Correct. If the folder does not exist, maildrop will create it on first delivery. If the end user deletes the folder, maildrop will recreate the folder on the next message delivery to that account.

[Dovecot] 1.1b1 initial pop3 login: assertion failed
by David Jonas 01 Oct '07

01 Oct '07

Currently running 1.0.2 with 1.1b1 listening on a different port. On first pop3 login on 1.1b1 I received an immediate disconnect (I was testing with telnet) with the log entries below. Subsequent logins work fine. Other accounts that I tried did not have the same problem. So this is probably isolated to some bad indexes or something, but I thought I should let Timo know. Regards, David Here is what I found in the logs: ----------------------------------------- Sep 28 15:51:14 kelly-a dovecot: POP3(xxx(a)xxxxx.com)[8112]: Fixed index file /home/vmail/x/xxxxx.com/xxx/Maildir/dovecot.index: first_recent_uid 0 -> 1 Sep 28 15:51:14 kelly-a dovecot: POP3(xxx(a)xxxxx.com)[8112]: file mail-index-view-sync.c: line 304 (mail_index_view_sync_begin): assertion failed: (view->index->map->hdr.messages_count >= ctx->finish_min_msg_count) Sep 28 15:51:14 kelly-a dovecot: POP3(xxx(a)xxxxx.com)[8112]: Raw backtrace: pop3 [0x80cd42e] -> pop3(i_fatal+0) [0x80cce93] -> pop3(mail_index_view_sync_begin+0x228) [0x80a91d2] -> pop3(index_mailbox_sync_init+0xac) [0x8093abe] -> pop3(maildir_storage_sync_init+0x11e) [0x80646a1] -> pop3(mailbox_sync_init+0x1b) [0x80bb428] -> pop3(mailbox_sync+0x18) [0x80bb49b] -> pop3 [0x80582f5] -> pop3(client_create+0x237) [0x80587ac] -> pop3 [0x805afe8] -> pop3(main+0x95) [0x805b0e4] -> /lib/tls/libc.so.6(__libc_start_main+0xd3) [0x477de3] -> pop3 [0x80581ed] Sep 28 15:51:14 kelly-a dovecot: child 8112 (pop3) killed with signal 6 Other information ------------------------ $ cat /etc/redhat-release Red Hat Enterprise Linux ES release 4 (Nahant Update 5) $ uname -r 2.6.9-42.0.10.ELsmp $ ./dovecot -n # 1.1.beta1: /usr/local/dovecot-1.1/etc/dovecot.conf base_dir: /var/run/dovecot-1.1/ protocols: imap pop3 listen(default): *:9143 listen(imap): *:9143 listen(pop3): *:9110 ssl_disable: yes login_dir: /var/run/dovecot-1.1/login login_executable(default): /usr/local/dovecot-1.1/libexec/dovecot/imap-login login_executable(imap): /usr/local/dovecot-1.1/libexec/dovecot/imap-login login_executable(pop3): /usr/local/dovecot-1.1/libexec/dovecot/pop3-login login_greeting: postoffice.no-ip.com (1.1) login_log_format_elements: user=<%u@%d> method=%m rip=%r lip=%l %c login_process_per_connection: no verbose_proctitle: yes first_valid_uid: 89 mail_uid: vmail mail_gid: vmail mail_executable(default): /usr/local/dovecot-1.1/libexec/dovecot/imap mail_executable(imap): /usr/local/dovecot-1.1/libexec/dovecot/imap mail_executable(pop3): /usr/local/dovecot-1.1/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/local/dovecot-1.1/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/dovecot-1.1/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/dovecot-1.1/lib/dovecot/pop3 mail_log_prefix: %Us(%u)[%p]: pop3_uidl_format(default): %08Xu%08Xv pop3_uidl_format(imap): %08Xu%08Xv pop3_uidl_format(pop3): %f pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain login digest-md5 cram-md5 user: nobody username_translation: %@ username_format: %Lu verbose: yes passdb: driver: sql args: /usr/local/dovecot-1.1/etc/dovecot-sql.conf userdb: driver: prefetch socket: type: listen client: path: /var/run/dovecot-1.1/auth-client mode: 432 plugin: quota: dict:user::proxy::quota dict: quota: mysql:/usr/local/dovecot-1.1/etc/dovecot-dict-quota.conf

