[Dovecot] Worthwile to use quotas?
by Peter Clark 24 Dec '04

24 Dec '04

I'm aware that dovecot doesn't support Maildir++ quotas yet (pity). However, is it still worthwhile to set up something like Postfix + Maildrop to use quotas, or is dovecot's lack of support just going to throw a wrench in the works? Thanks, :Peter

[Dovecot] Purging /var/mail/username ?
by Michael Hipp 24 Dec '04

Dovecot is delivering mail to my ~/.mail directory wonderfully. But /var/mail/michael is growing steadily. Is it the job of Dovecot to purge this file regularly? Is there a setting somewhere for this? Thanks, Michael

There's good reasons to use Maildir, and there's good reasons to stay with mbox, but avoiding /var/mail is not one of them. mbox is the "classical" format, and Timo (I assume) chose to setup dovecot to use the "classical" location scheme as well, which is to store incoming mail below /var/mail and let users pull it from there and store it however they want at their personal folder below /home. If you are new to all this, actually there is probably a good point in staying close to the "classical" way of doing things, so that you can get help from more sources. I suggest keep receiving mail below /var/mail as mbox files, and play around with mbox and Maildir storage for different (test-)users below /home.

[Dovecot] error when popping mail over DSL
by Jeff Ramsey 23 Dec '04

23 Dec '04

Hi, I have a user who is getting a strange error when popping his mail over a DSL line. The error in my log file is as follows: file client.c: line 237 (client_send_line): assertion failed: ((size_t)ret == str_len(str)) I can POP his mail just find here locally connected to the server via 100bT, but over his DSL link, he gets this error. His mailbox size is 24MB, and he is using outlook w/ the option 'leave a copy of messages on the server'. He has Outlook 2003 and we use Dovecot 1.0 test 42. Is there a timeout limit on the pop3 server? -- Jeff Ramsey MIS Administrator Tubafor Mill, Inc.

[Dovecot] Need subfolders - convert to Maildir & how?
by Michael Hipp 22 Dec '04

22 Dec '04

I just installed Dovecot and it is working great. But I need subfolders. Does this mean I need to convert to Maildir format? I found several tools to do the conversion, but is there anything that needs to be changed in Dovecot to make the switch? Any advice appreciated. Thank you, Michael Hipp Heber Springs, AR, USA

[Dovecot] Mixing mbox and maildir
by Kenneth Porter 22 Dec '04

22 Dec '04

Is there some way to add a maildir folder to a mbox hierarchy? My folders are all mbox, but I want to migrate some client-side mail from a client (PMMail2000) that stores messages as individual files, and it might be easiest just to dump all the files into a maildir directory with suitable naming.

[Dovecot] moving messages with bash
by Todd Slater 22 Dec '04

22 Dec '04

I use bogofilter and a script or two to manage junk mail on my home box (fetchmail from POP3, postfix and procmail to local maildirs, mutt for MUA). Since these mails are just files I figured it never mattered that I moved them from one folder to another via a bash script, but some posts on this list make me think I shouldn't do that on a server running dovecot (IMAP). What I currently have is a MakeJunk folder (maildir) that I drop spam that was missed into, then a cron job runs mail in that folder through bogofilter and moves it to a Junk folder. Is it sane to do that with simple mv, or do I need to use some special imap command? Confused, Todd

[Dovecot] 0.99.13-rc2
by Timo Sirainen 21 Dec '04

21 Dec '04

http://dovecot.org/rc/ Another one. Unless there are some bugs this will be the final version in a few days. * GNUTLS support hasn't been working for a while, so it's not even tried to be used anymore unless explicitly wanted. + Added CRAM-MD5 authentication mechanism. Patch by Joshua Goodall + Added SMD5 password scheme support and changed MD5 scheme with LDAP to act as PLAIN-MD5 rather than as MD5crypt. Patch by Joshua Goodall + Workaround for some POP3 client bugs: if message doesn't contain the "end of headers" empty line, add it automatically. - SQL and LDAP authentication was broken - SEARCH UNKEYWORD wasn't working

