib-storage/index/maildir/maildir-storage.c Sun Sep 30 18:03:17 2007 +0300 +++ b/src/lib-storage/index/maildir/maildir-storage.c Mon Oct 01 20:13:27 2007 +0100 @@ -937,6 +937,10 @@ static int rename_subfolders(struct inde t_push(); old_listname = t_strconcat(oldname, names[i], NULL); + if (strcmp(old_listname, newname) == 0) { + t_pop(); + continue; + } new_listname = t_strconcat(newname, names[i], NULL); oldpath = maildir_get_path(storage, old_listname); newpath = maildir_get_path(storage, new_listname);

[Dovecot] API problem (noob)
by Lars Stavholm 20 Oct '07

20 Oct '07

I'm a bit of a newbie, especially when it comes to dovecot internals, but nevertheless, I need some help: I'm working on a dovecot plugin, and I would like to copy a mail message from the mail store out to a temporary file, less a few headers: static const char *const exclude_headers[] = { "X-DSPAM-Signature" } strcpy(fname, mktemp(fname)); fd = creat(fname, 0600); mail_get_stream(mail, NULL, NULL, &input); output = o_stream_create_fd_file(fd, 0, TRUE); input = i_stream_create_header_filter(input, HEADER_FILTER_EXCLUDE | HEADER_FILTER_NO_CR, exclude_headers, N_ELEMENTS(exclude_headers), null_header_filter_callback, NULL); o_stream_send_istream(output, input); But all I get in the temp file is the message body, i.e. no headers at all. What am I doing wrong here? My understanding (or hope:) of what the function i_stream_create_header_filter() is supposed to do might not be accurate: I was hoping that it would exclude the aforementioned headers, but leave the rest of the headers as is. Any help appreciated /Lars

[Dovecot] Better flagging of errors on logs?
by Francisco Reyes 20 Oct '07

20 Oct '07

Last night dovecot died because of time changed backward. I noticed that the line from dovecot read Oct 9 01:00:44 mailstore16 dovecot: Time just moved backwards by 132 seconds. This might cause a lot of problems, so I'll just kill myself now. Shouldn't such lines have the word "Error" or "Fatal"? If I set the log_path = to a file, will syslog messages still be generated?

[Dovecot] Dovecot raw backtrace when copying to folder
by Julian Cowley 20 Oct '07

20 Oct '07

Seeing a problem with a certain user causing dovecot to crash when copying mail to a folder. This looks similar to a bug someone on the mailing list posted recently. Since the backtrace mentions the index, I tried deleting all of the index files for the user (including subfolders) but it had no effect. Seems that the bug still happens when creating the index for the first time. Unfortunately, I can't pin down if there is a particular message causing the problem but I'll see if I can track it using strace. Lines are broken for clarity. This is dovecot 1.0.5 on CentOS 4.5.

[Dovecot] User database ldap lookups and sasl
by olivier castan 20 Oct '07

20 Oct '07

Hello I'm currently trying to use Active Directory with Unix extensions to store UID, GID and homedir and retrieve them with ldap I don't want to allow anonymous bindings and I would rather not use TLS and manage a PKI. So I'm trying to use SASL to do a Kerberos authentication for Dovecot against AD LDAP. I'm currently getting GSSAPI errors about the lack of "credentials cache". Looking at similar cases where services act as clients, like using nss_ldap for unix host accounts, I understand the credentials cache should be initiated by an external program (cron and startup script), at least with the TGT and maybe the TGS for ldap. Since usually kerberosv5 cache is based on the user id ( /tmp/krb5cc_0 for root) there's an option in ldap.conf (krb5_ccname) to set the filename (/etc/.ldapcache in nss_ldap tutorials) for this cache. Is there any way to do this with dovecot-ldap.conf or should I try to use "auth user" default cache filename ? Thanks in advance

[Dovecot] Howto make deleted itens visible to users?