[Dovecot] v1.1.beta2 - maildir quota calculation problem
by Andrew Pavlenko 01 Oct '07

01 Oct '07

I have a problem with the maildir quota plugin. Any imap operations cause the plugin to recalculate the mailbox size and put the new value in the second line of the maildirsize file, while the third line always contains the size of the latest operation. So the resulting sum is incorrect. Moreover, quota-warning is not working either. Have anybody else met such problem? mail# ./dovecot -n # 1.1.beta2: /usr/local/etc/dovecot.conf ... mail_plugins(default): quota mail_log mail_plugins(imap): quota mail_log mail_plugins(pop3): quota mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 ... plugin: quota: maildir quota_rule: *:storage=10240 quota_warning: storage=75%% /usr/local/etc/quota-warning.sh 75

[Dovecot] Mixed Courier POP3 and Dovecot IMAP environment
by Jan van den Berg 01 Oct '07

01 Oct '07

Hi, Currently we support Courier POP and IMAP for all our users (users can use IMAP as well as POP at the same time). We are thinking about moving to Dovecot; but first moving away from Courier IMAP to Dovecot IMAP (and maybe later also move to Dovecot POP). This would create a mixed environment; after some research I have the following questions. To not break POP3 Courier and still be able to use Dovecot IMAP: - I have to use the namespace prefix in the dovecot.conf file: I read this in the wiki. - "Patch" the source so Dovecot IMAP will look for/use 'courierimapuiddb' instead of 'dovecot-uidlist': otherwise I guess POP3 and IMAP users will have different UID files, right? Is this smart or will this still break the UID file? - "Patch" the source so Dovecot IMAP will look for/use 'courierimapsubscribed' instead of 'subscriptions' of should I just go with the renaming of the files? I'm thinking about patching so the transition can be as transparent as possible: Also if anything might go wrong in production I want to be able to switch back to the 'old' Courier IMAP (without renaming files etc.) Any thoughts on this? Cheers, Jan

http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta2.tar.gz http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta2.tar.gz.sig Several bug/crashfixes. deliver now supports -a parameter (see http://wiki.dovecot.org/LDA) which allows Sieve plugin v1.1.2 to use envelope :detail "to" checks. I also did one more API change for mailbox_transaction_commit*(). There's probably something still wrong with SORT command, but other than that I've fixed everything that's been reported.

[Dovecot] Maildir ignore
by Tomas Horacek 01 Oct '07

Hello there. I do like Dovecot so far, but ran into problem I cant seem to solve, maybe someone can point me into right direction please. I am running version 1.0.rc15 on CentOS 5 Linux i386 system, ext3 fs. The problem is I cant get the maildir: and :ignore to work together. Here is my SQL query, that includes the Quota field. # cat /etc/dovecot-sql.conf | grep -i quota user_query = SELECT maildir AS home, 901 AS uid, 901 AS gid, CONCAT('maildir:storage=', floor(IF(quota!=0, quota,-1)/1000), ':ignore=Trash') AS quota FROM mailbox WHERE username = '%u' AND active = '1' Even Dovecot agrees it seems correct. # cat /var/log/maillog | grep kaktus | grep quota\= | tail -n1 Sep 30 23:37:33 XXXXXX dovecot: auth(default): master out: USER 5 XXX(a)XXX.cz home=XXX uid=901 gid=901 quota=maildir:storage=1024:ignore=Trash I hope this is the correct way. Looking at IMAP communication with Wireshark, the server seems to ignore my settings. 118 uid copy 22 Trash\r\n 118 NO Quota exceeded\r\n Anyone can help me, please ?

