[Dovecot] problem getting mail from mbox
by Gavin Estey 16 Oct '03

16 Oct '03

I'm trying to set up dovecot and I'm running into a few problems. I just want to use IMAP for one user, everyone else gets POP3 from the existing (working server). $MAIL is set to /var/spool/mail/gavin_imap In my /var/spool/mail directory I now have a problem: -rw------- 1 gavin_im mail 1392 Oct 14 22:28 gavin_imap -rw------- 1 gavin_im popusers 0 Oct 14 21:54 gavin_imap When I try to get my mail, I guess it's checking the wrong file as I can't download anything. I also can't delete the file (which I find confusing as I am root): [root@chicken mail]# rm gavin_imap rm: cannot remove `gavin_imap': No such file or directory I actually have the same problem with the dovecot log file. I have this in my config: info_log_path = /tmp/dovecot -rw------- 1 root root 4436 Oct 14 22:40 dovecot [root@chicken tmp]# cat dovecot cat: dovecot: No such file or directory I don't get any obvious errors if I telnet in: [root@chicken tmp]# telnet localhost 143 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. * OK dovecot ready. 1 LOGIN gavin_imap <pass> 1 OK Logged in. 1 SELECT Inbox * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 0 EXISTS * 0 RECENT * OK [UIDVALIDITY 1066184985] UIDs valid * OK [UIDNEXT 1] Predicted next UID 1 OK [READ-WRITE] Select completed. 1 LOGOUT * BYE Logging out 1 OK Logout completed.

[Dovecot] exchange, dovecot, mutt, evolution
by Krammer Clemens 16 Oct '03

16 Oct '03

Dear all, When I "migrate" my outlook folders to imapd (dovecot) it works well from a Windoze perspective, but if I open a migrated folder via imap (mutt, evolution) a cannot see the Senders. If i open the folder locally via mutt, the Senders are displayed correctly. By examining one folder with vi I recognised that there are no valid From headers but Return-Paths. Is there a common way to see the senders when connecting with imap? Best Regards, Clemens

[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.

[Dovecot] Darwin Build (cvs)
by Jesse Peterson 09 Oct '03

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. Best Regards, Bert Koelewijn

[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...

[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

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

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

by Jonas Bosson 25 Sep '03

25 Sep '03

Dear folks, this might be a javamail-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 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.

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).

[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

[Dovecot] Setting up a local shared mailbox
by Peter Clark 14 Sep '03

14 Sep '03

One: I have never set up an IMAP server before, so I thought I would ask first before blindly stumbling around. The problem I am want to solve is this: my wife and I have a "joint" email account that we both want to access (we also have our own personal accounts, but that's beside the point.) I posed the question to my local LUG, and several suggested setting up a local IMAP server so that we can both access it through KMail. Would you concur? If so, is there a tutorial or something similar that gives instructions for setting up dovecot locally? As I said, I've never set up an IMAP server before, and I'm not really sure how to go about it. (I'm running Debian Sid, so the packages are already installed, but I don't know what additional steps need to be taken.) Thanks for your help, :Peter

[Dovecot] Patch for auto-creating home directories
by David S Madole 13 Sep '03

13 Sep '03

I've created a patch that adds a feature that is helpful to my setup. If 'parent_dir_umask' is set in the configuration file, any missing directories in the home directory path are created. The home directory itself is created according to the 'umask' setting, 'parent_dir_umask' is only used for intermediate directories that might need creating. This is useful to me, as I pull user information from a PostgreSQL database. This allows a new account to be created just by populating the database.