Hi! I'm using lazy_expunge to backup that are deleted/expunged, but I would like it to be visible to the user. I tried something like: namespace private { prefix = .EXPUNGED/ separator = / location = maildir:~/Maildir/.Apagadas } namespace private { prefix = .DELETED/ separator = / location = maildir:~/Maildir/.Apagadas } namespace private { prefix = .DELETED/.EXPUNGED/ separator = / location = maildir:~/Maildir/.Apagadas/ } But neither OE nor TB shows the messages. (yes, i subscribed the ".Apagadas" maildir). Anybody can give me this little tip? Thanks a lot. []'s, Catunda! !DSPAM:46f1105715318362916074!

[Dovecot] Mail client kill imap-login process
by dovecot acc 20 Oct '07

20 Oct '07

Hi, In my env we have quite a number of old PC which are running windows95. I have installed the thunderbird and outlook97 with the right configuration to dovecot. Everytime I starts the mail client it shows the following, dovecot: Oct 09 10:56:45 Info: imap-login: Disconnected: rip=172.24.65.60, lip=172.24.66.24 only then it shows the login screen. After submit the password, it doesn't seems to login properly. If I use the Outlook Express, it runs ok on the same machine? I can send and read email. I trace the process using strace but it failed since the pid got killed everytime I starts that two mail client. In order to make sure my dovecot run correctly, I run all mail clients from XP and it works like charm. Can someone share with my what should I do next or how to debug further? Thanks.

[Dovecot] Disconnects in log
by Jackie Hunt 20 Oct '07

20 Oct '07

Hi all, I need some help interpreting the info I'm seeing in the dovecot logs. I have a user using Outlook who is having connectively problems. Below is a sample of what the Dovecot log is showing. Can anyone explain to me why multiple logins occur within a few seconds of each other? Also, as I understand it, the "Disconnected" messages mean the kernel told Dovecot the connection was closed. I'm trying to figure out why I'm seeing so many of these. And why they seem to occur shortly after a login. Thanks for any insight!

[Dovecot] verbose_proctitle for proxy processes?
by Onno Molenkamp 20 Oct '07

20 Oct '07

Hi, We're using Dovecot to proxy incoming POP3 and IMAP connections to the right server. We'd like to be able to see what connections are currently open on the proxy servers, without having the parse the log file. For normal mail processes it's possible to use verbose_proctitle for this purpose, but this setting doesn't work for proxy/login processes. Is it possible to do something similar for proxy processes? Even without displaying the username and IP address, it would be useful to be able to see the difference between normal (idle/active) login processes, and proxy processes. Onno

by Maykel Moya 20 Oct '07

20 Oct '07

I'm migrating to LDAP mi local users, there is the auth section of my dovecot.conf -- auth default { mechanisms = plain socket listen { master { path = /var/run/dovecot/auth-master mode = 0660 user = dovecot group = nusers } } passdb ldap { args = /etc/dovecot/dovecot-ldap.conf } passdb pam { } userdb ldap { args = /etc/dovecot/dovecot-ldap.conf } userdb prefetch { } userdb passwd { } user = root } -- The idea is to try to find the user in the directory and if it isn't found then fallback to a local user lookup. My quota configuration is -- plugin { quota = maildir:storage=10240:ignore=Trash } -- I have some users with particular quotas. With LDAP lookups, there is no problem, in those cases I simply put their particular quota values in their entries and pass it to dovecot via user_attrs. I wonder how to do the same for local users, I mean, to have the ability of specifying particular quotas for some local users. Another doubt is how to express to Dovecot that a user have no quota at all, could I use 0? Regards, maykel

[Dovecot] dovecot and imap session forwarding
by Omer Faruk SEN 20 Oct '07

20 Oct '07

Hi, I was trying to install a qmail-ldap cluster. I have successfully setup dovecot to authenticate against ldap directory. But what I need is to enable imap session forwarding for qmail-ldap. For example when a user connects to a imapserver if the real mailhost of this user is different than the one that is connected so session is forwarded to real mailhost. Normally we can do that with courirer imap using auth_imap binary that comes with qmail-ldap which handles session forwarding. I have done this but got error auth_executable = /var/qmail/bin/auth_imap . Obviously it won't work. But I am not sure where to put /var/qmail/bin/auth_imap http://www.qmail-ldap.info/dovecot.php and http://www.qmail-ldap.info/imap_courier.php page shows a bit information about where to put it. -- Best regards, Omer mailto:omer@faruk.net

