[Dovecot] Outlook strange behaviour...
by Francois Meehan 13 May '05

13 May '05

Hi all, I have a Dovecot server(dovecot-0.99.14) running with IMAP support, running on a Fedora 2 system. Outlook (2003) users receive duplicate mail, "the" second mail doesn't have a title, when clicking on it, we are getting "non fully downloaded" error message. When deleting the "orignal" mail, all duplicates gets deleted too. Any ideas? Thanks in advance, Francois Random Thought: --------------- Colors fade, temples crumble, empires fall, but wise words endure. - Edward Thorndike

[Dovecot] problem with test69
by Cor Bosman 13 May '05

13 May '05

Hi all, I noticed a problem with test69. I can recreate it with the following steps: - create a folder - copy about 200 emails from INBOX to this folder The copy succeeds, I can see with rawlog that it actually moves the 200 emails around. I can see on the spool that there are 200 emails. This is maildir, with spool over NFS. Now I immediately select the new folder. I now see only a part of the emails reported. And with rawlog I indeed see something like: * FLAGS (\Answered \Flagged \Deleted \Seen \Draft Junk) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft Junk \*)] Flags p ermitted. * 158 EXISTS * 158 RECENT * OK [UNSEEN 3] First unseen. * OK [UIDVALIDITY 1115970206] UIDs valid * OK [UIDNEXT 217] Predicted next UID 2 OK [READ-WRITE] Select completed. My client faithfully reports 158 instead of 200. If I now close/open my client, and re-select, I see 200. This I can reproduce with several different clients, but its pretty obvious it isnt a client issue. I also reproduced this with different users. Anyone see this also? NFS issue? Cor

[Dovecot] dovecot 1.0-test69 io hangs
by Jens Laas 13 May '05

13 May '05

I've been testing test69 with pop3 (under Linux and with mbox). I began testing with a large inbox (11000 mails) and it seems the communication between dovecot and the mailclient (evolution) stalls after 1000-2000 messages transferred. I've looked in to the (non-trivial) io functionality of dovecot. What I see is that io_loop_handler_run() in ioloop-poll.c does not signal any more data (and eventually the whole thing timeouts). Evolution downloads the mailbox fine via qpopper. I tried turning on rawlog: mail_executable = /usr/libexec/dovecot/rawlog /usr/libexec/dovecot/pop3 I cannot find any logfile.. I must be missing something. Any help or ideas ?

[Dovecot] "shared mailboxes"
by schnitzel meister 12 May '05

12 May '05

Hello, After a long search I've almost settled on dovecot as a pop3 and imap server. I have just one problem.. Rather than have a list support(a)company.com, I'd like to have a shared mailbox. The dovecot homepage explicitly states "Shared mailboxes aren't _yet_ supported." The sentence implies that they're planned - any idea when? Thanks

[Dovecot] IDLE command timeout
by Sim Harbert 12 May '05

12 May '05

Is it possible to change the IDLE command timeout to be more than 30 minutes? I have a client on my PalmOne Treo 600 which will stay in IDLE mode as long as it can. I would like to set the timeout to something much higher than 30 minutes. Maybe several hours or even more. I don't see a configuration setting for this value in "/etc/dovecot.conf". Am I missing something? Thanks, -Sim

