[Dovecot] Ordering mailboxes
by Ian Marlier 16 Oct '03

16 Oct '03

I have a really weird problem. To whit: I compiled dovecot 0.99.10 on two different systems: a linux-ppc box running Debian, and a Mac OS X Server v. 10.2.8. It compiled fine on both. The same Maildir's are being served up on both -- the OS X server exports home directories to the clients via NFS. BUT the OS X box orders mailboxes this way: INBOX Deleted Items Sent Items . . . And the Debian box orders mailboxes this way: INBOX INBOX/Deleted Items INBOX/Sent Items . . . The compilation options were the same in both cases. The dovecot.conf files are essentially identical -- the only changes are the names of the SSL certificates and the name of the dovecot user. What I can't figure out is, why is the ordering of the mailboxes different? This is the Maildir directory list: [network:/Users/foc/Maildir] root# ls -al /Network/Servers/network.uphamscornercs.net/Users/marlier/Maildir/ total 816 drwxrw---- 22 marlier staff 748 Oct 13 19:52 . drwxr-xr-x 64 marlier staff 2176 Oct 10 14:08 .. drwxrw---- 13 marlier staff 442 Oct 13 19:14 .Deleted Items drwxrwxr-x 9 marlier staff 306 Oct 13 19:14 .Dovecot drwxrw---- 12 marlier staff 408 Oct 8 12:26 .Drafts drwxrw---- 7 marlier staff 238 Oct 13 19:28 .INBOX drwxrw---- 13 marlier staff 442 Sep 16 22:59 .Jen drwxrw---- 13 marlier staff 442 Oct 13 18:30 .Klimas List drwxrw---- 13 marlier staff 442 Oct 13 17:57 .Rachel drwxrw---- 13 marlier staff 442 Oct 13 19:14 .Sent Items drwxrw---- 13 marlier staff 442 Oct 13 19:16 .UCCS -rw-rw---- 1 marlier staff 5 Sep 15 20:58 .customflags -rw-rw---- 1 marlier staff 120 Oct 13 18:16 .subscriptions -rw------- 1 marlier staff 296206 Oct 13 19:40 bincimap-cache -rw------- 1 marlier staff 534 Sep 22 17:45 bincimap-subscribed -rw------- 1 marlier staff 197 Sep 16 21:38 bincimap-subscribed.old -rw------- 1 marlier staff 59 Oct 13 19:40 bincimap-uidvalidity drwx------ 3582 marlier staff 121788 Oct 13 19:36 cur -rw------- 1 marlier staff 96421 Oct 13 19:36 dovecot-uidlist drwx------ 2 marlier staff 68 Oct 13 19:36 new drwxrw--w- 2 marlier staff 68 Sep 15 20:58 recov drwx------ 2 marlier staff 68 Oct 13 19:36 tmp [network:/Users/foc/Maildir] root# Any thoughts?

[Dovecot] Ignore purge and delete command
by vikrant＠linmark.com 16 Oct '03

16 Oct '03

Hi, Does anyone know how to ignore the purge or delete command from the imap clients. Actually I created a mail archive and using dovecot and so far I am happy with the performance. But the problem I am facing right now is I do not want the users to delete the mail by themselves and want to disable the purge or delete command. Thanks Vikrant

[Dovecot] dovecot crashes on start
by Timothy 16 Oct '03

16 Oct '03

Hello, I wasn't able to find anything about this on the site that could give me a definite answer, but when I start dovecot it dies immediately. The following is left in the logs. dovecot: Oct 06 20:59:30 Info: Dovecot starting up dovecot: Oct 06 20:59:32 Error: Auth process died too early - shutting down pop3-login: Oct 06 20:59:32 Fatal: fd_send(-1) failed: Broken pipe I thought this might have something to do with chrooting so I tried to disable all of that in the configuration. After that did not work I rebuilt dovecot with minimal configure options (compared to what I used originally) and used a stock configuration changing only the certificate locations so that dovecot would not complain about the certificates missing, still no luck and the same error. I've tried using strace on dovecot but it seems like it hardly ever hangs/dies at the same point. I'm trying to run this on a slackware 9.0 linux based machine. Any suggestions?

