[Dovecot] Missing TMP folder - Dovecot 1.2 Beta3
by Matt Rude 26 Mar '09

26 Mar '09

Recently after upgrading to 1.2 Beta3 from 1.1.13, I started to defer mail. After looking into it deeper, it looks like Dovecot/sieve now asks for a tmp folder in the imap (maildir) folder. Once I added the tmp folder as the logs indicants, the mail was processed normally. I have split my Inbox and imap store to different folder. Looking at what it's trying to do, it looks to me that dovecot/sieve expect the imap directory to be the Inbox. Is this a bug, or intended behaver? # Log output, when requeueing the message in postfix, with mail_debug on ######################################################################### Mar 24 12:02:50 samantha postfix/qmgr[6855]: EB4141237BD: from=<colleen(a)example.com>, size=493284, nrcpt=1 (queue active) Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): Loading modules from directory: /usr/local/lib/dovecot/lda Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): Module loaded: /usr/local/lib/dovecot/lda/lib10_quota_plugin.so Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): Module loaded: /usr/local/lib/dovecot/lda/lib20_expire_plugin.so Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): Module loaded: /usr/local/lib/dovecot/lda/lib90_cmusieve_plugin.so Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): auth input: maildir=example.com/jill@example.com/ Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): auth input: uid=1000 Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): auth input: gid=1000 Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): auth input: quota_rule=*:storage=524288 Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): Quota root: name=User quota backend=maildir args= Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): Quota rule: root=User quota mailbox=* bytes=536870912 messages=0 Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): Quota rule: root=User quota mailbox=Trash bytes=53687091 (10%) messages=0 Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): Quota rule: root=User quota mailbox=Junk bytes=107374182 (20%) messages=0 Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): maildir: data=/var/spool/virtualmailboxes/example.com/jill@example.com/imap/:INBOX=/… Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): maildir++: root=/var/spool/virtualmailboxes/example.com/jill@example.com/imap, index=/var/spool/virtualmailboxes/Indexes/example.com/jill@example.com, control=, inbox=/var/spool/virtualmailboxes/example.com/jill@example.com Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): cmusieve: /var/spool/virtualmailboxes/example.com/jill(a)example.com/dovecot.sieve doesn't exist Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): cmusieve: Using sieve path: /var/spool/sieve/dovecot.sieve Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): cmusieve: Executing script /var/spool/sieve/dovecot.sievec Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): Namespace : Using permissions from /var/spool/virtualmailboxes/example.com/jill(a)example.com/imap: mode=0700 gid=-1 ****** Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): creat(/var/spool/virtualmailboxes/example.com/jill@example.com/imap/tmp/tem… failed: No such file or directory ****** Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): copy: i_stream_read() failed: No such file or directory Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): msgid=<85866319ca18bf9cd994e34fe806c4f5.squirrel(a)mail.mattrude.com>: save failed to INBOX: Internal error occurred.

I use dovecot mailbox as destination of fetches from a few POP mailboxes. I would like to pass name of "source mailbox" to sieve script via deliver's command line option(s).

[Dovecot] Dbox Upgrade Problem With MAILBOXDIR
by Alan Swanson 25 Mar '09

25 Mar '09

Hi. Trying to upgrade from Dovecot 1.1.11 to 1.1.13 but having a problem with imap process segfaulting. Backtrace is below. I presume it's related to these MAILBOXDIR changes but the only documentation is the single line in the news for changing to ":MAILBOXDIR=mailboxes" when using dbox. Current configuration is "mail_location = dbox:~/Mail" so what exactly should be changed here?

[Dovecot] selection correct auth with multiple auth methods
by jm 25 Mar '09

25 Mar '09

How do you control which socket or authentication process dovecot's pop3 daemon chooses to use? I've got a user database with two flags one to allow pop3 access and the other to allow the use of auth smtp. There are two authentication instances configed, thus, auth default { .... passdb sql { args = /etc/dovecot-sql-postfix.conf } .... socket listen { master { path = /var/run/dovecot/auth-master mode = 0660 user = group = } } auth postfix { ..... passdb sql { args = /etc/dovecot-sql-postfix.conf } .... socket listen { client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } } From the logs and testing pop3 is using the postfix authentication instance and not the default as expected. Does anyone out there know how control dovecot's pops daemon authentication choice? This infomation seems to be lacking in the documentation I can find. Jeff.

