[Dovecot] auth_debug_passwords only on mismatches?
by Mike 07 Mar '08

07 Mar '08

>From the configuration notes (1.0.10), it sounds like setting 'auth_debug_passwords' will only log the user supplied password if there was a mismatch.. When I set it (with auth_debug=no), I get a good amount of auth debug info, regardless of password matching.. ------ dovecot.conf: # In case of password mismatches, log the passwords and used scheme so the # problem can be debugged. Requires auth_debug=yes to be set. auth_debug_passwords = yes ------ I'm basically looking to just add a "login failed" line, with the username, and supplied passsword when a mismatch occurs.. Is there currently a way to do this without modifying the code? Thanks! -Mike

[Dovecot] v1.1.rc1 released
by Timo Sirainen 07 Mar '08

07 Mar '08

http://dovecot.org/releases/1.1/rc/dovecot-1.1.rc1.tar.gz http://dovecot.org/releases/1.1/rc/dovecot-1.1.rc1.tar.gz.sig Finally the first v1.1 release candidate. Please test so we can have a fully stable v1.1.0 release. v1.1.betas are already running in a few large installations, so I don't expect there to be many bugs left. There are no release critical bugs left and no known crash bugs. There are a few issues I'd like to fix before v1.1.0, but I don't expect to have more than 3-5 release candidates this time (certainly much less than 31 anyway..) Changes since beta16: - ioloop defaults now to best one availablable instead of poll - IMAP SEARCH correctness fixes - Fixed proxy_maybe handling with caching and with mysql - IMAP: ENVELOPE's subject field now always has TABs changed to spaces - Some crashfixes

[Dovecot] dovecot overquota and delete message
by sa 07 Mar '08

07 Mar '08

Hi all, i use dovecot-1.1_rc1 with postfix and maildrop as deliver. The problem is where user gets overquota, at this point he is unable to delete message in pop3 as imap. dovecot.conf has: plugin { quota = maildir } protocol imap { mail_plugins = quota imap_quota } protocol pop3 { mail_plugins = quota } I change it to plugin { quota = maildir:ignore=Trash } and plugin { quota = maildir:storage=100240:ignore=Trash } but the problem persist. I have to del manually maildirsize file to get the user back to delete. Any suggestion ? tnx s

[Dovecot] Not using "." as separator?
by Grant Edwards 07 Mar '08

07 Mar '08

When using maildir storage, is there any way to use something besides "." as the folder separator? I like to use folder names that match people's e-mail addresses (that's a default behavior in mutt), and "." is a pretty popular character in e-mail addresses. Ideally, I'd like to use "/". Is "." allowed in mailbox names when using mbox storage? -- Grant Edwards grante Yow! As President I have at to go vacuum my coin visi.com collection!

[Dovecot] Logging Options
by Steffen Ille 07 Mar '08

07 Mar '08

Dear Listmembers, I tried to figure out how to get statistics not only about the amount of mails which where sent from / to my mailusers, but also about the size in byte (e.g. to compare with other traffic stats) for each of my users. postfix shows me the size of sent mails per user, but afaik I cannot get the size of rcvd mails per user with it. I use the dovecot LDA with postfix and in this lda - logfiles I also cannot see a byte-like size of delivered mails. Is there any possibility get such statistics working? My used versions are (all Debian Etch): dovecot: 1.0.10 postfix: 2.4.6 Regards, Steffen Ille

[Dovecot] Wrong message information reported shortly after delivery
by Ron Avriel 07 Mar '08