[Dovecot] Dovecot on Linux 2.6.0-test1-ac1

I've been using Dovecot on 2.6.0-test1 for quite awhile but today I jumped ahead to test5 and it broke in the way you described. http://dovecot.procontrol.fi/list/dovecot/2003-July/001943.html I used your workaround and now everyone is back in business. Thank you for the help! (I was sweating there for a bit.) --kyler

[Dovecot] Web administration tool
by Timo Sirainen 10 Sep '03

10 Sep '03

Any suggestions for a small web based tool to manage virtual domains/users? I tried to look but didn't really find anything that didn't seem to be tightly integrated with Courier or Cyrus, and I'd rather not spend time writing yet another one of those. I would be using Postfix and Squirrelmail with LDAP or PostgreSQL. On a somewhat related thought, I've been thinking about writing some kind of performance and statistics tool which would at least show the users who are logged in and how much CPU, memory and disk I/O they're eating so that you could see what's happening when load is too high. From Dovecot side that'd be done using a plugin. I'm not sure what the client side would be.. HTML might not be enough. Java maybe. Would Flash be too evil? :)

I have trouble to get my INBOX-mbox to work properly. I have set the default_mail_env, to this..

[Dovecot] still getting weird .{inbox} folder creations with latest -test7
by Charlie Allom 06 Sep '03

06 Sep '03

Hi, I am still getting strange creation and mailbox lookups from 0.99.11-test7. dovecot creates in ~/Maildir/ .INBOX/ .imap.index .imap.index.cache .imap.index.log .customflags dovecot-uidlist .INBOX seems to be a reference to ~/Maildir/{cur,new,tmp} yet I cannot get an IMAP client uo pick up my other maildir, located at ~/Maildir/mi/{cur,new,tmp}. In Apple's Mail.app, it picks up a file called ~/Maildir/.procmaillog as if it were a maildir directory! This is with the Mail.app preference for "IMAP Path Prefix" set to null. mutt just seems plain confused. I have these settings: # imap styleee set folder=imap://yeled@lazy.spodder.com/ set mbox=imap://yeled@lazy.spodder.com/mbox set record=imap://yeled@lazy.spodder.com/sent set postponed=imap://yeled@lazy.spodder.com/postponed set spoolfile=imap://yeled@lazy.spodder.com/ set certificate_file=~/.mutt/certificates set mail_check=10 set timeout=10 set imap_home_namespace="" set imap_pass="foo" I have included the tcpflow files to show what the clients are doing.. Is it normal to search for folders starting with "." ? Why won't it just pick up my normally nested maildir folders? C. -- charlie(a)rubberduck.com - http://rubberduck.com/~yeled/

[Dovecot] dovecot, vpopmail and djb's tcpserver
by Lasse Danielsen 06 Sep '03

06 Sep '03

Hello! I've tried to set up dovecot in conjuction with vpopmail, and running it under djb's tcpserver instead of (x)inetd. Btw - there was no reference to setting dovecot up using (x)inetd either in the manuals/faqs i read, though I didn't search all that hard. Anyway, back to my Q: vpopmail uses vchkpw as an authentication mechanism, and with tcpserver I can do relaycontrol (based on vchkpw) with roaming users. Is there anyone who have tried this, and succeeded? Right now I use two imap services to accomplish this (bincimap has support for vchkpw). Thank you for any response. - Lasse Danielsen Never argue with an idiot. He'll drag you down to his level, then beat you with experience.

[Dovecot] pine, INBOX, and dovecot
by Jethro R Binks 04 Sep '03

04 Sep '03

Hi all, I've been experimenting with Dovecot; tests with Maildir seemed to work fine. However, now I'm trying with mbox folders, and I'm having a problem where I do not get an INBOX listed using pine. Outlook Express and IMP show it fine. I snooped part of the session, which appears to go like this (it is slightly garbled, sorry -- I couldn't get rawlog to work by creating dovecot.rawlog in the mail home directory): 00000002 CAPABILITY\r\n * CAPABILITY IMAP4rev1 SORT THREAD=REFERENCES MULTIAPPEND UN 00000003 LIST "" %\r\n" * LIST (\NoInferiors) "/" INBOX * LIST (\NoInferiors \UnMarked) "/" "test" * LIST (\NoInferiors \UnMarked) ""/" "Sent Items" * LIST (\NoInferiors \UnMarked) "/" "Drafts" 0000000a OK List .completed.. Pine just displays "test", "Sent Items", and "Drafts". OE happily downloads mail from the inbox I put there, and IMP can see it and read it. Perhaps there is something there that IMAP protocol people might see. Or else, perhaps there is a known reason why pine does this? Any clues would be appreciated - I browsed the list archives but couldn't spot anything very relevant. Pine version is very recent - I updated today to 4.56. Incidentally, is mbox support still broken in the CVS version? Is there an expected timescale for the next release, preferably with mbox fixed again?! Thanks for any advice.

