[Dovecot] Dovecot newbie (migrating from qmail)
by Ajai Khattri 13 Nov '12

13 Nov '12

Ive been using qmail+vpopmail+courier-imap for many years but its time to retire that server so I thought this might be an opportunity to see how I could use Postfix and Dovecot to provide the same services. Im running Dovecot 2.1.9 and Postfix 2.9.4. I have spent a few days reading through some of the docs on the wiki (there's doesn't seem to be any large overview of Dovecot concepts or books so bear with me). Im thinking something simple like passwd-file setup would suffice for me. I want to use completely virtual users. Id like to store mail under /home/vmail/$domain/$user. I think Ive figured out how to do that. But how do I create the maildir? I understand the need to have a mail directory but also a directory for things like sieve - how to specify that? Im thinking the structure would be something like: /home/vmail/$domain/$user/mail <-- mail stored here /home/vmail/$domain/$user/ <-- sieve and other sundry store here Or should the sieve stuff also be under its own folder alongside the maildir? Is it possible to have a separate passwd file per domain? It is possible to combine password and userdb files into one per domain? (I prefer to keep all files related to each domain in its own folder). Also would like to configure Postfix to use dovecot-sasl and I want to use dovecot-lmtp for deliveries. Any good docs / example on those? Later on, I think I want to integrate some kind of virus and spam filtering (amavisd and maybe dspam - anybody used those? would I configure Postfix to handle that or dovecot-lmtp?) Im sure Ill have more questions as I get more complicated but baby steps for now. -- Aj.

[Dovecot] Problem importing messages with lazy_expunged configured

Hello, I have a problem importing messages since I have configured lazy_expunge. My lazy_expunge configuration (that is correctly working when a message is expunged) is: plugin { lazy_expunge = BORRADOS. } namespace { hidden = yes list = no location = maildir:~/Maildir/expunged prefix = BORRADOS. separator = . } but when I try to import messages I get: amateo_adm@myotis31:~$ sudo doveadm -vD import -u angel.luis maildir:/tmp/angel.luis '' mailbox INBOX doveadm(root): Debug: Loading modules from directory: /usr/lib/dovecot/modules doveadm(root): Debug: Module loaded: /usr/lib/dovecot/modules/lib02_lazy_expunge_plugin.so doveadm(root): Debug: Module loaded: /usr/lib/dovecot/modules/lib10_quota_plugin.so doveadm(root): Debug: Module loaded: /usr/lib/dovecot/modules/lib20_zlib_plugin.so doveadm(root): Debug: Loading modules from directory: /usr/lib/dovecot/modules/doveadm doveadm(root): Debug: Skipping module doveadm_acl_plugin, because dlopen() failed: /usr/lib/dovecot/modules/doveadm/lib10_doveadm_acl_plugin.so: undefined symbol: acl_user_module (this is usually intentional, so just ignore this message) doveadm(root): Debug: Skipping module doveadm_expire_plugin, because dlopen() failed: /usr/lib/dovecot/modules/doveadm/lib10_doveadm_expire_plugin.so: undefined symbol: expire_set_deinit (this is usually intentional, so just ignore this message) doveadm(root): Debug: Module loaded: /usr/lib/dovecot/modules/doveadm/lib10_doveadm_quota_plugin.so doveadm(root): Debug: Module loaded: /usr/lib/dovecot/modules/doveadm/lib10_doveadm_zlib_plugin.so doveadm(root): Debug: Skipping module doveadm_fts_plugin, because dlopen() failed: /usr/lib/dovecot/modules/doveadm/lib20_doveadm_fts_plugin.so: undefined symbol: fts_backend_rescan (this is usually intentional, so just ignore this message) doveadm(root): Debug: Effective uid=0, gid=0, home=/home/amateo_adm doveadm(root): Debug: Quota root: name=User quota backend=dict args=:file:/home/amateo_adm/Maildir/dovecot.quota doveadm(root): Debug: Quota rule: root=User quota mailbox=* bytes=10737418240 messages=0 doveadm(root): Debug: Quota rule: root=User quota mailbox=Trash bytes=+1073741824 messages=0 doveadm(root): Debug: dict quota: user=doveadm, uri=file:/home/amateo_adm/Maildir/dovecot.quota, noenforcing=0 doveadm(root): Debug: maildir++: root=/tmp/angel.luis, index=, control=, inbox=/tmp/angel.luis, alt= doveadm(root): Fatal: lazy_expunge: Unknown namespace: 'BORRADOS.' in /tmp/<user> I don't have any "expunged" folder, it is just a maildir.