[Dovecot] 1.0-test69
by Timo Sirainen 11 May '05

11 May '05

http://dovecot.org/test/ - Several mbox fixes, upgrade recommended for test68 mbox users - Possibly fixes some IMAP hangs where Dovecot just stopped replying - Fixed delay-newmail workaround. It was badly broken before. And somewhat off topic advertisement: I got a bit distracted from Dovecot a week ago when a guy started mailing me about wanting to write an irssi2 client as a project to learn Ruby. Half a year ago I had written a semi-working irssi2 server but I got stuck with it because I wasn't interested about writing client for it. Now that the client actually works, irssi2's development has kind of exploded :) Irssi2 is a bit related to Dovecot too, in that it'll be integrated with it more or less tightly to provide instant messaging support. Nothing prevents extending irssi2-protocol to support all other kinds of realtime events either, for example to send new mail notifications. If you're interested, see: http://main.irssi.org/projects/irssi2.html And for the lazy, here's the introduction copy&pasted: Shortly put, irssi2 is to instant messaging what IMAP is to mail. You can safely exit your irssi2 client, and irssi2 server just keeps on going. When you connect back with your client, you can see all the discussion that happened while you were away (and even older discussion, too, if you want). You can also use multiple clients even at the same time, so you could for example keep one client always open at home and still be able to check what's going on with your mobile phone. Irssi2 clients are encouraged to keep their configuration in server side, so nothing should prevent you from temporarily using another irssi2 client from your friend's home with no other configuration needed than irssi2 server's address, your username and password. Irssi2 is designed to support multiple chat protocols (IRC, SILC, MSN, ICQ, etc.) but without ignoring hardcore IRC users. That means that unlike all other similar attempts (such as Jabber), irssi2's client-server protocol will actually allow fully featured irssi2 IRC client to be written with no compromises (but still the same client can be used to talk to MSN and elsewhere). Note that irssi2 isn't trying to replace IRC servers (yet ;). irssi2 server simply connects to normal IRC servers just as a regular IRC client. To prevent mixups with these terms, IRC servers are usually called "gateways" in irssi2.

[Dovecot] Dovecot Sendmail Maildir
by Gabriel Granger 11 May '05

11 May '05

Hi all, I'm using Debian (testing) for my office mail. I'm using sendmail and Dovecot to deliver email to clients over IMAP using mbox format. I want to move over and start using Maildir. I know that I can use different MTA's to do the job, but I really like sendmail, and I run additional sendmail servers across the my internal and external networks. I'm probably being anal, but I want to keep my MTA the same across the board. Does anyone here use sendmail + dovecot + maildir? if so what's the best way of going about this? Gabe

[Dovecot] Standard dirs
by Claudio Succa 10 May '05

10 May '05

Hi, thank to developers for such a flexible imap server. Is solves succesfully my needs to have a single passwd file for clients accessing both imap/imaps and pop3/pop3s protocols (on a diskless mail/web server with NFS maildirs and NFS indexes!). My question: With 1.0-test68 I have to set login_dir=/var/run/dovecot-login (just a dir not under /var/run/dovecot) instead of /var/run/dovecot/login. I guess that imap-login (running with uid=dovecot) can't access /var/run/dovecot/login if it is under /var/run/dovecot because it is set with permission 0700 and uid=root by dovecot. How can I run dovecot with its standard login_dir config?

[Dovecot] problems with ldap auth
by Nuno Lopes 10 May '05

10 May '05

I'm trying Dovecot v1.0-test43 with ldap authentication but can't seem to make it work. I'm getting the following errors in the log: dovecot: Sep 16 19:50:09 Info: Dovecot v1.0-test43 starting up dovecot: Sep 16 19:50:10 Error: Auth process died too early - shutting down What can I do to see where the error is? I have this configuration working with dovecot 0.99.xx . And if I replace the ldap authentication scheme with another one it starts up right. Following some past mailing list sugestions I've also tried removing most of the auth modules from the compilation but it made no diference. You can see my configuration files in: http://iluvatar.portugalmail.pt/dovecot/dovecot.conf http://iluvatar.portugalmail.pt/dovecot/dovecot-ldap.conf (I've intalled the binaries in /opt/dovecot) Don't know how much more data I can provide to help finding out what the problem is here (I think this won't be enough unless there's a known bug). Thanks, -- Nuno Lopes