[Dovecot] Making changes to dovecot log levels
by Thomas M Goerger 24 Mar '09

24 Mar '09

Hi Timo, Awhile back I'd written about making changes to some of the log levels that dovecot writes to to stop the process from writing these to monitor. I wanted to run a few changes by you for this, just to make sure these won't cause problems somewhere else. And to send this to the list, in case anyone else wants to make similar changes in the future. In the file src/lib-index/mail-index.c: duplicate the function mail_index_set_error to mail_index_set_warning and call this function in /src/lib-index/mail_cache.c instead int mail_index_set_error(struct mail_index *index, const char *fmt, ...) { va_list va; i_free(index->error); if (fmt == NULL) index->error = NULL; else { va_start(va, fmt); index->error = i_strdup_vprintf(fmt, va); va_end(va); i_error("%s", index->error); } return -1; } changing the line : i_error("%s", index->error); to i_warning("%s", index_error); and for the file src/lib-storage/index/mbox/mbox-sync.c changing this code if (rec == NULL && uid < sync_ctx->idx_next_uid) { /* this UID was already in index and it was expunged */ mbox_sync_set_critical(sync_ctx, "mbox sync: Expunged message reappeared in mailbox %s " "(UID %u < %u, seq=%u, idx_msgs=%u)", sync_ctx->mbox->path, uid, sync_ctx->idx_next_uid, sync_ctx->seq, messages_count); ret = FALSE; rec = NULL; } else if (rec != NULL && rec->uid != uid) { /* new UID in the middle of the mailbox - shouldn't happen */ mbox_sync_set_critical(sync_ctx, "mbox sync: UID inserted in the middle of mailbox %s " "(%u > %u, seq=%u, idx_msgs=%u)",sync_ctx->mbox->path, rec->uid, uid, sync_ctx->seq, messages_count); ret = FALSE; rec = NULL; from mbox_sync_set_critical( etc... to mail_storage_clear_error(storage) i_warning("Error text"... mail_storage_set_internal_error(storage) to clear and set the storage pointer Hopefully that's all clear. If you have any questions, please let me know.

[Dovecot] Problem with dovecot + imap idle + qmail-local delivery
by Jochen Schug 24 Mar '09

24 Mar '09

Hi, I've recently switched from courier-imap to dovecot. Everything seemed to work fine, but after I while I noticed that dovecot is occasionaly causing problems with delivery of new incoming mails. System: Gentoo Linux, kernel 2.6.19, qmail 1.03, vpopmail 5.4.26 , dovecot 1.1.11, maildir, mail store on ext3. Symptoms: qmail is having trouble with the mail delivery. First I thought it had something to do with vpopmail or dovecot's quota support, but I tracked it down to qmail-local. I tried two different versions, one with Bill Shupp's maildir++ patch and one without. With the patch, I'm getting "User_over_quota._(#5.1.1)" errors. Mail is delivered once and sender is sent a notification about the exceeded quota. Without the patch, I get "Temporary_error_on_maildir_delivery._(#4.3.0)". Mail is delivered, but delivery is tried again and again. This only happens if a MUA is logged in to the mailbox and IMAP IDLE is being used. If the MUA is disconnected: fine. If dovecot is stopped: fine. I tried a couple of different things, all without success: - upgraded dovecot from 1.1.7 to 1.1.11 - compiled a new kernel with inotify support and recompiled dovecot - migrated mail store from reiserfs to ext3 - disabling quota support in dovecot - tried dovecot's various file locking mechanisms Right now I'm working around this by removing IDLE from the capabilities. This solves the problem, but leaves me with a less functional IMAP server. Any help is greatly appreciated.