hello, this may be a very stupid question but how do i load a config file? i didn't find the docs part which explains how to start the imapserver at all. i have put this in my xinetd.conf: service imap { disable = no socket_type = stream protocol = tcp wait = no user = root server = /usr/local/dovecot/imap flags = IPv4 } and the server is running, but thats all. as u can see i have installed the server in /usr/local/dovecot and i have put the config file in /etc, /usr/local/etc and the programmdir itself - nothing worked. what commands must i write in the xinetd.conf to get the server running ? thanks -- E-Mail by http://www.jesus.ch/ and http://www.livenet.ch/ News, Magazin, Events, Forum, Chat, Free E-Mail, Dialin, Jobs, Top-Newsletter

[Dovecot] observations about delays
by Eric S. Johansson 01 Sep '03

01 Sep '03

I've tried two imap clients (mahogany and Mozilla) and they both have strange delays and weird failures. As a reminder, I am using mbox format mailboxes on the server and client side filtering of messages from the inbox. In both cases when the client fetches messages from the inbox and starts redistributing them, CPU utilization on the imap server goes to around 40 percent for Mozilla and around 90 percent for mahogany. There are long delays on the order of two minutes when filtering messages. or 30 to 50 seconds when opening a mailbox. Other than the performance problems, Mozilla is relatively well-behaved. Mahogany on the other hand is a bit more rough and (not) ready. It uses c-client for its imap code and during the filter driven message redistribution process, it all of a sudden started started complaining about unexpected EOF and I found one corrupted message: on 31/8/03 7:36 pm, Morten Christensen at ipcop-d(a)indbakke.dk wrote: >> These bugs might keep many people from trying a new alpha with >> interesting improvements. >> >> A more detailed help for fixing them after install is needed.

[Dovecot] Crash when searching messages
by Nicolas STRANSKY 01 Sep '03

01 Sep '03

Hi, I've been encountering a crash when trying to use the "Search messages" function with mozilla on a newly indexed/subscribed mailbox. I tryed to search something in "To or CC" and got the following : Sep 1 09:07:13 aster imap(nico): file message-address.c: line 255 (message_address_write): assertion failed: (addr->domain != NULL) Sep 1 09:07:13 aster dovecot: child 15674 (imap) killed with signal 6 In addition, mozilla gives the following message : "Server mail.neo-lan.net has disconnected. The server may have gone down or there may be a network problem" and the search fails. But there was no problem when doing other searches. After trying several different types of searches, the initial one (on TO or CC) worked fine, but the crash is reproducible on an other newly subscribed mbox. -- Nico Si cela fonctionne, c'est obsolète.

[Dovecot] conversion to maildir
by Eric S. Johansson 30 Aug '03

30 Aug '03

is really a royal pain in the butt. most of the conversion tools only do a partial job. mb2md seems to be the best but it does not convert the from line correctly unless you are using exim for an MTA. It also does not get the file status right so everything is written to the new maildir directory. something else that makes the process painful is when you have folders containing mailboxes. And the process is *slow* when you have 2 GB of mail (yes, I will be deleting some soon). looks like I will be debugging and rewrapping this package real soon now.. to relate this to dovecot: this is probably not the job of the imap server but it would be real nice to be able to fit in some sort of a plug-in that could automatically do the conversion on a mailbox as it is opened. it would make migrations trivial easy. give me the ability to use python for plug-ins and I will write such a tool. ---eric