[Dovecot] gzipped files in Mail directory
by Olivier Tharan 09 Oct '03

09 Oct '03

Hi, I have been testing dovecot on my own machine before a bigger deployment. Basically I have all my mbox mailboxes in ~/Mail, delivered by procmail. Some mbox's are gzipped because they are archives which I can grep into, but do not want to look at often. When I first launched an IMAP client, dovecot created the indexes (I think) and gave several errors when finding a gzipped file, such as: ,---- | Oct 1 19:53:21 mafate imap(olive): File isn't in mbox format: /home/olive/Mail//Archives/daily.d/mafate.2003.gz `---- After 19 gzipped mbox's, I had the following crash: ,---- | Oct 1 19:53:21 mafate dovecot: child 4923 (imap) killed with signal 10 `---- Does dovecot not like gzipped mbox's? For the moment, all gzipped files are in ~/Mail/.Archives and I can live with it. -- olive

[Dovecot] Line length limitation in dovecot leads to out-of-control process?
by Amelia A. Lewis 09 Oct '03

09 Oct '03

Heylas! I've been copying mailboxes from one dovecot server (on an alpha running debian testing, 0.99.10-9) to another (on an i686 running debian unstable, 0.99.10-9). I encountered a weird problem, which I seem to have resolved by moving a message with a To: line from hell out of the mailbox. Both machines are running maildir. They're not exactly identical, but they're fairly similar, apart from differences in distribution and architecture; they're running the same version of dovecot, supposedly. Specifically, when I copied this folder over to the new location, dovecot went into CPU-feeding frenzy (up to 99.7% of CPU), and stayed there. If I killed the client and tried to look at the same mailbox using a different client (mutt instead of sylpheed), without killing the imap processor on the server, the indexes would be locked, mutt would fall back to reading headers instead, and then would send its imap process into CPU-feeding frenzy when it got to one particular message. After some experimentation, I found the message. Once I moved it out of cur, I could access the mailbox without problems. The odd thing is that I can look at the message on the original machine, but on the machine it was copied to, its mere existence makes the mailbox inaccessible. After a little more exploration (grep ^To name-of-message | wc, on both machines) I seem to have found the issue: the original message has a To: line that is 16504 characters long. In the copy, it's 8192 characters long, and ends in the middle of a <email@address> (line in copy ends: user name <emai, chopped right there). I suspect that it is the *latter* that's causing dovecot to die a messy death. Or, actually, to turn into a very *rude* process that *doesn't* die. It's a really stupid trick to stuff that much into a header line (it's from helixcode in 2000, btw, notifying people that the promised CD is late), and perfectly reasonable to truncate (even to truncate to 1000 characters, per 282[12]). However, I kinda thing dovecot shouldn't choke on the results of truncation, which is what I think is the problem. Amy! -- Amelia A.

Oops, I apologize for my short, breif message that didn't even include what I said it should inlcude =). Here's the deal: OpenDarwin 6.6 (closest relative being Mac OS X 10.2.6) won't build from CVS. Specifically libtoolize doesn't seem to exist (does it even come with libtool?) and the other parts of the "autogen.sh" fail miserably. This time (really) attached is a gzip of the log of autogen.sh: "./autogen.sh >& autogen.log". Thanks for any help! - Jesse

[Dovecot] those assertions
by dovecot＠spam.turbolink.net 06 Oct '03

06 Oct '03

Timo, Just FYI while you're working on the mbox code, I discovered a bug that occasionally causes dovecot to insert a single blank line at the beginning of the mbox, I'm not sure when/how/why. A single blank line seems to really confuse dovecot, and causes the server to crash when somebody connects to an afflicted mbox. ("Error indexing mbox" in the log, and disconects the user right away). I fixed it with lots of ugly code at our site (basically just remember that we skipped an intial blank line when doing other operations, instead of skipping it then forgetting later). I suspect there's a more elegant way to do it. - Mike

[Dovecot] SSL Client Certificate Support
by Bert Koelewijn 06 Oct '03

06 Oct '03

Dear Timo, most modern enterprises make use of a Public Key Infrastructure. It would be nice to have dovecot check a client certificate instead of a password. This makes life much easier and more secure. Mail clients like Mozilla and MS Outlook do support this. What do you think of the following feature request: - Client authenticates with a certificate via SSL. (Like stunnel can) - Dovecot looks the username up in a table with (public key, username) - The mailclient gives a name and password, but dovecot ignores them - Dovecot gives the client access by the username found in the table This way existing mail clients can use this system and you can save your username with an empty password.

[Dovecot] those assertions
by Bernard Blackham 05 Oct '03

05 Oct '03

Hi, I did a bit of digging into the assertions from mbox-rewrite.c (hdr_parsed_size.physical_size == hdr_size). Every time it happens, hdr_size is 0, while hdr_parsed_size.physical_size is non-zero (presumably the correct value). Does this help track it down? I can't manage to get hold of an mbox that causes this though. Another infrequent assertion that's popped up: file message-address.c: line 262 (message_address_write): assertion failed: (addr->domain != NULL) And one that's only ever been spotted once in the last few weeks: file imap-bodystructure.c: line 278 (part_parse_headers): assertion failed: (part->physical_pos >= input->v_offset - start_offset) I'm waiting for them to happen again to provide some more info... Regards, Bernard. -- Bernard Blackham bernard at blackham dot com dot au

