[Dovecot] Pine and prefix - LIST command bug?
by Chris Wakelin 31 Mar '05

31 Mar '05

I've been having problems with Pine 4.62 talking to Dovecot 1.0 stable. It's fine when the folder collection path is empty, but if I have "~/mail/" or "mail/" it gives access errors (I'm using the "~/mail/", "mail/" etc. hidden namespaces for backwards compatability). It seems to me that Dovecot is not replying correctly to a "LIST" command with empty mailbox name: - Dovecot: xyz LIST "" "" * LIST (\NoSelect) "/" "" xyz LIST "~/mail/" "" * LIST (\NoSelect) "/" "" xyz LIST "mail/" "" * LIST (\NoSelect) "/" "" UW-IMAP; xyz LIST "" "" * LIST (\NoSelect) "/" "" xyz LIST "~/mail/" "" * LIST (\NoSelect) "/" ~/ xyz LIST "mail/" "" * LIST (\NoSelect) "/" mail/ RFC 2060 says: An empty ("" string) mailbox name argument is a special request to return the hierarchy delimiter and the root name of the name given in the reference. The value returned as the root MAY be null if the reference is non-rooted or is null. In all cases, the hierarchy delimiter is returned. This permits a client to get the hierarchy delimiter even when no mailboxes by that name currently exist. Mind you, it looks like at least our UW-IMAP also gets it wrong for "~/mail/". Of course, I may be misunderstanding something!

Mysql's string matches are case-insensisitive by default, so when dovecot asks mysql for the user information of UsEr1, it will get the information of user1 and therefore assumes that UsEr1 is a valid login. It's not dovecot's fault. If you want the match case-insensitive (so UsEr1 will be rejected), add the BINARY attribute to the userid field or change your query to '... WHERE BINARY userid = "%u"' in password_query and user_query. If you want to allow logins as UsEr1 (and let him access user1's mail), you have to change your dovecot.conf, I think. Use %h instead of %u there, and let user_query return the home directory with something like 'SELECT CONCAT('/var/spool/vmail/',LOWER(userid)) AS home, ...'.

[Dovecot] [ #14832]: Capital letters in POP3 logins
by support＠majordomo.ru 30 Mar '05

30 Mar '05

Hello all! I'm newbie here :) Using dovecot (version 1.0-test59, with mysql-auth) I saw strange problem: after authentication by POP3 in case that username given has capital letters, for example SupportTeam(a)majordomo.ru, dovecot creates new maildir 'SupportTeam' for this username instead reading mails from existing maildir 'supportteam'. Then dovecot scans created maildir 'SupportTeam' and returns 0 messages (sure:). IMAP4 works fine in the same time. Can I solve this problem or it is virtually "bug" of dovecot? Thanks in advance! Vladimir

[Dovecot] Chrooting dovecot.
by BSD Mail 30 Mar '05

30 Mar '05

Greetings, I have installed Dovecot under FreeBSD 5_3 It is pretty impressive. I got SSL working with no problem for both imap and pop3. Besides that I do still want to chroot Dovecot. I noticed that there are some options in the dovecot.conf that are intended for this. Unfortunately online resources on how to do that can't be found on google. Although I'm running the server as user dovecot. I still do have this: dovecot pop3-login 491 1 tcp4 10.0.1.4:995 *:* dovecot pop3-login 490 1 tcp4 10.0.1.4:995 *:* dovecot pop3-login 489 1 tcp4 10.0.1.4:995 *:* dovecot imap-login 488 1 tcp4 10.0.1.4:993 *:* dovecot imap-login 487 1 tcp4 10.0.1.4:993 *:* dovecot imap-login 486 1 tcp4 10.0.1.4:993 *:* root dovecot 481 5 tcp4 10.0.1.4:993 *:* root dovecot 481 6 tcp4 10.0.1.4:995 *:* Fine for the first six lines it's doing what it's doing. But the last two lines are running as root. That is why I want to chroot the server. I would like if anyone can point me to some howto or notes on how to do so. If there is none I will have to configure a jail just for this purpose. Thanks in advance. -- Regards,