[Dovecot] converting from courier-imap
by Emily 30 Aug '03

30 Aug '03

Hello. I apologize if there is a simple answer to this question, but I haven't been able to figure it out. Our people use various clients (pine 4.50 with maildir patch, eudora, messenger, outlook, squirrelmail), and all of them work with courier-imap. But I've become very interested in dovecot after reading about it, so I'm trying it out on another server. The results are mixed. Strangely enough, squirrelmail 1.4.1 works wonderfully. For some reason, it duplicates Sent, Drafts, and Trash, but I deleted the duplicates and it was fine. Mozilla messenger is also fine, but with the same duplication of those special folders. Everything seems nice and fast. But some of our users still cling to pine, which works with courier-imap using these three lines in .pinerc: inbox-path={our.server.edu/ssl/novalidate-cert/user=emily}INBOX default-fcc={our.server.edu/ssl/novalidate-cert/user=emily}INBOX.Sent folder-collections="IMAP Folders" {our.server.edu/user=emily/ssl/novalidate-cert}INBOX.[] On the test server I'm using dovecot-0.99.10 compiled against openssl-0.9.7b in Redhat 9. This pine configuration worked in courier, but when I try pine with dovecot, I can't see any folders under "Folder Collection" other than those special three (Drafts, Sent, Trash). I'm sure there's just something I'm doing wrong, but I couldn't find anything in the dovecot list archives. I would appreciate any advice on what I'm doing wrong in getting pine to see the whole collection. Thanks, -- Emily

[Dovecot] No localhost after reboot
by Bob Hall 30 Aug '03

Rebooted the server box today. Now Dovecot doesn't listen at localhost. It does listen at the LAN interface, so it is perfectly usable, but... Does anyone have any idea why it has stopped listening at localhost? Bob Hall

[Dovecot] Postgresql and Dovecot
by Michael Ducy 29 Aug '03

29 Aug '03

I am having some issues getting dovecot to work with postgres. Dovecot starts up and runs fine without using postgres (ie passwd and pam). There is nothing in /var/log/messages other than: Aug 28 12:44:05 mail dovecot: dovecot startup succeeded Then ps -A shows no running dovecot processes (or the imap-login or pop-login). I have tried with both the RPMs that are on the download page and buidling it myself on 2 different boxes (yes I configured with --with-pgsql - Red Hat 7.3 and Red Hat 9.0). Any suggestions would be appreciated as this is the only imap/pop server with pgsql support and flatfile support I can find. Michael

[Dovecot] better body and text search?
by Mark Anderson 29 Aug '03

29 Aug '03

(this is a resend, sorry if duplicate but my first post didn't get through). I was wondering what plans dovecot has for text and body search? This is one of those issues that *no* imap implementation ever seems to document :(. Not cyrus, courier, bincimap, or dovecot.... i speed-read some of the sources and found src/lib-mail/message-body-search.c After a quick scan, it seems: - it uses no text index at all, but does a linear search over the folder. - it searches only messages with content-type starting with "text/" or "message/" - it does no special parsing of "text/html", so tags and attributes would match - it appears to exclude any mime messages, since it skips "multipart/mixed" for example. - it does deal with content encoding and charset. There is a lucene-based text indexing utility for IMAP stores here: http://www.tropo.com/techno/java/lucene/imap.html But ideally there would be pluggable text indexing builtin.... -mda

[Dovecot] Custom flags.
by Maheshkumar Sabhnani 29 Aug '03

29 Aug '03

How do I define custom flags? What are added features of IMAP apart from Online access and Hierarchy folders. I created a new folder and copied couple of messages from incoming file. Where is this new folder created? Also Microsoft Outlook still shows the messages in incoming as deleted. How do I refresh list to permanently delete the messages that I have already transferred to a different folder. Mahesh