[Dovecot] another Dovecot problem
by Tim Miller 05 Oct '03

05 Oct '03

Hi All-- First, thanks to Timo for solving my last issue. I got dovecot up and running on one of my machines, and it does exactly what I want. Now I'm trying to install dovecot on an older box (glibc 2.0.7 Linux kernel 2.0.36), and encountering some problems: -- firstly autoconf/automake does not seem to correctly deal with the madvise function on this system. It detects that we don't have madvise, yet it's prototyped in /usr/include/sys/mman.h. This causes the compilation to fail when dovecot tries to redefine this function. -- I attempted to solve this problem by renaming the function dovecot prototypes to dc_madvise and then changed all the calls in the code (and the implementation) from madvise to dc_madvise. This allows the code to compile correctly. -- However, once the server is installed, it does not appear to work correctly. I can login, but when I try to list my folders or select any folder (one that exists or one that doesn't exist) the connection times out and the following entry is written to the log file: dovecot: Oct 03 05:38:56 Error: login: received another "not listening" notification (if you can't login at all, see src/lib/fdpass.c) I tracked this message down in the source, but didn't see any obvious way to trace back the problem. Does anyone have experience building on this older configuration (the glibc is a Red Hat version, if it makes any difference)? Any ideas on what might be causing this issue? Best, Tim Miller

Well, on our systems the mailbox is in /var/mail in maildir format, and in ~/Mail users have split up their folders in subdirs, in mixed maildir and mbox formats. So if dovecot could support both dotless directory-structured mailbox locations and maildir/mbox mix-n-match in the same tree, that would be excellent for us. Mbox is a better format for archiving. Now if Dovecot could also access (read-only ofcourse) compressed mbox archives ... Food for thought. Just put it on the wishlist ;) Mike.

[Dovecot] Patches
by Jaldhar H. Vyas 05 Oct '03

05 Oct '03

As the freeze for Debian sarge slowly approaches I want to make sure the Dovecot packages are in as good condition as possible. I see there have been a number of patches since 0.99.10. I have added the following patches: * segfault when user home directory is empty * Proper PAM service name * Make suid work on 2.6 kernels Any other patches thatI ought to add. Or better yet, will there be a 0.99.11 soon? -- Jaldhar H. Vyas <jaldhar(a)debian.org> La Salle Debain - http://www.braincells.com/debian/

[Dovecot] Why does dovecot confuse mutt?
by Amelia A Lewis 04 Oct '03

04 Oct '03

Heylas, I just switched my primary mail server from courier imap to dovecot (I've been waiting to do this; dovecot showed up in debian testing for alpha, at last). So, using the same set of maildirs, there are slightly different behaviors. First, of course, dovecot displays the hierarchy as I thought it ought to be, such that INBOX is a sibling of all other top-level boxes, not the parent of everything. This is A Good Thing[tm]. That works as expected. However, as far as mutt is concerned, *every* mailbox has child folders. My muttrc contains the line: set folder=imap://localhost/. (and the home folder is set to imap://localhost/INBOX; the idea is to do all mail munging through the server, never directly touching the maildirs with an MUA). Oh, and I'm using maildir (~/Maildir). In mutt, from the currently-selected mailbox, one can use 'c' to change boxes, and ? displays a navigable folder hierarchy. If a folder contains only mail (no child folders), it shows up as "FolderName", if it has child folders (whether or not it has mail), it shows up as "FolderName.". You can display the mail in a folder that has child folders, but it requires a different keystroke than the default (enter selects a folder, which means showing child folders if there are any, showing mail if there aren't; to display mail in a folder that has child folders, space). This is tripping me up a little, because of course the commands are mostly bred into my fingertips, and it's a difficult adjustment. I hit return, and I see a folder that contains the "child" folder "../". Is this a glitch in mutt's handling of information that I ought to report to mutt maintainers? Is it a glitch in dovecot's presentation of information that I ought to report to ... err, well. *laugh* My other primary mail client seems to cope beautifully with the information that's supplied (sylpheed, if it matters). But then, sylpheed also coped perfectly when courier was supplying information. I gather that courier and dovecot are reporting something slightly different, somehow, but I don't really know what, and I don't know which should be considered "correct". Amy!

[Dovecot] mailbox sorting issue

Thanks for the "junk at end" help.

I'm not 100% sure that this is a Dovecot issue, but I suspect it is, since this doesn't happen if I open the same mailbox locally or with UW-IMAP. I know that Pine makes use of IMAP server-based sorting if it is available. I tried deleting .imap-index* files, just in case, but that didn't help. thanks, Paul

Here's another patch. This one isn't much different from the last patch, except it tries a little harder to make sure that the required fields are returned by the query (like the pgsql module does). One question about how t_strdup works. How and who should memory returned by t_strdup be freed? My patch has a function my_get_str() which returns the value of t_strdup, and then I do this: user.uid = atoi(my_get_str(res, row, "uid")); /* XXX leak */ user.gid = atoi(my_get_str(res, row, "gid")); /* XXX leak */ Will this result in a memory leak?

