[Dovecot] uint_cmp bug
by Mike Abbott 26 Jan '09

26 Jan '09

In reviewing the differences between 1.1.8 and 1.1.9 I saw a probable bug in the new function uint_cmp() in src/lib-storage/index/maildir/ maildir-sync-index.c: if (*i1 < *i2) return -1; else if (*i1 > *i2) return -1; else return 0; The second case should return 1 not -1.

[Dovecot] Released ManageSieve v0.10.5 for Dovecot v1.1.9
by Stephan Bosch 26 Jan '09

26 Jan '09

Hello Dovecot users, Because there was a crash bug in the ManageSieve v0.10.4 login daemon, I made a new release of the ManageSieve service for Dovecot v1.1. This release includes two other small fixes as well. Changelog v0.10.5: - Fixed a segfault bug in the authentication time-out. Bug report and trace provided by Wolfgang Friebel. - Fixed maximum permissions for uploaded scripts; was 0777. This was shielded however by the default umask (not documented to be configurable), so the actual permissions would never have been 0777. - Fixed handling of ~/ in use of mail-data for script location The following files are released: ManageSieve package: http://www.rename-it.nl/dovecot/1.1/dovecot-1.1-managesieve-0.10.5.tar.gz http://www.rename-it.nl/dovecot/1.1/dovecot-1.1-managesieve-0.10.5.tar.gz.s… ManageSieve patch: http://www.rename-it.nl/dovecot/1.1/dovecot-1.1.9-managesieve-0.10.5.diff.gz http://www.rename-it.nl/dovecot/1.1/dovecot-1.1.9-managesieve-0.10.5.diff.g… Have fun testing the new releases and don't hesitate to notify me when there are problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl IRC: Freenode, #dovecot, S[r]us

[Dovecot] userdb didn't return a home directory with v1.1.7
by Ivars Strazdiņš 26 Jan '09

Hi all, I am running Dovecot v1.1.7 in a relatively quiet and calm environment. Suddenly overnight cron job has started throwing out errors like: /usr/sbin/dovecot --exec-mail ext /usr/lib/dovecot/expire-tool Error: userdb(user1(a)mail.example) didn't return a home directory Error: userdb(user2(a)mail.example) didn't return a home directory Indeed, running this command produces: ------------------------- $ sudo /usr/sbin/dovecot --exec-mail ext /usr/lib/dovecot/expire-tool --test Error: userdb(user1(a)mail.example) didn't return a home directory Info: User lookup failed: user1(a)mail.example Error: userdb(user2(a)mail.example) didn't return a home directory Info: User lookup failed: user2(a)mail.example ------------------------- Yet these mailboxes are valid, corresponding users can login, send and receive mail. Other mailboxes are OK, too. Where to to start looking? I found that similar error message with v1.1.6 is fixed in v1.1.7, but I am running v.1.1.7 already. Please see dovecot configuration below.

[Dovecot] Shared Mailboxes (symlink) and kmail: known issues?
by Wilhelm Meier 26 Jan '09

26 Jan '09

Hi, are there any known issues with symlinked-shared-mailboxes and kmail? I use virtual users (LDAP), so there are no unix-permissions related problems here: all mailboxes are owned by the local user vmail. Each user maildir has some symlinks to shared mailboxes. This works fine if I use squirrelmail as a MUA. kmail instead seems to have some problems: if I save a mail into the shared-folder, the other users are seeing this new mail almost immediately. But if I delete(!) a mail from the shared-folder, the list of the other kmails remains untouch. Refreshing does nothing. I have to close kmail and restart. Is this related to some sort of wrong config of the shared mailboxes or is this a (known) dovecot <-> kmail problem? -- Wilhelm

[Dovecot] Shared mailboxes support status
by Thomas Hummel 26 Jan '09

26 Jan '09

Hello Timo, I'm running dovecot-1.1.8 and I'm about to play with namespaces and shared mailboxes. I've read on the list that the Kolab people did contribute to that, and I read at http://dovecot.org/doc/NEWS-1.2 "+ Full support for shared mailboxes and IMAP ACL extension." I'd like to know the differences between shared mailboxes support between 1.1. and 1.2 branches and if it may be considered "safe" to use shared mailboxes on a production server running 1.1.8+ dovecot version (i.e. is it working and how, compared to the upcoming 1.2 release). I guess part of the answer is in the diffences between shared and public namespaces handling. Thanks -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] Postfix and Dovecot
by Leonardo Coelho 26 Jan '09