Hello, I am having problems with configuring dovecit. The imap directory was correctly made in ~/mail/.imap But I can't see any mail headers. My mbox path is ~/mail/incoming Currently I am trying to use "mbox:~/mail/:INBOX=~/mail/incoming" for configuration but it complains about missing value. Can someone send me more information on configuration directives especially mbox and INBOX. Early reply shall be appreciated. Regards, Mahesh

Not cyrus, courier, bincimap, or dovecot.... i speed-read some of the sources and found src/lib-mail/message-body-search.c After a quick scan, it seems: - it uses no text index at all, but does a linear search over the folder. - it searches only messages with content-type starting with "text/" or "message/" - it does no special parsing of "text/html", so tags and attributes would match - it appears to exclude any mime messages, since it skips "multipart/mixed" for example. - it does deal with content encoding and charset. There is a lucene-based text indexing utility for IMAP stores here: http://www.tropo.com/techno/java/lucene/imap.html But ideally there would be pluggable text indexing builtin.... -mda

[Dovecot] mail accounts for users without home dirs
by Gunter Ohrner 28 Aug '03

28 Aug '03

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi! I use dovecot on a machine where users without an existing home directory (Not my idea...) need to access their mailboxes. Unfortunately dovecot tries to chdir to the users home directory before allowing IMAP access - is there anything I can do about that besides creating a dummy-homedirectory for these users?

[Dovecot] 0.99.11-test6
by Timo Sirainen 28 Aug '03

28 Aug '03

http://dovecot.procontrol.fi/test/ I think I've fixed the problems that were corrupting indexes with the new code. It happened every time you had expunged some messages and new messages arrived. I think this release might actually work :) disable_plaintext_auth = yes will be default from now on. It allows plaintext authentication from localhost (127.*, ::1) however. I just figured out that the lockless cache file reading prevents me from fixing the mbox code to work the same way it used to. I'm not sure actually how this would be best fixed.. Problem is that headers in mails change and move the messages around in the mailbox, so I have to keep track of them. Previously I just updated the header size in index files.. but without read locks this can't be done safely. One possibility would be to parse the whole mbox file every time when the mailbox is opened (or when it needs to be read) and save the header sizes in memory. That'd make it slower than it is today though.. Or maybe it'd work if I just grabbed exclusive lock whenever reading header sizes. They could be then copied into memory to avoid locking more than once. But that still creates locking contention if lots of clients are reading the mailbox. Exactly in the situation where I'd mostly use mboxes.. I could also save it in .imap.index file which still currently uses read-locks. But I'd rather want to get rid of them in there too.

[Dovecot] IMAP error after login
by Nicolas STRANSKY 28 Aug '03

28 Aug '03

Hello, I'm having a slight problem with Dovecot (0.99.10-0.rc2, on Debian woody). When using mozilla 1.4, there is an error message from the mailer just after login, but nothing in dovecot logs. "Alert The current command did not succeed. The mail server responded: Error in IMAP command UID: Too long argument.." How could I fix this problem ? Thanks, -- Nico J'ai une panne de micro et les parasites me brouillent l'écoute

[Dovecot] Chrooting the Mail processes
by Bert Koelewijn 25 Aug '03

25 Aug '03

Hello! Could somebody give some feedback on this configuration: - OpenBSD box with local ssh users. - /home directory mounted with nosuid,noexec. - postfix dropping mail in /home/username/mail/INBOX, with the UID/GID of the user. - dovecot: valid_chroot_dirs = /home default_mail_env = mbox:/home/%u/mail/:INBOX=/home/%u/mail/INBOX Are there any obvious ways for a local user to help dovecot escape the chroot jail? How can I check that dovecot is REALLY using /home as chroot jail for the imap process? Thanks! Bert Koelewijn

