[Dovecot] Dovecot 1.0-test45 indexing issues
by dovecot＠spam.turbolink.net 28 Sep '04

28 Sep '04

We're currently on dovecot 0.99.10 with a few modifications (including one very nasty hack for the blank line at the beginning of the mailbox bug). We're using mbox all around. Everything works smoothly but we still ocasionally get corrupt mailboxes and indexes that need to be wiped out. I setup 1.0-test45 on one of our mailservers to start testing it and ran into a few issues. The first one is if I try to use mail_read_mmaped=yes I get this error: Error: POP3(sobo1): file istream-raw-mbox.c: line 410 (istream_raw_mbox_get_body_size): assertion failed: (rstream->mail_size != (uoff_t)-1) for every mailbox. If I switch to mail_read_mmaped=no everything works, but performance is extremely bad. I have a few test mailboxes with about 20k messages and if I toggle a message flag from unread to read, dovecot seems to re-read the entire mailbox up to that message (I saw this with strace). Is this how supposed to work?? I don't see behavior like this on 0.99.10, and on a mailbox with any substantial number of messages it really slows things down. Thanks for any input. - Mike

Restarting Dovecot doesn't kill the existing processes which are still using the old directories and since they're gone they begin complaining. Correct way to do moving would be: kill dovecot killall imap move directories start dovecot

[Dovecot] Moving mail dirs
by Mark Lidstone 28 Sep '04

28 Sep '04

Hi all, This is probably a silly question, but I have a problem. I've had to move my users maildirs from: maildir:/home/%u/.Maildir To maildir:/data/mail/%u I've updated the MTA to put mail to the correct place and it's working fine. I've also changed the dovecot.conf file and restarted dovecot and I thought that would be all I needed to do. However, the users are getting lots of error messages, and looking in the relevant logs shows lots of entries like: Sep 28 14:03:36 <hostname> imap(<user1>): stat() failed with file /home/<user1>/.Maildir/new: No such file or directory Sep 28 14:03:36 <hostname> imap(<user2>): utime() failed with index file /home/<user2>/.Maildir/.INBOX/.imap.index: No such file or directory (Sorry for changing usernames and hostname, but I'm neurotic about that kind of thing) What have I missed? Or am I not supposed to move maildirs once they're in use?

Hi all, I have a temporary fix in case anyone is reading the archives with the same problem. Link the old location to the new location. E.g: mv /home/user/.Maildir /data/mail/user ln -s /data/mail/user /home/user/.Maildir Still no idea why dovecot is still looking in the original folders though.

[Dovecot] Thunderbird 0.8 - Inbox grayed out and does not update
by Sitapati das 27 Sep '04

27 Sep '04

Hi all, I cannot get Thunderbird 0.8 to work with my dovecot IMAP server. It works fine with my work IMAP account - I'm not sure what they are using. What happens is that folders that I create in Thunderbird or Evolution can only contain subfolders or messages, not a combination of both. Folders which contain subfolders and not messages show up in Thunderbird grayed out. I can expand them and view the subfolders and the messages within those. The Inbox however, also shows up grayed out. When I look inside I can see the messages that were there when I created the IMAP account in Thunderbird, however, no new messages arrive, even after restarting Thunderbird. If I connect with Evolution 1.4 I can read the inbox without a problem. Has anyone seen this? warm regards, Joshua

[Dovecot] Concerned about Dovecot's new NTLM code
by Andrew Bartlett 26 Sep '04

26 Sep '04

I'm pleased to see another project increasing compatibility with windows clients, by the addition of NTLM login support, but I'm a bit worried about a few implementation details, and hope to offer an alternate approach. I mean no disrespect to those who have implemented to the code so far, but I feel that the idea of 'everybody re-implement NTLM' is prone to failure. Firstly, to bugs I've noticed by casual inspection of your implementation: - Unicode support is by 'null padding' - there is no real support for non-ascii characters. - NTLM2 (a negotiated scheme to avoid sending the LM response) is unsupported - NTLMSSP is NDR, not 'C struct pushed to the wire', it needs to be correctly marshaled and unmarshaled. There are other missing features, some of which are rumoured to become mandatory flags in future, but more importantly, because the implementation is standalone, it has no ability to integrate into an NT/Win2k/Samba domain. As part of the Samba team, I have worked with other projects - Squid in particular, to deliver server-side (and client-side) NTLMSSP authentication, without the need to re-implement the NTLMSSP protocol. This is done by a callout to 'ntlm_auth', a Samba 3.0 utility designed for this purpose, which in turn can contact domain controllers, allowing for seamless single sign on. http://samba.org/samba/docs/man/ntlm_auth.1.html I have recently completed reworking mod_ntlm_winbind for a similar purpose, and have patches for cyrus-sasl in my 'lorikeet' subversion repository. These should serve as good examples for the simple fork()/exec() modal that is used, and also show the support for GSS-SPNEGO (aka HTTP Negotiate) that ntlm_auth also provides. http://download.samba.org/ftp/unpacked/lorikeet/trunk/ My hope is that I can tempt a Dovecot developer to take on the challenge of modifying the dovecot to use ntlm_auth, and am most willing to answer any questions (here, by private mail or on the samba-technical list) that you may have on the issue.

[Dovecot] problems with cvs version and vpopmail
by Kristoffer Ek 24 Sep '04

24 Sep '04

Hi, I have tried compiling the latest cvs version of dovecot on my FreeBSD 5.2.1-release box with the ports version of vpopmail: 5.4.3_1. In the configuration file I have two auth paragraphs, one for passwd authentication and one for vpopmail-auth: auth vpopmail { mechanisms = plain userdb = vpopmail passdb = vpopmail user = vpopmail } But the vpopmail dosn'nt work. I got the folowing in the log: Info: auth(vpopmail): vpopmail(stoffer(a)test.ek.dk): unknown user (stoffer(a)test.ek.dk) When I ktrace the dovecot process, it seams that it is trying to access the mysql db, but it ignores the settings in ~vpopmail/etc/vpopmail.mysql If I use the ports version of dovecot it works, but of course without the multiple auth capability since it is version 0.99... Any hints on debugging? - kristoffer -- 1st graffitiist: QUESTION AUTHORITY! 2nd graffitiist: Why? Kristoffer Ek http://ek.dk/ +45 20 40 00 05