[Dovecot] thunderbird and email duplication
by Alexander Banthien 20 Oct '07

20 Oct '07

Hi all, I have recently switched over to Dovecot from CourierIMAP trying for some speedup, which I did get. Installation went OK, so all seemed fine. But suddenly I realised, that incoming emails are replicating themselves. This seems only to happen when connected with Thunderbird. I am also using Squirrelmail and KMail as clients which don't seem to show the behaviour. It seems to happen only for mails received during a Thunderbird session. When I close TBird and reopen it, only newly received messages will show the funny behaviour. The emails are real file copies in the Maildir, I have checked that. Running Dovecot on Debian Etch: dovecot --version: 1.0.0 (this is Debian package 1:1.0.0-1~bpo.1 from backports. I have tried the main package from Debian aswell, same result) with qmail delivering the mails to a Maildir without Dovecot's LDA. Clients: Thunderbird 2.0.0.6 on WinXP over Wireless LAN (tried Thunderbird/Iceweasel on Debian aswell) Squirrelmail and KMail (both running on the same box as Dovecot) don't show that behaviour. Has anybody seen anything similar or have any advice on what to look for? I would like to stick with Dovecot but the way it is looking now, I find working with emails near impossible.

[Dovecot] how to deliver when username and email differ
by Cory Coager 20 Oct '07

20 Oct '07

I have an Active Directory virtual setup and am using LDA to deliver to local recipients. Today I found a big problem with my configuration and not sure if this is fixable. Some of the users have multiple email addresses and the %n variable for user doesn't match their actual username. So if I have realname "Joe Bob" with a username of "joe" and an email of "jbob(a)somewhere.com", deliver will try to deliver to "jbob" and this is wrong. Here is the relevant part of my ldap config: user_attrs = mail,postOfficeBox=home user_filter = (|(mail=%n@%d)(proxyAddresses=%n@%d)(sAMAccountName=%u)) pass_attrs = mail,postOfficeBox=home pass_filter = (|(mail=%n@%d)(proxyAddresses=%n@%d)(sAMAccountName=%u)) Somehow I need to change the username from the LDAP lookup but it seems that the mail attribute does this already. If I switch the mail attribute with sAMAccountName the domain becomes NULL. Anyone know if this is fixable?

[Dovecot] Dovecot v1.0.3 -> Sieve "redirect" command returning Sendmail exit status 75
by Elisamuel Resto 20 Oct '07

20 Oct '07

Hello! My local setup here is Exim 4.68, DSPAM 3.8.0 and Dovecot 1.0.5. Entirely on MySQL tables for virtual hosts and authentication. Dovecot does the authentication for Exim. What I am having problems with, is a simple sieve script to redirect a message that matches the "X-DSPAM-Result" header as "Spam" to another email address. When this rule matches, deliver returns in the log (which is attached) that "Sendmail process terminated abnormally, exit status: 75" What would cause this, and how can I resolve it? Thanks. -- Elisamuel Resto <samuel(a)dragonboricua.net> ID: 0x18615F19 / FP: B66D 1C2A E8EE B922 1D9C D98F D2D5 FB61 1861 5F19

[Dovecot] Problem with bodystructure/partial fetch using 1.1*
by mikkel＠euro123.dk 20 Oct '07

