[Dovecot] Sieve vacation not working
by Phill Edwards 24 Feb '15

24 Feb '15

I've been trying all night to get vacation working in my .dovecot.sieve file. The way our email works is we have one account on dovecot which serves my mail and my wife's and we use procmail and sieve to put the emails in different folders depending on who it's for. I'm trying to set up a vacation reply on my wife's email address (aaaaaaaa@optus* below) so people can update to her new address. Here's my file with the email addresses masked: require ["fileinto", "vacation"]; if address :is "to" "xxxxxxxxxxxxxxx(a)ozemail.com.au" { fileinto "Phill_OzEmail_Folder"; stop; } elsif address :is "to" "yyyyyyyyyyyyyyyyy(a)optusnet.com.au" { fileinto "Phill_Optus_Folder"; stop; } elsif address :matches "to" "aaaaaaaa@optus*" { vacation "Please update my email address to bbbbbbbbb(a)exemail.com.au"; fileinto "Sarah_Optus_Folder"; stop; } else { keep; stop; } The problem I'm having is that no auto-replies are sent. I removed .dovecot.lda-dupes and that didn't help; so then I touched it and now it's a 0 byte file and that didn't help. There is no dovecot.sieve.err file and I can't see anything in /var/log/dovecot.log which gives any message about why this wouldn't work. The emails to aaaaaaa@optus* get filed into the right folder so I know the matching is working. I've also tried a reject recipe and that worked fine, so I know that it can send an email if it chooses to. So it's a complete black box mystery as to why it just won't send a reply. Regards, Phill

[Dovecot] Auth worker max line size
by Emmanuel Dreyfus 09 Sep '12

09 Sep '12

Hello I have been playing with some exotic authentication scheme with Dovecot and PAM. That involves sending really large base64 encoded data as the IMAP password, and I have hit a line limit in Dovecot, with AUTH_WORKER_MAX_LINE_LENGTH set to 1024. This limit is especially frustrating since other parts of the software use much larger limits: MAX_INBUF_SIZE 4096 MAX_IMAP_LINE 8192 AUTH_CLIENT_MAX_LINE_LENGTH 8192 I had to make the patch attached below to get my authentication working. I can live with this local patch, but given the much more liberal limits of MAX_INBUF_SIZE at 4096 makes we wonder if this 1024 limit on AUTH_WORKER_MAX_LINE_LENGTH could not be a bug. Or is there a security concern at using more than 1kB? Opinions?

[Dovecot] dovecot 1.2.3: TB fails to unsubscribe folder after deletion
by Max Dittrich 07 Mar '11

07 Mar '11

Hi, I'm running dovecot 1.2.3 with "imap_client_workarounds = tb-extra-mailbox-sep" and noticed that after deleting a folder (moving to Trash and emptying it on exit) that folder in Trash still keeps subscribed. I think the reason for that behavior is that the call for mailbox_list_set_subscribed() in imap/cmd-subscribe.c (line 84) is fed with the original mailbox name and not the stripped version in verify_name. Assigning verify_name to mailbox in the workaround-conditional fixes this issue for me. I'm not very familiar with C programming but while tracing cmd_subscribe_full() I stumbled upon another thing. In mail_namespace_find_mask() (lib-storage/mail-namespace.c at line 413) mailbox is reassigned with a local string (not t_strduped). I think this might be a problem when mailbox is dereferenced after returning from that function?! .max

[Dovecot] Can't connect to auth server
by Phill Edwards 13 Feb '11

13 Feb '11

I'm trying to phase out procmail and move to dovecot-sieve instead. It ain't proving easy. I'll describe my setup: - Centos 5.2 box with dovecot 1.1.4 and dovecot-sieve 1.1.6 from ATrpms. - A single user account is used to store all our email (the account is called maildb). - Getmail is being used to fetch the email from various ISP mailboxes. I want to deliver mail to different folders in maildb's Maildir/ depending on who the email is addressed to (the procmail recipes currently do that). - Getmail destination section looks like this: [destination] type = MDA_external path = /usr/libexec/dovecot/deliver arguments = ("-d", "maildb") allow_root_commands = true - When I run getmail I get this error in dovecot.log: deliver(maildb): May 04 22:15:26 Error: Can't connect to auth server at /var/run/dovecot/auth-master: No such file or directory It's true that I don't have a file called auth-master. I guess I should have but until I started this dovecot-sieve work it was never a problem. I have no idea what that file should look like. As I installed from binary RPMs I would have thought one would have come with the install. Can anyone help? Regards, Phill

[Dovecot] simple steps with sieve
by Gavin Hamill 02 Apr '10

02 Apr '10

Today is my first day with sieve, so be gentle :) I'm trying to set up a pretty webmail interface to our Dovecot 1.2.4 server using roundcube. The managesieve config + roundcube 'managesieve' plugin work fine, and I'm able to use roundcube's UI to generate .dovecot.sieve files. We use winbind + LDAP lookups to do some exotic mail rewriting... ultimately user.name(a)domain.com gets rewritten to 'ar-cloh@localhost', and in /home/AD/ar-cloh/.dovecot.sieve there is only this: require ["vacation"]; # rule:[gdh_test] if anyof (header :contains "Subject" "test") { vacation "test away"; } When I send an email to the user, I see this in the mail.log Oct 19 15:39:43 ar-smtp-1 dovecot: deliver(ar-cloh): sieve: msgid=<1255963176.14420.31.camel@gdh-work>: discarding vacation response for message implicitly delivered to <ar-cloh@ar-smtp-1> I don't understand; sending a vacation for implicitly-delivered messages sounds exactly like what I want - is there any way to say 'do this anyway' ? gdh

[Dovecot] Scalability plans: Abstract out filesystem and make it someone else's problem
by Timo Sirainen 12 Mar '10

12 Mar '10

This is something I figured out a few months ago, mainly because this one guy at work (hi, Stu) kept telling me my multi-master replication plan sucked and we should use some existing scalable database. (I guess it didn't go exactly like that, but that's the result anyway.) So, my current plan is based on a couple of observations: * Index files are really more like memory dumps. They're already in an optimal format for keeping them in memory, so they can be just mmap()ed and used. Doing some kind of translation to another format would just make it more complex and slower. * I can change all indexing and dbox code to not require any locks or overwriting files. I just need very few filesystem operations, primarily the ability to atomically append to a file. * Index and mail data is very different. Index data is accessed constantly and it must be very low latency or performance will be horrible. It practically should be in memory in local machine and there shouldn't normally be any network lookups when accessing it. * Mail data on the other hand is just written once and usually read maybe once or a couple of times. Caching mail data in memory probably doesn't help all that much. Latency isn't such a horrible issue as long as multiple mails can be fetched at once / in parallel, so there's only a single latency wait. So the high level plan is: 1. Change the index/cache/log file formats in a way that allows lockless writes. 2. Abstract out filesystem accessing in index and dbox code and implement a regular POSIX filesystem support. 3. Make lib-storage able to access mails in parallel and send multiple "get mail" requests in advance. (3.5. Implement async I/O filesystem backend.) 4. Implement a multi-master filesystem backend for index files. The idea would be that all servers accessing the same mailbox must be talking to each others via network and every time something is changed, push the change to other servers. This is actually very similar to my previous multi-master plan. One of the servers accessing the mailbox would still act as a master and handle conflict resolution and writing indexes to disk more or less often. 5. Implement filesystem backend for dbox and permanent index storage using some scalable distributed database, such as maybe Cassandra. This is the part I've thought the least about, but it's also the part I hope to (mostly) outsource to someone else. I'm not going to write a distributed database from scratch.. This actually should solve several issues: * Scalability, of course. It'll be as scalable as the distributed database being used to store mails. * NFS reliability! Even if you don't care about any of these alternative databases, this still solves NFS caching problems. You'd keep using the regular POSIX FS API (or async FS api) but with the in-memory index "cache", so only a single server is writing to mailbox indexes at the same time. * Shared mailboxes. The filesystem API is abstracted, so it should be possible to easily add another layer to handle accessing other users' mails from both local and remote servers. This should finally make it possible to easily support shared mailboxes with system users.

[Dovecot] Capability COMPRESS implemented?
by Ed W 15 Feb '10

15 Feb '10

Hi, I just read that http://tools.ietf.org/html/rfc4978 ..is being implemented in Thunderbird 3. This is great news! It's been a long time since we last discussed this and I don't think it's currently implemented in Dovecot, but since Cyrus just added it, any chance of getting support in Dovecot please? (Fastmail seems to be supporting this effort) On a similar note we had a previous thread about supporting TLS deflate - any chance you could investigate this again and add support on the Dovecot side so at least it would be feasible to submit a bug fix on the Thunderbird side? (It looked like a one liner change back when we last discussed it?) Thanks Ed W (Obviously for those looking for an external high performance compressor you can use our compressing email proxy from http://www.mailasail.com ...)

[Dovecot] dovecot-auth stops responding
by Jonathan Siegle 05 Feb '10

05 Feb '10

Running dovecot 1.2.4(imap only) on AIX out of inetd. I accept passwords(PAM for auth) and kerberos tickets. Occasionally we see dovecot-auth stop responding. I just kill it off and another process is spawned which works fine. It doesn't look like it is hitting any ulimits(11MB for memory). I issued a kill -11 and ran it through the debugger. Here is what it says: dbx dovecot-auth core Type 'help' for help. [using memory image in core] reading symbolic information ... Segmentation fault in __fd_poll at 0x900000000117634 ($t1) 0x900000000117634 (__fd_poll+0x98) e8410028 ld r2,0x28(r1) (dbx) where __fd_poll(??, ??, ??) at 0x900000000117634 ioloop-poll.poll(__listptr = 0x00000001104dd330, __nfds = 145, __timeout = 1051), line 121 in "poll.h" io_loop_handler_run(ioloop = 0x000000011001bfb0), line 157 in "ioloop- poll.c" io_loop_run(ioloop = 0x000000011001bfb0), line 335 in "ioloop.c" main(argc = 1, argv = 0x0ffffffffffffad8), line 347 in "main.c" Here are my ulimits: ulimit -a time(seconds) unlimited file(blocks) 2097151 data(kbytes) 1048576 stack(kbytes) 65536 memory(kbytes) 65536 coredump(blocks) 2097151 nofiles(descriptors) 32768 Any help would be appreciated.

[Dovecot] Fatal: chdir( ) failed: Permission denied
by Vallo Kallaste 05 Feb '10

05 Feb '10

Hi Dovecot fails to chdir() into users home directory giving the following error: Oct 9 16:43:49 jura dovecot: dovecot: Fatal: chdir(/a/home/mina) failed: Permission denied (euid=1118 0(mina) egid=11332(devel) missing +x perm: /a/home) Oct 9 16:43:49 jura dovecot: dovecot: child 14441 (imap) returned error 89 (Fatal failure) The reason seems to be that user primary group is "devel" and directory /a/home has ACL which gives execute permission only to the users in "domain users" group. Now the catch is that the user _is_ member of "domain users" group and is happily accessing his home directory over CIFS(Samba) for long time. Also, the user has no problem entering his home directory when using shell access. It just seems like the user lost membership of a bunch of supplementary groups. The group membership info is coming from M$ PDC via winbind and NSS. We have few users and can change the users primary group and/or relax the /a/home directory ACL, but overall this is not right. Shall I shut up or can we hope for a fix or at least explanation? Thanks jura:/a # ls -la drwxrws--T+ 3 root domain admins 18 Oct 8 15:10 home jura:/a # getfacl home/ # file: home # owner: root # group: domain\040admins user::rwx group::rwx group:domain\040users:--x mask::rwx other::--- -- Vallo

[Dovecot] Two different issues with dovecot 1.1.13
by Stuart Rowan 20 Jan '10

20 Jan '10

Hi Timo, I'm using Debian backports.org dovecot-imapd, 1:1.1.13-2~bpo50+1. I've got two different issues, a reoccurring, seemingly harmless one about "Corrupted index cache file" (boring.txt) and one that went bonkers over the least few days (bt.txt) causing much spamming of the logs. I've made bt.txt stop happening by just rm'ing dovecot.index* : find Maildir/ -type f -name 'dovecot.index*' -print0 | xargs -0r rm ... which I realise may not be the most helpful thing to have done from your point of view. Anyway I just wanted to let you know about both of these. If one or both are already known about or already fixed by a later version of Dovecot, great and sorry for the noise! If not, and you want any more information etc., let me know. Many thanks, Stu. dovecot: 2009-07-28 10:23:16 Error: IMAP(strr): Corrupted index cache file /home/local/strr/Maildir/dovecot.index.cache: record continues outside its allocated size dovecot: 2009-07-28 10:23:56 Error: IMAP(strr): Corrupted index cache file /home/local/strr/Maildir/dovecot.index.cache: record continues outside its allocated size dovecot: 2009-07-28 08:05:54 Panic: IMAP(strr): file index-mail-headers.c: line 77 (index_mail_parse_header_finish): assertion failed: ((match[match_idx] & HEADER_MAT CH_FLAG_FOUND) == 0) dovecot: 2009-07-28 08:05:54 Error: IMAP(strr): Raw backtrace: imap [0x48dbf2] -> imap [0x48dc73] -> imap [0x48d346] -> imap(index_mail_parse_header+0x617) [0x4545f7] -> imap [0x483284] -> imap [0x483478] -> imap(i_stream_read+0x2c) [0x491d7c] -> imap(i_stream_read_data+0x46) [0x491f16] -> imap(message_get_body_size+0x108) [0x4885 a8] -> imap [0x4226c3] -> imap(imap_fetch+0x162) [0x420852] -> imap(cmd_fetch+0x23c) [0x41a27c] -> imap [0x41e46c] -> imap [0x41e51d] -> imap [0x41eb25] -> imap(clien t_input+0x63) [0x41efd3] -> imap(io_loop_handler_run+0xcb) [0x49515b] -> imap(io_loop_run+0x18) [0x4945c8] -> imap(main+0x3da) [0x426bea] -> /lib/libc.so.6(__libc_sta rt_main+0xe6) [0x7f0e851941a6] -> imap [0x418859] dovecot: 2009-07-28 08:05:54 Error: child 20007 (imap) killed with signal 6 (core dumps disabled) dovecot: 2009-07-28 08:05:56 Panic: IMAP(strr): file index-mail-headers.c: line 77 (index_mail_parse_header_finish): assertion failed: ((match[match_idx] & HEADER_MAT CH_FLAG_FOUND) == 0) dovecot: 2009-07-28 08:05:56 Error: IMAP(strr): Raw backtrace: imap [0x48dbf2] -> imap [0x48dc73] -> imap [0x48d346] -> imap(index_mail_parse_header+0x617) [0x4545f7] -> imap [0x483284] -> imap [0x483478] -> imap(i_stream_read+0x2c) [0x491d7c] -> imap(i_stream_read_data+0x46) [0x491f16] -> imap(message_get_body_size+0x108) [0x4885 a8] -> imap [0x4226c3] -> imap(imap_fetch+0x162) [0x420852] -> imap(cmd_fetch+0x23c) [0x41a27c] -> imap [0x41e46c] -> imap [0x41e51d] -> imap [0x41eb25] -> imap(clien t_input+0x63) [0x41efd3] -> imap(io_loop_handler_run+0xcb) [0x49515b] -> imap(io_loop_run+0x18) [0x4945c8] -> imap(main+0x3da) [0x426bea] -> /lib/libc.so.6(__libc_sta rt_main+0xe6) [0x7f2edf08b1a6] -> imap [0x418859] dovecot: 2009-07-28 08:05:56 Error: child 20984 (imap) killed with signal 6 (core dumps disabled)

[Dovecot] expire plugin + --exec-mail in 1.2.6 version
by Nikita Koshikov 25 Nov '09

25 Nov '09

Hello list, After upgrade to dovecot version 1.2.6 I have noticed some quota malfunctions(users become often overquota). Looking at logs closely I have found that quota value resets to general dovecot-config( quota = maildir:Mailbox quota quota_rule = *:storage=500M quota_rule2 = Trash:storage=10%% ), after dovecot --exec-mail ext /usr/libexec/dovecot/expire-tool.sh command. The problem that some users have their own quotas stored in ldap. For example, user sr(a)domain.com have maildirsize before running expire-tool(1G value from ldap): # head -2 /data/mail/domain.com/sr/data/maildirsize 10485760000S 836423205 8285 Then I run

[Dovecot] v2.0 lmtp logging
by Pascal Volk 05 Nov '09

05 Nov '09

Hi, I am not yet completely happy with the logging behavior of the lmtp. It logs informative messages like 'lmtp: Info: Connection closed' or 'lmtp: Info: Disconnected for inactivity'. Hm, which server was connected to the lmtp? Who was disconnected for inactivity? I think it would be useful if the lmtp would also log new connections. For example: a) TCP connections: lmtp: Info: Connection: rip=10.1.2.3, lip=10.1.2.5, cid=1255555555.12345 b) Socket connections: lmtp: Info: Connection: via socket, cid=1255555777.10452 rip: There may be multiple SMTP servers in front the IMAP server(s) lip: The lmpt may listen to more than one address cid: The 'connection ID', consists of the current unix time and the pid of the lmtp process. (Or some other values in some other format) The cid should be used in the 'saved' messages. So the delivering MTA would see something like '250 2.0.0 OK: 1255555555.12345 Saved', instead of a message like '250 2.0.0 <jdoe(a)example.com> Saved'. The lmtp should also write the cid to the log. For example: 'lmtp(jdoe): Info: msgid=123, cid=1255555555.12345: saved mail to INBOX' (or discarded because of a matching sieve rule). With this connection ID it would be possible to trace the route which the e-mail has taken. Regards, Pascal -- The trapper recommends today: c01dcafe.0929623(a)localdomain.org

[Dovecot] meaning of parameter imap_idle_notify_interval??
by Ingo Thierack 05 Nov '09

05 Nov '09

Hello, is my understanding of the parameter "imap_idle_notify_interval" right, if i say, it's the time between two point where dovecot tells the client he is here, and sould have nothing directly todo with the notification of new mails arrived. I played with the values around. And the courios is, in thunderbird the folloing. set to 30 seconds. Thunderbird pop up around 25 seconds after the message is deliverd to the inbox. set to 60 seconds. Thunderbird pup up around 50 seconds after the message is deliverd to the inbox. I switch over from archiveopteryx, where no such delay was. Regards, Ingo

by Juergen Obermann 03 Nov '09

03 Nov '09

Hallo. In our dovecot 1.2.6 server running under Solaris 9 I would like to set up a second quota root because the mail folders are in the users home directories and the inboxes of all users are in /var/mail. As soon as I add quota2 = fs:INBOX:noenforcing:mount=/var/mail the imap client crashes repeatedly as soon as the user tries to open a mail folder. Thanks for any help.

