[Dovecot] iphone connection problem
by dovecot＠feb17.org 17 Sep '08

17 Sep '08

Hi, I recently changed from uw imap to dovecot on the sound recommendation of a friend and have mostly succeeded in getting all of my clients up and running, but am really stuck with the iPhone which is failing to make connections. I run certificates on all of my clients and thunderbird happily connects both locally and remotely. I installed the certificate on the iPhone after great pain (pk12 via the Web administration utility). When you open the configurations on the phone , it tries to make a test connection to the server and fails with a generic SSL error. Dovecot reports just a generic disconnected error (imap-login/client.c line 333), and it appears to be dropping the connection. Sep 2 09:38:17 inchoate dovecot: imap-login: Disconnected (auth failed, 0 attempts): rip=209.204.139.116, lip=192.168.0.252, TLS I have run ssldump and here is the relevant section.

[Dovecot] Moving from cyrus to dovecot (a story)
by Steinar Bang 16 Sep '08

16 Sep '08

The transition was quick, and also (so far) seemingly painless. The server is an old Pentium II 233 machine that sits between my home LAN and the internet, and have sitting there, and running night and day since 1999. For the first two years it was running SuSE linux, but since 2001 it has been running debian and been continously upgraded. It was originally installed with potato, but have been apt-get dist-upgrade'd to woody, and then to sarge, and then etch, which is what it's currently running I've been using cyrus imapd since 1999 (compiled by hand on SuSE and using the debian packaged version on debian). But in all these years I've never become really friendly with it. In the years leading up to 1999 I had been running UoW imapd at work, and I wasn't too impressed with it at that point in time. The alternative choices were courier and cyrus, and I picked cyrus more or less arbitrarily. By "never become really friendly", I mean - I've never really gotten a good understanding of the configuration - I've never quite understood what the documentation have said about authentication and SSL support. I've gotten things to work by trial and error - Four times the seen data bases have become corrupt. Two times during upgrades (one of them after I had switched to skip lists), and two times on their own, while I was still running BDB - Since delivery was to a central spool and database, owned by user cyrus, has meant that I had to use sieve (which is another thing I've never quite understood) for mail filtering, instead of dear old procmail Cyrus has lots of stuff related to scaling and having mailboxes for users that have no users on the host, but that's not really relevant to my home server. Around six months ago I stumbled over dovecot, which from my POV have the following crucial features: 1. folders under the users' home directories, either as mbox or as maildir, which allows me to do list filtering with procmail, and no central databases that can become corrupt 2. understandable configuration (the only change I'd had to do in the debian dovecot, is to allow for cram-md5 authentication) I decided om maildir as the folder format. I like the simplicity of mbox folders, but I have some archive folders with around 20k of articles each, and maildir would scale a bit better for them. Also mail delivery without locking is a very nice feature. Here's how I proceeded: - I set up dovecot on my daughter's Ubuntu Hardy machine - I ran imapsync on this machine to extract everything I had on the cyrus server to Maildir folders in the users' home directories on the Ubuntu box - I shut down fetchmail on my gateway box (since ISP port filtering and blacklisting of dynamic addresses stops direct SMTP delivery I have to use ISP gateways and mail drops) - I changed the exim conf on my gateway from using cyrdeliver to delivering to a maildir folder in the users' home directory - I restored my old .procmailrc file from subversion (my home directory is checked into subversion, this was originally a CVS repo that went subversion a couple of years ago), merged in the last version of the .procmailrc that used cyrdeliver (I gave up on that because the .procmailrc file had to be owned by user cyrus, which was very impractical), and changed the filtering rules to deliver to maildir folders - I tested some delivery - I apt-get install'd dovecot from the etch back ports pointed to from the dovecot install page http://wiki.dovecot.org/PrebuiltBinaries#head-477d52d96fcf34ad3033b13e5e5a2… This uninstalled cyrus22-imapd, but not the rest of cyrus 2.2, which blocked dovecot from starting after the install - I stopped cyrus22 and uninstalled all of the cyrus22 packages - I rsync'd the maildir folders from the Ubuntu box to the old mail server - I started dovecot - I use Gnus as my MUA. I had removed all nnimap groups related to the home server in Gnus, and resubscribed them. All folders came up in the state I had left them. Gnus stores article state on the server as custom marks, and imapsync had preserved the custom flags. I unsubscribed the groups to avoid article caching confusion, because imapsync changes the UIDs. However, all folders except INBOX had changed their names, so that didn't matter much - I started fetchmail and sent som test emails, and observed that they ended up in the right Maildir folders, and that dovecot picked them up as expected And today I accessed the server from work. So it looks like I'm back in business. This time with a server I understand a lot better. Thanx for writing it, Timo! - Steinar