[Dovecot] Commercial features in Dovecot future: Object storage, archive
by Timo Sirainen 13 Nov '12

13 Nov '12

Hi all, Dovecot Oy’s web pages at www.dovecot.fi have been updated. The products page lists two features that will be available for commercial licensing, extending the functionality of the basic open-source version of Dovecot. * Storing emails to (high-latency) object storage, initially supporting Amazon S3, Caringo CAStor and Scality. * Email archive storage. See http://www.dovecot.fi/products/index.html for details. I’ve been developing Dovecot for over 10 years now. For a long time it was my primary motivation in life to create the best IMAP server available :) I think I've pretty much accomplished that by now. The future is looking very bright for Dovecot: we will continue the open source development stronger than ever, but in addition, for the long term it needs some additional licensed components that bring the money to cover the cost for future Dovecot development and to be able to build up the support in a professional way. These new features will be added as plugins on top of Dovecot to extend the functionality. Note that I’m not just randomly choosing which features will be open and which will be licensed. Only some specific features will be licensed where my company is going to make money with partnerships and in other measurable ways.

[Dovecot] mbox vs. maildir storage block waste
by Christoph Anton Mitterer 13 Nov '12

13 Nov '12

Hi. I recently mentioned in several posts, that I'd tended to use mbox rather than maildir, because you don't loose so much space (due to always allocating full blocks per maildir file and thus per mail). I made some tests of my archive, which consists of some 3,4 million mails at a total of 42GB). Most of these mails are probably normal sized, but there are also some with bigger attachments. For those who are interested here are the results: I used a 53687091200 B image file (via loop device) and tested ext4 only. btrfs is IMHO not yet ready, I have had often issues with XFS (corruptions), reiser4 is more or less dead and reiser3 is said to have issues (see e.g. its wikipedia article, even though it has that mode for small files which would fit nicely). As you see the number of mails increased a bit, cause I tested over several days... but this is only a very small increase so it shouldn't change the numbers a lot. 1) Original mbox archives (right now in Evolution) mbox exact space: 38122676224 (does not include meta-data) mbox guess space: 44625670144 (includes Evolution meta-data which is several GBs) mbox num mails: 3412999 (occurances of From_ lines) In the following: - image file, 1B-blocks, Used_begin, Used_end, Available_begin, Available_end result out of df -B 1 - mdir exact used space is the sum of du -B 1 for each regular file (i.e. each mdir file) - mdir guess used space du -B 1 on the root dir of the filesystem - mdir num mails: find . type -f | wc -l on the root dir of the filesystem 2) EXT4 with 4096 blocks: image file: 53687091200 1B-blocks: 52844687360 Used_begin: 188555264 Used_end: 45198778368 Available_begin: 49971777536 Available_end: 2444972032 mdir exact used space: 44810866688 mdir guess used space: 45010243584 mdir num mails: 3423296 delta: 6.688190464 G delta / mail: 1953 B 3) EXT4 with 2048 blocks: image file: 53687091200 1B-blocks: 50324295680 Used_begin: 82857984 Used_end: 41598846976 Available_begin: 47557083136 Available_end: 6041094144 mdir exact used space: 41323991040 mdir guess used space: 41516007424 mdir num mails: 3425033 delta: 3.201314816 G delta / mail: 934 B 4) EXT4 with 1024 blocks: image file: 53687091200 1B-blocks: 50314834944 Used_begin: 38287360 Used_end: 39909360640 Available_begin: 47592193024 Available_end: 7721119744 mdir exact used space: 39683908608 mdir guess used space: 39871086592 mdir num mails: 3425033 delta: 1.561232384 G delta / mail: 455 B As you can see, the delta per mail is rather close to the statistically expected values of 2048B, 1024B and 512B. In the end I probably changed my opinion. ~7GB of wasted block space for all my mails is actually quite a lot, but in days of cheap disk space it's acceptable. And with mbox one has IMHO the major disadvantage that mailservers (including dovecot) store some meta-data _in_ it (i.e. in the mails themselves) , which I don't like a lot. I still think about reports that mbox is much faster with full text search (which sounds reasonable)... but therefore one needs probably and database backend anyway. HTH, Chris.