[Dovecot] Author wanted for Dovecot article in Linux Magazine (Germany)
by Markus Feilner 31 Oct '09

31 Oct '09

Hi list, I am an editor at the German Linux Magazine and I am searching for an author or input on Dovecot, its advantages and especially the recent features. I had organized some authors, but unfortunately they don't have time right now. :-) Nevertheless I heard many positive comments on Dovecot. I can write or help writing the article, but I would love to have some input from an experienced dovecot admin - perhaps with some stunning, unusual setup that might interest our readers (most of them are skilled admins and programmers...) Something that can't be easily done with other mail servers would be great, something spectacular that is suitable to convince an mail admin why he should migrate to Dovecot. It won't be long, just about 2-3 pages (a maximum of 15000 characters) including screen shots and/or listings, code, > 10 Links and an author's biography with photo. Anybody interested? That would be great, feel free to send me a mail to: mfeilner(a)linuxnewmedia.de Unfortunately, we don't have much time, there's only two weeks left, but I will help and do a lot of work for the article. And don't worry about language! :-) Thanks a lot! -- Best Regards - Mit freundlichen Gruessen Markus Feilner ------------------------- Feilner IT Linux & GIS Linux Solutions, Training, Seminare und Workshops - auch Inhouse Koetztingerstr 6c 93057 Regensburg Telefon: +49 941 8 10 79 89 Mobil: +49 170 3 02 70 92 WWW: www.feilner-it.net mail: mfeilner(a)feilner-it.net Bei Xing: http://www.xing.com/profile/Markus_Feilner -------------------------------------- My OpenVPN book - OPENVPN : Building and Integrating Virtual Private Networks http://www.packtpub.com/openvpn/book My new book - Out now: SCALIX Linux Administrator's Guide http://www.packtpub.com/scalix/book

[Dovecot] Dovecot in-house benchmarking
by Joseba Torre 30 Oct '09

30 Oct '09

Hi, Before some major changes in our infrastructure, I was interested in the performance impact of moving indexes to our NAS (Emc Celerra v5.5). So I downloaded both dovecot-1.1.19 and dovecot-1.2.6, compiled them and wrote 2 confs for each of them, one with local indexes and another with indexes in the NAS. Then I created 19 pam users, and tested system performance this way: - uninstall current installed version - install a new version - start dovecot - for each user run: imaptest user=user pass=pass host=localhost port=143 mbox=${MBOX} seed=123 secs=300 | tail -1 > file - stop dovecot I'm not sure if these tests are real, but our results are: * In our conf, 1.1.19 and 1.2.6 performance are roughly the same * Moving the indexes to our NAS makes the system 3 times slower As we currently only have 1 system accessing mails or indexes, I tried later with nfs_* = no, and mmap_disable = no. This makes performance 10% better in any situation. Our testing setup (very close to the real one) - Dell PowerEdge 2850, 2 P4 Xeon 3GHz, 3GB RAM - RHEL 4.7 (not sure about this, the last RHEL4) 32 bits - mailboxes are always in a nfs filesystem - for testing mbox file I've used dovecot-cvs.mbox I've attached a couple of graphs to show this results (I've a lot of them, but result are pretty close from one to another). Also, dovecot -n output for 1.2.6 with indexes in the NAS. Only needed changes have been applied from one conf to another. If you feel that the benchmark can be more "real" with some changes, just tell me. Also, if you are interested in the rest of graphs or date, tell me. Next week I'll be quite busy, but as soon as possible I'll test with an iSCSI disk for indexes. Aaaaaaaaaaagur. -- Joseba Torre. Vicegerencia de TICs, área de Explotación

[Dovecot] How to see if sieve is active ?
by Koenraad Lelong 30 Oct '09

30 Oct '09

Hi, I think I activated sieve, but it's doing nothing. I know manage-sieve works so I made some rules. But they do nothing. I ran sieve-test, which seems to work, but does not move the mail I test. Is this how it works ? I thought the -e parameter just "tested" the rules and did nothing and my command was supposed to do the "real thing". I read there should be a log. I don't find this, how should I enable this ? I just found that lda can have a separate log. I'll enable this and see. I read the wiki-page different times, but I don't see what I'm doing wrong. I attached some files. Sieve-test.txt is the command and output from sieve-test. Phpscript.sieve is the file .dovecot.sieve points to, and dovecot-config is my dovecot config ;-). Thanks for any pointers.

[Dovecot] dovecot-shared and shared "\Seen" flags
by Dave 29 Oct '09

29 Oct '09

(Running Dovecot 1.1.0) Is it possible to either - (a) Still have shared "\Seen" flags even while using the dovecot-shared file or (b) Indicate to Dovecot in some way other than the dovecot-shared file which permissions to use for any messages created? The problem is, in my shared folder (using symlinks) scenario I am using, I have to use the dovecot-shared file to make sure new messages get written with the correct user and group permissions so that everyone appropriate can access them, but I still would like the functionality of the shared "\Seen" flags in these shared/symlinked folders (which having dovecot-shared seems to knock out). Is it possible to do both somehow? Dave

Option (a) sounds like the cleanest solution, but a bit of testing showed that Postfix doesn't wait on deliver before replying to DATA so this seems to always result in a bounce. I've perused the postfix documentation but so far no luck; if anyone reading this has any insight on how we might configure postfix to behave this way, could you please let me know (maybe offlist would be best, as this may be considered somewhat off-topic). We are using something similar to option (b) currently, but it's not really an elegant approach and we would really like to move away from it. Option (a) sounds great, if we can somehow get it to work. TIA, Marty

[Dovecot] Question about Windows Mail for Vista IMAP client
by Stewart Dean 29 Oct '09

29 Oct '09

When TBird logs on, it does it quietly, that is it opens one or two logins. When you start working it'll open a few more. Quiet, no thrashing around When WM4Vista opens, it appears to login and disconnect (immediately) once for every folder a person has. 20 folders, 20 logins and disconnect, ripple fire. Anybody have an idea why WM4V is so busy and TB is quiet doing the same thing? I fell over this doing testing on V1.2.6 but find it's also the case back on my production V1.1.15 -- ==== Once upon a time, the Internet was a friendly, neighbors-helping-neighbors small town, and no one locked their doors. Now it's like an apartment in Bed-Stuy: you need three heavy duty pick-proof locks, one of those braces that goes from the lock to the floor, and bars on the windows.... ==== Stewart Dean, Unix System Admin, Bard College, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

[Dovecot] Wish-list: X-Delivered-To headers generated by dovecot-deliver
by Andrzej Adam Filip 29 Oct '09

Would it be sensible/"cost effective" to make dovecot-deliver generated X-Delivered-To header(s) based on command line parameter(s)? [after striping such existing headers, before consulting sieve] I need it to: a) *clearly* mark POP/IMAP account fetched by fetchmail [with fetchmail using directly dovecot-deliver in --mda option] b) cleanly implement "shared mailboxes" with MTA such as sendmail that can be easily forced to generate "one header per one recipient" [AFAIK] -- [pl>en: Andrew] Andrzej Adam Filip : anfi(a)onet.eu Order and simplification are the first steps toward mastery of a subject -- the actual enemy is the unknown. -- Thomas Mann

[Dovecot] Multiple LDAP Userdb lookups
by David 29 Oct '09

29 Oct '09

Hello one & all, I understand it is possible to do multiple lookups for userdb info of different types, for instance a local "real" account & virtual MySql lookups. Is it possible to do two separate ldap lookups to differnt parts of the same AD domain? I have a config file to do my authentication lookup against the domain. Then I have a 2nd config file for the userdb lookups which uses ldap to query our AD for their userdb info. I need to query a 2nd part of the AD for another group of users & unfortunately putting all users into one container isn't possible. So, if I add another ldap stanza to dovecot.conf will I break anything? Cheers, David. This email is confidential and is intended solely for the use of the parties to whom it is addressed.

[Dovecot] Thunderbird and Trash folder
by Stefan Onken 29 Oct '09

29 Oct '09

Hello, I have my problems with the Trash folder in thunderbird. Most of the times (it did work, but only for a short period) Thunderbird is not considering the "Trash" folder (or in my case the "Papierkorb") as the trash folder. The symbol disappears and I am not able to delete folders. Deleted emails are disappearing at all. The usual Google solutions like maildir vs. mbox doesn't help a lot, I am using maildir and the directory structure looks fine. I noticed that I have two trash folders, one with "INBOX.", one without. That may be a problem with Squirrelmail, because I am using both Thunderbird and Squirrelmail. Any idea to solve this issue with Thunderbird ? Thank you, Stonki Dovecot -a: http://www.pastebin.org/49066 Directory structure: http://www.pastebin.org/49067

[Dovecot] Multiple SSL certs question
by Jean-Baptiste Vignaud 29 Oct '09

29 Oct '09

Hello; I was reading the message "how to config dovecot for multiple domains, multiple SSL certs, and conditional IP access -- with passwd-file passdb?", and i was wondering if Dovecot could support the SNI extention of TLS ? SNI is Server Name Indication where during the TLS negotiation, the client set the name of the server it tries to reach I dont know if any imap/pop client support this yet, but this would be a great feature for one IP/multiple virtual domains. Each SNI client would have the correct certificate and not the "main/generic' one. It seems that mutt has a patch for that http://www.mail-archive.com/mutt-dev@mutt.org/msg05251.html

[Dovecot] Hundreds of auth-worker sockets in /etc/dovecot
by Eggert Ehmke 28 Oct '09

28 Oct '09

I run dovecot 1.2.6, before last update I had 1.2.2. on Debian Lenny. I noticed that my config directory /etc/dovecot is filled up with hundreds of old auth-worker.12345 sockets. I guess they should have been cleaned up, is there a misconfiguration? When I remember right, this did not happen with dovecot 1.1.

[Dovecot] listing available subscriptions - shared mailboxes
by Hendrik Pahl 28 Oct '09

28 Oct '09

hi everybody, got a strange issue with 1.2.4 on SLES11. When listing the user's available subscriptions with any client, every shared mailbox that can be subscribed is listed twice, once with it's correct name, 'folder' for example. the second appereance is without the last letter of the name, 'folde' for example. strange behaviour, since this happens with any client. i hope somebody know what is wrong here. thanks in advance, hendrik -- LWsystems GmbH & Co.

[Dovecot] Sieve vacation with russian subject
by Nikita Koshikov 28 Oct '09

28 Oct '09

Hello list, I have noticed that sieve vacation action breaks some non-english letters in the subject. I tested with russian language, if subject contains letters from specific diapason russian alphabet, the message received with unreadable subject, but text in the body with the same letters looks ok. Here is example of full subject header, it contains russian alphabet: Subject: абвгде�?жзийклмноп�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�? Maybe this headers will be usefull: MIME-Version: 1.0 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 8bit .dovecot.sieve file looks correct, here is it: require ["vacation"]; # rule:[test] if anyof (true) { vacation :days 1 :addresses ["user(a)domain.com"] :subject "абвгдеёжзийклмнопрстуфхцчшщъыьэюя" text: Тестовое русское сообщение(Test russian message). ; } I'm running dovecot-1.1.16 with dovecot-sieve-1.1.6 and managesieve-0.10.6. Please tell, is it possible to fix this ?

[Dovecot] antispam-plugin 1.2 and trailing carriage-returns
by Karsten Bräckelmann 28 Oct '09

28 Oct '09

Guys, Dovecot 1.0.15 [1], just built the latest antispam-plugin 1.2 (tarball) for testing, mailtrain backend for SA integration. Both built from custom spec files. The mail that is being trained is different than its respective source in the mbox file. The trained one shows added, trailing carriage-return chars for all headers, which are not in the headers in the mbox file. This breaks sa-learn -- both these variations are different, and SA would learn *both* when run against each one separately. How comes? Any insight? How could I fix this, other than wrapping the sa-learn inside another shell script and have sed strip off the noise? This becomes more of an issue, once I switch from sa-learn to the lightning-fast spamc training variant. TIA guenther [1] Yes, I know, sorry. Don't want to change everything at the same time, and the target system I'm experimenting for runs that version, too. -- char *t="\10pse\0r\0dtu\0.@ghno\x4e\xc8\x79\xf4\xab\x51\x8a\x10\xf4\xf4\xc4"; main(){ char h,m=h=*t++,*x=t+2*h,c,i,l=*x,s=0; for (i=0;i<l;i++){ i%8? c<<=1: (c=*++x); c&128 && (s+=h); if (!(h>>=1)||!t[s+h]){ putchar(t[s]);h=m;s=0; }}}

[Dovecot] Dovecot, Shared Mailboxes (via symlink), and ACLs
by Dave 27 Oct '09

27 Oct '09

Hello! I just joined the list and will be happy to help where I can in my limited experience, but also come to the table with a question. I think there's something I'm missing regarding shared mailboxes and ACLs, so I will describe my situation and see if I am understanding correctly (running Dovecot 1.1.10). I have read over the Dovecot Wiki many times and have scoured many forums but still can't seem to find a solution. I have an IMAP mailbox that is working fine (user imapuser), so the maildir and related structure is in: /home/imapuser/Maildir I have another IMAP mailbox for another imap user, newuser1, also working fine, with maildir and related structure in: /home/newuser1/Maildir I have created a symlink under newuser1's Maildir to imapuser's Maildir so as to give newuser1 access to the things in imapusers's inbox. I have also symlinked inside the newuser1 Maildir to a folder under imapusers's inbox, let's call it "MailingList", basically settiing up something like: /home/newuser1/Maildir: cur/ .imapuserinbox -> /home/imapuser/Maildir .imapusermailinglist -> /home/imapuser/Maildir/MailingList new/ tmp/ (... and various other Dovecot-related files, nothing ACL related.) Now, I have gotten the shared boxes to work IF I changed the permissions to be rwx for user and group on /home/imapuser/Maildir/*, but this makes procmail (and .procmailrc) unhappy and it starts sending things to mbox files (old system) instead of sending them on to the Maildir. So that doesn't seem to work. Which led me to ACLs. Now, I've tried (after enabling the two appropriate lines in dovecot.conf and restarting dovecot, etc) both per-directory ACL files and global ACLs, and while I can get some things to *change* as viewed by my mail client, I can't seem to create consistent behavior. I know that's fairly vague, but it's like I'll change something in the global ACL and folders are affected that I wouldn't anticipate, based on what I'm understanding of ACLs. So, in the example above, if I enable global ACLs, what names do I use to refer to those shared boxes I'm trying to access? Do I use the link name I made, .imapuserinbox or .imapusermailinglist (without leading periods), like /etc/dovecot/acls/imapuserinbox, or is it based off of the original dir name? Like do I need something like /etc/dovecot/acls/MailingList ? What about the "inbox" I'm sharing in /home/imapuser/Maildir, how do I reference that? Is there a way to do it without affecting or changing permissions of other IMAP users and inboxes on the same system? One thing I am receiving consistently in the error logs is: mail dovecot: IMAP(newuser1): stat(/home/newuser1/Maildir/.imapuserinbox/tmp) failed: Permission denied (euid=152(newuser1) egid=100(usergroup) UNIX perms seem ok, ACL problem?) So it seems if I get the ACL stuff right, I will be in business. Any ideas?? Thanks for any help anyone can give!! Dave

[Dovecot] 1.1 Quota Question
by Marty Anstey 27 Oct '09

27 Oct '09

Hi, I'm not sure if this question has been asked before but some googling hasn't turned up anything really relevant. We are currently running Dovecot 1.1.16 & Postfix; maildir++. When a message arrives for a mailbox which is over quota, it is bounced. Obviously, this isn't very desirable; the primary downside to this is that when junk mail hits a full mailbox it's bounced to that recipient of the message. On a busy mail system, that could potentially get us blacklisted pretty quickly. Ideally we would like to reject the messages inline. Is there an easy way to set this up? Thanks, Marty

[Dovecot] Error: userdb lookup
by kfx 27 Oct '09

27 Oct '09

Hi list, I am trying to get rid of the "Error: file_dotlock_create(~/.dovecot.lda-dupes) failed: No such file or directory" by adding home directories to my virtual users (ldap).

[Dovecot] dovecot.log file permissions and ownership
by Jerry 27 Oct '09

27 Oct '09

Using FreeBSD-7.2 and Dovecot v1.2.4 what user does dovecot use to write to its log file? I have the logfile located in the /var/log directory. I have Postfix configured to use 'virtual' users and use dovecot for delivery. While dove can write to the file when accessed for POP services, when accessed via Postfix, I get this error message: Oct 25 07:02:15 scorpio postfix/pipe[56956]: B01BD2287E: to=<user(a)domain.com>, relay=dovecot, delay=220, delays=220/0.01/0/0.04, dsn=4.3.0, status=deferred (temporary failure. Command output: Can't open log file /var/log/dovecot.log: Permission denied ) I have used the following ownership types for the file: 1) root:wheel 2) dovecot:dovecot 3) root:dovecot 4) dovecot:wheel The only thing that works all the time is to give the file full r/w (0666) permission. That seems extreme. -- Jerry gesbbb(a)yahoo.com |::::======= |::::======= |=========== |=========== | A nuclear war can ruin your whole day.

