[Dovecot] GSS/Kerb5, Solaris 10, how to build?
by Jeff A. Earickson 06 Apr '07

06 Apr '07

Gang, I've been trying to build rc29 under Solaris 10 using either "--with-gssapi" or Kerberos 5 ticket usage. I'm trying to figure out how to set up fetchmail on another S10 box to do IMAP fetches from dovecot without having to enter a password. No matter what configure option I try, I get Building with GSSAPI support ........ : no at the end of the configure. I searched the list archives and I see some discussion from Dan Price about Solaris 11 builds. Is gssapi supposed to work with Solaris 10? Advice please? My dovecot server is a Kerberos 5 client of Active Directory, with PAM configured to do TGT exchanges. I can login to the system with my AD password, ssh to other Kerb clients without having to type in passwords -- Kerberos works at the OS level. Jeff Earickson Colby College

[Dovecot] changing fs separator for maildir (suggestions?)
by Justin McAleer 05 Apr '07

05 Apr '07

Since we're migrating from an existing system that allows periods in folder names, I believe we must continue to allow them. So, I am deciding what to use as the separator instead. Right now, I'm leaning towards the backtick (`), since I don't think I have ever used it unless I was trying to execute an external command in some code. So, can anybody think of reasons not to use it, or have a better idea?

Re: [Dovecot] Problems using GFS2 and clustered dovecot

Well, I'm not paying for it. And I've managed to fix the comedy stability I've come across so far, but you're right- I haven't really loaded the system up yet. My rationale is that I want a filesystem I can share between several servers, reducing the points of failure as far as I can down. We've got a large iSCSI SAN we've already bought for other projects, and I'd like to use that for our storage. So using NFS, I'd have to have another server in front of my SAN that act as an NFS server (presuambly as a single point of failuire), and the mail servers as NFS clients. I'd rather have the servers talk to the SAN directly. Besides, NFS never really works for me, but I'm sure I could overcome that. Anyway, I don't think it's a GFS problem so far.

Re: [Dovecot] compiling dovecot on aix gcc 3.3.2
by Ralf Becker 05 Apr '07

Hello funkypunky drunky, on AIX dovecot plugins (which are shared objects = .so) are a little bit problematic. It is not enough to activate run time linking by using -brtl and make the main program (dovecot) to be able to use shared objects. When a share object does function calls back into the main program, all these functions (=symbols) in dovecot have to be explicitly exported. Otherwise you see "signal 11" or so. Because this is very fiddly, there is a linker flag -bexpall to export all symbols of the main program (dovecot)... but this does seemingly not work with symbols defined in static libraries (.a). While dovecot build creates static libraries to keep the linker command line small, but does *not* generate export files (.exp) containing the libraries globals symbols, the compile time linker does not known anything about them. I think, if dovecot build would use libtool to create the libraries, libtool would export the libraries symbols to fix this. And this is, what my script does. It looks on the compiler command line for library file (.a) and exports all global symbols to an .exp file. The paths of these .exp files are appended to the original compiler command line and so -bexpall knows about the globale symbols defined in the libraries and is able to export them. I don't know if this information is useful for you, because you're using gcc. But if you are using AIX ld (instead of gnu ld) you have to deal with this problem, I think.

05 Apr '07

http://dovecot.org/releases/dovecot-1.0.rc29.tar.gz http://dovecot.org/releases/dovecot-1.0.rc29.tar.gz.sig Probably one more RC after this. * Security fix: If zlib plugin was loaded, it was possible to open gzipped mbox files outside the user's mail directory. + Added auth_gssapi_hostname setting. - IMAP: LIST "" "" didn't return anything if there didn't exist a namespace with empty prefix. This broke some clients. - If Dovecot is tried to be started when it's already running, don't delete existing auth sockets and break the running Dovecot - If deliver failed too early it still returned exit code 89 instead of EX_TEMPFAIL. - deliver: INBOX fallbacking with -n parameter wasn't working. - passdb passwd and shadow couldn't be used as master or deny databases - IDLE: inotify didn't notice changes in mbox file - If index file directory couldn't be created, disable indexes instead of failing to open the mailbox. - Several other minor fixes

