[Dovecot] feature or bug on delete?
by Cor Bosman 23 Jul '05

23 Jul '05

RFC 3501 mentions this: The DELETE command MUST NOT remove inferior hierarchical names. For example, if a mailbox "foo" has an inferior "foo.bar" (assuming "." is the hierarchy delimiter character), removing "foo" MUST NOT remove "foo.bar". It is an error to attempt to delete a name that has inferior hierarchical names and also has the \Noselect mailbox name attribute (see the description of the LIST response for more details). It is permitted to delete a name that has inferior hierarchical names and does not have the \Noselect mailbox name attribute. In this case, all messages in that mailbox are removed, and the name will acquire the \Noselect mailbox name attribute. This is what dovecot does: . create foo . OK Create completed. . create foo/bar . OK Create completed. . list "" "*" * LIST (\HasChildren) "/" "foo" * LIST (\HasNoChildren) "/" "foo/bar" . OK List completed. (some other output removed here) . delete foo . OK Delete completed. . list "" "*" * LIST (\HasNoChildren) "/" "foo/bar" . OK List completed. Reading the above section, shouldnt I be seeing a: * LIST (\Noselect \HasChildren) "/" "foo" Regards, Cor

[Dovecot] pop3 authentication failure - password mismatch

[Dovecot] Stable Version
by Marc Perkel 23 Jul '05

23 Jul '05

I'm very new to Dovecot - still testing it - and planing to convert in the futire. I see a lot of rapid development here which I like. But I'm wondering if there is any kind of schedule for blessing 1.0 as official - or - what the custom is for a stable release. Just trying to think about when to jump in. I'm fairly brave, but the feature I need we just added today. -- Marc Perkel - marc(a)perkel.com Spam Filter: http://www.junkemailfilter.com My Blog: http://marc.perkel.com

[Dovecot] 1.0-test78
by Timo Sirainen 22 Jul '05

22 Jul '05

http://dovecot.org/test/ Fixes: - Crashes in non-x86 64bit systems - Bugs in cache file header caching (you probably should delete all dovecot.index.cache files to be sure the bug won't haunt you in future) - FETCH ENVELOPE patch by Chris Wakelin (I'll try to figure out what to do with the list patch later) Known bugs left: - Thunderbird + maildir: moving lots of messages from mailbox to another may cause deadlock (lock timeouts in half a minute or so and fails the operation). - I guess I should try to look at the Thunderbird + POP3 + lots of messages -> DELE error too again.. - I've heard that 1.0-tests are a lot slower than 0.99.x or 1.0-stable when checking new mail (with kmail), ie. client asking STATUS of all mailboxes. I've looked at their strace outputs and the difference (5-10x slower) comes from 1.0-test waiting longer in poll() for client input, which doesn't really make any sense to me. Can anyone verify this or think of reasons why this could happen? Maybe I'm setting some socket option differently, although I don't think I've changed anything..

[Dovecot] dovecot starts and exit immediately? - help needed
by James Sun 22 Jul '05

22 Jul '05

Since nobody answered my previous question on dovecot marking new mails as old mails, I decided to build a version of dovecot of my own to debug. I downloaded and compiled dovecot 1.0 (stable). After setting up the conf file, I ran dovecot but it exited immediate with status 0. As a result, remote client cannot connect and retrieve mails. There is no man page, and I only found two command line options, -F and -c. None of these options seem to matter. Any suggestions? I must have done something simple and wrong here. Jun

[Dovecot] Bug in 0.99.14 mbox handling - mail UIDs are renumbered without bumping UIDVALIDITY
by David McBride 22 Jul '05

