[Dovecot] Keywords (labels) support via virtual folders
by Robert Tomanek 27 Oct '07

27 Oct '07

Hi all, while I am rather a beginner when it comes to IMAP, I was thinking whether it would be possible (and feasible) to implement setting and unsetting of IMAP keywords with the means of virtual folders in Dovecot. The background is that the IMAP keywords seem to be a very useful thing to me: I would often like to be able to 'tag' a message so that it is easy to group with other similar messages and easy to find/ browse later. The problem is that not all IMAP clients support this functionality (as far as I am aware, mine which happens to be The Bat! does not); the only way of achieving similar results is using regular folders for grouping messages but this has several disadvantages, the most prominent one being unable to assign more than one 'tag' to a message this way (without copying a message). What I am thinking of is a server-side 'helper' that intends to achieve functionality similar to native client keywords support by the means of providing 'virtual folders' (as opposed to regular folders that we've known for a long time). The server would expose a list of virtual folders (user defined, either server-side by modifying the configuration, or client-side, by using the existing 'create regular folder' folder functionality but using a special name format that would be recognized by the server to be virtual folder related). These virtual folders would, upon moving a message to them, apply a keyword to the message (but the message would not be moved as it would be the case with regular folders). Upon moving a message from a virtual folder, the keyword would be reset. This means that the messages would not normally be moved from their place in existing hard folder structure but they would additionally be flagged with a keyword (or more of them) and be visible in respective virtual folders. The result is: - keywords support for clients that do not natively support it, - leaving existing message folder structure intact, - support for multiple keywords/ labels per message (one virtual folder = one keyword), - browsing flagged messages via respective virtual folders. What do you think of it? While I've been toying with this and similar ideas for a long time, what I propose above is of course heavily influenced by the recent addition of IMAP access to Gmail ([1]). While I still do not have it enabled for my account, I presume this is how the Gmail labels get translated to IMAP client ([2], [3]).

[Dovecot] few questions about 1.1*
by Daniel 27 Oct '07

27 Oct '07

Hi! I'm testing 1.1, and have some questions. (How) Can I override the default maildir++ quota setting (I mean quota_rule) in the userdb, so that one won't have quota at all. Right now I'm setting a very high limit in the userdb with quota_rule=*:storage=99G in the extra field. Prior to 1.1 I was using 1.0 and had fs quota. I've had set up dovecot so that the indexes were stored on another partition where there were no fs quotas for the users. Now I'm trying to use maildir++ quota, and wondering if there is still any use of keeping the index files on a separate partition. This will be maybe a bit stupid, but do I still need the quota plugin to be loaded in the protocol {imap,pop3,lda} sections if I'm using the above mentioned new 1.1 maildir++ quota? Furthermore, will deliver be aware of the new quota system? Thanks! Daniel

[Dovecot] append bug in 1.1beta4?
by Daniel 26 Oct '07

26 Oct '07

Hi! I'm guessing this is the append bug which is still present in dovecot-1.1beta4?: Info: IMAP(leva): Disconnected: EOF while appending bytes=31665/119125 This happens after sending a mail, and trying upload/copy that mail from my local "Sent" folder to my IMAP server's Sent folder. Daniel

[Dovecot] sieve filtering, rewriting subjects
by Ian P. Christian 26 Oct '07

26 Oct '07

Is it possible to modify an emails subject line in a sieve script? I've seen references to 'addtag' whilst googling, but it appears dovecots implementation doens't support it - are there any other methods? As a side note, can anyone suggest a web based script editor that works? Simply a text area to write the script in would do Thanks, -- Ian P. Christian ~ pookey.co.uk

[Dovecot] SSL help needed - "no root certificate"
by Jim Gottlieb 26 Oct '07

26 Oct '07

Hi. I've spent the past few hours trying to get SSL working right in Dovecot 1.0.5 and now I must turn to you for help. I purchased an SSL certificate from Go Daddy. I pointed ssl_cert_file to the .crt file and ssl_key_file to the .key file, but the client (Mail.app) complains: Mail was unable to verify the identity of this server, which has a certificate issued to "imap.nccom.com". The error was: There is no root certificate for this server. So I tried downloading Go Daddy's root certificate and pointing ssl_ca_file to that file, but that didn't help. So I tried pointing ssl_ca_file to the intermediate certificate sent to me by Go Daddy, but that breaks things to the point where I never even get the above message; just nothing happens at all. I'm not sure what to try next and am happy to entertain any suggestions. Thanks...

[Dovecot] SSL/TLS with Outlook client
by Eli 25 Oct '07

25 Oct '07

I am trying to get TLS to work with Outlook 2007 and I've hit a small problem. Whenever I start it up, I get this error: "The server you are connected to is using a security certificate that cannot be verified. The target principal name is incorrect." (yes/no choice of trusting) I first tried with a wildcard cert (*.elisand.com), and then tried with mail.elisand.com - both certs are from cacert.org and the root CA certs are installed and functioning properly on my system (so the certs should be trusted). I've searched all over Google and such trying to find out why Outlook would give me this error from an IMAP/TLS connection (closest I could find was Exchange related info), and I know this is by no means an Outlook mailing list... though I'm just wondering if anyone else on here has ever encountered this problem before and could point me in the right direction to getting the SSL cert working with Outlook. Thanks in advance!