I'm not sure what you mean by asynchronous database lookups. Do you mean you'd like to be able to fire off a db lookup and then come back later to get the results? Like blocking vs non-blocking? I've pasted what may be relevant mysql documentation below in case it might help answer the question. N db handles could be allocated, giving us N simultaneous lookups. Matt --- From http://www.mysql.com/doc/en/C_API_function_overview.html: There are two ways for a client to process result sets. One way is to retrieve the entire result set all at once by calling mysql_store_result(). This function acquires from the server all the rows returned by the query and stores them in the client. The second way is for the client to initiate a row-by-row result set retrieval by calling mysql_use_result(). This function initialises the retrieval, but does not actually get any rows from the server. In both cases, you access rows by calling mysql_fetch_row(). With mysql_store_result(), mysql_fetch_row() accesses rows that have already been fetched from the server. With mysql_use_result(), mysql_fetch_row() actually retrieves the row from the server. Information about the size of the data in each row is available by calling mysql_fetch_lengths(). After you are done with a result set, call mysql_free_result() to free the memory used for it. The two retrieval mechanisms are complementary. Client programs should choose the approach that is most appropriate for their requirements. In practice, clients tend to use mysql_store_result() more commonly. An advantage of mysql_store_result() is that because the rows have all been fetched to the client, you not only can access rows sequentially, you can move back and forth in the result set using mysql_data_seek() or mysql_row_seek() to change the current row position within the result set. You can also find out how many rows there are by calling mysql_num_rows(). On the other hand, the memory requirements for mysql_store_result() may be very high for large result sets and you are more likely to encounter out-of-memory conditions. An advantage of mysql_use_result() is that the client requires less memory for the result set because it maintains only one row at a time (and because there is less allocation overhead, mysql_use_result() can be faster). Disadvantages are that you must process each row quickly to avoid tying up the server, you don't have random access to rows within the result set (you can only access rows sequentially), and you don't know how many rows are in the result set until you have retrieved them all. Furthermore, you must retrieve all the rows even if you determine in mid-retrieval that you've found the information you were looking for. --- end

[Dovecot] can't read attachments using javamail with dovecot
by Jonas Bosson 03 Oct '03

03 Oct '03

Dear folks, this might be a java-bug, but it seems to occur only when connecting to dovecot-IMAP. UW and Cyrus-ditto works, while when I try to read attachments (base64), I get slapped in the face with this: java.lang.NullPointerException at com.sun.mail.iap.Response.parse(Response.java:99) at com.sun.mail.iap.Response.<init>(Response.java:68) at com.sun.mail.imap.protocol.IMAPResponse.<init>(IMAPResponse.java:31) at com.sun.mail.imap.protocol.IMAPResponse.readResponse(IMAPResponse.java:105) at com.sun.mail.imap.protocol.IMAPProtocol.readResponse(IMAPProtocol.java:153) at com.sun.mail.iap.Protocol.command(Protocol.java:215) at com.sun.mail.imap.protocol.IMAPProtocol.fetch(IMAPProtocol.java:882) at com.sun.mail.imap.protocol.IMAPProtocol.fetch(IMAPProtocol.java:874) at com.sun.mail.imap.protocol.IMAPProtocol.fetchBody(IMAPProtocol.java:677) at com.sun.mail.imap.IMAPInputStream.fill(IMAPInputStream.java:74) at com.sun.mail.imap.IMAPInputStream.read(IMAPInputStream.java:105) at com.sun.mail.util.BASE64DecoderStream.decode(BASE64DecoderStream.java:143) at com.sun.mail.util.BASE64DecoderStream.read(BASE64DecoderStream.java:54) at se.illuminet.httpd.mail.MailXMLService.serviceXml(MailXMLService.java:361) This occurs in booth javamail 1.2 and 1.3(.1) using dovecot. Of course this unfriendly/unhandled response is a problem with javamail while biting the dust. Further analysis points to that the reading works OK up until 2^16 bytes, so it fails either in reading the tail of the attachment or resuming after the first buffered data is consumed. I tried the BODYSTRCUTURE-patch (booth #1 and then #2), but it didn't help. Now I am fresh out of ideas. The java-bug has a three week delay to surface on "bug-parade". But I still have to explain why it works in UW/Cyrus and not with dovecot. Next step would be to add trace-lines in dovecot. Any ideas? /Jonas

[Dovecot] pop3s in Outlook

Hi, I'm using Dovecot for pop3-ssl. Unofortunatelly, most of my users are using MS Outlook. I want them to be able to remove standard mesage: "The certificat is not signed by...", but I don't know how :-( In the dialog isn't a button "Trust this certificate forever"... Is there anybody, who know, how to solve this? Many thanks.