[Dovecot] SetUID check problem
by Thomas Berezansky 27 Oct '09

27 Oct '09

Running dovecot 1.2.4 on FreeBSD using Postfix. Everything works fine normally, but deliver is executable by world. This is not normally a problem, as I don't run deliver SetUID root. But for whatever reason, when deliver is called by something that IS SetUID root I get the following error: /usr/local/libexec/dovecot/deliver must not be both world-executable and setuid-root. This allows root exploits. See http://wiki.dovecot.org/LDA#multipleuids Deliver's permissions look like this: -r-xr-xr-x While the program calling deliver has permissions like this: -r-s--x--- If it isn't possible for deliver to differentiate between being called by setuid root programs and being setuid root itself I don't think it should be doing that particular security check. Alternatively, there should be an option to turn that particular check off, but what little I saw of the source code and found searching the documentation told me that there doesn't seem to be such an option already. I also couldn't find any mention that this is fixed by 1.2.5 or 1.2.6. Thomas Berezansky Merrimack Valley Library Consortium

[Dovecot] Test environment question
by Stewart Dean 27 Oct '09

27 Oct '09

I want to test out my first V1.2 Dovecot (upgraded from V1.1) instance. What I have in mind to do is to run it on another machine that has the Inbox dir and homedirs NFS import mounted from the production mailserver. I then have 5 people test it in this test environment.... A) Then I can deal with the index filesystem in one of two ways: 1) Make it local OR 2) NFS import it from the production DC server Comments as to which is best? I have used #1 before...which caused some temporary unhappiness with the switchover and switchback....during which time the index is badly wrong and DC auto-rebuilds it... B) Is there anything else I should do/not do? C) Any ugliness that will surface in this testing lashup but isn't important? -- ==== Stewart Dean, Unix System Admin, Henderson Computer Resources Center of Bard College, Annandale-on-Hudson, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

[Dovecot] Multiple identities
by Koenraad Lelong 27 Oct '09

27 Oct '09

Hi, I recently moved from courier-imap to dovecot, to be able to work with managesieve. I use version 1.2.5, on suse 10.3. I used the script to migrate the courier maildir to dovecot format. It seems to work fine except for one problem : I use a number of aliasses and with Thunderbird I can select which alias (e-mail-address) to use as my identity when sending a mail. I sniffed with wireshark, and with my standard identity, I see the message appended to "Sent", like I expect. If I use an alias, I see a folder being created : "INBOX.Sent", and then the message is appended there. Why the difference ? I'm trying to debug this but dovecot does not help much. I tried rawlog but there is no output (that I see) from it, no log-files in my maildir. Any hints how to proceed ? Output op dovecot -n : # 1.2.5: /etc/dovecot/dovecot.conf # OS: Linux 2.6.22.19-0.4-default x86_64 openSUSE 10.3 (X86-64) base_dir: /var/run/dovecot/ log_path: /var/log/dovecot log_timestamp: %Y-%m-%d %H:%M:%S listen: *:143 ssl_listen: *:993 ssl_ca_file: /etc/postfix/certificate/cacert.org.pem ssl_cert_file: /etc/postfix/certificate/mailbox.pem ssl_key_file: /etc/postfix/certificate/mailboxkey.pem disable_plaintext_auth: no verbose_ssl: yes login_dir: /var/run/dovecot//login login_executable: /usr/lib/dovecot/imap-login first_valid_uid: 499 last_valid_uid: 499 mail_location: maildir:/var/vmail/%d/%u mail_debug: yes mail_executable: /usr/lib/dovecot/rawlog /usr/lib/dovecot/imap lda: postmaster_address: postmaster(a)mydomain.com sendmail_path: /usr/lib/sendmail auth_socket_path: /var/run/dovecot/auth-master mail_plugins: cmusieve auth default: mechanisms: plain login user: nobody verbose: yes debug: yes passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: sql args: /etc/dovecot/dovecot-sql.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 432 user: vmail group: vmail Kind regards, Koenraad Lelong.

[Dovecot] Multiple postfix + single dovecot - optimal configuration
by Tomek 26 Oct '09

26 Oct '09

Hello, I want to setup dovecot with two postfix servers on three machines: - dovecot - with huge amount of disk space - where all user emails will be kept, - postfix1 - with greylisting, amavisd-new (spamassassin, clamav, etc), with mysql backend, - postfix2 - same as postfix1. MX priority will be set to the same value for both postfix machines. For now I don't know how to "glue" these severs: - if I should install dovecot on both postfix and use third servers as a NFS share? - or maybe it is possible to communicate with dovecot on third server via LMTP? - or should I run third postfix daemon (without antyspam etc - simple configuration) on the same machine as dovecot only for delivering local mails? I will be grateful for any advice, howto or good practices example. -- Regards, Thomas.

[Dovecot] protocol configure confusion
by Stewart Dean 26 Oct '09

26 Oct '09

The docs say: > > *protocol*s = imap *imaps* > *Protocol*s we want to be serving: imap *imaps* pop3 pop3s If you > only want to use dovecot-auth, you can set this to "none". > and..... > > If you want to specify ports for each service, you will need to > configure these settings inside the *protocol* imap/pop3 { ... } > section, so you can specify different ports for IMAP/POP3. For example: > > # *protocol* imap { > # listen = *:10143 > # ssl_listen = *:10943 > # .. > # } > So if I want to run both imap and imaps AND configure the port, do I do: # *protocol* imap { # listen = *:143 # ssl_listen = *:10943 # } OR # *protocol* imap { # listen = *:143 # } # *protocol* imaps { # listen = *:993 # }

[Dovecot] Rotating the dovecot log file
by Jerry 24 Oct '09

24 Oct '09

Using FreeBSD-7.2, I am attempting to configure the system newsyslog utility to rotate the dovecot.log file. I would prefer to use the system utility rather than the one described on the dovecot wiki for rotating the file. Unfortunately, it is not working. This is the error message that is spawned: newsyslog: illegal signal number in config file: /var/log/dovecot.log root:wheel 0666 1 * $M1D0 CJ /var/run/dovecot/master.pid USR1 Does anyone have an idea how to get this to work?

[Dovecot] v2.0.alpha2 released
by Timo Sirainen 23 Oct '09

23 Oct '09

http://dovecot.org/releases/2.0/alpha/dovecot-2.0.alpha2.tar.gz http://dovecot.org/releases/2.0/alpha/dovecot-2.0.alpha2.tar.gz.sig Changes since alpha1: - All debug messages are now logged to debug log (debug_log_path setting, defaults to info_log_path). Patch by Pascal Volk. - Added support for SORT=DISPLAY IMAP extension. - Added doveadm who command for listing currently logged in users. - ssl_ciphers_list: Disable anonymous and export ciphers by default. - mail_chroot can now contain %variables (e.g. /home/%u) - fixed a bad maildir crashing bug - ssl-params is now run with +15 priority when generating the ssl parameters - Redesigned how login processes log in and create imap/pop3 processes. This fixes several settings and some other problems, plus it's now also possible for a single imap/pop3 process to handle multiple connections. If you want to try this, modify master.conf: service imap { # comment out: #service_count = 1 # This should be at least the number of CPUs, maybe more (2-3x?) process_min_avail = 4 # Limit the number of clients a single process can handle. # Disk IO is blocking, so some commands can take a while. client_limit = 5 } It currently doesn't even try to group same user's connections to same process, they'll just go randomly to whichever process manages to accept it first. Some day perhaps there should be a new service in the middle that keeps track of existing connections and forwards new ones to right mail processes. v2.0.beta1 TODO list: - master.conf has to be somehow put into defaults, so doveconf -n doesn't show its contents. an example master.conf would be minimal and show only those settings that admin might want to change (and those would show up in doveconf -n) - verbose_proctitle=yes is now quite useless because of the imap/pop3 process creation change. Probably enable linux-proctitle-hack and start changing the proctitle much more often. For example it could contain the command that's currently being run by user. And login processes could contain how many client connections they currently have. And other processes too something similar.. - change plugin hook design to allow multiple users in same process to run different plugins See alpha1 release announcement for more about these TODO: - v1.x config backwards compatibility - dsync is buggy - config process is slow - tcp-wrappers support

Hi, one Fedora user complains about not some troubles after update to dovecot 1.2. He suspects wrong capability information given by dovecot 1.2 In dovecot.conf he uses imap_capability= option. While response to 'A CAPABILITY' respects imap_capability value, the capability info in hello message does not. for imap_capability=IMAP4 IMAP4rev1 ACL NAMESPACE CHILDREN SORT QUOTA THREAD=ORDEREDSUBJECT UNSELECT IDLE STARTTLS AUTH=PLAIN A CAPABILITY response is: * CAPABILITY IMAP4 IMAP4rev1 ACL NAMESPACE CHILDREN SORT QUOTA THREAD=ORDEREDSUBJECT UNSELECT IDLE STARTTLS AUTH=PLAIN but hello message is: * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE STARTTLS AUTH=PLAIN] Dovecot ready.

[Dovecot] HA Dovecot Config?
by dovecot＠corwyn.net 23 Oct '09

23 Oct '09

Hi! I'm currently running Dovecot 1.1.8 on a HP server using CentOS 5.2 as my IMAP server, receiving mail from postfix, and also using squirrelmail as the frontend. As I look at upgrading the mail server, I'd like to change to a higher availability configuration (where the server can fail and I don't have to reconfig my imap users). For the SMTP that's easy, because I can use multiple MX records, and I can redirect a port forward from one server to another. But IMAP doesn't have the same functionality, because it's the storage that matters. What's the "best" way to do that? Clustered servers using a SAN? NAS? some sort of appliance in front? Suggestions? Thanks! Rick Rick Steeves http://www.sinister.net In reality nothing is more damaging to the adventurous spirit within a man than a secure future - Alexander Supertramp

[Dovecot] Need a little shadow to MySQL conversion help
by Marc Perkel 22 Oct '09

22 Oct '09

Excuse me for being stupid and confused. I'm trying to convert my dovecot install from passwd-file to mysql. I have a single table called "users" that has 3 fields, user_name, domain_name and password. The data came from passwd/shadow files so it uses the same password encryption as the shadow files do. The directory where the email is stored is calculated elsewhere and not stored in the database. The UID and GID are both mail for all virtual users. The user logs in passing the full email address and the password. So - what would be the config for using MySQL? Do I even need a userdb? If so - what would it be? Thanks in advance.

[Dovecot] VZW Blackberry BIS problems?
by B. Cook 22 Oct '09

22 Oct '09

Ever since Columbus day things have been strange with my two dovecot servers, according to my Blackberry users. We do not have a BES just the standard BIS that comes with a personal account. Several people have told me that since that Monday that they get occasional duplicate copies of messages which only appear singularly in their Maildir inboxes. I myself even called VZW and got transferred to RIM themselves where they 'reset' my account; (same as me going into the BIS server and deleting and adding again) only to have the same thing happen; again occasionally.. Below is relevant dovecot info.. -r-xr-xr-x 1 root wheel 164064 Oct 1 17:16 /usr/local/sbin/dovecot (date it was built; prior to any problems.. *whew*) ;) 1 # 1.2.4: /usr/local/etc/dovecot.conf 2 # OS: FreeBSD 7.2-RELEASE-p3 i386 3 ssl_cert_file: /usr/local/etc/lighttpd/ssl/mail.poughkeepsieschools.org.pem 4 ssl_key_file: /usr/local/etc/lighttpd/ssl/mail.poughkeepsieschools.org.pem 5 disable_plaintext_auth: no 6 verbose_ssl: yes 7 login_dir: /var/run/dovecot/login 8 login_executable: /usr/local/libexec/dovecot/imap-login 9 login_greeting: mail.poughkeepsieschools.org OK 10 first_valid_uid: 89 11 last_valid_uid: 89 12 first_valid_gid: 89 13 last_valid_gid: 89 14 maildir_copy_preserve_filename: yes 15 mail_plugins: quota imap_quota 16 imap_client_workarounds: delay-newmail outlook-idle tb-extra-mailbox-sep 17 auth default: 18 mechanisms: plain login 19 user: vpopmail 20 passdb: 21 driver: vpopmail 22 userdb: 23 driver: vpopmail 24 socket: 25 type: listen 26 client: 27 path: /var/run/dovecot/auth-client 28 mode: 438 29 plugin: 30 quota: maildir:User quota 31 expire: Trash 7 Spam 30 Now what does not show here is something that I put in that it looked like it was supposed to help but didn't.. mailbox_idle_check_interval = 30 after looking around at other people complaining about BIS and possible dovecot issues it seemed that that entry was the 'magic' the BIS was missing; except I never had it and never had troubles. I'm assuming this is a BIS issue of some sort, but I can't tell. After looking on the wiki I didn't see anything that says "BIS users look here for tips.. " So I'm assuming there aren't any; I think it should just work with the IMAP server.. Any help would be appreciated as everyone thinks this is 'our problem' and "if we had an exchange server we wouldn't be having these problems.." Thanks in advance..

I rebuilt the binaries on our hosts with optimization disabled, and I'm still waiting for it to reoccur so I can gather file descriptor information and a core. I don't have the leak-detect patch applied. Let's see what Timo has to say about that log file bit.

[Dovecot] NFS random redirects
by Thomas Hummel 22 Oct '09

22 Oct '09

Hello, Dovecot documentation states that the "random redirects to multiple servers" NFS solution is to be avoided and I'm investigation the actual risks of it and a way to put it to test. I'm running dovecot-1.2.6 with Maildir (indexes, mailboxes and control files are all on NFS) and I'm using procmail instead of deliver as the LDA. 1. Documentation says : "Dovecot locks the maildir while doing modifications to it or while looking for new messages in it" and then mention the "dovecot-uidlist.lock" dotlock file. a) if that file fcntl'ed in addition (i.e. dotlocked + fcntled or just dotlocked) ? b) is that file THE way to lock the Maildir mentionned above or is it just something else used only for updating that particular file (i.e. is Maildir locked in some way + dovecot-uidlist.lock created or just dovecot-uidlist.lock created) ? 2. Documentation says : "NFS caching is a big problem when multiple computers are accessing the same mailbox simultaneously" I guess it's because of the dotlocks files and not fcntl locking ? Is there anything else than dovecot-uidlist which is dotlocked ? If yes, is it dotlocked only or dotlocked and fcntled ? 3. Documentation says : "Dovecot v1.1 flushes NFS caches when needed if you set mail_nfs_storage=yes" How can a program flush the NFS caches ? By which (system) call ? 4. Documentation says : "Besides the NFS cache problems described above, mailbox contents can't be cached as well in the memory either." Is it about in-memory indexes or part of indexes loaded into memory ? 5. How can I torture-test concurrent access to the same mailbox through 2 dovecot servers ? I don't see imaptest.c anymore on http://dovecot.org/tools but I see 2 nfs_test ? Is there some command line options I should use ? 6. when and why can a random redirect to multiple server can cause mailbox corruption ? On flags only or on content as well ?

[Dovecot] deliver+sieve: Destination address (-a) parsing changes
by Frank Behrens 21 Oct '09

21 Oct '09

When I upgraded my old, long running dovecot 1.1 to newer dovecot-1.2.4 + doevecot-sieve- 0.1.12 I observed a change in destination address (-a) parsing. Old behaviour: When Timo introduced this feature (http://www.dovecot.org/list/dovecot/2007-September/025813.html) it was possible to hand over only the detail part. In my sendmail configuration I used "-a +$h", where $h contains the detail part and may be empty. By default sendmail can call the delivery agent with the following information: $u: The recipient user (always set) $h: Detail part, may be empty $g: The sender address (relative to the recipient). New behaviour: The current sieve version needs a complete address with local- and domain-part. Otherwise we get a warning like deliver(user): sieve: envelope recipient address 'user' is unparseable. The problem is, that the domain part is not always available, e.g. for local delivered emails. This is the main problem, although the setup could be simplified if deliver would accept the old syntax. I'm going to make modifications to sendmail to be able to have all address information available, but this will not solve the problem with missing domain. Now comes my question: Is it better to enhance the address parsing in sieve plugin or should I use a wrapper around deliver? The latter is not very difficult, but introduces an additional process (that may fail). Regards, Frank -- Frank Behrens, Osterwieck, Germany PGP-key 0x5B7C47ED on public servers available.

[Dovecot] Question about IMAP IDLE (and Palm Pre)

Hello, i try to understand, how it works (IDLE). Try to get it successfully work with my new Palm Pre ;-) which looks like to have a lot issues wir imap... so i'll blame not dovecot for the issues. Sent a mail, from googlemail. processed by dovecot ad 12:11. what me now confusing, is, that there in the out-log is nothing visible, I expected, to see there was sent an notification, there was a new mail.

[Dovecot] Unknown setting: driver
by Rodolfo González González 19 Oct '09

19 Oct '09

Hi, the conversion from courier was done without problems, but now I have a problem with my auth config. I followed the sql example included in the latest dovecot source, and put driver=mysql in dovecot.conf (outside any section), and now I get: --- Error: Error in configuration file /usr/local/etc/dovecot.conf line 50: Unknown setting: driver Fatal: Invalid configuration in /usr/local/etc/dovecot.conf Starting DovecotError: Error in configuration file /usr/local/etc/dovecot.conf line 50: Unknown setting: driver Fatal: Invalid configuration in /usr/local/etc/dovecot.conf --- So I'm lost... what's wrong? if I followed the example :o Then, another question: I had to go back to courier so my users still can work, but I already created the files using the migration script: do I need to rerun the migration script? or what do I need to do when I manage to fix the error above and run dovecot? Thanks.

[Dovecot] clarify 'type', 'executable' & 'path' in 2.0 master.conf?
by PGNet Dev 19 Oct '09

19 Oct '09

@2.0's master.conf, there's, e.g., service config { type= config executable =config unix_listener { path = config mode = 0666 } } can someone please explain function/usage for the 'type', 'executable' & 'path' fields? and, for any file paths, are the presumed to be _relative_ to the dovecot executable? in $PATH? can they accept full/absolute paths? thanks.