[Dovecot] dovecot-dspam plugin & virtual users
by Wicher Minnaard 30 Sep '07

30 Sep '07

Hi list, hi Johannes, I'm trying to use the dovecot-dspam plugin ( http://johannes.sipsolutions.net/Projects/dovecot-dspam-integration ) with vpopmail's virtual users. All seems well, except for the fact that dspam should be called with '--user currentuser(a)currentdomain.com' at line 157 here: http://johannes.sipsolutions.net/Projects/dovecot-dspam-integration/beta7-c… For my needs, 'currentuser@currentdomain' could be taken as the login name I use for logging in to Dovecot. As I'm not a C-programmer by a long shot, I was wondering if one of you could help me use the bincimap-API to import the login name into a variable so I can use that variable to construct a suitable dspam-command. Hope this is possible! Regards, Wicher Minnaard

[Dovecot] dovecot dspam plugin using libdspam

Hi, I've found the dovecot dspam plugin and looked at the code. I forks and calls the dspam binary for every mail. I didn't like this behavior, so I've migrated it to use libdspam. The plugin still needs more love: * Use cmake instead of a Makefile * Make the spam folder configurable in the dovecot.conf * Code cleanup and more comments. Please test. Comments and patches are welcome ;) http://www.cynapses.org/tmp/dovecot-dspam-plugin-0.1.tar.gz Cheers, -- andreas -- http://www.cynapses.org/ - cybernetic synapses

[Dovecot] Subaddress Extension in sieve plugin
by Frank Behrens 30 Sep '07

30 Sep '07

Hello! With many MTAs it is possible to use a special form of adressing: subaddresses or "plussed addresses". For sendmail you can read some information on http://www.sendmail.org/m4/misc_features.html http://www.unix.org.ua/orelly/networking/sendmail/ch24_04.htm#SML2-CH-24-SE… In a sieve filter you can analyse these special detail values, the syntax is described in RFC3598 (http://tools.ietf.org/html/rfc3598) The current deliver with sieve plugin for dovecot seems to support this RFC, but has the detail information not available. If I use require ["subaddress", "fileinto", "reject"]; require "envelope"; if envelope :detail "to" "junk" { fileinto "junk"; } the rule is not triggered, because the detail information from envelope is not available. Deliver gets the user information only via command line switch "-d". I did not analyse the problem very deep, but I believe we should introduce a new command line parameter for deliver, so deliver can pass the detail information to the sieve plugin. With that parameter you are able to pass the detail information from sendmail to devecot's deliver in the same way procmail is handled (procmail uses -a parameter). To avoid confusion: deliver has already a parameter -m to specify a different mailbox. In the described case the mailbox should be determined by the sieve filter, not via command line parameter. Existing workaround: Because I need this functionality I wrote a quick (and dirty?) workaround. Sendmail does not call deliver directly, but a wrapper program, that adds an additional "Delivered-To" header line. So the detail information may be processed with if address :detail ["Delivered-to"] "junk" { but I would prefer to call deliver directly. What do you think, is it a useful extension and does it work?