[Dovecot] Handling of X-Status flags
by Bernard Blackham 29 Sep '03

29 Sep '03

Hi all, I've done a bit of searching and haven't seen anybody else coming across this problem yet: I noticed that Dovecot uses the opposite flags for marking messages as deleted and draft to most other MUAs I've seen or used: With PINE, mutt and uw-imapd at least, messages are marked with X-Status 'D' for Deleted, and 'T' for drafT. Dovecot reverses this behaviour, using 'D' for Draft, and 'T' for Trashed. Was there any reason behind this? Or have I gone loopy? At our site, we have users reading mail with a mix of PINE locally, and through dovecot via WebMail and there seems to arise a bit of confusion between the two flags. Attached is a patch that reverses this behaviour (prepared against 0.99.10 but applies with a little fuzz to cvs). I'd like to hear people's comments on the issue... is it just me? :) Thanks, Bernard. -- Bernard Blackham bernard at blackham dot com dot au

[Dovecot] Odd problem with dovecot segfaulting
by Tim Miller 29 Sep '03

29 Sep '03

Hi All, I installed dovecot on one of my servers the other day, and I want to use it in a vhosting environment. To this end, I have set it up to use password file authentication with a passwd file specified by me. This file will contain both system users and virtual accounts. To test it, I set up two accounts in the dovecot passwd file. One is a system user, I give his home dir in the correct field, along with the MD5 hash of his password in its field, and everything seems to work OK (he can login, read mail out of /var/spool/mail/user etc.). The seconmd account is a vhosted account, and I set the uid and gid to that under which the vhosting account exists. I did not set a home dir, but I set a mail dir in /var/spool/vmail/imap/vhost/user, and made this dir group writeable by dovecot. The user can login, but immediately upon authentication, dovecot segfaults (the log reports an "Internal login failure" and the authentication process is killed with signal 11, i.e. a segfault). Has anyone encountered this before? Is this even the right way to set up vhosting (I don't want to go with LDAP or SQL authentication right at the moment, but I may move to that later on)? Are there any things I should look for (this is probably due to something I've done wrong) or make dovecot be a bit more verbose in reporting errors to its log? Thanks in advance for any help. From what I've seen so far, dovecot looks like an excellent product. Best, Tim Miller

UW and Cyrus-ditto works, while when I try to read attachments (base64), I get slapped in the face with this: java.lang.NullPointerException at com.sun.mail.iap.Response.parse(Response.java:99) at com.sun.mail.iap.Response.<init>(Response.java:68) at com.sun.mail.imap.protocol.IMAPResponse.<init>(IMAPResponse.java:31) at com.sun.mail.imap.protocol.IMAPResponse.readResponse(IMAPResponse.java:105) at com.sun.mail.imap.protocol.IMAPProtocol.readResponse(IMAPProtocol.java:153) at com.sun.mail.iap.Protocol.command(Protocol.java:215) at com.sun.mail.imap.protocol.IMAPProtocol.fetch(IMAPProtocol.java:882) at com.sun.mail.imap.protocol.IMAPProtocol.fetch(IMAPProtocol.java:874) at com.sun.mail.imap.protocol.IMAPProtocol.fetchBody(IMAPProtocol.java:677) at com.sun.mail.imap.IMAPInputStream.fill(IMAPInputStream.java:74) at com.sun.mail.imap.IMAPInputStream.read(IMAPInputStream.java:105) at com.sun.mail.util.BASE64DecoderStream.decode(BASE64DecoderStream.java:143) at com.sun.mail.util.BASE64DecoderStream.read(BASE64DecoderStream.java:54) at se.illuminet.httpd.mail.MailXMLService.serviceXml(MailXMLService.java:361) This occurs in booth javamail 1.2 and 1.3(.1) using dovecot. Of course this unfriendly/unhandled response is a problem with javamail while it bites the dust. Further analysis points to that the reading works OK up until 2^16 bytes, so it fails either in reading the tail of the attachment or resuming after the first buffered data is consumed. I tried the BODYSTRCUTURE-patch (booth #1 and then #2), but it didn't help. Now I am fresh out of ideas. The java-bug has a three week delay to surface on "bug-parade". But I still have to explain why it works in UW/Cyrus and not with dovecot. Next step would be to add trace-lines in dovecot. Any ideas? /Jonas

