[Dovecot] 2 problems
by Cor Bosman 10 Jun '04

10 Jun '04

Hi all, im testing dovecot as a replacement imap server and noticed 2 problems in 0.99.10.5. if you use dovecot/pop on an account who's quota is fully used, dovecot will ungracefully stop. This will only happen when the account is first accessed by dovecot (for instance, when offering IMAP to an existing userbase using dovecot, or when the index files have inadvertently been deleted). +OK dovecot ready. user scorpio +OK pass xxxxxxxx +OK Logged in. Connection closed by foreign host. The same goes for imap: * OK dovecot ready. . login "scorpio" "xxxxxxx" . OK Logged in. . select INBOX . NO Out of disk space This is a bit of a problem because one of the remedies of solving an out of disk space problem is deleting email, which you cant now. Cor

[Dovecot] mbox configuration
by Nina Pham 10 Jun '04

10 Jun '04

Hi, I change the dovecot.conf default_mail_env = mbox:/Mail/IMAP/%u/:INBOX=/var/mail/%u After I did the change, I restart dovecot with the hope that folder that I create will be stored in /Mail/IMAP/%u. Then I use Mozzila as my email client and change the IMAP server directory to ~nina/IMAP/ which is the link to /Mail/IMAP/nina/. But then I can not create folder anymore from Mozzila, or view any thing other than inbox. I am still able to see message in inbox since I haven't change the location of inbox. Please help. Nina

[Dovecot] authentication configuration
by Tom Allison 10 Jun '04

10 Jun '04

I've included the non-defaulted bits of my dovecot.conf file at the bottom of this email. As I understand my set-up it's using unix authentication methods (/etc/passwd via pam?). Considering disable_plaintext_auth and auth_mechanisms, what exactly is being passed? I was hoping to get auth_mechanism = digest-md5 but that's not working out very well right now. It seems I can only do plaintext authentication. I got stuck on the userdb/auth_passdb settings. Can someone give me an example of how to configure for md5-digest authentication? My current guess is: disable_plaintext_auth = yes auth = digest-md5 auth_mechanism = digest_md5 auth_passdb = /etc/mydigestfile How would I set this for pgsql? auth_passdb = /etc/dovecot-pgsql.conf ### non-default config settings. protocols = imap imaps disable_plaintext_auth = yes login = imap login_max_processes_count = 16 login = pop3 max_mail_processes = 512 default_mail_env = maildir:~/Maildir mailbox_check_interval = 1 auth = default auth_mechanisms = plain auth_passdb = pam auth_user = root

[Dovecot] configuration
by Tom Allison 10 Jun '04

10 Jun '04

I've noticed that there are some parameters mentioned in the docs that aren't identified therein (ie: login_process_per_use). Is there a more generic set of docs that can identify what each of the parameters and what they do, or at least something that will allow me a simple how to to avoid embarrasing situations. I supposed I should only settle for ssl based connections (imaps/pops) but I will be open to digest-md5 if I could. I'm also curious to see how I can use pgsql authentication with dovecot. I think this would be great to work with since I'm basing all my postfix settings around postgresql as well. But for now I'm not sure how to use postfix authentication with the file directories I'll need to use for the maildirs (and procmail!).

[Dovecot] pgsql configuration
by Tom Allison 10 Jun '04

10 Jun '04

from the pgsql configuration file: # Query to retrieve the password. # # The query should return one row, one column. If more than one row or column # is returned, authentication will automatically fail. # # Available substitutions: # %u = entire userid # %n = user part of user@domain # %d = domain part of user@domain # # Query to retrieve the user information. # # The query must return only one row. The columns to return are: # home - Home directory # mail - MAIL environment # system_user - System user name (for getting user's groups from /etc/group) # uid - System UID # gid - System GID # # Either home or mail is required. uid and gid are required. If more than one # row is returned or there's missing fields, login will automatically fail. # I'm a bit slow here, so if someone could just nod if I'm in the right direction: I want to support IMAP for at least two domains. Therefore I have to use the authentication string of: SELECT password FROM users WHERE userid = '%u' and the user must enter their entire email address for their login name. (I can do this!) I want some portion of these domains and users to be consistent with existing accounts in my /etc/passwd database. I don't expect to use passwd information for the username and password, but I want the information returned for joe(a)domain2.com to be for the user:joe in my passwd file and have his email in /home/joe/Maildir. Similarly, I want others (either fred(a)domain2.com or jane(a)domain1.com) to be (ideally) all driven under a non-local account name and login. For this second one, I'm thinking I need to do something like this in the user information query (this is mostly a guess): for joe(a)domain2.com (/etc/passwd) :: jane(a)domain1.com (no passwd) home - /home/joe --or-- can I use ~/ :: /var/spool/imap/%d/%n ?? mail - maildir:~/Maildir :: maildir:/var/spool/imap/%d/%n ?? system_user - joe :: (a guess -- adduser dovecot-imap to passwd maybe) uid - joes uid (1002) :: dovecot-imap uid (510) gid - joes gid (1001) :: dovecot-imap gid (510) with seperate group This is where I get fuzzy. If someone could help me figure out where I went wrong I would appreciate it. If I did this correctly, then in theory I could pass email delivery to procmail and have one set of rules (/etc/procmail) do some additional filtering for all the email under my domain1.com (spam filtering mostly) and perform a final delivery to maildirs in /var/spool/imap/doamin1.com/jane/ Or am I sleep deprived?