I'm seeing a lot of these messages in my log files... deliver(...): Aug 10 15:18:34 Error: sieve_execute_bytecode(.../.dovecot.sievec) failed I'm guessing the file needs to be updated/recreated, but what's the "correct" way to do it? should I just remove the existing one and let the server recreate it? Thanks, david

[Dovecot] Authentication fails

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Been running dovecot 1.1.2 for about a month now. I Have strange issue that I have not been able to trouble shoot.

[Dovecot] IMAP traffic logging
by fp＠onwebworx.net 16 Sep '08

16 Sep '08

Hi! Is there any known way I can log traffic caused by IMAP sessions? First it is adequate to have a rough overall statistic let's say traffic per hour - this is easily done with iptables. But on the long term I also need information on account basis. I thought of rawlogging every IMAP session and then simply count the filesizes. But the created logs have dropouts because dovecot doesn't log whole FETCH commands what is a problem. Thanks for every idea you have! Paul

[Dovecot] Dovecot cannot unlink non-empty directory

Hi, Currently I use dovecot 1.1.3 on Debian Testing. CPU arch is x86. Mail is stored on ext3 fs. I'm having a following problem with deleting folders (there is no problem with creation of folders): Error: IMAP(test(a)laptop.aonet.pl): unlink_directory(/home/vpopmail/domains/laptop.aonet.pl/test/.//Maildir/..DOVECOT-TRASHED) failed: Permission denied HOW TO REPRODUCE 1. Create a fresh new account 2. Login to a new account and create folder say 'TestFolder' 3. When I try to delete TestFolder - it is deleted and ..DOVECOT-TRASHED appears in user's Maildir AND Error: IMAP(test(a)laptop.aonet.pl): unlink_directory(/home/vpopmail/domains/laptop.aonet.pl/test/.//Maildir/..DOVECOT-TRASHED) failed: Permission denied message appears - it is triggered from line 815 of dovecot-1.1.3/src/lib-storage/index/maildir/maildir-storage.c 4. Create 'TestFolder2' 5. Trying to delete 'TestFolder2' gives the same error: Error: IMAP(test(a)laptop.aonet.pl): unlink_directory(/home/vpopmail/domains/laptop.aonet.pl/test/.//Maildir/..DOVECOT-TRASHED) failed: Permission denied this one however, is triggered from line 806 of dovecot-1.1.3/src/lib-storage/index/maildir/maildir-storage.c 6. The folder 'TestFolder2' is not deleted and from this point no other newly created folders can be deleted too. --------------------------------------------------------- I. Yes, the file permissions are fine - all are writeable to (mail_uid = vpopmail) II.