20 Oct '07

Hi there I'm using dovecot-1.1b2/b3 with deliver. All information is stored in an SQL database and no errors related to this issue are written to the logs (actually I get no errors at all). I've run into at problem; FETCH BODYSTRUCTURE is broken after upgrading to dovecot 1.1b2 (same issue with 1.1b3). BODUSTRUCTURE only returns information from the first section (with incorrect content-type/disposition) and discards everything else. This problem is somehow related to deliver; IMAP returns the correct BODYSTRUCTURE for e-mails received before the upgrade, but an incorrect for ones received after the upgrade. This tells me that IMAP is working properly but somehow the MIME sections are being corrupted doing mail delivery (if I fetch the complete body nothing seems to be wrong). Also if I fetch a section something is not right - instead of just the section I get part of the Content-type header as well (but only half the header). Obviously this makes various webmail clients go somewhat crazy while Outlook/Thunderbirds dont mind (since they fetch the complete body and do the MIME parsing themselves). These are my compile options (GCC 3.4.3 on Solaris 10): CPPFLAGS=-I/opt/pkgsrc/pkg/include/mysql LDFLAGS=-L/opt/pkgsrc/pkg/lib/mysql ./configure --prefix=/opt/freeware/dovecot-1.1b2 --with-pop3d --with-deliver --with-mysql --with-prefetch-userdb --with-sql --with-gnu-ld --with-ssl=no --enable-header-install make; make install Everything else works flawlessly.

[Dovecot] In 1.1.beta3, COPY cmd results in msg with Content-length: 0 and no text

[Dovecot] Operations error with AD connections
by Maarten Vanraes 19 Oct '07

19 Oct '07

Hello, dovecot version: 1.0.beta3-3ubuntu5.5 OS: 2.6.15-26-server i686 GNU/Linux Ubuntu dapper filesys: ext3 authentication is with ldap (Active Directory) the problem is that after a while with a number of pop3 connections (8 people who have checking every 5 minutes), the ldap_search gives 'Operation Error' . we have tried to use the global catalog, but that doesn't solve the problem. the binding is the problem, we must use binding, cause we don't get a userPassword field. Right now, we have switched to courierLDAP and it works for now, we'll have to see if it persists (we have set an LDAP timeout variable, but don't know if it's related.) The thing is that we have lots of places where can setup something like this with AD, and that for now, we'll probably use courier. dovecot-ldap.conf: hosts = 172.17.80.1:3268 dn = CN=SPIC,OU=Beheerders,OU=Zonnegroep,DC=zonnewende,DC=local dnpass = xxxxxxxxx auth_bind = yes ldap_version = 3 base = dc=zonnewende, dc=local user_filter = (mail=%u) pass_attrs = uid=user,userPassword=password pass_filter = (mail=%u) user_global_uid = 5000 user_global_gid = 5000 any ideas on how to solve it?

[Dovecot] performance?/connectivity? issues after server upgrade
by Udo Rader 18 Oct '07

18 Oct '07

Hi, we are facing some weird performance issues after we upgraded on of our mail servers to a new Opteron 64bit machine. The problem we are facing is that mail retrieval from external clients is incredibly slow. Fetching a mail with say a size of 3MB takes 7 minutes vs. sending exactly the same mail back to our postmaster account is only a question of seconds. I've verified this with various customers and thus I am completely lost here. The only service affected with this massive slowdown seems to be dovecot but unfortunately I cannot think of a way to debug the issue ... System load is absolutely minimal. % dovecot -n # 1.0.5: /etc/dovecot/dovecot.conf log_path: /var/log/dovecot.log protocols: imaps imap pop3 listen: 81.16.98.99 ssl_listen(default): 81.16.98.99 ssl_listen(imap): 81.16.98.99 ssl_listen(pop3): ssl_cert_file: /usr/bestsolution/ssl/certs/mail.bestsolution.at.pem ssl_key_file: /usr/bestsolution/ssl/private/mail.bestsolution.at.pem ssl_parameters_regenerate: 24 disable_plaintext_auth: yes login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login first_valid_uid: 9 mail_extra_groups: mail default_mail_env: mbox:~/mail/:INBOX=/var/mail/%u mail_location: mbox:~/mail/:INBOX=/var/mail/%u mmap_disable: yes lock_method: dotlock maildir_copy_with_hardlinks: yes mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %v.%u auth default: mechanisms: digest-md5 cram-md5 login passdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf userdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix Any ideas welcome :-) -- Udo Rader bestsolution.at EDV Systemhaus GmbH http://www.bestsolution.at

