Need help on checkpassword userdb/passdb
by Mark Foley 13 Sep '15

13 Sep '15

I'm experimenting with checkpassword as an auth method for usedb and passdb (http://wiki2.dovecot.org/AuthDatabase/CheckPassword) I've set up the userdb and passdb *exactly* as the wiki suggests as the "standard way": passdb { driver = checkpassword args = /user/util/bin/checkpassword } userdb { driver = prefetch } I've created a checkpassword program that does receive the correct user and password from dovecot. And I am successfully authenticating with ntlm_auth and exiting with status 0. My debug output: AUTHORIZED: (null) USER: (null) userdb_uid: (null) userdb_gid: (null) arg1=/usr/local/libexec/dovecot/checkpassword-reply CMD: /usr/bin/ntlm_auth --username="mark" --password='mypass' ntlm_auth status: 0 Now, the wiki says 2 things that have me stumped: 1. It says that, "Dovecot calls the script with AUTHORIZED=1 environment set when performing a userdb lookup. The script must acknowledge this by changing the environment to AUTHORIZED=2, otherwise the lookup fails." As you can see from my program log, "AUTHORIZED" is not set. Why? Nor are any of the other environment variables mentioned in the wiki. I've listed all the environment variables that *are* passed to the program at the bottom of this message. 2. The wiki says, "Your program received a path to checkpassword-reply binary as the first parameter. Execute it." I did so as a fork() and then execve("/usr/local/libexec/dovecot/checkpassword-reply") How do I know it worked ... or failed? What am I doing wrong?

Dovecot CalDAV server
by Timo Sirainen 11 Sep '15

11 Sep '15

I've been once in a while over the years thinking about implementing CalDAV (and CardDAV) to Dovecot. It might be time to start that soon. Does anyone have any suggestions? So far my main goals would be: - scalable, of course - configurable storage (object storage, regular fs, maybe some key-value dbs, maybe storing as emails) - efficient indexes (potentially using key-value dbs? or maybe just local files. not sure yet what kind of indexing is needed) - have it work with dsync (= replication & migration) Some things I wonder about: - Maybe there is already some code out there that could be used to implement it faster? - Maybe even use something else besides C to implement it.. Then again that makes integration to Dovecot more difficult. - Is anybody interested in helping to develop this? :) I think I still have too much other work that I won't spend a lot of time coding it.. One thing that makes this easier is that Open-Xchange has already implemented a CalDAV server, so they can help to avoid the biggest design mistakes. (There are a couple of reasons why they'd want to replace that.)

My dovecot works fine against Active Directory 2003, but not against AD2008
by Fran 10 Sep '15

10 Sep '15

Hello, my dovecot installation has been working fine against AD till we upgrade from AD 2003 to AD 2008. As http://wiki2.dovecot.org/AuthDatabase/LDAP said, now I'm not able to connect AD through 389 port. The port 3268 works fine though. (...) Sep 7 19:02:05 <dovecotServer> dovecot: imap-login: Error: master(imap): Auth request timed out (received 0/12 bytes) Sep 7 19:02:05 <dovecotServer> dovecot: imap-login: Internal login failure (pid=4846 id=1) (internal failure, 1 successful auths): user=<<username>>, method=PLAIN, rip=<clientLAN_IP>, lip=<dovecotServer_IP>, TLS, session=<T+grMCsfqgAKHyZV> (...) Sep 7 19:02:06 <dovecotServer> dovecot: auth: Error: ldap(<username>,<clientLAN_IP>,<ZjyONSsf6QAKHyZV>): Connection appears to be hanging, reconnecting Sep 7 19:02:06 <dovecotServer> dovecot: auth: Error: ldap(<username>,<clientLAN_IP>,<T+grMCsfqgAKHyZV>): LDAP search returned multiple entries (...) Is there a technical reason for this problem? Does it exist any workaround? The use of Global Catalog (port 3268) is not a solution for me, since it misses many attributes. (ex. I use the field "initials" to set the quota and this field is not available through port 3268). I also noticed that, now, it uses any DC available in the domain, it doesn't care what I configured in "hosts = " parameter. This is using "hosts = dc03.domain:389": ----------------------------------------------- [root@<dovecotServer> ~]# netstat -anp | grep dovecot | grep auth tcp 22 0 <dovecotServer_IP>:55217 <dc03.domain_IP>:389 ESTABLISHED 4872/dovecot/auth tcp 22 0 <dovecotServer_IP>:57645 <dc06.domain_IP>:389 ESTABLISHED 4872/dovecot/auth tcp 0 0 <dovecotServer_IP>:55216 <dc03.domain_IP>:389 ESTABLISHED 4872/dovecot/auth It looks like it does a look up for other domains controller (I don't know how nor why) and it connect aleatory to any DC in my domain (in this case dc06.domain, but it changes any time), additionally to the configured one (dc03.domain). This is using "hosts = dc03.domain:3268": ------------------------------------------------ [root@<dovecotServer> ~]# netstat -anp | grep dovecot | grep auth tcp 0 0 <dovecotServer_IP>:58485