Hi, I'm not a Blackberry user, but we have some customers currently using an Exchange server with some kind of blackberry and interested in moving their service over to our dovecot 1.1 server Does anyone have any notes or recommendations on getting a (UK) Blackberry to talk effectively to a normal Dovecot server, and are there any things to consider in order to get whatever features they are normally using on their Exchange link working on the Dovecot server? (It's just a small couple of person office on an Exchange server) Thanks for any thoughts/tips Ed W

[Dovecot] cram-md5 and users maintaining their own passwords?
by Steinar Bang 13 Sep '08

13 Sep '08

Is there any other mechanism than using passwd files with md5-hashed passwords created by dovecotpw that will support cram-md5 authentication? Has anyone created setups where the passwd databases reside in the individual users home directories? Is it possible to persuade dovecotpw to update the passwd databases automatically. Having to use a text editor to paste in the passwords sets a high user treshold on using the cram-md5 authentication mechanism. Thanx! - Steinar

[Dovecot] Questions about using sieve
by Robin Atwood 13 Sep '08

13 Sep '08

I am trying to filter my imap mail sent to my phone by using sieve. Currently everything is set up and works well using mbox and sendmail as the lda. I have re-installed dovecot with sieve included and updated dovecot.conf, which gives # dovecot -n # 1.1.3: /etc/dovecot/dovecot.conf ssl_cert_file: /etc/ssl/dovecot/server.pem ssl_key_file: /etc/ssl/dovecot/server.key disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login mail_privileged_group: mail mail_location: mbox:~/mail:INBOX=/var/mail/%u auth default: passdb: driver: pam args: * userdb: driver: passwd and I have added "mail_plugins = cmusieve" to protocol lda{}. I then created a ".dovecot.sieve" script but am not sure where to place it. I tried ~/ and ~/.imap but it never seems to get compiled. Dovecot is running as a root service so it should have access. Setting mail_debug=yes produces no clues, so what should I be looking at? TIA -Robin -- ---------------------------------------------------------------------- Robin Atwood.

[Dovecot] API Examples?
by tcowin 13 Sep '08

13 Sep '08

I need to write a little client to just get the 5 most recent email headers (and \Seen status) from the INBOX of a given user. Are there any API examples anywhere that would speed this process along, or any spots in the source that would give me a jump start? or would it be better to act as an IMAP client? Many Thanks In Advance, Tom -- View this message in context: http://www.nabble.com/API-Examples--tp19444931p19444931.html Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Dovecot 1.1.3 Kerberos5 GSSAPI bug (with patch)
by Matthew Wesley 12 Sep '08

12 Sep '08

The functionality added in changeset 818a638fa9a3 has a bug for x86_64 on line 103. The src/auth/mech-gssapi.c file must now include stdlib.h to have the declaration for getenv(). Otherwise, the compiler uses the implicit return type (int), which truncates the 8-byte pointer getenv() returns to a 4-byte value. This causes a segfault on subsequent reads. Here is debugger output illustrating the problem: (gdb) list 106 101 const char *path; 102 103 path = getenv("KRB5_KTNAME"); 104 if (path != NULL) { 105 #ifdef HAVE_GSSKRB5_REGISTER_ACCEPTOR_IDENTITY 106 gsskrb5_register_acceptor_identity(path); 107 #elif defined (HAVE_KRB5_GSS_REGISTER_ACCEPTOR_IDENTITY) 108 krb5_gss_register_acceptor_identity(path); 109 #endif 110 } (gdb) p/x getenv("KRB5_KTNAME") $32 = 0xb0d7aef7 (gdb) x/s 0xb0d7aef7 0xb0d7aef7: <Address 0xb0d7aef7 out of bounds> (gdb) x/s 0x7fffb0d7aef7 0x7fffb0d7aef7: "/etc/dovecot/dovecot.keytab" A Mercurial bundle with a fix is attached, and here is the trivial patch to put in the needed #include: diff -r 43e55b9af85b src/auth/mech-gssapi.c --- a/src/auth/mech-gssapi.c Mon Sep 01 15:02:49 2008 +0300 +++ b/src/auth/mech-gssapi.c Wed Sep 03 11:37:33 2008 -0400 @@ -22,6 +22,8 @@ #include "safe-memset.h" #ifdef HAVE_GSSAPI + +#include <stdlib.h> #ifndef HAVE___GSS_USEROK # define USE_KRB5_USEROK -- UNIX was not designed to stop you from doing stupid things, because that would also stop you from doing clever things. -- Doug Gwyn