[Dovecot] POP3/IMAP newbie question

[Dovecot] How to debug slow operation
by zbigniew szalbot 24 Oct '07

24 Oct '07

Hello, I am no programmer at all. I have dovecot set up on two very similar machines. On one of the boxes, the dovecot server has recently been showing slower response times. It feels slower. Where it is slower, dovecot works as an auth server for postfix. I have replaced exim with postfix on that box and I think since then dovecot started to slow down. On the other machine the MTA is exim. I'd like to ask how to go about debugging the problem. Neither machine serves many users, the one that is slower has currently only two. It's a home setup really. Here's the output of dovecot -n # 1.0.5: /usr/local/etc/dovecot.conf protocols: imap imaps pop3 pop3s disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login login_greeting: Server ready. verbose_proctitle: yes first_valid_uid: 125 first_valid_gid: 125 mail_extra_groups: mail mail_location: maildir:/usr/local/virtual/%d/%n mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 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): outlook-idle pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain login passdb: driver: sql args: /usr/local/etc/dovecot-postfix-sql.conf userdb: driver: sql args: /usr/local/etc/dovecot-postfix-sql.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 384 user: postfix group: postfix Many thanks for your suggestions!

[Dovecot] graceful failure when some folders are not available...
by bhayden＠umn.edu 23 Oct '07

23 Oct '07

Hi folks. Quick question in the hopes that someone knows the answer, before I dig in the code some more. In testing a new setup with some long-term archival mbox-format mailboxes stored on an NFS mount, we've found the following: if the mount is unavailable for any reason, the user cannot log into their email at all. Dovecot says: "stat() failed with mbox foo" and dies. This is coming from the mbox sync checks. (It's possible the same happens with a maildir folder--I'm just specifying mbox because that's what we've tested with so far). Is there a way to reconfigure this behavior? I could maybe see a fatal abort if the inbox is unavailable, but for other folders it seems rather... presumptuous. I have to think there's already a way to handle this more gracefully in the config and I'm just not seeing it. Also, does anyone know offhand if this behavior is the same for folders that aren't in the default/inbox namespace? That would seem *really* wrong. Any thoughts? Thanks much, -Brian

This message that I just sent did the error which was a reply. But, a new message I created earlier today after installing Beta 4 worked fine. Maybe it has something to do with replies versus new messages. Jeff

[Dovecot] trying to enable features
by Ray 23 Oct '07

23 Oct '07

Hello all, I'm trying to enable 3 different features in my mail system (postfix, amavisd, dovecot). 1)out of office auto reply 2)script execution based on email 3)automatically add disclaimer/signature to outgoing email (also listed in order of importance to me) I'm looking for pointers to documentation or instructions. It seems that 1 and 2 would best be done in dovecot somewhere, while 3 is probably best implemented in postfix. (my next step is postfix documentation) Can anybody provide any suggestions or pointers to a how to or other documentation? Thanks, Ray

[Dovecot] SEARCH TEXT does not seem to search headers

The RFC says <http://www.isi.edu/in-notes/rfc3501.txt> this: TEXT <string> Messages that contain the specified string in the header or body of the message. But with the current hg tip (see linked rawlogs), SEARCH TEXT provides results disjoint from SEARCH FROM.

[Dovecot] Courier to Dovecot: problems with folders
by Claudio Strizzolo 22 Oct '07

22 Oct '07

Hi all, I am migrating a maildir Courier-IMAP installation to Dovecot. Almost everything seems to work well, but I still have problems accessing subfolders. First let's see what I have done. I used the courier-dovecot-migrate.pl script suggested in http://wiki.dovecot.org/Migration/Courier to convert mailboxes from Courier to Dovecot. No problems here. My dovecot.conf contains this: (...) mail_location = maildir:/mail/vmail/domains/%h namespace private { prefix = INBOX. inbox = yes } (...) The subscriptions file in the mailboxes looks correct to me. It includes all the folders and subfolders, i.e.: Sent Trash Drafts mail.dovecot mail.misc mail.postmaster tools web.apache web.css Folders separated by "." are actually subfolders: mail ---- dovecot | --- misc | --- postmaster I let the configuration of my IMAP clients unchanged from Courier to Dovecot. That is, they specify the "INBOX." prefix, as before. For instance, with Pine: folder-collections=mymail {mymail.example.com/user=John.Smith}INBOX.[] Now the problem: I get different behaviours depending on the client I use to access to Dovecot: - Thunderbird: All the folders are seen correctly. But the whole folders tree is under "Inbox", while with Courier the first-level folders (i.e. Drafts, mail, web) were at the same level of Inbox - Webmail (Squirrelmail 1.4.8): The same as above. - Pine: The folders are apparently correct, and are not under Inbox, but I can access only the first-level folders: the folders containing sub-folders are empty, therefore the subfolders cannot be accessed. Any hints? Thanks in advance Claudio

[Dovecot] Squirrelmail: "ERROR: Connection dropped by IMAP server."
by Jakob Hirsch 22 Oct '07

22 Oct '07

Hi, running the current version from http://hg.dovecot.org/dovecot/ (but the same happens with 1.1.beta3) After yesterday's patches, squirrelmail (tested with 1.4.11 and 1.4.10a) complains when appending to the Sent folder (after sending a message): ERROR: Connection dropped by IMAP server. Query: SELECT "INBOX" dovecot's log says dovecot: IMAP(jh): Disconnected: EOF while appending bytes=12780/37798 I have captured the conversation with tcpdump (http://plonk.de/imap.cap) and it looks like dovecot is closing the connection. With Thunderbird it works just fine. Regards, Jakob

