[Dovecot] converting from courier-imap
by Emily 30 Aug '03

30 Aug '03

Hello. I apologize if there is a simple answer to this question, but I haven't been able to figure it out. Our people use various clients (pine 4.50 with maildir patch, eudora, messenger, outlook, squirrelmail), and all of them work with courier-imap. But I've become very interested in dovecot after reading about it, so I'm trying it out on another server. The results are mixed. Strangely enough, squirrelmail 1.4.1 works wonderfully. For some reason, it duplicates Sent, Drafts, and Trash, but I deleted the duplicates and it was fine. Mozilla messenger is also fine, but with the same duplication of those special folders. Everything seems nice and fast. But some of our users still cling to pine, which works with courier-imap using these three lines in .pinerc: inbox-path={our.server.edu/ssl/novalidate-cert/user=emily}INBOX default-fcc={our.server.edu/ssl/novalidate-cert/user=emily}INBOX.Sent folder-collections="IMAP Folders" {our.server.edu/user=emily/ssl/novalidate-cert}INBOX.[] On the test server I'm using dovecot-0.99.10 compiled against openssl-0.9.7b in Redhat 9. This pine configuration worked in courier, but when I try pine with dovecot, I can't see any folders under "Folder Collection" other than those special three (Drafts, Sent, Trash). I'm sure there's just something I'm doing wrong, but I couldn't find anything in the dovecot list archives. I would appreciate any advice on what I'm doing wrong in getting pine to see the whole collection. Thanks, -- Emily

[Dovecot] No localhost after reboot
by Bob Hall 30 Aug '03

Rebooted the server box today. Now Dovecot doesn't listen at localhost. It does listen at the LAN interface, so it is perfectly usable, but... Does anyone have any idea why it has stopped listening at localhost? Bob Hall

[Dovecot] Postgresql and Dovecot
by Michael Ducy 29 Aug '03

29 Aug '03

I am having some issues getting dovecot to work with postgres. Dovecot starts up and runs fine without using postgres (ie passwd and pam). There is nothing in /var/log/messages other than: Aug 28 12:44:05 mail dovecot: dovecot startup succeeded Then ps -A shows no running dovecot processes (or the imap-login or pop-login). I have tried with both the RPMs that are on the download page and buidling it myself on 2 different boxes (yes I configured with --with-pgsql - Red Hat 7.3 and Red Hat 9.0). Any suggestions would be appreciated as this is the only imap/pop server with pgsql support and flatfile support I can find. Michael

[Dovecot] better body and text search?
by Mark Anderson 29 Aug '03

29 Aug '03

(this is a resend, sorry if duplicate but my first post didn't get through). 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] Custom flags.
by Maheshkumar Sabhnani 29 Aug '03

29 Aug '03

How do I define custom flags? What are added features of IMAP apart from Online access and Hierarchy folders. I created a new folder and copied couple of messages from incoming file. Where is this new folder created? Also Microsoft Outlook still shows the messages in incoming as deleted. How do I refresh list to permanently delete the messages that I have already transferred to a different folder. Mahesh

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] 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

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.