07 Mar '08

Hi, If an IMAP fetch is issued some "short" time after a message was delivered with dovecot deliver then dovecot reports wrong (zero) values for that new message. Afterward, it reports the information OK. This causes problems to our IMAP client. The problem is easily reproduced with a large message on a slow machine. I'm using dovecot 1.0.10 Here's a sample trace: 1 uid fetch 1:* fast * 1 FETCH (FLAGS (\Recent) INTERNALDATE "06-Mar-2008 17:20:50 +0200" RFC822.SIZE 3378380 UID 1) * 2 FETCH (FLAGS (\Recent) INTERNALDATE "06-Mar-2008 17:21:40 +0200" RFC822.SIZE 3378380 UID 2) * 3 FETCH (FLAGS (\Recent) INTERNALDATE "06-Mar-2008 17:23:38 +0200" RFC822.SIZE 3378380 UID 3) * 4 FETCH (FLAGS (\Recent) INTERNALDATE "06-Mar-2008 17:40:06 +0200" RFC822.SIZE 3378380 UID 4) 1 OK Fetch completed. ######## Here dovecot reports a new message (5) arrived ######## 1 uid fetch 1:* fast * 1 FETCH (FLAGS (\Recent) INTERNALDATE "06-Mar-2008 17:20:50 +0200" RFC822.SIZE 3378380 UID 1) * 2 FETCH (FLAGS (\Recent) INTERNALDATE "06-Mar-2008 17:21:40 +0200" RFC822.SIZE 3378380 UID 2) * 3 FETCH (FLAGS (\Recent) INTERNALDATE "06-Mar-2008 17:23:38 +0200" RFC822.SIZE 3378380 UID 3) * 4 FETCH (FLAGS (\Recent) INTERNALDATE "06-Mar-2008 17:40:06 +0200" RFC822.SIZE 3378380 UID 4) * 5 EXISTS * 5 RECENT 1 OK Fetch completed. ######## This is where dovecot reports wrong information about message 5 ######## 1 uid fetch 1:* fast * 1 FETCH (FLAGS (\Recent) INTERNALDATE "06-Mar-2008 17:20:50 +0200" RFC822.SIZE 3378380 UID 1) * 2 FETCH (FLAGS (\Recent) INTERNALDATE "06-Mar-2008 17:21:40 +0200" RFC822.SIZE 3378380 UID 2) * 3 FETCH (FLAGS (\Recent) INTERNALDATE "06-Mar-2008 17:23:38 +0200" RFC822.SIZE 3378380 UID 3) * 4 FETCH (FLAGS (\Recent) INTERNALDATE "06-Mar-2008 17:40:06 +0200" RFC822.SIZE 3378380 UID 4) * 5 FETCH (FLAGS (\Recent) INTERNALDATE "01-Jan-1970 00:00:00 +0000" RFC822.SIZE 0 UID 5) 1 OK Fetch completed. ######## The same wrong information is repeated ######## 1 uid fetch 1:* fast * 1 FETCH (FLAGS (\Recent) INTERNALDATE "06-Mar-2008 17:20:50 +0200" RFC822.SIZE 3378380 UID 1) * 2 FETCH (FLAGS (\Recent) INTERNALDATE "06-Mar-2008 17:21:40 +0200" RFC822.SIZE 3378380 UID 2) * 3 FETCH (FLAGS (\Recent) INTERNALDATE "06-Mar-2008 17:23:38 +0200" RFC822.SIZE 3378380 UID 3) * 4 FETCH (FLAGS (\Recent) INTERNALDATE "06-Mar-2008 17:40:06 +0200" RFC822.SIZE 3378380 UID 4) * 5 FETCH (FLAGS (\Recent) INTERNALDATE "01-Jan-1970 00:00:00 +0000" RFC822.SIZE 0 UID 5) 1 OK Fetch completed. ######## The same wrong information is repeated several times ######## 1 uid fetch 1:* fast * 1 FETCH (FLAGS (\Recent) INTERNALDATE "06-Mar-2008 17:20:50 +0200" RFC822.SIZE 3378380 UID 1) * 2 FETCH (FLAGS (\Recent) INTERNALDATE "06-Mar-2008 17:21:40 +0200" RFC822.SIZE 3378380 UID 2) * 3 FETCH (FLAGS (\Recent) INTERNALDATE "06-Mar-2008 17:23:38 +0200" RFC822.SIZE 3378380 UID 3) * 4 FETCH (FLAGS (\Recent) INTERNALDATE "06-Mar-2008 17:40:06 +0200" RFC822.SIZE 3378380 UID 4) * 5 FETCH (FLAGS (\Recent) INTERNALDATE "01-Jan-1970 00:00:00 +0000" RFC822.SIZE 0 UID 5) 1 OK Fetch completed. ######## Trace truncated here ######## ######## Finally, correct information is reported ######## 1 uid fetch 1:* fast * 1 FETCH (FLAGS (\Recent) INTERNALDATE "06-Mar-2008 17:20:50 +0200" RFC822.SIZE 3378380 UID 1) * 2 FETCH (FLAGS (\Recent) INTERNALDATE "06-Mar-2008 17:21:40 +0200" RFC822.SIZE 3378380 UID 2) * 3 FETCH (FLAGS (\Recent) INTERNALDATE "06-Mar-2008 17:23:38 +0200" RFC822.SIZE 3378380 UID 3) * 4 FETCH (FLAGS (\Recent) INTERNALDATE "06-Mar-2008 17:40:06 +0200" RFC822.SIZE 3378380 UID 4) * 5 FETCH (FLAGS (\Recent) INTERNALDATE "06-Mar-2008 17:41:07 +0200" RFC822.SIZE 3378380 UID 5) dovecot -n: # 1.0.10: /etc/dovecot.conf log_timestamp: “%Y-%m-%d %H:%M:%S ” protocols: imap listen: *:143 ssl_disable: yes login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login login_process_per_connection: no first_valid_uid: 150 last_valid_uid: 150 dotlock_use_excl: yes fsync_disable: yes maildir_copy_with_hardlinks: yes maildir_copy_preserve_filename: yes mail_plugins: quota imap_quota auth default: mechanisms: plain login user: nobody master_user_separator: * passdb: driver: sql args: /etc/dovecot-sql.conf passdb: driver: passwd-file args: /etc/dovecot.masterusers master: yes userdb: driver: prefetch userdb: driver: sql args: /etc/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: mail plugin: quota: maildir:storage=1024 Thanks, Ron ____________________________________________________________________________________ Never miss a thing.