[Dovecot] dovecot newbie question about "invalid key" problem
by Joakim Verona 10 Jun '04

10 Jun '04

Hello list, I've trying to migrate a small uw-imap server to dovecot. It works somewhat, and speed seems greatly improved, so thats great. However, I get an "invalid key/Internal Error" problem when connectiong to my INBOX with thunderbird. According to google this is a well known problem with mozilla mailers. Dovecot is not lenient with this bug in thunderbird. Is there some workaround for this? I noticed that its possible to turn on some client bug workarounds for outlook. Does the same go for mozilla? I tried one described remedy, which was to delete the account information and re-register the account. This didnt help. The problem seems to be only with INBOX, which I have mapped to /var/spool/mail/<username>, not my other imap mailboxes. Im running gnus as well and the problem doesnt seem to occur there. My configuration: Redhat 9 dovecot 0.99.10.5 (from DAG repository RPM:s) Another question: Would it be possible to run uw-imap on one port, and dovecot on another? Or would that corrupt the mailstores? Regards, /Joakim

[Dovecot] Feature request?
by Stephen K. Gielda 10 Jun '04

10 Jun '04

I'd like to toss a feature request on the table for consideration. We currently use a different popd because of a feature that allows us to restrict pop access based upon an allowed users list. This is the only thing that keeps us from using the popd in dovecot currently. It's a simple text file of usernames that are allowed to use pop, if the name isn't in that list then pop access is denied. Is this something that can be considered for a future feature addition? Would anyone else also find this useful? /steve

[Dovecot] Help: RH9 upgrade (mbox)
by Guy Davis 09 Jun '04

09 Jun '04

I just upgraded my RH9 server with UW-IMAP to Fedora Core 2 and after a short try with Cyrus, I'm hoping to get Dovecot configured. My problem is getting Dovecot to recognize my old mbox mail folders. It correctly shows the INBOX contents from the /var/spool/mail/davis mbox. However, I also had a bunch of mboxes such as: /home/davis/Mail/Sent /home/davis/Mail/Lists/list1 Reading the documentation, Dovecot indicates it will recognize mbox files within the ~/mail directory. So I moved my mail over giving: /home/davis/mail/Sent /home/davis/mail/Lists/list1 Unfortunately, after restarting Dovecot and restarting my IMAP client (Mozilla), I don't see anything other than my Inbox. If I create a file (/home/davis/mail/.subscriptions) with 'Sent' in it, and restart things then I can see Inbox and Sent. This would let me have a single directory with multiple mbox files in it. However, I'm not able to get Dovecot to recurse and let me see mboxes in subfolders such as: /home/davis/mail/Lists/list1 As well, when I first connect to Dovecot via Mozilla, I get an error saying: 'The current command did not succeed. The mail server replied "Invalid mask"'. What does this mean and how do I correct it? Any help would be greatly appreciated. Thanks, Guy

[Dovecot] Setting IMAP root as user's home directory. How?
by Silviu Marin-Caea 08 Jun '04

08 Jun '04

I'm trying to set up dovecot to use /home/username as IMAP root, but it keeps creating /home/username/mail. I need /home/username in order to migrate with the least changes from uw-imap, just by copying .mailboxlist without the INBOX line in it into .subscriptions I tried each of these, one at a time: default_mail_env = mbox:~/:INBOX=/var/mail/%u default_mail_env = mbox:%h/:INBOX=/var/mail/%u default_mail_env = mbox:/home/%u/:INBOX=/var/mail/%u In each case, dovecot was stubornly creating /home/username/mail Please CC me, I'm not on the mailing list.