[Dovecot] Invalid Managesieve commands are counted twice
by Christoph Bußenius 12 Nov '12

12 Nov '12

Hi, the Managesieve server closes the connection if it receives an unknown command before authentication: "IMPLEMENTATION" "Dovecot Pigeonhole" "SIEVE" "fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave" "NOTIFY" "mailto" "SASL" "PLAIN" "STARTTLS" "VERSION" "1.0" OK "Dovecot ready." --> BOGUS NO "Error in MANAGESIEVE command received by server." NO "Error in MANAGESIEVE command received by server." BYE "Too many invalid MANAGESIEVE commands." Connection closed by foreign host. Note that only one bogus command has been sent by the client, however the server sends two identical error messages. This seems to be a bug in Pigeonhole 0.3.3. In version 0.2.6, the connection was kept open after the error message. This is actually important to us because we use the "sieveshell" utility which is shipped with the Python "managesieve" package. The managesieve.py module always sends a BOGUS command after the TLS handshake. According to its comments, this is done to work around problems with other server implementations: # Some servers send capabilities after TLS handshake, some # do not. We send a bogus command, and expect a NO. If you # get something else instead, read the extra NO to clear # the buffer. typ, data = self._command('BOGUS') (The full source is at http://pydoc.net/managesieve/0.4.2/managesieve) As a result, sieveshell cannot be used with TLS and a current Dovecot/Pigeonhole server.

[Dovecot] Sieve users script problem.

[Dovecot] Solr 4.0 - lucene - FTS
by Charles Marcus 12 Nov '12

12 Nov '12

Hi Timo, As one who is interested in implementing FTS sometime in the future, I'm curious about what is in store as far as improvements go... Specifically, any plans for implementing immediate/automatic index updates at delivery time? The lack of automatically updated indexes is one downside for its implementation... Also, does the release of Solr 4.0 mean anything for the lucene library used by dovecot? http://www.marketwatch.com/story/lucidworks-congratulates-apache-foundation… Thanks, -- Best regards, Charles

[Dovecot] Sieve puts incoming message into inbox on any problem with submission_host
by Christian Rohmann 12 Nov '12

12 Nov '12

Hello dovecot-users, I have a question/suggestion regarding the submission_host feature of the lda (either via dovecot-lda binary or lmtp) in combination with sieve. When trying to deliver message to a mailbox and this message has a sieve redirect action applied to it, dovecot is using the configured smtp server to forward the message just fine. Unfortunately, if the server configured for submission is unavailable, returns an error or cannot be found via DNS, sieve will simply put the message into the inbox and be done with it: --- dovecot.log --- dovecot: lda(user1): Error: lmtp client: DNS lookup of idonotexist.example.com failed: Name or service not known dovecot: lda(user1): Error: sieve: msgid=unspecified: failed to redirect message to <user2> (refer to server log for more information) dovecot: lda(user1): sieve: msgid=unspecified: stored mail into mailbox 'INBOX' dovecot: lda(user1): Error: sieve: execution of script /mailboxes/user1/.dovecot.sieve failed, but implicit keep was successful (user logfile /mailboxes/user1/.dovecot.sieve.log may reveal additional details) --- /dovecot.log --- The same applies to vacation messages being sent out. Especially with an (unconditional) redirect action, users don't expect to find messages in their inbox. Also problems with the submission_host could very much be temporary and a little delay in delivering a message is better then putting it somewhere the user doesn't expect a message to be. Is there any way to change the behavior of dovecot or the sieve plugin to tempfail in case a message cannot be sent out? I know that with multiple sieve actions it gets more complicated as there could be corner cases were the first message can be sent via the submission server and another message produced by the same sieve script cannot. I'd love sieve to behave like this: a) if submission host is unreachable (hostname wrong, timeout, ...) -> tempfail b) if submission host returns 4xx error -> tempfail c) if submission host returns 5xx error -> fail(-save) and just drop the message into inbox or even have an option to reject the message completely in this case. In case of a tempfail response, the mta simply queues the message and tries again later. In case of a permanent fail the mta will create a bounce message to in form the sender. Regards and have a great weekend, Christian

[Dovecot] quota recalc does not work
by Adrian Stoica 09 Nov '12

09 Nov '12

Hi I upgraded dovecot from 2.0 to 2.1 , and now i face the quota recalc problem. All settings are keep in mysql Before , after a change in mailbox.quota field, i run doveadm quota recalc and all was ok , but now that command doesn't do anything. After i change a quota for a user , i have to restart dovecot to get the new quota , or do a "doveadm reload" instead of recalc.