[Dovecot] Quota exceeded - ignore setting
by Fabian Lazarski 06 Mar '08

06 Mar '08

Hello, I have a problem if I use the 'ignore' setting in my dovecot.conf A delete operation in the client means that the mail is copied to Trash mailbox. If the user is already over quota the delete operation will fail. Therefore I use the ignore setting, which doesn`t count the quota at all for the given mailbox. But it doesn`t work. I got still a quoted exceeded failure in my client. Here is the plugin part of my dovecot.conf (The trash folder was renamed in Papierkorb on the mailserver): plugin { quota = maildir:storage=0:ignore=Papierkorb acl = vfile:/etc/dovecot/acls } and the appropriate View definition: SELECT u.userid, 999 AS uid, 8 AS gid, rel_homedir(v.volume::text, u.userid::text) AS home, ('maildir:storage='::text || u.quota::text) || ':ignore=Papierkorb'::text AS quota FROM mailuser u, user_volume v WHERE u.userid::text = v.userid::text;iate view definition: here is a section of imap-info.log: dovecot: 2008-03-06 18:30:55 Info: auth(default): master in: REQUEST 184 3289 173 dovecot: 2008-03-06 18:30:55 Info: auth(default): sql(dg-SW3,172.27.60.237): SELECT * FROM dovecotuser WHERE userid = 'dg-SW3'; dovecot: 2008-03-06 18:30:55 Info: auth(default): master out: USER 184 dg-SW3 userid=dg-SW3 uid=999 gid=8 home=mail02/dg/SW3 quota=maildir:storage=2097152:ignore=Papierkorb master_user=master dovecot: 2008-03-06 18:30:55 Info: imap-login: Login: user=<dg-SW3>, method=PLAIN, rip=172.27.x.y, lip=172.27.x.x dovecot: 2008-03-06 18:30:55 Info: auth(default): client in: AUTH 174 PLAIN service=IMAP lip=172.27.x.x rip=172.27.x.y resp=<hidden> dovecot: 2008-03-06 18:30:55 Info: auth(default): passwd-file(master,172.27.x.y,master): lookup: user=master file=/etc/dovecot/dovecot-master.pwd dovecot: 2008-03-06 18:30:55 Info: auth(default): passdb(master,172.27.x.y,master): Master user logging in as dg-SW3 dovecot: 2008-03-06 18:30:55 Info: auth(default): client out: OK 174 user=dg-SW3 Used dovecot Version is 1.0.2 Can someone help?