[Dovecot] *****SPAM***** The folder 'Inbox' cannot contain items. Namespace problems
by Francisco Reyes 05 Apr '07

05 Apr '07

Several attempts to support both Mac and PCs keep failing. In my latest attempt I used the following settings: #courier-imap compatibility/Thunderbird namespace private { separator = . prefix = INBOX. inbox = yes } For MAC OS Mail.app namespace private { separator = / prefix = INBOX/ inbox = no hidden= yes } This last attempt was based on the suggestion of Timo Sirainen, on the Mac settings. The PC settings were the defaults I got from the sample config and have always worked for PC clients. The new setup with namespace private worked for Mac clients, but got the following error for a number of users in both Outlook and thunderbird. Unable to display the folder. The folder 'Inbox' cannot contain items. This is most likely a limitation of your IMAP server. In order to create a folder that can contain items, be sure to append / to its name as you create it. I see this is an old issue. http://groups.google.com/group/microsoft.public.outlook/browse_thread/thread /5f990142171fb792/62adb6c069946e40?lnk=st&q=%22cannot+contain+items%22+dovec ot&rnum=1#62adb6c069946e40 One interesting point we discovered was that if we set an IMAP account in Outlook the very first time we logged in, it worked. If we closed the client, all subsequent times the "folder Inbox cannont contain items" error would come up. doing a TCPdump showed us that the difference was that the first time that Outlook connects it issued a "Select" command, but all other times it did not. Someone suggested to take out prefix = INBOX. Would that help? I don't want to cause problems for the vast majority of our PC users while trying to fix the Mac clients. Even though Mac users are a minority of our users, it is extremely problematic for us not to be able to support them because many domains may have a handfull of such clients.. so we basically will not be able to host a large number of domains in dovecot machines, just because of a handfull of Mac clients. Currently using Dovecot r27, but have been having this same problem since r15.

[Dovecot] Login lockups
by Daniel L. Miller 04 Apr '07

04 Apr '07

When dovecot works - it works great, and I thank you. But it seems like every time I setup a new server, it's a challenge getting the IMAP logins to work reliably. The changelog's top comment is stamped 2007-01-05, 18:48 if that helps nail down the version (I'm using a Debian/Ubuntu package). Both non-SSL and SSL logins have the problem. This time around I'm using LDAP authentication - and once I figured out how it worked beautifully. The problem is from time to time - with no particular consistency - I lose the ability to log in. A "telnet localhost 143" on the server works with a Dovecot response, then followed with a "01 LOGIN <user> <password>" results in a long delay, then a timeout, with no log files affected. What can I provide to try to trace this? protocols = imap imaps disable_plaintext_auth = no login_process_per_connection = yes -- Daniel

[Dovecot] logfile consistency
by David Lee 04 Apr '07

04 Apr '07

We do some routine logfile (syslog) gathering and analysis. I've been looking at extending this to parse the syslog output of dovecot. Hmmm... Ignoring the leading 'date hostname' prefix, some sample lines are: dovecot: imap-login: Login: user=<uuuuuu>, method=PLAIN, rip=dd.dd.dd.dd, lip=dd.dd.dd.dd dovecot: IMAP(uuuuuu): Disconnected: Logged out dovecot: IMAP(uuuuuu): Disconnected in IDLE dovecot: imap-login: Aborted login: rip=dd.dd.dd.dd, lip=dd.dd.dd.dd dovecot: pop3-login: Login: user=<uuuuuu>, method=PLAIN, rip=dd.dd.dd.dd1, lip=dd.dd.dd.dd dovecot: POP3(uuuuuu): Disconnected: Logged out top=0/0, retr=0/0, del=0/8, size=194970 dovecot: pop3-login: Aborted login: rip=dd.dd.dd.dd, lip=dd.dd.dd.dd deliver(uuuuuu): msgid=<014089712.74355909944644(a)thhebat.net>: saved mail to INBOX I've obfuscated some of the local detail: uuuuuuu represents a username/identifier; dd.dd.dd.dd represents an IP address. Would it be possible, please, to consider improving the consistency of the logging information? For instance: 1. All lines, including the "deliver", to begin "dovecot:"; 2. The "IMAP(uuuu): Disconnected" to become "imap: disconnected user=<uuuu>"; Overall this would make it more consistently amenable to perl-like pattern processing, at least with a reasonably hierarchical structure to the messages. Perhaps something like: dovecot: subprogram: event, key1=value1, key2=value2 ... where: "subprogram" is "{imap,pop,deliver,...}"; "event" is "{login,disconnected, ...}; and one of the "key=value" will usually be "user=<uuuu>". That would really make post-processing of logging information (whether offline, or 'live' via piped syslog) considerably easier. Thanks. -- : David Lee I.T.