22 Jul '05

Package: dovecot-imapd Version: 0.99.14-1 Severity: important Hi, I think I've identified a bug in Dovecot 0.99.14 as packaged and distributed by Debian Sarge. I believe the bug lies in the original Dovecot source, not with any modifications made by Debian. Specifically, this bug deals with Dovecot's handling of message unique identifiers (UIDs) for IMAP clients when using the mbox mailbox storage format. Some background for those not familiar with the details; (I had to look a lot of this stuff up; see also http://www.ietf.org/rfc/rfc2060.txt) --- 8< -------------------------------------------------------------- All IMAP servers are required to maintain unique identifiers for each email in an IMAP mailbox that are persistent between sessions. Dovecot stores the unique identifiers for each email in an mbox in an X-UID header. Clients which maintain a local cache of already-retrieved emails use an email's UID as a key; thus, if the UID of a particular email were to change on a server then the client's cached state would be invalid. To cope with the case that the UIDs need to be invalidated, whether because the original store has been lost or for some other reason, there is also the UIDVALIDITY number. This 32bit integer must be increased to some higher value to indicate that any previously cached email ids are now invalid. In Dovecot-managed mbox files, this number is stored in the X-IMAPbase header in the first message of that mbox and is typically the uid-invalidation time expressed in unix timestamp format (ie the number of seconds elapsed since the epoch.) --- 8< -------------------------------------------------------------- Okay, the actual bug: Dovecot routinely (and apparently unneccessarily) renumbers all of the UIDs in our mbox-backed mailboxes without updating the UIDVALIDITY count. This results in caching mail clients (such as Evolution and Thunderbird) presenting the incorrect email to the user when browsing their mail. Configuration: We are using Dovecot as a standalone daemon (ie without using inetd.) We have configured the default mail environment with the following string: default_mail_env = mbox:%h/Mail/:INBOX=%h/.email:INDEX=MEMORY ie each end-user's primary INBOX is an mbox, ~/.email, and other IMAP folders are also stored as mboxes in the directory ~/Mail/. Indexes are maintained in memory but are not stored on disk. I don't think any of the rest of the configuration is relavant, but I'm happy to detail anything else about the setup if needed. Reproducing the bug: I'm afraid I don't have a proper protocol dump demonstrating this bug, so I'm just going to describe all of the end-user steps to recreate the problem: 1) Connect to the Dovecot IMAP service with a caching mail client, such as Evolution or Thunderbird. Download a local copy of the IMAP server contents of a test mbox-backed mailbox to the local cache. For example, I have a test mbox with old root mail. Messages are numbered from 1 to 163. The most recent message has an X-UID: field of 163. 2) Delete one of the messages in the middle of the mailbox. For example, mark the second-oldest message in the mailbox, which has a UID of 2, for deletion. Expunge the mailbox. 3) The UIDs of the other messages at this point have not been altered. Disconnect from the IMAP server. (With Evolution, I actually had to restart the program to reproduce this bug.) 4) Reconnect to the IMAP service, and allow the client to re-sync. You will find that the X-UID of all of the messages after the one that was deleted have been decremented -- and, if you're using a caching client, all of the message *bodies* will appear to have been shifted down by one. Reading the headers in the mbox file directly, Dovecot has renumbered all of the UIDs from 1 to N but not altered the UIDVALIDITY field: dwm@kalimdor $ grep X-UID: Root X-UID: 1 X-UID: 2 [... all numbers between 2 and 161 follow ...] X-UID: 161 X-UID: 162 dwm@kalimdor $ grep X-IMAPbase: Root X-IMAPbase: 1063356421 162 1063356421 == Sept 2003, when the mailbox was first created. This is a bug. Either Dovecot should not renumber the UIDs of each message, or (if it really is necessary), it should increase the UIDVALIDITY field to some higher number to invalidate the caches stored by any remote clients. This bug wasn't observed when using previous versions of Dovecot (we were previously using 0.99.10.6 before this upgrade without noticing anything broken.) I'm hoping someone familiar with the source tree can identify and suggest a fix relatively quickly; failing that, I'll take a look around to see if I can work out where the problem is and implement a fix it myself. Cheers, David -- David McBride <dwm(a)tastycake.net>

[Dovecot] Changes made to imap descriptor handling in test78?
by Dominic Marks 22 Jul '05

22 Jul '05

Hello, What has changed from test77 to test78 in the way imap manages its descriptors? I upgraded to test78 this morning on a small site which I use as a testbed for testing various things. Running the same copy of my kqueue patch with test77 works quite well [*], with test78 imap has some problems. Here is some debugging output I recorded: Jul 14 12:55:27 egg dovecot: imap-login: Login: user=<dom>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, SSL Jul 14 12:55:30 egg dovecot: IMAP(dom): kqueue was given an unknown descriptor 1, -1: No such file or directory The second line points refers to io_loop_handler_remove, the tcp/ip socket (1) is having the read filter (-1) removed, suspending events from the socket, or at least, that is what should be happening. From kevent(2) for ENOENT: [ENOENT] The event could not be found to be modified or deleted. This suggests to me that we are incorrectly calling io_loop_handler_remove before we should. This error happens immediately after a client opens their mailbox. I have checked pop3 and it does not share the problem. I'm going to have a look at the CVS mail archive to see if I can work out what has changed. [*] Occasionally I was receiving ENOENT in test77 also in io_loop_handler_remove, but only occasionally, perhaps a few times a day for each client. This also didn't occur when opening the mailbox, but some time later. I'm still looking for the trigger for that. Cheers, -- Dominic Marks