[Dovecot] Multiple instances of .customflags staying open
by Ron 25 Sep '03

25 Sep '03

# cat /proc/version Linux version 2.4.20-18.9 (bhcompile(a)daffy.perf.redhat.com) (gcc version 3.2.2 20030222 (Red Hat Linux 3.2.2-5)) #1 Thu May 29 07:09:43 EDT 2003 # dovecot --version 0.99.10 I've just recently noticed a serious problem with my system. After about an hour or so I get errors in /var/log/maillog such as this; Sep 21 06:40:16 the-system imap(ray): opendir() failed with file \ \/home/ray/Maildir//new: Too many open files I investigated with 'lsof' and found that many copies of '.customflags' were open for each and every folder. ie; Each folder's '.customflags' file was open 15 times! I suspect that postfix is not able to store newly collected email while this is occuring, therefore I am likely losing messages. I've tried with multiple mail clients (Sylpheed & Evolution) and multiple users, always with the same result. Further investigation indicates that each time the client scans for new mail another instance of each and every '.customflags' is opened. As I have the client set for checking at five minute intervals then it was probably 75 minutes until the client barfed. Less, if I manualy scan for new mail a few times. If I shutdown the client and restart it then everything is fine for about an hour. Running 'lsof /home/ray/Maildir/.customflags' on the server I can see the list of files increasing each time the client checks for new mail. Any help would be appreciated!

I have my server and workstation set to GMT+3 and copying message from Dovecot to OE6 local folder and back keeps the message date the same. Or actually it looks like IMAP -> local folder copies using the message's Date field rather than IMAP's INTERNALDATE which Received-field shows. I'm not sure if this could be Dovecot's or OE6's fault ..

[Dovecot] dovecot IMAP misserving problem?
by Warren Togami 23 Sep '03

23 Sep '03

http://togami.com/~warren/archive/2003/evolution-1.4.4-crash.mbox I suspect that dovecot-0.99.10 is misserving this message in some way that is confusing some IMAP clients. This behavior causes evolution-1.4.4 to segfault, and squirrelmail-1.4.1 to be unable to read the message. The same message served by uw-imapd works works fine in both evolution and squirrelmail. https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=104288 Red Hat Bugzilla dovecot report https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=104289 Red Hat Bugzilla evolution segfault report http://bugzilla.ximian.com/show_bug.cgi?id=48418 Ximian evolution segfault report

[Dovecot] feature request: maildirquota
by Eero Volotinen 21 Sep '03

21 Sep '03

Hope maildirquota++ is soon supported, without it, dovecot is useless in my use (mail hosting with maildirquotas). Also QUOTA cabability in dovecot is needed to get to use my webmail plugins that use a001 CAPABILITY to get quota support. Courier imapd supports this. --snippet from quota usage plugin to squirrelmail-- function sqimap_get_quota ($imap_stream, $mailbox) { if (check_quota_capability($imap_stream, "QUOTA")) { fputs ($imap_stream, "a001 GETQUOTAROOT \"$mailbox\"\r\n"); $read_ary = sqimap_read_data ($imap_stream, 'a001', true, $result, $message); for ($i = 0; $i < count($read_ary); $i++) { if (ereg("STORAGE", $read_ary[$i])) { $tempusage = ereg_replace("^.*[(]STORAGE +(.*)[)].*$", "\\1", $read_ary[$i]); $usagearray = explode(" ", $tempusage); return $usagearray[0].":".$usagearray[1]; } } } return "NOQUOTA"; } function check_quota_capability($imap_stream, $capability) { global $imap_general_debug; fputs ($imap_stream, "a001 CAPABILITY\r\n"); $read_ary = sqimap_read_data($imap_stream, 'a001', true, $a, $b); for($i = 0; $i < count($read_ary); $i++) { if (ereg("QUOTA", $read_ary[$i])) return TRUE; } return false; } -- end snippet-- -- Eero

[Dovecot] convert wu-imap Maildir format to dovecot
by Alin Osan 21 Sep '03

21 Sep '03

Hello, I intend to migrate a mail server with Maildir from wu-imap to dovecot imap. Using horde/IMP, users can not access their imap forders, as wu-imap created Mail directory that holds all created folders. Dovecot could not detect the mail directory so I had to put default_mail_env = ~/Maildir in dovecot.conf. Before I begin to read the source-code of dovecot or try to migrate the the mailboxes using a shell script, is there any way I can make dovecot read the wu-imap folders format? Please suggest any solution that you find viable. Thank you. -- -- We are what we repeatedly do. Excellence, then, is not an act, but a habit. -- Alin Osan