[Dovecot] Released v1.1.beta3
by Timo Sirainen 18 Oct '07

18 Oct '07

http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta3.tar.gz http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta3.tar.gz.sig Please try and report any bugs. Beta2 still had a few bad bugs, but I'm hoping this release is near a usable state. I've been a bit busy with school lately so I haven't had time/energy to answer mails in here. The main reason has been this lab course (biochemistry) which ends on friday, so I'll try to start answering mails sometimes next week. Changes since beta2: - SORT fixes. Still buggy? - If Date: header doesn't exist or is broken, fallback to INTERNALDATE (as required by newer sort drafts, which I hadn't noticed before, v1.0.6 will have this too) - Log fatals/panics as such, instead of converting them to errors. - Don't bother logging "returned error 89" if the child process logged a fatal before that. - dovecot.index.cache file may have been updated wrong when saving messages causing all kinds of problems if it was - Some crashfixes

Hello all Tomorrow is the day , I'm gonna migrate all our mailboxes and imap folders from our old mailhub to the new one. In the same time I will migrate from UW to Dovecot , I've read all the stuff about it on the Dovecot web site. I have one question , do I have to care about the .imap cache directory created by Dovecot in any way or will it be "all automatic" when starting Dovecot ? Many thanks -- Cordialement Frank Bonnet

[Dovecot] iPhone 1.1.1 problems.
by Mike Meyer 17 Oct '07

17 Oct '07

I'm having problems with the iPhone client in the 1.1.1 version of the iPhone software. Things with other clients work fine, and the iPhone worked fine before it was upgraded to 1.1.1. Other phones on 1.1.1 failed. I'm still working on testing against the client with the iPhone 1.0.2 software on it. The problem is that the client simply doesn't connect to dovecot. I can see the packets passing back and forth in a number of ways, but haven't been able to see the contents. I tried turning on raw logging, but don't get log files for accesses from the iPhone. What I get are lines like so: Oct 13 00:08:34 bhuda dovecot: imap-login: Disconnected: rip=xxx.xxx.xxx.xx2, lip=xxx.xxx.xxx.xx1, TLS Turning off SSL both ways, and the message changes to: Oct 13 18:21:38 bhuda dovecot: imap-login: Aborted login: rip=xxx.xxx.xxx.xx2, lip=xxx.xxx.xxx.xx1 Tweaking the logging in the firewall reveals something interesting: apparently the phone makes the connection to 993, then dovecot drops the connection, but the phone keeps sending to it (and yes, I've tried setting the firewall to allow arbitrary traffic between the phone and the server). So, first question: is anyone who has clients using iPhone software version 1.1.1 working willing to share config information? Second question: suggestions for things to try to solve the problem? (Other than talk to apple as that process is underway)? For instance, a recipe to sniff the text of the interchange? Final question: Any other information I can provide that might help debug this?

[Dovecot] namespace prefix issue with avelsieve and dovecot v1.1beta2

Hi, I have installed dovecot v1.1.beta2 with the sieve plugin v.1.1.2. I have configured the following namespace: namespace: type: private separator: . prefix: INBOX. location: inbox: yes hidden: no list: yes When I create a rule which should move messages into the subfolder "Junk", Dovecot's deliver seems to ignore the namespace and creates a new folder .INBOX.Junk . I think I read somewhere that in Dovecot v1.1+ deliver supports namespaces? Or have I misconfigured something? Thank you!

[Dovecot] Error: net_connect(/var/run/dovecot/auth-master) failed: Resource temporarily unavailable

I get this assertion failure: file maildir-save.c: line 456 (maildir_save_finish): assertion failed: (ctx->seq != 0) once a while when I APPEND messages to a folder. My plugin doesn't touch the ctx, especially not the internal maildir one, but I have no idea where to start looking. Any hints? johannes

Version: 1.0.beta8 Is it possible to listen on just specific IP addresses as opposed a single IP or just all IPs on the same server? Thanks, LDB

