[Dovecot] dovecot ssl problem
by Alexander Heuer 20 Apr '05

20 Apr '05

Hi there, I am having a weird problem with dovecot and ssl. If I am accessing the dovecot imap server with for example sylpheed-claws or evolution, everything works fine. If it is accessed via windows either by outlook or thunderbird, we get occassional timeouts. It's working fine for a few hours, then for 5 to 20 minutes, every attempt to connect from the outside results in "Connection to server timed out". Added to that, the problem only arises, if a direct SSL connection to Port 993 is used. Using Sylpheed with STARTTLS to Port 143 from the outside works fine as well. It's not a firewall Problem, since port 993 and 143 are open, the config files have been checked over and over for 2 weeks and are good as well. Dovecot log says: imap-login: Apr 20 13:26:05 Warning: SSL_read() syscall failed: Connection timed out [83.104.224.142] Doing uber verbose output doesn't bring up any extended information, syslog stays clean as well. The Problem is not directly reproducable by a certain action, it just arises from time to time. There can be 3 working days without problems, or 6 timeouts > 20 minutes within one day. System is Debian Sarge unstable with a custom 2.6.10 Kernel. During the timeouts, mail is still received and put into the users mailboxes by exim, it's just that you cannot access the imap server for approx 20 minutes. Dovecot version is 0.99.14 Regards Alexander Heuer

Hi, I have some problems with my connection from outside to POP3/IMAP... As far as I can see every should be set corret. Currently I use version 0.99.11-1.FC3.4 installed from an RPM-file. I tried to debug the signin process. It's always saying bad password... What encryption can DoveCot read? Currently my password is encrypted with md5crypt... Regards Anders

[Dovecot] dovecot-sasl license
by Marcus Rueckert 19 Apr '05

19 Apr '05

hi, i talked to timo about re-licensing the sasl part of dovecot under a more liberal license (bsd/lgpl e.g.). it would allow the integration of it in bsd base systems. another reason i would be interested is adding sasl support to svnserve [1]. so here is my question: what is your oppinion about this issue? any objections from contributors? darix [1] http://subversion.tigris.org/ -- irssi - the client of the smart and beautiful people http://www.irssi.de/

18 Apr '05

Hi, I have a small personal server here which I've managed to successfuly install the dovecot server onto. What i'm hoping to do is download POP3 mail from 1 or 2 accounts using the dovecot server so I'll be able to read all from the dovecot server... Is this possible? thanks! Eurig

[Dovecot] attr_names in test67
by Thomas Hummel 18 Apr '05

18 Apr '05

Hello, I'm wondering if the following situation is valid (though I think it isn't since I still cannot authenticate with ldap pass/userdb on test67 running on FreeBSD-5.3). Is it normal that the passdb_ldap_conn->attr_names second element (for instance) "turns to" "homeDirectory" as the following step by step gdb run sample shows ? : -- Breakpoint 1, userdb_ldap_preinit (args=0x80796d0 "/usr/local/dovecot/etc/dovecot-ldap.conf") at userdb-ldap.c:201 201 userdb_ldap_conn = db_ldap_init(args); (gdb) p passdb_ldap_conn->attr_names[1] $1 = 0x8079990 "userPassword" (gdb) cont Continuing.

[Dovecot] SORT using cached filesystem modtimes
by Emmett Lazich 18 Apr '05

18 Apr '05

Timo or anyone, This may be a bug or maybe a design decision. Either way I am curious to hear comments. Why do the dovecot-0.99.14 server's .imap.index files contain a cached copy of each message's date and time as supplied by the filesystem, as opposed to the date and time found in each message header? When testing various imap clients (eg. tbird-1.0.2, evolution-2.0, outlook2003, squirrelmail-1.4.4) I was intrigued by the behaviour of message date sorting. I toggled on/off the use of server side SORTing in some imap clients, then started forcing rebuilds of .map.index files, and eventually came to the above conclusion. For normal dovecot server side processing, this condition (if I am correct) may not be a problem, but if someone was to deposit a bunch of maildir files firstly into an imap account (bypassing dovecot), and if this person (eg. me) did not preserve the filesystem/inode file attributes. Then dovecot appears to cache the "wrong" data. What happens then is that some imap clients can display wrong date+times in the message lists, and some imap clients find that server side SORTing does not work. Keen to hear thoughts/opinions. -Emmett

[Dovecot] LSUB matches prefix bug?
by Chris Wakelin 17 Apr '05

17 Apr '05

I think I've found a minor bug in the LSUB command: . LSUB "" "*" gives ... * LIST (\Noselect) "/" "#maildir" ^^^^ * LSUB () "/" "#maildir/test4" where I have a namespace with prefix "#maildir/". Here's a patch to make it not list the namespace prefix in an LSUB command (or should it list it as 'LSUB (\Noselect) "/" "#maildir"'?) :- --- dovecot-1.0-stable.orig/src/imap/cmd-list.c Fri Mar 18 20:00:44 2005 +++ dovecot-1.0-stable/src/imap/cmd-list.c Mon Apr 11 18:29:33 2005 @@ -218,7 +218,7 @@ match = ns->hidden ?

[Dovecot] Dovecot causing hanging on random folders...
by Rick Flower 17 Apr '05

17 Apr '05

I've been using the 1.0 test series (currently 1.0test 67 and before that 1.0-test59) and both exhibited this issue.. I use Thunderbird and will open one or two of my nested Maildir folders via imap and find that it goes out there trying to open the folder (according to the messages that Thunderbird claims) and it never comes back.. I've attached to the various dovecot processes to see what their doing and they appear to be waiting for things to do -- e.g. not working on anything in particular.. The only way to fix this is to quit Thunderbird and restart it.. I see this about 2-3 times a day.. I'd love to track it down.. I've seen this on Fedora Core 1 (i386 server) and also on a PPC Linux system running an older kernel (on a Buffalo Linkstation if you know what that is).. Below is the current set of dovecot processes running on my FC1 box : [rickf@srv1 dovecot-1.0-test67]# ps aux | grep dove root 748 0.0 0.0 3380 720 ? S 11:30 0:00 dovecot-auth dovecot 749 0.0 0.0 2440 668 ? S 11:30 0:01 imap-login dovecot 760 0.0 0.0 2788 700 ? S 11:30 0:01 imap-login root 709 0.0 0.0 2312 688 ? S 11:30 0:13 /usr/dovecot/sbin/dovecot I'd be happy to track this down if someone can point me in the right direction.. -- Rick

[Dovecot] Multiple auth mechinisms
by Micha Silver 17 Apr '05

17 Apr '05

From the WIki features page, ( http://wiki.dovecot.org/moin.cgi/CoreFeatures ) it's not clear to me if the dovecot-stable release supports multiple authentications mechanisms (like in 1.0-testxx). I need both virtual domains and system users. Can I use the stable release for this? Thanks, --Micha