[Dovecot] Stalled Authentication, Great Clues
by Richard Petty 21 Dec '04

21 Dec '04

I've just installed Dovecot 0.99.12.1 onto a White Box EL 3 server. I'm mostly following the email server setup instructions at http://www.wanderingbarque.com/mailserver.html and getting Dovecot to work is the last task to complete. I've compiled Dovecot with LDAP support. I'm authenticating Postfix via SASL to the LDAP database just fine, and I also authenticate and manipulate LDAP info from JAMM very well, too. However, Dovecot authentication seem to hang up when a correct password is submitted (POP or IMAP... it doesn't matter). Here's an example of the problem: [root@kayak /etc] telnet localhost 110 Trying 127.0.0.1... Connected to localhost.bramble.com (127.0.0.1). Escape character is '^]'. +OK dovecot ready. user repetty(a)bizzy.mine.nu +OK pass bogeybogey sadf hello? ^] telnet> q Connection closed. As you can see, once I hit the return key to submit the password I do not get another prompt. In fact, Dovecot doesn't respond at all although it seems to respond to the escape character just fine. Additionally, dovecot-auth starts soaking up CPU time... until I kill the process (dovecot-auth must be killed manually.) 22:15:32 up 32 days, 21:40, 5 users, load average: 1.05, 1.02, 0.98 121 processes: 119 sleeping, 2 running, 0 zombie, 0 stopped CPU states: cpu user nice system irq softirq iowait idle total 50.5% 0.0% 0.5% 0.0% 0.0% 0.0% 48.8% cpu00 66.7% 0.0% 0.0% 0.0% 0.0% 0.0% 33.2% cpu01 34.4% 0.0% 1.1% 0.0% 0.0% 0.0% 64.3% Mem: 318260k av, 300740k used, 17520k free, 0k shrd, 24380k buff 141540k actv, 28364k in_d, 3864k in_c Swap: 655352k av, 80868k used, 574484k free 94736k cached PID USER PRI NI SIZE RSS SHARE STAT %CPU %MEM TIME CPU COMMAND 23846 dovecot 25 0 1928 1928 1352 R 49.7 0.6 27:30 0 dovecot-auth 23847 dovecot 15 0 1072 1072 868 S 0.0 0.3 0:00 1 imap-login 23848 dovecot 15 0 1072 1072 868 S 0.0 0.3 0:00 1 imap-login 23849 dovecot 15 0 1160 1160 936 S 0.0 0.3 0:00 1 imap-login 23850 dovecot 15 0 1136 1136 928 S 0.0 0.3 0:00 0 pop3-login 23851 dovecot 15 0 1140 1140 928 S 0.0 0.3 0:00 1 pop3-login 23852 dovecot 15 0 1140 1140 928 S 0.0 0.3 0:00 0 pop3-login 23858 dovecot 15 0 1068 1068 868 S 0.0 0.3 0:00 0 imap-login 23870 dovecot 15 0 1064 1064 864 S 0.0 0.3 0:00 1 pop3-login 23886 dovecot 15 0 1060 1060 864 S 0.0 0.3 0:00 1 pop3-login 23916 dovecot 15 0 1064 1064 864 S 0.0 0.3 0:00 0 pop3-login From the client's point of view, the server never seems to come back after the account password is submitted. Dovecot's log shows that it eventually times out the client, although the client never seems to get wind of this: pop3-login: Dec 19 22:13:08 Info: Disconnected: Inactivity [192.168.0.6] I know that Dovecot is connecting to the LDAP server because if I mess up the Dovecot LDAP password in the dovecot.conf file I get an authentication error (as I should): dovecot-auth: Dec 19 20:52:19 Error: LDAP: ldap_simple_bind_s() failed (dn cn=dovecot,dc=dillo,dc=info): Invalid credentials Again, if client submits an incorrect email account password everything works as it should: Dovecot tells the client that the password is incorrect, over and over, if necessary. However, if the password is entered correctly then Dovecot hangs up for good. --Richard

[Dovecot] Postfix + dovecot-auth
by Timo Sirainen 20 Dec '04

20 Dec '04

I wrote a patch to Postfix which now supports SMTP AUTH using dovecot-auth. This time it doesn't need any Dovecot libraries and it's backwards compatible with Cyrus SASL by default. You'll just need to set one variable in Postfix config file to enable it. Patches and instructions in: http://dovecot.org/patches/postfix/ Not very well tested yet though. And it doesn't work with 1.0-test59, you'll need to have at least today's nightly snapshot.