[Dovecot] Docs on the wiki
by Bob Hall 25 Aug '03

25 Aug '03

I went to the Dove Wiki page and added a couple of docs. There's a DoveWikiMainPage link at the top of the first page now. Click on that and the next page has links to the two docs. Someone who knows more than I do about wiki formatting should make this look good. The two docs are for Dovecot/OpenLDAP installation. The first is detailed instructions and the second is a cheat sheet. You don't need to contact me if you find errors; just click "Edit this page" at the bottom. Anyone who wants to use parts of my docs to use in documenting other types of installation should feel free. There's no mention of copyright policy, but I assume everthing is GPL copyleft. Bob Hall

[Dovecot] Postfix and Maildirs
by Steve Sloan 24 Aug '03

24 Aug '03

Hope someone can help me with this as I am presently stuck I am setting up a new server with Dovecot 0.99.10, Redhat 9.0, Postfix, Amavisd-new and maildir's in the users home drive. I am using Netscape mail 7.1 as the main client to access the mail store via imap which works fine and various other imap clients can access the maildirs Ok as well. The problem is when Postfix delivers a message is insists on making a second Maildir directory in the user's home drive and put the message in there. The Maildir's are being created automatically ie. I didn't use maildirmake. Even if I delete one of the Maildir's it just gets recreated again. ie. this is the test user's home drive drwx------ 10 test2 test2 4096 Aug 23 20:53 Maildir drwx------ 6 test2 test2 4096 Aug 24 11:05 Maildir This is the Maildir that the clients are using and being accessed by Dovecot drwx------ 10 test2 test2 4096 Aug 23 20:53 . drwx------ 4 test2 test2 4096 Aug 24 11:05 .. drwx------ 2 test2 test2 4096 Aug 23 19:58 cur -rw------- 1 test2 test2 5 Aug 23 19:58 .customflags drwx------ 5 test2 test2 4096 Aug 23 19:59 .Drafts drwx------ 2 test2 test2 4096 Aug 23 19:58 .INBOX drwx------ 2 test2 test2 4096 Aug 23 19:58 new drwx------ 5 test2 test2 4096 Aug 23 20:15 .Sent -rw------- 1 test2 test2 29 Aug 23 20:13 .subscriptions drwx------ 5 test2 test2 4096 Aug 23 20:11 .test drwx------ 2 test2 test2 4096 Aug 23 19:58 tmp drwx------ 5 test2 test2 4096 Aug 23 20:11 .Trash and the other one which Postfix user's drwx------ 6 test2 test2 4096 Aug 24 11:05 . drwx------ 4 test2 test2 4096 Aug 24 11:05 .. drwx------ 2 test2 test2 4096 Aug 24 11:05 cur -rw------- 1 test2 test2 5 Aug 24 11:05 .customflags drwx------ 2 test2 test2 4096 Aug 24 11:05 .INBOX drwx------ 2 test2 test2 4096 Aug 24 11:05 new drwx------ 2 test2 test2 4096 Aug 24 11:05 tmp This one has no index files and looks just like a courier Maildir For Postfix main.cf I have set home_mailbox = Maildir/ and /etc/dovecot.conf default_mail_env = maildir:/home/%u/Maildir Hope this make sense to someone Steve -- _____________________________________________ LanSol Computers 283 Sir Donald Bradman Drv.