[Dovecot] How to integrate dspam and dovecot
by Manilal K M 03 Apr '07

03 Apr '07

Hello all, I am currently setting up a new mail server with Qmail, OpenLDAP and Dovecot in CentOS-4.4. Qmail version is 1.03, OpenLDAP is 2.3 and Dovecot version is dovecot-1.0-3_50.rc27(RPM). I have successfully installed and tested it. But I have two issues with the current setup: #1. I am using dovecot LDA and configured the OpenLDAP such that the mail be delivered to the virtual users through a script. This script is saved in /var/qmail/bin/deliver.sh and the contents is as follows: /usr/bin/dspam --stdout --mode=tum --deliver=innocent,spam --feature=chained,noise --user global |/var/qmail/bin/preline -f /usr/libexec/dovecot/deliver -d $RECIPIENT || exit 77 This script name is mentioned in each user's deliveryProgramPath in the LDAP. I am not sure whether this is the best approach of using dovecot as MDA. I tried to include the following contents in /var/qmail/control/defaultdelivery : |/var/qmail/bin/preline -f /usr/libexec/dovecot/deliver -d $RECIPIENT But it seems that this is not working as desired. Please comment, if I have gone wrong anywhere. #2: I wish to use dspam to filter out the spam messages, but I am unsure whether the dspam plugin mentioned in http://johannes.sipsolutions.net/Projects/dovecot-dspam-integration is already in the dspam version I am using. If it's available please give details to configure it. Kindly share ideas. regards Manilal. -- Better to light one candle than to curse the darkness.

[Dovecot] No CA names sent in TLS handshake
by Johnny Chadda 03 Apr '07

03 Apr '07

Hello, I'm setting up Dovecot with client certificates and everything is working fine as long as the client only has one certificate in his store. If he has more than one, the wrong one might be sent to the server. The root of the problem is that Dovecot does not send out a list of valid CA names in the TLS handshake. If I connect using openssl s_client I get: "No client certificate CA names sent" I am using Dovecot 1.0 RC15 from backports.org. Is there a solution to this problem? Regards, Johnny

[Dovecot] Init.d boot scripts??
by rodman＠thefrowerts.com 03 Apr '07

03 Apr '07

Hello, Trying to figure out how to get dovecot to startup at boot. I saw the Ubuntu script on the dovecot site, but that didn't work on my system (SuSe 10.2). Of course, copying the /usr/local/sbin/dovecot file into /etc/init.d doesn't work at all. Any one have working SuSe script?? Rodman

[Dovecot] *****SPAM***** Upgrading from rc27 to rc29?
by Francisco Reyes 03 Apr '07

03 Apr '07

After sending a messasge about a problem (The folder 'Inbox' cannot contain items. Namespace problems) I found what seems to be a fix in the release for rc29. Besides any potential configuration files, do I need to delete the old index files? Any of the dovecot files? Based on the release notes for rc29 it seems the following will fix the problem we are experiencing: IMAP: LIST "" "" didn't return anything if there didn't exist a namespace with empty prefix. This broke some clients.