[Dovecot] Dovecot deliver with AD LDAP userdb
by Mark Schaub 19 Oct '09

19 Oct '09

Good Afternoon, I have my virtual users stored in an Active Directory database. As far as mail info goes the 2 important fields are: mail (their primary email address) and otherMailbox (a multivalue attribute containing their mail aliases). Right now all email addresses belong in the same domain and there are no immediate plans to change this. If I use Postfix to do the lookups and delivery only using Dovecot for passdb Pam driver and a static userdb then everything delivers fine to mail and otherMailbox addresses. I have been working on switching over to Dovecot's deliver process in order to integrate sieve capability. I have configured userdb ldap and passdb ldap in Dovecot and have set up master and client sockets. Before I describe my problem let me show you my configuration (as I think the dovecot-ldap.conf in particular needs to be explained). Here are the important parts of dovecot.conf: auth default { socket listen { master { path = /usr/var/run/dovecot/auth-master mode = 0666 user = vmail group = vmail } client { path = /var/spool/postfix/private/auth mode = 0666 user = postfix group = postfix } } passdb ldap { args = /etc/dovecot-ldap.conf } userdb ldap { # Path for LDAP configuration file, see doc/dovecot-ldap-example.conf args = /etc/dovecot-ldap.conf } and my dovecot -n: lda: postmaster_address: postmaster(a)sau24.org mail_plugins: sieve auth default: mechanisms: plain login debug: yes passdb: driver: ldap args: /etc/dovecot-ldap.conf userdb: driver: ldap args: /etc/dovecot-ldap.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 438 user: postfix group: postfix master: path: /usr/var/run/dovecot/auth-master mode: 438 user: vmail group: vmail plugin: sieve: ~/.dovecot.sieve sieve_dir: ~/sieve sieve_storage: ~/sieve Further, here is my dovecot-ldap.conf: hosts = delldb.sau24.org:3268 base = dc=sau24, dc=org ldap_version = 3 dn = cn=Mail User,cn=Users,dc=sau24,dc=org dnpass = secret auth_bind = yes scope = subtree user_attrs = sAMAccountName=home=/home/vmail/%$,=uid=501,=gid=501 pass_attrs = sAMAccountName=user user_filter = (&(objectclass=person)(|(sAMAccountName=%n)(mail=%n@sau24.org)(otherMailbox=%n@sau24.org))) pass_filter = (&(objectclass=person)(|(sAMAccountName=%n)(mail=%n@sau24.org)(othermailbox=%n@sau24.org))) Now, you'll notice that the user_filter and pass_filter have the domain statically placed after the mail and othermailbox attributes. This reason for this is that this ldap configuration is used for both authentication purposes and local delivery, so its not always being passed the domain info (for authentication it gets the users IP address). Since all my users are on the same domain I can statically set this here. This setup authenticates users to imap and pop (users use their sAMAccountName as their username when they log in), and pulls their correct home directory. Checking mail is not a problem at all. Further, this setup will deliver mail correctly to mail addressed to the value in the "mail" attribute. The problem seems to be in the otherMailbox attribute, it cannot lookup the users sAMAccountName based off of the otherMailbox field. Here is what it looks like in the logs for mail sent to my "mail" attribute (mark.schaub(a)sau24.org) Oct 14 12:36:19 auth(default): Info: master in: USER 1 mark.schaub(a)sau24.org service=deliver Oct 14 12:36:19 auth(default): Info: ldap(mark.schaub(a)sau24.org): user search: base=dc=sau24, dc=org scope=subtree filter=(&(objectclass=user)(|(sAMAccountName=mark.schaub)(mail=mark.schaub@sau24.org)(otherMailbox=mark.schaub@sau24.org))) fields=sAMAccountName Oct 14 12:36:19 auth(default): Info: ldap(mark.schaub(a)sau24.org): result: sAMAccountName(home=/home/vmail/%$)=/home/vmail/mschaub Oct 14 12:36:19 auth(default): Info: master out: USER 1 mark.schaub(a)sau24.org home=/home/vmail/mschaub uid=501 gid=501 Oct 14 12:36:19 deliver(mark.schaub(a)sau24.org): Info: sieve: msgid=<6b71e3a70910140936v4e8cd6fdwd847a1721a9d9786(a)mail.gmail.com>: stored mail into mailbox 'INBOX' But this is what I get when I try to send to an address listed in my otherMailbox field (tech(a)sau24.org) Oct 14 12:30:58 auth(default): Info: master in: USER 1 tech(a)sau24.org service=deliver Oct 14 12:30:58 auth(default): Info: ldap(tech(a)sau24.org): user search: base=dc=sau24, dc=org scope=subtree filter=(&(objectclass=user)(|(sAMAccountName=tech)(mail=tech@sau24.org)(otherMailbox=tech@sau24.org))) fields=sAMAccountName Oct 14 12:30:58 auth(default): Info: ldap(tech(a)sau24.org): Unknown user Oct 14 12:30:58 auth(default): Info: master out: NOTFOUND 1 As a test I tried modifying my dovecot-ldap.conf to use different fields instead of otherMailbox. Sending to some of those attributes worked, others didnt. I could use the "sn" and "givenName" attributes, but "postalCode" and "title" would give the same error as otherMailbox. My question is this: is there something wrong with my configuration or can Dovecot only query certain fields in the user_attr string? Thanks, ~ Mark

[Dovecot] Released Sieve v0.1.13 for Dovecot v1.2.6
by Stephan Bosch 18 Oct '09

18 Oct '09

Hello Dovecot users, After about a month of silence, I finally release a new version of Pigeonhole Sieve. This release fixes problems in the multiscript support and improves the body extension further towards RFC compliance. The body extension still needs work, however, since some content types still give erroneous results. Changelog Sieve v0.1.13: + Body extension: implemented proper handling of the :raw transform and added various new tests to the test suite. However, :content "multipart" and :content "message/rfc822" are still not working. + Fixed race condition occuring when multiple instances are saving the same binary (patch by Timo Sirainen). + Test suite: added support for testing multiscript execution. - Made compiler more lenient towars missing CRLF at the end of the script in a hash comment. - Body extension: don't give SKIP_BODY_BLOCK flag to message parser, we want the body! (patch by Timo Sirainen). - Fixed handling of implicit side effects for multiscript execution. - Fixed bugs in multiscript support; subsequent keep actions were not always merged correctly and implicit side effects were not always handled correctly. - Fixed a segfault bug in the sieve-test tool occuring when compile fails. - Fixed segfault bug in action procesing. It was triggered while merging side effects in duplicate actions. - Fixed bug in the Sieve plugin that caused it to try to stat() a NULL path, yielding a 'Bad address' error. The release is available as follows: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.13.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.13.tar.gz.sig Refer to http://pigeonhole.dovecot.org for more information. Have fun testing the new release and don't hesitate to notify me when there are problems. Releases for Dovecot v2.0 are still under development... Regards, -- Stephan Bosch stephan(a)rename-it.nl

[Dovecot] migrate courier to dovecot script - questions about directory structure
by Ross 16 Oct '09

16 Oct '09

Hi all, Im in the process of moving about 7000 users across from courier to dovecot. Both Maildir setups. The migration script works a treat, but I need a slight change to it. Couriers directory structure looks ike this: /home/vmail/<domain.com.au>/<username>/cur/ /home/vmail/<domain.com.au>/<username>/new/ /home/vmail/<domain.com.au>/<username>/tmp/ /home/vmail/<domain.com.au>/<username>/maildirsize /home/vmail/<domain.com.au>/<username>/courier* etc.. Dovecot looks like this: /home/vmail/<domain.com.au>/<username>/Maildir/cur/ /home/vmail/<domain.com.au>/<username>/Maildir/new/ /home/vmail/<domain.com.au>/<username>/Maildir/tmp/ So the issue is, there is an additional Maildir directory in the structure. Now the migration script works fine, however when the migration is completed, I have to manually add the Maildir directory into the structure, which is going to take a little too long :) Is there something in the script that can add this ? Is there a way to perhaps use the script to add the Maildir part ? My initial plan was to copy the entire /home/vmail/<domain.com.au>/* across to the dovecot server and run the migration script. However, without the Maildir directory in the structure it won't work. Has anyone run into this issue ? How did you solve it ? -- Regards Ross fatboy:/tmp# dovecot --version 1.0.15 fatboy:/tmp# dovecot -n # 1.0.15: /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login mail_privileged_group: mail mail_location: maildir:/var/vmail/%Ld/%Ln/Maildir mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv namespace: type: private separator: . prefix: INBOX. inbox: yes auth default: mechanisms: plain login passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: passwd userdb: driver: static args: uid=5000 gid=5000 home=/var/vmail/%d/%n allow_all_users=yes socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: vmail plugin: quota: maildir:storage=51200

Re: [Dovecot] Dovecot deliver with AD LDAP userdb [SOLVED]
by Mark Schaub 16 Oct '09

16 Oct '09

> Then there's something different what Dovecot and ldapsearch does. They > have the same dn, dnpass, neither uses tls, same base, deref, scope? > I figured it out, there certainly is something different! The AuthDatabase/LDAP documentation on the Dovecot Wiki says "When connecting to AD, use port 3268". Port 3268 is used for Global Catalog searching. By default the Active Directory Global Catalog wouldn't include attributes like otherMailbox, but would include mail and sn. The solution here would be to either use port 389 and search the domain like ldapsearch or to add the otherMailbox attribute (or any others I want to search on) to the global catalog. It might be worth updating the wiki to mention the reasoning behind using port 3268 and the implications it can cause. Thanks for the help!

[Dovecot] Sendmail and Dovecot Delivery to Virtual Users
by Philipp Hunold 16 Oct '09

16 Oct '09

I'm new to dovecot and sendmail and my server doesn't forward mails to 'dovecot deliver' at all. I was reading http://wiki.dovecot.org/LDA/Sendmail and this http://www.dovecot.org/list/dovecot/2009-June/040353.html from the mailling list but I could figure it out myself. I someone could point me into the right direction. I'm confused with the config for LDA. Basically what I want is every message coming in go to 'deliver' except if there's no dovecot user of course. I'm using 'local_procmail' feature right now, but I tried to comile the dovecot Mailer also. Anyway the dovecot 'deliver' itself works fine. But I cannot receiving emails or messages don't go anywhere. All the debugging I do with telnet right now. first I got 'User Unknown' errors in the maillog so I thought I just missing an alias/virtuser entry. So I create one and forward those to procmail. But now the messages don't go anywhere and the status is sent and I don't seem them in the /var/log/dovecot-deliver.log either, so they are stuck in the middle somewhere. Oct 16 14:26:26 sendmail[29939]: n9GIQQAh029939: to=|/usr/bin/procmail, ctladdr=<mail.address> (8/0), delay=00:00:00, xdelay=00:00:00, mailer=prog, pri=31420, dsn=2.0.0, stat=Sent I don't seem to understand how the message get to dovecot's 'deliver' from sendmail. Some questions I have which may help to solve the problem myself: - how can I tell the LDA to lookup dovecot users too? to it would accept it? - do I need aliases therefore for each dovecot users? - What would the alias look like or is this the wrong way to do it? "test.user: |/usr/bin/procmail" ? - what's the procmail recipe which would work for maildir:/home/vmail/%u mail_location?

[Dovecot] Sieve question
by CJ Keist 16 Oct '09

16 Oct '09

If there is a separate sieve mailing list let me know. But have question if someone else has done this or not. Right now I have web form people use to setup their vacation replies using Sieve (1.1.6). The form alows them to set what they want their reply address to be, whether to send the reply once, weekly or bi-weekly. I would like to setup another option to let them set the date in which to de-active the vacation replies automatically. Right now they have to remember to log back into the form to turn off the vacation reply. Has anyone set something like this up? -- C. J.

If the mailbox is large, it may take time to re-generate index and put lock on inbox file until it's done. However, it should not for smaller mailbox file. Deleting index files did not help. The workaround is rename the mailbox file and copy it to ~/mail folder and let MTA re-create the mailbox. Then let mail client subscribes to the new temp mailbox.

[Dovecot] Dovecot can't find users' sieve files
by Bartosz Fenski aka fEnIo 16 Oct '09

16 Oct '09

Hello. I asked for help on #dovecot but one suggestion I got was setting sieve variable explicitly but unfortunatelly that didn't help. I'm trying to set up sieve to be able to use vacation module. So in the lda section I put: mail_plugins = sieve And in plugins section: sieve = ~/.dovecot.sieve Then I put .dovecot.sieve file in the user's directory. This is what I get in Dovecot's log when trying to deliver to that mailbox: 2009-10-16 18:37:52 deliver(test(a)domain.pl): Error: sieve: stat((null)) failed: Bad address (using global script path in stead) 2009-10-16 18:37:52 deliver(test(a)domain.pl): Info: msgid=<20091016163757.GK19565(a)asdy.pl>: saved mail to INBOX Some infos about system: Dovecot 1.2.5 Debian squeeze/testing x86_64 ext3 (root)~#dovecot -n # 1.2.5: /etc/dovecot/dovecot.conf # OS: Linux 2.6.30-1-amd64 x86_64 Debian squeeze/sid ext3 log_path: /var/log/dovecot.log log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login mail_privileged_group: mail mail_location: maildir:/home/vmail/%u mbox_write_locks: fcntl dotlock mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 lda: postmaster_address: postmaster(a)domain.pl mail_plugins: sieve log_path: /var/log/dovecot-deliver.log auth_socket_path: /var/run/dovecot/auth-master auth default: passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: sql args: /etc/dovecot/dovecot-sql.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: vmail group: vmail plugin: sieve: ~/.dovecot.sieve (root)~# And dovecot-sql.conf: driver = pgsql connect = host=localhost dbname=postfix user=postfix password = xxxxxxxx password_query = \ SELECT local_part, password \ FROM mailbox WHERE local_part = '%n' AND active = 't' user_query = \ SELECT maildir, 5000 AS uid, 5000 gid \ FROM mailbox WHERE local_part = '%n' AND active = 't' Delivering works perfectly but I can't figure out why it's not able to find that .dovecot.sieve file: (root@germany)~#ls -al /home/vmail/test(a)domain.pl/.dovecot.sieve -rw-r--r-- 1 vmail vmail 314 2009-10-16 13:09 /home/vmail/test(a)domain.pl/.dovecot.sieve (root@germany)~# Any help would be very appreciated. regards fEnIo -- ,''`.

[Dovecot] Better APPEND performance
by Mike Abbott 16 Oct '09

16 Oct '09

Moving a large number of messages into an IMAP folder on a dovecot server takes quite a long time. This is a popular operation for users migrating their stored messages from their old mail servers through a mail user agent, and it causes a poor first impression of dovecot. I'd like your help to speed this up. I have studied this problem in recent versions, including 1.1.[17-19] and 1.2.[4-6] but I'll focus on 1.2.6, using Maildir++. It seems to be caused by O(n^2) behavior in maintaining the UID list, where n is the number of messages. The client selects a folder then sends thousands of individual APPEND commands (no use of multiappend unfortunately). These cause dovecot to behave as follows: 1. For every other APPENDed message, dovecot appends the new UID to the list quickly. No problem here, this is fast. 2. For every other other APPENDed message, dovecot scans the entire UID list. This is an O(n) algorithm. Since it happens every n/2 times it causes O(n^2) behavior across n consecutive APPENDs. More specifically, 1. APPEND a message to a folder that already contains 30,000 messages. maildir_uidlist_refresh_fast_init() takes the fast path. 2. APPEND a second message to the same folder. maildir_uidlist_refresh_fast_init() takes the slow path: it populates the uidlist->files hash table with all the UIDs, checking for duplicates. At the end of the command maildir_uidlist_deinit() destroys the hash table. Note how this APPEND takes much longer than #1. 3. APPEND a third message to the same folder. Just like #1. 4. APPEND a fourth message to the same folder. Just like #2, and since #2 destroyed the hash, it has to do all that work over again. 5. And so on. What can be done to make maildir_uidlist_refresh_fast_init() choose the fast path more often?

[Dovecot] v2.0.alpha1 released
by Timo Sirainen 16 Oct '09

16 Oct '09

http://dovecot.org/releases/2.0/alpha/dovecot-2.0.alpha1.tar.gz http://dovecot.org/releases/2.0/alpha/dovecot-2.0.alpha1.tar.gz.sig So here's the first alpha version of Dovecot v2.0. There are still a couple of things left to do, but in general it should work for most people. I started using it for my own mails a few days ago and it seems to work without errors. Largest changes since v1.2: * Global ACLs are now looked up using namespace prefixes. For example if you previously had INBOX. namespace prefix and a global ACL for "INBOX.Sent", it's now looked up from "INBOX.Sent" file instead of "Sent" as before. + Redesigned master process. It's now more modular and there is less code running as root. + Configuration supports now per-local/remote ip/network settings. + dsync utility does a two-way mailbox synchronization. + LMTP server and proxying. + Added mdbox (multi-dbox) mail storage backend. + doveadm utility can be used to do all kinds of administration functions. Old dovecotpw and *view utilities now exist in its subcommands. Some things left to do: - Do something about backwards compatibility with v1.x. Either make it read v1.x config files or provide some config conversion utility. - dsync still has some bugs - config process is a bit too slow. config handling in general could use some caching all around. no need to ask configuration for each login unless there are per-remote-ip settings. - some kind of an optional connection policy server could be useful. mainly to finally implement tcp-wrappers support. - mail_uid, mail_gid, mail_chroot settings don't really work now. I think this actually needs a bit larger change, which is probably a good idea in any case: After successfully authenticating, login process needs to get imap/pop3 process executed. Currently this is done by transferring the connection fd to master process, doing userdb lookup and then forking and execing the imap/pop3 process. The new behavior I'm thinking is that after auth, login process would connect to imap/pop3 unix socket in the login/ directory. That would cause master process to fork a new imap/pop3 process (running as root). Login process would send the necessary auth information via the unix socket, possibly transfer also the fd, and imap/pop3 would do the userdb lookup and then drop privileges. This change has some pros: - Master process will no longer temporarily hold some extra fds and use extra memory during auth lookups. If auth process is hanging these could cause problems. - Master process will no longer have any special auth handling code and I can remove type=auth-source and type=auth services. - Of course fixes the mail_* setting issue, because all of this is now done by imap/pop3 process, which knows about these settings. - Creating support for "multiple imap/pop3 post-login connections in a single process" should be pretty easy to implement with this. The imap/pop3 unix socket just needs to be listened by a new process in the middle that keeps track of what imap/pop3 processes exist and can redirect the new connections to those. But also some cons: - drop_priv_before_exec=yes no longer works, unless the uid/gid is hardcoded to the service {} block. - Each imap/pop3 process needs to do a connect() to auth server at startup, adding a bit to the latency.