[Dovecot] mta/mda config
by Jure Pecar 04 Jun '04

04 Jun '04

Hi all, I'm at the stage of planning our new mail system and am evaluating dovecot for it. For large mailstore setups, it makes sense to split maildirs across many directories. I see that setting default_mail_env to something like maildir:/var/imap/domain/%1d/%d/%1u/user/%u/ would create almost identical on-disk layout as multidomain cyrus setup. Now, as dovecot does not have its own mda or lmtp daemon, how does one configure mta (eg. postfix) to deliver mail in such maildirs? Related question ... any cyrus to dovecot migration tales? :) -- Jure Pečar

[Dovecot] Advice on converting from Mbox to Maildir?
by Villalovos, John L 04 Jun '04

04 Jun '04

Does anyone have advice or pointers on good documentation on how to convert a system from using the Mbox format to using Maildir? I recently upgraded to Fedora Core 2 from Fedora Core 1 and discovered that UW-IMAP was gone. So I switched over to using Dovecot. So far so good. But I would like to convert my system to start using the Maildir format. How easy is this to accomplish? Can I keep my Inbox /var/spool/mail/user_name as an mbox format and have my other folders as Maildir? What would I have to change for Sendmail to make it use Maildir for the Inbox? Can procmail support Maildir? Any pointers or help would be much appreciated? John

I am using dovecot-0.99.10.5-1 which was on the development tree of Fedora. Though I would think the one that came stock with Fedora 2 should work as well. I have no reason to think it won't. One note. I don't use POP that much. I have one person who uses it and they haven't complained. > So if all the mail is moved to Maildir (thus eliminating the typical > mailspool), and somebody pop's onto the server, Dovecot will use the > Maildir/Inbox for the pop? Yes it will. If you read the mail-storages.txt documentation file it talks about it. I would read the section on "Detecting what to use". I did NOT set the default_mail_env variable in my /etc/dovecot.conf and it figured it out automagically :) Good luck, John

[Dovecot] 0.99.10.5 imap flag update issues

Hi, there is an issue left in 0.99.10.5 which (I think) is a problem with imap status flags. It shows up in two places: (1) When new mail is delivered to the inbox, the last read mail changes to "unread". (2) When you move mails from the inbox to another folder with Mozilla (1.6 on win32, Linux, NetBSD), they are not removed from the inbox, effectively performing a copy instead of a move. And, while I am at it, (3) I see a regular log entry from a MS Outlook 2000 SP 3 Jun 3 10:26:23 bounce imap-login: SSL_read() syscall failed: EOF [130.83.XXX.XXX] The setup here: OS NetBSD 2.0beta, MTA sendmail 8.12.11, LDA maildrop 1.3.9, dovecot 0.99.10.5, OpenSSL 0.9.7d Any ideas? hauke -- Hauke Fath /~\ The ASCII Ribbon Campaign Institut für Nachrichtentechnik \ / No HTML/RTF in email TU Darmstadt X No Word docs in email Ruf +49-6151-16-3281 / \ Respect for open standards

[Dovecot] Getting POP3 up and running

03 Jun '04

Hi! Now that I happily smiling have Squirrelmail working on the new setup (Fedora Core 2), the next hurdle seems to be getting POP3 to work. According to my understanding of the documentation I changed the protocols line in dovecot.conf to: #protocols = imap imaps pop3 pop3s then restarted dovecot, but still can't connect to pop3 (not even after rebooting the whole system). Doing an nmap on my server does not show port 110 as open. Any clues as to what I may be overlooking?

[Dovecot] Loggin error with Squirrelmail on Fedore Core 2
by Antonio Nunes 03 Jun '04

03 Jun '04

Hi! I am switching a mail server setup to a new machine which has RHL Fedore Core 2 installed, which uses Dovecot. I managed to get Squirrelmail to work on my personal account, but when logging in with some other accounts I get the following error as response: ERROR : Connection dropped by imap-server. Query: Capability I did a web search on this and found a message from Tim Middleton who experienced the same problem. He also suggests a workaround: "I put in a chron job to touch into existance any non-existing mailboxes for everyone in the passwd file periodically, which mostly eliminates the problem. But I'd still like to know why the server is having the problem, if anyone can make any suggestions." I would like to try this, but I am still fairly new to Unix. Could anyone show me how to set up such a chron job? Are there other, manual, ways to touch the mailboxes? Thanks, Antonio Nunes Don't let who you can be keep you from being who you already are.