Convert from Maildir to Mdbox
by J. Echter 09 Sep '15

09 Sep '15

Hi, i'd like to convert from maildir to mdbox. what would be the best way to do this? i have read the dsync part of the dovecot wiki but i don't get what i have to use for my setup. my dovecot.conf (the snippets i think would matter): mail_gid = 5000 mail_home = /DATEN/vmail/%d/%n mail_location = maildir:/DATEN/vmail/%d/%n/mail/ mail_plugins = " zlib" mail_uid = 5000 Thanks for your input.

[Dovecot] dsync replication errors
by Oli Schacher 09 Sep '15

09 Sep '15

Hi I'm trying to build a cluster of two servers with dsync replication (based on http://wiki2.dovecot.org/Replication) My test setup works fine for very simple tests, I can log in to both servers, copy a message to one of the servers and it successfully apperars in the other account. But, if I try to copy a large amount of messages at once to one of the accounts, my maillogs get flodded with errors(see below) and the mailboxes seem to get out of sync and messages are duplicated over and over again (I originally copied 100 messages and ended up with thousands in both mailboxes until I killed dovecot) I'd appreciate if someone could have a look at my config and tell me what I did wrong. dovecot.conf of both servers, they are identical except for the target ip in mail_replica: dovecot -n # 2.2.beta1 (070ca24e5846+): /etc/dovecot/dovecot.conf # OS: Linux

sieve_extprograms - double linebreaks at filtering
by Hajo Locke 09 Sep '15

09 Sep '15

Hello List, i have a problem when using sieve-plugin sieve_extprograms. I use dovecot 2.2.18 and bundled pigeonhole 0.4.6 (Ubuntu 14.04.3 LTS) i have enabled sieve_extprograms and vnd.dovecot.filter to send mail to user-defined script and get changed content back. My script previously was used with procmail and is working fine. Using same script with vnd.dovecot.filter leads to odd behavior. I already found out the problem itself: By sending Mailcontent to filter-programm it seems that sieve/sieve_extprograms is adding additional linebreaks to every line of complete mail. Please see this image to clarify: http://r31i.imgup.net/header8d56.jpg?l=de Every lineending got additional windows-lineendings, which leads to problems with processing scripts. Piping mails by procmail to same script is working without problems, because this mails are recieved "clean" without the "^M". this is part of dovecot.conf: plugin { sieve = ~/.dovecot.sieve sieve_plugins = sieve_extprograms sieve_extensions = +vnd.dovecot.pipe +vnd.dovecot.filter +vnd.dovecot.execute sieve_pipe_bin_dir = /usr/local/bin/ sieve_filter_bin_dir = /usr/local/bin/ } this is part of userscript ~/.dovecot.sieve: require ["fileinto", "vacation", "variables", "envelope", "imap4flags", "vnd.dovecot.filter", "subaddress"]; if address "to" "test2(a)example.com" { filter "my-script"; } my-script currently just recieves and saves raw-data, so i could find difference between sieve and procmail mails. What to do here? Is this a kind of bug of sieve/sieve_extprograms or i have to use additional parameters? Thanks, Hajo