[Dovecot] Just delete that index
by Doug Luce 20 Dec '04

20 Dec '04

I get a few messages of this ilk each day: Dec 16 01:56:31 aurora dovecot: IMAP(doug): Corrupted index cache file /home/doug/Maildir/.users.joe/dovecot.index.cache: indexid changed I usually address this by deleting dovecot.* in the directory of issue. I was thinking that I could instead just have the server delete these files and attempt to recreate them, and skipping that error message unless the re-created files are also corrupted. Any problems with this approach? Thanks, Doug

[Dovecot] Error indexing mbox file /var/mail/seb: LF not found where expected
by Sebastian 20 Dec '04

20 Dec '04

Howdy all, Dec 19 14:24:53 dev imap(seb): Error indexing mbox file /var/mail/seb: LF not found where expected I just installed version dovecot-0.99.12.1 for the first time on FreeBSD 4.10 stable. This error occurs when I try to check my mail from a remote client and I have new messages. Here is my configuration: http://unf.be/dovecot.conf It's very close to the default install. In attempts to remedy the problem, I set "mail_read_mmaped = no", but the problem persists. I'm not sure if it's relevent, but I'm receiving mail with postfix and my mail file has lines that end with \r\n Thanks in advance for any help Sebastian -- ------------- buddhahead(a)gmail.com

[Dovecot] Auth Mechanism
by Tom Allison 19 Dec '04

19 Dec '04

Uh... I'm trying to debug an application and keep running into this: DEBUG: Sending: 1 AUTHENTICATE CRAM-MD5 DEBUG: Sent 25 bytes DEBUG: Read: 1 NO Authentication failed: Unsupported authentication mechanism DEBUG: Read: * BYE Disconnected for inactivity. So is this really asking for "digest-md5" or am I S.O.L? IIRC these are different protocols, but it's a bit early for my head to get this together.

[Dovecot] Authentication problems
by Rory Campbell-Lange 19 Dec '04

19 Dec '04

Hi. I aim to provide pop3 and imap services to a few users. At the moment I only offer imap for squirrelmail users. However, I can't login successfully for pop3. It appears to be trying to auth against PAM, rather than directly using the passwd-file. Thoughts? Thanks, Rory Config: uthenticatprotocols = pop3 imap ssl_disable = yes login = imap login = pop3 mail_extra_groups = mail auth = default auth_mechanisms = plain auth_userdb = passwd-file /etc/dovecot.passwd.conf auth_user = root auth_verbose = yes Password file: # squirrelmail imap users user1:xe9l8sIMpcTsg:1008:1008::::chroot:Maildir:/home/cmp/Maildir/user1 user2:m7VKCgWVmZYMY:1008:1008::::chroot:Maildir:/home/cmp/Maildir/user2 user3:ELh9mthLVjEG2:1008:1008::::chroot:Maildir:/home/cmp/Maildir/user3 # normal users xyz1:QtR.iN1DbL/UM:1004:1004::::chroot:mbox:/var/mail/xyz1 xyz2:y38.qLIgrvYic:1002:1002::::~/Mail:mbox:/var/mail/xyz2:INDEX=/home/xyz2 ...

[Dovecot] 1.0-test59
by Timo Sirainen 19 Dec '04

19 Dec '04

http://dovecot.org/test/ No-one had been testing 1.0-tests with Evolution? It was pretty much completely broken with messages having attachments. - test58's output stream code change were entirely wrong and caused bad breakages with mbox. - Named pipes are now treated as write-only mboxes (blocks if no-one is reading, perhaps it should timeout in a few seconds?) - FETCH BODY[n.xxx] replies were all wrong - LDAP authentication was crashing - pop3_uidl_format=%f from Andrey test60 will probably have keyword support. Its index file code is already working, with ability to set over 500k different keywords per mailbox (because message record size is limited to 65535 bytes - should be enough for everyone :). Code is still missing to notify other session about keyword changes, and storing the keywords into mbox/maildir. For mbox I can use X-Keywords header. There should probably be some configurable limit to how many keywords to set per mailbox.. Dovecot shouldn't mind if the X-Keywords header is huge, but other programs might. For maildir then.. I think I'll just implement it backwards compatible with 0.99.x, ie. store in maildir filename with a-z letters. That would make max. 26 keywords per mailbox. Except maybe I shouldn't limit it to that. The rest could be stored only in indexes. That however would make it necessary to keep indexes backwards compatible forever so data is not lost.

[Dovecot] 0.99.13-rc1
by Timo Sirainen 19 Dec '04

19 Dec '04

http://dovecot.org/rc/ I guess the RCing in 0.99.12 didn't help that much. SQL/LDAP authentication crashed because memory was freed wrong. Please test so it would actually work in 0.99.13. Also fixed SEARCH UNKEYWORD which wasn't working. Also added 1.0-test's oe-ns-eoh POP3 workaround built-in.