[Dovecot] Staged migration from mbox to maildir
by Stewart Dean 24 Mar '09

24 Mar '09

So much changes in this migration that the ideal way to do it would be to begin with a few users or a department, then migrate the users affinity group by affinity group: first an institute or so, then the faculty, then the staff, then the students, moving to bigger and bigger groupings as the bugs work out of the migration and the move becomes more assured. We use sendmail and procmail. There's no problem there, as the ~./procmailrc can be changed to over-ride the mbox default until all groups are done and it become the default. The problem comes with IMAP. While dovecot can tell if a folder is mbox or maildir, it has to be pointed to the right place (by namespace definitions in the client, IIRC), and the default of putting the inbox under ~/mail is one I'd like to embrace for various reason...but given that that means moved inbox folders and *that* means either making a global change (there goes staged migration) OR changing the namespace definitions on each PC. I can get to the early few and change the namespaces definition, but there doesn't appear to any equivalent (enlighten me, if I'm missing something) to ~/.procmailrc for imap, so that I don't have to get on the client machine. Is this correct or am I (hopefully) wrong and there *is* a way to change things on the server that allows for staged migration? Oh, I would so like to be wrong!

[Dovecot] dovecot with IMAP and POP3 mixed

[Dovecot] Released Sieve v0.1.4
by Stephan Bosch 23 Mar '09

23 Mar '09

Hello Dovecot users, Not much Sieve development was done in the last five weeks, but some important platform-dependent bugs were found and repaired. The main new feature is the addition of a custom Sieve language extension for debugging in the Sieve command line tools. Changelog Sieve v0.1.4: * Started work on the sieve-filter tool. With this command line tool it will be possible to (re-)apply Sieve filters on a mail folder. It is currently undocumented and far from functional. + Added a custom debug extension that provides the possibility to print debug messages from scripts executed by the Sieve tools. - Fixed issue with opening relative paths as a mail file. Bug reported by Ian P. Christian. - Fixed MAC OSX compile problem. Turns out the extern modifier was missing at multiple places. Bug reported by Edgar Fuss. - Fixed Solaris compile problem: removed unecessary and unportable linker flags that caused compile to fail. Bug reported by Andres Yacopino. The release is available as follows: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.4.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.4.tar.gz.sig Have fun testing the new release and don't hesitate to notify me when there are problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

[Dovecot] v1.1.13 and v1.2.beta3 released

http://dovecot.org/releases/1.1/dovecot-1.1.13.tar.gz http://dovecot.org/releases/1.1/dovecot-1.1.13.tar.gz.sig http://dovecot.org/releases/1.2/beta/dovecot-1.2.beta3.tar.gz http://dovecot.org/releases/1.2/beta/dovecot-1.2.beta3.tar.gz.sig Looks like Friday the 13th isn't the best day to make releases. :) These releases fix two bad bugs in v1.1.12. - v1.1.12's MAILBOXDIR changes broke accessing mails in some setups - v1.1.12's login_executable -D checking changes caused dovecot to crash at startup if protocols setting contained only pop3. - mbox: pop3_lock_session=yes was broken with mail_privileged_group.

[Dovecot] Single Instance Storage still on the roadmap?
by Charles Marcus 20 Mar '09

20 Mar '09

Hey Timo, I was curious where Single Instance Storage fits in on the roadmap, now that you are maybe settled in in your new digs... Is it still coming soon? Has it been pushed back by your new employers priorities? Its real high on mine, so if has been back-burnered, I'll need to start looking for alternatives... Thanks, -- Best regards, Charles