[Dovecot] v1.1.beta1 POP3 delete problem
by arvids 30 Sep '07

30 Sep '07

Hello, POP3 server does not delete mails when user quits POP3 session, but only at the next login. It looks so - user logs in with USER and PASS commands, at this moment new messages are moved from /new to /cur maildir folder. Then messages are deleted with DELE command(before deleting there can be other POP3 commands) and the user quits session. The server says "+OK Logging out, messages deleted.", but in fact messages are not deleted from the disk and stays in /cur folder. And these messages are deleted only when user logs in next time. dovecot -n: # 1.1.beta1: /usr/local/dovecot/etc/dovecot.conf base_dir: /var/run/dovecot/ syslog_facility: local0 protocols: pop3 ssl_disable: yes disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/local/dovecot/libexec/dovecot/pop3-login login_greeting: Server. login_process_per_connection: no login_process_size: 64 verbose_proctitle: yes first_valid_uid: 95 first_valid_gid: 95 mail_uid: 95 mail_gid: 95 mail_location: maildir:~/Maildir mail_debug: yes fsync_disable: yes mail_executable: /usr/local/dovecot/libexec/dovecot/pop3 mail_plugins: quota mail_plugin_dir: /usr/local/dovecot/lib/dovecot/pop3 pop3_enable_last: yes pop3_client_workarounds: outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain login digest-md5 cram-md5 apop cache_size: 2048 cache_ttl: 28800 cache_negative_ttl: 60 user: doveauth verbose: yes debug: yes debug_passwords: yes passdb: driver: sql args: /usr/local/dovecot/etc/dovecot-sql.conf userdb: driver: prefetch userdb: driver: sql args: /usr/local/dovecot/etc/dovecot-sql.conf socket: type: listen master: path: /var/run/dovecot/auth-master mode: 384 user: vmail group: vmail plugin: quota: dict:::proxy:/var/run/dovecot/dict-server:quotadict dict: quotadict: mysql:/usr/local/dovecot/etc/dovecot-sql-dict-quota.conf Regards, Arvids

In running the various 1.0.n versions of Dovecot's LDA with the instructions in the wiki for using LDA with Postfix [on OS X 10.4] things went well using the instructions as-is (no setuid problems). This changed in moving over to the 1.1 beta. The LDA refused to work failing with the error "setgroups() failed: Operation not permitted" as I mentioned in a previous message. After reading the exchange between Bill Cole and Rich Winkel and following up on this, it seems that the new 1.1b wants you to give the Deliver app specific setuid permission via: cd /path/to/where/dovecot's/deliver/is sudo chmod u+s deliver Then things worked as before. There was no need to give the group 's' permission nor to change ownership of deliver from the default root:staff or root:wheel or whomever... . The error message seems odd though. I am not sure if, overall, this means there is a problem in Dovecot 1.0.n or that things are being tightened up in 1.1b. Thanks Bill and Rich for the tip! Jerry Yeager

I don't see this as a problem at all (why create one when there's none to be found:): * Move message into Spam: it's a spam that should be reclassified. * Move message out of Spam: it's a ham that should be reclassified. Don't really care where the mail comes from or where it is moved. This is the beauty of it all, count the key or mouse clicks, can't be less than this:) * Using the expire plugin, the Spam folder will be emptied auto- matically in due time (typically 30 days maybe) without user intervention. All close to zero maintenance for sysadmin as well as end-user. > Well, by now I dont have much, but I really would like to know how to > find the filename of a message being copied from a folder to another. No such luck (I think): to my understanding (with the help of Johannes in previous reply in this thread), you'd have to create a temporary file with the mail message using tmpnam() + mail_get_stream() or similar, and then do your thing. I'm aiming towards that exact functionality: I want to be able to do training using "pristine" source (so I'll need the whole message), and keep the previous functionality using signatures. We'll see how it goes. Good Luck and thanks for your input /Lars

[Dovecot] Configure/install path overrides
by Remy Zandwijk 30 Sep '07

30 Sep '07

Hi, I'm building and installing dovecot on a Solaris 10 machine and therefore I want to install Dovecot in /opt/dovecot. Thus, I start configure with --prefix=/opt/dovecot. I also override things like 'libexecdir', 'docdir', etc. When calling make install, Dovecot is installed in /opt/dovecot, but for example the binary user files are installed in /opt/dovecot/bin/dovecot. The same for the docs, which are installed in /opt/dovecot/share/doc/dovecot. I think that's not quite nice and neat, so I call 'make install' like: make docdir=/opt/dovecot/share/doc install. But even then, the wiki stuff is still installed in /opt/dovecot/share/doc/dovecot/wiki in stead of /opt/dovecot/share/doc/wiki. Very anoying. My point is that ./configure should be able to override all paths, but since some paths are somehow hard-coded in the Makefile, this is impossible. Any chance this will (be) change(d) sometime? -Remy