[Dovecot] Cygwin and index code
by Johannes Berg 19 Dec '04

19 Dec '04

As I can currently only work with windows (eek) I thought I'd try dovecot there. I already sent a patch to make dovecot compile under cygwin, but it still doesn't really work, here's part of a session that I started while my maildir was totally empty (only cur/new/tmp in ~/Maildir) $ ./imap.exe * PREAUTH [CAPABILITY IMAP4rev1 SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN NAMESPACE LOGIN-REFERRALS] Logged in as jmberg A01 SELECT INBOX imap(jmberg): Warning: Compressing cache file /home/jmberg/Maildir/dovecot.index.cache imap(jmberg): Error: open() failed with file /home/jmberg/Maildir/dovecot.index.tmp: Permission denied A01 NO Internal error occured. Refer to server log for more information. [2004-12-17 15:51:06] A02 LOGOUT * BYE Logging out A02 OK Logout completed. A second session (some files were created by the first) yields this: $ ./imap.exe * PREAUTH [CAPABILITY IMAP4rev1 SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN NAMESPACE LOGIN-REFERRALS] Logged in as jmberg A01 SELECT INBOX imap(jmberg): Error: open() failed with file /home/jmberg/Maildir/dovecot.index.tmp: Permission denied imap(jmberg): Error: rename(/home/jmberg/Maildir/dovecot.index.tmp, /home/jmberg/Maildir/dovecot.index) failed: Permission denied A01 NO Internal error occured. Refer to server log for more information. [2004-12-17 15:52:25] A02 LOGOUT * BYE Logging out A02 OK Logout completed. I think this is probably due to the indexing code opening the .tmp file and then unlinking it and trying to re-create it while the first is still open. Or something, I really am not sure. *Maybe* the index code might be made work if it creates a new temporary file-name every time it re-creates the file, but I don't understand the code well enough (yet) to give a better analysis of the problem. However, I do not think that this is really important. I certainly don't want to run dovecot on windows (I only saw cygwin compile in the todo and since I have a cygwin setup anyway I thought I'd try). The whole thing doesn't work anyway: [after correcting users, making directories, make install...] $ /usr/local/sbin/dovecot.exe dovecot: Dec 17 16:03:17 Info: Dovecot v1.0-test58 starting up dovecot: Dec 17 16:03:18 Error: login: fd_read() failed: Function not implemented dovecot: Dec 17 16:03:18 Error: close(mail client) failed: Bad file descriptor dovecot: Dec 17 16:03:18 Error: Login process died too early - shutting down dovecot: Dec 17 16:03:18 Error: imap-login: dovecot: Dec 17 16:03:18 Fatal: setrlimit(RLIMIT_DATA, 32): Invalid argument dovecot: Dec 17 16:03:18 Error: login: fd_read() failed: Function not implemented dovecot: Dec 17 16:03:18 Error: close(mail client) failed: Bad file descriptor dovecot: Dec 17 16:03:18 Error: imap-login: dovecot: Dec 17 16:03:18 Fatal: setrlimit(RLIMIT_DATA, 32): Invalid argument dovecot: Dec 17 16:03:18 Error: login: fd_read() failed: Function not implemented dovecot: Dec 17 16:03:18 Error: close(mail client) failed: Bad file descriptor dovecot: Dec 17 16:03:18 Error: imap-login: dovecot: Dec 17 16:03:18 Fatal: setrlimit(RLIMIT_DATA, 32): Invalid argument dovecot: Dec 17 16:03:18 Error: auth(default): dovecot: Dec 17 16:03:18 Fatal: setrlimit(RLIMIT_DATA, 256): Invalid argument dovecot: Dec 17 16:03:18 Error: child 2176 (auth) returned error 89 dovecot: Dec 17 16:03:18 Error: child 2192 (login) returned error 89 dovecot: Dec 17 16:03:18 Error: child 2212 (login) returned error 89 dovecot: Dec 17 16:03:18 Error: child 2232 (login) returned error 89 Maybe someone cares.

