[Dovecot] Just delete that index
by Doug Luce 20 Dec '04

20 Dec '04

I get a few messages of this ilk each day: Dec 16 01:56:31 aurora dovecot: IMAP(doug): Corrupted index cache file /home/doug/Maildir/.users.joe/dovecot.index.cache: indexid changed I usually address this by deleting dovecot.* in the directory of issue. I was thinking that I could instead just have the server delete these files and attempt to recreate them, and skipping that error message unless the re-created files are also corrupted. Any problems with this approach? Thanks, Doug

[Dovecot] panic with search

Hello, My imap daemon get SIGABRT with following message. "pool_data_stack_realloc(): stack frame changed" This is caused with cvs head sources.(and or not with my last 2 patches.)

[Dovecot] Error indexing mbox file /var/mail/seb: LF not found where expected
by Sebastian 20 Dec '04

20 Dec '04

Howdy all, Dec 19 14:24:53 dev imap(seb): Error indexing mbox file /var/mail/seb: LF not found where expected I just installed version dovecot-0.99.12.1 for the first time on FreeBSD 4.10 stable. This error occurs when I try to check my mail from a remote client and I have new messages. Here is my configuration: http://unf.be/dovecot.conf It's very close to the default install. In attempts to remedy the problem, I set "mail_read_mmaped = no", but the problem persists. I'm not sure if it's relevent, but I'm receiving mail with postfix and my mail file has lines that end with \r\n Thanks in advance for any help Sebastian -- ------------- buddhahead(a)gmail.com

[Dovecot] Auth Mechanism
by Tom Allison 19 Dec '04

19 Dec '04

Uh... I'm trying to debug an application and keep running into this: DEBUG: Sending: 1 AUTHENTICATE CRAM-MD5 DEBUG: Sent 25 bytes DEBUG: Read: 1 NO Authentication failed: Unsupported authentication mechanism DEBUG: Read: * BYE Disconnected for inactivity. So is this really asking for "digest-md5" or am I S.O.L? IIRC these are different protocols, but it's a bit early for my head to get this together.

[Dovecot] Authentication problems
by Rory Campbell-Lange 19 Dec '04

19 Dec '04

Hi. I aim to provide pop3 and imap services to a few users. At the moment I only offer imap for squirrelmail users. However, I can't login successfully for pop3. It appears to be trying to auth against PAM, rather than directly using the passwd-file. Thoughts? Thanks, Rory Config: uthenticatprotocols = pop3 imap ssl_disable = yes login = imap login = pop3 mail_extra_groups = mail auth = default auth_mechanisms = plain auth_userdb = passwd-file /etc/dovecot.passwd.conf auth_user = root auth_verbose = yes Password file: # squirrelmail imap users user1:xe9l8sIMpcTsg:1008:1008::::chroot:Maildir:/home/cmp/Maildir/user1 user2:m7VKCgWVmZYMY:1008:1008::::chroot:Maildir:/home/cmp/Maildir/user2 user3:ELh9mthLVjEG2:1008:1008::::chroot:Maildir:/home/cmp/Maildir/user3 # normal users xyz1:QtR.iN1DbL/UM:1004:1004::::chroot:mbox:/var/mail/xyz1 xyz2:y38.qLIgrvYic:1002:1002::::~/Mail:mbox:/var/mail/xyz2:INDEX=/home/xyz2 ...

[Dovecot] 1.0-test59
by Timo Sirainen 19 Dec '04

19 Dec '04

http://dovecot.org/test/ No-one had been testing 1.0-tests with Evolution? It was pretty much completely broken with messages having attachments. - test58's output stream code change were entirely wrong and caused bad breakages with mbox. - Named pipes are now treated as write-only mboxes (blocks if no-one is reading, perhaps it should timeout in a few seconds?) - FETCH BODY[n.xxx] replies were all wrong - LDAP authentication was crashing - pop3_uidl_format=%f from Andrey test60 will probably have keyword support. Its index file code is already working, with ability to set over 500k different keywords per mailbox (because message record size is limited to 65535 bytes - should be enough for everyone :). Code is still missing to notify other session about keyword changes, and storing the keywords into mbox/maildir. For mbox I can use X-Keywords header. There should probably be some configurable limit to how many keywords to set per mailbox.. Dovecot shouldn't mind if the X-Keywords header is huge, but other programs might. For maildir then.. I think I'll just implement it backwards compatible with 0.99.x, ie. store in maildir filename with a-z letters. That would make max. 26 keywords per mailbox. Except maybe I shouldn't limit it to that. The rest could be stored only in indexes. That however would make it necessary to keep indexes backwards compatible forever so data is not lost.

