[Dovecot] Strange checkpassword issue
by Andy Dills 28 Jul '08

28 Jul '08

I'm helping a friend setup a small mailserver using dovecot, and I'm finding a strange problem with checkpasswd that I haven't had on my servers. How is the following debug output even possible? Jul 25 12:12:20 company2 dovecot: auth(default): master out: USER 5 joe home=/var/mail/joe.com/joe/Maildir/ uid=1005 gid=1005 Jul 25 12:12:20 company2 dovecot: pop3-login: Login: user=<joe>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Jul 25 12:12:20 company2 dovecot: POP3(joe): open(/var/mail/joe) failed: Permission denied (euid=1005 egid=1005) I don't see how, when it's clearly getting the correct home directory from checkpassword, that it would then try the default mail directory. (mail_location is commented out, version 1.1.1) Here's the entire auth clause: auth default { mechanisms = plain login passdb checkpassword { args = /usr/local/sbin/checkpassword } userdb prefetch { } user = mailman # 1005,1005 socket listen { master { mode = 0666 } client { path = /var/run/dovecot/auth mode = 0660 user = postfix group = postfix } } } Any suggestions? I'm probably just missing something obvious, not having messed with setting this up for 6 months. Thanks, Andy --- Andy Dills Xecunet, Inc. www.xecu.net 301-682-9972 ---

[Dovecot] Sieve Notify Error
by Leroy Philippe 28 Jul '08

28 Jul '08

Hello, I'm using dovecot 1.1.1 and dovecot-sieve-1.1.5 . I'm very interested in the notify plugin, I've tried many code which have generated some errors (coding errors that have been arrived in the .dovecot.sieve.err) but these errors are fixed. But Notify is still not working, I've the following in mail.log :deliver(webmaster@xxx.net): SIEVE ERROR: Unknown [unimplemented] notify method mailto:phxxx@xxp.comhere is my .dovecot.sieve :require ["fileinto", "notify"];# Move spam to spam folderif exists "X-Spam-Flag" { fileinto "spam"; # Stop here so that we do not reply on spams stop;}notify :method "mailto:phxxx@xxp.com":message "Vous avez recu un message sur votre adresse"; # Don't send any further notifications stop;What's wrong? I've tried example from http://www.ietf.org/internet-drafts/draft-ietf-sieve-notify-12.txt but they are not working.Thanks for helpPhilippe _________________________________________________________________ Invite your mail contacts to join your friends list with Windows Live Spaces.

[Dovecot] odd pam_authenticate() failed: authentication error followed by successful imap-login

28 Jul '08

I am seeing the following errors in my log: Jul 27 18:14:23 aegis dovecot: auth-worker(default_with_listener): pam(user(a)host.org,74.72.46.170): pam_authenticate() failed: authentication error Jul 27 18:14:23 aegis dovecot: imap-login: Login: user=<user(a)host.org>, method=PLAIN, rip=74.72.46.170, lip=206.251.255.39, TLS This happens *only* for virtual users; local UNIX users authenticate without that first error. However, all users are able to view mail, but that default_with_listener (which I setup just so Postfix could use dovecot to authenticate SASL senders) error only occurs for virtual users. Why is default_with_listener getting involved when users are trying to connect to dovecot directly without any involvement of Postfix?

[Dovecot] dovecot.sieve file location?
by kbajwa 28 Jul '08

28 Jul '08

CentOS 5.2 Postfix-2.3.3 Dovecot-1.1.1 Dovecot.Sieve-1.1.5 I have setup with: home_mailbox = Maildir/ (/etc/postfix/main.cf) & mail-location = maildir:~/Maildir (/etc/dovecot.conf) I have created a 'test' user to test Sieve 'Vacation' setup. My questions are: 1. Which folder '.dovecot.sieve' script is copied into? Is it 'home/test' -or- 'home/test/Maildir' or someplace else? 2. '.dovecot.sieve' script parameter ":days 1" means that the reply is sent once a day. Is it possible to send the reply 'immediately'? Kirti

[Dovecot] mail extra field to override default mail_location for only certain users
by Sahil Tandon 27 Jul '08