[Dovecot] 1.0-test58
by Timo Sirainen 19 Dec '04

19 Dec '04

http://dovecot.org/test/ - Fixed APPEND hanging in some situations. Didn't happen with mail_save_crlf=yes. - Added pop3_uidl_format setting. No need to patch sources anymore if you don't want the default. Does anyone want pop3_uidl_xuidl_header yes/no setting, with fallbacking to pop3_uidl_format if X-UIDL header isn't found? Shouldn't be difficult to do.. - Added mbox_very_dirty_syncs setting which tries to avoid re-reading mbox as long as possible. - CREATE dir/ wasn't working - If login_process_per_connection=no and auth process count > 1, each auth process listens in different socket. Login processes then connect to all these sockets and send requests to them in round robin. - Multiple auth sections in config file work now a bit better. dovecot-auth might still complain about timeouts though.

[Dovecot] deploying dspam
by Johannes Berg 17 Dec '04

17 Dec '04

Hi everyone, I've been thinking of phasing out my spamassassin installation (it's hardly doing me any good these days) in favour of dspam. Now since I'm working on this anyway, I thought I'd configure it so when users get any spam, it is delivered into a special folder. I figure I need the 1.0 test series for this, so I can make that folder fixed. But, I also want to allow them to move spam in and out of that folder and dspam can learn it. Anyway, I found a message dating back a while where Timo says this could easily be implemented in a plugin (in the 1.0 test series), but I can't put my finger on how to do it. Does anyone have an example plugin that can run commands when mail is moved in or out of a special folder? Or is there any plugin-writing documentation? Thanks, johannes

[Dovecot] IMAP Subdirectories
by Rory Campbell-Lange 16 Dec '04

16 Dec '04

Hi Using Apple Mail I cannot make subdirectories within new directories I have made on a Debian Dovecot-driven IMAP server (version 0.99.11-3). Some users, having used Exchange, expect to be able to do this. However I can't make it happen, even after doing some tests by chmod-ing the top-level directories to 777 and enabling the mail_full_filesystem_access = yes option on a test install. Views, comments and remarks much appreciated! Rory -- Rory Campbell-Lange <rory(a)campbell-lange.net> <www.campbell-lange.net>

[Dovecot] 1.0-test57
by Timo Sirainen 16 Dec '04

16 Dec '04

http://dovecot.org/test/ Two important fixes: - Fixes the recently reported dovecot-auth crashes with unexpected client input - Fixes mbox corruption in some not-so-common cases. Hopefully this is the last one. I added more asserts anyway which try to catch similiar mistakes and avoid losing data. Others: - Added oe-ns-eoh workaround for pop3. Fixes outlook/netscape problems with buggy mails. - lock_method = dotlock works now properly - Cache file compression crashed in some situations - auth_cache fixes from Andrey Also I have about 80% of the code written for keywords support. It's about the last major missing feature from v1.0, so naming should change into 1.0-alphas soon. From there on it should be mostly about stabilization, cleaning up the code and maybe some optimization.

[Dovecot] Dovecot SQL auth problem? (1.0-test52-56)
by Andrew Hutchings 16 Dec '04

16 Dec '04

Hi there, We are living dangerously and using the test versions on our production servers which are migrated from 3 different older servers (about 5000 accounts) therefore we have 3 different MySQL auths. All seems to be ok, but a guy in the office is using Thunderbird as pop3 access. The auth is saying: auth(sql): plain(?,xx.xxx.xx.xxx): invalid input I have hidden his IP for security reasons. The login should be user(a)domain.co.uk and his account works fine with outlook. With test 52 this killed the auth child with signal 6 and 11. Anyone have any ideas? Unrelated to this (I hope) we are also getting quite a few child xxxx (pop3) killed with signal 11 several times a minute. -- Andrew Hutchings Systems Operator / Developer / Linux Guru Netserve Consultants Ltd. http://www.domaincity.co.uk/

[Dovecot] KMail + dovecot
by Timothy Murphy 16 Dec '04

16 Dec '04

Is anyone running docecot on a home LAN. to give an IMAP feed to other machines on the LAN? I am running dovecot on my desktop, alfred. I want to collect email on my laptop, william, using KMail. As far as I can tell, dovecot is running perfectly. I can bring email from /var/spool/mail/tim on alfred to the same directory on william by running "fetchmail alfred" on william. I can then read it with KMail on william, so there is not real problem. However, KMail does not seem to be able to collect email directly from alfred, even though I have added an entry in KMail=>Settings=>Configure KMail=>Network=>Receiving giving type imap, Name (dovecot), Login, Password, Host (alfred), Port (143). and Prefix to Folders "/var/spool/mail". I don't see any error message anywhere, but when I click on File=>Check mail in dovecot it says "Checking account dovecot for new mail". but nothing appears to happen. Any suggestions or advice gratefully received. -- Timothy Murphy e-mail (<80k only): tim /at/ birdsnest.maths.tcd.ie tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland

[Dovecot] Dovecot and PHP
by Don 16 Dec '04

16 Dec '04

Has anyone successfully compiled PHP 5 with the -imap option using Dovecot server? I get the error: "Cannot find rfc822.h. Please check your IMAP installation". It seems that Dovecot has no development libraries so I am stuck? Will I have to scrap Dovecot and use another server like Cyrus? Thanks, Don --- Outgoing mail is certified Virus Free.

