Hi, after upgrading from 2.0.15 to 2.0.16 authentication with vpopmail won´t work anymore. 2.0.x and 1.2.x works (this output is from 2.0.15): Nov 28 18:29:21 mail dovecot: auth: Debug: auth client connected (pid=3855) Nov 28 18:29:21 mail dovecot: auth: Debug: client in: AUTH 1 PLAIN service=imap secured lip=10.114.57.11 rip=10.114.57.11 lport=143 rport=37693 resp=d3NjaG9lbGxlckBodGwtcGVyZy5hYy5hdAB3c2Nob2VsbGVyQGh0bC1wZXJnLmFjLmF0AGRpYWJsbw== Nov 28 18:29:21 mail dovecot: auth-worker: Debug: vpopmail(wschoeller(a)htl-perg.ac.at,10.114.57.11): lookup user=wschoeller domain=htl-perg.ac.at Nov 28 18:29:21 mail dovecot: auth: Debug: client out: OK 1 user=wschoeller(a)htl-perg.ac.at Nov 28 18:29:21 mail dovecot: auth: Debug: master in: REQUEST 4001103873 3855 1 7a21a4d39cc6b187b3b14dc4cfbf077a Nov 28 18:29:21 mail dovecot: auth-worker: Debug: vpopmail(wschoeller(a)htl-perg.ac.at,10.114.57.11): lookup user=wschoeller domain=htl-perg.ac.at Nov 28 18:29:21 mail dovecot: auth: Debug: master out: USER 4001103873 wschoeller(a)htl-perg.ac.at uid=89 gid=89 home=/var/vpopmail/domains/htl-perg.ac.at/wschoeller Nov 28 18:29:21 mail dovecot: imap-login: Login: user=<wschoeller(a)htl-perg.ac.at>, method=PLAIN, rip=10.114.57.11, lip=10.114.57.11, mpid=3856, secured Nov 28 18:29:21 mail dovecot: imap(wschoeller(a)htl-perg.ac.at): Disconnected: Logged out bytes=29/405 Nov 28 18:29:21 mail dovecot: auth: Debug: auth client connected (pid=3858) 2.0.16 doesn´t work: Nov 28 18:43:15 mail dovecot: auth: Debug: Loading modules from directory: /usr/lib/dovecot/auth Nov 28 18:43:15 mail dovecot: auth: Debug: auth client connected (pid=27392) Nov 28 18:43:15 mail dovecot: auth: Debug: client in: AUTH 1 PLAIN service=imap secured lip=10.114.57.11 rip=10.114.57.11 lport=143 rport=42768 resp=d3NjaG9lbGxlckBodGwtcGVyZy5hYy5hdAB3c2Nob2VsbGVyQGh0bC1wZXJnLmFjLmF0AGRpYWJsbw== Nov 28 18:43:15 mail dovecot: auth-worker: Debug: Loading modules from directory: /usr/lib/dovecot/auth Nov 28 18:43:15 mail dovecot: auth-worker: Debug: vpopmail(wschoeller(a)htl-perg.ac.at,10.114.57.11): lookup user=wschoeller domain=htl-perg.ac.at Nov 28 18:43:15 mail dovecot: auth-worker: vpopmail(wschoeller(a)htl-perg.ac.at,10.114.57.11): Password mismatch Nov 28 18:43:15 mail dovecot: auth-worker: Error: md5_verify(wschoeller(a)htl-perg.ac.at): Not a valid MD5-CRYPT or PLAIN-MD5 password Nov 28 18:43:15 mail dovecot: auth-worker: Error: smd5_verify(wschoeller(a)htl-perg.ac.at): SMD5 password too short Nov 28 18:43:15 mail dovecot: auth-worker: Error: ssha_verify(wschoeller(a)htl-perg.ac.at): SSHA password too short Nov 28 18:43:15 mail dovecot: auth-worker: Error: ssha256_verify(wschoeller(a)htl-perg.ac.at): SSHA256 password too short Nov 28 18:43:15 mail dovecot: auth-worker: Error: ssha512_verify(wschoeller(a)htl-perg.ac.at): SSHA512 password too short Nov 28 18:43:15 mail dovecot: auth-worker: Warning: Invalid OTP data in passdb Nov 28 18:43:15 mail dovecot: auth-worker: Debug: vpopmail(wschoeller(a)htl-perg.ac.at,10.114.57.11): CLEARTEXT(mypassword) != '', try OTP scheme instead Nov 28 18:43:17 mail dovecot: auth: Debug: client out: FAIL 1 user=wschoeller(a)htl-perg.ac.at Nov 28 18:43:17 mail dovecot: imap-login: Aborted login (auth failed, 1 attempts): user=<wschoeller(a)htl-perg.ac.at>, method=PLAIN, rip=10.114.57.11, lip=10.114.57.11, secured Dovecot -n: # 2.0.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.36-gentoo-r8 i686 Gentoo Base System release 1.12.14 auth_debug = yes auth_debug_passwords = yes disable_plaintext_auth = no first_valid_uid = 89 listen = * mail_location = maildir:~/.maildir namespace { hidden = no inbox = yes list = yes location = prefix = INBOX. separator = . type = private } passdb { args = webmail=127.0.0.1 driver = vpopmail } service auth { user = root } ssl_cert = </etc/ssl/dovecot/server.pem ssl_key = </etc/ssl/dovecot/server.key userdb { driver = vpopmail } Just a wild guess - but is it possible that the reason could be found here: http://hg.dovecot.org/dovecot-2.0/rev/b99da8b1ecef Thanks for any suggestions.