[Dovecot] dovecot 1.1beta2 and dovecot-sieve 1.1.2 - crash in LDA

12 Oct '07

Hi, I've upgraded to dovecot 1.1beta2 and the latest dovecot-sieve release yesterday and have one single mail that cannot be delivered repeatedly. Log (reformatted): Oct 12 15:19:19 vs02 deliver(bernilrz): pool_data_stack_realloc(): stack frame changed Oct 12 15:19:19 vs02 deliver(bernilrz): Raw backtrace: /usr/local/libexec/dovecot/deliver(i_syslog_panic_handler+0x1e) [0x47117e] -> /usr/local/libexec/dovecot/deliver [0x470eac] -> /usr/local/libexec/dovecot/deliver [0x47929b] -> /usr/local/libexec/dovecot/deliver [0x46f3e3] -> /usr/local/libexec/dovecot/deliver(buffer_write+0x9d) [0x46f70d] -> /usr/local/libexec/dovecot/deliver [0x469aaf] -> /usr/local/libexec/dovecot/deliver(message_header_decode+0x104) [0x469c14] -> /usr/local/libexec/dovecot/deliver(message_header_decode_utf8+0x4b) [0x469d4b] -> /usr/local/libexec/dovecot/deliver [0x43f3eb] -> /usr/local /libexec/dovecot/deliver(index_mail_get_headers+0x42) [0x4401c2] -> /usr/local/lib/dovecot/lda/lib90_cmusieve_plugin.so [0x2b662df67d87] -> /usr/local/lib /dovecot/lda/lib90_cmusieve_plugin.so [0x2b662df716e8] -> /usr/local/lib/dovecot/lda/lib90_cmusieve_plugin.so(sieve_eval_bc+0x395) [0x2b662df72665] -> /usr/local/lib/dovecot/lda/lib90_cmusieve_plugin.so(sieve_execute_bytecode+0xfa) [0x2b662df77daa] -> /usr/local/lib/dovecot/lda/lib90_cmusieve_plugin.so(cmu_sieve_run+0x318) [0x2b662df689b8] -> /usr/local/lib/dovecot/lda/lib90_cmusieve_plugin.so [0x2b662df66d96] -> /usr/local/libexec/dovecot/deliver(main+0xe74) [0x417d24] -> /lib/libc.so.6(__libc_start_main+0xf4) [0x2b662da15b44] -> /usr/local/libexec/dovecot/deliver [0x416079] All other mails work fine, so there is probably something corner case here.

[Dovecot] Logging client commands (patch)
by Zach Bagnall 12 Oct '07

12 Oct '07

This might be useful to someone so I'll throw it out there. Patch against 1.0.5 adds support for two new configuration params: pop3_debug_client_commands = TOP, RETR, DELE imap_debug_client_commands = FETCH, DELETE Obviously add in whichever ones you're interested in, or none, or comment them out completely. It'll log the appropriate events: Oct 12 18:30:18 kea dovecot: IMAP(zach): Client command: FETCH The parameters are included for POP3 events. Wasn't sure quite how to do the same for IMAP and for my purposes it's not too important so imap command parameters aren't logged. Running smoothly here with a few dozen IMAP and POP3 users. Not suggesting this gets added to the codebase - I just needed it to help debug some other IMAP software and thought it might be useful. Zach.

[Dovecot] UIDL format for old UW pop3
by Oliver Hookins 11 Oct '07

11 Oct '07

Hi, we're trying to migrate from UW imap 2001a-10, which doesn't seem to use the UIDL format documented in the wiki. It seems to use a 16 character long MD5 hash of something. I've tried configuring Dovecot to do the same but the value comes out differently. The main thing that I can see is getting in the way is that the UIDL format is not documented sufficiently. There is no description of using numbers to restrict the length of the output, and no documentation of special features like X or M. Can someone shed some light on these? -- Regards, Oliver

[Dovecot] Quota Display with Horde / IMP ( WebMail Client )
by edwardspl＠ita.org.mo 11 Oct '07

Dear All, For the Dovecot.conf : protocol imap { mail_plugins = quota imap_quota mail_plugin_dir = /usr/lib/dovecot/imap } plugin { quota = maildir } For /var/spool/mail : -rw------- 1 root root 7168 Sep 24 23:02 aquota.group -rw------- 1 root root 8192 Sep 24 18:05 aquota.user -rw------- 1 edward mail 301709 Sep 24 23:27 edward But the Quota display is un-limited status... So, what mistake about the config ? Mine is FC6 System ! Thanks ! Edward.