Hi folks. New to both dovecot and openldap. Trying to set up virtual domains using the wanderingbarque howto: http://www.wanderingbarque.com/mailserver.html Platform is RH enterprise 3. Only difference is I'm trying to use phamm instead of jamm: http://phamm.rhx.it/ dovecot doesn't seem to want to play nice with my openldap; everything else (postfix, etc) seems to work alright.

[Dovecot] IMAP crashes with signal 10 (SIGBUS)
by Joseph Tam 15 Dec '04

15 Dec '04

Any idea on what's causing this? Description: imap process crashed with SIGBUS. Versions: OS: Solaris 8, 9 Dovecot: 1.0-test57 Gcc: 3.2 Configure options: env CC=gcc CFLAGS="-O -g" ./configure \ --prefix=/var/dovecot \ --disable-ipv6 \ --with-ssl=openssl \ --with-ssldir=/etc/ssl \ --with-passwd-file \ --without-bsdauth \ --without-checkpassword \ --without-pam \ --without-passwd \ --without-shadow \ --without-vpopmail \ --without-static-userdb \ --without-libiconv-prefix \ --with-storages=mbox \ --with-pop3d Interestingly, eliminating optimisation seems to get rid of the problem, suggesting it might be a compiler problem. I've also tried gcc flags "-m32", "-m64", "-O3", "-O2", "-O1" and configure options "--with-file-offset-size=32 --with-mem-align=4" with no relief.

[Dovecot] Tricks to running as normal user?
by Ajaxster 15 Dec '04

15 Dec '04

Hi, I'm running on HPUX 11.11 and have installed dovecot 0.99.12 in my home directory. I've been running it at home on FC2 and had no problems. At work, on HPUX, when I modify the dovecot.conf file like is suggested in the wikki <http://wiki.dovecot.org/moin.cgi/Rootless>, it will detach and I can telnet to the port I've chosen, but I don't get any response back after I connect. Not other processes are getting launched when I connect. I can run the libexec/imap and get capability information echoed to the terminal. I tried the test builds and they seem to be hanging during the parsing of the .conf file. The the process never goes into the background. Does anyone have any suggestions on what I could try to get things running? Thanks very much. -- Jay

