[Dovecot] dovecot won't compile for GnuTLS
by Kristoffer Bylund 10 Apr '06

10 Apr '06

Hi! I'm currently investigating a switch from courier-imap to dovecot since a number of our users experience problems with Outlook in combination with SSL. I can compile dovecot with openssl support and it runs "fine" except that the Outlook issues are still there. I read that dovecot works best with GnuTLS and thought that I'd try to compile for that instead. The system is running SuSE 9.3. I've installed the gnutls-library and configure runs fine, but make stops. My configure arguments is ./configure --with-vpopmail --with-ssl=gnutls Make stops with the following info: make[3]: Entering directory `/usr/src/qmail/dovecot-beta-test/dovecot-1.0.beta5/src/master' /bin/sh ../../libtool --tag=CC --mode=link gcc -std=gnu99 -g -O2 -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -o ssl-build-param ssl-init-main.o ssl-init-openssl.o ssl-init-gnutls.o ../lib/liblib.a -lgnutls -lgcrypt gcc -std=gnu99 -g -O2 -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -o ssl-build-param ssl-init-main.o ssl-init-openssl.o ssl-init-gnutls.o ../lib/liblib.a -lgnutls -lgcrypt ssl-init-gnutls.o(.text+0x93): In function `_ssl_generate_parameters': /usr/src/qmail/dovecot-beta-test/dovecot-1.0.beta5/src/master/ssl-init-gnutl s.c:34: undefined reference to `gnutls_dh_params_generate' ssl-init-gnutls.o(.text+0x11d):/usr/src/qmail/dovecot-beta-test/dovecot-1.0. beta5/src/master/ssl-init-gnutls.c:57: undefined reference to `gnutls_rsa_params_generate' collect2: ld returned 1 exit status make[3]: *** [ssl-build-param] Error 1 make[3]: Leaving directory `/usr/src/qmail/dovecot-beta-test/dovecot-1.0.beta5/src/master' make[2]: *** [all-recursive] Error 1 make[2]: Leaving directory `/usr/src/qmail/dovecot-beta-test/dovecot-1.0.beta5/src' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/usr/src/qmail/dovecot-beta-test/dovecot-1.0.beta5' make: *** [all] Error 2 Any clues?

[Dovecot] consistency issue
by Catalin Constantin 09 Apr '06

09 Apr '06

Hi there, We have our mail boxes stored on a NFS server and we use maildir for mailbox storage. Some days ago we had a crush and SOME of the mailboxes get an error on QUERY: "EXPUNGE". eg: telnet localhost 143 Trying 127.0.0.1... Connected to localhost.localdomain. Escape character is '^]'. * OK Cabanova Mail ready. A01 LOGIN "hoeschen(a)***.com" "***" A01 OK Logged in. A01 STATUS "INBOX" (MESSAGES UNSEEN RECENT) * STATUS "INBOX" (MESSAGES 6 RECENT 5 UNSEEN 5) A01 OK Status completed. a01 SELECT "INBOX" * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 6 EXISTS * 5 RECENT * OK [UIDVALIDITY 1143550926] UIDs valid * OK [UIDNEXT 40] Predicted next UID a01 OK [READ-WRITE] Select completed. a01 EXPUNGE * BYE Mailbox is in inconsistent state, please relogin. Connection closed by foreign host. The issue i think it is related to the dovecot dovecot.* files located in the user home. After i delete thoes it works again ! Any clue how this can be solved by not manually deleting the dovecot.* files (index files) ? Thank you for your time ! -- Catalin Constantin Bounce Software http://www.bounce-software.com http://www.cabanova.ro

[Dovecot] Filesystem quota
by Stian Jordet 09 Apr '06

09 Apr '06

Hi, I've seen you commited a lot of quota work tonight. I'm still unable to get the filesystem quota working, and I wonder if it's just me that is stupid, or if theres a bug somewhere. I enable quota and imap_quota plugins, I set fs in my ldap-base for quota, and logons. I then get this: dovecot: imap(ingvild): fs quota add storage dir = /home/ingvild/Maildir dovecot: imap(ingvild): fs quota: mount path for /home/ingvild/Maildir not found from /etc/mtab In my logs... Anyone knows the problem? Best regards, Stian

[Dovecot] ssl-parameters.dat ownership problems on MacOS X
by Lars Skovgaard 09 Apr '06

09 Apr '06

Hi all, I've been having some issues with the ssl-parameters.dat file from dovecot 1.0 beta 2 on MacOS X 10.4.6 client. As I understand it, the user/group on the file should be root:wheel, and I have changed ownership accordingly. However, on occation this gets set to root:dovecot by some process I haven't yet identified, which causes the ssl-parameters.dat file to be regenerated once every 10 minutes instead of the default. Does anyone have an idea what is going on, or how I can avoid this? Best, Lars