[Dovecot] pam_ldap.so memory leaks?
by Flannery, Andrew 22 Oct '07

22 Oct '07

Hello List, I have a question about dovecot-1.1.0-beta3 but first I'll ramble a little bit: Recently I upgraded a 0.99 installation of dovecot to 1.0.5. All went relatively smoothly until the dovecot-auth process began returning "out of memory" after a day. There is a rather large user base here. The current setup is using passdb pam with blocking=yes, with pam_ldap.so handling most authentication (although in special cases I am using a custom written pam module which I have disabled to eliminate as the source of the leak). The dovecot-auth process' VmRSS size grows by 4k per request and has a limit of 256megs. Unfortunately turning blocking=yes off isn't an option. The reason I must have it turned on is that the custom pam module is changing the username on specific requests. I am trying to pinpoint the memory leak (pam_ldap is my biggest suspect right now though I'm going to try running valgrind on a test system). For now I have set shutdown_clients=no and am restarting dovecot at regular intervals. Okay the question: In dovecot 1.1.0 beta3 I see that blocking=yes is now on, no matter what. Has something been done to address potential memory leaks in pam modules? Thanks, -Andrew

[Dovecot] Best version for production systems?
by Mitch Pirtle 22 Oct '07

22 Oct '07

Hi dovecotters, I have a system running 1.0rc1 right now and am having problems (more on that later). I know that 1.0.5 is "current" but I'm running Debian Stable (Etch) and have reservations of upgrading until nothing works anymore ;-) Do I really need to make the upgrade to 1.0.5, and if so can anyone here point out how to do so using the standard Debian apt-get process? -- Mitch

[Dovecot] Migrating from UW IMAP - pine - Thunderbird - squirrelmail
by Israel Bravo 22 Oct '07

22 Oct '07

Hello! I saw your post to the mailing list (http://www.dovecot.org/list/dovecot/2006-January/010968.html) where you write "A description for pine with imap acces without entering any password is also discussed.", but I didn't find such description in this post. Would you be so kind to point me to some source where it is explained - currently users have to insert the password twice - when they open the shell window and when they start Pine. Another question - may be you can help me: Currently we use Pine with IMAP (dovecot); both INBOX and folder collection are saved on the Linux server. But how to save the "saved-messages" and "sent-mail" folders in the user's home directory on the server? Thank you for help, -- _________________________________________________________ | Israel Bravo Unix system administrator | The faculty of Industrial Engineering & Management, | Technion, 32000 Haifa, Israel | Phone: 972-4-829-4428 http://ie.technion.ac.il/~bravo/ |________________________________________________________

[Dovecot] assertion failed: (mailbox_list_is_valid_existing_name(_list, name))
by Adam McDougall 21 Oct '07

21 Oct '07

When I was initially testing dovecot 1.1b2,3 I had ACLs turned on and encountered this problem below. I had them turned off until now, I'll need to have ACLs working before I can widen testing. I'm not sure how to make "env MAIL=maildir:~/Maildir gdb /tmp/imap" load the ACL plugin so I assume that is why it does not crash; not getting any log either from that, maybe I made a mistake? But when running mutt, I can load it up with the inbox, then when I ask for imap://server/mail/ it crashes with the assertion at the bottom. Let me know if I need to provide more info. Thanks.

[Dovecot] Upgrade from 1.0.1 -> 1.0.5 failed (rc 75)
by Andy Shellam (Mailing Lists) 21 Oct '07

21 Oct '07

Hi, I'm using a mixture of Exim, Dovecot and Deliver. Exim receives the mail and validates the user against our database, then pipes the e-mail to deliver which puts it in the right mailbox. We were running Exim 4.67 and Dovecot 1.0.1, and today I did an in-place upgrade to Dovecot 1.0.5 and Exim 4.68. However, now Exim is failing deliveries saying deliver returned code 75. If I examine the dovecot log file, I'm getting errors like: deliver(andy.shellam-lists(a)mailnetwork.co.uk): Oct 21 17:19:49 Fatal: chroot(/users/mail/andy.shellam-lists(a)mailnetwork.co.uk) failed: Operation not permitted All mailboxes are owned by user "dovecot-mail" and group "localservice", with user and group having full permissions, and other having no access (0770). None of the config files (Exim nor Dovecot's) have changed, nor have permissions on the mailbox paths, and Dovecot can still access the mailboxes through IMAP just fine. If I delete the dovecot log-file and force a mail delivery, the log gets re-created with mode 0644 and owner dovecot-auth:localservice, which confirms the user running dovecot is the same group, so why doesn't it have permissions? I've read on another message that return code 75 is EX_TEMPFAIL, what does this mean?

[Dovecot] Problem building Dovecot from hg

[Dovecot] dovecot? putting wrong seperator in subscriptions file
by Adam McDougall 21 Oct '07