[Dovecot] Mails don't get deleted after POP3
by cullinan＠rocketmail.com 09 Nov '12

09 Nov '12

Hi, there! Well, I am new to dovecot, so please be patient with me: I have a virtual server and want to setup simple mail delivery. postfix, saslauthd and dovecot basically work fine. The only open issue is, that (I guess) dovecot doesn't remove the mail when it's retrieved via pop3 from the server. It keeps sending me the same emails again and again. (The mail client (Thunderbird) is configured to remove the messages from the server - it was working already.) I guess that dovecot cannot write to some files / has problems with write permissions. But it doesn't tell me anything... Can you tell me, what configuration might be wrong or how can I enable more debugging to see what dovecot is doing after the mails got sent out via pop3? Here is the configuration: # dovecot -n # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.38-8-server x86_64 Ubuntu 11.04 log_timestamp: %Y-%m-%d %H:%M:%S protocols: pop3 pop3s login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/pop3-login mail_privileged_group: mail mbox_write_locks: fcntl dotlock mail_executable: /usr/lib/dovecot/pop3 mail_plugin_dir: /usr/lib/dovecot/modules/pop3 auth default: passdb: driver: pam userdb: driver: passwd -----8<----- # dovecot -a # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.38-8-server x86_64 Ubuntu 11.04 base_dir: /var/run/dovecot log_path: info_log_path: log_timestamp: %Y-%m-%d %H:%M:%S syslog_facility: mail protocols: pop3 pop3s listen: * ssl_listen: ssl: yes ssl_ca_file: ssl_cert_file: /etc/ssl/certs/dovecot.pem ssl_key_file: /etc/ssl/private/dovecot.pem ssl_key_password: ssl_parameters_regenerate: 168 ssl_cipher_list: ssl_cert_username_field: commonName ssl_verify_client_cert: no disable_plaintext_auth: yes verbose_ssl: no shutdown_clients: yes nfs_check: yes version_ignore: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/pop3-login login_user: dovecot login_greeting: Dovecot ready. login_log_format_elements: user=<%u> method=%m rip=%r lip=%l %c login_log_format: %$: %s login_process_per_connection: yes login_chroot: yes login_trusted_networks: login_process_size: 64 login_processes_count: 3 login_max_processes_count: 128 login_max_connections: 256 valid_chroot_dirs: mail_chroot: max_mail_processes: 512 mail_max_userip_connections: 10 verbose_proctitle: no first_valid_uid: 500 last_valid_uid: 0 first_valid_gid: 1 last_valid_gid: 0 mail_access_groups: mail_privileged_group: mail mail_uid: mail_gid: mail_location: mail_cache_fields: mail_never_cache_fields: imap.envelope mail_cache_min_mail_count: 0 mailbox_idle_check_interval: 30 mail_debug: no mail_full_filesystem_access: no mail_max_keyword_length: 50 mail_save_crlf: no mmap_disable: no dotlock_use_excl: yes fsync_disable: no mail_nfs_storage: no mail_nfs_index: no mailbox_list_index_disable: yes lock_method: fcntl maildir_stat_dirs: no maildir_copy_with_hardlinks: yes maildir_copy_preserve_filename: no maildir_very_dirty_syncs: no mbox_read_locks: fcntl mbox_write_locks: fcntl dotlock mbox_lock_timeout: 300 mbox_dotlock_change_timeout: 120 mbox_min_index_size: 0 mbox_dirty_syncs: yes mbox_very_dirty_syncs: no mbox_lazy_writes: yes dbox_rotate_size: 2048 dbox_rotate_min_size: 16 dbox_rotate_days: 1 mail_drop_priv_before_exec: no mail_executable: /usr/lib/dovecot/pop3 mail_process_size: 256 mail_plugins: mail_plugin_dir: /usr/lib/dovecot/modules/pop3 mail_log_prefix: %Us(%u): mail_log_max_lines_per_sec: 10 imap_max_line_length: 65536 imap_capability: imap_client_workarounds: imap_logout_format: bytes=%i/%o imap_id_send: imap_id_log: imap_idle_notify_interval: 120 pop3_no_flag_updates: no pop3_enable_last: no pop3_reuse_xuidl: no pop3_save_uidl: no pop3_lock_session: no pop3_uidl_format: %08Xu%08Xv pop3_client_workarounds: pop3_logout_format: top=%t/%p, retr=%r/%b, del=%d/%m, size=%s dict_db_config: dict_process_count: 1 managesieve_max_line_length: 65536 managesieve_logout_format: bytes=%i/%o managesieve_implementation_string: dovecot auth default: mechanisms: plain realms: default_realm: cache_size: 0 cache_ttl: 3600 cache_negative_ttl: 3600 executable: /usr/lib/dovecot/dovecot-auth user: root chroot: username_chars: abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@ username_translation: username_format: master_user_separator: anonymous_username: anonymous krb5_keytab: gssapi_hostname: winbind_helper_path: /usr/bin/ntlm_auth failure_delay: 2 verbose: no debug: no debug_passwords: no ssl_require_client_cert: no ssl_username_from_cert: no use_winbind: no count: 1 worker_max_count: 30 process_size: 256 passdb: driver: pam args: deny: no pass: no master: no userdb: driver: passwd args: -----8<----- Please let me know if you need more.