[Dovecot] "From" address in vacation response on hosted domains with dovecot/postfix/sieve
by Peter Borg 16 Oct '09

16 Oct '09

Hi, I have a working dovecot/postfix/sieve configuration: Ubuntu 8.04 LTS Dovecot 1.2.6 Sieve 0.1.12 Postfix 2.5.1 The server is configured to host multiple domains. All mail delivery, logins and aliases work absolutely perfectly. There's only one weirdness: the 'From' address in vacation responses. If a message is sent to user(a)hosteddomain.com the response comes from user-hosteddomain.com(a)hostingservername.com Obviously it's doing what one would expect in that it's taking the username (user-hosteddomain.com) and appending the local host name (hostingservername.com) This isn't great from the perspective of the hosted user, however, who'd much rather their vacation message was sent from their actual email address. Clearly I can modify this by using a ':from' statement in each relevant sieve file, but I can't rely on users' mail clients to set this (as not all do) and the webmail client in use on the server doesn't set this. I can almost certainly implement some kind of hack using this, but I'd rather not. So how does sieve determine the from address to use if it's not explicitly set in the sieve script for the user, and how can I direct sieve to determine the address differently, preferably with a central configuration option that will apply to all users regardless of domain.....? Regards, Peter.

[Dovecot] Internal server
by Guy 16 Oct '09

16 Oct '09

Hi, I'm looking at doing some testing for a little internal IMAP server. Basically use fetchmail (or some such thing to bring in mail) so users have a local IMAP server to connect to. I'm interested in trying out mdbox, but since I'd have to use dovecot 2.0 with it I thought I'd just check what peoples' experience with 2.0 is like so far? Is it reasonably stable already? Is there also a page showing the differences in config for dbox over maildir? Or is it simply just the change in mail_location and nothing else? Thanks Guy -- Don't just do something...sit there!

[Dovecot] Expire plugin: wrong mailbox separators in database?
by Andreas Ntaflos 16 Oct '09

16 Oct '09

Hi all, I'm experimenting with the expire plugin and seem have run into a small problem. I am using Dovecot 1.2.4 on a test server. The config is taken mostly verbatim from the expire plugin wiki page [1], using MySQL as a database. See below for detailed output. Namespace "private" has "/" configured as mailbox separator: namespace private { separator = / prefix = inbox = yes } The "expire =" section from dovecot.conf thus looks like this: plugin { expire = Trash 7 INBOX/Spam 8 INBOX/Spam/To-Discard 3 ... } Three mailboxes/folders are kept track of: Trash, INBOX/Spam and INBOX/Spam/Spam-To-Discard (this one holds messages that scored high enough to very unlikely be legitimate and should be deleted soon). But when a message is put into one of these folders the mailbox attribute of the expires table uses "." as mailbox separator: mysql> select * from expires; +-----------------+----------------------------+--------------+ | username | mailbox | expire_stamp | +-----------------+----------------------------+--------------+ | foo(a)example.org | INBOX.Spam.Spam-To-Discard | 1253114526 | | foo(a)example.org | INBOX.Spam | 1253114528 | +-----------------+----------------------------+--------------+ Consequently, expire-tool --test seems to choke on this: # dovecot --exec-mail ext /usr/local/libexec/dovecot/expire-tool --test Info: foo(a)example.org/INBOX.Spam.Spam-To-Discard: \ mailbox 'INBOX.Spam.Spam-To-Discard' removed from config Info: foo(a)example.org/INBOX.Spam: mailbox 'INBOX.Spam' \ removed from config When I manually update the mailbox attribute to use "/" as separator expire-tool seems to work correctly: # dovecot --exec-mail ext /usr/local/libexec/dovecot/expire-tool --test Info: foo(a)example.org/INBOX/Spam/Spam-To-Discard: stop, expire \ time in future: Wed Sep 16 17:22:06 2009 Using "." as separator in the "expire =" line doesn't work either: the expires table isn't written to at all when a message is put in one of the specified folders. Presumably because INBOX/Spam is the real mailbox but INBOX.Spam is monitored by the expire plugin and there is no INBOX.Spam to put in messages. So I believe this is not the expected behaviour? Or am I doing anything wrong? I'd rather not change the separator from "/" to "." in all the namespaces if that can be avoided.

[Dovecot] Error (IMHO) with --with-doc option
by Jacek Osiecki 16 Oct '09

16 Oct '09

Hi, I was trying to create complete rpm package for my system, containing dovecot 1.2.5 intregrated with dovecot-sieve and dovecot-managesieve. Finally I succeeded and it works great, but I found something that might be treated as wrong behaviour... When you run ./configure --with-docs=no, Makefile does not build docs anymore, but... installs them anyway :) It caused some troubles because rpmbuild complained about documents moved to <buildroot>/usr/share/doc/dovecot I have created a small patch that fixes this - hope it doesn't introduce any mess: diff -Nur 2/Makefile.in 1/Makefile.in --- 2/Makefile.in 2009-09-29 00:17:22.000000000 +0200 +++ 1/Makefile.in 2009-09-29 00:17:38.000000000 +0200 @@ -75,7 +75,7 @@ distclean-recursive maintainer-clean-recursive ETAGS = etags CTAGS = ctags -DIST_SUBDIRS = src doc +DIST_SUBDIRS = $(SUBDIRS) DISTFILES = $(DIST_COMMON) $(DIST_SOURCES) $(TEXINFOS) $(EXTRA_DIST) distdir = $(PACKAGE)-$(VERSION) top_distdir = $(distdir) Best regards, -- Jacek Osiecki joshua(a)ceti.pl GG:3828944 I don't want something I need.

[Dovecot] Questions regarding dbox migration
by Mikkel 16 Oct '09

16 Oct '09

It has been my wish to move to dbox for a long time hoping to reduce the number of writes which is really killing us. Now I wonder what may be the best way of doing so. I'm considering some sort of intermediate migration where the existing Maildir users are changed to single-dbox and then later upgraded to 2.0 and changed to multi-dbox when it becomes stable. But is this a reasonable task to perform on a production system or at all? The alternative is to wait for 2.0 to become completely stable and then go all the way at once. I would however much prefer to take it one step at a time and I think it would be safer to start out with single-dbox as it appears less complex. Now the big question is whether multi-dbox and single-dbox are compatible formats. If a Maildir->dbox migration is made on a system running dovecot v. 1.1, would it then be trivial later changing to multi-dbox after upgrading to 2.0 or is a completely new migration then needed? Would this scenario be much different if the system is upgraded to version 1.2 before the change to single-dbox? Kind regards, Mikkel

[Dovecot] dovecot 1.2.6 fails to build with openssl < 0.9.8
by Paul Howarth 16 Oct '09

16 Oct '09

The update of ssl_proxy_get_security_string() in dovecot 1.2.6 has broken compatibility with openssl < 0.9.8 (e.g. on RHEL4) because the functions SSL_COMP_get_name and SSL_get_current_compression don't exist until openssl 0.9.8 (build fails at link time due to these symbols being unresolved). I've worked around this by reverting the function to the 1.2.5 version for now but I think a better solution would be to have a configure test for these functions and only include the SSL compression details when they're available. Cheers, Paul.

[Dovecot] is it possible to fetch messages for multiple users using a single account?
by Tony Smith 16 Oct '09

16 Oct '09

Dear list, I am running dovecot with LDAP. Each account has email in form abc(a)example.com, and messages are stored at /var/vmail/abc/Maildir. This is an external mail server, and I would like to use a cron job to fetch all messages to an internal server which has slow internet connection. It seems getmail supports multidrop retriever which might fit the bill. However I could not figure out how to set up an account that can be used to fetch all messages for all virtual accounts. Is it possible at all? thanks, Tony PS: here is my config: # dovecot -n # 1.1.13: /etc/dovecot/dovecot.conf # OS: Linux 2.6.26-2-openvz-amd64 i686 Debian 5.0.3 log_path: /var/log/dovecot.log protocols: pop3 pop3s imap imaps managesieve listen(default): * listen(imap): * listen(pop3): * listen(managesieve): 127.0.0.1:2000 ssl_cert_file: /etc/ssl/certs/cert.pem ssl_key_file: /etc/ssl/private/key.pem disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login login_executable(managesieve): /usr/lib/dovecot/managesieve-login mail_uid: 1000 mail_gid: 1000 mail_location: maildir:/%Lh/Maildir/:INDEX=/%Lh/Maildir/ mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_executable(managesieve): /usr/lib/dovecot/managesieve mail_plugins(default): quota imap_quota zlib mail_plugins(imap): quota imap_quota zlib mail_plugins(pop3): quota zlib mail_plugins(managesieve): mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 mail_plugin_dir(managesieve): /usr/lib/dovecot/modules/managesieve pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh pop3_client_workarounds(managesieve): sieve_storage(default): sieve_storage(imap): sieve_storage(pop3): sieve_storage(managesieve): /var/vmail/sieve/%Ld/%Ln/ sieve(default): sieve(imap): sieve(pop3): sieve(managesieve): dovecot.sieve auth default: mechanisms: plain login default_realm: river-valley.com user: vmail passdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf userdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf socket: type: listen client: path: /var/spool/postfix/dovecot-auth mode: 438 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 438 user: vmail group: vmail plugin: quota_warning: storage=85%% /usr/bin/dovecot-quota-warning.sh 85 quota_warning2: storage=90%% /usr/bin/dovecot-quota-warning.sh 90 quota_warning3: storage=95%% /usr/bin/dovecot-quota-warning.sh 95 quota: maildir quota_rule: *:storage=100M expire: Trash 7 Trash/* 7 Junk 30 expire_dict: proxy::expire auth_socket_path: /var/run/dovecot/auth-master dict: expire: db:/var/lib/dovecot/expire/expire.db

[Dovecot] virtual Folder Plugin with "." Separator: [NONEXISTENT] Mailbox doesn't exist
by Elmar Weber 15 Oct '09

15 Oct '09

Hello, I've switched from courier-imap to dovecot to benefit from the virtual folder feature. I'm using dovecot 1.2.6 on Gentoo Linux. However, I', getting the message "[NONEXISTENT] Mailbox doesn't exist: <name>" from Thunderbird when I try to access any virtual folder. The relevant setup: mail_location = maildir:~/.maildir namespace private { separator = . inbox = yes hidden = yes list = yes } namespace private { prefix = virtual. separator = . location = virtual:~/.maildir/.virtual } I then created the folders ~user/.maildir/.virtual and ~user/.maildir/.virtual.test and placed a file in .virtual.test with the contents ====== * all ====== After a dovecot restart I'm getting the error message: "[NONEXISTENT] Mailbox doesn't exist: test" Where did I make the mistake in the configuration? Is the "." path separator a problem case? ciao, Elmar

[Dovecot] Missing folders
by John Moorhouse 15 Oct '09

15 Oct '09

I've recently had a oops with the system I was running dovecot on so have had to move it to a new machine, I've been able to retrieve the mbox files from the old machine, built the new machine and over wrote the new mbox files with the old one in maildir, connecting to the server via imap woeks but I can only see the mail in the inbox from the old mbox files, emails in sub directories (the sub directories arn't there), is there some command I need to run to get it to pass the mbox file to find the folders or it there another file I need to transfer form the old machine. (I'm assuming that all the emails for a user, including those in subfolders are within the single mbox file, particularly as I'm is very large) Thanks John

[Dovecot] Dovecot lock problem
by Simon Gao 15 Oct '09

15 Oct '09

Hi, We have a few users experiencing locking problem. When starting Thunderbird, there is no new emails in Inbox. Dovecot createa a lock file /var/spool/mail/<user>.lock. It never completes openning Inbox. If closing the mail client, the open imap session does not get closed, nor the lock file get deleted. Here are the errors in log: dovecot: Oct 13 11:18:35 Warning: IMAP(user1): Our dotlock file /var/mail/user1.lock was deleted (kept it 88 secs) dovecot: Oct 13 11:18:35 Error: IMAP(user1): file_dotlock_delete() failed with mbox file /var/mail/user1: No such file or directory We are running Dovecot 1.1.2. Any pointer to resolve this problem is appreciated. Simon

[Dovecot] MailDIR and expire plugin
by Jerry 15 Oct '09

15 Oct '09

All of the mailboxes on this system are in MailDIR format. None of the users delete mail off of the server after POPing their accounts. This is the present setting: expire = Trash 7 Spam 30 expire_dict = proxy::expire Is that correct for MailDIR style mailboxes? It doesn't appear correct; however, I have not been able to find any specific documentation on expire with MailDIR style mailboxes. I am assuming that the expire plugin will work since IMAP has not been implemented on this server. -- Jerry |::::======= gesbbb(a)yahoo.com |::::======= |=========== |=========== | QOTD: "Wouldn't it be wonderful if real life supported control-Z?"

[Dovecot] Dovecot 1.2.6 segfault in imap_fetch_begin
by Brandon Davidson 15 Oct '09

15 Oct '09

We recently upgraded from Dovecot 1.2.4 to 1.2.6 (with the sieve patches of course). Everything has been running quite well since the upgrade. The occasional issue with assert-crashing when expunging has gone away. However, one of our users seems to have triggered a new issue. She's been the only one to see it, but whenever she logs in, her imap process segfaults immediately. It appears that the crash is a null pointer deref in the array library, but I'm not sure what code is at fault for calling in without checking array validity... or even if I'm on the right track. Backtraces and some further information are available here. Cores available on request. http://uoregon.edu/~brandond/dovecot-1.2.6/bt.txt Thanks, -Brad

[Dovecot] Deliver - can't connect to .../auth-master
by iain＠brightbooks.co.uk 15 Oct '09

15 Oct '09

Dovecot version 1.1.11 Hi all, I'm having real trouble getting Getmail, which is configured to pick up mail from my ISPs mailhost, to put the mail in our local Maildirs, through Deliver. We're using virtual users so, if I am understanding correctly, Deliver needs to fetch this information from /var/run/dovecot/auth-master. The trouble is that Deliver doesn't seem to have the correct privileges to do so. Whenever Getmail tries to pass the mail to Deliver, the line: Oct 15 15:21:04 Domain deliver(user(a)domain.com): Can't connect to auth server at /var/run/dovecot/auth-master: No such file or directory appears in the Mail.err log. So far I've tried: # - Changing the privileges of the whole /var/run/dovecot/ folder, and its sub folders. I understand that this is only a workaround, as Dovecot changes the privileges back on restart, however it doesn't seem to work anyway. It changes the log result from 'No such file or directory' to 'Permission denied' (and sometimes 'Connection refused'). # - I tried setting the location of auth-master to /home/manager/dovecot in the dovecot-postfix.conf config files (and the dovecot.conf config, just in case), so I could control access to it, and its permissions, more closely. Again, no luck. The log file still shows that it is trying to access it through /var/run/dovecot ~ not sure why (I even went to the lengths of doing a search for /var/run/dovecot in the config files, to make sure I hadn't missed a rogue mention; nothing). Interestingly the file auth-master is created in the correct folder I've configured, but the log results still stay the same. Thanks in advance for any help getting this up and running.

[Dovecot] Two passwords: One for Dovecot IMAP and One for Dovecot SASL? Is it possible?
by Art Gray - Razorpoint 15 Oct '09

15 Oct '09

Greetings, Can Dovecot can handle separate authentication for receiving mail (IMAPS) and sending mail (SMTPS)? In the past, we used Dovecot IMAP for the receiving part and Cyrus SASL for the sending part. This allowed us to use two passwords with mail. Cyrus has grown too old and isn't useful anymore. Can Dovecot give us this functionality: two passwords, one for IMAP authentication and one for SASL authentication? If so, could you point me in the right direction to get this working? Thanks in advance, A

My configuration: # 1.2.4: /etc/dovecot.conf # OS: Linux 2.6.18-128.7.1.el5xen x86_64 CentOS release 5.3 (Final) ext3 protocols: imap imaps pop3 pop3s managesieve listen(default): *, [::] listen(imap): *, [::] listen(pop3): *, [::] listen(managesieve): *:20000 login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login login_executable(managesieve): /usr/libexec/dovecot/managesieve-login login_greeting: Server ready. login_process_per_connection: no verbose_proctitle: yes first_valid_uid: 1 first_valid_gid: 90 last_valid_gid: 400 mail_privileged_group: mail mail_location: maildir:/home/%u/Maildir:INDEX=MEMORY:CONTROL=/conf/no-quotas/control/%u mail_debug: yes mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_executable(managesieve): /usr/libexec/dovecot/managesieve mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugins(managesieve): mail_plugin_dir(default): /usr/lib64/dovecot/imap mail_plugin_dir(imap): /usr/lib64/dovecot/imap mail_plugin_dir(pop3): /usr/lib64/dovecot/pop3 mail_plugin_dir(managesieve): /usr/lib64/dovecot/managesieve imap_client_workarounds(default): delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(imap): delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(pop3): imap_client_workarounds(managesieve): pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh pop3_client_workarounds(managesieve): lda: postmaster_address: postmaster(a)example.com mail_plugins: quota sieve auth_socket_path: /var/run/dovecot/auth-master auth default: debug: yes passdb: driver: ldap args: /etc/dovecot-ldap.conf userdb: driver: ldap args: /etc/dovecot-ldap.conf socket: type: listen master: path: /var/run/dovecot/auth-master mode: 511 plugin: quota: maildir trash: /etc/dovecot-trash.conf sieve: ~/.dovecot.sieve sieve_dir: ~/sieve sieve_extensions: +imapflags +notify dovecot-ldap.conf: hosts = ldap.example.com auth_bind = yes base = ou=people, dc=example, dc=com scope = subtree user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid,telephoneNumber=quota_rule=*:storage=%$M user_filter = (&(objectClass=posixAccount)(uid=%u)) pass_attrs = uid=user,userPassword=password pass_filter = (&(objectClass=posixAccount)(uid=%u)(!(shadowExpire=*))) default_pass_scheme = CRYPT Imap shows correct quota, but dovecot lda doesn't reject mail and it gets overquota, maildirsize: 15728640S 28033743 4 If I add for example quota_rule = *:storage=20M to dovecot.conf it works, but I need per-user ldap quotas. It seems dovecot deliver ignores maildirsize.

