Everything costs less than a NetApp...except an EMC. > If anyone has any first-hand experience (or even > off-the-top-of-their-head thoughts), I'd love to hear them) Distributed filesystems give you the advantage of a single filesystem namespace with massive amounts of storage, fairly easy addition of storage space, and distributed replication to allow failure of a storage node without service interruption. Replication mitigates node failure, but not disk failure, so you still need RAID in each node. So you have RAID6 in a node and filesystem block mirroring amongst nodes. Thus storage utilization is -worse- than direct attach, CFS on SAN, or NFS head attached RAID10 and far worse than RAID6 in these 3 setups. And if using large SSD cache you'd surely use RAID6 with DAS, CFS, or NFS. You'd need half as many disk drives vs DFS. Each DFS expansion, assuming the typical model, entails the cost of a server, RAID HBA (unless using md) and disks, not strictly buying disks as with DAS, CFS/SAN, or NFS filer. Then you also need more switch ports, more power connections, greater UPS capacity due to all the CPUs, RAM, etc in the nodes. And you'll have a higher electric bill. So while a distributed filesystem storage architecture may seem less expensive it may not be. And just as one can build a DIY DFS cluster, one can also build a DIY NFS cluster instead of buying a NetApp, saving significant cash on the front end box and on disks since you'd need half as many vs a distributed filesystem architecture, though failure of one node may not be quite as graceful as with a NetApp losing a controller board. -- Stan

[Dovecot] Replication - what am I doing wrong?
by IT geek 31 27 Jan '14

27 Jan '14

Hi, I'm having issues getting replication working, and I'm not also not having much luck finding help on it. So I'm wondering... am I not asking the right questions? Or am I not providing enough information... or do we just not know how this aspect of the technology works? If it's the former, then any pointers on what questions to ask or information to provide would be very helpful. If the community genuinely doesn't know how this works then that's okay too - I will look at another solution (if one exists) and try to move on. But if I can get this working then that would be amazing as I really like Dovecot and would be gutted to move away from it. -Mark

[Dovecot] managesieve - point me in the right direction?
by erik 27 Jan '14

27 Jan '14

Hi, I am using Dovecot 2.1.16. I'm trying to get Roundcube to talk to the managesieve plugin. Postfix/Dovecot/Roundcube all exist on the same server. I'd like to get managesieve working. I've gone through a few guides, such as: https://wiki.archlinux.org/index.php/dovecot#Sieve But so far roundcube won't connect to the managesieve plugin. ("Cant reach server"). I see that port 4190 is listening and I can telnet to that port: Connected to localhost. Escape character is '^]'.

I'm not sure what else to check. Any help appreciated!