21 Oct '07

My config has folders show up in the root namespace as well as hidden ones like mail/ for compat. In thunderbird when I set the namespace prefix to mail/, I effectively cannot subscribe to folders. You can pull up the folder list, select some folders to subscribe to, hit okay, and nothing changes in thunderbird: 3 subscribe "mail/Spam" 3 OK Subscribe completed. 4 lsub "" "mail/*" 4 OK Lsub completed. What gets put in my subscriptions file: mail.Spam If I manually change my subscriptions file to mail/Spam, it works as expected. # dovecot -n # 1.1.beta3: /usr/local/etc/dovecot.conf ssl_cert_file: /usr/local/etc/apache2/ssl/cert.pem ssl_key_file: /usr/local/etc/apache2/ssl/cert.pem disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login verbose_proctitle: yes first_valid_uid: 1000 first_valid_gid: 0 mail_location: maildir:%h/Maildir:CONTROL=%h/Maildir/dovecot/private/control:INDEX=%h/Maildir/dovecot/private/indexes mail_debug: yes mmap_disable: yes mail_nfs_storage: yes mail_nfs_index: yes mail_plugins: mail_log mail_log_max_lines_per_sec: 0 imap_client_workarounds: delay-newmail netscape-eoh tb-extra-mailbox-sep imap_logout_format: bbytes=%i/%o username=%u namespace: type: private separator: / prefix: mail/ location: maildir:%h/Maildir:CONTROL=%h/Maildir/dovecot/private/control:INDEX=%h/Maildir/dovecot/private/indexes hidden: yes namespace: type: private separator: / inbox: yes list: yes auth default: mechanisms: plain login passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/auth mode: 384 user: postfix group: postfix plugin: acl: vfile:/usr/local/etc/dovecot-acls

[Dovecot] two small low importance issues in 1.1b
by Adam McDougall 21 Oct '07

21 Oct '07

Item 1: I store the indexes and control in their own directory. I noticed in 1.1: 1192 ./private/indexes/.INBOX 32 ./private/indexes/.Trash 1228 ./private/indexes 4 ./private/control/.INBOX/.INBOX 84 ./private/control/.INBOX 4 ./private/control/.Trash/.Trash 12 ./private/control/.Trash 100 ./private/control 1332 ./private .INBOX/.INBOX and .Trash/.Trash are both empty. This was an empty directory, I logged in with thunderbird and looked at the inbox and Trash folders. Item 2: I wanted to try imap_logout_format, forgetting what params it uses and taking a stab at it, but it seems to be ignored? It shows up in dovecot -n. I made it 'bbytes' just to see if the intentional typo would come through, but no: imap_logout_format: bbytes=%i/%o username=%u dovecot: IMAP(mcdouga9): Disconnected: Logged out bytes=439/169567

[Dovecot] dovecot 1.1.beta3 crashes on NetBSD/sparc64 4.0_RC3 with Thunderbird 2.0.0.6
by Lloyd Parkes 21 Oct '07

21 Oct '07

Hi all, I'm getting core dumps from Dovecot when using Thunderbird as a client. Everything is fine when using the Apple Mail client. I've appended the debug dumps to this message so they are out of the way, but they should be read now. I think the problem might be that io->prev and io->next aren't reliably initialised in ioloop.c:io_add. The value that io->prev has when the program crashes is just completely bogus. It isn't aligned correctly, and it doesn't point to anywhere inside the process's memory map. I don't know what *io->next is, but it sure doesn't look like a struct io_file. It doesn't even look like a struct io. Part of the garbage in *io->next is the char sequence "/vol/home/lloyd/Maildir/new" which is part of my mail box. *io is not in the doubly linked list in current_io_look->io_files. I'm guessing that this object has been unlinked already. Some further digging (not shown here) shows that io->callback is notify_callback. It is set to NULL by the time imap crashes. Here are all the gory GDB details: Version: 1.1.beta3 OS: NetBSD 4.0_RC3/sparc64 (a 64 bit big endian architecture) Client: Mozilla Thunderbird 2.0.0.6 bt full: #0 0x00000000001e846c in io_file_unlink (io=0x32e2c0) at ioloop.c:54 No locals. #1 0x00000000001e8568 in io_remove (_io=0x3420a8) at ioloop.c:82 io_file = (struct io_file *) 0x32e2c0 io = (struct io *) 0x32e2c0 #2 0x000000000017a0a4 in index_mailbox_check_remove_all (ibox=0x331048) at index-mailbox-check.c:118 file = (struct index_notify_file *) 0x0 aio = (struct index_notify_io *) 0x3420a0 #3 0x0000000000139850 in maildir_notify_changes (box=0x331048) at maildir-storage.c:824 mbox = (struct maildir_mailbox *) 0x331048 #4 0x00000000001c0724 in mailbox_notify_changes (box=0x331048, min_interval=0, callback=0, context=0x0) at mail-storage.c:544 No locals. #5 0x00000000001c074c in mailbox_notify_changes_stop (box=0x331048) at mail-storage.c:550 No locals. #6 0x00000000001167fc in idle_finish (ctx=0x3380b0, done_ok=true, free_cmd=true) at cmd-idle.c:48 client = (struct client *) 0x334100 #7 0x0000000000116a04 in idle_client_input (ctx=0x3380b0) at cmd-idle.c:90 client = (struct client *) 0x334100 line = 0x33a075 "DONE" #8 0x00000000001ea2ac in io_loop_handler_run (ioloop=0x320080) at ioloop-kqueue.c:149 ctx = (struct ioloop_handler_context *) 0x32e080 events = (struct kevent *) 0x332000 event = (const struct kevent *) 0x332000 tv = {tv_sec = 0, tv_usec = 999441} ts = {tv_sec = 0, tv_nsec = 999441000} io = (struct io_file *) 0x320a80 events_count = 4 t_id = 2 msecs = 1000 ret = 1 i = 0 __PRETTY_FUNCTION__ = "io_loop_handler_run" #9 0x00000000001e8f28 in io_loop_run (ioloop=0x320080) at ioloop.c:303 No locals. #10 0x000000000012d710 in main (argc=1, argv=0xffffffffffffc978, envp=0xffffffffffffc988) at main.c:293 No locals.