[Dovecot] deliver w/quotas - MDN after accept mail?
by Ken A 30 Sep '07

30 Sep '07

I'm testing deliver with sendmail and fs quotas. On an over quota condition, deliver accepts the mail, deletes it, then issues a MDN immediately. Is there a way to get deliver to soft fail like procmail does with a 400 error and queue the mail, then let sendmail handle the MDN, following it's "confTO_QUEUEWARN" and "confTO_QUEUERETURN" ? Thanks, Ken -- Ken Anderson Pacific.Net

[Dovecot] Testing sieve filter

28 Sep '07

Hi, I am trying to get sieve working with dovecot. Dovecot itself is working fine, and I have the following config: root@master:/var/log# dovecot --version 1.0.rc2 root@master:/var/log# dovecot -n # /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap ssl_disable: yes disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_extra_groups: mail default_mail_env: maildir:/var/mail/%u auth default: passdb: driver: pam userdb: driver: passwd I have this in my lda protocol: mail_plugins = cmusieve And I have created a .dovecot.sieve in both ~ and /var/mail/$user/ that looks like this: require "fileinto"; if exists "X-Spam-Flag" { fileinto "Junk"; } No mail gets moved to the junk folder, nut it does arrive in my inbox with the X-SPAM-Flag: Yes header. How do I troubleshoot this? I don't see anywhere in the logs any errors or any mention whatsoever of filtering activity or failure. I have seen numerous pages on how to set this up, but they invariably focus on setting up virtual users, which I do not need, so it isn't clear which steps I can safely ignore. thanks in advance, Cliff

[Dovecot] Documentation to create plugins.

28 Sep '07

hi! Is there any documentation to guide me how to create a dovecot plugin? I'm trying to read the code, but I'm not a good C programmer. I have been able to copy the mail-log plugin into copy-log, edited about 4 lines of code, then I edited Makefiles and configure, now I'm able to compile, install and use my "new" plugin. Anyway, any help is appreciated. Thankz! !DSPAM:46fd34b1153407177711712!

I have it (deliver) in a restricted access folder as a standard safety precaution, but as most of these "jails" end up being only safe for a short time I have again gone back to using Postfix as the deliver. Timo has from time to time mentioned that he was thinking that deliver needed to be rewritten. hmmm. I still give you and Rich credit though, if you had not mentioned the ideas behind Sendmail and LDA, it would most likely taken much longer before I read that wiki entry and gave that approach a try, instead of trying to find the missing setting for changing groups that the error message wants fixed. > -- > Bill Cole > bill(a)scconsult.com > > > > ------------------------------ > > Message: 7 > Date: Thu, 27 Sep 2007 17:07:28 -1000 (HST) > From: Julian Cowley <julian(a)lava.net> > Subject: [Dovecot] Dovecot raw backtrace when copying to folder > To: dovecot(a)dovecot.org > Message-ID: <alpine.LRH.0.9999.0709271646190.28814(a)taurus.cesta.com> > Content-Type: TEXT/PLAIN; format=flowed; charset=US-ASCII > > Seeing a problem with a certain user causing dovecot to crash when > copying > mail to a folder.

[Dovecot] dovecot IMAPS + kmail
by Timothy Murphy 27 Sep '07

27 Sep '07

I notice that kmail does not allow an IMAP sub-folder to be created (from an IMAPS client). When I try, kmail says this cannot be done for one of the following reasons: Your access permissions may be inadequate to perform the requested operation on this resource. The location where the folder was to be created may not exist. A protocol error or incompatibility may have occurred. Is there any simple way of getting round this? KMail has no problem creating top-level IMAP folders.

