[Dovecot] Missing Mailboxes
by Jim 25 May '06

25 May '06

I upgraded from Fedora 4 to 5, which took me from dovecot .99 to 1.x. When I started up Thunderbird, I could not see any mailboxes other than Inbox. I am using Maildir with postfix. I re-installed .99, and all the mailboxes are back. I looked at the wiki on Missing Mailboxes, but I am not sure what I have to fix, and I do not really want to re-install the 1.x version and mess around, as I will mess up a number of other people. Clearly, I am not an expert, so if anyone can can help, I will be most appreciative! Jim

[Dovecot] Bug / Problem - Dovecot and Thunderbird
by wc_fbsd＠xxiii.com 25 May '06

25 May '06

Greetings, I've been running Dovecot for a couple years now. Currently 1.0.b8 on FreeBSD i386. I just switched to Mozilla Thunderbird 1.5.0.2 (windows) for an IMAP client, and am having some problems that appear to be at least partially attributable to Dovecot. After configuring the IMAP account, TB fetched the list of folders on the server, but was displaying several folders that had been deleted from the server months ago. When I tried to access or delete the folders from TB, it produced an error message (imap command failed, or something similar.) Some other folders had been moved from the root to sub-folders -- they still showed in the root, but not the sub-folder, thus were inaccessible. I looked all through the client's config files, but couldn't find any reference to them. From a shell on the server, I also verified they did not exist. I discovered they were still referenced in the .subscribe file, and had index files in .imap on the server. I deleted those, restarted the server processes, and refreshed the folders in TB, and the problem was resolved. But required manual intervention on the server. Not sure if this is a bug or just client issue, but since those files are maintained by Dovecot, I'm inclined to say "bug". Disclaimer: I know next to nothing about the internals of IMAP! -Thanks, Wayne

[Dovecot] LDAP, sieve, and virtual users
by Tracy R Reed 25 May '06

25 May '06

This seems to be a common topic but I haven't seen anyone ask this exact question and get a decent answer: I use virtual mailboxes with all of the db's in LDAP. Last night I upgraded to the latest CVS version of dovecot and dovecot-lda and got global sieve filtering working by setting the global_script_path to a sieve like /home/vmail/mydomain/sieve and it works great. Now I need to figure out how to get per-user sieve filtering to work. I googled on this and found: http://www.dovecot.org/list/dovecot/2005-August/008568.html How do I tell dovecot where the "virtual home directory" is? Yes, I could use /home/vmail/mydomain/user as my virtual home directory (that is where I originally tried to put .dovecot.sieve but it did not seem to work) but I don't see how I can tell dovecot about it. I see that in deliver.c #define SIEVE_SCRIPT_PATH "~/.dovecot.sieve" we hard code SIEVE_SCRIPT_PATH with the home dir location. Am I going to have to replace this with some code that generates an appropriate path for my system or is there a better way? And while I am here: Has any thought been given to being able to pull sieve scripts from LDAP? At the moment sieve really does not buy me much because the end users still do not have any way to edit their sieve files on the server (no shells and can't code sieve's language) but it would be nice if I could create a web interface somewhere which could generate basic filters from templates and store their sieve filters in LDAP so I didn't have to deal with somehow writing to files in their virtual home dirs on the mail server. I have found old conversations such as: http://www.mhonarc.org/archive/html/ietf-mta-filters/1999-06/msg00000.html but do not see where any standard way of doing this has come about. Or really even any implementations at all of sieve stored in LDAP.