[Dovecot] Public (Shared Folders) ACL Questions
by Mailing List 11 Sep '08

11 Sep '08

I'm trying to set up a public namespace so that a set of IMAP folders are available to all staff - similar to MS Exchange Public Folders. I've managed to set up the namespace correctly but I'm having trouble with the ACLs. The global ACL file is the only method I can get to work. All I want to do is to allow 1 user admin privileges to create & delete anything but all other users should only be able to create not delete. Reading through the mailing list I thought a /etc/dovecot-acls/.DEFAULT file would be suitable but what should be put in here to achieve what I want? Are you able to use wildcards somehow within this file, i.e.: ---------------------------------------- owner lrwstiekxa user=admin(a)domain.com lrwstiekxa user=*(a)domain.com lrw ---------------------------------------- Does this .DEFAULT file only apply to the public (shared) namespace or will it effect private mailboxes also? If I was to create a specific global acl file for a specific folder which would take precedence, the .DEFAULT acls or the specific folder acls? Also an "INBOX" is shown within the public folders namespace but no folder exists in the public folders maildir hierarchy - any ideas how I can stop this? Any help would be greatly appreciated.

[Dovecot] Stumped on adding X-Header...
by Brian Hayden 11 Sep '08

11 Sep '08

Recently I posted about wanting to add an x-header recording a timestamp for changing the \Deleted flag, for purposes of doing expiry on mbox mailboxes. Timo replied: > Be sure to add it to mbox_hide_headers[] and mbox_save_drop_headers[] > arrays in mbox-storage.c and hope that it doesn't exist in any of your > existing mails. :) Other than that there shouldn't be problems. I looked at the two places where X-Status was being written--mbox-save.c and mbox-sync-update.c--and tried adding this header. It didn't work. To test my sanity, I changed the string 'X-Status' in each of these to something else. The mbox file still ended up with 'X-Status' written in it, and I can't for the life of me find any other code that might write that string. Timo? Anyone? -- Brian Hayden UMN OIT Internet Services

[Dovecot] SSL fields as variables for SQL statements ...
by XhE 11 Sep '08

11 Sep '08

Hi, I was wondering if there is any possibility to access the status if a user has provided a certificate, that has been accepted or not via variables. And further if there is any way to get the value of SSL certificate fields by use variables. I'd like to use those variables in sql statements. I then could assign a single certificate to a user, and make up passdb sql statements, that allow him to access multiple (but not all) mailboxes without the need to issue any further certificates. --- Michael

[Dovecot] How to propelry restore a Maildir
by Thomas Hummel 11 Sep '08

11 Sep '08

Hello, I would like to know what is the proper way to restore a Maildir : Assuming someone has got a foobar/[cur|new|tmp] maildir, loses for some reason its content and that some new mail (seen and/or unseen) comes into that mailbox inbetween (that is before the restore procedure takes place, thus creating the need to merge restored messages and new ones). I'd like to check the following (I don't use deliver but procmail) : 1. the messages filenames are unique in time (meaning that a new message cannot be assigned a name already existing in the backup (the name of an old message), at least for the same mailbox instance : if that's not the case : how can we merge safely ? 2. what naming scheme is used (the left part of the name, before the :2,) ? I've got something like : 1215166123.52887_0.host.dom.ain:2,[...] what are the 1215166123, the 52887 and 0 ? 3. what can we deduce from the last modified date of the file as seen in ls -l ? . when in new/, is it the same as the one in the Received: header or is it when in tmp/ ? . when in cur/, is it the date the client "saw" the message ? What would "saw" mean in that case ? 4. should the dovecot-uidlist and dovecot-keywords be updated after the restore or is it better to let dovecot rearrange them itself ? 5. same question for the index and cache files ?