[Dovecot] Problems with dovecot 1.1b3
by Adam McDougall 21 Oct '07

21 Oct '07

I am testing dovecot 1.1 betas on a testing system, hoping to take advantage of self repairing and NFS-capable indexes when 1.1 is sensible to put into production. I ran into a number of issues that I did not have with 1.0, and I think I'll just pick one or more at a time and report them rather than try to report every single issue at once, hoping that some of the fixes will solve more than one problem. I started with 1.1b2 just for record, but the issues seem to be present in 1.1b3 as well. I realized yesterday that using the acl plugin may be complicating my testing and results, so I have disabled it for now and am connecting with plaintext IMAP just so I can sniff connections and see what is happening. I am running it on FreeBSD 6.2-stable from Sep 19 2007. First my dovecot -n output: # 1.1.beta3: /usr/local/etc/dovecot.conf ssl_cert_file: /usr/local/etc/apache2/ssl/ssl.pem ssl_key_file: /usr/local/etc/apache2/ssl/ssl.pem disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login verbose_proctitle: yes first_valid_uid: 1000 first_valid_gid: 0 mail_location: maildir:%h/Maildir:CONTROL=%h/Maildir/dovecot/private/control:INDEX=%h/Maildir/dovecot/private/indexes mail_debug: yes mmap_disable: yes mail_nfs_storage: yes mail_nfs_index: yes mail_plugins: mail_log mail_log_max_lines_per_sec: 0 imap_client_workarounds: delay-newmail netscape-eoh tb-extra-mailbox-sep namespace: type: private separator: / prefix: mail/ location: maildir:%h/Maildir:CONTROL=%h/Maildir/dovecot/private2/control:INDEX=%h/Maildir/dovecot/private2/indexes hidden: yes list: yes namespace: type: private separator: / inbox: yes list: yes auth default: mechanisms: plain login passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/auth mode: 384 user: postfix group: postfix plugin: acl: vfile:/usr/local/etc/dovecot-acls The first thing I did was to try to update my dovecot.conf from 1.0 to work with 1.1. When I started dovecot 1.1 for the first time, I noticed it was listening to 143 but not 993, even though my config was designed for ssl/tls in 1.0 without any listen ports specified: # netstat -a | grep LISTEN | grep imap tcp4 0 0 *.imap *.* LISTEN So, I thought I would try specifying the ports in the config: protocol imap { listen = *:143 ssl_listen = *:993 # .. } Success! # netstat -a | grep LISTEN | grep imap tcp4 0 0 *.imaps *.* LISTEN tcp4 0 0 *.imap *.* LISTEN Initially I was then testing using ACLs, but I disabled it to simplify. One of the more basic problems I've seen is the behavior from "list = no/yes". For the sake of simplicity and example, I've disabled most of the additional public and private namespaces from my 1.0 config. I have some private namespaces with prefix "mail/" and "Mail/" that I wish to provide for users for compatability with clients set with those prefixes. In dovecot 1.0, this worked as expected: namespace: type: private separator: / prefix: mail/ hidden: yes But in 1.1b2 or b3, I never seem to get a list of the contents under mail/ when I tell mutt to default to servername/mail/ as the default folder path. Cases: hidden = yes list = yes a0006 LIST "" "mail" * LIST (\Noselect \HasChildren) "/" "mail" a0006 OK List completed. a0007 LIST "" "mail/%" a0007 OK List completed. mutt lists contents of only "../" and selecting it brings me to the imap root with the expected folders. When ../ is followed, I see all my folders as well as all my folders repeated under mail/ prefix. hidden = yes list = no a0006 LIST "" "mail" a0006 OK List completed. a0007 LIST "" "mail/%" a0007 OK List completed. mutt claims "No such folder" hidden = no list = yes a0006 LIST "" "mail" * LIST (\Noselect \HasChildren) "/" "mail" a0006 OK List completed. a0007 LIST "" "mail/%" a0007 OK List completed. mutt lists contents of only "../" and selecting it brings me to the imap root with the expected folders. When ../ is followed, I see all my folders as well as all my folders repeated under mail/ prefix.

[Dovecot] Problem with fts found against Dovecot hg; examples + trace attached
by Asheesh Laroia 21 Oct '07

21 Oct '07

I've been wanting to try out Squat for full-text indexing for a while now, so I finally gave it a whirl. I did a fresh pull from hg. I have it enabled, but it's taking *forever* to do a query. (Using alpine, I issued a Select command for all messages with some word anywhere, which presumably caused the Squat indexer to run.) I think Dovecot is infinite looping. I thought something was wrong when I attached strace to it for five minutes and saw no calls to read() or open(). I can reproduce the "select takes forever" on a tiny Maildir with 5 messages: http://paulproteus.acm.jhu.edu/bug-report/2007-10-21/broken.tar.gz I've also attached the *.in and *.out files that I think are related to this IMAP conversation. On a different IMAP conversation with the same "SEARCH takes forever" problem, I attached a gdb to the running Dovecot and got this backtrace: (gdb) bt #0 parse_next_body_to_boundary (ctx=0x85746e8, block_r=0xbf92325c) at message-parser.c:332 #1 0x080c1b7d in message_parser_parse_next_block (ctx=0x85746e8, block_r=0xbf92325c) at message-parser.c:717 #2 0xb7f582c2 in fts_mailbox_search_next_nonblock (ctx=0x811c0c0, mail=0x811d380, tryagain_r=0xbf9232bb) at fts-storage.c:175 #3 0x0805f3e6 in cmd_search_more (cmd=0x80feec0) at cmd-search.c:74 #4 0x0805f768 in cmd_search_more_callback (cmd=0x80feec0) at cmd-search.c:112 #5 0x080ce8eb in io_loop_handle_timeouts (ioloop=0x80fb250, update_run_now=true) at ioloop.c:264 #6 0x080cf309 in io_loop_handler_run (ioloop=0x80fb250) at ioloop-poll.c:159 #7 0x080ce7c8 in io_loop_run (ioloop=0x80fb250) at ioloop.c:303 #8 0x08068c9c in main (argc=135213400, argv=0xbf923464, envp=0xbf92346c) at main.c:293 So I do know that it's using the fts system. Every few minutes, I've interrupted it in gdb, and I have gotten these messages back from gdb: Program received signal SIGINT, Interrupt. parse_next_body_to_boundary (ctx=0x85746e8, block_r=0xbf92325c) at message-parser.c:332 332 if (data[i] == '\n') { (gdb) cont Continuing.