[Dovecot] Internal login failure
by Jaeson Schultz 15 Dec '04

15 Dec '04

Hello, I am fairly new to Dovecot, so please forgive me if I am missing something obvious here. I have checked the archived dovecot mailing list messages and have Googled for everything I can think of, and I still have not found anything to help me solve this problem. I am running Postfix+Postgresql+Dovecot on my Fedora FC2 box. I have compiled both Postfix and Dovecot from source. I believe I have postfix running properly. No error messages show up in my logs when starting Postfix or Dovecot. Messages are being delivered by Postfix just fine: Dec 12 11:45:42 co-nundrum postfix/virtual[15759]: 15E82F8EF0: to=<jaeson(a)domain.name>, relay=virtual, delay=1, status=sent (delivered to maildir) However, when I try to login to Dovecot over IMAP I get an "Internal login failure" error: [jaeson@localhost jaeson]$ telnet co-nundrum imap Trying 207.7.137.6... Connected to co-nundrum. Escape character is '^]'. * OK dovecot ready. 1 LOGIN jaeson secret 1 OK Logged in. * BYE Internal login failure. Error report written to server log. Connection closed by foreign host. When I check the dovecot log file I see the following entries: dovecot-auth: Dec 12 01:15:59 Info: PGSQL: Performing query: SELECT password FROM user_accounts WHERE username='jaeson' imap-login: Dec 12 01:15:59 Info: Internal login failure: jaeson [66.159.231.21] dovecot: Dec 12 01:15:59 Error: child 9845 (auth) killed with signal 11 Here are the entries from my dovecot.conf file. As you can see, I have set both auth_verbose and auth_debug = yes, but I don't seem to be getting any log messages with enough verbosity to indicate just what the problem is. base_dir = /var/run/dovecot/ protocols = imap imaps pop3 pop3s imap_listen = * pop3_listen = * ssl_parameters_regenerate = 24 disable_plaintext_auth = no log_path = /var/log/dovecot.log info_log_path = /var/log/dovecot.log login_dir = /var/run/dovecot-login login = imap login_executable = /usr/libexec/dovecot/imap-login login_user = dovecot login_process_size = 16 login_process_per_connection = yes login_processes_count = 3 login_max_processes_count = 128 login_max_logging_users = 256 max_mail_processes = 1024 verbose_proctitle = yes verbose_ssl = yes first_valid_uid = 5000 last_valid_uid = 65535 first_valid_gid = 5000 last_valid_gid = 65535 default_mail_env = maildir:/mail/%d/%u mail_save_crlf = yes maildir_copy_with_hardlinks = no maildir_check_content_changes = no mbox_locks = fcntl umask = 0077 imap_executable = /usr/libexec/dovecot/imap imap_process_size = 256 auth = default auth_mechanisms = plain auth_userdb = pgsql /etc/dovecot-pgsql.conf auth_passdb = pgsql /etc/dovecot-pgsql.conf auth_executable = /usr/libexec/dovecot/dovecot-auth auth_user = root auth_count = 1 auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@ auth_verbose = yes auth_debug = yes Additionally, here are the entries in my dovecot-pgsql.conf file: connect = host=localhost dbname=mail_DB user=mailreader password=secret default_pass_scheme = PLAIN password_query = SELECT password FROM user_accounts WHERE username='%u' user_query = SELECT '/mail/'||mailbox AS home, uid, gid FROM user_accounts WHERE username='%u' Finally, here is the configure command I used when building Dovecot from source: ./configure --prefix=/usr --enable-debug --with-pgsql --with-cyrus-sasl2 --with-ssl=openssl --sysconfdir=/etc At this point, I think that the connections to my postgresql tables are all working properly, and the initial authentication with Dovecot appears to be working. Dovecot *does* accept my password and gives me the "OK Logged in." response message, but somewhere before it kicks off the IMAP process it dies with a SIGSEGV. Perhaps I have some file permissions out of whack? Has anyone else encountered this problem, or perhaps has any insight into what might be going wrong or how to find out more information?

That sounds like that's the direction I want to go - I will definitely take a look into that, and possibly tweak it if I can. The way I was thinking about doing it was either respecting one or the other of NO_IMAP or NO_WEBMAIL depending on if you're coming from a local address or a remote one. I might stick with tcpserver using a tcprules.cdb to set environment variables and modify the patch to pass those environment variable(s) onward...we'll see. Or I might just suffer with my many dovecots. > > > I also _think_ I found out the problem, what was corrupting my indexes, > > though I'm not sure.

Yes, unfortunately, the file was unreadable because there was no file system permissions to read it. That actually made dovecot make indices which imply there's nothing in the mailbox. How a file with no FS perms got into my maildir is rather embarassing and I'll skip unless it's important, but it was there and it did hose my indexes.

Hello, I should have sent my first message in plain text instead of HTML so it would show up better in the list archives. Anyhow, I am using the latest release of Dovecot, v0.99.12.1. Seeing as how I don't need the cyrus-sasl2 to be compiled in, I have just rebuilt dovecot without it. Unfortunately I am still getting the same results... [jaeson@shell01 ~]$ telnet co-nundrum imap Trying 207.7.137.6... Connected to co-nundrum. Escape character is '^]'. * OK dovecot ready. 1 LOGIN jaeson secret 1 OK Logged in. * BYE Internal login failure. Error report written to server log. Connection closed by foreign host. The dovecot logs still indicate an "Internal login failure", but offers no extra explanation as to why. dovecot-auth: Dec 13 11:43:04 Info: PGSQL: Performing query: SELECT password FROM user_accounts WHERE username='jaeson' imap-login: Dec 13 11:43:04 Info: Internal login failure: jaeson [216.39.112.19] dovecot: Dec 13 11:43:04 Error: child 25784 (auth) killed with signal 11 I am wondering that since I see the auth_passdb query, shouldn't I also be seeing a log entry for the auth_userdb query as well, or does this happen once the imap process is started? Any advice for how to track down the source of the problem is appreciated. ~Jaeson [This E-mail scanned for viruses]