[Dovecot] Abort error in current CVS version

I just tried the latest version from CVS and got this error: dovecot: Mar 29 18:11:33 Error: 27526 IMAP(todd.bluegenesis.com): Corrupted index cache file /mailhome/new/t/b/todd.bluegenesis.com/.imap/INBOX/dovecot.index.cache: Duplicated field in header: hdr.RESENT-TO dovecot: Mar 29 18:11:33 Error: 27526 IMAP(todd.bluegenesis.com): file index-mail-headers.c: line 68 (index_mail_parse_header_finish): assertion failed: (match[match_idx] != mail->header_match_value + 1) dovecot: Mar 29 18:11:34 Error: child 27526 (imap) killed with signal 6 I deleted the index files, didn't help.

[Dovecot] Compile Error in current CVS

Had a small error with the current CVS version. It was in deliver.c. Here's a fix. I'm assuming that adding NULL is correct ;-) dovecot.2005-03-29/src # diff deliver/deliver.c.orig deliver/deliver.c 86c86 < box = mailbox_open(storage, mailbox, MAILBOX_OPEN_FAST | --- > box = mailbox_open(storage, mailbox, NULL, MAILBOX_OPEN_FAST | Here's the symptoms: deliver.c: In function `save_mail': deliver.c:87: warning: passing arg 3 of `mailbox_open' makes pointer from integer without a cast deliver.c:87: error: too few arguments to function `mailbox_open' make[3]: *** [deliver.o] Error 1 make[3]: Leaving directory `/services/src/9.2/dovecot/dovecot.2005-03-29/src/deliver' make[2]: *** [all-recursive] Error 1 make[2]: Leaving directory `/services/src/9.2/dovecot/dovecot.2005-03-29/src' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/services/src/9.2/dovecot/dovecot.2005-03-29' make: *** [all] Error 2

[Dovecot] Checkin 1.37 of src/lib-storage/mail-storage.c
by Geo Carncross 29 Mar '05

29 Mar '05

Checkin 1.37 of src/lib-storage/mail-storage.c added a parameter to mailbox_open() but this broke building src/deliver/deliver.c as revision 1.2 doesn't use the new parameter. It looks like save_mail() of src/deliver/deliver.c calls mailbox_open() and it looks like it might work fine if it were to use a (struct istream *)0 as the third parameter (instead of the flags) -- but I don't use deliver [yet], so I don't have any adequate way to test this. -- Internet Connection High Quality Web Hosting http://www.internetconnection.net/

[Dovecot] mbox zlib compression plugin
by Timo Sirainen 29 Mar '05

29 Mar '05

Some people have been asking this forever, but because it wasn't possible to implement it as a plugin, I hadn't done it. Now, due to some API changes for other purposes, it was suddenly easy. So, if you want to try it, grab the latest CVS code / nightly CVS snapshot and http://dovecot.org/patches/1.0/zlib-plugin.tar.gz Compilation instructions inside zlib-plugin.c file. What it does is check if mbox name ends with ".gz", if so it opens it as read-only using zlib. If the file isn't actually zlib compressed, zlib seems to be able to still access it as a normal file (but it's still read-only). It should be possible to implement it for maildir files as well by hooking into mail_get_stream().

[Dovecot] FC2 POP Configurtion
by Linux Stuff 29 Mar '05

29 Mar '05

I'm a newbie to dovecot and a little bit less of a newbit to linux. I am in the process of moving my server from RH9 to FC2. The only obstacle remaining is my email. I run sendmail with netscape mail clients - mostly PC's. They all can read their mail but none of the users can send. Depending on the state of the dovecot.conf file, I get the following: Mar 28 16:04:14 corvette sendmail[5810]: unable to open Berkeley db /etc/sasldb2: Invalid argument Mar 28 16:04:14 corvette sendmail[5810]: unable to open Berkeley db /etc/sasldb2: Invalid argument Mar 28 16:04:14 corvette sendmail[5810]: no secret in database I know I must be missing something, probably trivial. Does someone have a simple, easy-to-read, config file for dovecot pop running with sendmail? Thanks