[Dovecot] update of current quota usage
by floss＠pBartels.info 20 Mar '09

20 Mar '09

Hello, I use Dovecot 1.1.11 and store the current quota usage in a Database. As far I can see it, the quota usage is updated each time dovecot performs an action on a mail. For example if a new mail is stored in the inbox, the current quota usage is increased. If a mail is deleted the quota usage is decreased. If there are still existing E-Mails in the inbox, before quota is turned on or if I perfom changes on the "mail storage" myself (for example purging trash or spam, or something) the current quota usage is NOT updated automatically by dovecot. For example I copy some mailboxes to my server, then the current quota for this mailboxes is still zero. Is it correct that dovecot can't do this for me? If yes, it seems I have to write my own (simple) update script and run it sometimes croned (because I don't really trust the actual quota implementation) and/or I have to update the current quota usage each time I perform actions myself. This "workaround" is easy by using a DB storage, but what about other implementations? Wouldn't it be nice if dovecot could do this or provide a tool for it? Thank you! Philipp

[Dovecot] ESORT broken in Dovecot 1.2

Looks like ESORT is broken (just compiled 1.2 from hg 10 minutes ago). Here is the command I'm using and the corresponding error message: C: 5 UID SORT RETURN (ALL COUNT) (ARRIVAL) US-ASCII UNSEEN S: 5 BAD Error in IMAP command UID: Invalid sort argument. The corresponding UID SORT command (without the RETURN syntax) works fine: 5 UID SORT (ARRIVAL) US-ASCII UNSEEN * SORT 5 OK Sort completed (0.000 secs). michael

[Dovecot] fchown() error with Public Folders

I was able to get public folders to work with a dedicated account for the hierarchy and ACL's for individual users. I have location defined so that each user has a local index and control files location = maildir:/usr/mail/public/cs/mail:CONTROL=~/Maildir/CS:INDEX=~/Maildir/CS Now i am seeing the folliwing error in the logs. dovecot: IMAP(stephen): fchown() failed with file /home/stephen/Maildir/CS/.Incoming/dovecot.index.log: Operation not permitted As I understand it, dovecot runs as root but the the IMAP process that servicers the request runs as the user so naturally the fchown() fails.

[Dovecot] IMAP ACLs not working
by Seba 18 Mar '09

18 Mar '09

Hi, I've some problems to get folder ACLs working with Dovecot. I've defined some folders (like drafts, spam etc.) for every user and created a dovecot-acl file in every folder so that users can not delete or rename these folders but this does not work as expected. Config ===== Debian Lenny 5.0 Dovecot 1.0.15 dovecot.conf ========= protocols = imap protocol imap { listen = xxx.xxx.xxx.xxx } disable_plaintext_auth = yes log_timestamp = "%Y-%m-%d %H:%M:%S " ssl_disable = yes mail_location = maildir:/home/vmail/%Ld/%Ln namespace private { separator = . prefix = inbox = yes } mail_privileged_group = vmail protocol imap { mail_plugins = acl } protocol lda { postmaster_address = postmaster(a)example.com hostname = hostname(a)example.com mail_plugins = cmusieve } auth_username_translation = %Lu auth default { mechanisms = cram-md5 passdb pam { } passdb sql { args = /etc/dovecot/dovecot-sql.conf } userdb passwd { } userdb static { args = uid=5000 gid=5000 home=/home/vmail/%d/%n allow_all_users=yes } user = root socket listen { master { path = /var/run/dovecot/auth-master mode = 0600 user = vmail } client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } } Folder structure =========== (For dovecot-acl) /home/vmail/example.com/user/.Spam/dovecot-acl dovecot-acl contains =============== owner lrwstiek For me the config looks OK and I can't find an error... When I change the dovecot-acl to "owner l" for example it seems that this change has no effect. Are there an error in my setup? Seba

[Dovecot] mbox on NFS + automount, folder creation -> mkdir_parents() failed
by Sebastian Kayser 18 Mar '09

18 Mar '09

Hi, i am about to migrate some internal imapd mboxes to dovecot. Regular access is fine, just when i want to create a folder i get the following error message in the logs: Mar 18 17:36:57 pulsar dovecot: [ID 107833 mail.error] IMAP(skayser): mkdir_parents(/home/skayser) failed: Operation not applicable /home/skayser is mounted via autofs. When i set mail_location to a subdirectory within /home/skayser, folder creation works. From looking at the truss output dovecot tries to mkdir() the parent and doesn't seem to like the ENOSYS that is returned when the directoy is an autofs mountpoint.