[Dovecot] filtering when mail is moved to IMAP Inbox
by Rahul Amaram 27 Sep '07

27 Sep '07

Hi, I have been looking for a solution to this problem for quite sometime but just haven't got any. This is how my current set up is. I have a IMAP Server installed on my home server. It has various folders. I have configured Thunderbird in my laptop to connect to the IMAP Server and access mails. I have also configured Thunderbird to download mails from my GMail account using POP3. I have set up a filter in Thunderbird to move all my mails which come to my Local Folders "Inbox" to my IMAP Server's Inbox. Now here is my question - Is it possible to set up some rules in the IMAP Server (maybe sieve) so that I can filter the messages coming to its Inbox and move them to another folder? The whole idea is that I have control over when I want to fetch mails from my GMail account but at the same time the filtering rules for moving to custom folders should be stored on the server so that i do not replicate this in every client. Regards, Rahul. -- http://rahul.amaram.name

[Dovecot] blackberry with imap idle and concurrent connections
by Chris Tirpak 26 Sep '07

26 Sep '07

Hello - I've combed the wiki and archives a bit and can't seem to find what I am lookng for. It seems that BlackBerry Internet server has an issue with IMAP accounts along with IDLE and concurrent connections. Please see the following link (sorry it's fairly long): http://www.blackberry.com/btsc/search.do?cmd=displayKC&docType=kc&externalI… It appears as though IDLE can be implemented without "concurrent connections". Courier appears to do this although they have an option to turn it on. At first blush it seems obvious that any mail server will permit concurrent connections but as I read the docs for Courier and BlackBerry it appears to be a subtle thing whereby IDLE allows more than one connection to IDLE against the same IMAP folder when using maildir. Does Dovecot support his? Also, if anyone on the list has experience running a BlackBerry against Dovecot, are you currently getting instant (or near instant) notifications? If so what service are you using? T-Mobile? I am considering upgrading and using Dovecot but BlackBerry support has become critical. Thanks in advance. Chris

[Dovecot] Moving email from a folder to another using IMAP is very slow (sometimes)
by Stefano Scalise 26 Sep '07

26 Sep '07

Hi to all, I am using the new beta release 1.1. I am experiencing, after the upgrade to the 1.1beta some problems regarding the following scenario: I am conneted with Outlook to dovecot server using IMAP. I have many folders and I want to move an email from a folder to another using drag and drop. I see that when I move the email, the IMAP process goes to 90-95% for about 5 seconds and after, the mail is finally moved. I noticed that this operation sometimes (20% about) is again fast. There is no problem of overload of the server because this mail server, at the moment, manage just 1 email address. Before the upgrade to 1.1beta, this operation was very very fast. Is there a way to try to debug the IMAP process for understanding what is happening? Thank you for your help. Stefano.

But a few days ago some coworkers mentioned that they got errormessages in their Mailapp. I searched in the logfiles and found this: Sep 14 12:07:35 Mailserv dovecot: IMAP(eckhard-ma-domain-com): fsync(/home/eckhard-ma-domain-com/mails/.INBOX.0002-Druckangebote von Druckereien.0002-schmerk zwei_E-Mailverkehr/tmp/1189764455.P15962Q0M486676.Mailserv) failed: Input/output error Sep 14 12:07:46 Mailserv dovecot: IMAP(eckhard-ma-domain-com): fsync(/home/eckhard-ma-domain-com/mails/.INBOX.0002-Druckangebote von Druckereien.0002-schmerk zwei_E-Mailverkehr/tmp/1189764466.P15962Q1.Mailserv) failed: Input/output error Mailserv:~# cat /var/log/mail.log.* | grep fsync Sep 20 16:08:40 Mailserv dovecot: IMAP(aicher-fre-domain-com): fsync(/home/aicher-fre-domain-com/mails/.Sent/tmp/1190297319.P5290Q0M979653.Mailserv) failed: Input/output error Sep 20 16:08:48 Mailserv dovecot: IMAP(aicher-fre-domain-com): fsync(/home/aicher-fre-domain-com/mails/.Sent/tmp/1190297328.P5290Q1.Mailserv) failed: Input/output error Sep 20 16:18:24 Mailserv dovecot: IMAP(aicher-fre-domain-com): fsync(/home/aicher-fre-domain-com/mails/.Sent/tmp/1190297904.P5290Q3.Mailserv) failed: Input/output error Sep 20 16:23:20 Mailserv dovecot: IMAP(aicher-fre-domain-com): fsync(/home/aicher-fre-domain-com/mails/.Sent/tmp/1190298200.P5290Q6.Mailserv) failed: Input/output error The /home/ dirs are at a simple RAID 1 System, ext2 filesystem. No NFS or other networkstuff. I'm on a Debian Etch with dovecot 1.0.rc15-2 Any hints what this can be? Thank you in advance Hermann Wacker