Hey guys, i have a weird problem i'm trying to fix since 5 months now, but i really couldn't find any explanation, why this happens and how it can be fixed. My client is Thunderbird, my dovecot version is 2.1.7-7 from the official Debian repo. If you want to see my config i'll grab all the fils together and send it to you. This is the error i'm always getting when my client tries to get new mails, which i want to get rid off: http://sprunge.us/NZhf Jan 25 11:49:30 old dovecot: auth-worker(15979): Debug: sql(root(a)hallowe.lt,81.217.212.85): query: SELECT password FROM mailbox WHERE username = 'root(a)hallowe.lt' Jan 25 11:49:30 old dovecot: auth: Debug: client out: OK#0111#011user=root(a)hallowe.lt Jan 25 11:49:30 old dovecot: auth-worker(15979): Debug: sql(root(a)hallowe.lt,81.217.212.85): SELECT CONCAT('maildir:/var/vmail/',maildir) AS mail, 1000 AS uid, 1000 AS gid FROM mailbox WHERE username = 'root(a)hallowe.lt' Jan 25 11:49:30 old dovecot: auth: Debug: master out: USER#0113983671297#011root@hallowe.lt#011mail=maildir:/var/vmail/hallowe.lt/root/#011uid=1000#011gid=1000 Jan 25 11:49:30 old dovecot: imap-login: Login: user=<root(a)hallowe.lt>, method=PLAIN, rip=81.217.212.85, lip=10.111.56.107, mpid=17606, TLS, session=<rQGqOsnwuABR2dRV> Jan 25 11:49:30 old dovecot: imap(root(a)hallowe.lt): Debug: Effective uid=1000, gid=1000, home= Jan 25 11:49:30 old dovecot: imap(root(a)hallowe.lt): Debug: quota: No quota setting - plugin disabled Jan 25 11:49:30 old dovecot: imap(root(a)hallowe.lt): Debug: maildir++: root=/var/vmail/hallowe.lt/root, index=, control=, inbox=/var/vmail/hallowe.lt/root, alt= Jan 25 11:49:30 old dovecot: imap(root(a)hallowe.lt): Panic: file index-mailbox-check.c: line 75 (index_mailbox_check_add): assertion failed: (box->notify_min_interval > 0) Jan 25 11:49:30 old dovecot: imap(root(a)hallowe.lt): Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(+0x4414a) [0x7f858118714a] -> /usr/lib/dovecot/libdovecot.so.0(+0x4418e) [0x7f858118718e] -> /usr/lib/dovecot/libdovecot.so.0(i_fatal+0) [0x7f858115e82a] -> /usr/lib/dovecot/libdovecot-storage.so.0(+0x99027) [0x7f858146b027] -> /usr/lib/dovecot/libdovecot-storage.so.0(+0x4ccc9) [0x7f858141ecc9] -> dovecot/imap(cmd_idle+0x66) [0x7f8581907c96] -> dovecot/imap(command_exec+0x3c) [0x7f858190dedc] -> dovecot/imap(+0x11f2e) [0x7f858190cf2e] -> dovecot/imap(+0x11fda) [0x7f858190cfda] -> dovecot/imap(client_handle_input+0x11d) [0x7f858190d23d] -> dovecot/imap(client_input+0x65) [0x7f858190db35] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x36) [0x7f8581194016] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0xa7) [0x7f8581194cc7] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_run+0x28) [0x7f8581193a28] -> /usr/lib/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7f8581180483] -> dovecot/imap(main+0x297) [0x7f85819053e7] -> /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xfd) [0x7f8580dd7ead] -> dovecot/imap(+0xa561) [0x7f8581905561] Jan 25 11:49:30 old dovecot: imap(root(a)hallowe.lt): Fatal: master: service(imap): child 17606 killed with signal 6 (core dumps disabled) I asked for this in the irc already but got no answer.

[Dovecot] outlook will not sync
by Eric Broch 27 Jan '14

27 Jan '14

Dovecot users list, I started having problems with Outlook not syncing with Dovecot a public imap folder upon issuing a send/receive in the client; eventually Outlook timed out, and I received the following error in the Dovecot log. Jan 23 09:20:23 imap(user(a)mydom.com): Error: FETCH [] for mailbox projects.myfolder UID 120 got too little data: 7744 vs 7759 Jan 23 09:20:23 imap(user(a)mydom.com): Error: Maildir filename has wrong W value: /home/vpopmail/domains/mydom.com/shared/projects/.myfolder/cur/1384292337.M440452P9788.mail.mydom.com,S=265901,W=269597:2,Sc Jan 23 09:20:23 imap(user(a)mydom.com): Error: Corrupted index cache file /home/vpopmail/domains/mydom.com/shared/projects/.myfolder/dovecot.index.cache: Broken virtual size for mail UID 120 Jan 23 09:20:23 imap(user@mydom): Info: Disconnected: FETCH failed bytes=175/270387 However, I've since removed the file manually, deleted the old folder and recreated it and Outlook will still not sync even in the absence of the above error. Has anyone seen this issue--slow to no Outlook performance with dovecot--before, and/or does anyone have a solution or point me in the right direction? Thanks!

[Dovecot] dovecot produces messages dupes after nfs problems
by Patrick Westenberg 25 Jan '14

25 Jan '14

Hi everyone, some days ago I had trouble with my NFS-Server (high delays) which caused dovecot lmtp to deliver the same message several times (up to 10x). I recognized some old/unused .nfsXXXX files in the maildirs which seemed to be index files. I deleted them and everything was fine again. However, there are still 2-3 mailboxen where mails (old and new ones) are delivered multiple times. All duplicates have no "received from" headers. Seperate lmtp log shows only one delivery.