[Dovecot] dovecot pop3s delivers new messages as old (unread) messages ...
by James Sun 22 Jul '05

22 Jul '05

I just set up dovecot on fedora core 3 with only pop3s protocol enabled. On my client machine, I use fetchmail to get the mail and then go through procmail and eventually ready by mutt. Everything seems to work fine, except that all new emails are marked old unread emails (i.e., marked with 'O' flag instead of 'N'). This is annoying because some open source lists are so large that I really rely on the "N" flag to read my emails. I tested the same client setting with gmail and my isp (comcast) pop3 accounts. They work fine - new mails are marked as "N". This makes me suspect dovecot is not set up correctly or something on the pop3 server machine is not right. Anybody has an idea? Thanks in advance.

[Dovecot] Double Emails
by Matt Juszczak 22 Jul '05

22 Jul '05

Hi all, I originally posted this on postfix's mailing list but then realized that this COULD be a pop3 server problem since that downloads and deletes mail. This has only been happening since I upgraded from .99 to 1.0-7 ... Our users have been reporting double messages in their inbox, as well as emails that they deleted a long time ago reappearing. The only thing in my maillog is a bunch of: mbox sync: UID inserted in the middle of mailbox /home/sdf/mail/Level3 (6293 > 3) Thats happening for IMAP folder and /var/mail/* mbox folders alike. I can't seem to figure out the problem, but we have at least 50 customers calling in today alone to complain about double messages. More are probably experiencing it and just not calling. Any ideas? Thanks! -Matt

[Dovecot] Another minor IMAP LIST issue
by Chris Wakelin 22 Jul '05

22 Jul '05

I've just noticed that Dovecot 1.0-stable and 1.0-test78 don't include mbox folders with names beginning with "." in the IMAP LIST output. These are often used to store "hidden" folders for storing things like IMAP client configuration (e.g. Pine 4.x, IMHO, Prayer). Usually the user shouldn't be able to see these, but there are occassions when they might. It seems to me to be better to let the client decide. As I understand it, the IMAP RFC suggests that if you can "SELECT folderpath" a folder, you should also be able to list it with 'LIST "" "folderpath"' I've written a patch against 1.0-stable (it also works with test78) to add an extra namespace option "showdotfiles" (default "no"), to include folders beginning with "." (but excluding ".imap" and "." and ".." for obvious reasons!).

[Dovecot] subscriptions vs mailboxlist
by Marc Perkel 22 Jul '05

22 Jul '05

Is there a way to change the name of the .subscriptions file that dovecot looks for to .mailboxlist to be compatible with WU-IMAP? It would be handy for testing and conversion if you had that. BTW - I'm a new user and your software is very well designed. -- Marc Perkel - marc(a)perkel.com Spam Filter: http://www.junkemailfilter.com My Blog: http://marc.perkel.com

[Dovecot] Errors after moving to Maildir from mbox format
by Gabe Granger 22 Jul '05

22 Jul '05

Hi All, Over the weekend I bit the bullet and migrated my entire office from server to another and converted everything from MBOX to Maildir. Althought it took ages and their we're a few little problems along the way, the migration was a complete success with no users reporting any problems(Mbox used to always cause file lock ups) or even noticing anything had changed... Which is great!:) I'm starting to see some issues currently only with my Mail. In the log files I'm getting loads of the following for at lease 20 different emails Jul 19 12:12:27 server imap(Some-user): Error parsing IMAP envelope: "Tue, 27 May 2003 16:33:07 +0100" "Re: 2U rack cases + PSU" (("Some User" NIL "some-user" "somedomain.foo")) (("Some User" NIL "some- user" "somedomain.foo")) (("Some Userr" NIL "some-user" "somedomain.foo")) (("Some User" NIL "some-user" "some-other- domain.foo")) NIL NIL "<000f01c32462$699a7130$7264a8c0@Microtech>" NIL I did a find in my Mail.app on my mac and discovered that although my client can find the message based on Subject, it fails to locate its mailbox/mailfolder when I select the message I get the following response The message from Some User <some=user(a)some-other-domain.foo> concerning “RE: 2U rack cases + PSU” has not been downloaded from the server. You need to take this account online in order to download it. The account is fully online, does or has anyone here come across this error? I'm guessing there is a problem within the email file itself. I'm using ServerSide Debian 3.1 Sendmail 8.13 Dovecot 0.99.14-1 ClientSide OSX 10.4 Mail.app Any help / pointers would be great. Gabe