[Dovecot] Panic in Dovecot 1.1.3: index-mail.c: line 1091: assertion failed: (!mail->data.destroying_stream)
by Peter Eriksson 11 Sep '08

11 Sep '08

Dovecot 1.1.3 Solaris 10 SPARC (Sun Fire T1000) Compiled with Sun Studio 12 compilers. Maildir on NFS Indexes on local disk (UFS). 'dovecot -n' output attached. IMAP process crashes for certain (many, but not all) users when accessing certain folders (in the example below, in crashes when accessing my INBOX, about 1700 mails). I could access other mailboxes without problems. And a simple telnet to the imap port followed by a login works fine. Erased the coredumps (was filling up the system too quickly) so I can't really produce a backtrace right now (had to back down to 1.0.13 again even though that one has another core-dump-generating problem - but that is atleast limited to only one specific user so far).

[Dovecot] Support of client specific flags?
by Steinar Bang 11 Sep '08

11 Sep '08

Gnus use a lot of custom flags to represent the messages state wrt. Gnus. How well are these flags supported in dovecot? How fast are access to them? (Ie. will dovecot have to open the message and parse the headers) Are they supported when using imapsync to transfer messages from a different IMAP server? (I guess I'll find out soon, because I'm using imapsync to transfer messages from a cyrus imap daemon to a dovecot one, as I'm writing this)

Thanks for the patch; I've not seen any issues to do with nfs caching before and we've had this live on very heavily loaded systems for several months now.

[Dovecot] 1.1.3 vs 1.1.2 stability?
by Tomasz K Jarzynka 11 Sep '08

11 Sep '08

Hi, since I've numerous reports of segfaults/crashes/corruptions with Dovecot 1.1.3 with Sieve, I'd like to ask - is 1.1.3 an improvement over 1.1.2 or are there some acknowledged regressions and 1.1.4 is planned to fix that? I'd love to avoid figuring this on a live setup and hope to exploit other admins' courage ;P rgds, -- Tomasz Krzysztof Jarzynka / mob. +48 601 706 601 / HANDLE: TJ950-RIPE Network Information Systems Administrator / tomee(at)genesilico(d-o-t)pl Laboratory of Bioinformatics and Protein Engineering | www.genesilico.pl International Institute of Molecular and Cell Biology | www.iimcb.gov.pl

[Dovecot] NFS performance and 1.1.3 - what can you (unofficially) get away with?
by Jack Stewart 10 Sep '08

10 Sep '08

Hi, Does anyone have experience with bending the NFS recommendations to get better performance? The question is has anyone, with Maildir and the INDEX= on NFS (i.e. dovecot.index and dovecot.index.cache, set mail_nfs_index to no. If so, was it better to turn maildir_copy_preserve_filename to on or did it help to turn if off. The other question is did you play with turning off atime updates or changing the acmin* values? I know that the recommendation is do not do this. Fortunately Timo's screams won't reach my ears for another ten hours. I'm just interested if anyone has done this. You are most welcome to reply offline. I figure that the worst that can happen is that the dovecot.index.cache file will become corrupt, and dovecot will then rebuild it. As long as this doesn't happen all the time, it should not be a big deal. I'm guessing that this is less likely maildir_copy_preserve_filename turned on. My old (courier) servers is that I was able to get away with disabling atime updates and bumping up acmin* but then there was no central index to check. I admit that this is a nutty way to go since part of the whole point of 1.1.X is its NFS settings. Yet this is a place with some pretty nutty users. (i.e. 2+GB inboxes, 100K messages, one/minute connections, ...) ---Jack P.S. As a total aside people migrating from 1.0.X to 1.1.3 may wish to have to use a different INDEX directory in 1.1.3 than the one you used in 1.0.7. Doing this got rid of my index.cache and transaction log error messages. This may be why testing isn't showing anything. P.P.S. I've tried imapproxy for my webmail but it doesn't seem to have made much of a difference on the INDEX I/O.