[Dovecot] trouble getting digest-md5 & ldap working
by Udo Rader 09 May '05

09 May '05

hi, I am trying to set up dovecot with digest-md5 as authentication mechanism and openldap as passdb. My problem is ... that I just can't get it working. PLAIN authentication works as expected, but no luck with digest-md5. An excerpt from the two configuration files: dovecot.conf: --------CUT-------- auth = default auth_mechanisms = plain digest-md5 auth_userdb = ldap /etc/dovecot/dovecot-ldap.conf auth_passdb = ldap /etc/dovecot/dovecot-ldap.conf --------CUT-------- dovecot-ldap.conf: --------CUT-------- user_filter = (&(objectClass=posixAccount)(|(mail=%u)(uid=%n))) pass_filter = (&(objectClass=posixAccount)(|(mail=%u)(uid=%n))) default_pass_scheme = plain --------CUT-------- My dovecot installation with plain authentication and OpenLDAP has been quite mature for a long time, so I doubt that it is an issue with openldap. >From Cryrus-SASL I know that in order to get DIGEST-MD5 running it is required to have plaintext passwords in the DIT, but that does not solve anything. syslog tells me this: dovecot-auth: May 08 21:25:09 Error: ldap(frodo): No password in reply So any ideas on where I went wrong?

[Dovecot] transparent proxy
by Mark E. Mallett 09 May '05

09 May '05

I'm excited to see that dovecot 1.0-test series supports transparent proxy, but that excitement is muted by: - the recommendation to avoid 1.0 at present; - the requirement to use SQL authentication. I guess I could ignore the first, but the second is sticky. How hard would it be to hack a different sort of proxy server cue into the authentication? Perhaps one of: If authenticating via passwd, use a gid as an index into a server table (or perhaps have the group name be a server name), If passwd authentication fails, try a starting the proxy to a specific other server and see if one can log in there. Or something else.. I dunno, I'm just looking not to install a SQL server just for this. mm

[Dovecot] index file corruption

Hello everyone. I am new to the list, so forgive me if this has been discussed already. My configuration is as follows: Fedora Core 3, fully patched through yum through today. Dovecot 0.9.9.13 Postfix 2.1.5 Using Maildir with Mail stored in ~/Maildir My issue is that, for some odd reason the inbox file index gets corrupt, There is no rhyme or reason as to why it happens or when, but a simple rm -rf ~/Maildir/.INBOX fixes everything (I assume because Dovecot rebuilds the index file.) Has anyone else on the list seen this? Is there some workaround for it? Andy

[Dovecot] dovecot 0.99.14 and imaps (SSL) "hangs"
by Frode Nordahl 08 May '05

08 May '05

Hello, I just decided to try dovecot again after a long pause, and I must say that I am very impressed with the speed and resource usage, even when running with UNIX mailboxes. However, I have a problem with SSL. Every two minutes the connection is frozen, and the client has to reconnect after it times out waiting for a response from the server. My IMAP client fetches all headers, and then caches all messages in my mailboxes. However, if I do this while connected to dovecot using SSL (imaps, port 993) the connection times out roughly every two minutes, and the IMAP client must close the connection, reconnect and resume operations from where it left off. This makes resynching a 40000 message 300MB folder take VERY long :-) Using the same client, connected to the same server and syncing the same mailbox connecting to regular imap port (no TLS, port 143), everything works smoothly. The very same client, server and mailbox works flawlessly with uw-imapd and SSL. I have turned on rawlog, and everything seems to be OK. I am unable to dump the wire, because it's SSL, so not sure what to do to debug this. One thing I find a bit strange is that /var/run/dovecot/ssl-parameters.dat is a 0 byte file. Is this normal? Client: Apple Mail 1.3.11 (v622) Server: dovecot 0.99.14, installed from ports on FreeBSD 5 dovecot.conf: Regards, Frode Nordahl

[Dovecot] pop vs. imap inconsistancy
by jeff sacksteder 08 May '05

08 May '05

I am converting from courier and have noticed change in behaviour with Dovecot. I use maildirs with squirrelmail connecting by imap as well as a POP3 client. Courier would set the 'mail status-read' flag for any message which was downloaded with the POP3 interface. Dovecot apparently does not. Is this a bug or intended behaviour? If it is intentional, can it be changed with the config file?