[Dovecot] 0.99.13-rc1
by Timo Sirainen 19 Dec '04

19 Dec '04

http://dovecot.org/rc/ I guess the RCing in 0.99.12 didn't help that much. SQL/LDAP authentication crashed because memory was freed wrong. Please test so it would actually work in 0.99.13. Also fixed SEARCH UNKEYWORD which wasn't working. Also added 1.0-test's oe-ns-eoh POP3 workaround built-in.

[Dovecot] Cygwin and index code
by Johannes Berg 19 Dec '04

19 Dec '04

As I can currently only work with windows (eek) I thought I'd try dovecot there. I already sent a patch to make dovecot compile under cygwin, but it still doesn't really work, here's part of a session that I started while my maildir was totally empty (only cur/new/tmp in ~/Maildir) $ ./imap.exe * PREAUTH [CAPABILITY IMAP4rev1 SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN NAMESPACE LOGIN-REFERRALS] Logged in as jmberg A01 SELECT INBOX imap(jmberg): Warning: Compressing cache file /home/jmberg/Maildir/dovecot.index.cache imap(jmberg): Error: open() failed with file /home/jmberg/Maildir/dovecot.index.tmp: Permission denied A01 NO Internal error occured. Refer to server log for more information. [2004-12-17 15:51:06] A02 LOGOUT * BYE Logging out A02 OK Logout completed. A second session (some files were created by the first) yields this: $ ./imap.exe * PREAUTH [CAPABILITY IMAP4rev1 SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN NAMESPACE LOGIN-REFERRALS] Logged in as jmberg A01 SELECT INBOX imap(jmberg): Error: open() failed with file /home/jmberg/Maildir/dovecot.index.tmp: Permission denied imap(jmberg): Error: rename(/home/jmberg/Maildir/dovecot.index.tmp, /home/jmberg/Maildir/dovecot.index) failed: Permission denied A01 NO Internal error occured. Refer to server log for more information. [2004-12-17 15:52:25] A02 LOGOUT * BYE Logging out A02 OK Logout completed. I think this is probably due to the indexing code opening the .tmp file and then unlinking it and trying to re-create it while the first is still open. Or something, I really am not sure. *Maybe* the index code might be made work if it creates a new temporary file-name every time it re-creates the file, but I don't understand the code well enough (yet) to give a better analysis of the problem. However, I do not think that this is really important. I certainly don't want to run dovecot on windows (I only saw cygwin compile in the todo and since I have a cygwin setup anyway I thought I'd try). The whole thing doesn't work anyway: [after correcting users, making directories, make install...] $ /usr/local/sbin/dovecot.exe dovecot: Dec 17 16:03:17 Info: Dovecot v1.0-test58 starting up dovecot: Dec 17 16:03:18 Error: login: fd_read() failed: Function not implemented dovecot: Dec 17 16:03:18 Error: close(mail client) failed: Bad file descriptor dovecot: Dec 17 16:03:18 Error: Login process died too early - shutting down dovecot: Dec 17 16:03:18 Error: imap-login: dovecot: Dec 17 16:03:18 Fatal: setrlimit(RLIMIT_DATA, 32): Invalid argument dovecot: Dec 17 16:03:18 Error: login: fd_read() failed: Function not implemented dovecot: Dec 17 16:03:18 Error: close(mail client) failed: Bad file descriptor dovecot: Dec 17 16:03:18 Error: imap-login: dovecot: Dec 17 16:03:18 Fatal: setrlimit(RLIMIT_DATA, 32): Invalid argument dovecot: Dec 17 16:03:18 Error: login: fd_read() failed: Function not implemented dovecot: Dec 17 16:03:18 Error: close(mail client) failed: Bad file descriptor dovecot: Dec 17 16:03:18 Error: imap-login: dovecot: Dec 17 16:03:18 Fatal: setrlimit(RLIMIT_DATA, 32): Invalid argument dovecot: Dec 17 16:03:18 Error: auth(default): dovecot: Dec 17 16:03:18 Fatal: setrlimit(RLIMIT_DATA, 256): Invalid argument dovecot: Dec 17 16:03:18 Error: child 2176 (auth) returned error 89 dovecot: Dec 17 16:03:18 Error: child 2192 (login) returned error 89 dovecot: Dec 17 16:03:18 Error: child 2212 (login) returned error 89 dovecot: Dec 17 16:03:18 Error: child 2232 (login) returned error 89 Maybe someone cares.