[Dovecot] deliver net_connect auth-master failed: Permission denied

Ok, I've ALMOST got this working ... I can run deliver as a user, but when I try using it as the default delivery agent from sendmail, I get deliver(userid): net_connect(/var/run/dovecot/auth-master) failed: Permission denied Does deliver run as root, as the recipient's ID, sendmail's ID or sendmail's GID?

[Dovecot] Password auth with Postfixadmin & MySQL
by James Dehnert 25 Sep '07

25 Sep '07

I am trying to get Postfix, Dovecot, Postfixadmin, and MySQP all working together. I'm using 1.0.5 atm. I've hit a point where I can't seem top get dovecot to auth to the MySQL password database It seems to see the user OK, but I can't seem to get a password match. MySQL has password stored as MD5, as per Postfixadmin. When I add plain-md5 to the auth mechanisms dovecot seems to use plain and fails.

[Dovecot] user_global_uid and user_global_gid
by Stefano Scalise 25 Sep '07

25 Sep '07

Hi to all, I am using the new beta release 1.1. I see that parameters user_global_uid and user_global_gid are no more used in dovecot-ldap.conf. That means that, as I use LDAP as backend I am obliged to se t these two fileds in LDAP for each user even if they are always the same, as I use virtual domains. I see that I can set the in dovecot.conf the parameters mail_uid and mail_gid, but even if I set these parameters, when I do the query in LDAP (for retrieving other useful parameters) I have the error: userdb(<email address>) didn't return uid but... I don't want to take uid parameter from LDAP, I want to set it globally but I still want to do an LDAP query. Is there a way to do this in the new evrsion or I cannot do anymore this? Thank you, Stefano.

[Dovecot] v1.1.beta1 released
by Timo Sirainen 25 Sep '07

25 Sep '07

http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta1.tar.gz http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta1.tar.gz.sig Alpha6 seemed to finally work quite well, so I think it's time for a feature freeze (except for dbox changes). I started a new wiki page to list incompatibilities between v1.0 and v1.1: http://wiki.dovecot.org/Upgrading/1.1 Fixes since alpha6: - deliver + maildir caused "UID 0 in transaction log" errors - deliver + maildir no longer blocks if dovecot-uidlist.lock file exists. The mail is simply delivered without updating uidlist or indexes. - Quota handling fixes, especially dict quota - etc.

[Dovecot] pam session=yes with gssapi authentication
by Thomas Mueller 25 Sep '07

25 Sep '07

hi there I noticed the following behaviour with auth backend pam and "args session=yes *" configuration: - login with "plain": pam session gets opend - login with "gssapi" (kerberos): pam session isn't opend (-> no $HOME will be created) Is this a bug or just a limitation by GSSAPI (maybe gssapi works around PAM)? - Thomas Dovecot Versions seen this: - 1.0.rc15 (Debian 4.0 Etch) - 1.0.0 (Debian backports)