But I run vpopmail, and I need to make IMAP available only to users who have IMAP 'enabled' (the guys who pay more money). But I need webmail available for _all_ users (even the cheapskates), and my webmail of course uses IMAP behind the scenes. So my solution is one copy of regular Dovecot on port 143, which respects the NO_IMAP flag from vpopmail, and one copy of modified Dovecot, which I patched to ignore the NO_IMAP flag, on port 144 - and then I configured my webmail software to talk to port 144. That copy of Dovecot will eventually only listen to the local network for connections, though currently it listens for anyone. A solution I already tried was having Dovecot run by being invoked from a copy of tcpserver, which used a .cdb 'rules' database which set certain environment variables based upon the users IP address. I patched my copy of Dovecot to listen for those environment variables and pay attention/ignore NO_IMAP based upon those environment variables, but it looks like environment variables get clobbered when dovecot invokes the authenticator process from within imap-login (And the code seems to say that it blows out the environment, too). And I'm willing to bet that it would only work on first invoke of dovecot from imap-login, too, even if it didn't blow out the environment (because the authentication process stays running). All this stuff is, I'm sure, a thousand times easier in something like courier-imap, but I like Dovecot, so I'd rather run two copies of Dovecot than one of courier-imap. So if anyone has any possible direction to go on a solution that lets me run only one Dovecot, I'd love that. Until then, I'm stuck with my hack-ey two-Dovecot solution. I also _think_ I found out the problem, what was corrupting my indexes, though I'm not sure. I think one of the messages in my Maildir was 'unreadable' by Dovecot (well, that's what the logs say). Which seems to completely blow out the index. I got rid of the file, so lets keep fingers crossed that that solves it...

[Dovecot] Problem with LDAP and Dovecot

[Dovecot] Ximian Evolution Issue
by Adam Todorski 13 Dec '04

13 Dec '04

Hi This may be a problem with Dovecot and it may be a problem with Evolution, I'm trying to narrow it down. I'm using Evolution 2.0.2 on Fedora Core 3 x86_64 to connect over SSL to Dovecot 0.99.11 on Debian testing (Sarge) on an i686 using Maildir for the mail store. Specifically, when I open a folder with more than a few dozen messages in it I get the following error (with the carroted fields populated): Error while Opening folder imap://<username>@<mailserver>/<folder>. Incomplete server response: no information provided for message <message number>. Thanks for any leads on this! Adam

[Dovecot] Corrupted index files in 0.99.12.1
by Brady Wetherington 12 Dec '04

12 Dec '04

Hi - I've got two copies of Dovecot installed on my server (don't worry, talking to two different sockets for authentication, with two different sets of filenames using options in configure), and I found at least one instance where the index file for my INBOX (on my own account, in fact) got corrupted. So badly so that when I connected via IMAP and selected my INBOX, it said there were no messages there - but if I logged in via sqWebMail (ugh), it said all my messages were there. Note that it didn't give the 'NO can't use index file' message. I moved the .INBOX directory to another filename, and then re-logged in and found that all was well (it regenerated the index files correctly). Would my old, corrupted index files be of any use to anyone? I still have that directory sitting somewhere. Is it perhaps 'bad' to run two copies of Dovecot? I don't know exactly what I was doing, but I can easily imagine accessing one of my Dovecots using my webmail setup, and one using straight IMAP - is that an unsupported setup? I'd also be happy to discuss why I'm using two copies of Dovecot, but that's a whole other discussion :)

Re: [Dovecot] Timeouts with outlook express
by Daniel 11 Dec '04

Hi Yes I have all the outlook workarounds enabled. Interestingly the progress bar dose not move until the whole email has been downloaded. Normally this moves bit by bit as the mail downloads. But as I said the email is downloading, there is network traffic. Any ideas?

[Dovecot] SQL + AUTH command bug?
by Andrew Hutchings 10 Dec '04

10 Dec '04

Hi, While investigating the problem with Thunderbird auths I found the following happening: Escape character is '^]'. +OK Dovecot ready. CAPA +OK CAPA TOP USER UIDL RESP-CODES PIPELINING SASL PLAIN . AUTH PLAIN + + + -ERR Authentication failed. This is what is happening during a Thunderbird connection, when each '+' happens dovecot does an sql query on the sql server for user '?'. This was asserting mech.c until Timo did the bugfix last night. I currently have dovecot authing via 3 separate sql password tables as it is a migration from 3 old servers. If you try any other auth method (which shouldn't work anyway in my case) it doesn't talk to the SQL servers and just comes back as: -ERR Authentication failed.