[Dovecot] Dovecot ok for port 110, but not for SSL (beginner asking)
by ycc_Swe 09 Nov '12

Hello, I just installed Dovecot. It works for plaintext autorization, port 110. It has connected with Telnet, Thunderbird and an on-line pop3 client. Telnet: +OK Dovecot ready. user nnnnn -ERR Unknown command. user nnnnn +OK pass xxxxxxxxxx +OK Logged in. stat +OK 1 1553 retr 1 +OK 1553 octets Return-path: <sssssss(a)hotmail.com> Envelope-to: nnnnnn(a)mydomain.com Delivery-date: Tue, 06 Nov 2012 12:02:28 +0100 Received: from bay0-xcvxcv-xvxcv.bay333.hotmail.com ([123.123.123.123]) by deb7.pc with esmtp (Exim 4.80) But when I try ssl (port 995) with an on-line pop3 client, it will not work: /var/log/mail.log Nov 7 02:46:55 deb7 dovecot: pop3-login: Disconnected (no auth attempts in 0 secs): user=<>, rip=12.12.12.7, lip=123.123.123.123, TLS: Disconnected, session=<Iza75N3NlABBNykH> Nov 7 02:46:56 deb7 dovecot: pop3-login: Disconnected (no auth attempts in 1 secs): user=<>, rip=12.12.12.7, lip=123.123.123.123, TLS: Disconnected, session=<nWTF5N3NlQBBNykH> root@deb7:~# doveconf -n # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-3-686-pae i686 disable_plaintext_auth = no mail_gid = mail mail_location = mbox:~/mail:INBOX=/var/mail/%u namespace inbox { inbox = yes location = prefix = } passdb { args = username_format=%u /etc/dovecot/users driver = passwd-file } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = " imap pop3" ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = username_format=%u /etc/dovecot/users driver = passwd-file } I know very little about mail and ssl.

The following two files contain ssl keys: ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem I have tried changing the ssl parameter ("yes", "required") in 10-ssl.conf but with no change except that port 110 login becomes disabled. As you can see I am a beginner with Dovecot, I hope it is still OK to ask on this mailing list.

The current stable release is RHEL 6.3, released in June 2012. What is the valid reason preventing you from upgrading to the 6.x distribution? The packages in general in 6.x are 5 years newer than 5.x. And given the fact that RHEL runs miles behind the bleeding edge, you're way behind the curve even with a recent RHEL distribution. You can probably find a much newer version of Dovecot in an RPM somewhere, and Postfix for that matter. But it would be better for you if you simply upgraded to RHEL 6.3. -- Stan

[Dovecot] pop3 exim4 dovecot
by Patrick Shirkey 08 Nov '12

08 Nov '12

Hi, I have an exim4 and dovecot system. The system has multiple accounts. Exim4 is receiving emails in the /var/mail/user files and dovecot is configured to use /home/user/mail (mbox) folder. I have one account that dovecot is not processing replies/bounces/etc... The data is being written in the /var/mail/user file by exim4 but as far as dovecot is aware there is nothing in the pop3 inbox. Can anyone suggest how I can enable dovecot to know that the data is in the /var/mail/user file and deliver it to the pop3 inbox for this account? -- Patrick Shirkey Boost Hardware Ltd