[Dovecot] Architecture for large Dovecot cluster
by Murray Trainer 25 Jan '14

25 Jan '14

Hi All, I am trying to determine whether a mail server cluster based on Dovecot will be capable of supporting 500,000+ mailboxes with about 50,000 IMAP and 5000 active POP3 connections. I have looked at the Dovecot clustering suggestions here: http://blog.dovecot.org/2012/02/dovecot-clustering-with-dsync-based.html and some other Dovecot mailing list threads but I am not sure how many users such a setup will handle. I have a concern about the I/O performance of NFS in the suggested architecture above. One possible option available to us is to split up the mailboxes over multiple clusters with subsets of domains. Is there anyone out there currently running this many users on a Dovecot based mail cluster? Some suggestions or advice on the best way to go would be greatly appreciated. Thanks Murray

hi, i tried to setup my configuration to use the SETQUOTA command but the only thing i got is: 3 setquota "User quota" (storage 12345) 3 OK Setquota completed. but nothing is changed in database. i modified the password_query and the user_query to return the admin and userdb_admin field, both set to y. all other changes that are done are like in the wiki http://wiki2.dovecot.org/Quota/Configuration enabling debug doesn't show anything in debug.log

[Dovecot] Dovecot imap-postlogin failed
by Sayajin 24 Jan '14

24 Jan '14

*** This is 2 posts combined into one which I had asked on linuxquestions.org and never got an answer *** Hi, In short I am trying to run a bash script which will then update a mysql database with the last login date/time & last IP for each mailbox. I have searched google dead but still cant figure out what im doing wrong or if there is some issue with the centos 6 rpm's for dovecot. -- - 1st i had the default dovecot in the centos 6 repo's which is version: 2.0.9 - I read that there was an issue with the script-login binary which was fixed in version 2.0.14, so i updated dovecot to version 2.2.7. - This sadly did not fix my issue with the bash script excecuting. In my /etc/dovecot/conf.d/10-master.conf i have the following service imap { executable = imap imap-postlogin } service imap-postlogin { executable = script-login /var/www/lighttpd/mail-admin/scripts/lastLogin.sh } But when i try login i still get the same error as with the previous version: - Nov 27 14:44:36 dovecot: imap(MaIlBoX(a)DoMaIn.co.za): Error: net_connect_unix(/var/run/dovecot/imap-postlogin) failed: No such file or directory - One thing i did notice on the one site was that someone had a ls of their /var/run/dovecot directory, and in there was a binary called imap-postlogin. - But i dont have that binary anywhere on my server, with the old or new version of dovecot. Please any help would be appreciated. ===================================================== ===================================================== Ok well i tried a few other things and got it working a bit more.

[Dovecot] Writing an FTS plugin
by John Morrissey 23 Jan '14

23 Jan '14

Hi, I'm having some trouble writing an FTS plugin that uses notmuch (http://notmuchmail.org/) as the backend. As a proof of concept, I'm adding a hardcoded UID to the search results in the plugin's lookup handler: seq_range_array_add(&result->definite_uids, 1, 42); but this UID is never returned by IMAP SEARCH commands. I know the plugin is being used, since I'm also syslogging immediately before the call to seq_range_array_add(). Interestingly, SEARCH commands return correct results (based on the mailbox content and the search terms specified), but I'm not sure where those results are coming from. The notmuch plugin is the only configured FTS plugin: mail_plugins = $mail_plugins fts fts_notmuch plugin { fts = notmuch } What might I be doing wrong? Additionally, notmuch returns message filenames, which I'll need to translate to UIDs. I've seen maildir_uidlist_get_uid(), but I'm not sure where to get the struct maildir_uidlist arg it needs. notmuch only supports the Maildir format, so using a maildir_* function seems a reasonably safe assumption, but is there a better way? john -- John Morrissey _o /\ ---- __o jwm(a)horde.net _-< \_ / \ ---- < \, www.horde.net/ __(_)/_(_)________/ \_______(_) /_(_)__

[Dovecot] Problem with LDA. When vacation auto-reply sent, the field from=<>.
by Dmitry 23 Jan '14