26 Jan '09

Hi Everybody, I'm mount two failover servers which use Postfix and Dovecot but the hostname of the machines r diferent: first node # uname -n # mail secound node #uname -n #mail2 So far so good, the real problem is that the e-mail file name on server is like this: 1232449377.P31789Q0M963611.mail2 and when I using the server called mail the file stay like this: 1232449377.P31789Q0M963611.mail I'm using drbd disk for the mailboxes and when I'm using the server called mail the files with mail2 on the end is not read for the dovecot when the user turn on the mail client but if I change the end from mail2 to mail that's ok the dovecot can read. How can I make dovecot read both files or any name on the end?

[Dovecot] Dovecot upgrade broke per-user Sieve scripts
by John Reese 25 Jan '09

25 Jan '09

Hi all, I'm migrating my private mail server from Dovecot 1.0.10 to Dovecot 1.1.4 (both the latest package in Ubuntu Hardy and Intrepid, resp.). I'm using Postfix with Postfixadmin virtual users , passing mail to Dspam, which in turn passes email to the Dovecot LDA. The relevant configuration section is attached below. When running on the old version of Dovecot, the LDA correctly executed either the user's personal sieverc script, or the global sieverc, as expected. However, after the upgrade to 1.1.4, Dovecot will not execute any per-user Sieve scripts, although the configuration and file permissions hasn't changed. I've added debug logging to Dovecot, and the relevant portions of the log file are also attached below. What am I missing here? Why can't cmusieve find the user's script?

[Dovecot] v1.1.9 released
by Timo Sirainen 23 Jan '09

23 Jan '09

http://dovecot.org/releases/1.1/dovecot-1.1.9.tar.gz http://dovecot.org/releases/1.1/dovecot-1.1.9.tar.gz.sig Lots of small dbox fixes, hopefully migrations from Maildir are now working correctly. I'm also planning on releasing v1.2.beta1 in a few days. + Sending SIGUSR2 to dovecot-auth now also logs statistics about cache inserts. This could help figuring out auth cache size. + deliver: Added rejection_subject setting, which is used for rejected mails. + pop3: Prevent clients from looping forever trying to fetch an expunged message. + If login process crashes, log the IP address that (maybe) caused it. + If core dump limit is 0, add "core dumps disabled" to startup log line. + Log better messages for "Permission denied" errors - mbox: Fixed assert-crash with pop3_lock_session=yes - dbox: Fixes to handling maildir-converted files. - Auth cache wasn't working correctly for all fields (e.g. allow_nets) with blocking passdbs (e.g. mysql). - pgsql: Handle reconnecting to server without failing auth lookups. - Berkeley DB memory/resource leak fixes. - maildir: Fixes to handling over 26 keywords.

[Dovecot] Sieve regex match problem
by Andy Howell 22 Jan '09

22 Jan '09

I'm trying to make a regex to match common mailing list addresses and file messages to corresponding folders. I'm using sieve-test to try and understand what is happening. The sieve script is: require [ "fileinto", "regex", "variables" ]; if header :regex ["Sender"] ["(.*>[ \\t]*,?[ \\t]*)?([^-@]*)-([^-@]*)(-bounces)?@antlr.org"] { fileinto "${0} :: 1:${1} 2:${2} 3:${3} 4:${4} 5:${5} 6:${6} 7:${7}"; } The email contains: Sender: antlr-interest-bounces(a)antlr.org I'm trying to form a folder from the first two parts of the sender. In the real script, that will do a "fileto antlr.interest;" Running sieve-test, I get: * store message in folder: antlr-interest-bounces(a)antlr.org :: 1: 2:antlr 3: 4:interest 5: 6:-bounces 7: I don't understand why parts 3 and 5 are empty. From the regex grouping, I expected Part 2 "antlr" Part 3 "interest" Part 4 "-bounces" The regex groups break done as: 1: (.*>[ \\t]*,?[ \\t]*)? - match leading name, comma or spaces 2: ([^-@]*) - match first part: 'antlr' in his case - - Hyphen between parts 3: ([^-@]*) - match second part: interest in this case 4: (-bounces)? - When cc'd, -bounces part isn't used The same regex tested with perl works as I expected. Without the first group of the regex '(.*>[ \\t]*,?[ \\t]*)?', it works correctly. That group isn't getting matched anyway, so it shouldn't matter. This is with 1.2alpha5. What am I missing? Thanks, Andy