[Dovecot] LDA Problem
by Alexander Dreweke 25 May '06

25 May '06

Hi I'm having a problem with dovecot deliver. I'm using a dovecot version 1.0.beta8. As I am using a chrooted (/var/spool/postfix) postfix (version: 2.2.10) with cyrus-sasl authentification (all working). Postfix config is changed according to the http://wiki.dovecot.org/LDA: main.cf: mailbox_command = dovecot master.cf: dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/deliver -d ${recipient} I have adopted the dovecot.conf also according to http://wiki.dovecot.org/LDA but changed the auth_socket_path to point into the chroot of postfix. I have attached my dovecot.conf at the end of this email. The mails that are sent to the machine are not delivered at all. In the mail-logfile I can see the following error message for each mail that can't be deliverd: postfix/pipe[21344]: BC254154E5BD: to=<root>, orig_to=<root>, relay=dovecot, delay=0, status=bounced (user unknown) I've already search the net but could not find any clue how to solve this. Can anyone give me a hint what to do? cu Alexander dovecot.conf: =========================================================== protocols = imap imaps listen = localhost ssl_listen = * first_valid_uid = 1000 first_valid_gid = 1000 mail_extra_groups = mail mail_save_crlf = no default_mail_env = maildir:/var/mail/%u protocol imap { } protocol lda { postmaster_address = postmaster(a)domain.com auth_socket_path = /var/spool/postfix/var/run/dovecot-auth-master } log_timestamp = "%Y-%m-%d %H:%M:%S " ssl_disable = no ssl_cert_file = /etc/ssl/certs/executor.pem ssl_key_file = /etc/ssl/private/executor.key ssl_cipher_list = HIGH:MEDIUM auth default { mechanisms = plain passdb pam { } userdb passwd { } user = root socket listen { master { path = /var/spool/postfix/var/run/dovecot-auth-master mode = 0660 user = dovecot group = mail } client { path = /var/spool/postfix/var/run/dovecot-auth-client mode = 0660 user = dovecot group = mail } } } } ===========================================================

[Dovecot] Client workaround?
by David King 24 May '06

24 May '06

I have a phone (LG CU320) with a built-in IMAP client. However, it has some issues. For one, the phone crashes if there are greater than some-as-of-yet-determined-number-of folders. That can't be worked around at the server, but this one can: After a long session of staring at tcpdump, it appears that when it logs in it does so like this: a001 LOGIN "username" myPassword This works unless one has funny characters in their password (which is usually the case). Why on earth it would put quotes around the username and NOT the password is beyond me (which is more likely to have special characters?) It does seem to check the CAPABILITY line to see what authentication is supported, because if I try it with a different (cyrus) server, instead of using LOGIN to authenticate, it uses AUTHENTICATE Dovecot presents that it supports AUTH=PLAIN, whereas Cyrus presents that it supports AUTH=PLAIN AUTH=LOGIN AUTH=CRAM-MD5 AUTH=GSSAPI. This is presumably because Dovecot prefers STARTTLS or simple IMAPS for authentication. So as I see it, getting this phone work with Dovecot and a password with special characters can take one of two forms (either of which I'll be happy to code): 1. Somehow getting Dovecot to look at the second token as if it *were* quoted. 2. Getting Dovecot to present and interpret AUTH=LOGIN (i. e. AUTHENTICATE), which appears to cause the phone to properly escape the password The first one really only fixes certain special characters, and leaves others still broken (like quotes themselves), and in fact violates IMAP4rev1. So I'd just make and run a local patch The second one fixes the problem more cleanly, and my code can be reused and submitted to the Dovecot commiters. So my question to anyone familiar with the codebase is, which of these options is more likely to work, and would the Dovecot team be interested in patches for either one?

But in my experience, it's bad practice, both in the enterprise and in the service provider world. When your box gets hit with a denial of service attack, or 500 users decide to copy the latest cool video to their home dir, and it's also your mail and web server, all of your services go to hell.

This is a very simple problem to fix, and doesn't require blocking port 22. Set up /etc/hosts.allow: sshd : 192.169.1.0/255.255.255.0 sshd-keygen-wrapper : 192.168.1.0/255.255.255.0 Set up /etc/hosts.deny: ALL: ALL:deny Tcpwrappers will now take care of you, and any DOS attacks you get will simply be dropped. > Do consider running your mail services off a machine that is not a Mac > OS X server.