[Dovecot] Three oddities
by Bob Hall 24 Aug '03

24 Aug '03

FBSD 4.8, Dovecot-0.99.10 1) I have mail accounts for people who use Macs and Windows, so their mail is stored on a Unix box where they don't have accounts. When their mail comes in, it is stored in /var/mail/<accountname>. When I was setting this up, I used my own Unix account for testing, and that works fine. But for the other mail accounts, which don't correspond to Unix accounts, I want to give ownership of the /var/mail/* files to another account that doesn't have my privileges. However, no one can access their mail unless I own their files. As long as I own all the /var/mail/* files, everything works fine. But if I shift ownership to another account, users can log on to Dovecot but attempts to access an IMAP folder return an error. >From maillog: Aug 18 16:39:46 kongemord imap(philrodrigues): mkdir_parents(/var/mail/philrodri gues/.imap/INBOX) failed: Permission denied All files and directories in /var/mail/* are in the mail group. I tried adding dovecot to that group, but that didn't help. Since everyone can log on to Dovecot, but can't access their mail unless I own their files, I'm assuming that there's some simple ownership setting that I'm overlooking. But I haven't a clue what it is. Can someone tell me what I need to change? 2) The Macs have Eudora 4.2 installed, and the Win boxes have Eudora 5.1. The Macs can delete mail, put it in the trash, and empty the trash. The Win clients can mark mail deleted, but they can't remove it. The mail stays in the IMAP folder until the same user accesses their mail from a Mac and deletes it. If a user drags a message to another folder, a copy is created in the new folder but the old copy remains in the original folder. I'm not having this problem with Mutt, so it the problem seems to be specific to the Windows verson of Eudora. Is there a fix? 3) We're pulling our e-mail off our ISP's POP server and loading it into Dovecot to allow people to work with their mail from different machines. I'm using getmail to make the transfer. Is anyone else doing POP to IMAP, and how are they doing it? Any suggestions? TIA, Bob Hall

[Dovecot] user database clarification
by Jared 22 Aug '03

22 Aug '03

Hi, this question gets back to a thread I started back on July 8th. (gosh how time flies) I still am not clear on why PAM is not supported for the user database. I'm in an environment that has users both in local flat files (/etc/passwd and /etc/shadow) AND in an LDAP database. Is it possible for this set up to work with dovecot? (both local and ldap users have imap/pop?) I'd prefer to just have Dovecot use PAM for user db and the password database so that I can configure PAM to try both local users and LDAP users. Thanks a lot. -jared

[Dovecot] rawlog change suggestion

I find the separate .in and .out files rather difficult to work with. I think it would be more useful if the in/out traffic were interleaved with a prefix to indicate direction, and suffix to indicate continuation, as recordio (http://cr.yp.to/ucspi-tcp/recordio.html) does: <a0002 LIST "" "" >* LIST (\Noselect) ";" "" >a0002 OK List completed. <a0003 SELECT "INBOX" >* FLAGS (\Answered \Flagged \Deleted \Seen \Draft) >* OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags + >permitted. >* 18 EXISTS >* 0 RECENT >* OK [UNSEEN 18] First unseen. >* OK [UIDVALIDITY 1055795174] UIDs valid >* OK [UIDNEXT 6741] Predicted next UID >a0003 OK [READ-WRITE] Select completed. <a0004 STATUS "incoming.foo" (RECENT) >* STATUS "incoming.foo" (RECENT 397) >a0004 OK Status completed. <a0005 NOOP >a0005 OK NOOP completed.

[Dovecot] Mozilla dovecot interaction
by Eric S. Johansson 21 Aug '03

21 Aug '03

I think this is more a Mozilla bug but just a heads up the case other people complain. periodically, the Mozilla e-mail client refuses to delete messages. It shows up either as absolutely no action when you press the delete key/button or it shows activity but refuses to perform any other action in that mailbox. Sometimes if you switch to another mailbox and then come back to the mailbox you're deleting e-mail message from, the messages deleted when you re-enter the mailbox. I looked with ethereal and it looks like Mozilla is not sending any imap commands. Hence my assertion that it's a Mozilla problem. The only reason I mention it here is because something about dovecot seems to trigger the problem more quickly. I was seeing this kind of problem before but only after a week or two of uptime in the browser. Now I'm seeing it in just under a week (I think) I've only seen at once but I will keep track for future reference. I got to get me a new client... ---eric

[Dovecot] transitional weirdnesses
by Eric S. Johansson 20 Aug '03

20 Aug '03

1) not reproducible but when it occurred, its stuck: in the early transition to dovecot I would notice occasionally that messages would come up, I would delete them and then something would hang causing a major delay in the (Mozilla) e-mail client's response. When the system responded, I would notice that occasionally there would be an off by one offset between the index of messages and the message displayed. This error would persist until I killed off the index and the dovecot process. 2) very reproducible: after fetching messages from my inbox, there will be a long (30 sec.) delay. Dovecot demon is clearly busy doing something. I do have a large set of filter rules (approximately 150) sorting messages into different boxes. Is this a reason to switch to maildir? 3) just ended up with a message that displayed the entire header. Will look into this more but it's very strange. ---eric