[Dovecot] squat fts not working on 2.1rc1
by Metro Domain Admin 28 Nov '11

28 Nov '11

Hello, I tried to upgrade from 2.0.15 to 2.1.rc1 over the weekend but ran into some problems with squat. My two largest mailboxes were corrupted, producing this error: Nov 27 17:38:12 kerio1 dovecot[42860]: imap(bigmailbox): Error: Corrupted squat uidlist file /var/mail/metro-email.com/bigmailbox/mdbox/mailboxes/INBOX/dbox-Mails/dovecot.index.search.uids: wrong indexid There is a good chance that I had shot my own foot, by forgetting to update postfix's dovecot-lda reference to the new instance. I had also enabled an inet based LMTP listener, although it is not being used yet. Even using non-corrupted indexes, it seemed that FTS was not being used. A basic search such as this one took many minutes to complete: doveadm search -u jsample mailbox INBOX body eps I found messages like this in mail.log after performing the search: Nov 27 18:21:39 kerio1 dovecot[42860]: indexer-worker(jsample): Indexed 0 messages in Drafts Nov 27 18:21:39 kerio1 dovecot[42860]: indexer-worker(jsample): Indexed 0 messages in INBOX When I rolled back to 2.0.15, the same search returned almost immediately. The larger mailboxes went quickly again, but only after they had a chance to rebuild. A few other notes about our configuration: We are on PPC, with the stats service disabled (because of kqueue issue discussed earlier). I made some minor changes in my config since the previous installed version (diff below). mail_location override is in place for all users via password file, e.g.: userdb_mail=mdbox:/var/mail/metro-email.com/jsample/mdbox Thanks, Tony kerio1:~ metroadmin$ /opt/dovecot-2.1.rc1/bin/doveconf -n -c /opt/dovecot-2.1.rc1/etc/dovecot/dovecot.conf # 2.1.rc1: /opt/dovecot-2.1.rc1/etc/dovecot/dovecot.conf # OS: Darwin 9.8.0 Power Macintosh auth_cache_negative_ttl = 0 auth_cache_size = 1 M auth_mechanisms = plain login lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes lmtp_proxy = yes mail_location = maildir:%h mail_plugins = fts fts_squat mail_log notify mail_privileged_group = mail maildir_very_dirty_syncs = yes managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave editheader mdbox_rotate_size = 10 M namespace { inbox = yes location = prefix = separator = / } passdb { args = scheme=CRYPT username_format=%u /opt/dovecot-2.1.rc1/etc/dovecot/users driver = passwd-file } plugin { fts = squat mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename mail_log_fields = uid box msgid size from subject sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } postmaster_address = postmaster(a)metro-email.com protocols = imap lmtp service auth { unix_listener /var/spool/postfix/private/auth { group = _postfix mode = 0660 user = _postfix } unix_listener auth-userdb { group = mail mode = 0660 user = metroadmin } } service imap { executable = imap postlogin } service lmtp { inet_listener lmtp { address = 192.168.20.10 127.0.0.1 port = 24 } } service postlogin { executable = script-login rawlog -t } service stats { fifo_listener stats-mail { mode = 00 } } ssl_cert = </opt/local/apache2/conf/ssl_startcom/server.crt ssl_key = </opt/local/apache2/conf/ssl_startcom/server.key userdb { args = username_format=%u /opt/dovecot-2.1.rc1/etc/dovecot/users driver = passwd-file } verbose_proctitle = yes protocol imap { mail_max_userip_connections = 16 } Here is a diff between the current/working and attempted configs: kerio1:~ metroadmin$ diff k1.curr k1.new2 1c1 < # 2.0.15: /opt/dovecot-2.0.15/etc/dovecot/dovecot.conf --- > # 2.1.rc1: /opt/dovecot-2.1.rc1/etc/dovecot/dovecot.conf 9a10 > lmtp_proxy = yes 15c16 < managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave --- > managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave editheader 24c25 < args = scheme=CRYPT username_format=%u /opt/dovecot-2.0.15/etc/dovecot/users --- > args = scheme=CRYPT username_format=%u /opt/dovecot-2.1.rc1/etc/dovecot/users 50a52,57 > service lmtp { > inet_listener lmtp { > address = 192.168.20.10 127.0.0.1 > port = 24 > } > } 53a61,65 > service stats { > fifo_listener stats-mail { > mode = 00 > } > } 57c69 < args = username_format=%u /opt/dovecot-2.0.15/etc/dovecot/users --- > args = username_format=%u /opt/dovecot-2.1.rc1/etc/dovecot/users kerio1:~ metroadmin$