27 Jul '08

I am running version 1.1.1 with mail_location: maildir:~/Maildir. This is working great as all our users have UNIX accounts with nologin shells. New domains (and their users) are about to come online and we would like to migrate to a setup with virtual mailboxes/users. From the wiki and comments within dovecot.conf, I see it is possible to do this piecemeal so both local and virtual users can co-exist during the transition. My question is how to keep things working as they are for existing users/domains (which will be migrated later), and use the virtual mailboxes (and thus, a different mail_location) exclusively for the new users. I understand that multiple userdbs and passdbs can be specified, and this will take care of authentication. On http://wiki.dovecot.org/VirtualUsers#homedirs it is stated that "The userdb can return the mail extra field to override the default mail_location setting. Usually you shouldn't need this." Where is this mail extra field defined? In the userdb passwd-file or somewhere within dovecot.conf? If the former, would something like this suffice (mind the wrapping): user@domain.org::5000:5000::/home/vhosts/domain.org/:/usr/sbin/nologin::mail=m aildir:/home/vhosts/%d/%n Thanks, -- Sahil Tandon <sahil(a)tandon.net>

Re: [Dovecot] how to store flags \Seen into read-only mailbox?

I was looking for workaround, and tried to use one uid for all users, and ACL plugin to give permissions like: --- owner lrwstiekxa anyone rls --- rls should mean read, lookup and write-seen. Read and lookup works, and as soon as I remove these letters I can't read mail folder.

[Dovecot] Dovecot 1.1.2, SIGABRT on copy mail
by Andreas M. Kirchwitz 25 Jul '08

25 Jul '08

Hi folks, with the brandnew release Dovecot 1.1.2, the daemon killed itself with signal 6 (SIGABRT) when trying to save a mail from the INBOX to another folder. The mail client is PINE 4.64. After reconnecting to the IMAP server, the mail was actually copied to the destination folder, but the original mail was still in the INBOX and not flagged as "deleted". This is the panic: Jul 25 02:13:25 linux dovecot: Panic: IMAP(user2): file index-sync.c: line 39 (index_mailbox_set_recent_uid): assertion failed: (seq_range_exists(&ibox->recent_flags, uid)) Jul 25 02:13:25 linux dovecot: IMAP(user2): Raw backtrace: imap [0x80cf8e0] -> imap [0x80cf93a] -> imap [0x80cf26c] -> imap [0x809d11a] -> imap(index_mailbox_set_recent_seq+0x3e) [0x809d15e] -> imap(mbox_sync+0x105d) [0x80823fd] -> imap [0x807a454] -> imap(index_transaction_commit+0x4e) [0x809ddfe] -> imap(cmd_copy+0x35f) [0x805b26f] -> imap [0x805fd7c] -> imap [0x805fe25] -> imap [0x80605e5] -> imap(client_input+0x5e) [0x80607fe] -> imap(io_loop_handler_run+0x100) [0x80d7230] -> imap(io_loop_run+0x28) [0x80d63c8] -> imap(main+0x4a1) [0x8068321] -> /lib/libc.so.6(__libc_start_main+0xe0) [0x149390] -> imap [0x805a101] Jul 25 02:13:25 linux dovecot: child 7954 (imap) killed with signal 6 Thus, the daemon died somewhere between successfully saving a copy of the mail from INBOX to the destination folder and flagging it to be deleted in the INBOX. Just a couple of minutes later, Dovecot died again. Wanted to save a message from INBOX to another folder. But this time, the message wasn't written to the destination folder. As before, the original mail in the INBOX didn't change any flags. Jul 25 02:22:07 linux dovecot: Panic: IMAP(user2): file message-parser.c: line 770 (message_parser_parse_next_block): assertion failed: (ctx->input->eof || ctx->input->closed || ctx->input->stream_errno != 0 || ctx->broken) Jul 25 02:22:07 linux dovecot: IMAP(user2): Raw backtrace: imap [0x80cf8e0] -> imap [0x80cf93a] -> imap [0x80cf26c] -> imap(message_parser_parse_body+0) [0x80c8ba0] -> imap(message_parser_parse_body+0x1e) [0x80c8bbe] -> imap [0x8095120] -> imap [0x809528c] -> imap(index_mail_get_special+0x3a7) [0x8095757] -> imap [0x8061b94] -> imap(imap_fetch+0x148) [0x80620f8] -> imap(cmd_fetch+0x28e) [0x805bcae] -> imap [0x805fd7c] -> imap [0x805fe25] -> imap [0x80605e5] -> imap(client_input+0x5e) [0x80607fe] -> imap(io_loop_handler_run+0x100) [0x80d7230] -> imap(io_loop_run+0x28) [0x80d63c8] -> imap(main+0x4a1) [0x8068321] -> /lib/libc.so.6(__libc_start_main+0xe0) [0x149390] -> imap [0x805a101] Jul 25 02:22:07 linux dovecot: child 17931 (imap) killed with signal 6 The error cannot be reproduced with these messages. They can be saved/copied now without problems back and forth. I've tried to send more mail and reproduce the problem, but no success. Works perfectly fine. Dovecot 1.1.2 is running on Fedora 8 Linux 32 Bit with all patches and custom OpenSSL 0.9.8h. [ output of "dovecot -n" ] # 1.1.2: /usr/local/dovecot/etc/dovecot.conf ssl_cert_file: /usr/local/dovecot/etc/dovecot.crt ssl_key_file: /usr/local/dovecot/etc/dovecot.key login_dir: /usr/local/dovecot/var/run/dovecot/login login_executable: /usr/local/dovecot/libexec/dovecot/imap-login mail_location: mbox:~/Mail:INBOX=/var/spool/mail/%u auth default: mechanisms: plain login digest-md5 cram-md5 passdb: driver: passwd-file args: /usr/local/dovecot/etc/dovecot.passwd userdb: driver: passwd-file args: /usr/local/dovecot/etc/dovecot.passwd The problem was reported by a user who continued to work with his mail folders. I was only a few seconds too late to grab a copy of the INBOX and index files. Greetings, Andreas