[Dovecot] Supporting POP & IMAP with Sendmail
by John Duino 03 Jun '04

03 Jun '04

Greetings! I dug thru the archives but didn't see a clear answer to this. A client has an existing sendmail/pop3 system, and I would like to switch to dovecot for imap support. For imap I much prefer the Maildir format over mbox, however, sendmail natively dumps to mbox (mailspool) and that is what pop typically reads. I've read the threads on how to make sendmail write to Maildir. My problem is that I'd like to support both pop/mailspool and imap/maildir. While running dovecot in imap-only it will use mbox format to read the /var/mail/user as the Inbox and then create the full imap structure under ~user/mail but in mbox format, not maildir. If/when I turn on both pop and imap in dovecot will it allow this with the current config? Or will I still need to convert sendmail output to maildir...and then I assume dovecot/pop will read from ~user/Maildir/Inbox even though it is in Maildir format? Basically, if I'd prefer to not have to convert sendmail to Maildir format, have dovecot always treat /var/mail/user as the Inbox for both pop and imap, and for those who switch to imap, have it store their other folders in ~user/Maildir. Asking too much? Thanks! John

Timo says that it is NOT available in the version that comes with Fedora Core 2. It will be available in the 1.0 series by defining multiple namespaces. The current 1.0-tests allow this. > What would I have to change for Sendmail to make it use > Maildir for the Inbox? Sendmail does NOT need to be changed. > Can procmail support Maildir? Yes and that is what you need to change. I setup /etc/procmailrc to have the line: DEFAULT=$HOME/Maildir/ Make sure there is the terminating / on that line. What this will do is make all new mail that is delivered via procmail go to each user's Maildir folder. But what you need to do first is convert your existing mbox mail into maildir format. I used the program that was recommended to me: mb2md http://batleth.sapienti-sat.org/projects/mb2md/ This program worked great to convert my /var/spool/mail/user_name stuff and also folders that I had created under ~/mail/ So now my whole system is using Maildir format.

[Dovecot] dovecot and virtual hosting
by Vegard Svanberg 03 Jun '04

03 Jun '04

Hi. A usual hosting provider setup depends on having one IP ("virtual mailserver") per domain. Using dovecot on servers handling hundreds or thousands of domains today equals to having multiple instances of dovecot running. This problem could be solved by making dovecot take into account the IP address the user connects to and authenticate against the proper {database, table, pw-file, [...]} based on that.

[Dovecot] IMAP folders missing after migrating to Dovecot
by Chris Horry 03 Jun '04

03 Jun '04

[Dovecot] Serve list archives by dovecot IMAP
by Kenneth Porter 02 Jun '04

02 Jun '04

Has anyone considered setting up a Dovecot public server to serve the list archives by IMAP? Or does Dovecot not do anonymous read-only access? (I note by comparison that the Cyrusoft Mulberry list archives are served by an IMAP server. <http://www.cyrusoft.com/mulberry/support/anonimap.html>) It should be sufficient to set up Dovecot on some server in the dovecot.org domain and subscribe it to the lists.

[Dovecot] Dovecot + SSL + Fedora
by David Keegel 02 Jun '04

02 Jun '04

I've been seeing the Dovecot/SSL/Fedora 1 problem. I have a dovecot server which tends to die at least once a day, with messages like these :- May 24 13:44:44 mail pop3-login: RAND_bytes() failed: error:24064064:random number generator:SSLEAY_RAND_BYTES:PRNG not seeded May 24 13:44:44 mail dovecot: Login process died too early - shutting down I noticed Timo's email about this at: http://www.dovecot.org/list/dovecot/2004-May/003316.html with the patch that just ignores the return code of RAND_bytes(). Would disabling SSL in dovecot.conf also be a reasonable way of avoiding the problem of dovecot crashing? My plan is to set ssl_disable = yes and also take out pops and imaps from protocols. That is a lot easier for me than getting source, patching it, re-compiling and re-installing. We are using Fedora Core 1 (fedora-release-1-3 i386 rpm) Dovecot 0.99.10 (dovecot-0.99.10-4 i386 rpm) OpenSSL 0.9.7a (openssl-0.9.7a-33.10 i386 rpm) ___________________________________________________________________________ David Keegel <djk(a)cybersource.com.au> http://www.cyber.com.au/users/djk/ Cybersource P/L: Linux/Unix Systems Administration Consulting/Contracting