[Dovecot] two problems with dovecot and antispam-plugin and qmail/vpopmail
by Mario Cardia 06 Mar '08

06 Mar '08

Hi! I'm trying do use antispam plug-in to split spams in different folders. My problem is with backends... I tried dspam backend and now I'm tring mail training backend. With dspam backend the problem is: When I receive a mail then dspam creates a data directory to store his data as it should do it. But when a try to move the message to Spam folder I get an error (could not execute dspam). If I remove de data directory, it works... I can move the message and by doing this de data directory is re-created. So I decided to try mail training backend. My configuration is: antispam_mail_tmpdir = /tmp antispam_mail_spam = spam@%d antispam_mail_notspam = nospam@%d antispam_mail_sendmail = /opt/qmail/bin/sendmail # antispam_mail_sendmail_args = -f;%u But an error occurs. (Failed to send mail) I tried to use qmail-inject instead but the same error occurs. Then i tried to use de args commented (-f;%u) but didn't work yet. I also tried to use a complete e-mail address to spam and notspam parameters... but nothing seems to works. So I created a shell script to use instead a sendmail program to be able to debug de error. The script has these contents: #!/bin/sh /opt/qmail/bin/sendmail 2> /tmp/error.txt The result of this test is: qmail-inject: fatal: unable to parse this line: Return-Path: <mario(a)cardia.com.br>Delivered-To: isharedev.travelnet.com.br-mario(a)isharedev.travelnet.com.br Note that there is not a "\n" between return-path and delivered-to Can someone help me? (Sorry by my english, I'm brazilian) Tks Mário Cardia

Hi, I'm using dovecot1.1 with postfix2.2.5; I configure dovecot.conf following the dovecot-wiki. But i doesn't work. The maillog said 'Can't connect to auth server at /var/run/dovecot//auth-master: No such file or directory' when I send a mail. my Postfix Master.cf configure: dovecot unix - n n - - pipe flags=DRhu user=vmail argv=/usr/local/libexec/dovecot/deliver -f ${sender} -d ${recipient} I just confused that why it needed to be authed again when postfix pipe the mail to dovecot.

[Dovecot] Effects of migration
by Andy Dills 06 Mar '08

06 Mar '08

So, to follow up to my previous thread, we just successfully migrated our NFS-based mail cluster from qmail pop, courier imap, and bincimap to dovecot 1.1rc1. Overall the transition was very smooth, the only unexpected adjustment was having to implement ntpd on each box, rather than doing an hourly ntpdate against our local ntpd server, to prevent dovecot from crashing itself from too much drift. The impact has been severe! Even with NFS-stored indexes, our netapp is seeing 1/6th of the NFS ops per second, and its CPU utilization is now at 1/3rd previous levels. The only user comment thus far was thanking us for bringing IMAP folders out from under INBOX. Dovecot is truly excellent. In my book, Timo joins Wietse Venema and Marc Martinec to form the backbone of the premiere open source mail solution. For now, praise will have to suffice. I do, however, maintain a little IOU list that I intend to fulfill at some point in the future, and Timo is now high on the list. Thanks again!

[Dovecot] Problem with Thunderbird hang, multiple retry to .Sent/.Draft
by tlum 05 Mar '08

05 Mar '08

I have begun havening a problem when sending or when Thunderbird tries to write copy to .Draft. Usually only happens when the message is longer. While in the Thunderbird editor will say "Copying message to Draft folder". It will try indefinitely. The copy is successful but it looks like it is believed to have failed so its retried. Same then happens when sending. Send happens but then hangs on copy to .Sent. Copy works, but apparently is not seen and just keeps getting retried.

[Dovecot] different mail_locations
by Antonio Casado Rodríguez 05 Mar '08

05 Mar '08

Hi all I've mounted a cluster ACTIVE-PASIVE, with the mailbox in a SAN. The user's home are: /Correo/mail/foo/home I use: Postfix, dovecot and dovecot_lda. The folder /san/mail is only show in the active node (switch the virtual ip, filesystem and daemons). How i configure dovecot mail_location?? Now i have: mail_location: maildir:/Correo/mail/%n The problem is that the admin mails in pasive node are in enqueued and not arrive. I need a user with mail_location in /var/spool/mail/foo (in aliases, root: foo)and the rest users in /Correo/mail/ I have seen override mail_executable, but it not work with dovecot_lda and postfix (local mailer). I have thinked about: mail_location: maildir:%h/..