[Dovecot] Investigating suspected cache corruption
by David Warden 14 Oct '09

14 Oct '09

Hi All, I'm running Dovecot 1.1.11 for a site of about 7000 active users with a Squirrelmail frontend. We migrated from Courier (big shout to everyone who worked on the wonderful part of the Dovecot wiki that deals with Courier migration) and I have been extremely happy with the performance gains Dovecot has given us. Not only is the IMAP part of Squirrelmail faster, but our same hardware is under far less stress than it was before the migration. To date, the only problem we have experienced is a seemingly random but significant slowdown in Squirrelmail's loading of the messages in a user's Inbox. Each time, I have been able to fix the problem by deleting the user's dovecot.index, dovecot.index.cache and dovecot.index.log files in the user's INDEX directory for their dovecot Inbox. I tried having users experiencing this problem log in to a test Squirrelmail box with mail_debug on, but I didn't see anything out of the ordinary and they report the same slowness on the test server. I don't see anything but normal login/logout IMAP lines in the production dovecot logs. I have hesitated a bit in posting to the list since this seems to be happening to a small percentage of users and it technically may be a problem with Squirrelmail, but the fact that I'm able to fix the problem by nuking Dovecot's index files has me concerned - does anyone have any suggestions for troubleshooting? My first idea when I get another one of these is to do a telnet IMAP session to Dovecot on one of the Squirrelmail boxes and see if I can get it to slow down when retrieving messages from the Inbox. We are using Maildir over NFS with the control/index files stored on NFS as well. We're doing FS quota over NFS using rquotad to query the NFS server for each user's quota. Here's the output of dovecot -n: # 1.1.11: /etc/dovecot.conf Warning: fd limit 1024 is lower than what Dovecot can use under full load (more than 1536).

[Dovecot] quota error dovecot 1.1.13
by Brightblade 14 Oct '09

14 Oct '09

Hi all, I've troubles with dovecot and quota. Sometimes mails to users are bounced because quota is full. I'm reading quota_rules from LDAP. One "du -h ." from maildir show user is under quota ( at 70 % more or less), less than 99%, i delete maildirsize and dovecot recreate it with ldap-quota value at first line and second line is current-quota mails. Current-quota is near quota max value so dovecot execute quota_warning (99%). Why is dovecot thinking quota is at 99% when du -h show me its value is near 70% ? any guess?

[Dovecot] backup using rsync
by Scott Murman 14 Oct '09

14 Oct '09

i'm trying to backup the dovecot Maildir files over a cifs share. source is a debian build, share is a readynas. i've been getting rsync: mkstemp 'filename goes here' failed: Not a directory (20) errors. rsync is v3.0. i believe this is related to the dovecot file naming convention that includes characters such as ':' in the filename. anyone else seeing similar behavior? a workaround? i can go to different backup strategies, but rsync is cheap and effective for my needs. thanks, -SM-

[Dovecot] Homedir for sieve/LDAP
by Edgar Fuß 13 Oct '09

13 Oct '09

I'm somewhat confused regarding Home Directories needed by sieve and setting them for an LDAP userdb. We have system users, passdb ldap, userdb ldap, but home directories are not mounted on the mail server. Now apparently, sieve needs the home directory for .dovecot.lda-dupes. Is there an easier way to give lda/sieve a home directory than setting something along the lines of user_attrs = ...,uid=home=/import/mail/%$/home in dovecot-ldap.conf?

[Dovecot] failing to deliver to one of multiple destinations
by Edgar Fuß 13 Oct '09

13 Oct '09

Is it defined whether, in case a message should be delivered to multiple destinations via a sieve script, and one of those destinations fail, then the whole delivery is to be considered as successful or not? My case: A sieve script forwarding to and external destinations plus local keep. The keep fails (configuration error, wrong homedir, .dovecot.lda- dupes not writable). According to postfix logs, dovecot deliver returned success. The mail was NOT delivered to the local destination and NOT bounced. Is this expected behaviour?

[Dovecot] LAYOUT=fs still uses 'dot' prefixes for folders

13 Oct '09

running latest dovecot HEAD, per, http://wiki.dovecot.org/MailLocation/Maildir i've set LAYOUT=fs, dovecot -n| grep -i layout mail_location: maildir:/data/mail:LAYOUT=fs and expect, maildirs to actually use physical directories, such as: * Maildir/folder/ * Maildir/folder/subfolder/ but, autocreate@login creates folders using "dot" prefixes, e.g., cd /data/mail/Domains/my.domain.com/Accounts/test_account ls -1d .* ./ ../ .Drafts/ .Spam/ .Templates/ .Trash/ &, login via TBird, creating a folder "test", also creates .test/ a bug, or a misconfiguration?

[Dovecot] (no subject)
by Jerry 13 Oct '09

13 Oct '09

Using Postfix with Virtual Users/Virtual Domains, I have configured it with a wild card entry; i.e., "*.mydomain.com" This works fine in Postfix; however, using Dovecot for delivery is causing the message to bounce since Dovecot does not have an entry in the "user passwd" or "userdb" file. I want to store the catch-all addresses in a separate mailbox. Can I use sieve for this or will that fail also? This is the entry in the postfix master.cf file: dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/local/libexec/dovecot/deliver -f ${sender} -d ${user}@${nexthop} The output of dovecot -n # 1.2.4: /usr/local/etc/dovecot.conf # OS: FreeBSD 7.2-STABLE i386 ufs log_path: /usr/home/gerard/dovecot.log protocols: pop3 pop3s managesieve listen(default): * listen(pop3): * listen(managesieve): localhost:2000 disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/local/libexec/dovecot/pop3-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login login_executable(managesieve): /usr/local/libexec/dovecot/managesieve-login login_greeting: Greetings From Seibercom.net verbose_proctitle: yes first_valid_uid: 1000 first_valid_gid: 1000 mail_privileged_group: mail mail_location: maildir:/var/mail/vhost/%d/%n mail_executable(default): /usr/local/libexec/dovecot/pop3 mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_executable(managesieve): /usr/local/libexec/dovecot/managesieve mail_plugins(default): expire mail_plugins(pop3): expire mail_plugins(managesieve): mail_plugin_dir(default): /usr/local/lib/dovecot/pop3 mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 mail_plugin_dir(managesieve): /usr/local/lib/dovecot/managesieve pop3_client_workarounds(default): outlook-no-nuls oe-ns-eoh pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh pop3_client_workarounds(managesieve): dict_db_config: /usr/local/etc/dovecot-db.conf managesieve_logout_format(default): bytes=%i/%o managesieve_logout_format(pop3): bytes=%i/%o managesieve_logout_format(managesieve): bytes ( in=%i : out=%o ) lda: postmaster_address: postmaster(a)seibercom.net mail_plugins: expire sieve: /usr/local/etc/dovecot/sieve/gerard.sieve sieve_global_path: /usr/local/etc/dovecot/sieve/gerard.sieve sendmail_path: /usr/sbin/sendmail auth default: mechanisms: plain login cram-md5 digest-md5 username_chars: abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@+ username_format: %Lu passdb: driver: sql args: /usr/local/etc/dovecot-sql.conf userdb: driver: passwd args: blocking=yes userdb: driver: sql args: /usr/local/etc/dovecot-sql.conf socket: type: listen client: path: /var/run/dovecot/auth-client mode: 438 master: path: /var/run/dovecot/auth-master mode: 438 plugin: expire: Trash 7 Spam 30 expire_dict: proxy::expire dict: expire: mysql:/usr/local/etc/dovecot-dict-expire.conf -- Jerry gesbbb(a)yahoo.com DEFAULT: The hardware's, of course.

[Dovecot] Panic: file sieve-cmu.c: line 262 (part_save): assertion failed: (buf->used - 1 == part->body_size.physical_size)
by Raffael Schmid 13 Oct '09

13 Oct '09

Hi everybody We are running in the same issue as Maciej Polewczynski does in http://www.dovecot.org/list/dovecot/2008-September/033645.html Is there already a solution? I dont think so? In the TODO-File for 1.2.2 this issue is still reported: #### [...] - sieve-cmu.c crash: i_assert(buf->used - 1 == part->body_size.physical_size); [...] #### I am not able to reproduce the problem but I think it has something to do with the charset of a mail?

[Dovecot] Bad_MIME on vacation messages
by Stephen Vaughan 12 Oct '09

12 Oct '09

Hi, I know I've brought this up before (see http://www.mail-archive.com/dovecot@dovecot.org/msg20974.html) and I've since upgraded to 1.2.6, but our vacation messages are still being rejected because of Bad_MIME. We are using Dovecot Sieve 0.1.12, the auto reply message contains ^M characters at the end of a few lines, they are only visable through vi, example: Received: from mail.domain.com (HELO alejandro.domain.com) (123.123.123.123) by mail.domain.com.au with SMTP; 7 Oct 2009 17:48:13 -0600 Received: (qmail 3531 invoked from network); 8 Oct 2009 10:48:18 +1100 Received: from unknown (HELO mail.domain.com.au) (192.168.200.10) by alejandro.domain.com with SMTP; 8 Oct 2009 10:48:18 +1100 Received: (qmail 16185 invoked by uid 1007); 8 Oct 2009 10:48:17 +1100 X-Sieve: Dovecot Sieve 0.1.12^M Message-ID: <dovecot-sieve-1254959297-930199-0@max>^M Date: Thu, 08 Oct 2009 10:48:17 +1100^M From: <clair(a)max.team.domain.com> To: <admin(a)domain.com.au> Subject: Out of office reply^M Auto-Submitted: auto-replied (vacation)^M Precedence: bulk^M MIME-Version: 1.0^M Content-Type: text/plain; charset=utf-8^M Content-Transfer-Encoding: 8bit^M Is there someway to fix this?

Re: [Dovecot] mail archiving (Andreas Ntaflos)
by dhottinger＠harrisonburg.k12.va.us 11 Oct '09

11 Oct '09

Thanks Andreas, Ill look int postfix. Ive always used sendmail and was able to migrate my mailman mailing lists and aliases files over from my old mailserver several years ago when it lost its drives (thank god for backups). Luckily at that time I had a server that I was building for another totally different reason, and I just moved my configs over. Ive actually never had any issues with sendmail, but I will agree that documentation is low. Thanks for the help. As always everyone here is very helpful. take care, ddh -- Dwayne Hottinger Network Administrator Harrisonburg City Public Schools "Everything should be made as simple as possible, but not simpler." -- Albert Einstein "The hottest places in Hell are reserved for those who, in times of moral crisis, preserved their neutrality." -- Dante

[Dovecot] sievec fails when last line is a comment without trailing \n
by Peter Marschall 11 Oct '09

11 Oct '09

Hi, when switching from Dovecot 1.1 + cmusieve to Dovecot 1.2 + sieve I stumbled upon the following problem: My sieve files, generated with Dovecot 1.1's managesieve, did not compile anymore with sieve's sievec. The error message was: error: end of file before end of hash comment. Looking a bit closer I found that the last line, which was a comment, did not have a trailing newline. Adding a newline fixed the problem. I do not know if Dovecot 1.2's managesieve behaves differently, but the upgrade from cmusieve to sieve In the spirit of "be generous in what you accept but strict in what you send", is it possible for sievec to not throw an error in this case, but simply compile the file. This might help other updates from cmusieve -> sieve as well. Thanks in advance. Peter -- Peter Marschall peter(a)adpm.de

[Dovecot] soft quota lda question
by toni＠dingsbums.org 10 Oct '09

10 Oct '09

hi all, i'm using dovecot deliver (lda) and i want to show quota to the users via imap/pop3, but i don't want to enforce it (i.e. don't reject/bounce mails when quota is exceeded). protocol imap { mail_plugins = quota imap_quota } protocol pop3 { mail_plugins = quota } # In case you're using deliver: protocol lda { #mail_plugins = quota } does it work if i just comment out the "mail_plugin = quota" in the protocol lda section and leave the imap/pop3 configuration or is there another better way to do this? thanks in advance, someone2.0

[Dovecot] status & use-case of fts_solr?
by PGNet Dev 10 Oct '09

10 Oct '09

i've deployed a Solr server, and setup Dovecot for *both* squat & solr FTS. iiuc, reading at, http://wiki.dovecot.org/Plugins/FTS http://wiki.dovecot.org/Plugins/FTS/Solr as of dovecot v1.1.2, squat's required for IMAP compliance; solr search breaks it. is that still the case in v1.2? Is IMAP-compliant Solr search possible? planned? if the goal is fast, indexed FTS of dovecot IMAP stores from within a MUA, is fts_solr even helpful? or is it targeted for web interfaces to search ... ? thanks.

Re: [Dovecot] What exactly do you mean by archiving?
by dhottinger＠harrisonburg.k12.va.us 10 Oct '09

10 Oct '09

I mean every single email sent and recieved is kept for a period of time (3 -5 years) separate from users mail, and emails cant be deleted. Ideally emails would have compression, mailboxes need to be searchable easily, and some mechanism whereby attachments sent to multiple people only get saved once, and emails sent to multiple people only get saved once. I could do something with procmail that copies every email coming in to another directory easily, but that doesnt solve the sent email. Ive looked at several commercial products, but none seem to work nicely with sendmail. Thanks for the information, I'll look and see if sieve will work better for me than procmail. Im not sure thought that your method will pass the test come litigation time (if that every happens). thanks, ddh -- Dwayne Hottinger Network Administrator Harrisonburg City Public Schools "Everything should be made as simple as possible, but not simpler." -- Albert Einstein "The hottest places in Hell are reserved for those who, in times of moral crisis, preserved their neutrality." -- Dante

[Dovecot] @2.0, --sysconfdir incorrectly populated with dovecot/*.conf
by PGNet Dev 10 Oct '09

10 Oct '09

to document from #irc, in 1.2.x, specifying ./configure ... --sysconfdir=/path/to/dir ... correctly results in dovecot.conf looked for as "/path/to/dir/dovecot.conf". in 2.0, dovecot incorrectly creates a dovecot dir in the sysconfdir, and looks for, /path/to/dir/dovecot/dovecot.conf 2.0's behavior should be made consistent with the correct implementation in 1.2.x, or clarified as different in --help/docs. thanks.

[Dovecot] very frequent disconnections
by Dan Christensen 09 Oct '09

09 Oct '09

I've installed dovecot 1:1.1.11-0ubuntu4.1 on my jaunty system. Access from the same host works well, but when I access remotely (from various MUAs and networks) I get *very* frequent disconnects. Authentication is fine, and I can usually open a mail folder, but larger operations such as copying 20 messages into an imap folder always get disconnected. I can reconnect, but I often get disconnected again in a few seconds, especially if I do more than very light access. I've enabled all the logging I'm aware of, but I don't see any explanations.

[Dovecot] Binary locations
by Timo Sirainen 09 Oct '09

09 Oct '09

Where do you think the following binaries should be installed to? The possible locations are: - bin/ - sbin/ - libexec/dovecot/ (or lib/dovecot/ in most Linux distros) So the binaries are: 1) These probably belong to bin/ or sbin/ or both: - authtest - dovecotpw - doveadm 2) Binaries that you might want to call from mail_executable setting: - rawlog - gdbhelper 3) Index file dumping programs, mostly meant for debugging problems: - idxview - listview - logview - mailboxlogview - threadview 4) Some extra tools that might be useful sometimes: - imap-utf7 : Encode/decode IMAP mailbox names (mUTF-7 <-> UTF-8) - maildirlock : Lock a Maildir, primarily intended for compressing files in maildir And perhaps some of the binaries should be renamed? The authtest actually now looks like a bad name. Maybe it should have been "doveauthtest" or "dovecot-authtest" or ..?

[Dovecot] Using sieve with virtual delivery & maildir
by Jerry 09 Oct '09

09 Oct '09

I am using Postfix virtual users/domains with Dovecot virtual delivery to maildir style mailboxes. Now I want to get sieve working to sort out a few minor delivery problems. I want all mail with a message header "Delivered-To: foo+bar(a)domain.com placed in the /var/mail/vhost/example.com/foo/new directory. Would this work: require "fileinto"; if anyof (header :contains "Delivered-To" "foo+bar(a)domain.com") { fileinto "foo(a)example.com"; stop; } Running 'sieve-test' works OK; however, I do not want to implement it and suddenly start losing mail. -- Jerry gesbbb(a)yahoo.com Outside of a dog, a book is a man's best friend: and inside a dog, it's too dark to read.

[Dovecot] how to config dovecot for multiple domains, multiple SSL certs, and conditional IP access -- with passwd-file passdb?
by PGNet Dev 09 Oct '09

09 Oct '09

at them moment, i've configured dovecot for a flat passwd-file, annd static userdb. from dovecot.conf, ... auth default { mechanisms = plain digest-md5 cram-md5 user = mail ... passdb passwd-file { args = /data/mail/users/imap_user_file } userdb static { args = static uid=mail gid=mail home=/data/mail/store/Domains/%d/Accounts/%n quota=maildir:storage=4096 nice=10 } ... i'd like to configure dovecot to, host multiple domains, each on a separate IP setup a separate SSL cert for each domain respond with a different login_greeting for each domain restrict access to, and access type (e.g., TLS req'd vs noTLS, secure auth OK) of, imap login based with conditional rules based on the guest's IP address. all of these things are currently implemented on the non-dovecot imap server i'm migrating _from_, and i'd like to preserve these capabilities. can any/all of these be accomplished with a passwd-file flatfile lookup? i know i can restrict IP access in passwd-file with 'allow_nets=', but atm i'm unclear how i'd do that for multiple domains, etc. i understand that much can be accomplished with custom SQL queries, but for a small install would _prefer_ to stay flat file. i'm finding bits & pieces of capability in docs, etc -- but, so far, nothing comprehensive/all-inclusive. which makes me wonder a bit -- why not? any comments/advice would be much appreciated. thanks!

