[Dovecot] IMAP EXPUNGE disconnect/box hang - Fedora Core 2, Squirrelmail and Evolution
by Schettino, John Charles 22 Apr '05

22 Apr '05

I'm a bit befuddled by this behavior. I've been using dovecot for close to a year, and recently the Fedora Core 2 Update: dovecot-0.99.13-4.FC2 build came in via yum. Since then I occasionally get this EXPUNGE disconnect error. When the error hits, the box does not crash but I can no longer log in*, nor start any new processes. I happen to have gkrellm running and I see a slow but steady climb in the # of processess. The only way to recover the box is to do a hard reset, as I cannot log in, nor su - to do a shutdown. In one case I happened to have a root shell open, and I still could not do a shutdown. Any ideas as to what I should do with this? As long as I don't expung everything is fine, but when I do expunge (move something or a filter runs in squirrelmail, or Action/Expunge in Evolution) sometimes it works fine, sometimes I get this error and a weird zombie state. It was all rock solid before this new version. Suggestions welcome - I don't seem to be getting any logging when it goes bad, perhaps I can up the log level? I'm more then happy to build the current dovecot from source, and if I should post this to some Fedora list, point me at it :D

[Dovecot] How to setup dovecot under MACOSX?
by CHENG Gao 22 Apr '05

22 Apr '05

I have built Dovecot 1.0 test 67 under MACOSX. But I can not find any tutorial on how to setup it. Please allow me to explain my need. I want to setup a local imap server, and then import all my email from Mail.app and Gnus into it. Thus I can choose to read emails with any client. It's only a single user environment. Could anyone instruct me if there is any tutorial for Dovecot MACOSX setting? Thanks in advance.

[Dovecot] maildir creation
by Renzetti Federico 22 Apr '05

22 Apr '05

Hi all, this is my first post to the list and sorry for my english. I have a mail server based on qmail+dovecot+ldap with virtualdomains and maildir stored in /var/vmail/<DOMAIN>/<USERNAME>/Maildir. When I create a user on LDAP I don't create maildir too. So if I log-in with dovecot (143,110) I hope dovecot creates maildir for users but this is not I get: maildir are not created... dovecot.conf .... default_mail_env = maildir:/var/vmail/%d/%n/Maildir .... There is a way to create automatically maildir for users? Thanks all. -- Renzetti Federico System/Network Administrator RedHat Certified Engineer Fabaris S.r.l.

[Dovecot] 1.0 release

I'm dying to use the 1.0 capability to use more than one mysql user pasword database. However, I'm too chicken to use 1.0-test in a production environment. Does anyone know if there is a planned release date for 1.0? Or can anyone say how risky it is to use 1.0-test?

[Dovecot] Disable multiple POP3 logins
by Jesus Salvo Jr. 21 Apr '05

21 Apr '05

Hi, With some POP3 servers, when you login more than once, the POP3 server says "Err: multiple login". How can I achieve that with dovecot ? For example: I login to my POP account that is hosted by the ISP: $ telnet pop.x.com 110 Trying x.x.x.x... Connected to pop.x.com (x.x.x.x). Escape character is '^]'. +OK <25628.1113981451@bne022mfe> USER mb13536d +OK PASS testcase +OK LIST +OK 1 4608 . STAT +OK 1 4608 While that pop3 login is still active, I run another telnet session to login again to the same account. $ telnet pop.x.com 110 Trying x.x.x.x... Connected to pop.x.com (x.x.x.x). Escape character is '^]'. +OK <11709.1113981546@bne021mfe> USER mb13536d +OK PASS testcase -ERR multiple login Connection closed by foreign host. Thanks, John

[Dovecot] message status changed from new to old on read
by Andrew Pimlott 21 Apr '05

21 Apr '05

Hi. I'm new to IMAP, but just tried uw-imapd and then dovecot in conjuction with offlineimap. I'm using Debian package version 0.99.14-1 and have my mail in mbox format. One of the first things that annoys me about both programs is that as soon as you read a mailbox over imap, the imapd changes all "new" messages to "old". It seems to have the assumption that the IMAP client is "reading" the messages, but particularly in the case of offlineimap, this assumption is not justified: I might not read the message on the client on which I've just synced, I might read it on the server or another client. So I would like dovecot to leave the mailbox alone, and leave it up to the client to write any changes to message status. Is there any option to dovecot that would accomplish this? While experimenting, I noticed that dovecot sometimes doesn't notice changes to the status made directly on the server. For example, if I create new mbox mailbox with one message (initially "new"), and access it with imap (using mutt in this example), it shows up "new" in the client. When I next access it with imap, it shows up "old", because dovecot modified the status as described above. If I then run mutt directly on the mailbox and change the status back to "new", then access it with imap, it still shows up "old". If I then remove the .imap directory containing the caches, it is back to "new". I assume that dovecot is supposed to pick up changes made directly on the server, right? Thanks for your help, Andrew

[Dovecot] minimial maildir++ quota for dovecot-0.99
by David Harris 21 Apr '05

21 Apr '05

Hello, I'm using dovecot-0.99.14, and I wonder if anyone has created patch for *minimal* Maildir++ support. By minimal Maildir++ support, I mean the following: (1) New messages created by dovecot will include the ,S=nnnnn string in the unique identifier so that Maildir++ clients don't have to stat the file to know the size. (2) Dovecot will append to the maildirsize file when a message is deleted or added. If maildirsize gets larger than the 5120 limit, then just delete it and let someone else recalculate the quota. My goal isn't full Maildir++ support in dovecot, but just to make it play nicely with my Maildir++ aware delivery agent. (If someone has full Maildir++ support, I'd be glad for that too!) If what I describe above doesn't exist, I am interested in paying someone to make this quick patch. E-mail me off list if you are interested. Thanks, David

[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 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/

[Dovecot] attr_names in test67

[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] 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 ?