[Dovecot] Migration question: .INBOX?
by Peter Lindgren 22 Jan '09

22 Jan '09

Hi, Not much left to fix in my migration script (moving between two dovecot servers). However, I discovered a mail folder .INBOX without cur, new and tmp subfolders, and the .imap.index files were rather old (feb 2006). Is this an old relic from early dovecot versions (I once ran 0.99 on this old server)? Or is it old client software? There are no data in it. TIA, Peter -- Peter Lindgren http://www.norrskenkonsult.com

[Dovecot] Intermittent "certificate cannot be verified" error
by Guy 22 Jan '09

22 Jan '09

Hi guys, Not sure where to start looking for this. I've got a few users getting intermittent "certificate cannot be verified" messages when connecting through SSL to Dovecot. Connections go through haproxy to Dovecot 1.1.8 on the back end servers. I've got verbose_ssl and auth_debug enabled. All I'm seeing on the logs for the time the users reported the error is this: Jan 21 23:30:51 mink dovecot: auth(default): new auth connection: pid=28811 Jan 21 23:30:51 mink dovecot: IMAP(user1(a)domain1.net): Disconnected in IDLE bytes=73/4235 Jan 21 23:24:23 mink dovecot: auth(default): new auth connection: pid=28811 Jan 21 23:24:23 mink dovecot: imap-login: Disconnected (no auth attempts): rip=x.x.x.x, lip=x.x.x.x Jan 21 23:24:23 mink dovecot: auth(default): new auth connection: pid=28811 Jan 21 23:24:24 mink dovecot: IMAP(user2(a)domain1.net): Disconnected in IDLE bytes=89/920 Since it's so intermittent I'm not sure where to start. Since there are no real errors in the Dovecot logs I'm suspecting that haproxy is perhaps not routing every packet correctly leading to Dovecot not getting all the data needed for the connection. Are there any other possibilities I've missed?

[Dovecot] Courier->dovecot migration script
by Warren Baker 22 Jan '09

22 Jan '09

HI All, We have the latest Dovecot 1.1.6 running and I need to migrate some POP3 users over from Courier to Dovecot and would need to convert the courierpop3dsizelist to maintain the UIDs. I just need to confirm that the script (http://www.dovecot.org/tools/courier-dovecot-migrate.pl) only works for Dovecot v1.0 and not for v1.1? As the dovecout-uidlist file that is created (by the script) is not in the same format as dovecot-uidlist file that is created by the 1.1.6 server. Thanks, Warren

Hello folks An Apple user here have troubles between Dovecot and its Apple mail client that presents ALL attachements inline inside emails instead of "Attachements" the problem occurs only when using IMAP , when using POP3 attachements appears as they are supposed to do. I would like to know if other Apple users in this list has experienced and solved that problem , the machine in running MacOS 10.5 Thanks a lot. -- Cordialement Frank Bonnet ESIEE Paris

[Dovecot] docecot managesieve global filter, service name
by Wolfgang.Friebel＠desy.de 21 Jan '09

21 Jan '09

I do have two questions related to the managesieve setup in dovecot 1) I did setup a global sieve filter, that is invoked if a user has no other sieve filter. If a user installs a sieve filter and activates it (PUTSCRIPT, SETACTIVE) then the sieve filter gets compiled (.sievec) and deliver does use it. If I want to deactivate the filter (SETACTIVE "") only the symlink (to the .sieve script) is removed, the .sievec file remains intact. On the other hand the dovecot documentation reads (http://wiki.dovecot.org/LDA/Sieve) To stop using sieve, both the .sieve source file and the compiled .sievec file must be deleted How can I let a user switch between the globally installed sieve filter and an own filter. Activation seems to be ok, but deactivation would not result in the switch back to the global filter if I believe the docs. 2) To use the SASL authentication with managesieve the name of the service has to be given. In the managesieve RFC http://tools.ietf.org/html/draft-ietf-sieve-managesieve-09 I can read (page13): The service name specified by this protocol's profile of SASL is "sieve". On the other hand I can find in managesieve-0.10.4 in client-authenticate.c #define MANAGESIEVE_SERVICE_NAME "managesieve" The name is important for the Kerberos5 auth I am doing, as I have to provide a service key for managesieve.hostname@REALM instead of sieve.hostname@REALM. Currently I have adapted my auth to the "managesieve" service name but maybe that should be changed. My Installation: dovecot 1.1.8 patched for dovecot-1.1-managesieve-0.10.4 Authentication using SASL (GSSAPI), contained in the perl Module Net::ManageSieve on CPAN. -- Wolfgang Friebel Deutsches Elektronen-Synchrotron DESY Phone/Fax: +49 33762 77372/216 Platanenallee 6 Mail: Wolfgang.Friebel AT desy.de D-15738 Zeuthen Germany

