[Dovecot] 100% CPU utilisation
by Zoong Pham 05 Sep '04

05 Sep '04

Dovecot (0.9.11) consumes 100% CPU utilisation when accessing (either pop or imap) one of my mailboxes. It doesn't happen with other mailboxes. The mailbox has about 500 mails while others have many more. They are all in mbox format. OS: OpenBSD-3.5 with all patches MTA: Sendmail-8.12.11 It happened with other RCs of dovecot-0.9.11 Configured as: ./configure --without-pam --without-shadow --without-vpopmail --localstatedir=/var --with-ssldir=/etc/ssl --with-ssl=openssl There is no strange information in /var/log/maillog except the normal ones like: Sep 6 10:12:40 onion imap-login: Login: zoong [127.0.0.1] The pop or imap clients (mutt and squirrel-1.4.3a) just stay at "opening INBOX ...". mutt can open directly the mailbox without any problem. I rebooted the server and problem still happening. Can someone advise how to find out what's wrong here? I guess there is some kind of corruption within the mailbox.

[Dovecot] Plaintext Authentication from Localhost
by Paul C. Bryan 05 Sep '04

05 Sep '04

Hi: It appears that at least at one time, Dovecot supported plaintext authentication from localhost, even if disable_plaintext_auth = yes. To wit, the example configuration file reads: # Disable LOGIN command and all other plaintext authentications unless # SSL/TLS is used (LOGINDISABLED capability). Note that 127.*.*.* and # IPv6 ::1 addresses are considered secure, this setting has no effect if # you connect from those addresses. #disable_plaintext_auth = yes On brief inspection of the code, there doesn't seem to be any such support. This is corroborated by the fact that 0.99.10 (Debian package) behaves by disallowing plaintext authentication via connections on localhost. This is a particularly useful feature, as local webmail clients can safely authenticate via the local interface without requiring secure authentication. So, the question is, is Dovecot supposed to support plaintext auth via localhost even if disallowed in dovecot.conf? If so, any suggestions as to what I may be doing wrong? Yours truly, Paul C.

[Dovecot] pam_access
by Programmer 04 Sep '04

04 Sep '04

I've discoverd when I add the line pam_access for access authentication, It always denys a login, even when access.conf accepts everything. I've tested this with other programs, and they work okay. Any ideas?

[Dovecot] link() problem with dovecot-imapd
by James Ray 04 Sep '04

04 Sep '04

I'm having a few problems with dovecot-imapd (installed from debian unstable) and am after some much needed help, all is set up and configured, except for this final problem of when I try and move or copy a message from one Maildir to another. I have the option "maildir_copy_with_hardlinks = no" in the the dovecot.conf file but it still seems to be trying to link() the file instead of doing a proper copy. There is a log fragment below for when I try to do a move, the FS that my Maildir is on doesn't support link() hence the problem. It seems to be doing a proper copy to get it into the tmp/ part of the Maildir and then a link() to put it in new/. Any ideas on how to cure this? Log output;l -- Sep 2 18:44:29 indulgence imap(jamesr): link(/home/jamesr/Mail/Maildir/.INBOX.Trash/tmp/1094147066.P2339Q0M915274.indulgence, /home/jamesr/Mail/Maildir/.INBOX.Trash/new/1094147066.P2339Q0M915274.indulgence:2,Sa) failed: Operation not permitted James 'BR' Ray - EMail : jamesr(a)pethippo.co.uk (Primary) - EMail : j.ray(a)herts.ac.uk (University) - Web : http://www.pethippo.co.uk/ - PGP : http://www.pethippo.co.uk/in.php/pgp

RE: [Dovecot] file ostream-file.c: assertion failed with v1.0-test38
by dovecot 04 Sep '04

04 Sep '04

Hi, > IMAP(username): file ostream-file.c: line 105 > (update_buffer): assertion failed: (size <= used) Sep 4 Same error occurs here, using test38 on Fedora Core 1. For me, the error occurs only using Outlook (2003 in my case). Horde's WebMail client IMP and OpenNMS' IMAP poller work fine though. Reverting back to test32 helped, after I found out about a recent change in ostream-file.c in CVS aroung August 15. BTW, test32 fixes the mbox 'empty lines at beginning of file' corruption problem someone reported here lately too. Regards, Martin

[Dovecot] "not listening" errors fdpass.c
by christian sherwood 03 Sep '04

03 Sep '04

I'm getting a flood of errors that look like: Sep 3 13:27:02 localhost dovecot: login: received another "not listening" notification (if you can't login at all, see src/lib/fdpass.c) every few minutes. Versions: Dovecot: 0.99.10.9 Exim: 4.34 Debian Linux 2.6.8-1-686-smp Squirrelmail: 1.4.3a Although the majority of users (99%) have no problems logging in and reading their mail, occasionally one user gets timeouts when trying to access their mailbox, seems to correlate with the errors. I can't locate fdpass.c, so what does this error indicate?

[Dovecot] isync with dovecot
by tino.keitel＠gmx.de 03 Sep '04

03 Sep '04

Hi folks, I use isync, an IMAP sync tool (Debian package isync 0.9.2-2) together with dovecot (dovecot-imapd 0.99.10.8-0.backports.org.1). Everytime when isync wants to upload a new mail from the client to the server I got messages like this: Mailbox outbox Selecting IMAP mailbox... >>> 16 SELECT "outbox" * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 1580 EXISTS * 0 RECENT * OK [UIDVALIDITY 1092995697] UIDs valid * OK [UIDNEXT 1581] Predicted next UID 16 OK [READ-WRITE] Select completed. 1580 messages, 0 recent Reading IMAP mailbox index >>> 17 UID FETCH 1:* (FLAGS) * 1 FETCH (UID 1 FLAGS (\Seen)) * 2 FETCH (UID 2 FLAGS (\Seen)) [...] * 1579 FETCH (UID 1579 FLAGS (\Seen)) * 1580 FETCH (UID 1580 FLAGS (\Seen)) 17 OK Fetch completed. Synchronizing Uploading messages.>>> 18 APPEND outbox (\Seen) {360} + OK 18 OK Append completed. >>> 19 UID SEARCH HEADER X-TUID 4136367cd15e45705 * SEARCH IMAP error: incomplete SEARCH response 19 OK Search completed. warning: no UID for new messge 1094071902.22258_2.thinkpad:2,S 1 messages. Fetching new messages... 0 messages My concern is the line "IMAP error: incomplete SEARCH response". I already saw this mesage with old versions of courier-imap, which won't return an APPENDUID tag so the client doesn't know which UID will be used for the uploaded message (this was the explanation I got). Is there any way to get dovecot to return the UID when a message is uploaded? Regards, Tino