[Dovecot] namespaces
by Brian Marcotte 21 Sep '03

21 Sep '03

I'm trying to use the namespaces feature to set up dovecot to look just like our existing Courier IMAP server, and our previous Cyrus server. That is, all folders are subfolders of INBOX, and the hierachy separator is ".". I put this in the configuration file: namespace private { separator = . prefix = INBOX. location = maildir:~/.maildir } This makes subfolders work correctly, but it can't find the INBOX: x1 select INBOX x1 NO Unknown namespace. Also, I don't really want to specify the location here. I want to use the userdb settings (I'm using password-file). Is there a way to make it use my setting in the userdb/password-file? Also, I'm not sure if it actually matters, but when selecting a folder, the number of RECENT messages is always the same as the number of messages which EXISTS: x2 select INBOX.Tech * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 70 EXISTS * 70 RECENT * OK [UNSEEN 69] First unseen. * OK [UIDVALIDITY 1057356619] UIDs valid * OK [UIDNEXT 181] Predicted next UID x2 OK [READ-WRITE] Select completed. I'm afraid some clients may use this information for something, and display incorrect information to the user. Thanks! -- - Brian

[Dovecot] Feature question/request
by Dan Sully 20 Sep '03

20 Sep '03

So I have a bunch of users who are roaming - IE no static IP address from all over the internet. Some of them are able to use SMTP-AUTH which is great, but for those that can't, a pop before smtp solution is in place using relay-ctrl-age & cdb files via qmail. Would it be desirable to have this feature in dovecot? I'd really like to ditch qmail-pop3d, etc. vpopmail has a open_smtp_relay() when using vchkpw directly. -D -- <iNoah> I won't be satisfied until I have a rectally-insertable laptop

[Dovecot] Multiple auth checkers
by Dan Sully 18 Sep '03

18 Sep '03

I noticed this is in the TODO: - support for multiple auth checkers. passdb+userdb should be tied together. auth process configurations really should be used for this.. and is functionality that I really would like, as I have local users (passwd+shadow) and vpopmail users. In -test7's dovecot-example.conf, there is a different format for "blocking" multiple auth types, and I created a conf as such: auth default { mechanisms = plain userdb = passwd passdb = shadow user = root count = 2 } auth vpopmail { mechanisms = plain userdb = vpopmail passdb = vpopmail user = vpopmail count = 2 } Password authentication still works fine, but I can't find a way to get it to fallback to using the vpopmail auth. Is this simply not working yet? Timo - what part of the code needs this update? Thanks. -D -- Change? We fear change.

[Dovecot] Unable to access the mailbox or folders !!

Hi, Thanx a lot for your reply. But my log file(its /var/log/dovecot) doesnt have any information other than the following line for example, imap-login: Sep 16 10:31:50 Info: Login: usr1 [127.0.0.1] After this when I give select command or anything like that, its not logged(I dont know also, how to enable maximum debug information, I checked the docs and all) Again, let me tell you that I suspect there is something wrong with the mail environment setting. its as follows default_mail_env = maildir:/var/spool/mail/%u/Maildir and when i give some nonexisting location ( eg; /var/blah/blah) also, I get the SAME ERROR. Here is a sample telnet session Trying 127.0.0.1... Connected to localhost.localdomain (127.0.0.1). Escape character is '^]'. * OK dovecot ready. a01 login usr1 XXXXXXXXX a01 OK Logged in. a02 select inbox a02 NO Please tell me if you would like to have any other info.

[Dovecot] Locking foolishness
by Ian Marlier 16 Sep '03

16 Sep '03

I'm working on getting Dovecot set up on my school's mailserver, as an IMAP and POP server. Everything is going well, move over to maildir went well, and all that... The catch: When I coverted from mbox to maildir (as part of this whole process), I put the Maildir folders under user home dirs -- and the home dirs are mounted via NFS from a server. This is for reasons of space as well as simply seeming to make sense. Now I get errors in my mail.log which read: imap-login: Sep 16 00:16:24 dovecot:Info: Login: marlier [209.6.159.188] imap(marlier): Sep 16 00:16:28 dovecot:Error: file_wait_lock() failed with index file /Network/Servers/network.uphamscornercs.net/Users/marlier/Maildir/.INBOX/.im ap.index: Invalid argument It looks to me like it's a file locking problem...any thoughts on how to get around it? I've already tried the dotlock mechanism alone...without success... More information available upon request... - Ian