Uhg, I win the CluelessnUnobservant Award for this. Thanks everyone for the followups. I caught that myself yesterday and fixed the problem on Postfix's side. To sum up in case anyone else runs in to this, the mistake I made was in assuming that Postfix just made the handoff to Dovecot and that Dovecot would handle the rest, so I commented out the parts of the old config where Postfix handled this when I was using Postfix virtual transport. Once I restored those and gave Postfix the query it needed, it worked fine. Thanks for bearing with me, everyone. Kat

Re: [Dovecot] Dovecot LDA and "undeliverable" emails

Timo wrote: > So Postfix delivers bounces to everyone by calling Dovecot LDA > separately for each bounce? Looks like a Postfix configuration problem > to me. I should have been more specific... because we'd also changed domain names at the time we moved over to using Dovecot as the LDA, I temporarily disabled automatically bouncing mail addressed to invalid users because I figured that we'd have at least one who decided that they didn't want the standard formation of email addresses... What I'd wanted to happen was for Postfix to accept the message(s) and then for them to be delivered to the postmaster address so that I could address the issue. I'm still unsure as to why, when Dovecot couldn't find the user in the tables, it copied the message to every user of the system - that seems like odd behavior, which indicates that even though the system is "working", I need to fine-tune something. And at Charles request, here's the output of dovecot -n: # 1.0.10: /etc/dovecot/dovecot.conf base_dir: /var/run/dovecot/ log_path: /var/log/dovecot info_log_path: /var/log.dovecot.info protocols: imap imaps pop3 pop3s disable_plaintext_auth: no 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 login_greeting: Dovecot ready login_process_per_connection: no valid_chroot_dirs: /var/spool/mail max_mail_processes: 2048 mail_location: maildir:/home/vmail/%d/%n mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_process_size: 1024 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 imap_client_workarounds: delay-newmail outlook-idle netscape-eoh pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv pop3_client_workarounds: outlook-no-nuls oe-ns-eoh namespace: type: private separator: . prefix: INBOX. inbox: yes auth default_with_listener: mechanisms: plain login verbose: yes debug: yes passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: static args: uid=5000 gid=5000 home=/home/vmail/%d/%n allow_all_users=yes socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: vmail

[Dovecot] Dovecot as a POP3-/POP3SSL-proxy in front of exchange 2003
by south africa 17 Mar '09

17 Mar '09

Dear all, im looking for a solution to protect an Exchange 2003 email server from direct "pop3-internet-connects". Is it possible that Dovecot act as a POP3-/POP3SSL-Proxy, "LDAP-authenticate" all user logins to a Windows 2003 domain controller and forward then all POP3-connects to a single Exchange 2003 server? Could someone give me some advices or a link for howtos for this solution? The howto on www.dovcot.org (http://wiki.dovecot.org/HowTo/ImapProxy) does not fit in my situation because it prefere a mysql server and not a LDAP-server/domain-controller.

[Dovecot] Errors on mbox to Maildir conversion
by Phill Edwards 17 Mar '09

17 Mar '09

I have Julian Fitzell's migrateuser.sh script which uses mb2md-3.20.pl to convert a mailbox in mbox format to Maildir. I have set up a test user called "mailtest" which has mail as follows: /var/mail/mailtest /home/mailtest/mail/ Drafts MoreStuff Sent Items Stuff After the conversion I want all this user's mail to be in /home/mailtest/Maildir/ I'm not quite sure how to run the migrateuser.sh script, but I think it's like this (run as user mailtest): $ /usr/local/bin/mb2md/migrateuser.sh mailtest /home/mailtest /home/mailtest/Maildir When I run this I get the following output: mailtest -- Migrating INBOX...