[Dovecot] Question about subfolders
by Oliver Fromme 10 Sep '08

10 Sep '08

Hi, I've got an old dovecot installation (0.99.10.5) which is used as the back-end for a squirrelmail web mailer. Now I need to decide whether to update it to a newer version of dovecot or to switch to a different software. One feature that I really need is to be able to place messages and subfolders in a folder at the same time. This is with mbox format files (I can't use maildir). The old version of dovecot doesn't seem to support that, you can have either subfolders or messages in a folder, but not both. Does the current version 1.1.3 support it? Best regards Oliver PS: Please CC me because I'm not subscribed to the list. Thank you very much! -- Oliver Fromme, secnetix GmbH & Co. KG, Marktplatz 29, 85567 Grafing b. M.

[Dovecot] Problems to sync
by Lincon Peretto 10 Sep '08

10 Sep '08

Dovecot 1.1.2 Good afternoon, I installed dovecot to work with Exim....my dovecot.conf is like this: #Protocolos suportados protocols = imap log_path = /var/log/dovecot.log info_log_path = /var/log/dovecot-info.log #Desabilitar SSL ssl_disable = yes disable_plaintext_auth = no first_valid_gid = 0 mail_location = mailbox:/usr/home/%u/mail/:INBOX=/var/mail/%u mail_access_groups = mail protocol imap { login_executable = /usr/local/libexec/dovecot/imap-login mail_executable = /usr/local/libexec/dovecot/imap login_greeting_capability = yes } #Otimizacao dotlock_use_excl=yes maildir_copy_with_hardlinks=yes auth_verbose = yes auth_process_size = 256 auth_cache_ttl = 3600 auth default { mechanisms = plain user = root ssl_require_client_cert = no passdb pam { } userdb passwd { } } The problem is that I get to sync with INBOX, but I can't get to sync with the other files... I don't know if this line is correct: mail_location = mailbox:/usr/home/%u/mail/:INBOX=/var/mail/%u If I create a new file by the outlook, this file is created in the server normally..... If someone could help....thanks...

[Dovecot] Output of dovecot -a not sorted
by Charles Marcus 10 Sep '08

10 Sep '08

Hey Timo, I think I've asked you about this before, and I'm sure its not a big priority, but this is really a pain when trying to check default settings... The output of dovecot -a is huge, and the fact that it is not sorted alphabetically (nor is dovecot -n, but thats not as big of a problem, although I'd like to see that sorted as well for consistency) makes it really difficult to find certain settings you are looking for. Any chance of fixing this so it sorts the output alphabetically? Thanks, and thanks for dovecot! -- Best regards, Charles

[Dovecot] Data loss from removing dovecot.index* files?
by John Lightsey 10 Sep '08

10 Sep '08

Hi there, I've been rewriting the courier-dovecot-migrate script to handle dovecot->courier conversions in addition to courier->dovecot. One issue I've found is that when the courier->dovecot conversion is performed a second time (using --overwrite) and the dovecot-uidlist file is written again, Dovecot starts generating errors when accessing the maildir. The simple fix is to remove all of the dovecot.index* files so they are rebuilt when the maildir is scanned again. Is it safe to do this or is information stored in the index files that can't be rebuilt by Dovecot the next time it scans the maildir? J.D.