[Dovecot] dovecot.conf permissions
by Dan Horák 24 Jul '08

24 Jul '08

Hi, I have a little problem with defining the right permissions for dovecot.conf. The main problem is that the password for SSL certificates is stored there and the conf file is world readable by default, which makes a security problem [1]. It is not a problem to restrict the permissions to 0600, dovecot will still work, but then deliver cannot work as it reads the conf too, but it runs under arbitrary user. So my last iteration is 0640 as permission and root:mail as ownership, but that expects that deliver is run with group = mail. For the long term solution I would prefer to move the password into a separate config file so the permissions can be properly restricted there. What are your opinions? With regards, Dan [1] https://bugzilla.redhat.com/show_bug.cgi?id=436287 -- Fedora and Red Hat package maintainer

[Dovecot] Delivery notifications
by Brandon Keepers 24 Jul '08

24 Jul '08

I'm working on an application that is backed by Postfix 2.3.8 and Dovecot 1.0.13, configured with virtual domains, for handling messaging. I need to be able to send the notification (such as "You've received a new message on SomeAwesomeService. Click here to check it out", It's evil, I know) to a different email address, such as a mobile device. Eventually, we want to do other things like clear web page caches when a message is received, or sending IM notifications, but that's for another day. So basically, we want to notify our application whenever a new mail is received, and it can do all the magical things that it needs to do. I was hoping to get some feedback on the different approaches I'm looking at. From what I can tell, there's not a way to deliver to multiple virtual transports in postfix, so here's the options I see: * Content filter I could set up a "content filter" that just delivers the mail to the application, and then re-injects it back into postfix. This seems like more work than the other options just because I have to worry about re- injecting the message * Intercept delivery Replace the dovecot deliver command with a custom one that calls the dovecot deliver and then passes the message on to the application. I've written a little proof of concept for this and it seems to work, but just seem shady. * Sieve Dovecot supports Sieve, so I could just have a global sieve script that sends the notifications. This is definitely the solution I'm leaning towards. Are there any better options? Do you think this will have a significant impact on performance? Am I crazy? Thanks, Brandon

[Dovecot] making IMAP quicker on LAN
by Andrew Von Cid 24 Jul '08

24 Jul '08

Hi all, I keep on hitting this problem when migrating new clients from POP or local IMAP servers (hosted on their LAN's) to my Dovecot setup, which is hosted properly in a data center. People usually complain that it's slower and although they're getting a kick ass mail setup it doesn't look good from their point of view. I'm wondering if there is anything I could do to speed it up on their LAN's. What I mean is probably a caching IMAP proxy or some sort of replication to a local Dovecot server. Is this something Dovecot can do? I'd be really grateful for any opinions on how to tackle this problem. Many thanks, Andrew.