[Dovecot] Which FTS to use!
by Henrique Santos Fernandes 27 Nov '11

27 Nov '11

Hello, i am currently using squat dovecot, but some users that have lots os emails ( 1GB ) are complaining about speed. Iam using dovecot 2.0.13 on debian 6 my squat conf is plugin { fts = squat fts_squat = partial=4 full=5 } I am thinking in maybe start to use Solr, so any one can help me with an decision? I am probably gonna update dovecot to 2.1 next year. and them maybe change the FTS plugin. This year i will get 10k disk only to store the dovecot index, rigth now they are saved on the same storage that the mails are and also change the "full" parameter to something like 10 or 15 I know i will use more disk space for it, but it will make a lot of differences right? it will match the message without the need of opening it for any search smaller than 10 character i guess. But this will be enough? or Solr or Lucene still better? Anyway, i am not current updating the indexes automatic, but i am planing on it, just not sure what is better, the command doveadm index or doveadm search... with one is better to do the task? Thanks! []'sf.rique

[Dovecot] Seen flag getting lost
by Edgar Fuß 26 Nov '11

26 Nov '11

We have two dovecot 1.2 instances sharing Maildirs on NFS. Indexes are local to the individual servers. Occasionally (no idea how to trigger this), the Seen flag gets lost on some messages. I've verified that actually the ``S'' is missing from the filename. I suspect something like server A caching the flags, server B setting Seen, and then server A flushing its cache for another change so overwriting what B changed. Any ideas short of switching to 2.0?

[Dovecot] v2.1.rc1 released
by Timo Sirainen 25 Nov '11

25 Nov '11

http://dovecot.org/releases/2.1/rc/dovecot-2.1.rc1.tar.gz http://dovecot.org/releases/2.1/rc/dovecot-2.1.rc1.tar.gz.sig I'll probably release v2.1.0 pretty soon, unless people report some new bugs. I know v2.1 is already being used to serve mails to tens (or hundreds?) of thousands of users, so it should be pretty stable. Most of the changes since v2.1.beta1 have been for rather small issues. Many of the fixed bugs exist also in v2.0, but since they are so minor I didn't bother backporting the fixes. As new features since v2.1.beta1 there are the things I did also for v2.0.16, and: * ssl_client_cert/key: Proxying can now send SSL certificate to backend server * ssl_crypto_device for enabling hardware encryption * SCRAM-SHA-1 authentication mechanism support by Florian Zeitz * passdb/userdb checkpassword: Export all auth %variables to AUTH_* environment. * maildir_broken_filename_sizes setting for people upgrading from other maildir servers that wrote tons of broken S=<size> values And as a reminder, here are the biggest new things since v2.0: * Plugins now use UTF-8 mailbox names rather than mUTF-7: acl, autocreate, expire, trash, virtual * auth_username_format default changed to %Lu. If you really want case sensitive usernames, set it back to empty. * Solr full text search backend changed to use mailbox GUIDs instead of mailbox names, requiring reindexing everything. solr_old backend can be used with old indexes to avoid reindexing, but it doesn't support some newer features. + imapc (= IMAP client) storage allows using a remote IMAP server to be used as storage. This allows using Dovecot as a smart (caching) proxy or using dsync to do migration from remote IMAP server. + Mailbox indexing via queuing indexer service (required for Lucene) + Lucene full text search (FTS) backend rewritten with support for different languages + FTS finally supports "OR" search operation + FTS supports indexing attachments via external programs + IMAP FUZZY extension, supported by Lucene and Solr FTS backends + Mailbox list indexes + Statistics tracking via stats service. Exported via doveadm stats. + Autocreate plugin creates/subscribes mailboxes physically only when the mailbox is opened for the first time. Mailbox listing shows the autocreated mailboxes even if they don't physically exist. + Password and user databases now support default_fields and override_fields settings to specify template defaults/overrides. - listescape plugin works perfectly now