While some of this statement may be accurate, there's a lot of FUD here too. Both OS X and OS X server use the same kernel, it is true. However, these operating systems are fast and reliable. We ran our mail server for a couple of years on OS X with exim and courier-imap, and the only reason we did stop and move to Linux is because we needed a bigger solution and intel-based hardware was cheaper than a bunch of XServes. And I will challenge your statement about high load. We have two web servers that average betwen 5 and 10 mbits of constant web load, running on OS X Server and XServes. The average load on these boxes is something like 0.20. Roger Weeks

[Dovecot] Busy, again
by Timo Sirainen 24 May '06

24 May '06

Just a note to people if you're wondering why I'm not replying to most of my mails: I'm trying to get into university to start stydying cellular biology (so I'm applying to biochemistry and biotechnology). Their entrance exams are next wednesday, so I'm trying to use most of my time left to study for them (and also do some work..). I don't know much about the subject, so I really need to study for them. :) Then again, if I don't pass, my fallback plan is to go in via computer science and try again next year. Hopefully they allow taking the same bio-classes even if it's not my major.

Hello I'm running dovecot v1.0.beta3 on a fedora 4 machine.

[Dovecot] Thunderbird 1.5 and messages with no Date: header
by grant beattie 24 May '06

24 May '06

hi, some of my Thunderbird users have a minor but annoying problem with messages that have no Date: header. these clients use BODY[HEADER.FIELDS (Date)] as the date for messages. when a message has no Date: header, they display the date as 01/01/1970 10:00:00 because Dovecot returns empty string. would it be possible for Dovecot to return INTERNALDATE instead, for messages that contain no Date: header? I know this is not *technically* correct, but it's a reasonable best-guess, and better than returning nothing. perhaps as a client-workaround? I vaguely recalled a previous message about this, but I couldn't find it today. grant.

[Dovecot] Shared folder (namespace) access hanging
by Jeff Turner 24 May '06

24 May '06

Hi, I'm using Dovecot 1.0-b8. We use a shared 'support' account for incoming support mail. For security reasons we want to instead have everyone with their own account, accessing a shared 'support' folder. So I've configured dovecot with a public 'Support' namespace: default_mail_env = maildir:/imap/mailboxes/%u namespace private { separator = / prefix = inbox = yes } namespace public { separator = / location = maildir:/imap/mailboxes/support:CONTROL=/imap/mailboxes/%u/shared-settings/support/control prefix = Support/ hidden = no } So now: - User 'support' logs in (this is the user whose folder is being shared).