[Dovecot] multiple namespaces, Mac OS X
by David Koski 05 Mar '08

05 Mar '08

After installing a new server with postfix/dovecot I found that the Mac OS X mail client does not see email in subfolders. It seemed to be related to the namespace. From dovecot.conf: namespace private { separator = . prefix = INBOX. inbox = yes hidden = no } After googling I found that I might need to add a default namespace with an empty prefix so I added this: namespace private { separator = . prefix = inbox = yes hidden = no } Then I was able to access mail in subfolders using the Mac mail client. However, using Kmail I can see both namespaces, where all the folders are listed under the inbox at the same level, and where all folders are listed one level below the inbox. I don't really want to keep my "INBOX." prefix so existing accounts remain unchanged. How do I solve this? The current dovecot.conf is below.

[Dovecot] Mercurial repository
by Timo Sirainen 05 Mar '08

05 Mar '08

I removed "dovecot" repository for now. It was almost the same as dovecot-1.1, with the exception that I had forgotten to commit a few things there and also messed up some other commits ("oh, hg export can export multiple changesets at a time, cool. oh, hg import imported it all in one changeset, not cool."). So for now v1.2 code doesn't exist. I'll clone it again from dovecot-1.1 once I have something real to commit. Although I guess that's probably going to be pretty soon.

[Dovecot] Security issue #5: mail_extra_groups setting is often used insecurely
by Timo Sirainen 05 Mar '08

05 Mar '08

mail_extra_groups=mail setting is often used insecurely to give Dovecot access to create dotlocks to /var/mail directory. If you don't use mboxes in /var/mail, make sure this setting is cleared. If you do use /var/mail mboxes and Dovecot gives permission errors without it, do one of the following (in the preferred order): a) Upgrade to v1.0.11 and use the new mail_privileged_group setting instead of mail_extra_groups. b) Make /var/mail sticky and world-writable (chmod 01777 /var/mail) and clear mail_extra_groups setting. c) Make /var/mail sticky (chmod +t /var/mail) and keep mail_extra_groups setting. This fixes the main problem but some may be left. The mail_privileged_group setting is also available as a patch: http://dovecot.org/patches/1.0/dovecot-1.0.10.mail_priv_groups.diff mail_extra_groups setting has existed since Dovecot v0.99.10.6. It's never been enabled by default in the distributed dovecot-example.conf, but some distributions enable it by default (at least Debian). A longer explanation: The main problem is that if users have filesystem access to the mail server, they can create symlinks. Dovecot doesn't try to prevent following symlinks (and I don't think it should) and normally it isn't a problem. But when mail_extra_groups=mail is set: 1a) Maildir: Any files readable by mail group can be read by the user by symlinking the file to their ~/Maildir/cur/. 1b) Any mbox files readable by mail group can be read by the user by symlinking the mbox file to their ~/mail/ directory. These are pretty obvious problems and I didn't think they were all that important. Why would anyone have secret files that are mail group-readable? But apparently those do exist in some systems (maybe accidentally). 2a) mbox: Any files/directories under mail group-writable directories can be created/deleted/renamed by symlinking the directory under ~/mail/. For example ln -s /var/mail ~/mail/var, DELETE var/root will happily delete root's mailbox. This I hadn't thought about before. 2b) Maildir: Pretty much the same thing can be done with maildir but with a little less control. mail_privileged_group setting works by keeping the group in process's saved GID while it's not in use and temporarily switching it to effective GID while dotlocks are created. Currently this is done only when: 1. It's only done for INBOX mbox which doesn't exist under the same location as other mailboxes (so typically under /var/mail). 2. It's used only after initial dotlock creation try failed with EACCES error.

[Dovecot] constant mailbox rebuilding with dovecot 1.0.10
by Philip J. Hollenback 04 Mar '08