I find the statement that dovecot has maildir format support misleading. By maildir support, I mean that mail is contained in directories ~/Maildir/inbox/[cur,new,tmp], ~/Maildir/Family/[cur.new.tmp], ~/Maildir/Finance/[cur,new,tmp], etc. This is the setup created if one runs kmail as mail client, specifying that one is using maildir format, and using the GUI to create new folders Family, Finance, etc. As far as I can see, if you now set up an IMAP server using dovecot on this machine, setting mail_location = maildir:~/Maildir/ in /etc/dovecot.conf then the email in the folders Family, Finance, etc will not be seen by an IMAP client. > But as soon as you have an e-mail klant using a non-supported mailbox > format *or* that is storing mail folders in a supported format but in > a non-standard place, tour theory applies, yes. What is the "standard" place for mail folders? > See also <http://wiki.dovecot.org/> for more info about this all. I've studied that wiki, and not found clear information on this point. To clarify my question, suppose one has email organised in server X as described above, in directories ~/Maildir/Family/[cur.new.tmp/ , etc. And now suppose one wants to access this email from laptop Y. How exactly does one have to change the setup on machine X? And what does one set mail_location to? It seems to me that this is an issue likely to be faced by anyone wanting to run a small home network. reading email on various machines, and wanting this email to be kept "in sync". Maybe dovecot is not a suitable program for this purpose?

[Dovecot] 1.1 Beta 1 Works!
by Luciano Mannucci 25 Sep '07

25 Sep '07

Wow! I'm running 1.1 Beta 1 on OpenSuSE linux 10.2. It seems not bad at all. The only thing I've not quite well understood is this message, that pops up when I start dovecot: Warning: fd limit 1024 is lower than what Dovecot can use under full load (more than 1536). Either grow the limit or change login_max_processes_count and max_mail_processes settings Where does dovecot take this 1024 fd limit? My machine-wise limit is some orders of magnitude bigger, af far as I can tell by reading /proc/sys/fs/file-max... luciano. -- /"\ /Via A.

[Dovecot] Deliver, sendmail & envelope From_
by Rich Winkel 25 Sep '07

25 Sep '07

Sorry, couldn't find this in the archives. Under freebsd 4.x, the native mail.local that sendmail uses by default writes From_ lines that include the origin address. This is very readily parsable and handy for quick greps in mboxes. But deliver defaults it to MAILER-DAEMON. I see you can specify the envelope From_ with "-f", but I'm not sure how that's useful. Also I'm trying to figure out the instructions for making deliver the default delivery program under sendmail. This is a very plain vanilla setup I have here, procmail is not configured into sendmail.cf so I'm not sure how to adapt the instructions at wiki.dovecot.org/LDA/Sendmail Any help would be much appreciated. I've appended my local mailer stuff below. Should I just substitute deliver's path for mail.local? By the way, dovecot is very slick! It should speed up my mail server by a huge factor. Many thanks to Timo!

[Dovecot] Unknown dict module: db
by Lars Stavholm 24 Sep '07

24 Sep '07

Using dovecot-1.1beta1 I get "Unknown dict module: db" when starting up dovecot. In dovecot.conf I've got the "expire_dict = db:/var/lib/dovecot/expire.db" statement in the plugin{} section. Aparently required when the "expire" plugin is enabled. dovecot is built with "--with-db" and db-devel is present at compile time. Any ideas anyone? Cheers /Lars

[Dovecot] deliver copies "^From " header lines when delivering to Maildir
by pod 24 Sep '07

24 Sep '07

deliver appears to copy "^From " header lines from stdin when delivering to Maildir. The header filtering in mbox-save.c prevents this when delivering to an mbox and instead a synthesized "^From " header is written. This is an issue when using, for example, Postfix and mailbox_command = /usr/libexec/dovecot/deliver which does not appear to have an option not to write a "^From " header on the mailbox_command input. I'm attaching a patch that adds a save_header_callback() along the same lines as in mbox-save.c but I'm really not sure this is the right way to do it.