[Dovecot] Maildirsize file isn't updated after doing POP
by Nitass Sutaveephamochanon 09 Sep '08

09 Sep '08

Hello, I have a problem about updating Maildirsize file. It seems that the Maildirsize file is not updated after user does POP mail from his maildir. I do not want to use any quota limitation in Dovecot. I only want Dovevot to update the Maildirsize file after user retrieves his mail. The Maildirsize file is created by Postfix. Would it be possible to do like this? How can I configure it? Could you please advice me? The Dovecot version is 1.0.7. Thank you very much, Nitass

[Dovecot] No buffer space available
by Rick Romero 09 Sep '08

09 Sep '08

Hi, I'm running Dovecot 1.1.3 on FreeBSD 7.0. In the past couple days, I've been seeing errors like this: Sep 9 08:43:51 sysvol dovecot: pop3-login: socketpair() failed: No buffer space available Sep 9 08:43:51 sysvol dovecot: pop3-login: socket(default) failed: No buffer space available Sep 9 08:43:51 sysvol dovecot: pop3-login: Can't connect to auth server at default: No buffer space available Sep 9 08:25:15 sysvol dovecot: pop3-login: socketpair() failed: No buffer space available pop3-login: Can't connect to auth server at default: No buffer space available What ends up happening is that the port doesn't accept any new connections until there is enough buffer space. Yesterday, I saw it a LOT with POP3 and changed my config login processes: login_process_per_connection: no login_process_size: 256 login_processes_count: 6 This seemed to clear up the issues, but now it's occurring again this morning. I haven't had any of these since I made that change either.. So there's some progress... : Sep 8 12:53:40 sysvol dovecot: Temporary failure in creating login processes, slowing down for now TOP shows: Mem: 267M Active, 5558M Inact, 1637M Wired, 217M Cache, 214M Buf, 87M Free Swap: 4096M Total, 4096M Free At this time, there are 120 imap processes, 10 POP and 1 dovecot and 1 dovecot-auth pop and imap both have 6 login processes. It doesn't seem like a load issue, but obviously something is set too low or unavailable... It's fixed for a period of time when I restart dovecot. I did a netstat -m prior to restart, and after restart, and the only main difference was this line: Before: 11/414/425/12800 4k (page size) jumbo clusters in use (current/cache/total/max) After: 0/425/425/12800 4k (page size) jumbo clusters in use (current/cache/total/max) (After about 5 minutes 'current' went to 3) This machine also runs NFSd and MySQL. Any ideas? Thanks, Rick

[Dovecot] antispam plugin problem with dspam
by Harlan Stenn 09 Sep '08

09 Sep '08

I'm trying to use the dovecot antispam plugin with dspam. I'm running dovecot 1.1.2. Using thunderbird and IMAP, when I drag a spam message from the inbox into the SPAM folder, I get a popup saying "The current command did not succeed. The mail server responded: antispam signature not found. When I look at the message in the maildir folder, I see the dspam signature both in the header of the message and at the end of the body. What's a good way to debug this situation and figure things out? I'm not seeing anything in any log files, and I'm not seeing much in the way of debug capability in the dovecot antispam plugin.

