Hello, I am having problems with configuring dovecit. The imap directory was correctly made in ~/mail/.imap But I can't see any mail headers. My mbox path is ~/mail/incoming Currently I am trying to use "mbox:~/mail/:INBOX=~/mail/incoming" for configuration but it complains about missing value. Can someone send me more information on configuration directives especially mbox and INBOX. Early reply shall be appreciated. Regards, Mahesh

[Dovecot] better body and text search?
by Mark Anderson 28 Aug '03

28 Aug '03

I was wondering what plans dovecot has for text and body search? This is one of those issues that *no* imap implementation ever seems to document :(. Not cyrus, courier, bincimap, or dovecot.... i speed-read some of the sources and found src/lib-mail/message-body-search.c After a quick scan, it seems: - it uses no text index at all, but does a linear search over the folder. - it searches only messages with content-type starting with "text/" or "message/" - it does no special parsing of "text/html", so tags and attributes would match - it appears to exclude any mime messages, since it skips "multipart/mixed" for example. - it does deal with content encoding and charset. There is a lucene-based text indexing utility for IMAP stores here: http://www.tropo.com/techno/java/lucene/imap.html But ideally there would be pluggable text indexing builtin.... -mda

[Dovecot] mail accounts for users without home dirs
by Gunter Ohrner 28 Aug '03

28 Aug '03

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi! I use dovecot on a machine where users without an existing home directory (Not my idea...) need to access their mailboxes. Unfortunately dovecot tries to chdir to the users home directory before allowing IMAP access - is there anything I can do about that besides creating a dummy-homedirectory for these users?

[Dovecot] 0.99.11-test6
by Timo Sirainen 28 Aug '03

28 Aug '03

http://dovecot.procontrol.fi/test/ I think I've fixed the problems that were corrupting indexes with the new code. It happened every time you had expunged some messages and new messages arrived. I think this release might actually work :) disable_plaintext_auth = yes will be default from now on. It allows plaintext authentication from localhost (127.*, ::1) however. I just figured out that the lockless cache file reading prevents me from fixing the mbox code to work the same way it used to. I'm not sure actually how this would be best fixed.. Problem is that headers in mails change and move the messages around in the mailbox, so I have to keep track of them. Previously I just updated the header size in index files.. but without read locks this can't be done safely. One possibility would be to parse the whole mbox file every time when the mailbox is opened (or when it needs to be read) and save the header sizes in memory. That'd make it slower than it is today though.. Or maybe it'd work if I just grabbed exclusive lock whenever reading header sizes. They could be then copied into memory to avoid locking more than once. But that still creates locking contention if lots of clients are reading the mailbox. Exactly in the situation where I'd mostly use mboxes.. I could also save it in .imap.index file which still currently uses read-locks. But I'd rather want to get rid of them in there too.

[Dovecot] IMAP error after login
by Nicolas STRANSKY 28 Aug '03

28 Aug '03

Hello, I'm having a slight problem with Dovecot (0.99.10-0.rc2, on Debian woody). When using mozilla 1.4, there is an error message from the mailer just after login, but nothing in dovecot logs. "Alert The current command did not succeed. The mail server responded: Error in IMAP command UID: Too long argument.." How could I fix this problem ? Thanks, -- Nico J'ai une panne de micro et les parasites me brouillent l'écoute

[Dovecot] Chrooting the Mail processes
by Bert Koelewijn 25 Aug '03

25 Aug '03

Hello! Could somebody give some feedback on this configuration: - OpenBSD box with local ssh users. - /home directory mounted with nosuid,noexec. - postfix dropping mail in /home/username/mail/INBOX, with the UID/GID of the user. - dovecot: valid_chroot_dirs = /home default_mail_env = mbox:/home/%u/mail/:INBOX=/home/%u/mail/INBOX Are there any obvious ways for a local user to help dovecot escape the chroot jail? How can I check that dovecot is REALLY using /home as chroot jail for the imap process? Thanks! Bert Koelewijn

[Dovecot] Docs on the wiki
by Bob Hall 25 Aug '03

25 Aug '03

I went to the Dove Wiki page and added a couple of docs. There's a DoveWikiMainPage link at the top of the first page now. Click on that and the next page has links to the two docs. Someone who knows more than I do about wiki formatting should make this look good. The two docs are for Dovecot/OpenLDAP installation. The first is detailed instructions and the second is a cheat sheet. You don't need to contact me if you find errors; just click "Edit this page" at the bottom. Anyone who wants to use parts of my docs to use in documenting other types of installation should feel free. There's no mention of copyright policy, but I assume everthing is GPL copyleft. Bob Hall