This sounds like an infinite loop to me if it can't exit this for minutes and minutes. Furthermore, for the past couple of minutes, when I do this: (gdb) print block_r[0] $8 = {part = 0x80f3158, hdr = 0x0, data = 0x8240d08 "\n<DIV><BR></DIV>Perhaps, but it is important to note that this is a dissenting<BR>opinion, not part of the actual text of the Holt bill.<BR><BR><BR>--- In <A href=\"mailto:TrueVote@yahoogroups.com\">Tru"..., size = 8192} I always get the same response back. I've linked to a fairly small Maildir (five messages) that reproduces the problem for me. It's possible that only one of those messages is actually at fault; I haven't tried with any Maildir smaller than five messages. Is there something more I can do to help fix this problem?

[Dovecot] Multiple server sections for SSL
by Wolfram Schlich 21 Oct '07

21 Oct '07

Hi, I would like to achieve the following with my dovecot server: - listen von FQDN 'mail.foo.example.com'/IP 'A' for imaps and pop3s with an SSL certificate for 'mail.foo.example.com' - listen von FQDN 'mail.bar.example.com'/IP 'B' for imaps and pop3s with an SSL certificate for 'mail.bar.example.com' I stumbled over a posting by Timo made in 2004 that got my attention: http://osdir.com/ml/mail.imap.dovecot/2004-07/msg00133.html Now, what is the correct nesting/structure for the server, protocol, auth, dict and plugin section as well as any other (by default) "non-sectional" configuration options (like 'login_greeting')? I failed to find *any* documentation references on this topic :-( TIA. -- Regards, Wolfram Schlich <wschlich(a)gentoo.org> Gentoo Linux * http://dev.gentoo.org/~wschlich/

[Dovecot] Homedir Access without exposing whole Homedir.
by Dan Mahoney, System Admin 21 Oct '07

21 Oct '07

Hello All, Dovecot 1.0.3 I am coming from UW IMAP, and I'm finding for some reason that mail is getting stored in a variety of places (which I believe, is because by default UW imap allowed access to the entire home directory). All files are mbox. My default delivery location is ~/.mail Thus: * At least a couple of my users have mail in ~/INBOX, as well as ~/INBOX.drafts (not many users so I don't really care about this). * Several of my users have their mail folders in their home directory, AND in a mail folder. For example, my "test case" user, had the following .mailboxlist file: mail/Sent mail/Drafts mail/Spam mail/Trash Sent Items Drafts Deleted Items Junk E-mail Now, here's the question. I'd like to make it so that everyone has what they had before, but that any new folders are created in ~/mail/ (so that if I ever DO decide to convert, I know where to look). What I thought would be useful for this is make the default namespace "", but set it hidden. Then define a secondary namespace (mail) and use that. However, when I did this, and got a mailbox list, it still recursively listed every file in the homedir. Is there a simple way to do what I want? -Dan Mahoney -- "Station!" -Bill & Ted's Bogus Journey --------Dan Mahoney-------- Techie, Sysadmin, WebGeek Gushi on efnet/undernet IRC ICQ: 13735144 AIM: LarpGM Site: http://www.gushi.org ---------------------------

[Dovecot] v1.1 QUOTA and inbox quota
by Kristian Vlahovicek 21 Oct '07

21 Oct '07

My mail agent is postfix and by default it imposes the INBOX size of 50 meg. I would like my imap mail clients (I'm using Thunderbird) to "see" this and warn me when my inbox fills up. I tried doing it with the old quota system but wasn't successful. With the new quota rule system it looks like per-mailbox quotas are possible, however when I do this: quota = maildir quota_rule = INBOX:storage=50000 I get an error in the log: Sep 28 02:18:31 discworld dovecot: IMAP(kristian): open((null)) failed: Bad address Sep 28 02:18:31 discworld dovecot: IMAP(kristian): Internal quota calculation error Sep 28 02:20:04 discworld dovecot: IMAP(kristian): open((null)) failed: Bad address Sep 28 02:20:04 discworld dovecot: IMAP(kristian): open((null)) failed: Bad address is there any way to get the inbox quota to work properly? I guess many systems use postfix and have 50M inbox limit so it would really be helpful if this information is pushed somehow through imap to the client. thanks, K

Postfix, by defaults, don't do more than 100 concurrent deliveries with the same transport, local in my case. I raised up auth_worker_max_count to 128, to accomodate 100 potential concurrent deliveries plus some pop3/imaps clients. The problem appears with certain frequency. There is no other info in the log besides the error notification. FWIW: I have auth_debug enabled. In normal operation I can see the LDAP queries: dovecot: Oct 16 09:46:14 Info: auth(default): ldap(foo,x.y.z.w): pass search: base=ou=users,dc=foo,dc=org scope=subtree filter=(uid=foo) fields=uid,userPassword,sldMailbox nevertheless, next to net_connect errors, the ldap related line is something like dovecot: Oct 16 09:46:14 Info: auth(default): ldap(foo,x.y,z,w): unknown user in both cases, the user don't exist in the directory. Don't know is this could be something with the same nature of[1].