[Dovecot] v2.2.alpha1 released
by Timo Sirainen 08 Nov '12

08 Nov '12

http://dovecot.org/releases/2.2/alpha/dovecot-2.2.alpha1.tar.gz http://dovecot.org/releases/2.2/alpha/dovecot-2.2.alpha1.tar.gz.sig I wanted to start stabilizing v2.2 release some months ago already, but I somehow got stuck adding more and more features. Now it looks like all of the necessary API changes are done, so everything I'm planning on near future can still be added to v2.2 without major changes. The redesigned dsync hasn't had much testing yet, so avoid running it with important mails. Would be nice if people started testing and reporting any bugs. I was going to create some kind of a test suite for testing all the possible syncing combinations and also doing some random stress testing, but I haven't had time for that yet. The new dsync supports doing very fast syncs by saving the resulting state and giving it as command line parameter to the next sync. So for example doveadm sync -s "" > new-state saves the state and doveadm sync -s `cat new-state` continues from the saved state. The replicator code doesn't yet support this. * When creating home directories, the permissions are copied from the parent directory if it has setgid-bit set. For full details, see http://wiki2.dovecot.org/SharedMailboxes/Permissions * "doveadm auth" command was renamed to "doveadm auth test" * IMAP: ID command now advertises server name as Dovecot by default. It was already trivial to guess this from command replies. + Implemented IMAP MOVE and BINARY extensions + Implemented IMAP CATENATE, URLAUTH and URLAUTH=BINARY extensions (by Stephan Bosch). + Implemented IMAP NOTIFY extension. Requires mailbox_list_index=yes to be enabled. + Redesigned and rewritten dsync. The new design makes the syncing faster, more reliable and more featureful. The new dsync protocol isn't backwards compatible with old dsync versions (but is designed to be forwards compatible with future versions). + All mailbox formats now support per-user message flags for shared mailboxes by using a private index. It can be enabled by adding :INDEXPVT=<path> to mail location. This should be used instead of :INDEX also for Maildir/mbox to improve performance. + Improved mailbox list indexes. They should be usable now, although still disabled by default. + Added LAYOUT=index. The mailbox directories are created using their GUIDs in the filesystem, while the actual GUID <-> name mapping exists only in the index. + LMTP proxy: Implemented XCLIENT extension for passing remote IP address through proxy.

Re: [Dovecot] Android ICS stock client and IMAP Capability issue.
by Massimiliano Cianelli 08 Nov '12