[Dovecot] How to create home directories for virtual users?
by Olli Räisänen 25 Nov '11

25 Nov '11

Hello, I,m using Dovecot 1.2.9, now finishing a migration from Courier IMAP. Documentation (http://wiki.dovecot.org/VirtualUsers/Home) says that home directory should not be the same as mail directory. When I create new user accounts with PostfixAdmin the mail directory is not a problem but is there some smart way to create the home directory as well (locating it for instance in '/srv/vmail/%d/%n/home')? Regards, Olli

[Dovecot] Problem with lmtp proxy
by Miguel Tormo 24 Nov '11

24 Nov '11

Hello everyone, I have set up postfix to deliver mails to dovecot (2.0.16) using LMTP. On the other hand, I've successfully configured the IMAP proxy setting in dovecot in order to be able to distribute mailboxes among different servers. I wanted to do the same proxy at LMTP level, but it's not working. If I put lmtp_proxy = no, then everything works ok (assuming the mailbox is local), but when I set lmtp_proxy = yes then the user is not found when deliverying the message via LMTP, so the mail remains in the postfix queue. Users are validated through active directory. However, this AD hasn't the SFU installed, thus its LDAP schema doesn't provide me with the required uid, gid, etc. To solve this, I have winbind configured in the system, so I'm doing this: - To validate users *and* be able to set the proxy extra fields, I use ldap as "passdb" (I believe it's not possible to use proxies with PAM). I'm using some LDAP field to store the host that has the user's mailbox. - In order to get the user account data that is not available in the AD, I use passwd as "userdb". I know that when using LMTP with proxy, a passdb needs to be configured. I assume this is needed for the service to lookup for the appropriate host to send the message. So, initially I set ldap as the passdb for LMTP, but just because it didn't work I put both ldap and passwd, and even a userdb (passwd), but the problems remain the same. Anyway the ldap should be the right one as it is there where I have the host information for each user. I think I'm missing something but I can't find what it is. To summarize: with lmtp_proxy = no it does work, with lmtp_proxy = yes it doesn't. Thank you for your help!

[Dovecot] modules directory
by Johannes Berg 24 Nov '11

24 Nov '11

Hi! I'm a little confused with how plugin loading works in dovecot 2, I can't seem to make it load from $(moduledir)/imap/. Is that intended to work? Just a configuration issue? Reason I ask is that I ported my antispam plugin (I know there's a fork, but I still like mine better) to dovecot 2 and the default "make install" no longer loads properly with just "mail_plugins = antispam". So is $(moduledir)/imap/ no longer used? I also notice acl/imap_acl now, but I still see subdirectories for at least auth. Should I install into just $(moduledir)/ now? johannes

Re: [Dovecot] Solaris hardware crypto engines
by Martin Preen 24 Nov '11

24 Nov '11

Hello, after serveral tests (and reading a lot of howto's) I'm now fairly convinced that the Solaris HW-crypto engine is not automatically used. Even when dovecot ist compiled with the OpenSSL version provided by Solaris. Currently I have only a T1-CPU available for testing (Sun Fire T2000) and after patching src/login-common/ssl-proxy-openssl.c (Dovecot 1.2.17) with ENGINE *e; ENGINE_load_builtin_engines(); ENGINE_init((e=ENGINE_by_id("pkcs11"))); ENGINE_set_default_RSA(e); ENGINE_set_default_DSA(e); ENGINE_set_default_ciphers(e); in ssl_proxy_init() and inserting ENGINE_cleanup(); in ssl_proxy_deinit() the crypto device gets used. I'm sure that this is not the whole story since this only seems to affect the IMAP login. One has to use the specific SSL-engine and the ENGINE/EVP calls (as stated in the various articles). Is there any chance that Dovecot gets updated/patched for this ? E.g. Like the SSLCryptoDevice setting in Apache's mod_ssl. Regards.