[Dovecot] Errata: dovecot + ldap + virtual mailbox: building mail location path
by Claudio Strizzolo 21 Oct '07

21 Oct '07

Hi all again, I've just realized that I did a bad cut&paste in my previous mail, then I rewrite my request. I apologize. I am trying to set up my dovecot configuration using LDAP and virtual mailboxes. I succeeded in authenticating the users correctly with LDAP, but have problems with referencing the correct mail location directory. I manage several domains. The mailboxes are stored under separate directories for each domain: /mail/vmail/domains/writers.com/William.Shakespeare/ /mail/vmail/domains/writers.com/Jack.London/ /mail/vmail/domains/painters.com/Pablo.Picasso/ /mail/vmail/domains/painters.com/Vincent.VanGogh/ Now, I supposed I could build the path by setting the common part of the paths as mail_location into dovecot.conf: mail_location = maildir:/mail/vmail/domains/%h passdb ldap { args = /etc/dovecot-ldap.conf } userdb ldap { args = /etc/dovecot-ldap.conf } userdb prefetch { } and getting the variable part ("domain/user", i.e. writers.com/Jack.London) from the userdb in dovecot-ldap.conf: auth_bind = yes auth_bind_userdn = mail=%u,vd=%d,o=hosting,dc=example,dc=com ldap_version = 3 base = o=hosting,dc=example,dc=com deref = never scope = subtree user_attrs = mail,,mailbox,mail,, user_filter = (&(objectClass=VirtualMailAccount)(accountActive=TRUE)(mail=%u)) pass_attrs = mail=user,userPassword=password,mailbox=userdb_home,mail=userdb_uid,mail =userdb_mail pass_filter = (&(objectClass=VirtualMailAccount)(accountActive=TRUE)(mail=%u)) default_pass_scheme = CRYPT In the LDAP database the fields are something like: mail = Jack.London(a)writers.com mailbox = writers.com/Jack.London uid = Jack.London However, the above does not work. Here is an extract from the log: Oct 16 15:57:07 mymail.example.com dovecot: auth(default): ldap(Jack.London@writers.com,::ffff:127.0.0.1): user search: base=o=hosting,dc=example,dc=com scope=subtree filter=(&(objectClass=VirtualMailAccount)(accountActive=TRUE)(mail=Jack.London(a)writers.com)) fields=mail,mailbox,mail Oct 16 15:57:07 mymail.example.com dovecot: IMAP(Jack.London(a)writers.com): Ambiguous mail location setting, don't know what to do with it: writers.com/Jack.London/ (try prefixing it with mbox: or maildir:) Oct 16 15:57:07 mymail.example.com dovecot: IMAP(Jack.London(a)writers.com): Failed to create storage with data: writers.com/Jack.London Any hints? BTW, I am trying to prefetch, as you see, but I am not sure that works too. Thanks in advance Claudio

Re: [Dovecot] Problem searching with thunderbird
by Jon Essen-Moller 21 Oct '07

21 Oct '07

Hi, Resending this. Does anyone have a clue? -------------- I downloaded the updated files and now I also upgraded to beta2 as you released late last night. Good work maintaining dovecot I have to say. :-) Unfortunately  I still can't search using thunderbird. I get no errors in the log now but thunderbird doesn't find any messages. I have tried updating the index (in thunderbird) but still no messages found. It worked prior to updating. What could the reason be? Best Regards - Jon ps. I also now tried searching in Squirrelmail aswell. Didn't work. ds.

[Dovecot] Incomplete Subject Line
by Bernhard Schmidt 21 Oct '07

21 Oct '07

Hi, since upgrading from 1.0.5 to latest 1.1-hg I get an incomplete subject line for mails autogenerated by one of our systems in the message list (Thunderbird and mutt). When I open the mail the subject line is intact. It appears that the system is using multiline subjects. Example Subject: =?ISO-8859-1?B?SG9zdG1hc3RlcjogMDAwMDEwNjM1OiBOYW1lc2U=?= =?ISO-8859-1?B?cnZlcjogTmV1dmVyZ2FiZSBvZGVyIMRuZGVydW5n?= is printed as Subject: Hostmaster: 000010635: Namese in the Message list and correctly decoded as Subject: Hostmaster: 000010635: Nameserver: Neuvergabe oder Änderung when viewing the message. Bug? Regards, Bernhard

[Dovecot] Namespace Question
by Jeff Grossman 21 Oct '07

21 Oct '07

I installed 1.1Beta2 over 1.0.5 last night. My 1.0.5 setup was running with no problems at all. Stupid me overwrote my dovecot.conf file with a vanilla one. I know I know, backup!!! I am pretty sure my old dovecot.conf file did not specify any namespaces, but I could be mistaken. My Thunderbird and Squirrelmail are working fine on the new 1.1Beta2 setup. But, my smartphone running Windows Mobile 5.0 does not see the inbox or my folders. Does anybody know what might be different between 1.0.5 and 1.1Beta2 in regards to pocket outlook? This is on a Gentoo system. Here is my dovecot-n output. apple dovecot # dovecot -n # 1.1.beta2: /etc/dovecot/dovecot.conf protocols: imap imaps pop3 pop3s listen: [::] ssl_cert_file: /etc/ssl/dovecot/server.pem ssl_key_file: /etc/ssl/dovecot/server.key ssl_cipher_list: ALL:!LOW:!SSLv2 disable_plaintext_auth: no 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 mail_location: maildir:%h/.maildir mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 auth default: passdb: driver: pam args: * userdb: driver: passwd Thanks, Jeff