[Dovecot] Failed to create storage with data:
by Matthieu Imbert 17 Apr '05

17 Apr '05

Hi, i'm using dovecot-1.0-stable. All my mail accounts are virtual accounts that come from pam with the following configuration in auth_default: passdb = pam userdb = static uid=5000 gid=5000 home=/var/mail/vhost/example.com/%n mail=/var/mail/vhost/example.com/%n for a user foo, if the directory /var/mail/vhost/example.com/foo already exists, then all is ok, but if the directory doesn't exists, it seems dovecot is unable to create it "on the fly". I get the following error message: Failed to create storage with data: /var/mail/vhost/example.com/foo i'm quite sure it is not a permission related problem (i made /var/mail/vhost/example.com world writable to be sure). I'm currently trying to understand the maildir code... But could someone tell me if the maildir directory should exist for dovecot to work ? In the case that the answer is yes, i would say in advance that it's a problem for sites hosting a lot of virtual users, since it means that these users must receive at least one mail for their mail account to work correctly (i use postfix as MTA, and if the user's maildir doesn't exist, postfix takes care of creating it). I'm not very fond of solutions with scripts taking care of creating users. Thanks in advance for your answers :) -- \|||/ (o o) Matthieu Imbert ooO-(_)-Ooo------------------------------------------ équipe administration réseau et systèmes Ecole normale superieure lettres et sciences humaines 15, Parvis René Descartes BP 7000 69342 LYON cedex 07 tél 0437376127, secrétariat 0437376122 fax 0437376123 contact équipe réseau et systèmes <reseau(a)ens-lsh.fr> contact personnel <matthieu.imbert(a)ens-lsh.fr> -----------------------------------------------------

The relavent section follows: ========================== [>>] Reading from client A00015 SELECT INBOX [<<] Reading from server * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 7668 EXISTS * 0 RECENT * OK [UNSEEN 7660] First unseen. * OK [UIDVALIDITY 1101063317] UIDs valid * OK [UIDNEXT 334080] Predicted next UID A00015 OK [READ-WRITE] Select completed.

The headers it gives for message #2 are the same as the first message in my mailspool, and the headers for message #3 are those of the second message in my mailspool. It goes on from there. This doesn't happen to other folders I try to access via IMAP, only my INBOX. Since this only seems to affect Evolution and not pine, I don't know whether this is technically a bug in dovecot or Evolution. I guess that's up to the RFC, which I haven't read all the way through. Anybody got an idea about how to fix this or what's causing it? (Please CC me directly on any replies, I'm not subscribed to this mailing list) Thanks, --Dennis Lambe, <malsyned(a)gmail.com> P.S. Is there a way to get a session transcript out of dovecot? It would save me a fair bit of perl hackery.

[Dovecot] Upcoming configuration file changes
by Timo Sirainen 17 Apr '05

17 Apr '05

For those who might be interested. Comments welcome. A few weeks ago I had started redesigning how Dovecot handles configuration files. I wrote a new parser and converted dovecot-auth to use the new way. Today I finally managed to convert imap process as well, which wasn't that easy because I didn't want mbox/maildir-specific settings to be hardcoded in any common code. So, the changes will be: - Dovecot master process will need a new completely different configuration file which tells what processes to run and their uids/chroots/memory limits. Very much like Postfix's master.cf. I'm not sure about its format yet (suggestions welcome), but maybe something like it's already: process imap-login { executable = /usr/lib/dovecot/imap-login chroot = /var/run/dovecot/login uid = dovecot vsz_limit = 32M } ... Hopefully after these changes the master process will become very small and simple. - One of the processes will be a configuration process, which is the one that reads and parses the configuration for non-master processes. The default configuration file format will be pretty similar to what we have now, but it can of course be replaced with SQL backends and whatever. Config process will listen in some unix socket waiting for requests from other processes, which connect to it just after they start up and maybe also sometimes later (eg. to get user/IP-specific settings when a new client connects). - The data that config process sends and what other processes parse is based on simple key=value pairs, so it's possible to still store and parse them from environment if needed. Also it makes it possible to override settings from command line (eg. imap -o mail_debug=yes) or give user-specific settings in userdb. Here's an example: # config process reads something like: mmap_disable = yes namespace foo { type = private separator = / mbox { dir = ~/mail mbox_read_locks = dotlock } } # sends out: mmap_disable = yes namespaces = foo namespaces_foo_type = private namespaces_foo_separator = / namespaces_foo_mbox = 1 namespaces_foo_mbox_1_dir = ~/mail namespaces_foo_mbox_1_mbox_read_locks = dotlock - Config process should verify that all given settings are valid so that typos are noticed. This may not be that easy because the setting definitions are distributed all around the source code. I think there needs to be at least a (Perl) script that finds out all the setting definitions and writes them to some all-settings.c for config process so it knows them. Settings for plugins are more difficult though.. Should they somehow be marked in config file that they're plugins (plugin foo { .. })? Or maybe config process could dynamically load all the plugins itself and request their setting definitions?