04 Mar '08

I've recently upgraded to 1.0.10 in hopes that this problem would go away but no luck. I've got some users at my company with large inboxes on maildir (say 22,000 messages). Their mailboxes are hosted on nfs and dovecot is configured to do dotlocking. Still I see messages like this continually in the logs (sometimes every hour or so): server dovecot: IMAP(user): dotlock /home/user/Maildir/dovecot.index.log.lock was immediately recreated under us server dovecot: IMAP(user): file_dotlock_create() failed with file /home/user/Maildir/dovecot.index.log: No such file or directory server dovecot: IMAP(user): Our dotlock file /home/user/Maildir/dovecot-uidlist.lock was overridden (kept it 0 secs) server dovecot: IMAP(user): Duplicate file in uidlist file /home/user/Maildir/dovecot-uidlist: 1162416499.010493.mbox:2,Sa server dovecot: IMAP(user): Maildir /home/user/Maildir sync: UID inserted in the middle of mailbox (48573 > 1, file = 1162416499.010493.mbox:2,Sa) or this: server dovecot: IMAP(user): dotlock /home/user/Maildir/dovecot.index.log.lock was immediately recreated under us server dovecot: IMAP(user): file_dotlock_create() failed with file /home/user/Maildir/dovecot.index.log: No such file or directory server dovecot: IMAP(user): Duplicate file in uidlist file /home/user/Maildir/dovecot-uidlist: 1167674195.83666_2.tandoori.schrodinger.com:2,Sklwv server dovecot: IMAP(user): Maildir /home/user/Maildir sync: UID inserted in the middle of mailbox (34969 > 1, file = 1167674195.83666_2.server.com:2,Sklwv) server dovecot: IMAP(user): Corrupted transaction log file /home/user/Maildir/dovecot.index.log.2: invalid indexid (1204046496 != 1204055346) it seems that every time this sort of thing happens the mail client (thunderbird) sits and rebuilds it's mailbox info for as long as 20-30 minutes, during which time it is unusable. I suspect this happens with other users as well but since they have smaller inboxes they don't notice the long delays. Also this is not linked to version 1.0.10, I've been seeing on and off with the previous version (1.0rc17). Here's the 'dovecot -n' output. I should add that the default is for users to use mbox but some users (like the above one) use maildir via a separate dovecot.passwd file.

[Dovecot] v1.0.11 released
by Timo Sirainen 04 Mar '08

04 Mar '08

http://dovecot.org/releases/1.0/dovecot-1.0.11.tar.gz http://dovecot.org/releases/1.0/dovecot-1.0.11.tar.gz.sig * mail_extra_groups setting was commonly used insecurely. This setting is now deprecated. Most users should switch to using mail_privileged_group setting, but if you really need the old functionality use mail_access_groups instead. - mbox: Dropped some of the physical size fetch optimizations added in v1.0.8. This makes some commands slower, but should fix the rest of the problems. - IMAP: SEARCH BEFORE/ON/SINCE didn't handle timezones correctly. - ldap: auth_bind was doing lookups using subtree scope instead of the scope specified in config file. - zlib plugin crashfixes by Richard Platel - master passdbs: pass=yes setting was broken with blocking passdbs (e.g. MySQL)

[Dovecot] Missing IMAP folders
by Willem Jan Withagen 04 Mar '08

04 Mar '08

Hi, I'm fresh starting to use dovecot. Before this I used bincimap, mainly because it was very simple to config. I've tried to find the FAQ's and tried searching the archives, but little came up. My current config: server FreeBSD i386, postfix 2.4 dovecot 1.0.10 client: windows 2000 thunderbird 2.0.0.12 after some inital config this starts up, and I even have the advantage that I can save in the Sent folder on the server. However I have over 3500 folders and most of them are more than 3 levels deep. And I only get to see the first top level of directories. Searching and/or subscribing does not bring anything. Does somebody have pointers on how to fix this, other than manually trying to recreate al subscriptions. --WjW

[Dovecot] Index corruption with squirrelmail.
by "Fábio M. Catunda" 03 Mar '08

03 Mar '08

Hi. I don't know if the problem is related with squirrelmail or not, but I started to have index corruption when I started to try squirrelmail. Some informaton about my instalation: dovecot 1.0.5-1 debian package with maildir squirrelmail 1.4.9a-2 debian package Some log information: dovecot: 2008-02-27 08:39:39 Warning: IMAP(<please don't send spam to me>): fscking index file /var/virtual/contactnet.com.br/fcatunda/Maildir/dovecot.index dovecot: 2008-02-27 08:39:39 Error: IMAP(<please don't send spam to me>): Unexpected transaction log desync with index /var/virtual/contactnet.com.br/fcatunda/Maildir/dovecot.index I'm not pretty sure, but it looks like that if I keep my thunderbird open, receive a message and a rule move the message from INBOX to some other folder and then, finally, I try to login in squirrelmail I reveive a message like this: Query: EXPUNGE And in my log file the above message appears. I already deleted dovecot.* files, but the error ocurred again. Any suggestion? Thanks!