[Dovecot] folders are not under INBOX
by Ondrej Svoboda 16 Mar '09

16 Mar '09

hi guys, I hope it's common trouble, but I'm not able to find a solution: - i'am using courier imap and trying to migrate to the dovecot - on courier I have all folders as subfolder of Inbox - i.e. Inbox.Sent but on dovecot the folder Sent is not subfolder of Inbox, but its on the same level. Please is there some possibility to have the subfolders the same behaviour as in courier? we have lot's of customers so after the upgrade the folders can't change. thank you ondrej

[Dovecot] Dovecot and high availability
by d dimov 16 Mar '09

16 Mar '09

Hello dear all. Please accept apologies if the topic was discussed already, tried searching the archives but found few details. What I am looking for would be the best way to making Dovecot highly available in an environment where: two Alteons are load-balancing two Dovecot servers, each Alteon seing both of them; the clients are using exclusively POP3; low volume; in case of a Dovecot server failure service should fail over to the other node with preferably no manual intervention. Failover could mean Alteons just ignoring the failed host and routing all requests to the healthy one. Would it be shared NFS volume mounted on both of the servers from some NAS, maildirs put on that volume and both Dovecots seing the mailboxes simultaneously? Any risks? Is there a good document describing such a setup? Thank you in advance and please indicate if I missed relevant details. Best regards, Dimov

The only symptom is the log messages. The client sees nothing unusual, at least in this case where the session is a retrieval of one large message. I haven't tried long sessions retrieving multiple messages. If I remove pop3_lock_session = yes, the issue does not occur. I don't think I need it. I put it in a long time ago to attempt to solve a problem that was actually caused by something else. Since removing it does seem to avoid this issue, I will leave it out, but I'm reporting this anyway as it seems there may be some underlying problem. -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.

[Dovecot] pop-proxy to redundant servers ?
by Jan-Frode Myklebust 15 Mar '09

15 Mar '09

I'm considering putting two servers with failover IP-addresses in front of our pop/imap cluster, with dovecot in proxy-mode running on both servers. But, can dovecot handle more than one backend server for each user ? I.e. I would want to point the dovecot proxy to send userX to backend-server1, or backend-server2 if backend-server1 is down. Is something like that possible ? -jf

Changes in v1.2.beta2 since beta1: * Authentication userdb: Renamed system_user to system_groups_user. Probably pretty much no one used this feature. * deliver no longer creates temp files to /tmp. They're instead created to the users' mailbox directories. - IMAP: Fixed SORT command crashing - POP3 was broken in beta1 - Fixes to virtual mailboxes - Fixes to IMAP ACL support Changes in both v1.1.12 and v1.2.beta2: * Added :MAILBOXDIR= to mail_location to specify the root dir for mailboxes. dbox users should migrate to ":MAILBOXDIR=mailboxes", because that's going to be the default in v1.2+. + Linux: Adding -D parameter to login_executable makes login processes dump core to login_dir if they crash. - IMAP: SELECT didn't always return first unseen message in reply - POP3: pop3_lock_session=yes didn't use mail_privileged_group while dotlocking. - mbox: Don't crash if >=8192 bytes long line begins with "From ". - Maildir: More fixes to handling over 26 keywords. - Several logging fixes and improvements - Fixed authentication caching with non-plaintext mechanisms when using a blocking passdb (e.g. MySQL) - Fixed DIGEST-MD5 authentication with user@domain style usernames.

[Dovecot] setting up both system password users AND virtual users
by Jim Pazarena 14 Mar '09

14 Mar '09

I'm afraid that I am a rookie at dovecot, and cannot seem to figure the configuration for a dual system & virtual setup. For now I am using POP3 ---only--- I've got the "system" working, but cannot figure out how to add the virtual system. The docs aren't quite clear enough for me to understand. The wiki example for dynamic passwd-file locations shows: mail_location = maildir:/home/%d/%n/Maildir userdb passwd-file etc etc I am using mbox, not maildir, AND I've already used mail_location for my system accounts with the following line: mail_location = mbox:~/mail/:INBOX=/mail/%u In the case of my virtual users, the mail is stored in INBOX=/mail/VIRTUAL/%d/%u and the password file is stored in /exim/etc/VIRTUAL/%d/passwd would someone kindly help me with this? thanks!