[Dovecot] how to store flags \Seen into read-only mailbox?
by seriv＠parkheights.dyndns.org 24 Jul '08

24 Jul '08

Hi, I'm trying to use dovecot for storing mailing lists and read-only access for users. The OS is Solaris, authentication for all readers of these lists are from Ldap through PAM, and one local user "listuser" will receive all mail and store them into it's folders (Maildirs). These maildirs are readable (read-only) for all others and they are shared by setting --- mail_location: maildir:/home/vmail/listuser/Maildir:CONTROL=/home/vmail/%u/Maildir/control:INDEX=/home/vmail/%u/Maildir/index --- Mail became readable because in each mail folder to be shared there is dovecot-shared with mode 064, and all users included into his group. But this is the problem: how to have flag \Seen stored in read-only mailbox? As recorded by rawlog, it is ignored now: --- bash-3.00# cat 20080724-103219-10616.in 3 namespace 4 lsub "" "*" 5 list "" "INBOX" 6 list "" "Trash" 7 create "Trash" 8 select "OmniTI.FreeLotto.Ops" 9 UID fetch 1:* (FLAGS) 10 uid store 1:3 +Flags (\Seen) 11 IDLE DONE 12 close 13 logout bash-3.00# cat 20080724-103219-10616.out * OK [RAWLOG TIMESTAMP] 2008-07-24 10:32:19 * NAMESPACE (("" "."))

Hmm. I don't necessarily see that as a desirable feature because in the case that something is actually wrong with the spam tagging you want to notice it isn't working right. If you really need that, just don't set an error when it happens and do nothing, allowing the move. johannes

[Dovecot] Conversion help
by Jason Frisvold 24 Jul '08

24 Jul '08

Hi there, I'm working on converting my server from using bincimap to dovecot. I seem to be having some trouble with folders, however. Binc was set up like this : depot = "IMAPdir", /* Use Maildir++ style type = "Maildir", /* only Maildir path = "Maildir", /* default path */ auto create inbox = "yes", /* create INBOX in auto subscribe mailboxes = "INBOX", /* list mailboxes umask = "077" /* use this umask I have dovecot set up thusly : mail_location = maildir:/home/vpopmail/domains/%d/%n/Maildir namespace private { separator = / prefix = INBOX/ inbox = yes hidden = yes } The problem is, I'm not seeing any folders.. If I do a listing in the directory, I see this : -rw------- 1 vpopmail vchkpw 35453 Mar 10 2004 bincimap-cache -rw------- 1 vpopmail vchkpw 702 Jul 16 19:20 .bincimap-subscribed -rw------- 1 vpopmail vchkpw 73 Mar 10 2004 bincimap-uidvalidity drwx------ 2 vpopmail vchkpw 532480 Jul 21 11:49 cur -rw------- 1 vpopmail vchkpw 25956 Jul 21 11:49 dovecot.index -rw------- 1 vpopmail vchkpw 35840 Jul 21 11:49 dovecot.index.cache -rw------- 1 vpopmail vchkpw 18220 Jul 21 11:49 dovecot.index.log -rw------- 1 vpopmail vchkpw 42080 Jul 21 11:34 dovecot.index.log.2 -rw------- 1 vpopmail vchkpw 106631 Jul 21 11:49 dovecot-uidlist drwx------ 2 vpopmail vchkpw 4096 Jul 21 09:38 INBOX drwx------ 5 vpopmail vchkpw 4096 Jul 20 16:17 INBOX\.Drafts drwx------ 5 vpopmail vchkpw 4096 Jul 16 18:53 INBOX\.Learn FP drwx------ 5 vpopmail vchkpw 4096 Jul 20 17:37 INBOX\.Learn Spam drwx------ 5 vpopmail vchkpw 4096 Jul 16 18:56 INBOX\.Sent drwx------ 5 vpopmail vchkpw 4096 Jul 20 17:37 INBOX\.Spam drwx------ 5 vpopmail vchkpw 4096 Jul 21 11:44 INBOX\.Trash drwx------ 2 vpopmail vchkpw 348160 Jul 21 11:53 new -rw------- 1 vpopmail vchkpw 0 Jul 21 11:34 subscriptions drwx------ 2 vpopmail vchkpw 4096 Jul 21 11:53 tmp -rw------- 1 vpopmail vchkpw 72 Jul 16 18:57 uidvalfilename It would appear that I need to use . as my separator, but that doesn't work either..