23 Jan '14

Hi, My problem is that when vacation auto-reply sent the field from=<> Because of this does not work "sender_dependent_relayhost_maps" in postfix. My scheme is: There are several postfix on different machines 1.1.1.1 - domain1 2.2.2.2 - domain2 3.3.3.3 - domain3 All they send messages to one server virtual_transport = lmtp:10.10.10.10:24 where mail is stored. In 10.10.10.10 installed dovecot 2.2.9, dovecot-pigeonhole 0.4.2 and another posfix In postfix inet_interfaces = 10.10.10.10 sender_dependent_relayhost_maps = hash:$config_directory/relayhost_maps relayhost_maps @domain1 [1.1.1.1] @domain2 [2.2.2.2] @domain3 [3.3.3.3] Sieve script make from Roundcube require ["vacation"]; # rule:[autoreply] if true { vacation :days 1 :subject "Test." "Test."; } (if add [":from" string] nothing changes) The letter comes, script fulfills, vacation auto-reply sent. But either /usr/sbin/sendmail -i -f <> -- user@senddomain or, if write in 15-lda.conf submission_host = 10.10.10.10:25 postfix log Jan 1 00:00:00 mail pf-OUT/cleanup[6098]: 4CD104A8A4: message-id=<dovecot-sieve-1390316174-295666-0@mail> Jan 1 00:00:00 mail pf-OUT/qmgr[5950]: 4CD104A8A4: from=<>, size=693, nrcpt=1 (queue active) How to make dovecot and dovecot-pigeonhole write in field MAIL FROM:?

[Dovecot] IDLE dropping EXISTS events on mass message arrival
by Eric Wong 22 Jan '14