[Dovecot] seting acl for master user?
by oni-neko＠gmx.net 24 Nov '11

24 Nov '11

Hello! I'm sorry, but i don't really understand it the way it is written in the wiki, so i'm trying my luck here =) i followed the wiki for creating a master user (the non-sql-version) and i can login as another user via this master user. my dovecot version is 1.2.9 on an ubuntu server 10.4.3 lts. what i don't get is the acl-setting, so that the master-user can access all the other users mails and folders. i made the changes in the dovecot.conf as written in the wiki: protocol imap { mail_plugins = acl imap_acl } protocol lda { mail_plugins = sieve acl } plugin { acl = vfile:/etc/dovecot/acls } in my case I only want the master user (called cyrus) to be able to do everything with/in all mailboxes, so I made a file /etc/dovecot/acls/default that reads "user=cyrus lrwstipekxa". i'm pretty sure i'm missing something rather obvious here, but somehow i'm just stuck. any help would be greatly appreciated. thanks in advance =) silvana -- NEU: FreePhone - 0ct/min Handyspartarif mit Geld-zurück-Garantie!

[Dovecot] Random Loss of Connection with Thunderbird and Dovecot
by Jay Welch 24 Nov '11

24 Nov '11

Hi, Dovecot Version: 1.2.16 OS: CENTOS 5.5 I am having issues with Thunderbird connecting to Dovecot at random times. Usually an error comes up and states that Thunderbird cannot connect to the server. The only way I have been able to fix this is reset/repair the network connection or reboot the computer. Is there any parameters I can change in Dovecot to fix this issue? Does anyone know what is likely going on? I have been reading forums and I cannot find anything. Thanks

[Dovecot] Excluding some system users after configuration
by Nanitous 24 Nov '11

24 Nov '11

Dear readers, Consider an installed Postfix configuration (2.3.3) on CentOS. Now I want to install Dovecot (alas only version 1.0.7.7 is available) to provide IMAP services for a few system users, but not all. Most importantly the mail delivery by postfix for some of these system user /must/ not change after the installation of Dovecot. How can I prevent the installation of Dovecot to touch some specific system user accounts? Thanks in advance, /Twan

[Dovecot] How to disable pop3 in version 2?
by Knute Johnson 24 Nov '11

24 Nov '11

I'm about to bring up a new mail server running Ubuntu 11.10 with Dovecot 2. I've been using 1.2 all along and there are a bunch more config files in 2. In 1.2 I just edited the protocols statement but I can't find one in version 2. Is there a way to disable pop3 or do I just firewall the ports? And a related question, I've been using imaps on port 993 but I hear that's not the best solution anymore, I should be using imap with STARTTLS? How do I disable imaps? Thanks, -- Knute Johnson

[Dovecot] 1.2.15 can't get zlib working
by Stan Hoeppner 24 Nov '11

24 Nov '11

Following these instructions: http://wiki.dovecot.org/Plugins/Zlib I enabled zlib and restarted Dovecot. I made a backup copy of a 68MB mbox file and moved it to a non mail directory. The mbox file is an existing TBird IMAP folder in my UNIX user mail directory. It is an archive of a defunct mailing list. It was a regular IMAP folder prior to attempting this. I was able to access all emails in the folder. It worked fine. I gzipped the original mbox file down to 14MB and removed the write flag with chmod. I launched TBird and received the following error in Activity Manager when accessing this IMAP folder: The current operation on '1-Spam-l' did not succeed. The mail server for account stan(a)hardwarefreak.com responded: Mailbox doesn't exist: 1-Spam-l I deleted the Dovecot index files and the TBird 1-Spam-l.msf file which didn't help. Curiously, there are no entries in either dovecot.err or dovecot.log, giving not even the slightest hint as to where I should troubleshoot. Kinda sucks when one follows instructions exactly, simple instructions at that, and it doesn't work, and generates zero log errors. A bit frustrating...