[Dovecot] ManageSieve v0.10.1 released for Dovecot 1.1.rc1
by Stephan Bosch 02 Mar '08

02 Mar '08

Hello Dovecot users, I found a few annoying bugs in the ManageSieve implementation. Particularly, v0.10.0 can pollute the tmp directory of the sieve_storage directory with useless compiled script files. Change Log v0.10.1 ------------------- * Fixed bug introduced in v0.10.0: compiled scripts were also written to disk in the sieve/tmp directory and left there. This accumulates much .sievec junk in that directory over time. * Fixed bug in tmp file generation for sieve-storage: errors other than EEXIST would cause the daemon to sleep() loop indefinitely. + Improved log lines to be more recognizable as being generated from managesieve. + Added short proxy configuration explanation to the README file + Added 'Known Issues' section to the README file - Fixed assert bug in sieve-storage occuring when save is canceled. (Last 5 changes were also back ported to new v9.2 ManageSieve version for dovecot-1.0.10, available at http://www.rename-it.nl/dovecot/1.0/) Installation ------------ The short description I provided in my previous mail is still valid: http://www.dovecot.org/list/dovecot/2008-February/028708.html New release: http://www.rename-it.nl/dovecot/1.1/dovecot-1.1-managesieve-0.10.1.tar.gz http://www.rename-it.nl/dovecot/1.1/dovecot-1.1-managesieve-0.10.1.tar.gz.s… Latest patch version is still valid: http://www.rename-it.nl/dovecot/1.1/dovecot-1.1.rc1-managesieve-0.10.0.diff… http://www.rename-it.nl/dovecot/1.1/dovecot-1.1.rc1-managesieve-0.10.0.diff… (my public key (id: 3DFBB4F4) can be found at wwwkeys.pgp.net) Have fun testing the Dovecot ManageSieve service. Don't hesitate to notify me when there are problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl IRC: Freenode, #dovecot, S[r]us

[Dovecot] Dovecots default NTLM Version
by hever＠web.de 02 Mar '08

02 Mar '08

Hi, I'm not sure what NTLM version is used as default by authentication between Outlook and dovecot and I couldn't find it out with a packet sniffer. I think its NTLMv2 but I'm not sure so I'm asking here. I know that NTLMv1 is not secure against a man in the middle. _____________________________________________________________________ Der WEB.DE SmartSurfer hilft bis zu 70% Ihrer Onlinekosten zu sparen! http://smartsurfer.web.de/?mc=100071&distributionid=000000000066

[Dovecot] Sieve management without shell access or homedir
by Tobias Franzén 02 Mar '08

02 Mar '08

Hi. Is there some user friendly application (web based, maybe a webmail addon) that can help a user manage their sieve filtering? My mail users don't have any shell access to the mail host. Most users won't have a regular home directory either. Can I store this sieve information someplace else? Either directly in LDAP, or in some database, or a common directory for all user's sieve files? /Tobias