08 Nov '12

Hi, Yes w/o prefix work as expected, try to add a prefix like courier does (eg. Inbox.) It will not work as expected. Due I'm upgrading an old installed server, I've to keep everything as much transparent I can... it includes IMAP folder and subscription. Looking at that I've encountered that issue, and analyzed for fix it (thank you open source), not everyone will want to use/use k9.. but you can be 100% sure the stock client is there. Due that Google act like BlackBerry, Microsoft,etc.. (hovewer they will not fix it soon, or really respect the rfc), it's much simple add Namespace on prelogin banner then wait or have to tell someone to install another client for that mailbox. I didn't know the history, but looking at change log seems that idle as been put back to prelogin client for some kind of compatibility with their service. Anyway, the most important reason that got me to subscribe the mailing list for write those emails, is share with the community that problem and provide a solution.. for someone in the future that have the same problem and will search on internet for a solution (like I've does.. before analyze it on my own). If the workaround will be added to the wiki or will be put in the source.. the important thing is that there is a solution simple and fast (two.. the source modify, and the configuration file) and someone can find it.. (Sarcastic) And if the mayans were right we can't wait for google to fix it :p Best Regards Sent from Galaxy Nexus Robert Schetterer <rs(a)sys4.de> ha scritto: >Am 07.11.2012 08:13, schrieb Massimiliano Cianelli: >> Hello, >> >> My phone: >> Android ics 4.1.2 on galaxy nexus. >> And yes, stock mean the default client that come with the os in IMAP mode. >> >> I already know about that configuration parameter, but it will display two time namespace in postlogin capabilities, and so I like much more to adjust the source code to fix the issue. >> >> Yes there is k9 but I didn't like it too much, I prefer the stock client and is much important to keep compatibility with stock client then user-installed client. >> >> About the issue on Google code, there is thr issue on google code... but Google is a lot slow in fixing those things. >> http://code.google.com/p/android/issues/detail?id=1811 >> >> In a few hour I'll update the issue noticing where is hidden the problem. >> >> Regards >> Sent from Galaxy Nexus > >Hi , i shortly tested this with android sdk jelly bean 4.1.1 and "my >setup" dovecot 2.1.10 with included orginal android mail app in imap mode, >,leaving IMAP prefix blank, everything works as expected, no double >shown inbox, namespace problems etc >so you might have to fit your namespace setup. >Also you might follow allready given advice from here. > >Anyway , i understand you using "stock client" >but you have to understand that the producers of mail clients >optimize their stuff fitting best in their own server structure >making money with it, therefor their motivation coding better imap code >is not very high, same case is for outlook and microsoft >however, i would say, fixing bugs is on the google site here, looks like >there is patch >at >http://code.google.com/p/android/issues/detail?id=1811 >and the issue seems long known > >i dont see any hard relation to dovecot in this case >meanwhile using k9mail seems the best way to workaround >there are lots of other bugs around android versions >over the years i dont expect google to fix them > > >> >> Robert Schetterer <rs(a)sys4.de> ha scritto: >> >>> Am 06.11.2012 07:08, schrieb Ben Morrow: >>>> At 6AM +0100 on 6/11/12 you (Massimiliano Cianelli) wrote: >>>>> Hi, >>>>> >>>>> My setup: >>>>> Dovecot 2 latest, installed to replace courrier IMAP, and off course >>>>> configured with the dot separator and all folder under INBOX.*. >>>>> >>>>> The problem: >>>>> My phone was driving me mad during the test, due that it will only >>>>> recognize Inbox. >>>>> >>>>> How found the solution: >>>>> I've started sniffing IMAP traffic on my server and ended up with one >>>>> difference: >>>>> On courier it ask for namespace, on dovecot it won't. >>>>> >>>>> I gives a better look, and noticed that courier show namespace >>>>> capability on prelogin banner, adding it too solved the problem. >>>>> >>>>> Reason: >>>>> Android ICS stock client seems do not honor the capability gived after >>>>> the login. >>>> >>>> See http://wiki2.dovecot.org/Upgrading/2.0?highlight=%28capability%29 ; >>>> you need to set imap_capability and/or get your client fixed. >>>> >>>> Ben >>>> >>> >>> Hi, first ,what is the exact meaning of >>> >>> "Android ICS stock client" >>> >>> do you mean default included email client in standard android in imap >>> mode, when yes, which version of Android , i like to test my own >>> however is there changelog/code etc at google for this behave? >>> >>> conf example >>> >>> # Override the IMAP CAPABILITY response.

by tony.blue.mailinglist＠gmx.de 07 Nov '12

07 Nov '12

Hello, i use dovecot with maildir. The maildir-folder looks like this: vmail/mail/user1/cur vmail/mail/user1/.Sent vmail/mail/user1/.optionalfolder Procmail should put some definded mails in the "optionalfolder" My uses configuration does not do this: ... DELIVERMAIL="/usr/lib/dovecot/dovecot-lda" IMAP="$DELIVERMAIL -e -d $LOGNAME -m INBOX" ZUSATZORDNER="$DELIVERMAIL -e -d $LOGNAME -m .optionalfolder" ... dovecot-lda puts the mails for the optionalfolder always in the .cur (INBOX). What´s the correct dovecot-lda parameter to put the mails in the optionalfolder? Thank you! Tony

[Dovecot] acl and subfolder
by Laurent Foucher 07 Nov '12

07 Nov '12

hello, I'm using dovecot 2.0.16 and i would like to use acl for subfolder. The file dovecot-acl is well written in both folder test and the subfolder test/Test : cat /home/user2/Maildir/.test.Test/dovecot-acl user=user1 ilrws cat /home/user2/Maildir/.test/dovecot-acl user=user1 ilprws When user1 want to list, the folder test is well shown, but not the subfolder test/Test. This is the logs : Debug: acl: acl username = user1 imap(laurent.foucher): Debug: acl: owner = 0 Shuka-a dovecot: imap(user1): Debug: acl vfile: Global ACL directory: (none) Shuka-a dovecot: imap(user1): Debug: acl vfile: reading file /home/user2/Maildir/.test/dovecot-acl [....] imap(user1): Debug: acl: Mailbox not in dovecot-acl-list: Partages/user2/test/Test I don't userstand why the file dovecot-acl is not read from the subfolder, while user1 and user2 have the same gid and write access to the directories.