[Dovecot] Feature Request: Config Dump
by Charles Marcus 09 Apr '06

09 Apr '06

Hello, One of the less friendly lists I am on is the Postfix list, but one of the features that Postfix has, and the use of which is required when asking for help on their list, is a command called 'postconf', which simply dumps the current configuration parameters into a neat, orderly output that you can then cut-n-paste into an email request for help. The postfix guys won't even try to address a problem without this output (as opposed to snippets from config files), combined with log snippets of the failing behavior (as opposed to bounced message text, or 'it don't work' comments). So, what I'd like to see is something similar - a command that I can issue that will cause Dovecot to dump all of the configuration parameters it is currently using in a neat, orderly arrangement. This would dramatically help individual users in troubleshooting their own problems, as well as help people on this list help others. It would totally eliminate all of the 'what is xys set to' questions back and forth. But I'm more interested in how it will simply help me to see how I have it configured, and allow me to easily spot conflicting or misconfigured parameters. -- Best regards, Charles

[Dovecot] dovecot NTLM authentication
by Lior Okman 09 Apr '06

09 Apr '06

Hi, I'm trying to configure DoveCot to allow NTLM authentication. I've successfully authenticated with Outlook 2003 against Dovecot when the passdb backend used to store the password is a passwd-file. It doesn't matter if the passwd-file contains plain or NTLM encrypted passwords. When I compare the NTLM hash provided by the dovecotpw utility to the one I have in my SAMBA ldap, it appears to be exactly the same. When I use the LDAP passdb backend, I can see in the log file that dovecot has received the correct NTLM hash value, but outlook fails to authenticate successfully. I'm using the debianized dovecot version v1.0.beta2. I can post my dovecot-ldap.conf file, if it will help. Can anybody help me configure my dovecot to allow Outlook to perform NTLM authentication when the password database is in LDAP? Thanks, Lior Okman

[Dovecot] Digest-MD5 authentication problems
by Trev Peterson 09 Apr '06

09 Apr '06

Hello, I have dovecot setup to pull passwords stored in plain from a database. My allowed authentication mechanisms are cram-md5 and digest-md5. Cram works but digest fails on my evolution client with and authentication failed. The server is running dovecot 0.99.14-1 on debian sarge. The user logging in is test(a)advanced-reality.com. Some potentially relevant portions of dovecot.conf are: auth_mechanisms = digest-md5 cram-md5 auth_default_realm = auth_user = dovecot-auth >From the logs with auth_verbose = yes and auth_debug = yes in dovecot.conf: Mar 16 08:12:51 localhost dovecot-auth: PGSQL: Performing query: SELECT password FROM mailbox WHERE username = 'test' AND domain = 'advanced-reality.com' AND active IS TRUE Mar 16 08:12:51 localhost dovecot-auth: digest-md5(test(a)advanced-reality.com): password mismatch Mar 16 08:12:51 localhost pop3-login: Aborted login [64.81.224.97] Some preliminary searching led me to this: http://www.dovecot.org/list/dovecot/2003-November/002598.html Is there a problem with digest-md5 in this version of dovecot? Any pointers on how to troubleshoot this further? Any additional help is appreciated. Let me know if additional information is needed. Thanks -- Trev Peterson <trev(a)advanced-reality.com> Advanced Reality

[Dovecot] TCP wrappers patch
by Timo Sirainen 09 Apr '06

09 Apr '06

I finally started looking into how to use libwrap, and even got the code working: http://dovecot.org/patches/1.0/tcp-wrappers.patch However once everything was done, I realized it can't work that way because login processes are normally chrooted. So if you want TCP wrappers and don't care that much about the security given by chrooting, you could disable it and use the above patch. Alternatively you could just make sure that the hosts.allow/deny files are always copied inside the chroot. I think I'll just forget about TCP wrappers for now, and implement it in Dovecot 2.0 as some separate non-chrooted process.

[Dovecot] How to achieve: Automove of mails
by Daniel Watts 09 Apr '06

09 Apr '06

Dear All, I was wondering if this is possible: I am using namespaces to support my environment which has legacy mboxes and new maildirs. In it looks like: namespace private { separator = / inbox = yes prefix = location = maildir:/home/virtual/%d/home/%n/Maildir/ } namespace private { separator = / prefix = mail2/ inbox = yes hidden = yes location = mbox:/home/virtual/%d/home/var/spool/mail/%n:INBOX=/home/virtual/%d/var/spool/mail/%n } This basically means that there is a hidden inbox "mail2/INBOX" that the user cannot see but which can referenced and accessed. What I would like is for Dovecot to automatically move all mail (actually only as much as possible within quota limits) in "mail2/INBOX" into "/INBOX" whenever INBOX is checked/expunged. An alternative acceptable solution is to have something that moves mail once it has read. I would then symlink mail2/INBOX as a "New mail" folder. Once user's read their mail it is moved to the standard /INBOX folder. Are either of the above possible natively or do I need to look at something like plugins? Incidently where is the documentation guiding plugin development? I've looked at the website but can't find anything either by browsing or searching. Many thanks, Daniel