[Dovecot] 0.99.10.5 release candidate
by Timo Sirainen 02 Jun '04

02 Jun '04

http://dovecot.org/rc/ Thought I'd still make one 0.99.10.x release now that mbox corruption problems are (hopefully) fixed. Please test, if no problems are found this will be the final 0.99.10.5. Changes since .4: + MySQL authentication, patch by Matthew Reimer - mbox: APPEND reversed given \Draft and \Deleted flags - mbox: "LF not found" errors happened sometimes when X-IMAPbase header was updated. Possibly corrupted mbox sometimes. Thanks to Fabrice Bellet for finding this bug. - Custom flags couldn't be unset - Maildir: make sure ":2," is appended to filename when moving mails from new/ to cur/.

[Dovecot] Postfix SASL AUTH from Dovecot
by Timo Sirainen 02 Jun '04

02 Jun '04

Again today got annoyed at Cyrus SASL. Upgrading it to newer version had broken PAM support. Trying to login as "user@domain" resulted it only asking for "user" from PAM. Well, got it patched and working again, but I'd rather not go through it all the time.. So I finally did what I had been thinking about a year or so, change Postfix to use dovecot-auth directly. This required cleaning dovecot-auth quite a lot, but it seems to be working now. Actually I finally implemented support for initial SASL response as well. POP3's AUTH command had required support for it, strange that no-one ever complained about it not working. If you want to try it, you need very latest CVS version of Dovecot and this patch for Postfix: http://dovecot.org/patches/postfix-dovecot-auth.patch dovecot-auth can be run on it's own (configuration in environment variables), or you can use extra_sockets auth setting which is a ':' separated list of UNIX sockets where to listen in. You'd probably want to set it to /var/spool/postfix/etc/dovecot-auth, the location is hardcoded to /etc/dovecot-auth in the patch for now (smtpd is chrooted). The only real problem is that Dovecot creates the dovecot-auth socket using 0660 root:root modes, so you have to manually chmod it to 0666 or fix owner/group. I guess that needs some more thinking.. Probably each socket should have separate settings for it, but how to do it easily in configuration? .. The patch has also hardcoded dovecot path in Makefile.in, you'll need to change that.

[Dovecot] IMAP login name conversion
by Zoong Pham 01 Jun '04

01 Jun '04

Hi all, Out IMAP client (Outlook and others) use login name like joedirt(a)domainname.com I need dovecot to convert it to joedirt-domainname_com since that is the local login name. Can someone give me a hint how to do that? Is there any simple way to do it or do I have to modify any source code? Thanks, Zoong

Aloha. The current CVS snapshot and 1.0-test14 will not build on Solaris 8 because it does not provide a sendfile() funtion. It just has sendfilev(). Solaris 9 has sendfile(), though. Using the old sendfile-util.c from 1.0-test1 and setting HAVE_SOLARIS_SENDFILEV instead of HAVE_LINUX_SENDFILE in config.h works. Greetings, Andy.

[Dovecot] Small change to make dovecot pop3 uw-imap migration friendly
by Oleg I. Vdovikin 01 Jun '04

01 Jun '04

Hi, today I've finished migration from uw-imap daemons to shiny and fast dovecot. With thanks of dovecot my mail server load average drops by factor of ten even with ancient unix mailboxes. ;-) So, the only thing I've discovered is what POP3 uidls are different than ones used in the uw-imap. Luckily, the difference are only in the format string used in uidl response. So, I've made the following change in the code --- dovecot-0.99.10.4.orig/src/pop3/commands.c 2003-05-28 15:17:15.000000000 +0400 +++ dovecot-0.99.10.4/src/pop3/commands.c 2004-05-27 14:06:48.000000000 +0400 @@ -374,7 +374,7 @@ while ((mail = client->mailbox->fetch_next(ctx)) != NULL) { client_send_line(client, message == 0 ? - "%u %u.%u" : "+OK %u %u.%u", + "%u %08x%08x" : "+OK %u %08x%08x", mail->seq, client->uidvalidity, mail->uid); found = TRUE; } and got everything just like in the old uw-imap pop3. I'm current running RH9, but thinking of FC2 which uses dovecot. So, I've rebuild the FC2 rpm for RH9 including this patch. Pop3 users, which do not remove their mails from the server are really happy - they do not receive old mails twice. Probably this small change could be applied to the 1.0, or used as a config option. Any suggestions are greatly appriciated. Thanks, Oleg.