[Dovecot] Questions regarding Dovecot's POP3 implementation
by Dale Gallagher 21 Jan '09

21 Jan '09

Hi all I'm considering moving over my POP3 service from qmail-pop3d to Dovecot for the following reasons: - Support for Maildir++ which I have yet to implement - Already using Dovecot for IMAP, so makes sense i.t.o Maildir++ - Support for SQL based user authentication My primary concerns are performance and security. Before I go down that route of migrating away from qmail-pop3d, I'd appreciate some answers and feedback on the following. There is mention of the Maildir filename extension W= for virtual file size here: http://wiki.dovecot.org/POP3Server However, I can't find any MDAs which support writing the filename in this format. Maildrop seems to support S= only? If Dovecot is only able to read W= in the filename, I would imagine that it might make sense to have an MDA like Maildrop write the message to disk, replacing all LF with CR+LF and finally write the filename with identical S= and W= filename extensions included? Example: Maildrop replaces all LFs with CR+LF in incoming message. Maildrop writes message as: 1035478339.27041_118.foo.org,S=1000,W=1000 (where 1000 is the file's RFC822.SIZE) Then Dovecot doesn't have to calculate virtual message sizes. I've also found this thread: http://markmail.org/message/oznf2f7m7hvsxqn6 ... which suggests changing mail_get_virtual_size to mail_get_physical_size in src/pop3/client.c Would this read the size from S=, or do a stat()? 5. Does anyone use Dovecot pop3 service on thousands of mailboxes and if so, what specific tweaks / setup do you use? Thanks Dale

[Dovecot] deliver rejection bounces

Is there any reason not to make (for v1.2) 1) deliver -e behavior the defaut? 2) not even provide the option for the current default (have deliver send bounces itself)? The only reason it even works like it does currently is because I just mostly copied what Cyrus did.

[Dovecot] Active Directory authentication

Hello all I would like to ask if there is adequate mechanism to authenticate users through POP3 against Active Directory by Outlook Express so that users will authenticate seamlessly using logon credentials. I have implemented LDAP authentication but users must supply their credentials to Outlook Express although they have logged on to Windows (AD). the ntlm auth in Dovecot 1.1 (windind) satisies this requirement (no credentials in Outlook)? thanks Dimitrios

[Dovecot] Move from 1.0.rc29 to 1.1.7?
by Peter Lindgren 21 Jan '09

21 Jan '09

Hello! I am moving my mail from the old server with 1.0.rc29 to a brand new server with 1.1.7. I use Maildir in both servers. A few questions: 1) The new server has another name, can I just copy the mail files as-is, will the server name in the file names matter? 2) The new server has a different architecture and different endian, so I plan not to copy the index and cache files; they seem to have become broken from time to time in the old server anyway. Dovecot will also re-create them when needed. Ok? 3) 1.0.rc29 did not store the message size in the file name as later versions. When will Dovecot do the check and rename the files to include the message size? There are some folders with quite large number of messages, the largest is some 45,000 messages. TIA, /Peter -- Peter Lindgren http://www.norrskenkonsult.com