[Dovecot] Squirrelmail and Dovecot folder namespace
by Warren Togami 19 Aug '03

19 Aug '03

I am currently using Squirrelmail and Dovecot with this setting: default_mail_env = mbox:%h/mail/:INBOX=%h/mail/INBOX It works well, however folder subscriptions in Squirrelmail annoyingly end up with "./" prefixes because Squirrelmail refuses to work without overriding the folder namespace. All of my other IMAP clients work fine without setting that option. Squirrelmail's default setting is this: $default_folder_prefix = './mail'; This setting breaks Squirrelmail: $default_folder_prefix = ''; This setting becomes default if you attempt to blank that user's preference: $default_folder_prefix = './'; The end result of this is duplicate entries in .subscriptions, one with "./" prefix and one without. Most IMAP clients handle this by showing all the folders again in a folder named ".", or Mozilla displays all folders twice. =( When I asked one of the squirrelmail developers, he said that this might be a dovecot specific problem. Any ideas? Warren Togami warren(a)togami.com

[Dovecot] Questions
by Alejandro Martinez 19 Aug '03

19 Aug '03

Hi, I'm still figthing with passwd-file, virtual users and permissions. I have created the directory /var/spool/virtual/test and inside I've done a "maildirmake Maildir". I have a couple of questions : I use the same passwd-file for auth_userdb and as auth_passdb. 1) What program can I use to create the userdb file ? What I do now is to use the htpasswd program and then I complete by hand the rest of the fields (uid:group:GECOS:home:shell) htpasswd userdb test password: xxx again: xxx And then vi userdb test@test.com:ssasZXc00P1H6:502:102::/var/spool/virtual/test/:/bin/false <--by hand. I think that if I want to offer virtual mail with imap is very tedious to complete user by user. (If this second question does not fall in this list, then don't answer it) 2) I know that postfix delivers in Maildir format, and when the user is a virtual user, I do the next Modify the virtual file ---> test(a)test.com test.test.com Modify the aliases file--> test.test.com: /var/spool/virtual/test/Maildir postmap hash:virtual postaliases hash:aliases postfix reload but when I do a "echo testing | sendmail test(a)test.com " I receive an error Aug 18 15:32:44 slk90 postfix/pickup[12208]: 95C3717D5C: uid=0 from=<root> Aug 18 15:32:44 slk90 postfix/cleanup[12252]: 95C3717D5C: message-id=<20030818183244.95C3717D5C(a)slk90.equital.lx> Aug 18 15:32:44 slk90 postfix/qmgr[12209]: 95C3717D5C: from=<root(a)slk90.equital.lx>, size=291, nrcpt=1 (queue active) Aug 18 15:32:44 slk90 postfix/local[12254]: 95C3717D5C: to=<test.prueba.com(a)slk90.equital.lx>, orig_to=<test(a)prueba.com>, relay=local, delay=0, status=bounced (cannot append message to destination file /var/spool/virtual/test/Maildir: cannot open file: Permission denied) I'm confused about permissions.

[Dovecot] more transitional joys

well, now that I have moved to dovecot, I'm not getting any spam... in fact, I'm not getting e-mail at all. default_mail_env =mbox:~/IMap2/:INBOX=/var/spool/mail/%u when I first tried to access my inbox, I was told I had permission problems: Aug 14 17:47:22 harvee imap(esj): open(/var/spool/mail/esj.lock) failed: Permission denied Aug 14 17:47:22 harvee imap(esj): file_lock_dotlock() failed with mbox file /var/spool/mail/esj: Permission denied so I changed permissions on /var/spool/mail to 777 as a temporary work around. no luck.