[Dovecot] 1.0-test14
by Timo Sirainen 31 May '04

31 May '04

http://dovecot.org/test/ Maildir syncing is still somewhat broken. I can't really figure out what the problem is. Maybe it's in indexes after all which are just causing bugs in syncing. I think I'll finish implementing mbox syncing and see if same problems appear with it. This release has mostly dovecot-auth changes: - Delay reporting failed authentications - Log IP address of failed authentications (if verbose = yes) - Password schemes can now be loaded from plugins. Example: http://dovecot.org/patches/1.0/password-scheme-lmpass.c - (now that I think of it, auth mechanisms could be implemented as plugins as well if they were placed in password-scheme directory, I think I'll change the directory name so it's more logical) - SASL initial responses are supported (POP3) - SHA/SHA1 password scheme implemented with OpenSSL - dovecot-auth can run as standalone process now (but that doesn't work with Dovecot itself at least yet) - Changes to make it more easier to use it outside Dovecot (eg. the Postfix patch) Added new variables which can be used: %l - local IP address %r - remote IP address %P - PID Added mail_log_prefix setting where variables can be used. So if you want eg. "imap(user,ip-addr,pid): ", set it to "%p(%u,%r,%P): ". And others: - added maildir_stat_dirs setting - several bugfixes for indexes

[Dovecot] Dovecot returns everything starting with "." as folder
by Christoph Hohmann 30 May '04

30 May '04

Hi, I'm using dovecot imapd 0.99.10.5 from debian unstable and I noticed that dovecot returns everything in the maildir folder that starts with a "." as a folder as the result of LIST "" "%" command without checking if it is really a maildir folder (must contain the directories cur, new, tmp and the file maildirfolder). This is a little bit annoying because it also returns Sylpheed's cache files '.sylpheed_cache' and '.sylpheed_mark' if they exist in the maildir. -- http://reboot.animeirc.de http://sylpheed-claws.sourceforge.net/

[Dovecot] dovecot API / Virtual Folders?
by James Moser 30 May '04

30 May '04

I was wondering if anyone has done something like this, or knows of any reason it would not work. Would it be possible to use dovecot's API to create virtual folders where when messages are placed in them some other application can be executed on them? With programs like DSPAM and SpamAssassin, and with users who do not have shell access to the machines, it would be nice if there was a way they could do something like this to use dspam/sa-learn, that way they could use it with any mail application. I don't like the idea of using cron to do this. -- James L Moser james(a)powweb.com PowWeb Hosting http://www.powweb.com /(bb|[^b]{2})/, that is the Question. mysql>SELECT * FROM user WHERE clue > 0; Empty set (0.03 sec) Health is merely the slowest possible rate at which one can die...

[Dovecot] dovecot and nfs
by Dan Stromberg 30 May '04

30 May '04

I configured dovecot on a Fedora Core 2 system - the version that comes with FC2. I was using it with a RHEL 3 NFS server. Dovecot would again and again get stuck trying to grab an fcntl lock, even though I specified that it should only use dotlocks in dovecot.conf. Sometimes it would segfault (leaving things locked?). Often there would be two dovecot imapd processes for the same user. I've since moved dovecot onto our internal NFS server, but we have many (relatively) external imap servers where it might be nice to use dovecot, and in a number of those scenarios, NFS would be a requirement. Thanks. -- Dan Stromberg DCS/NACS/UCI <strombrg(a)dcs.nac.uci.edu>

[Dovecot] Messages does not appear in OE6
by Mauricio Araya V. 29 May '04

29 May '04

Hi List! I have an issue with dovecot: Outlook express users sometimes can't see some emails (they are not even listed) that can be seen with other IMAP clients, I tested it (and it works) with Evolution, Outlook and SquirrelMail (a web mail). Please note that this is not the client bug reported at http://dovecot.org/clients.html with the message: "Message is no longer available on this server" I have the following configuration: - Postfix as MTA (ver. 2.1), using the Maildir format to store messages. - Dovecot 0.99.10.4_2 serving POP3 and IMAP. Relevant dovecot config: client_workarounds = oe6-fetch-no-newmail outlook-idle default_mail_env = maildir:/%h/Maildir Something important is that I am using freebsd 4.9, and dovecot is installed from ports (/usr/ports/mail/dovecot) Does anyone has the solution for this problem, or at least an idea of what causes it?