[Dovecot] Move messages marked as Spam
by michel＠casa.co.cu 08 Oct '09

08 Oct '09

Hello I have implemented recently in my work bogofilter to mark messages as Spam or Ham, currently is working perfectly, but I want to move those messages marked as spam to a folder called spam. I installed dovecot-sieve with the intention of using fileinto to accomplish this. my question is: where I put this: require "fileinto"; if header :contains "X-Bogosity" "Spam" { fileinto "Spam"; } so that all messages that come to my users go into the spam folder? and how i handle messages that are marked as "Unsure" X-Bogosity: Unsure Thanks Michel ---------------------------------------------- Webmail, servicio de correo electronico Casa de las Americas - La Habana, Cuba.

[Dovecot] Logging in with '+' delimiter
by Jerry 07 Oct '09

07 Oct '09

Dovecot v1.2.4 FreeBSD-7.2 I have Postfix configured to use Virtual Users & Domains and use Dovecot for virtual delivery. Postfix also sends, dovecot correctly places mail with '+'addressing; i.e., "foo+bar(a)domain.com" into "path-to-mail/domain.com/foo+bar". The problem is when I attempt to access the mailbox, the user name: foo+bar(a)domain.com is rejected. Is this by design, or is there a way to circumvent this problem? -- Jerry gesbbb(a)yahoo.com Fortune favors the lucky.

[Dovecot] Is it possible to authenticate against Active Direcotry using the whole e-mail?
by Δημήτριος Καραπιπέ ρης 07 Oct '09

07 Oct '09

Hi all! Is it possible to authenticate against Active Directory, using the whole e-mail address and not the user part (%n), so that if you support mutiple domains, all users should authenticate with their e-mail addresses. I use auth_bind_userdn = DOMAIN \ %u but somehow the *mail* attribute of Active/LDAP should be employed. thanks in advance Dimitrios Karapiperis

The LDAP would be for the configuration. Do you actually want the IMAP/POP3 clients to use Kerberos? For plaintext auth I don't see any benefit in Dovecot using Kerberos rather than LDAP (and it doesn't support that, except via pam_kerberos or whatever I guess). But for clients to use Kerberos (GSSAPI) and authenticate against AD while Dovecot is in the middle... I've no idea.

[Dovecot] Samba AD and Dovecot
by Trever L. Adams 07 Oct '09

07 Oct '09

Hello All, I haven't seen the answer to this, maybe I am just using the wrong searches. I have two queries related to this: 1) I have seen how to configure for LDAP and Kerberos. AD uses both together. All user information is in AD/LDAP and authentication is AD/Kerberos. How can I configure Dovecot to use both appropriately? 2) I can cause Samba to create certain directories on login, etc. However, I am needing to do this for Dovecot (and Postfix using Dovecot deliver). I would prefer to use Dovecot functionality for this, not Samba.This is not the autocreate folder/subscribe stuff, at least I think not. For example if I have a directory /var/mail/domain/user. Can I have Dovecot auto create (with proper permissions) the domain/user part? These would be used for maildir. Thank you, Trever Adams

Note to all: If you are running Dovecot on a system where any of the mailboxes are nfs v4 mounted from a RHEL (or derivative) server DO NOT upgrade that server to an unpatched 2.6.18-164 kernel, it is very broken at this time. Not only will Dovecot fail but you're likely to have a myriad of other problems. https://bugzilla.redhat.com/show_bug.cgi?id=523797 https://bugzilla.redhat.com/show_bug.cgi?id=524520 > On Mon, 2009-10-05 at 10:30 -0400, vwc72283(a)voicenet.com wrote: >> So, it is reproducible.

Hello All, I am having difficulties in running dovecot with mysql accounts. The db worked but the config file is hardly something I could do to work properly as it should be, it does even not run saying various errors found in dovecot.conf Has anyone already built dovecot server to run with with a mysql base ? Could it be so that one sends me a conf file that shall work to help me ? Thanks. Jean-François

[Dovecot] Move messages marked as Spam
by Michel Bulgado 06 Oct '09

06 Oct '09

Hello I have implemented recently in my work bogofilter utility to mark messages as Spam or Ham, currently is working perfectly, but I want to move those messages marked as spam to a folder called spam. I installed dovecot-sieve with the intention of using fileinto to accomplish this. my question is: where I put this: require "fileinto"; if header :contains "X-Bogosity" "Spam" { fileinto "Spam"; } so that all messages that come to my users go into the spam folder? and how i handle messages that are marked as "Unsure" X-Bogosity: Unsure Thanks Michel

[Dovecot] Dovecot 1.2.4 - assertion crash in view_lookup_seq_range
by Brandon Davidson 06 Oct '09

06 Oct '09

Hi all, We have a number of machines running Dovecot 1.2.4 that have been assert crashing occasionally. It looks like it's occurring when the users expunge their mailboxes, but I'm not sure as I can't reproduce it myself. The error in the logs is: Oct 6 07:33:09 oh-popmap3p dovecot: imap: user=<YYYY>, rip=XXXX, pid=11931: Panic: file mail-index-view.c: line 264 (view_lookup_seq_range): assertion failed: (first_uid > 0) Oct 6 07:33:09 oh-popmap3p dovecot: imap: user=<YYYY>, rip=XXXX, pid=11931: Raw backtrace: imap [0x49e130] -> imap [0x49e193] -> imap [0x49d816] -> imap [0x47e462] -> imap(mail_index_lookup_seq+0x12) [0x47e022] -> imap(mail_index_view_sync_begin+0x36a) [0x47ffba] -> imap(index_mailbox_sync_init+0x7f) [0x45e56f] -> imap(maildir_storage_sync_init+0x100) [0x43cb70] -> imap(imap_sync_init+0x67) [0x428177] -> imap(cmd_sync_delayed+0x174) [0x4283c4] -> imap(client_handle_input+0x19e) [0x420a0e] -> imap(client_input+0x5f) [0x4213ff] -> imap(io_loop_handler_run+0xf8) [0x4a5e98] -> imap(io_loop_run+0x1d) [0x4a4fad] -> imap(main+0x620) [0x428cc0] -> /lib64/libc.so.6(__libc_start_main+0xf4) [0x323dc1d994] -> imap [0x4199f9] Oct 6 07:33:09 oh-popmap3p dovecot: dovecot: child 11931 (imap) killed with signal 6 (core dumped) GDB stack information and some additional details are available here: http://uoregon.edu/~brandond/dovecot-1.2.4/stack.txt We are planning to go to 1.2.6 sometime in the next week or two, but I thought I'd try to track this particular error down just in case it's still an issue after the upgrade. -Brad

[Dovecot] dovecot 1.2.5 - can't create auth listener
by dovecot＠nro.ca 06 Oct '09

06 Oct '09

Hi. I have version 1.1.11 working fine with multiple servers. When I upgrade to 1.2.4 or 1.2.5 I keep getting an error 'can't create auth listener' (address in use) I have two ip addresses (lets call them 1.0.0.1 and 1.0.0.2). Each ip address has it's own certificate and set of servers with custom ports. I don't know how the configuration is supposed to work and it was a lot of google and trial and error to get it working. My configuration file is pretty basic so maybe someone can point out where I'm going wrong. I stripped out the few comments and unrelated settings. #listen = * disable_plaintext_auth = no ssl_ca_file = myca.crt protocol lda { postmaster_address = postmaster(a)example.com } server a1 { protocols = pop3 ssl_cert_file = a1.crt ssl_key_file = a1.key listen = 1.0.0.2:110 1.0.0.2:111 auth default { mechanisms = plain passdb pam { } userdb passwd { }}} server a2 { protocols = pop3s ssl_cert_file = a1.crt ssl_key_file = a1.key listen = 1.0.0.2:995 auth default { mechanisms = plain passdb pam { } userdb passwd { }}} server n1 { protocols = pop3 ssl_cert_file = n1.crt ssl_key_file = n1.key listen = 127.0.0.1:110 127.0.0.1:111 1.0.0.1:110 1.0.0.1:111 auth default { mechanisms = plain passdb pam { } userdb passwd { }}} server n2 { protocols = pop3s ssl_cert_file = n1.crt ssl_key_file = n1.key listen = 127.0.0.1:995 1.0.0.1:995 auth default { mechanisms = plain passdb pam { } userdb passwd { }}} ...and repeat for imap, imaps Thanks, Sean

[Dovecot] Debugging IMAP ACLs
by Kerem Erciyes 06 Oct '09

06 Oct '09

Hello, I upgraded my server to 1.2.4 and now I'm trying to implement ACL support to use with Bynari Insight Connector. Starting out with the wiki page on shared namespaces from http://wiki.dovecot.org/SharedMailboxes/Shared I tried to implement shared mailbox support so that my customers can enjoy more exhange-like qualities with outlook. However I am not sure if the ACLs or Shared Namespaces are really working. I sure would like some help debugging ACL requests by clients, and the configuration I did.

[Dovecot] issues with ACL and Public Namespaces
by Anton Dollmaier 06 Oct '09

06 Oct '09

Hi all, after configuring dovecot to serve private and Public Namespaces per domain with ACLs per shared folder, everything worked great: In every shared folder I created a "dovecot-acl"-file with the permissions of every user: > user=user5(a)example.com > user=user6(a)example.com lrwstiea The subscriptions are handled with "subscriptions=no", so every local User can subscribe to shared folders as he likes. As the shared folders are managed via webinterface, the cronjob creating and deleting the folders also changes the subscriptions of every user, adding or removing the public folders as permissions are granted. RoundCube Webmail, Thunderbird and Outlook have no problems accessing and using the public folders, but a customer has problems with his Mac: In Apple Mail the folders are not visible, even when subscriptions are previously set in another mailclient. In RoundCube, I spottet another issue: subscribed public folders are usable in the "Mail"-area, but no public folder is listed in the "Folder"-settings - not even the already subscribed ones. Setting "list=yes" to the public namespace, RC lists only the prefix "shared" as a folder, but no subfolders - "list=children" shows no folder at all. As I checked the rawlog and debug-infos with "mail_debug=yes", I saw the possible cause for my problems: When checking the Folder Subscriptions in RoundCube, Dovecot tries to find an ACL file for the public folders, but does not check the public folders, but in the private Maildir: > Oct 6 15:24:16 ipx02 dovecot: IMAP(user6(a)example.com): Loading modules from directory:

[Dovecot] v1.2.6 released
by Timo Sirainen 06 Oct '09

06 Oct '09

http://dovecot.org/releases/1.2/dovecot-1.2.6.tar.gz http://dovecot.org/releases/1.2/dovecot-1.2.6.tar.gz.sig A couple of random things: - I decided to start using "hg sign" to gpg sign all releases in mercurial repository. - v2.0.alpha1 will hopefully be released in a week or two. Changes since 1.2.5: * Upgraded to Unicode 5.2.0 + Added authtest utility for doing passdb and userdb lookups. + login: ssl_security string now also shows the used compression. - quota: Don't crash with non-Maildir++ quota backend. - imap proxy: Fixed crashing with some specific password characters. - dovecot --exec-mail was broken. - Avoid assert-crashing when two processes try to create index at the same time.

[Dovecot] Proxy setup & upgrade from 1.0.3 to 1.1.7
by Adrian Wojcicki | Unternehmensberatung Wojcicki 06 Oct '09

06 Oct '09

Hi guys! I hope somebody can help me with my problem: We have a server running dovecot and proxying IMAPS connections to our internal network. This worked so far very good until we upgraded the server to a new SUSE Linux version and with it dovecot from version 1.0.3 to 1.1.7. My guess is that something changed in the way dovecot reads the user file as the configuration stayed the same: dovecot.conf: base_dir = /var/run/dovecot/ protocols = imaps disable_plaintext_auth = yes ssl_cert_file = /<pathtocertificate> ssl_key_file = /<pathtocertificate> ssl_disable = no ssl_listen = 80.149.64.98:993 log_path = /var/log/dovecot.log login_dir = /var/run/dovecot/login login_process_per_connection = yes login_processes_count = 3 login_greeting = main.xbdx.de IMAP What can we do for you? imap_client_workarounds = tb-extra-mailbox-sep mail_debug = no auth_debug = yes auth_cache_size = 4096 auth_cache_ttl = 7200 auth_worker_max_count = 30 auth default { userdb static { args = uid=5000 gid=5000 } passdb { driver = passwd-file args = /etc/dovecot/dovecot.passdb } socket listen { client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } mechanisms = plain login user = root count = 1 } dovecot.passdb: testuser1:::::::host=<internalip> port=143 nodelay=y nologin=y proxy=y testuser2:::::::host=<internalip> port=143 nodelay=y nologin=y proxy=y dovecot.log: dovecot: Oct 06 10:37:26 Info: Dovecot v1.1.7 starting up dovecot: Oct 06 10:37:26 Info: auth(default): passwd-file /etc/dovecot/dovecot.passdb: Read 2 users dovecot: Oct 06 10:37:27 Info: auth(default): new auth connection: pid=8135 dovecot: Oct 06 10:37:27 Info: auth(default): new auth connection: pid=8136 dovecot: Oct 06 10:37:27 Info: auth(default): new auth connection: pid=8137 dovecot: Oct 06 10:37:39 Info: auth(default): new auth connection: pid=8139 dovecot: Oct 06 10:37:39 Info: auth(default): client in: AUTH 1 PLAIN service=imap secured lip=80.149.64.98 rip=217.91.33.32 lport=993 rport=61752 resp=<hidden> dovecot: Oct 06 10:37:39 Info: auth(default): cache(adrian.wojcicki,217.91.33.32): miss dovecot: Oct 06 10:37:39 Info: auth(default): passwd-file(testuser1,217.91.33.32): lookup: user=testuser1 file=/etc/dovecot/dovecot.passdb dovecot: Oct 06 10:37:39 Info: auth(default): passwd-file(testuser1,217.91.33.32): Password mismatch dovecot: Oct 06 10:37:41 Info: auth(default): client out: FAIL 1 user=testuser1 host=<internalip> port=143 nologin proxy pass=<hidden> dovecot: Oct 06 10:37:41 Info: imap-login: Aborted login (auth failed, 1 attempts): user=<testuser1>, method=PLAIN, rip=217.91.33.32, lip=80.149.64.98, TLS Thanks!

[Dovecot] dovecot 1.0.15 upgrading to dovecot 1.1.x or 1.2.x, and POP3 UIDL issue
by Ariel Biener 05 Oct '09

05 Oct '09

Hi, We're upgrading a cluster of servers from v1.0.15 to v1.1.x or v1.2.x. It appears that the UIDL generation mechanism has changed, and thus we'll be getting POP3 dups with users that leave mail on server (which is a nasty practice, I know). From checking the sources, and performing a number of controlled tests in various scenarios, here is the outcome: upgrade from 1.0.15 to 1.1.x (latest), UIDLs change (no change to the mail backend, that is, mbox) However, the interesting part is that if for example I read a mailbox for the first time with the 1.1.x version, and then I migrate the mailbox to a different server, running 1.1.x or 1.2.x, with Maildir or mailbox the UIDL does *NOT* change. We do not have X-UIDL headers in the mailboxes. I did every possible permutation of these tests. It appears that the way UIDLs are created in 1.0.x is different than what is used in 1.1.x and 1.2.x. (I am not talking about the format, we're using the same format in both, that is, UW compatible). Since we're a largish site (university), and we have some >60k accounts, even the smallest percentage of users who use POP3 and "leave mail on server" is a large number of angry staff members landing on our helpdesk, which is the reason why we're not migrating. Has anyone ever ported the UIDL generation algorithm from 1.0.x to 1.1.x/1.2.x to maintain compatibility ? Is there some other option that I am missing ? --Ariel

[Dovecot] Quota exceeded delivery message
by michel＠casa.co.cu 05 Oct '09

05 Oct '09

Hi I have assigned quotas to my users and in turn use quota_warning for my users send them a message saying that the level of its quota is about to be exceeded. when the quota is exceeded, the script runs again sending a message to the user and is rejected by the server. there is any way to get the message when the postmaster, is delivered to the mailbox even when exceeded the quota or simply not send it once exceeded the quota level? quota_warning = storage=95%% /usr/local/bin/quota-warning.sh 95 quota = maildir quota_rule = *:storage=40M Another question: I've implemented recently in my work Bogofilter to mark messages as SPAM or HAM. Using dovecot as IMAP and POP3 server and deliver, there is some way to move messages marked as SPAM to a folder called spam or junk? I've heard that can be done with sieve, is this true? fileinto?