User 'jturner' can view the folder contents, and a uidlist file for them appears: # cat /imap/mailboxes/jturner/shared-settings/support/control/.INBOX.test/dovecot-uidlist 1 1147758095 9 1 1147755677.P8078Q3M183587.redback.sydney.atlassian.com:2,RSace 2 1147755677.P8078Q2M183587.redback.sydney.atlassian.com:2,abcdf 3 1147755677.P8078Q1M183587.redback.sydney.atlassian.com:2,Sabcd 4 1147756077.P8078Q8.redback.sydney.atlassian.com:2,Sabcd 5 1147756440.P8461Q3M643698.redback.sydney.atlassian.com:2,Sa 6 1147756440.P8461Q2M643698.redback.sydney.atlassian.com:2,Sa 7 1147756440.P8461Q1M643698.redback.sydney.atlassian.com:2,Sa 8 1147756440.P8461Q0M643698.redback.sydney.atlassian.com:2,Sa Although the contents is the same (1-8), the UIDVALIDITY at the top is different to that for the 'support' user: # head -1 /imap/mailboxes/jturner/shared-settings/support/control/.INBOX.test/dovecot-uidlist 1 1147758095 9 # head -1 /imap/mailboxes/support/.INBOX.test/dovecot-uidlist 1 1147757548 9 and now if I log back in as 'support' and access the folder, dovecot complains: dovecot: May 16 15:47:05 Error: IMAP(support): Corrupted index cache file /imap/mailboxes/support/.INBOX.test/dovecot.index.cache: indexid changed Switching back and forth results in various errors: dovecot: May 16 15:48:04 Error: IMAP(support): Corrupted transaction log file /imap/mailboxes/support/.INBOX.test/dovecot.index.log: end_offset (656) > current sync_offset (512) dovecot: May 16 15:48:04 Error: IMAP(support): Corrupted transaction log file /imap/mailboxes/support/.INBOX.test/dovecot.index.log: invalid indexid (1147758095 != 1147757548) dovecot: May 16 15:48:04 Error: IMAP(support): Corrupted transaction log file /imap/mailboxes/support/.INBOX.test/dovecot.index.log: invalid new transaction log sequence (2 >= 2) dovecot: May 16 15:48:04 Error: IMAP(support): Lost transaction log file /imap/mailboxes/support/.INBOX.test/dovecot.index.log seq 1 ------------------------------ In the wild, I've seen frequent occurrences of this error, where dovecot seems to switch between the UIDVALIDITY of 'support' and a user's dovecot-uidlists: dovecot: May 16 13:56:28 Error: IMAP(jturner): Maildir /imap/mailboxes/support/.INBOX sync: UIDVALIDITY changed (1147751603 -> 1147686345) and here's it toggling back from 'support' to jturner's dovecot-uidlist uidvalidity: dovecot: May 16 14:16:04 Error: IMAP(support): Maildir /imap/mailboxes/support/.INBOX sync: UIDVALIDITY changed (1147752716 -> 1147751603) I've also seen plenty of processes being killed, seemingly at random, about 3 or 4 a minute: # cat /usr/local/logs/dovecot | grep killed.wit ... dovecot: May 16 12:00:16 Error: child 32706 (imap) killed with signal 6 dovecot: May 16 12:00:16 Error: child 32649 (imap) killed with signal 14 dovecot: May 16 12:00:45 Error: child 32412 (imap) killed with signal 6 dovecot: May 16 12:01:02 Error: child 32702 (imap) killed with signal 6 dovecot: May 16 12:01:02 Error: child 368 (imap) killed with signal 6 dovecot: May 16 12:01:02 Error: child 357 (imap) killed with signal 6 dovecot: May 16 12:01:16 Error: child 383 (imap) killed with signal 6 dovecot: May 16 12:02:26 Error: child 32297 (imap) killed with signal 6 ... So I'm confused. Am I doing something stupid? Why is there a common .cache file (it doesn't get created in the CONTROL dir), but not a common dovecot-uidlists? Is anyone actually *using* shared folders? :) Thanks, Jeff