[Dovecot] pam_authenticate() failed: authentication error
by Zbigniew Szalbot 14 Mar '09

Hello, I would like to ask for your help. I have noticed some error messages issued by dovecot. Mar 13 20:00:57 relay dovecot: auth-worker(default): pam(example(a)example.com): pam_authenticate() failed: authentication error (/etc/pam.d/dovecot missing?) Not surprisingly $ l /etc/pam.d/dovecot ls: /etc/pam.d/dovecot: No such file or directory The funny thing is that authentication does work but I guess I have something misconfigured. I'd appreciate if you could help me. I am on a FreeBSD system (7.0) if that matters. Thank you! -- Zbigniew Szalbot

Hi, all. I use dovecot-1.1.11 with OpenLDAP backend. but i found the mail_location is not correct. How can i override mail_location setting in dovecot.conf? LDAP user data and dovecot config are attached below. in dovecot config, mail_location is: ---- mail_location = maildir:/%Lh/%Ld/%Ln/:INDEX=/%Lh/%Ld/%Ln/ ---- but the correct maildir should be 'homeDirectory' + 'mailMessageStore': ---- maildir:/home/vmail/a.cn/w/ww/www/ ---- LDAP user: ---- dn: mail=www(a)a.cn,ou=Users,domainName=a.cn,o=domains,dc=iredmail,dc=org objectClass: inetOrgPerson objectClass: mailUser objectClass: top cn: www sn: www uid: www mail: www(a)a.cn accountStatus: active homeDirectory: /home/vmail mailQuota: 104857600 userPassword: {SSHA}crkYO5tg8KRkOY7W3bRgjtLQ+79U4NgG enabledService: mail enabledService: smtp enabledService: pop3 enabledService: imap enabledService: deliver mailMessageStore: a.cn/w/ww/www/ ---- Dovecot ldap config file: ---- user_attrs = homeDirectory=home,=sieve_dir=/home/vmail/sieve/%Ld/%Ln/,mailMessageStore=maildir:mail,mailQuota=quota_rule=*:bytes=%$ ---- Dovecot main config file: ---- # dovecot -n # 1.1.11: /etc/dovecot.conf # OS: Linux 2.6.18-128.el5 x86_64 Red Hat Enterprise Linux Server release 5.3 (Tikanga) log_path: /var/log/dovecot.log protocols: pop3 pop3s imap imaps listen: * ssl_cert_file: /etc/pki/iRedMail/SSL_Cert.pem ssl_key_file: /etc/pki/iRedMail/SSL_Key.pem 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_uid: 500 mail_gid: 500 mail_location: maildir:/%Lh/%Ld/%Ln/:INDEX=/%Lh/%Ld/%Ln/ mail_debug: yes mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugins(default): quota imap_quota zlib mail_plugins(imap): quota imap_quota zlib mail_plugins(pop3): quota zlib mail_plugin_dir(default): /usr/lib64/dovecot/imap mail_plugin_dir(imap): /usr/lib64/dovecot/imap mail_plugin_dir(pop3): /usr/lib64/dovecot/pop3 pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain login default_realm: a.cn user: vmail passdb: driver: ldap args: /etc/dovecot-ldap.conf userdb: driver: ldap args: /etc/dovecot-ldap.conf socket: type: listen client: path: /var/spool/postfix/dovecot-auth mode: 438 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 438 user: vmail group: vmail plugin: quota: maildir quota_rule: *:storage=10M expire: Trash 7 Trash/* 7 Junk 30 expire_dict: proxy::expire auth_socket_path: /var/run/dovecot/auth-master sieve: /home/vmail/sieve/%Ld/%Ln/.dovecot.sieve dict: expire: db:/var/lib/dovecot/expire/expire.db ---- -- Best regards.