[Dovecot] IMAP views - and things to make Outlook Express not suck so much
by Geo Carncross 28 May '04

28 May '04

Some of the things that keep being brought up SEEM TO ME to be a form of IMAP crack that can be accomplished in a much more generalized manner with a little bit of thought. An idea I had a while back was for IMAP views. It accomplishes the four things I keep seeing on this list without being specific to any of them. Consider new configuration variables: rewrite Junk { folder = INBOX search = KEYWORD "Junk" post = +FLAGS (Junk) } rewrite Trash { folder = * search = DELETED fetch = -FLAGS (\Deleted) post = +FLAGS (\Deleted) } Views would not be deletable (unless one wants to invent some nonstandard IMAP extensions today), but they would otherwise look like regular folders. One could post and search and fetch messages as normal (with some alterations to various IMAP fields). In the examples I gave: A001 SELECT Junk A002 SEARCH ALL A003 SELECT Trash A004 SEARCH ALL A005 FETCH 1 FLAGS would be translated into: A001 SELECT INBOX A002 SEARCH ALL KEYWORD Junk A003 SELECT {for each SUBSCRIBED folder} A004 SEARCH ALL DELETED A005 FETCH 1 FLAGS Except, A005 would actually yield: * 1 FETCH (FLAGS ()) Instead of: * 1 FETCH (FLAGS (\Deleted)) It would probably be ideal if these were configurable per-user, but I'd be happy with system-wide rewriting. Options for rewrite could include: folder = folders that could be selected using LSUB OR a valid (existing) folder name. If this is system wide, pretty much only INBOX, INBOX.% and INBOX.* and * and % are valid :) search = tags to append to SEARCH operations on the view fetch = IMAP fields that are acceptable to STORE that we will pretend occurred when fetching. recent = IMAP fields that should be STORE'd when the \Recent flag is still set. post = IMAP fields that are acceptable to STORE that we will perform when APPENDing or STOREing. append = argument to be passed to /bin/sh -c which will receive on standard input the APPENDed body, and produce on output a STOREed body. open = argument for /bin/sh -c for when this view is SELECTed or EXAMINEd close = argument to be passed to /bin/sh -c for when the view is closed. index = argument to be passed to /bin/sh -c for when dovecot wants to index a portion of the message. standard input of the argument is the message, whereas standard output is the portion to actually index. path = a regular dovecot mailbox path that would contain the real contents of this folder. ro path = like path, but would be decidedly read-only (except for any side-effects generated by append =) Subprocesses that exit 99 would handle the task internally- thus any normal actions (such as for index = and append =) would not occur. Exit code 0 is for normal completion, and all other exit codes should generate an error. If one allowed open = and close = to be used on REAL folders, this would allow people to actually have the behavior UW-IMAP does by MOVING mail from /v/s/m into ~/mbox... One could use append = with a "Outbox" view that could write the queue at the same time as storing a copy into Sent Items. One could also use append for gpg-signing messages as they're being recorded. One could also use append for publishing to a mailing list. One could use index = to spell-check messages beforehand thus improving my chances of actually finding messages from my PHB. One could also use append =, recent = and ro path = to emulate shared folders support in a manner that would be useful for using IMAP folders as a kind of work-queue. Thoughts?

[Dovecot] dovecot immediately exits on Fedora 2
by Per Bothner 26 May '04

26 May '04

I "upgraded" my server running UW-IMAP on Fedora 1, to Fedora 2, which defaults to Dovecot. Unfortunately, the server refuses connecions from my client (Mozilla). It seems that Dovecot immediately exits: ps aux|grep dovecot shows nothing. Also, if I manually start up dovecot, it immediately exits, with no messages. (It does at least parse the config file, since tweaking that gives me errors.) What is surprising is that I haven't been able to "Google" to find anone else reporting someting similar, so I'm wonderring what makes my system unique. I tried downloading, compiling and running the current UW-imap. Mozilla is able to connect to it, and ask for a password, but rejects the login. Curious that we're getting two such very different failure modes. Help would be most appreciated; for now neither I nor others who use my imap server can access our mail (except by directly viewing the /var/spool/mail file). -- --Per Bothner per(a)bothner.com http://per.bothner.com/