[Dovecot] Corrupted indices (and accidental checkin)
by Thomas Wouters 22 Jul '05

22 Jul '05

I've seen a number of corrupted-index problems pop up on our test-dovecot servers (used by a few people at the office), and I'm wondering why corrupt indices don't just automatically get deleted ? Something like: if (!MAIL_INDEX_IS_IN_MEMORY(index)) { unlink(index->filepath); } in src/lib-index/mail-index.c:mail_index_set_error() comes to mind. It seems to me like it should work, anyway. You can still treat the error like it's currently treated (as fatal), but at least it won't pop up the next time you try to perform the same action, or trigger the same corrupted entry another way. By the way, I also noticed what is probably an accidental checkin in src/lib-storage/index/maildir/maildir-storage.c:maildir_get_control_path(), where it tries to migrate control files from the default location to the configured location. I think Timo wrote that patch for my colleage Cor, and then accidentily checked it in with: ---------------------------- revision 1.100 date: 2005-06-09 14:31:43 +0000; author: cras; state: Exp; lines: +22 -4 Replaced ':' and ',' character usages with #defines, so they can be changed easily if needed. The patch is 'broken' anyway; it tries to use rename() to move the old control files to the new location, but that doesn't quite work between different filesystems (and that happens to be what we want to do ;). A better way to handle it would probably be to read in the data from the old location, and then write it out to the new location, in a normal load/save procedure. But I think we'll just do the move manually, after all, as it's just a few dozen different accounts at the moment. I'm not sure about the value of the 'implicit' controlfile migration that dovecot currently does. -- Thomas Wouters <thomas(a)xs4all.net> Hi!

[Dovecot] Few questions
by Sebastjan Trepca 22 Jul '05

22 Jul '05

Is there a way to list all keywords a mailbox uses? I fetch flags for all messages and then gorup them, but this is a very nasty solution. What's the situation with full text search? Will it ever be implemented? Is it already? Text search on my 0.99.14 is quite slow. Don't understand why no IMAP server wants to implement this feature. Does Dovecot support plugins? Thank you, Sebastjan

[Dovecot] CR LF in stable

Hello, It seems that mbox format mailboxes holding \r\n (CR + LF) character sequences (instead of \n only) still cause assertion failures when moving messages from one folder to another. -- dovecot: Jul 19 17:14:52 Error: IMAP(dovetest): file istream-raw-mbox.c: line 38 3 (istream_raw_mbox_get_body_size): assertion failed: (rstream->body_offset != ( uoff_t)-1) -- I seems to work in -test78 though.

[Dovecot] deleting folders containing subfolders with thunderbird (mbox format) bug
by John Bramley 22 Jul '05

22 Jul '05

When using Thunderbird (dovecot-0.99.13-3.FC3) on Fedora connecting to dovecot-0.99.13-3.FC3 I am having problems deleting folders which have been created with the 'Allow your new folder to contain: Folders only' option picked. The folder appears to get deleted but upon restarting Thunderbird the folder still appears to be there but clicking on it I get the error: 'The current command did not succeed. The mailserver responded: Mailbox doesn't exist: <mailbox name>'. Upon investigation when creating and deleting a folder called 'bilbo' to contain subfolders only: Thunderbird sends 'create bilbo/' imap command and then 'subscribe bilbo/' Dovecot creates a directory 'bilbo' and adds 'bilbo/' to the .subscriptions file which all works ok. Upon trying to delete the folder and confirming that it should be deleted Thunderbird sends: 'delete bilbo/' dovecot replies 'OK Delete completed' Then thunderbird sends 'unsubscribe bilbo/' dovecot replies 'NO Invalid mailbox name' which Thunderbird ignores and all seems to have gone ok until thunderbird is restarted and the folder reappears in the folder list but nothing can be done with it. I believe that if a client sends an 'unsubscribe' command to a mailbox that is currently subscribed the imap server should unsubscribe it - even if the actual mailbox doesn't exist (unsubscribe and then delete seems to work when testing using telnet to port 143 to send imap commands). Dovecot does allow mailboxes to be unsubscribed if they don't exist if they don't have a tailing '/' character (so deleting folders set to contain only messages in Thunderbird works ok). I expect that everything works ok using Maildir mailboxes because then there is no need to mark folders containing folders with a '/' because all folders can contain messages and folders. For my own purposes I have hacked the mbox_get_mailbox_name_status function in src/lib-storage/index/mbox/mbox-storage.c to add a check to see if the mailbox name is already subscribed to and if it is then return status = MAILBOX_NAME_EXISTS, before the 'if (!mbox_is_valid_create_name(storage, name))' check which is returning status = MAILBOX_NAME_INVALID, which seems to work ok for me. UW-imap works ok I'm surprised at this bug (or am I doing something completely wrong), surely lots of people use Thunderbird with dovecot, do they not create sub-folders in folders, or are they all using Maildir format, or do they never find the 'Server supports folders that contain sub-folders and messages' advanced option so they are never able to create folders within folders in the first place?