[Dovecot] Locking foolishness - Better info
by Ian Marlier 16 Sep '03

16 Sep '03

I realized that my last message about locking gave bad information -- or rather, very little information. Here's my setup: - Home directories and user login information are located on an Xserve running Mac OS X 10.2.6. Home directories are split between 2 different directories -- /Users and /Students. Home dirs are exported via NFS to the mail server. User login info is shared via LDAP to the mail server and to Windows machines in classrooms. - The mail server is an old beige G3 running Debian Woody (linux 2.4.20) kernel. It's completely up-to-date. Homedirs are mounted at /Network/Servers/network.uphamscornercs.net/Users and /Network/Servers/network.uphamscornercs.net/Students, in keeping with the OS X Server userdir name scheme. The only user with a shell on the server is root, other than that all user information is pulled from LDAP using PAM. Postfix is setup to deliver mail to maildir:~/Maildir, and dovecot is set to read mail from the same directory. This is working without any problem. - Clients Entourage works fine to access mailboxes -- it reads mail without a problem. However, it pops up an error message intermittently that reads "Mail could not be read: Internal Error [<datestamp>]". This message doesn't seem to interfere with reading mail, it's just an annoyance. Squirrelmail doesn't work to access mailboxes. It logs in fine, but gives the following error message in all windows that require mailbox access: "ERROR : Could not complete request. Query: <imap query string> Reason Given: Internal error [<datestamp>]" In both cases (Entourage and Squirrelmail), the Internal Error is accompanied by the following error message in the /var/log/mail.log file: "imap(marlier): Sep 16 08:40:45 dovecot:Error: /Network/Servers/network.uphamscornercs.net/Users/marlier/Maildir/.subscript ions failed with subscription file file_wait_lock(): Invalid argument" So, it looks to me like something isn't working with locking. I'm not sure whether the problem is with the NFS mount, or with dovecot, or with permissions, or something else, but I'd like to get it fixed. I love the server, and if I can get this licked I think I've got a long-term setup. Relevant sections of /usr/local/etc/dovecot.conf: -------- # Use mmap() instead of read() to read mail files. read() seems to be a bit # faster with my Linux/x86 and it's better with NFS, so that's the default. mail_read_mmaped = no # Copy mail to another folders using hard links. This is much faster than # actually copying the file. This is problematic only if something modifies # the mail in one folder but doesn't want it modified in the others. I don't # know any MUA which would modify mail files directly. IMAP protocol also # requires that the mails don't change, so it would be problematic in any case. # If you care about performance, enable it. maildir_copy_with_hardlinks = no # Check if mails' content has been changed by external programs. This slows # down things as extra stat() needs to be called for each file. If changes are # noticed, the message is treated as a new message, since IMAP protocol # specifies that existing message are immutable. maildir_check_content_changes = yes # Which locking methods to use for locking mbox. There's three available: # dotlock: Create <mailbox>.lock file. This is the oldest and most NFS-safe # solution. If you want to use /var/mail/ like directory, the users # will need write access to that directory. # fcntl : Use this if possible. Works with NFS too if lockd is used. # flock : May not exist in all systems. Doesn't work with NFS. # # You can use both fcntl and flock too; if you do the order they're declared # with is important to avoid deadlocks if other MTAs/MUAs are using both fcntl # and flock. Some operating systems don't allow using both of them # simultaneously, eg. BSDs. If dotlock is used, it's always created first. mbox_locks = dotlock # Should we create dotlock file even when we want only a read-lock? Setting # this to yes hurts the performance when the mailbox is accessed simultaneously # by multiple processes, but it's needed for reliable reading if no other # locking methods are available. mbox_read_dotlock = yes # Maximum time in seconds to wait for lock (all of them) before aborting. mbox_lock_timeout = 300 # If dotlock exists but the mailbox isn't modified in any way, override the # lock file after this many seconds. mbox_dotlock_change_timeout = 30 # umask to use for mail files and directories umask = 0077 # Drop all privileges before exec()ing the mail process. This is mostly # meant for debugging, otherwise you don't get core dumps. Note that setting # this to yes means that log file is opened as the logged in user, which # might not work. It could also be a small security risk if you use single UID # for multiple users, as the users could ptrace() each others processes then. mail_drop_priv_before_exec = no --------- Thanks in advance for any help you can give. - Ian

Hi all, I have installed dovecot on redhat linux with ldap backend. I can login using ldap account in to my webmail (squirrelmail) .But when I login to the webmail , I cant see any inbox or anything . Just some error messages like this , ERROR: ERROR : Connection dropped by imap-server. Query: LIST "" "Sent" ERROR : Could not complete request. Query: SELECT "INBOX" Reason Given: I tried to telnet to port 143. Its also similar case. It allows me to login but when I give "select" command , it gives error(in fact, "NO" and nothing else). Required info, OS - Redhat 8.0 dovecot - dovecot-0.99.10-2.dag.src.rpm ( --with-ldap --with-rawlog additionally) MTA - Exim 4.14 Webmail - Squirrelmail 1.4.1-2 Location of Maildir - /var/spool/mail/USERNAME/Maildir dovecot configuration has the following line, default_mail_env = maildir:/var/spool/mail/%u/Maildir Is there anything I am missing or doing wrong ? I am sorry if this is a silly question. But I am a newbie to dovecot and did a lot of google search for this error or even additional documentation for dovecot without any success. Any suggestion or advice would be highly appreciated. Regards, Nasirudheen __________________________________ Do you Yahoo!? Yahoo!