[Dovecot] v2.1.beta1 released
by Timo Sirainen 23 Nov '11

23 Nov '11

http://dovecot.org/releases/2.1/beta/dovecot-2.1.beta1.tar.gz http://dovecot.org/releases/2.1/beta/dovecot-2.1.beta1.tar.gz.sig Here's the first beta release of Dovecot v2.1. This version has already been tested quite a lot, so I'm not expecting any major bugs. So please upgrade and see if you can find any problems. I'm optimistic about getting rc1 released this year and perhaps even v2.1.0. Since alpha2 there have been a lot of fixes, especially to imapc backend. There are probably also some small new features, but nothing huge. As a reminder, here's the largest changes since v2.0: * Plugins now use UTF-8 mailbox names rather than mUTF-7: acl, autocreate, expire, trash, virtual * auth_username_format default changed to %Lu. If you really want case sensitive usernames, set it back to empty. * Solr full text search backend changed to use mailbox GUIDs instead of mailbox names, requiring reindexing everything. solr_old backend can be used with old indexes to avoid reindexing, but it doesn't support some newer features. + imapc (= IMAP client) storage allows using a remote IMAP server to be used as storage. This allows using Dovecot as a smart (caching) proxy or using dsync to do migration from remote IMAP server. + Mailbox indexing via queuing indexer service (required for Lucene) + Lucene full text search (FTS) backend rewritten with support for different languages + FTS finally supports "OR" search operation + FTS supports indexing attachments via external programs + IMAP FUZZY extension, supported by Lucene and Solr FTS backends + Mailbox list indexes + Statistics tracking via stats service. Exported via doveadm stats. + Autocreate plugin creates/subscribes mailboxes physically only when the mailbox is opened for the first time. Mailbox listing shows the autocreated mailboxes even if they don't physically exist. + Password and user databases now support default_fields and override_fields settings to specify template defaults/overrides. - listescape plugin works perfectly now

[Dovecot] dovecot as an imap "client"
by David LEROUX 23 Nov '11

23 Nov '11

Hi, I need to get emails from one of my users imap account on a server which is not managed by us to his local imap mailbox. I'm almost sure that I've read some times that dovecot would be able to do that, kind of imap relay, but I can't find it again. I'm not sure to be very clear. Thanks, -- David

[Dovecot] [PATCH] SCRAM-SHA-1 authentication
by Florian Zeitz 23 Nov '11

23 Nov '11

Hy, over the last days I have implemented SCRAM-SHA-1 in Dovecot's 2.1 branch. It does not do SCRAM-SHA-1-PLUS, but should be extendable enough to introduce it later. There are some checks for the message format which (assuming the client acts correclty) are not strictly necessary during parsing. This is partially in the hope that it might aid client implementers, partially because it (IMHO) improves readability when checking against the RFC. Also errors found in this way could be sent to the client, this is however strictly OPTIONAL in the RFC, for now they are just logged. Some of the variable names are rather long. This is in order to have them match the terms introduced in the RFC, again I expect it to help readability (maybe my recent Objective-C programming showing though). I do feel somewhat insecure about my usage of some lib functions. Hopefully no API has been abused too much. I also note that there are a lot of fields in the scram_auth_request struct. I think they are all there for a reason, however feel free to prove me wrong. Attached is a hg export. It also includes a hmac-sha1 implementation, an adaption off of the hmac-md5 implementation already in Dovecot. I guess those should eventually be merged into a hash-independent hmac implementation, but I figured this would have to do for now. The implementation has been tested against GNU SASL and does appear to work fine. (The command line was `gsasl -m SCRAM-SHA-1 -a user -p pass --imap host` for those curious) Regards Florian "Florob" Zeitz

[Dovecot] Can't delete sub-folder
by pch0317 23 Nov '11

23 Nov '11

Hi list, I have problem with deleting sub-folder. I use thunderbird 8.0 as a client and dovecot 2.0.9 with imap protocol as a server. I use dovecot with tb-extra-mailbox-sep parameter. I use mbox mailboxes and thunderbird with *not checked* option 'server supports folders that contain sub-folders and messages' so when I create sub-folder I can choose between 'folders only' and 'messages only'. When I try to delete 'parent' folder which contain 'messages only' folder, error message appear: [ALREADYEXISTS] Mailbox has children, delete them first. Ok, so I delete 'message only' folder first and try to delete parent folder, but the same error appear: [ALREADYEXISTS] Mailbox has children, delete them first. When I list mailboxes from console I see inside 'parent' folder ".imap" folder. When I delete .imap folder from console and then delete parent folder from thunderbird, parent folder is deleted correctly. Which application create this ".imap" hidden folder and how solve this problem. Thanks