[Dovecot] Migration Issues UW-POP3
by Albert E. Whale 21 Oct '07

21 Oct '07

I am migrating from UW's POP3 server (mbox), to Dovecote (mbox -> maildir). Anyway, I am concerned about the Logging details offered by Dovecot, as I manage several details from the logging information provided by UW's Syslog information. Here's a sample of the UW information: Oct 7 22:08:39 ns6 ipop3d[15432]: pop3 service init from 66.207.133.233 Oct 7 22:08:39 ns6 ipop3d[15432]: Auth user=aewhale host=ns.ABS-CompTech.com [66.207.133.233] nmsgs=0/0 Oct 7 22:08:39 ns6 ipop3d[15432]: Logout user=aewhale host=ns.ABS-CompTech.com [66.207.133.233] nmsgs=0 ndele=0 The first time I connected to the server to test the information, I got the following: Oct 7 20:22:17 ns6 dovecot: Dovecot v1.0.rc26 starting up Oct 7 20:22:37 ns6 dovecot: pop3-login: Login: user=<aewhale>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Oct 7 20:23:44 ns6 dovecot: POP3(aewhale): Disconnected: Logged out top=0/0, retr=0/0, del=0/800,size=1576887 None of the other connections reported information about the mailbox or the connections. Here is what I see: Oct 7 20:39:14 ns6 dovecot: pop3-login: Disconnected: method=PLAIN, rip=66.207.133.233, lip=66.207.133.228 Oct 7 20:59:42 ns6 dovecot: pop3-login: Disconnected: method=LOGIN, rip=71.162.15.2, lip=66.207.133.228 Oct 7 21:39:12 ns6 dovecot: pop3-login: Disconnected: method=LOGIN, rip=66.207.133.233, lip=66.207.133.228 Oct 7 21:39:42 ns6 dovecot: pop3-login: Disconnected: method=LOGIN, rip=71.162.15.2, lip=66.207.133.228 I never see the POP3 or Login messages any more. Can someone tell me why? Is this not correctly working on my server yet? -- Albert E.

[Dovecot] potential maildir folder rename bug
by pod 21 Oct '07

21 Oct '07

Admittedly not a common situation but: MAIL=maildir:~/tmp/dovecot/Maildir ./src/imap/imap * PREAUTH [CAPABILITY IMAP4rev1 SASL-IR SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN NAMESPACE LOGIN-REFERRALS] Logged in as pod 01 LIST "" * * LIST (\HasNoChildren) "." "INBOX" 01 OK List completed. 02 CREATE a 02 OK Create completed. 03 LIST "" * * LIST (\HasNoChildren) "." "a" * LIST (\HasNoChildren) "."

I was expecting to wind up with two folders "INBOX" and "a.b". Instead I got "INBOX" and "a.b.b". I think the problem is that ".a" gets renamed in the filesystem to ".a.b" before src/lib-storage/index/maildir/maildir-storage.c rename_subfolders() is called, which then finds ".a.b", assumes "b" was a subfolder of "a" so renames it. The following may or may not be an appropriate fix. It certainly feels rather ad hoc and I've not thought too deeply about other circumstances where this code is called. I'd certainly appreciate a second opinion. diff -r 8d6433652a33 src/lib-storage/index/maildir/maildir-storage.c --- a/src/lib-storage/index/maildir/maildir-storage.c Sun Sep 30 18:03:17 2007 +0300 +++ b/src/lib-storage/index/maildir/maildir-storage.c Mon Oct 01 20:13:27 2007 +0100 @@ -937,6 +937,10 @@ static int rename_subfolders(struct inde t_push(); old_listname = t_strconcat(oldname, names[i], NULL); + if (strcmp(old_listname, newname) == 0) { + t_pop(); + continue; + } new_listname = t_strconcat(newname, names[i], NULL); oldpath = maildir_get_path(storage, old_listname); newpath = maildir_get_path(storage, new_listname);

[Dovecot] API problem (noob)
by Lars Stavholm 21 Oct '07

21 Oct '07

I'm a bit of a newbie, especially when it comes to dovecot internals, but nevertheless, I need some help: I'm working on a dovecot plugin, and I would like to copy a mail message from the mail store out to a temporary file, less a few headers: static const char *const exclude_headers[] = { "X-DSPAM-Signature" } strcpy(fname, mktemp(fname)); fd = creat(fname, 0600); mail_get_stream(mail, NULL, NULL, &input); output = o_stream_create_fd_file(fd, 0, TRUE); input = i_stream_create_header_filter(input, HEADER_FILTER_EXCLUDE | HEADER_FILTER_NO_CR, exclude_headers, N_ELEMENTS(exclude_headers), null_header_filter_callback, NULL); o_stream_send_istream(output, input); But all I get in the temp file is the message body, i.e. no headers at all. What am I doing wrong here? My understanding (or hope:) of what the function i_stream_create_header_filter() is supposed to do might not be accurate: I was hoping that it would exclude the aforementioned headers, but leave the rest of the headers as is. Any help appreciated /Lars