[Dovecot] Outlook Duplicates issue is still killing me
by Jeff Ramsey 08 May '05

08 May '05

Hi, I have one pop3 client who has three computers, and he has Outlook XP on two, and 2003 on the third. They are all set to leave a copy of messages on the server, and that causes a duplicate message for every message he gets. I then can tell him to uncheck the "leave a copy on the server" box, and pop his mail, and the duplicates will go away for two or three days, only to start up again. I have a stock Fedora Core 2 server with dovecot and Sendmail. I do a nightly yum, so as to stay up2date. My version of dovecot is 1.0-test42. Has anyone else seen this issue? What can I do to fix it, short of permanently unchecking that box in Outlook? (The user is my boss, and he likes to get his email on all three computers...) -- Jeff Ramsey MIS Administrator Tubafor Mill, Inc.

[Dovecot] Test68 and Namespaces
by Jim Summers 08 May '05

08 May '05

Hello List, I am in the process of building a new mail system here. I am hoping to eventually migrate my users from mbox storage to maildir. They have been using mbox forever and would rather get used to maildir slowly. So I have come upon the idea of using namespaces to provide the different mailstores. Since this isn't available in the current stable, or at least I could not figure out how to do it, I have been working with 1.0-test68 since it provides the ability to configure things with the namespaces. But I am seeing an error pop up in my maillog file when exiting the client, it is: ============================================ May 3 08:11:41 tbox dovecot: IMAP(sub4000): file mbox-sync.c: line 1371 (mbox_sync_do): assertion failed: (sync_ctx->mbox->mbox_sync_dirty) May 3 08:11:41 tbox dovecot: child 12717 (imap) killed with signal 6 ============================================ Wasn't sure if it is a code bug or if it is how I have the namespace entries setup. In my dovecot.conf file I have: ------------------------------------ namespace private { separator = / inbox = yes # prefix = "#mbox/" location = mbox:~/Mail/:INBOX=/var/mail/%u } namespace private { separator = / prefix = md/ location = maildir:~/Maildir } namespace private { separator = / prefix = mail/ hidden = yes } namespace private { separator = / prefix = ~/mail/ hidden = yes } namespace private { separator = / prefix = ~%u/mail/ hidden = yes } ------------------------------------ All seems to work except the message showing up in the logs. My goal/setup is to provide: 1. mbox delivery in the mailspool(/var/mail) from sendmail 2. access to existing ~/Mail/ mbox storage. 3. ability to begin setting up / migrating to maildir in ~/Maildir Is my namespace config above overkill / borken / wrong? Ideas / suggestions on this would be greatly appreciated. Environment: Server to be: RedHat AS EL4 Clients: Thunderbird, Evolution, mutt, pine, mailreader on OS/X.

[Dovecot] test-68 coredump
by Gregory Bond 08 May '05

08 May '05

I've tried upgrading from test-51 to test-68, with mixed results. It seems to fix the problem I had with imap and Thunderbird getting confused and not showing headers or body for some email. But something in dovecot is coredumping when I select certain mailboxes. Thunderbird just hangs when you select that mailbox, and mutt gets an EOF on the imap socket while "fetching message headers". Other mailboxes seem to run OK. The failing ones _might_ be empty or have only 1 message in them. Removing index files doesn't help. There is a core file in /var/run/dovecot, and file(1) says it's from dovecot-auth, but GDB can't make sense of the core with that executable, and the login has well and truly run when the core happens. (The core doesn't seem to be from the imap process either.) Any clues how I might debug this? [Solaris 2.8, gcc-3.3, dovecot test-68, imap+Maildir, Thunderbird 1.0.2 on OSX and mutt on Solaris]