22 Jan '14

Hi, I'm not sure if this is some throttling/DoS protection or a bug. I didn't see notice anything like it mentioned looking at the NEWS file from hg, this is on 2.1.7 on Debian stable. I have a client doing IDLE on INBOX.vomiteer. When individual messages arrive with some time interval in between them, I get EXISTS events for each message as expected. However, when I store a bunch of messages at once (via tag + mass copy in mutt on a fast-ish connection), I get a few EXISTS events (sometimes one, sometimes two) even though I copied a lot of new messages over. I expected to get an EXISTS event for each message which arrived, but perhaps there's some sort of DoS/throttling mechanism. strace -t -s4096 output of the dovecot process below: fd=13 is inotify, you'll see large read(13, ... indicating multiple filenames from inotify. However, only one EXISTS message got written to the socket. I've filtered out the gettimeofday syscalls for brevity. 07:30:02 epoll_wait(9, {}, 6, 3937) = 0 07:30:06 stat64("/home/ew/.maildir/.INBOX.vomiteer/cur", {st_mode=S_IFDIR|0700, st_size=12288, ...}) = 0 07:30:06 stat64("/home/ew/.maildir/.INBOX.vomiteer/new", {st_mode=S_IFDIR|0700, st_size=4096, ...}) = 0 07:30:06 stat64("/home/ew/.maildir/.INBOX.vomiteer/new", {st_mode=S_IFDIR|0700, st_size=4096, ...}) = 0 07:30:06 stat64("/home/ew/.maildir/.INBOX.vomiteer/cur", {st_mode=S_IFDIR|0700, st_size=12288, ...}) = 0 07:30:06 stat64("/home/ew/.maildir/.INBOX.vomiteer/dovecot.index.log", {st_mode=S_IFREG|0600, st_size=25920, ...}) = 0 07:30:06 fstat64(10, {st_mode=S_IFREG|0600, st_size=25920, ...}) = 0 07:30:06 epoll_wait(9, {}, 6, 7865) = 0 07:30:14 setsockopt(11, SOL_TCP, TCP_CORK, [1], 4) = 0 07:30:14 write(11, "* OK Still here\r\n", 17) = 17 07:30:14 setsockopt(11, SOL_TCP, TCP_CORK, [0], 4) = 0 07:30:14 time(NULL) = 1390289414 07:30:14 epoll_wait(9, {{EPOLLIN, {u32=4159555408, u64=4159555408}}}, 6, 22124) = 1 07:30:17 read(13, "\2\0\0\0\200\0\0\0\t\365\r\0000\0\0\0001390289417.M94623P14841.dcvr,S=1580,W=1619:2,S\0\0\2\0\0\0\200\0\0\0\n\365\r\0000\0\0\0001390289417.M94624P14841.dcvr,S=1580,W=1619:2,S\0\0\2\0\0\0\200\0\0\0\v\365\r\0000\0\0\0001390289417.M94625P14841.dcvr,S=1422,W=1460:2,S\0\0\2\0\0\0\200\0\0\0\f\365\r\0000\0\0\0001390289417.M94626P14841.dcvr,S=1422,W=1460:2,S\0\0\2\0\0\0\200\0\0\0\r\365\r\0000\0\0\0001390289417.M94627P14841.dcvr,S=1861,W=1907:2,S\0\0\2\0\0\0\200\0\0\0\16\365\r\0000\0\0\0001390289417.M94628P14841.dcvr,S=1861,W=1907:2,S\0\0\2\0\0\0\200\0\0\0\17\365\r\0000\0\0\0001390289417.M94629P14841.dcvr,S=4732,W=4854:2,S\0\0\2\0\0\0\200\0\0\0\20\365\r\0000\0\0\0001390289417.M94630P14841.dcvr,S=4732,W=4854:2,S\0\0\2\0\0\0\200\0\0\0\21\365\r\0000\0\0\0001390289417.M94631P14841.dcvr,S=4028,W=4128:2,S\0\0\2\0\0\0\200\0\0\0\22\365\r\0000\0\0\0001390289417.M94632P14841.dcvr,S=4028,W=4128:2,S\0\0\2\0\0\0\200\0\0\0\23\365\r\0000\0\0\0001390289417.M94633P14841.dcvr,S=3865,W=3968:2,S\0\0\2\0\0\0\200\0\0\0\24\365\r\0000\0\0\0001390289417.M94634P14841.dcvr,S=3865,W=3968:2,S\0\0", 32768) = 768 07:30:17 epoll_wait(9, {{EPOLLIN, {u32=4159555408, u64=4159555408}}}, 6, 499) = 1 07:30:17 read(13, "\2\0\0\0\200\0\0\0\25\365\r\0000\0\0\0001390289417.M94635P14841.dcvr,S=4092,W=4189:2,S\0\0\2\0\0\0\200\0\0\0\26\365\r\0000\0\0\0001390289417.M94636P14841.dcvr,S=4092,W=4189:2,S\0\0\2\0\0\0\200\0\0\0\27\365\r\0000\0\0\0001390289417.M94637P14841.dcvr,S=1517,W=1552:2,S\0\0\2\0\0\0\200\0\0\0\30\365\r\0000\0\0\0001390289417.M94638P14841.dcvr,S=1517,W=1552:2,S\0\0", 32768) = 256 07:30:17 epoll_wait(9, {}, 6, 498) = 0 07:30:17 stat64("/home/ew/.maildir/.INBOX.vomiteer/new", {st_mode=S_IFDIR|0700, st_size=4096, ...}) = 0 07:30:17 stat64("/home/ew/.maildir/.INBOX.vomiteer/cur", {st_mode=S_IFDIR|0700, st_size=12288, ...}) = 0 07:30:17 stat64("/home/ew/.maildir/.INBOX.vomiteer/dovecot.index.log", {st_mode=S_IFREG|0600, st_size=26328, ...}) = 0 07:30:17 fstat64(10, {st_mode=S_IFREG|0600, st_size=26328, ...}) = 0 07:30:17 pread64(10, "\200\200\200\207@\0\0\20\0\0\0\0\0\0\0\0$\0\0\0\0\0\0\0\1\0\0\0\200\200\200\214\0\1\0\20\0\0$\0\337!\336R\344\231\2L\0\0\0\0\t\"\336R\t\"\336R\0\0\0\0\t\"\336R\0\0\0\0007\n\0\0\200\200\200\204 \0\0\20@\0\4\0\234e\0\0\200\200\200\242\2\0\0\20\317\0\0\0\10\0\0\0\320\0\0\0\10\0\0\0\321\0\0\0\10\0\0\0\322\0\0\0\10\0\0\0\323\0\0\0\10\0\0\0\324\0\0\0\10\0\0\0\325\0\0\0\10\0\0\0\326\0\0\0\10\0\0\0\327\0\0\0\10\0\0\0\330\0\0\0\10\0\0\0\331\0\0\0\10\0\0\0\332\0\0\0\10\0\0\0\333\0\0\0\10\0\0\0\334\0\0\0\10\0\0\0\335\0\0\0\10\0\0\0\336\0\0\0\10\0\0\0\200\200\200\207@\0\0\20\1\0\0\0\0\260\2L\0\0\0\0\4\0\4\0\1\0\0\0\200\200\200\242\0\2\0\20\317\0\0\0\250\275\0\0\320\0\0\0\234\277\0\0\321\0\0\0|\301\0\0\322\0\0\0|\304\0\0\323\0\0\0\200\307\0\0\324\0\0\0|\312\0\0\325\0\0\0h\315\0\0\326\0\0\0\\\320\0\0\327\0\0\0\224\323\0\0\330\0\0\0\210\325\0\0\331\0\0\0h\327\0\0\332\0\0\0h\332\0\0\333\0\0\0l\335\0\0\334\0\0\0h\340\0\0\335\0\0\0T\343\0\0\336\0\0\0H\346\0\0\200\200\200\204 \0\0\0200\0\4\0\337\0\0\0", 8192, 25920) = 408 07:30:17 pread64(10, "", 8192, 26328) = 0 07:30:17 stat64("/home/ew/.maildir/.INBOX.vomiteer/dovecot.index.log", {st_mode=S_IFREG|0600, st_size=26328, ...}) = 0 07:30:17 fstat64(10, {st_mode=S_IFREG|0600, st_size=26328, ...}) = 0 07:30:17 time(NULL) = 1390289417 07:30:17 setsockopt(11, SOL_TCP, TCP_CORK, [1], 4) = 0 07:30:17 write(11, "* 32 EXISTS\r\n", 13) = 13 07:30:17 setsockopt(11, SOL_TCP, TCP_CORK, [0], 4) = 0 07:30:17 epoll_wait(9, <unfinished ...> (Nothing happened after this) #