[Dovecot] IMAP Folder Creation
by Zach Hobbs 23 May '06

23 May '06

I am using Maildir with dovecot 0.99.14-1 and postfix. My IMAP server was working where I could create a folder in Kmail or Thunderbird and specify wether the folder was to hold messages or folders. Then something changed, and I lost all my folders that contained sub-folders. And now I cannot create folders that contain subfolders (Kmail doesn't event give the option anymore). I can create folders and put messages in them, but I cannot create subfolders in the newly created folders. The Maildir is owned by the user logging in. Do I need to do anything with permissions, or are there settings to allow/disallow this? I've been reading through everything I could find with dovecot and folders in the message, and I can't come up with anything. Here's an example file structure (logging in as "zta-tech_zach"): Maildir# ls -lA -R .: total 32 drwx------ 2 zta-tech_zach web1 4096 2006-05-22 21:41 cur -rw------- 1 zta-tech_zach web1 5 2006-05-22 21:16 .customflags -rw------- 1 zta-tech_zach web1 52 2006-05-22 21:40 dovecot-uidlist drwx------ 2 zta-tech_zach web1 4096 2006-05-22 21:16 .INBOX drwx------ 2 zta-tech_zach web1 4096 2006-05-22 21:40 new -rw------- 1 zta-tech_zach web1 6 2006-05-22 21:41 .subscriptions drwx------ 2 zta-tech_zach web1 4096 2006-05-22 21:40 tmp drwx------ 5 zta-tech_zach web1 4096 2006-05-22 21:25 .Trash ./cur: total 20 -rw------- 1 zta-tech_zach web1 16591 2006-05-22 21:40 1148352021.3157_1.www.zta-tech.com:2,S ./.INBOX: total 24 -rw------- 1 zta-tech_zach web1 1608 2006-05-22 21:41 .imap.index -rw------- 1 zta-tech_zach web1 10264 2006-05-22 21:16 .imap.index.data -rw------- 1 zta-tech_zach web1 2576 2006-05-22 21:16 .imap.index.log -rw------- 1 zta-tech_zach web1 1560 2006-05-22 21:16 .imap.index.tree ./new: total 0 ./tmp: total 0 ./.Trash: total 40 drwx------ 2 zta-tech_zach web1 4096 2006-05-22 21:24 cur -rw------- 1 zta-tech_zach web1 5 2006-05-22 21:25 .customflags -rw------- 1 zta-tech_zach web1 1608 2006-05-22 21:24 .imap.index -rw------- 1 zta-tech_zach web1 10264 2006-05-22 21:25 .imap.index.data -rw------- 1 zta-tech_zach web1 2576 2006-05-22 21:25 .imap.index.log -rw------- 1 zta-tech_zach web1 1560 2006-05-22 21:25 .imap.index.tree drwx------ 2 zta-tech_zach web1 4096 2006-05-22 21:24 new drwx------ 2 zta-tech_zach web1 4096 2006-05-22 21:24 tmp ./.Trash/cur: total 0 ./.Trash/new: total 0 ./.Trash/tmp: total 0 Thanks, Zach

[Dovecot] Dovecot IMAP not putting size in maildir filenames
by Bill Boebel 23 May '06

23 May '06

I notice that when you move a message from one maildir folder to another, Dovecot drops the size information ("S=") from the filename. Dovecot also does not add the size info to filenames after it gets it via stat(). Shouldn't Dovecot add the size info to the filename so that "maildirsize" recalculations are fast? Bill

[Dovecot] two concurrent dovecots
by Alexey Koptsevich 20 May '06

20 May '06

Hello, Is it safe to have two concurrent dovecot processes to access the same maildir? I have a stock RHEL version (0.99.11) used by users, but I also want to test 1.0-beta together wth postfix for SASL. Is it safe to access the same maildir concurrently with both dovecots (say, the old one via webmail and the new one via remote client)? Thanks, Alex

