[Dovecot] Dovecot quota support
by Alton Yu 07 Sep '04

07 Sep '04

Sorry if this question has already been answered. I'm just thought that maybe I could get an answer here faster than my research. I'm currently using squirrelmail and there's a plugin that supports quota compatible with Courier. Does dovecot have the same support? Thanks!

Doesn't happen to all users and doesn't seem to be dependent on size of Maildir, sending SIGTERM makes it go away and then the user opens the mailbox again and I see normal CPU usage. However 3-4 hours later it will happen again. Using FreeBSD 4.9 and dovecot-0.99.10.4, postfix 2.0.18 as MTA. If theres any other info that would be useful (this is probably the most vauge description I can manage, but its all the info I have) then let me know and I can provide. Ta Jamie

I have some experience with OBSD, squirrel, vpopmail and dovecot. In my experience it would hang like that if squirrel was set up to sort/thread (or whatever the settings was named). try to turn such things off and see if that helps. -- Lasse Danielsen lasse(a)danielsen.tk -- No part of this message may reproduce, store itself in a retrieval system, or transmit disease, in any form, without the permissiveness of the author. > > Dovecot (0.9.11) consumes 100% CPU utilisation when accessing > (either pop or imap) one of my mailboxes.

06 Sep '04

Hello. Today one of my users has returned from vacation and his mailbox has grown to 67 Mbyte in 1705 e-mails. dovecot can't index this mailbox with this message (i've changed username with 'xxx'): pop3-login: Sep 06 10:03:43 Info: Login: xxx [172.16.4.9] pop3(xxx): Sep 06 10:03:43 Error: Error indexing mbox file /var/mail/xxx: LF not found where expected pop3(xxx): Sep 06 10:03:43 Error: Error indexing mbox file /var/mail/xxx: LF not found where expected pop3(xxx): Sep 06 10:03:43 Warning: I/O leak: 0x8050600 (0) pop3(xxx): Sep 06 10:03:43 Warning: I/O leak: 0x80858f0 (1) pop3(xxx): Sep 06 10:03:43 Warning: Timeout leak: 0x8065b90 Is it a bug in dovecot?

[Dovecot] v0.99.11 released
by Timo Sirainen 06 Sep '04

06 Sep '04

v0.99.11 2004-09-04 Timo Sirainen <tss(a)iki.fi> + 127.* and ::1 IP addresses are treated as secured with disable_plaintext_auth = yes + auth_debug setting for extra authentication debugging + Some documentation and error message updates + Create PID file in /var/run/dovecot/master.pid + home setting is now optional in static userdb + Added mail setting to static userdb - After APPENDing to selected mailbox Dovecot didn't always notice the new mail immediately which broke some clients - THREAD and SORT commands crashed with some mails - If APPENDed mail ended with CR character, Dovecot aborted the saving - Output streams sometimes sent data duplicated and lost part of it. This could have caused various strange problems, but looks like in practise it rarely caused real problems.

[Dovecot] 100% CPU utilisation
by Zoong Pham 06 Sep '04

06 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 06 Sep '04

06 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. Bryan email(a)pbryan.net