[Dovecot] v1.1.2 release candidate
by Timo Sirainen 24 Jul '08

24 Jul '08

I've finally read and answered most of the mails on this list. If you haven't received an answer to your question, resend it. There are a couple of tricky mbox issues left, but I'm not sure if I can do anything about them unless someone can show me how to reproduce the problems. There are quite a lot of new features in v1.1.2 actually. Most of them are in plugins so hopefully they shouldn't destabilize anything. Anyway I tought I'd just in case put out a quick release candidate so at least a few people could try it. I'll probably make the final v1.1.2 release in a day or two. So, please test: http://dovecot.org/tmp/dovecot-1.1.2-rc.tar.gz Largest changes since v1.1.1 are: + Added full text search indexing support for Apache Lucene Solr server: http://wiki.dovecot.org/Plugins/FTS/Solr + IMAP SORT: Added X-SCORE sort key for use with Solr searches. + zlib plugin supports now bzip2 also. + quota: All backends now take noenforcing parameter. + Maildir: Add ,S=<size> to maildir filename whenever quota plugin is loaded, even when not using Maildir++ quota. + deliver: Allow lda section to override plugin settings. + deliver: Giving a -m <namespace prefix> parameter now silently saves the mail to INBOX. This is useful for e.g. -m INBOX/${extension} + Added a new maildirlock utility for write-locking Dovecot Maildir. + dict-sql: Support non-MySQL databases by assuming they implement the "INSERT .. ON DUPLICATE KEY" using an INSERT trigger. - SORT: Fixed several crashes/errors with sort indexing. - IMAP: BODYSTRUCTURE is finally RFC 3501 compliant. Earlier versions didn't include Content-Location support. - IMAP: Fixed bugs with listing INBOX. - Maildir: maildirfolder file wasn't created when dovecot-shared file existed on the root directory - deliver didn't expand %variables in namespace location settings. - zlib: Copying non-compressed messages resulted in empty mails (except when hardlink-copying between maildirs). - mbox-snarf plugin was somewhat broken - deliver + Maildir: If uidlist couldn't be locked while saving, we might have assert-crashed

[Dovecot] Problems with deliver and account resolving
by Andreas Podgurski 24 Jul '08

24 Jul '08

Hi! I'm currently setting up my first mailsystem based on dovecot. For a far way, working with dovecot was very convenient, but after I had to integrate deliver, it became massivly painful. My components are postfix as MTA, postgresql as user database and dovecot as IMAP server. When translating the mail adresse into the account name, something goes terribly wrong (Mail adresses modified to protect against spam, think about them in correct format): dovecot: Jul 22 01:48:13 Info: auth(default-listen): master in: USER 1 Andreas.Podgurski_at_MediaGUILD.de service=deliver dovecot: Jul 22 01:48:13 Info: auth(default-listen): prefetch(Andreas.Podgurski_at_MediaGUILD.de): passdb didn't return userdb entries, trying the next userdb dovecot: Jul 22 01:48:13 Info: auth(default-listen): sql(Andreas.Podgurski_at_MediaGUILD.de): SELECT 1011 AS uid,1011 AS gid,'/var/www/jade/mail/' || admin.username AS home,admin.username AS user FROM admin,email WHERE lower(email.local_address) = lower('Andreas.Podgurski') AND email.receiver = admin.id; dovecot: Jul 22 01:48:13 Info: auth(default-listen): auth(Andreas.Podgurski_at_MediaGUILD.de): username changed Andreas.Podgurski_at_MediaGUILD.de -> SunAdmin dovecot: Jul 22 01:48:13 Info: auth(default-listen): master out: USER 1 SunAdmin uid=1011 gid=1011 home=/var/www/jade/mail/SunAdmin deliver(Andreas.Podgurski_at_MediaGUILD.de): Jul 22 01:48:13 Error: mkdir(/var/www/jade/mail/Andreas.Podgurski_at_MediaGUILD.de/cur) failed: Permission denied deliver(Andreas.Podgurski_at_MediaGUILD.de): Jul 22 01:48:13 Info: msgid=<20080721234813.302260(a)gmx.net>: save failed to INBOX: Internal error occurred. Refer to server log for more information. [2008-07-22 01:48:13] As you can see, the account SunAdmin has an email adresse andreas.podgurski_at_mediaguild.de assigned. The database seems to reveil the username correctly, but after that, deliver continues to use the original mail adresse, not the account name returned by the auth master. Any idea, where my solution went the wrong way? The uid/gid belong to vmail:vmail, which is used for the auth-master, as well as for running deliver and to dispatch the postfix messages. Btw., I ask myself, how dovecot can assume to use prefetch in this case, as prefetch bases upon the password query, which has to fail in this case, as there is no password. Shouldn't it not even try to use the prefetch values there...? Thanks in advance, Andreas Podgurski -- Psssst! Schon vom neuen GMX MultiMessenger gehört?