[Dovecot] [PATCH] to fix 2 pam issues
by Phil Oleson 03 Apr '07

03 Apr '07

Timo, I finally made the time to backport a pam fix I created for proftpd over to dovecot, that allows FreeBSD's pam_group to work as expected. (the bug was escalated to me internally hehe.. ). I also noticed an issue while testing that will be confusing to users. If the docs stay as is, or the other half of this patch is applied, then when the dovecot.conf contains: passdb pam { args = * } the imap files within etc/pam.d right now have to be named 'IMAP' and 'POP3' rather than the expected 'imap' and 'pop3'. The attached patch fixes the code to match the docs. -Phil. --- src/auth/passdb-pam.c.orig Mon Mar 26 10:10:26 2007 +++ src/auth/passdb-pam.c Mon Apr 2 16:18:54 2007 @@ -275,6 +275,8 @@ (void)pam_set_item(pamh, PAM_RHOST, host); /* TTY is needed by eg. pam_access module */ (void)pam_set_item(pamh, PAM_TTY, "dovecot"); + /* FreeBSD's pam_group need this set as well */ + (void)pam_set_item(pamh, PAM_RUSER, request->user); status = pam_auth(request, pamh, &str); if ((status2 = pam_end(pamh, status)) == PAM_SUCCESS) { @@ -428,8 +430,15 @@ int fd[2]; pid_t pid; - service = module->service_name != NULL ? - module->service_name : request->service; + if (module->service_name != NULL) { + service = module->service_name; + } else { + if (!strncmp(request->service, "IMAP", strlen(request->service))) + service = "imap"; + else if (!strncmp(request->service, "POP3", strlen(request->service))) + service = "pop3"; + } + auth_request_log_debug(request, "pam", "lookup service=%s", service); if (worker) {

[Dovecot] Suggestion: mod_auth_dovecot
by David Anderson 03 Apr '07

03 Apr '07

Hello, I have a suggestion which might be a small and very useful project for a C coder (I'm not one!). As Dovecot makes its authentication interface available to other programs, I think that an Apache module to use it would be very useful. Currently I share an passwd-db file between Dovecot and Apache. However with Apache that means I have to give Apache read access. That means that websites with PHP could read that password file if they liked. If Apache could talk to the Dovecot authentication process instead, that would be a lot better. I'm sure there are lots of situations in which this would be useful - Dovecot's authentication settings are so flexible that it would be very handy to be able to use them more widely. If anyone produces one, I pledge to produce an RPM package and submit it to Fedora as my contribution. I would do it myself if I knew C... David

[Dovecot] prefetch + static + deliver
by Tom Bombadil 02 Apr '07

02 Apr '07

Hi all... The prefetch entry in the wiki says: "If you're using Dovecot's local delivery agent, you'll still need a valid userdb which it can use to locate the users. You can do this by adding a normal sql/ldap userdb after userdb prefetch." (http://wiki.dovecot.org/UserDatabase/Prefetch) My question is: Does it need to be a SQL/LDAP userdb? How about static or passwd? Thanks in advance :)

[Dovecot] testing LDAP connections
by Hugo Monteiro 02 Apr '07

02 Apr '07

Hello all, I haven't looked into the source code, but i suspect that LDAP connections, once established, are not tested properly. My scenario is the followind: Dovecot server <--------> firewall <---------> LDAP backend What happens is that the firewall has a security feature which basically make de firewall box "forget" about connections that are idle for more than X period of time. That particular setting is 30 minutes right now. When that happens, neither the LDAP backend or the Dovecot server get any type of notification, and for all they care the connection is alive and well. This is a very common implementation in firewalls nowadays. So my question is, is there any way to make dovecot re-open a new connection if there is a timeout while trying to use a connection already opened? I believe that this could be of great benefit for those who don't have their servers on the same physical network.

[Dovecot] Using Dovecot LDA with Sendmail
by Scott Peron 02 Apr '07

02 Apr '07

Hi all, After looking at the LDA/Sendmail page in the dovecot wiki, I wanted to contribute another method to easily configure Sendmail to use deliver. Instead of adding a new mailer definition, as already suggested, one can simply use the following line in their sendmail.mc file instead: FEATURE(`local_procmail', `/usr/libexec/dovecot/deliver', `deliver -d $u', `SPhnu9')dnl And further on, still use: MAILER(procmail)dnl The location of deliver will of course vary for each OS and distro, etc, but this redefines the "procmail" mailer in the resulting sendmail.cf to use deliver instead, with the correct flags. For most setups, I believe this is the simplest configuration path.