[Dovecot] Failed to create storage with data - possible reasons?
by vmstech 22 Jul '05

22 Jul '05

Hi I'm getting this error with my attempt at setting up dovecot for virtual mail accounts: Failed to create storage with data: /home/vhostpath/usersname/Maildir/ I cant establish any cause. I dont think its permissions as it was saying 'Permission denied' till I fixed that and the UID and GID are those of the directories owner. I was prompted bythe log files to set the minimum and maximum uid range, which made the prompt go away, but I still have this problem. Can anyone tell me what else might cause this error?

[Dovecot] Dovecot 0.99.11 config
by nickr 22 Jul '05

22 Jul '05

I am at wits end...So far it seems dovecot is light years ahead of UW-IMAP. Glad to have UW-IMAP behind me...well almost. My setup = Sendmail 8.13.4 with Procmail delivery to /var/spool/mail/<userfile> openssl 0.9.8 dovecot 0.99.11 I want to continue to use the standard mbox with all the user's mail stored in /var/spool/mail/<userfile>. User's are known to this mail server via NIS and ALL data is mounted accress NFS in read only mode on this machine, including ~home directories. I want to run dovecot like UW-IMAP...trying to keep it simple-->mail delivery to mbox /var/spool/mail/<username>. My /etc/dovecot.conf: I tried both default_ mail_env = INBOX:/var/spool/mail/%u:INBOX:INDEX=MEMORY with and with out the INBOX:INDEX=MEMORY I want to disable the indicies feature. We don't need it we're about 20 engineers or so who want to continue to use the /var/spool/mail mbox-the original Sendmail location. Most users are downloading every piece of mail through OutHouse or Pine, aka OutLook. I keep getting failed to create storage meaages in /var/log/maillog...

[Dovecot] Dovecot vs.Clients - strange behaviour, diagnostics sought
by Jeroen Scheerder 22 Jul '05

22 Jul '05

I've been experimenting with dovecot-1.0-stable on Solaris. Storage format is mbox. Dovecot, in test, runs in parallel with an UW IMAP, with dovecot running SSL-only on port 994. It seems to work to some extent: * dovecot runs * authentication works * SSL works * all manual IMAP functionality checks seem to work fine However, I'm running into issues with IMAP clients. * Null client: I started by using telnet as a client, and talking IMAP manually. Seems OK. * Mutt: "mutt -f imap://my.imap.server:994" seems to work well, although mutt keeps reporting details about the SSL certificate, informs me that it belongs to the proper server and is a valid Globalsign-issued certificate -- and keeps insisting I either reject it or accept it once. * Apple Mail (Panther's version, 1.3.11 (v622)) works, though it seems to have problems with large mailboxes. Then again, it had these same problems with other IMAP servers as well. * Thunderbird doesn't work at all. After some waiting, it bums out and reports: Unable to connect to your IMAP server. You may have exceeded the maximum number of conenctions to this server. If so, use the Advanced IMAP Server Settings dialog to reduce the number of cached connections. Note that it never even shows an authentication dialog, and the only thing I see in dovecot's log that relates to Thunderbirds attempt is: dovecot: Jul 20 09:41:09 Info: imap-login: Disconnected: \ Inactivity [131.211.143.87] I'm at a loss as to what's causing this. On the one hand, dovecot seems operational, on the other hand at least one client can do nothing with it. All debugging/logging options are enabled. What am I missing?