Postfix+MailScanner+ClamAV+Docvecot+MySql+postfix.admin... just to mention the major things. The system is CentOS 5.3 on VMware. The maildir is on an NFS share, index and control is local. About a month ago I thought I upgraded from 1.1.x to 1.2.x. by doing an rpmbuild and deploying. I say thought because today I determined the binaries were still 1.1x. Today a reboot was done after a kernel upgrade (2.6.18-128.x -> 2.6.18-164). The mail system never came back up. My assumption is that the working binaries were in memory but the images on disk were changed. Anyway, the problem is with deliver writing to the mail dir. The error is: Oct 3 21:33:58 myserver dovecot: auth(default): master in: USER 1 myaccount(a)mydomain.net service=deliver Oct 3 21:33:58 myserver dovecot: auth(default): prefetch(myaccount(a)mydomain.net): passdb didn't return userdb entries, trying the next userdb Oct 3 21:33:58 myserver dovecot: auth-worker(default): sql(myaccount(a)mydomain.net): SELECT '/home/vmail/mydomain.net/myaccount' as home, 'maildir:/home/vmail/mydomain.net/myaccount:INDEX=/var/indexes/mydomain.net/…' as mail, 5000 AS uid, 5000 AS gid, concat('dirsize:storage=', quota) AS quota FROM mailbox WHERE username = 'myaccount(a)mydomain.net' AND active = '1' Oct 3 21:33:58 myserver dovecot: auth(default): master out: USER 1 myaccount(a)mydomain.net home=/home/vmail/mydomain.net/myaccount mail=maildir:/home/vmail/mydomain.net/myaccount:INDEX=/var/indexes/mydomain… uid=5000 gid=5000 quota=dirsize:storage=0 Oct 3 21:33:58 myserver dovecot: deliver(myaccount(a)mydomain.net): auth input: home=/home/vmail/mydomain.net/myaccount Oct 3 21:33:58 myserver dovecot: deliver(myaccount(a)mydomain.net): auth input: mail=maildir:/home/vmail/mydomain.net/myaccount:INDEX=/var/indexes/mydomain… Oct 3 21:33:58 myserver dovecot: deliver(myaccount(a)mydomain.net): auth input: uid=5000 Oct 3 21:33:58 myserver dovecot: deliver(myaccount(a)mydomain.net): auth input: gid=5000 Oct 3 21:33:58 myserver dovecot: deliver(myaccount(a)mydomain.net): auth input: quota=dirsize:storage=0 Oct 3 21:33:58 myserver dovecot: deliver(myaccount(a)mydomain.net): maildir: data=/home/vmail/mydomain.net/myaccount:INDEX=/var/indexes/mydomain.net/mya… Oct 3 21:33:58 myserver dovecot: deliver(myaccount(a)mydomain.net): maildir++: root=/home/vmail/mydomain.net/myaccount, index=/var/indexes/mydomain.net/myaccount, control=/var/indexes/mydomain.net/myaccount, inbox=/home/vmail/mydomain.net/myaccount Oct 3 21:33:58 myserver dovecot: deliver(myaccount(a)mydomain.net): Namespace : Using permissions from /home/vmail/mydomain.net/myaccount: mode=0770 gid=-1 Oct 3 21:33:58 myserver dovecot: deliver(myaccount(a)mydomain.net): open(/home/vmail/mydomain.net/myaccount/tmp/1254620038.M241510P27678.myserv… failed: Permission denied Oct 3 21:33:58 myserver dovecot: deliver(myaccount(a)mydomain.net): msgid=<200910040116.n941GjtJ001913(a)nm2srvp01.mydomain.net>: save failed to INBOX: Internal error occurred.

[Dovecot] Expire Plugin Configuration Question
by Roland Roberts 05 Oct '09

05 Oct '09

I am very confused looking at the expires plugin and its configuration. What is confusing me the most is that it appears that I have to configure expiration globally, meaning, for example, that the Trash mailbox expiration interval is the same regardless of the user. What I really am looking for is per-user configurable rules. Those would obviously not be able to be in a file configuration but would have to be in some shared/sharable resource. Is such a thing possible? What I really want is the ability to move my expiration rules out of my email client and into dovecot. That would be very useful for me since I access my mail from more than one host and via more than one client. roland -- PGP Key ID: 66 BC 3B CD Roland B.

[Dovecot] v1.1.19 released
by Timo Sirainen 04 Oct '09

04 Oct '09

http://dovecot.org/releases/1.1/dovecot-1.1.19.tar.gz http://dovecot.org/releases/1.1/dovecot-1.1.19.tar.gz.sig This is hopefully the last v1.1.x release. - file_set_size() was broken with OSes that didn't support posix_fallocate() (almost everyone except Linux), causing all kinds of index file errors. - ldap: Fixed hang when >128 requests were sent at once. - Fixed a crash in saving messages where message contained a CR character that wasn't followed by LF (and the CR happened to be the last character in an internal buffer). - deliver: Don't send rejects to any messages that have Auto-Submitted header. This avoids emails loops. - Message decoding fixes (mainly for IMAP SEARCH, Sieve).

[Dovecot] v1.2.5 released
by Timo Sirainen 04 Oct '09

04 Oct '09

http://dovecot.org/releases/1.2/dovecot-1.2.5.tar.gz http://dovecot.org/releases/1.2/dovecot-1.2.5.tar.gz.sig I'll be more or less gone for next two weeks. Tomorrow I'm heading to MacSysAdmin in Sweden to give a Dovecot talk, the next week I'll be in Finland on vacation. After that I'm hoping to get v2.0.alpha1 released in October. * Authentication: DIGEST-MD5 and RPA mechanisms no longer require user's login realm to be listed in auth_realms. It only made configuration more difficult without really providing extra security. * zlib plugin: Don't allow clients to save compressed data directly. This prevents users from exploiting (most of the) potential security holes in zlib/bzlib. + Added pop3_save_uidl setting. + dict quota: When updating quota and user isn't already in dict, recalculate and save the quota. - file_set_size() was broken with OSes that didn't support posix_fallocate() (almost everyone except Linux), causing all kinds of index file errors. - v1.2.4 index file handling could have caused an assert-crash - IMAP: Fixes to QRESYNC extension. - virtual plugin: Crashfix - deliver: Don't send rejects to any messages that have Auto-Submitted header. This avoids emails loops. - Maildir: Performance fixes, especially with maildir_very_dirty_syncs. - Maildir++ quota: Limits weren't read early enough from maildirsize file (when quota limits not enforced by Dovecot) - Message decoding fixes (mainly for IMAP SEARCH, Sieve).

[Dovecot] Configuring for virtual users in Postfix
by Jerry 03 Oct '09

03 Oct '09

FreeBSD-7.2 with Postfix-2.7x OK, this is my first attempt to configure Dovecot using Postfix and virtual users. In the LDA.Postfix.txt file, there is a reference to making the following setting: dovecot_destination_recipient_limit = 1 virtual_mailbox_domains = your.domain.here virtual_transport = dovecot However, Postfix does not recognize the dovecot_destination_recipient_limit = 1 setting. There is a "virtual_destination_recipient_limit =" setting in Postfix. Is that the setting that I should tweak? -- Jerry gesbbb(a)yahoo.com There is no TRUTH. There is no REALITY. There is no CONSISTENCY. There are no ABSOLUTE STATEMENTS. I'm very probably wrong.

[Dovecot] Mailbox locking problem with iphone and POP3
by Bill Dunn - VCI Internet Services 03 Oct '09

03 Oct '09

I have a problem I can't seem to fix. I have dovecot configured to do POP3 with plain text authentication using a MySQL database. I am using Dovecot 1.0.7 with fcntl locking. My problem has been when an iPhone/iPod checks email. The iPhone/iPod doesn't disconnect with a TCP FIN packet and it leaves the mailbox in a locked state and prevents the user's desktop from checking email. I have tried changing the file locking method and other config file options without any luck. Oddly, I am using the last version of cucipop on another server with fcntl and lockf file locking and it doesn't have this problem. If someone could clue me in I'd be very grateful. Bill

[Dovecot] Folder Management Dovecot >1.2
by Carlos Candeias 02 Oct '09

02 Oct '09

Regardless of the mail client no user can modify, move, delete or subscribe an imap folder with Dovecot >1.2.1 (meanwhile 1.2.5). Dovecot apparently have some dotlock problems: (From dovecot.log) Oct 02 14:58:19 IMAP(jcci): Error: fchown(/candeias/home/jcci/.mail/Maildir/subscriptions.lock, -1, 0(root)) failed: Operation not permitted (egid=1003(management), group based on /candeias/home/jcci/.mail/Maildir) Oct 02 14:58:19 IMAP(jcci): Error: file_dotlock_open() failed with subscription file /candeias/home/jcci/.mail/Maildir/subscriptions: Operation not permitted Oct 02 14:58:20 IMAP(jcci): Error: fchown(/candeias/home/jcci/.mail/Maildir/subscriptions.lock, -1, 0(root)) failed: Operation not permitted (egid=1003(management), group based on /candeias/home/jcci/.mail/Maildir) Oct 02 14:58:20 IMAP(jcci): Error: file_dotlock_open() failed with subscription file /candeias/home/jcci/.mail/Maildir/subscriptions: Operation not permitted Oct 02 14:58:20 IMAP(jcci): Error: fchown(/candeias/home/jcci/.mail/Maildir/subscriptions.lock, -1, 0(root)) failed: Operation not permitted (egid=1003(management), group based on /candeias/home/jcci/.mail/Maildir) Oct 02 14:58:20 IMAP(jcci): Error: file_dotlock_open() failed with subscription file /candeias/home/jcci/.mail/Maildir/subscriptions: Operation not permitted Oct 02 14:58:21 IMAP(jcci): Error: fchown(/candeias/home/jcci/.mail/Maildir/subscriptions.lock, -1, 0(root)) failed: Operation not permitted (egid=1003(management), group based on /candeias/home/jcci/.mail/Maildir) Oct 02 14:58:21 IMAP(jcci): Error: file_dotlock_open() failed with subscription file /candeias/home/jcci/.mail/Maildir/subscriptions: Operation not permitted Oct 02 14:58:21 IMAP(jcci): Error: fchown(/candeias/home/jcci/.mail/Maildir/subscriptions.lock, -1, 0(root)) failed: Operation not permitted (egid=1003(management), group based on /candeias/home/jcci/.mail/Maildir) Oct 02 14:58:21 IMAP(jcci): Error: file_dotlock_open() failed with subscription file /candeias/home/jcci/.mail/Maildir/subscriptions: Operation not permitted This was an attemt of changing a subscription. Another weird point: I can create an IMAP folder although it does not show up in the folder list. But the new folder is in the subscription list, just marked as unsubscribed and there is no way to change that. This problem is safely reproducible and I wonder whether I should be really the only person having this trouble. I'm using MAILDIR and simple plain test authentification (internal mail server). The location is mail_location: maildir:~/.mail/Maildir which means a subfolder in each user's home directory. All homes are exported to NFS, but the Dovecot is just on the same server and thus accesses locally. Downgrade to version 1.1.17 solves all problems. Archlinux x86_64, Linux 2.6.30 It would be really great if somebody could understand the cause and suggest a solution!

[Dovecot] Problem with LSUB and public namespace
by Julien Danjou 02 Oct '09

02 Oct '09

Hi, I'd like to know if the following is normal. I've a setup with 2 namespace (private/public) where each user can use subscriptions. This problem is triggered by claws-mail, which uses LSUB to get subscribed mailboxes: * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE AUTH=PLAIN] Dovecot ready. . login user password . namespace * NAMESPACE (("INBOX." ".")) NIL (("public." ".")) . OK Namespace completed. . subscribe public.Admin . OK Subscribe completed. . LSUB "" "%" * LSUB () "." "INBOX" . OK Lsub completed. LSUB does not return "public" as namespace :-( Is this a bug in dovecot, a bug in Claws mail, or a misconfiguration of my dovecot server? I can provide more info if needed. Cheers, -- Julien Danjou // ᐰ <julien(a)danjou.info> http://julien.danjou.info // 9A0D 5FD9 EB42 22F6 8974 C95C A462 B51E C2FE E5CD // There is nothing under this line.

[Dovecot] Disconnected: Too many invalid IMAP commands
by Gabriele 02 Oct '09

02 Oct '09

Greetings, I'm having big issues here, hope you can help me… Ubuntu Server 8.04, postfix 2.5.1, dovecot 1.0.10, postfixadmin (MySQL+ virtual users)… I am trying to move e-mails from an old IMAP account to my new dovecot IMAP server accounts. The old server is EIMS (Eudora Internet Mail Server, so a sort of mbox format)… I move messages by drag 'n' dropping in Mozilla Thunderbird. No problems with messages under 4MB size (there are huge messages, up to 25MB), but as soon as I try to move messages from 4MB and up, the connection hangs, nothing happens, the application becomes barely responsive, I have quit and re-open it to make it behave properly. In the logs, I read (user and IPs are fake, here): Sep 18 07:52:06 in dovecot: imap-login: Login: user=<user@my-domain>, method=PLAIN, rip=123.123.123.123, lip=123.123.123.123 Sep 18 07:52:06 in dovecot: IMAP(user@my-domain): Disconnected: Too many invalid IMAP commands. Could it be a client (Thunderbird) issue? I have tried with Apple Mail 4.1, same problem, same logs. Could it be a quota limit (googling around, I read that sometimes the error may be triggered by dovecot when exceeding the quota limit) Accout usage is actually at 1%… Could drag 'n' drop be the wrong way to have things done? I have also downloaded the huge e-mails from EIMS to Thunderbird Local Folders, the problem arises when I try to upload, so the culprit seems to be the new "system". I really need help at this point… any hints? Thanks in advance for any help you will offer. Gabriele

[Dovecot] Password and special caracter

02 Oct '09

Problem : I have a problem with special character in the password. Character like ! * é are deleted My configuration : - a smtp server with Postfix 2.6 and Dovcot 1.1.11. - a windows 2003 server with active directory for accounts and boxes I use SMTP / SASL on my postfix 2.6 to authenticate my remote laptop users (allow legitimate users to relay mail). To do that, I use SASL Dovecot fonctionnality and ldap request to verify login/password who are declared on a server in Windows 2003 (Active Directory). It works fine with simple password but not with complex password. I have a problem with special character in the password. Character like ! * é are deleted before comparaison. Any idea ? Regards

Dear my friends.... I use OpenSuSE 11.1, KMail and DoveCot version: " sussy:/etc/ssl/certs # dovecot --version 1.1.7 ". This is the configuration of my DoveCot: " sussy:/etc/ssl/certs # dovecot -n # 1.1.7: /etc/dovecot/dovecot.conf # OS: Linux 2.6.27.29-0.1-default i686 openSUSE 11.1 (i586) base_dir: /var/run/dovecot/ log_path: /var/log/dovecot.log protocols: imap imaps pop3 listen(default): * listen(imap): * listen(pop3): *:110 ssl_disable: yes disable_plaintext_auth: no login_dir: /var/run/dovecot//login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login login_greeting: Dovecot of MyGoogle.Com ready. mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 auth default: debug_passwords: yes passdb: driver: pam userdb: driver: passwd ". I have created local linux user account on my Postfix+DoveCot server. I also can access the content of my mailbox from my KMail. I am so happy but once I try to send email (testing the smtp) than I realize that I can't send an email from my email client (KMail). I use this setting on my email client: 1. 'incoming mailserver' == 'outgoing mailserver' == 'mail.mygoogle.com' (pseudonome). Also username and password are all the same between incoming/outgoing mailserver, namely the local userlogin of LINUX. As the username, I put 'ricky' (but not 'ricky(a)mygoogle.com'). 2. smtp authentication: No encryption and plaintext. The error message on my KMail is: " Sending failed: Your SMTP server does not support The server responded: "5.7.8 Error: authentication failed: generic failure". Choose a different authentication method. The server responded: "5.7.8 Error: authentication failed: generic failure" The message will stay in the 'outbox' folder until you either fix the problem (e.g. a broken address) or remove the message from the 'outbox' folder. The following transport was used: mygoogle.com Do you want me to continue sending the remaining messages? " and also: " Sending failed: Your SMTP server does not support The server responded: "5.7.8 Error: authentication failed: generic failure". Choose a different authentication method.

[Dovecot] Encryption Plugin
by Patrick McLean 01 Oct '09

01 Oct '09

Hi, There was a discussion a few months ago about a plugin for encrypting email before it hit the disk on the server, and doing transparent decryption while serving data to the client, see: http://www.dovecot.org/list/dovecot/2009-July/041262.html We have a client/user who is interested in such a plugin, and I was wondering if there has been any progress on it yet. In our particular case, server-side on-the-fly decryption would be acceptable. This service is useful in the case of a somewhat paranoid user who does not want the IT staff to have direct access to their email, without going through some major hoops (http://hushmail.com actually offers both server and client side decryption for these reasons). The way I would imagine the plugin working is public-key encryption being done on the message as it was being delivered (plug in to dovecot's deliver). Then when a client connects, the private key is decrypted with the user's password and used to decrypt the messages on the fly. Depending on performance, it may be an idea to convert messages to use symmetric with rotating keys encrypted with the public key encryption. If this were going to be done, I would think an IMAP protocol extension may be an idea so client-side encryption would be an option as well, so there would be end-to-end security.

[Dovecot] OT: IMAP folder aliases
by Patrick Ben Koetter 01 Oct '09

01 Oct '09

It seems that there is no standard for folder names that deal with typical message classes such as drafts, outbox, sent, spam etc. At least there's no common sense on a naming convention that tells how client should handle this. Worse than this, most IMAP clients auto-create folders according to their own naming convention if they don't exist. Every client introduces its own view. Users OTOH expect a single view that makes it easy for them to find their messages. They are unwilling to search in "sent", "sent-mail" or "Sent items" for "messages that have been sent". I doubt that software producers will adopt a standard naming convention if it was introduced within a useful time span. Has anyone seen an approach or a solution that solves the problem from a users point of view? A server side alias list that maps to a server standard? p@rick -- state of mind Digitale Kommunikation http://www.state-of-mind.de Franziskanerstraße 15 Telefon +49 89 3090 4664 81669 München Telefax +49 89 3090 4666 Amtsgericht München Partnerschaftsregister PR 563

Fair enough. But I never saved the tail when the problem occured. I can now extract this again from the info log (getting everything between 11:06 to 11:08 which should be within the problem time...). Who should I send it to? It's 181 lines to 'privatize' and I'd prefere not to send a unprivatized file to the list...

This may be enough for Timo, but its always better to give the full logs of one of these transactions - not just the dovecot error log, but full system logs, showing the message entering the system, each step of processing, and ending with the final delivery (attempt)... -- Best regards, Charles Marcus I.T.

[Dovecot] Compile dovecot 1.2.5 with managesieve patch 0.11.9?
by Seba 01 Oct '09

01 Oct '09

Hi, is it possible to compile dovecot 1.2.5 with the managesieve patch 0.11.9 which is for dovecot 1.2.4 or is it better to wait if a new managesieve patch is released? Maybe 1.2.5 will work too? Thanks, Seba