[Dovecot] Sieve, and logging.
by Scott Sharkey 09 Sep '08

09 Sep '08

Hi All, Relatively new to Dovecot - converting from courier-imap. So far, I've got it working with virtual users (postfixadmin tables), and it seems to be working. I'm trying to get sieve working. It's not, so I tried turning up the logging, and putting it into a separate log file to get it out of the syslog for now. I can get the main dovecot to log, but I cannot get any log out of dovecot-deliver. I am thinking of replacing the dovecot-deliver with a shell script to see if it's even being called. Suggestions welcome! -Scott Logs and other relevant info follows: .# 1.1.2: /etc/dovecot/dovecot.conf log_path: /var/log/dovecot.log log_timestamp: %Y-%m-%d %H:%M:%S protocols: imaps pop3s managesieve ssl_ca_file: /etc/ssl/certs/ca.crt ssl_cert_file: /etc/ssl/certs/mail.linuxunlimited.com.crt ssl_key_file: /etc/ssl/private/mail.linuxunlimited.com.key 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 login_greeting_capability(default): yes login_greeting_capability(imap): yes login_greeting_capability(pop3): no login_greeting_capability(managesieve): no first_valid_uid: 2000 mail_privileged_group: mail mail_location: maildir:/home/virtual/%d/%n/Maildir mail_debug: yes 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_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 imap_client_workarounds(default): outlook-idle tb-extra-mailbox-sep imap_client_workarounds(imap): outlook-idle 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 pop3_client_workarounds(managesieve): sieve_storage(default): sieve_storage(imap): sieve_storage(pop3): sieve_storage(managesieve): /home/virtual/%d/%n/sieve sieve(default): sieve(imap): sieve(pop3): sieve(managesieve): ~/.dovecot.sieve auth default: mechanisms: plain login user: nobody passdb: driver: pam passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: passwd 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 plugin: sieve: /home/virtual/%d/%n/sieve ------------------------------------------------------------------------ # 1.1.2: /etc/dovecot/dovecot-sql.conf driver = mysql connect = host=127.0.0.1 dbname=mail user=postfixadmin password=xxxxxxxx default_pass_scheme = MD5-CRYPT password_query = SELECT password FROM mailbox WHERE username = '%u' AND active = 1 user_query = SELECT maildir, 2000 AS uid, 2000 AS gid FROM mailbox WHERE username = '%u' AND active = 1 ------------------------------------------------------------------------ Directories: /home: -rwxrwxrwx 1 root root 0 2008-09-07 23:06 dovecot-deliver.log drwxrwxrwx 2 root root 4096 2008-09-07 22:41 sieve drwxrwx--- 8 vmail vmail 4096 2008-08-27 22:26 virtual /home/sieve: -rw-r--r-- 1 root root 353 2008-09-07 22:41 global_rules.sieve -rw-r--r-- 1 root root 388 2008-09-07 23:22 global_rules.sievec /home/sieve/global_rules.sieve: require ["fileinto"]; require ["imapflags"]; if header :contains "Subject" "TestSPAM" { setflag "\\Seen"; fileinto "Junk"; stop; } ------------------------------------------------------------------------ Section of postfix main.cf virtual_transport = dovecot # limit dovecot service to one at a time... dovecot_destination_recipient_limit = 1 local_transport = virtual transport_maps = proxy:mysql:/etc/postfix/mysql_transport_map.cf ------------------------------------------------------------------------ Section of postfix master.cf # Dovecot Local Delivery Agent dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/deliver -f ${sender} -d ${recipient} ------------------------------------------------------------------------ dovecot.log dovecot: 2008-09-07 23:02:49 Info: Dovecot v1.1.2 starting up dovecot: 2008-09-07 23:02:50 Info: auth-worker(default): mysql: Connected to 127.0.0.1 (mail) dovecot: 2008-09-07 23:03:25 Info: auth-worker(default): mysql: Connected to 127.0.0.1 (mail) dovecot: 2008-09-07 23:03:25 Info: auth-worker(default): mysql: Connected to 127.0.0.1 (mail) dovecot: 2008-09-07 23:03:27 Error: auth-worker(default): pam(ssharkey(a)linuxunlimited.com,24.192.79.39): pam_authenticate() failed: User not known to the underlying authentication module dovecot: 2008-09-07 23:03:27 Info: auth-worker(default): mysql: Connected to 127.0.0.1 (mail)

[Dovecot] cyrus2courier or cyrus2maildir.py, which to choose?
by Steinar Bang 09 Sep '08

09 Sep '08

What's the best utility to use to convert mail folders from a cyrus 2.2.13-10, on a debian 4.0 Etch system, to folders that can be used by dovecot? The http://wiki.dovecot.org/Migration/Cyrus page isn't too clear on what's the difference. cyrus2courier says "It should be able to preserve message UIDs, flags and 26 first keywords." cyrus2maildir.py says "preserves delivery timestamps and \Seen flags." But does that means that what cyrus2maildir.py preserves is in addition to what cyrus2courier preserves? Or is what cyrus2maildir preserves a subset of what cyrus2courier preserves? Thanx! - Steinar