[Dovecot] Dovecot optimisation
by Proskurin Kirill 20 Jan '09

20 Jan '09

Hello all. We start to use Dovecot at our email production but it runs not such fast as we expect. We use Dell 2950 with 4GbRAM at FreeBSD-7.0-p9 - load avarage never upper a 0.5 We have about 500 clients most of it use Outlook 2007 via IMAP. We run in this problems: 1) Sync of imap folder is really slow(I think it is Outlook problem) 2) Time after time we got Sync error from outlook 3) Time after time our monitoring system says what IMAP port not answer in 10 sec. In real life it start to answer in 15-20 sec what is not really good - client thinks what server don`t work. If I restart dovecot - it start to answer in 1-3 sec. I think problem in my conf, may be I need tune it? *dovecot -n don`t give full conf so i use this:* mail# grep -v '#' /usr/local/etc/dovecot.conf | egrep -v '^$' base_dir = /var/run/dovecot/ protocols = imap imaps pop3 pop3s managesieve listen = * disable_plaintext_auth = yes shutdown_clients = yes log_path = /var/log/dovecot/dovecot.log info_log_path = /var/log/dovecot/dovecot.log log_timestamp = "%b %d %H:%M:%S " syslog_facility = mail ssl_disable = no ssl_cert_file = /usr/local/etc/certs/fxclub_org.crt ssl_key_file = /usr/local/etc/certs/fxclub_org.key ssl_ca_file = /usr/local/etc/certs/GlobalSignCA.crt ssl_verify_client_cert = no ssl_parameters_regenerate = 168 ssl_cipher_list = ALL:!LOW:!SSLv2 verbose_ssl = no login_dir = /var/run/dovecot/login login_user = dovecot login_process_size = 64 login_process_per_connection = yes login_processes_count = 10 login_max_processes_count = 128 login_greeting = Dovecot ready. login_log_format_elements = user=<%u> method=%m rip=%r lip=%l %c login_log_format = %$: %s mail_location = maildir:/var/spool/dovecot/domains/%d/%n/ mail_uid = dmail mail_gid = dmail mail_privileged_group = mail mail_full_filesystem_access = no mail_debug = no mail_log_prefix = "%Us(%u): " mail_log_max_lines_per_sec = 10 mmap_disable = no dotlock_use_excl = yes fsync_disable = no mail_nfs_storage = no mail_nfs_index = no lock_method = fcntl mail_drop_priv_before_exec = no verbose_proctitle = yes first_valid_uid = 500 first_valid_gid = 0 max_mail_processes = 512 mail_process_size = 256 mail_max_keyword_length = 50 mail_cache_min_mail_count = 0 mailbox_idle_check_interval = 30 mail_save_crlf = no maildir_stat_dirs = no maildir_copy_with_hardlinks = yes maildir_copy_preserve_filename = no mbox_read_locks = fcntl mbox_write_locks = dotlock fcntl mbox_lock_timeout = 300 mbox_dotlock_change_timeout = 120 mbox_min_index_size = 0 protocol imap { login_executable = /usr/local/libexec/dovecot/imap-login mail_executable = /usr/local/libexec/dovecot/imap imap_max_line_length = 65536 mail_max_userip_connections = 10 mail_plugins = quota imap_quota autocreate mail_plugin_dir = /usr/local/lib/dovecot/imap login_greeting_capability = yes imap_logout_format = bytes=%i/%o imap_client_workarounds = delay-newmail tb-extra-mailbox-sep } protocol pop3 { login_executable = /usr/local/libexec/dovecot/pop3-login mail_executable = /usr/local/libexec/dovecot/pop3 pop3_enable_last = no pop3_lock_session = no pop3_uidl_format = %08Xu%08Xv pop3_logout_format = top=%t/%p, retr=%r/%b, del=%d/%m, size=%s mail_max_userip_connections = 3 mail_plugins = quota mail_plugin_dir = /usr/local/lib/dovecot/pop3 pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } protocol lda { postmaster_address = postmaster(a)fxclub.org hostname = mail.fxclub.org mail_plugins = cmusieve quota mail_plugin_dir = /usr/local/lib/dovecot/lda quota_full_tempfail = yes deliver_log_format = msgid=%m: %$ log_path = /var/log/dovecot/deliver.log info_log_path = /var/log/dovecot/deliver.log sendmail_path = /usr/sbin/sendmail rejection_reason = Your message to <%t> was automatically rejected:%n%r auth_socket_path = /var/run/dovecot/auth-master sieve_global_path = /var/spool/dovecot/global.sieve } protocol managesieve { listen = *:2000 login_executable = /usr/local/libexec/dovecot/managesieve-login mail_executable = /usr/local/libexec/dovecot/managesieve managesieve_max_line_length = 65536 sieve_storage = % sieve = ~/.dovecot.sieve mail_location = managesieve_implementation_string = dovecot } auth_executable = /usr/local/libexec/dovecot/dovecot-auth auth_process_size = 256 auth_cache_size = 0 auth_cache_ttl = 3600 auth_cache_negative_ttl = 3600 auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@ auth_username_format = %Lu auth_verbose = yes auth_debug = no auth_debug_passwords = no auth_worker_max_count = 100 auth_failure_delay = 2 auth default { mechanisms = plain login passdb ldap { args = /usr/local/etc/dovecot-ldap.conf } userdb ldap { args = /usr/local/etc/dovecot-ldap.conf } user = dovecot-auth count = 1 ssl_require_client_cert = no socket listen { master { path = /var/run/dovecot/auth-master mode = 0600 user = dmail } client { path = /var/run/dovecot/auth-client mode = 0660 user = exim } } } dict { } plugin { quota = maildir quota_rule = *:storage=1024M quota_rule2 = Trash:storage=1256M quota_rule3 = SPAM:ignore quota_warning = storage=95%% /usr/local/bin/quota-warning.sh 95 quota_warning2 = storage=80%% /usr/local/bin/quota-warning.sh 80 autocreate = Trash autocreate2 = Sent autocreate3 = Spam autosubscribe = Trash autosubscribe2 = Sent autosubscribe3 = Spam } -- Best regards, Proskurin Kirill