This is probably easy but how would a set a secret static master password so that if I typed it in for any login it would be happy? I can't use the * separator method in this case because it screws up squirrelmail.

[Dovecot] Failure in doveconf
by Andrew Ray 21 Jan '14

21 Jan '14

I ran into a problem while configuring dovecot. Quickly reading the paragraph below, I saw "yes" as one of the options, and put that into the config, as below: # In case of password mismatches, log the attempted password. Valid values are # no, plain and sha1. sha1 can be useful for detecting brute force password # attempts vs. user simply trying the same password over and over again. # You can also truncate the value to n chars by appending ":n" (e.g. sha1:6). auth_verbose_passwords = yes The result from doveconf -n was: doveconf: Error: x�η doveconf: Fatal: Error in configuration file /etc/dovecot/dovecot.conf: 0pη (where the error message was always a changing, apparently random set of characters.) So I managed, by going back through the config file and commenting out options, to find this was the problem and then finally read what are the acceptable values. Any other place that I have tried to give a non acceptable value I get a reasonable error message with line number and problem. Well, now I fixed my original problem, but something needs to be adjusted in the error handling code.

[Dovecot] forwarded message is broken in 2.2.10 with pigeonhole-0.4.2
by Burckhard Schmidt 21 Jan '14

21 Jan '14

Hi, forwarding a message with sieve like redirect:copy "me(a)other.domain"; was working without any problem until dovecot-2.1.17, dovecots lmtp and dovecot-2.1-pigeonhole-0.3.5.

[Dovecot] Dovecot doesn't seem to report all subfolders to Thunderbird
by dovecot＠voidptr.de 21 Jan '14

21 Jan '14

Hi, I've recently migrated my emails from a Yahoo account to my own mailserver on a VPS. Ever since then, Thunderbird seems to have issues with the mailbox's directory structure: When I start Thunderbird, it immediately deletes the local copies of all 3rd-level folders (i.e. subfolders of a subfolder of a folder in the mailbox root). Since that didn't happen with the Yahoo account, I assume it's some kind of error or misconfiguration of Dovecot. Here's an example of the mailbox structure: voidptr.de '-> University '-> IEEE '-> Conference "University" and "IEEE" work without problems, but "Conference" gets deleted locally every time I start Thunderbird. When I collapse and re-expand "University" in the folder panel, all subfolders (including "Conference") reappear, but Thunderbird has to re-download the contents of "Conference", since it deleted the local copies earlier. It looks as if Dovecot only reported the topmost two folder levels when Thunderbird requests a folder list... Is there any way I can change that behavior?