[Dovecot] Postfix and Maildirs
by Steve Sloan 24 Aug '03

24 Aug '03

Hope someone can help me with this as I am presently stuck I am setting up a new server with Dovecot 0.99.10, Redhat 9.0, Postfix, Amavisd-new and maildir's in the users home drive. I am using Netscape mail 7.1 as the main client to access the mail store via imap which works fine and various other imap clients can access the maildirs Ok as well. The problem is when Postfix delivers a message is insists on making a second Maildir directory in the user's home drive and put the message in there. The Maildir's are being created automatically ie. I didn't use maildirmake. Even if I delete one of the Maildir's it just gets recreated again. ie. this is the test user's home drive drwx------ 10 test2 test2 4096 Aug 23 20:53 Maildir drwx------ 6 test2 test2 4096 Aug 24 11:05 Maildir This is the Maildir that the clients are using and being accessed by Dovecot drwx------ 10 test2 test2 4096 Aug 23 20:53 . drwx------ 4 test2 test2 4096 Aug 24 11:05 .. drwx------ 2 test2 test2 4096 Aug 23 19:58 cur -rw------- 1 test2 test2 5 Aug 23 19:58 .customflags drwx------ 5 test2 test2 4096 Aug 23 19:59 .Drafts drwx------ 2 test2 test2 4096 Aug 23 19:58 .INBOX drwx------ 2 test2 test2 4096 Aug 23 19:58 new drwx------ 5 test2 test2 4096 Aug 23 20:15 .Sent -rw------- 1 test2 test2 29 Aug 23 20:13 .subscriptions drwx------ 5 test2 test2 4096 Aug 23 20:11 .test drwx------ 2 test2 test2 4096 Aug 23 19:58 tmp drwx------ 5 test2 test2 4096 Aug 23 20:11 .Trash and the other one which Postfix user's drwx------ 6 test2 test2 4096 Aug 24 11:05 . drwx------ 4 test2 test2 4096 Aug 24 11:05 .. drwx------ 2 test2 test2 4096 Aug 24 11:05 cur -rw------- 1 test2 test2 5 Aug 24 11:05 .customflags drwx------ 2 test2 test2 4096 Aug 24 11:05 .INBOX drwx------ 2 test2 test2 4096 Aug 24 11:05 new drwx------ 2 test2 test2 4096 Aug 24 11:05 tmp This one has no index files and looks just like a courier Maildir For Postfix main.cf I have set home_mailbox = Maildir/ and /etc/dovecot.conf default_mail_env = maildir:/home/%u/Maildir Hope this make sense to someone Steve -- _____________________________________________ LanSol Computers 283 Sir Donald Bradman Drv.

[Dovecot] Three oddities
by Bob Hall 24 Aug '03

24 Aug '03

FBSD 4.8, Dovecot-0.99.10 1) I have mail accounts for people who use Macs and Windows, so their mail is stored on a Unix box where they don't have accounts. When their mail comes in, it is stored in /var/mail/<accountname>. When I was setting this up, I used my own Unix account for testing, and that works fine. But for the other mail accounts, which don't correspond to Unix accounts, I want to give ownership of the /var/mail/* files to another account that doesn't have my privileges. However, no one can access their mail unless I own their files. As long as I own all the /var/mail/* files, everything works fine. But if I shift ownership to another account, users can log on to Dovecot but attempts to access an IMAP folder return an error. >From maillog: Aug 18 16:39:46 kongemord imap(philrodrigues): mkdir_parents(/var/mail/philrodri gues/.imap/INBOX) failed: Permission denied All files and directories in /var/mail/* are in the mail group. I tried adding dovecot to that group, but that didn't help. Since everyone can log on to Dovecot, but can't access their mail unless I own their files, I'm assuming that there's some simple ownership setting that I'm overlooking. But I haven't a clue what it is. Can someone tell me what I need to change? 2) The Macs have Eudora 4.2 installed, and the Win boxes have Eudora 5.1. The Macs can delete mail, put it in the trash, and empty the trash. The Win clients can mark mail deleted, but they can't remove it. The mail stays in the IMAP folder until the same user accesses their mail from a Mac and deletes it. If a user drags a message to another folder, a copy is created in the new folder but the old copy remains in the original folder. I'm not having this problem with Mutt, so it the problem seems to be specific to the Windows verson of Eudora. Is there a fix? 3) We're pulling our e-mail off our ISP's POP server and loading it into Dovecot to allow people to work with their mail from different machines. I'm using getmail to make the transfer. Is anyone else doing POP to IMAP, and how are they doing it? Any suggestions? TIA, Bob Hall