[Dovecot] redirecting temp email files to another directory
by JANE CUA 20 Jan '09

20 Jan '09

Hi, Is is possible to redirect temp email files to another folder like /tmp or somewhere else, instead of having it in the same /var/spool where the mbox is?

[Dovecot] Errmsgs b4 and after migration DC V1.0.15 to V1.1.8
by Stewart Dean 20 Jan '09

20 Jan '09

Last Wednesday at 12:21 I made this switch, which seemed to be uneventful. In any case, no user has reported problems since the migration. Not content to leave well enough alone, this morning I scanned the syslog and maillog for dovecot related errors. What I found was that: Before the Migration=========================== I saw a lot of SSL errors that look like this: > Jan 14 11:49:23 mercury mail:warn|warning dovecot: imap-login: SSL_read() syscall failed: Connection reset by peer [69.180.200.184] > Jan 14 11:52:28 mercury mail:warn|warning dovecot: imap-login: SSL_read() syscall failed: Connection reset by peer [68.6.82.45] Which l took to be breakin attempts of some sort, except that I haven't seen any since the migration! After the migration==================================== I see errors like this: > Jan 14 12:21:45 mercury mail:err|error dovecot: IMAP(eg115): Corrupted index cache file /var/dcindx/eg115/.imap/INBOX/dovecot.index.cache: Broken MIME parts for mail UID 1934 > Jan 14 12:21:46 mercury mail:err|error dovecot: IMAP(alexande): Corrupted index cache file /var/dcindx/alexande/.imap/INBOX/dovecot.index.cache: Broken MIME parts for mail UID 132641 > Jan 14 12:21:46 mercury mail:err|error dovecot: IMAP(ls454): Corrupted index cache file /var/dcindx/ls454/.imap/INBOX/dovecot.index.cache: Broken MIME parts for mail UID 47 > Jan 14 12:21:46 mercury mail:err|error dovecot: IMAP(tr489): Corrupted index cache file /var/dcindx/tr489/.imap/INBOX/dovecot.index.cache: Broken MIME parts for mail UID 1 > Jan 14 12:21:54 mercury mail:err|error dovecot: IMAP(bh265): Corrupted index cache file /var/dcindx/bh265/.imap/INBOX/dovecot.index.cache: Broken MIME parts for mail UID 2 > Jan 14 12:22:01 mercury mail:err|error dovecot: IMAP(crouch): Corrupted index cache file /var/dcindx/crouch/.imap/INBOX/dovecot.index.cache: Broken MIME parts for mail UID 4863 > It appears that this error appears the first time a folder is referenced, then not again (I think but am not absolutely positive). Did the indexing method/format change in some way that would cause this (and Dovecot heals itself!) ? Is there any continuing problem inherent in this that needs to be dealt with?

[Dovecot] Coding question again...
by Stefan Jurisch 20 Jan '09

20 Jan '09

Hello again, I have a coding question again: I can obtain the path of the current user's mailbox with the function mail_storage_get_mailbox_path(...) - so far so good. But is it possible to get this mailbox path for another user than the logged in one? Thanks in advance. Best regards.

Hi i want to migrate from dbmail to dovecot, the main problem is passwords. dbmail uses "md5-hash" wich crypt "111" to "$1$tZNR7pR4$jMuuKWm7ljRyL8iEMfjep.". Tried all dovecot pass schemes thru `dovecotpw` and no one matches. The main question is how to migrate dbmail -> dovecot.