[Dovecot] Master user doesn't work with 'pass=yes'
by Ron Avriel 02 Mar '08

02 Mar '08

Hi, It seems that master user login does not work with the 'pass=yes' option as recommended and documented. I defined a master user passdb as documented. In addition, I have a passdb sql. If 'pass=yes' is defined then it seems that dovecot recognizes the master login, verifies the master password but then attempts to verify the ***master*** password again with the ***user*** password (?) and fails. If 'pass=yes' is not defined then master login works OK, but if the user does not exist I get a "* BYE Internal login failure. Refer to server log for more information." instead of the usual "NO Authentication failed.". In addition, I'd like to check the SQL users before the master user, because most logins will be done by SQL users. If I place master passdb after passdb SQL then dovecot fails to start with "Last passdb can't have pass=yes". How can I use master password and "pass=yes"? I'm using dovecot 1.0.10. This is the configuration that fails master login: dovecot.conf: auth_master_user_separator=* auth default { passdb passwd-file { args = /usr/local/etc/passwd.masterusers master = yes pass = yes } passdb sql { args = /usr/local/etc/dovecot-sql.conf } userdb prefetch { } userdb sql { args = /usr/local/etc/dovecot-sql.conf } } passwd.masterusers: master:{SHA}aFAMsNWXTaL5dwGZWeeOhWhlTZA= (password is 'masterpass') log file: Feb 18 17:44:27 ha-test1 dovecot: auth(default): client in: AUTH 1 PLAIN service=IMAP secured lip=127.0.0.1 rip=127.0.0.1 resp=AHVzZXIxQGV4YW1wbGUub3JnKm1hc3RlcgBtYXN0ZXJwYXNz Feb 18 17:44:27 ha-test1 dovecot: auth(default): passwd-file(master,127.0.0.1,master): lookup: user=master file=/usr/local/etc/passwd.masterusers Feb 18 17:44:27 ha-test1 dovecot: auth(default): passdb(master,127.0.0.1,master): Master user logging in as user1(a)example.org Feb 18 17:44:27 ha-test1 dovecot: auth-worker(default): sql(user1(a)example.org,127.0.0.1): query: SELECT username as user, password, maildir as userdb_home, concat('maildir:', maildir) as userdb_mail, 150 as userdb_uid, 12 as userdb_gid, concat('maildir:storage=', quota) AS userdb_quota FROM mailbox WHERE username = 'user1(a)example.org' AND active = '1' Feb 18 17:44:27 ha-test1 dovecot: auth-worker(default): sql(user1(a)example.org,127.0.0.1): Password mismatch ***** Here 'masterpass' is compared to the **USER** password hash (?) ******************* Feb 18 17:44:27 ha-test1 dovecot: auth-worker(default): sql(user1(a)example.org,127.0.0.1): PLAIN-MD5(masterpass) != '81dc9bdb52d04dc20036dbd8313ed055' Feb 18 17:44:28 ha-test1 dovecot: auth(default): client out: FAIL 1 user=user1(a)example.org Thanks, Ron ____________________________________________________________________________________ Never miss a thing.

[Dovecot] typo caused dovecot-acl line 1: Unknown ACL ' '

A co-worker edited a dovecot-acl file and accidently introduced a space at the end of a "user=username lrwstie" entry. Fortunately he noticed errors in his own mail client, but I'm not sure what may have happened to other users. Would it be possible to make dovecot more forgiving by ignoring whitespace at the end of ACLS to avoid this issue?

[Dovecot] nfs locking issues...
by John Gray 01 Mar '08

01 Mar '08

I'm running Dovecot 1.1 RC1. I believe I've done all the due diligence for making things working correctly over nfs. But I run into locking issues if I run over nfs. procmail is doing the delivery over nfs. uw-imap was ruining over nfs. dovecot is fine if its on the nfs server (i.e. it has local access to the disk, no nfs) I run into lock deadlocks if I run dovecot over nfs Users are directed to different servers, but a given users will always get the same server (at least until there's no activity for that user for over an hour). This only applies to when running dovecot over nfs. Everybody goes to the nfs server otherwise. Sometimes I can kill all the processes, remove the dot locks, and recover. Something I need to reboot the nfs server to recover. Let me give a run down of the particulars: All the mail is in mbox format. everybody runs linux with kernel 2.6.24.2 (any known nfs locking issues there?). delivery is done via procmail, its locking and dovecot's are both dotlock, fcntl. The nfs mount options are actimeo=3,hard,noatime,rsize=32768,wsize=32768,nfsvers=3 The clocks are in sync. Dovecot.conf: protocols = imap imaps pop3 pop3s login_greeting = imap ready. mail_location = mbox:~/:INBOX=/var/mail/%u mmap_disable = yes mail_nfs_storage = yes mail_nfs_index = yes protocol imap { } protocol pop3 { pop3_uidl_format = %08Xu%08Xv } auth default { mechanisms = plain passdb pam { } userdb passwd { } user = root } dict { } plugin { } Any help would be greatly appreciated.

[Dovecot] quota & delete
by Osvaldo Alvarez Pozo 01 Mar '08

01 Mar '08

Hy I use dovecot with quota support. I did a test with a webmail client (roundcube) & quota= 10 M when I have used 100% of the quota assigned to the mail account , I cannot delete any mail Is it possible to create a kind of warning mail about 80% of quota use or overpass quota for delete operations? Thanks