[Dovecot] GSSAPI Cross-Realm Patch
by Zachary Kotlarek 10 Oct '07

10 Oct '07

I've written a GSSAPI cross-realm auth patch for people not lucky enough to have the __gss_userok function, though it should apply pretty cleanly with that patch in place as well. The patch is available at: http://zinux.cynicbytrade.com/svn/servers/dovecot/cross-realm.diff.bz2 It works for me on MIT-kerb, and I tested compilation against heimdal, but I don't have a cross-realm setup to test functionality under heimdal (though I also have no reason to think it wouldn't work). Since neither MIT nor heimdal provide a gss_userok() function, I used the krb5_userok() function. So if you're using a mechanism other than krb5 this won't work. But it's the same thing that OpenSSH and the apps distributed with heimdal do, so it seemed relatively safe. I also choose to append the krb5_userok() check rather than replace the gss_compare_name() check -- that way same-realm auth works for non-krb5 mechanisms, and my new code doesn't get called unless the same-realm check fails. If you don't care about other mechanisms it would be faster to bypass the gss_compare_name() check entirely. If this is something you'd like to mainline I'd be happy to standardize the coding style -- just point me to a style definition document. And if it doesn't hit the mainline I expect to maintain it for the foreseeable future, with updates at the same URL. Zach

[Dovecot] Dovecot, postifx, virtual domains and deliver, what about luser_relay/fallback_relay?
by Alexander Hoogerhuis 10 Oct '07

10 Oct '07

I've read documentation (obviously not the right parts) and googled, but I can't seem how to solve this simple problem: I have a machine running postfix/dovecot and using virtual domains, delivery happens with dovecot's LDA. I also have an Exchange machine that I have to house some of the users of a given domain. How can I tell either postifx in general or dovecot's LDA that whatever specific user that cannot be found in the virutal setup can be pawned off to a given relay-server which will sort it out? -A

[Dovecot] FW: IMAP proxy with dovecot and hostname
by Limperis Antonis 10 Oct '07

10 Oct '07

Good morning dovecot users I read in http://wiki.dovecot.org/PasswordDatabase/ExtraFields/Proxy that dovecot need ip address in host field and then "This field is required. Note that currently it's required to use an IP address since no DNS resolving is done.". I use a qmail cluster and Courier IMAP. In this system used the ldap field mailhost for proxy functionality with dns name as value. Is there a plan to add the DNS resolving to dovecot in host field; Is there any patch; Thanks Antonis

[Dovecot] User database ldap lookups and sasl
by Olivier Castan 10 Oct '07

10 Oct '07

Hello I'm currently trying to use Active Directory with Unix extensions to store UID, GID and homedir and retrieve them with ldap. I don't want to allow anonymous bindings and I would rather not use TLS and manage a PKI. So I'm trying to use SASL to do a Kerberos authentication for Dovecot against AD LDAP. I'm currently getting GSSAPI errors about the lack of "credentials cache". Looking at similar cases where services act as clients, like using nss_ldap for unix host accounts, I understand the credentials cache should be initiated by an external program (cron and startup script), at least with the TGT and maybe the TGS for ldap. Since usually kerberosv5 cache is based on the user id ( /tmp/krb5cc_0 for root) there's an option in ldap.conf (krb5_ccname) to set the filename (/etc/.ldapcache in nss_ldap tutorials) for this cache. Is there any way to do this with dovecot-ldap.conf or should I try to use "auth user" default cache filename ? Thanks in advance

[Dovecot] SpamAssassin and Public Namespace
by James 09 Oct '07

Hi I know i might get flamed for asking this in the dovecot mailing list instead of the spamassassin one but i thought someone might be kind enough to help anyway.