[Dovecot] Dovecot/LDAP problem
by Burton Simmons 19 May '06

19 May '06

Dear Dovecot mailing list people - What I'm trying to do is use Postfix (with virtual users) and a POP3 server (we don't want IMAP - don't ask) to work against our new Active Directory servers that will be coming soon. Before we roll anything out we're testing it in the lab. Here's what we've got: x86 server running Red Hat Enterprise Linux 3 Postfix 2.0.16 Dovecot-1.0 Beta7 Windows 2003 server running Active Directory Windows XP client running Outlook Eventually, we'd like the clients to be joined to the AD domain and that's where we'll store ALL the user information. The email will come in on our postfix server (which uses virtual users) and the clients will check it passing their email username and domain password. The catch is that USERS CAN BE ANYWHERE IN THE DIRECTORY. (I apologize for the caps, I wanted to make sure that phrase wasn't glossed over.) So, for instance: > DC=local | >DC=domain | >OU=group1 | | | > CN=user1 | > CN=user2 | >OU=group2 | | | > CN=user3 | > CN=user4 | >OU=group3 | >CN=user5 The path to user1 is therefore CN=user1,OU=group1,DC=domain,DC=local (at least in the AD world.) The path to user3 is CN=user3,OU=group2,DC=domain,DC=local. So to search for users I would think (because this is how Postfix does it) that I could have the search base as DC=domain,DC=local and then have scope = subtree. IT DOESN'T WORK. (Again, caps used for emphasis only.) Here's the meat of the dovecot-ldap.conf file I'm using: hosts = 192.168.x.x dn = cn=Administrator,cn=Users,DC=domain,DC=local dnpass = xxxxx auth_bind = yes ldap_version = 3 base = DC=domain,DC=local scope = subtree user_attrs = sAMAccountName,mail,,,, user_filter = (&(objectClass=organizationalPerson)(sAMAccountName=%u)) pass_filter = (&(objectClass=organizationalPerson)(sAMAccountName=%u)) user_global_uid = 44 user_global_gid = 44 --- Interestingly, if I simply point the base to the actual user's container, it works just fine. The idea works from Postfix, but from dovecot it doesn't actually seem to search the tree. --- Here's some of the output from the log files. dovecot: May 17 15:35:52 Info: auth(default): client in: AUTH 1 PLAIN service=POP3 lip= 192.168.0.199 rip=192.168.0.195 resp=AGp1c2VyAHBhc3N3b3Jk dovecot: May 17 15:35:52 Info: auth(default): ldap(user1, 192.168.0.195): bind search: base=DC=LAB,DC=local filter=(&(objectClass=organizationalPerson)(sAMAccountName=user1)) dovecot: May 17 15:36:52 Info: pop3-login: Disconnected: Inactivity: method=PLAIN, rip= 192.168.90.195, lip=192.168.90.199 dovecot: May 17 15:37:52 Info: auth(default): client in: AUTH 1 PLAIN service=POP3 lip=192.168.0.199 rip=192.168.0.195 resp=AGp1c2VyAHBhc3N3b3Jk dovecot: May 17 15:37:52 Info: auth(default): ldap(user1,192.168.0.195): bind search: base=DC=domain,DC=local filter=(&(objectClass=organizationalPerson)(sAMAccountName=user1)) dovecot: May 17 15:37:54 Info: auth(default): client out: OK 1 user=user1 dovecot: May 17 15:37:54 Info: auth(default): client out: OK 1 user=user1 dovecot: May 17 15:37:54 Info: auth(default): master in: REQUEST 1 25233 1 dovecot: May 17 15:37:54 Info: auth(default): ldap(user1,192.168.0.195): base=DC=LAB,DC=local scope=subtree filter=(&(objectClass=organizationalPerson)(sAMAccountName=user1)) fields=sAMAccountName,mail,,,, dovecot: May 17 15:38:52 Info: pop3-login: Disconnected: Inactivity: user=<user1>, method=PLAIN, rip=192.168.0.195, lip=192.168.0.199 Can anybody offer any insight?

[Dovecot] configure change for 1.0.beta8
by Tomi Vainio 19 May '06

19 May '06

Hi, I'm trying to compile dovecot under Solaris 10 with native Mysql support. Couple changes are needed before configure can detect and compile mysql support. Native Solaris Mysql is installed under /usr/sfw directory. Configure can't find libraries and when these are found -R runtime path is needed for linking. Also if library name is given before library path it can't find it. These changes are needed for configure script line 29533 for i in /usr /usr/local /usr/local/mysql /usr/sfw; do line 29548 LIBS="$LIBS -L$MYSQL_LIBDIR -R$MYSQL_LIBDIR" line 29559 LIBS="$LIBS -lmysqlclient" line 29770 SQL_LIBS="$SQL_LIBS -L$MYSQL_LIBDIR -R$MYSQL_LIBDIR" line 29780 LIBS="$LIBS -lmysqlclient" Tomppa
