[Dovecot] Shared mailboxes and acl
by Juan C. Blanco 07 May '11

07 May '11

Hello, I've finally upgrade to dovecot 2.0.12 and I'm doing some test with shared mailboxes and acl. I've read http://wiki2.dovecot.org/SharedMailboxes/Shared and changed the dovecot config as recommended, I'm using Horde/IMP as imap_acl client Seems that the acl files in user mailbox where updated correctly. I've defined also a shared mailbox dictionary and if I've understood right from the wiki page this file is supposed to be also updated with the imap_acl commands, is this right? In my case this file is never updated, I don't know if this file must have any special format or is a simple text file. Any help will be appreciated Regards Juan C. Blanco

Re: [Dovecot] May 05 07:20:21 imap: Warning: Time jumped forwards 16 seconds

Hello, You say ntpd is running. Is it running as a daemon ? AFAIK, to keep good time on a linux machine inside the network, you need to run "ntpdate" and not "ntpd". I had _exactly_ the same problem and I was running an ntp daemon. I wasn't actually syncing to anything. So,I did some searching and found out that I need to run "ntpdate ntp.server.fqdn", then add this same line to cron.

[Dovecot] Encoding dovecot keywords
by Алексей Сундуков 06 May '11

06 May '11

Hello. If mailbox name include non latin chars, dovecot save it encode to modification UTF-7. Example "тест" convert to "&BEIENQQ6BEEEQg-". If replace & to + I can decode it: <?php $str = '+BEIENQQ6BEEEQg-'; echo iconv('UTF-7', 'UTF-8', $str); ?> But I can't understand what encoding use dovecot for keywords? I set "тест" (number 5) keyword: cat dovecot-keywords 0 &bcienqrbbeiepgqybdaetw-_&bdwenqrcbdoema- 1 test 2 $label1 3 $label2 4 $label3 5 &beienqq6beeeqg- but "&beienqq6beeeqg-" do not convert to "тест". Why?

[Dovecot] Bug Report: Failure delay config is ignored
by Kevin Goodsell 04 May '11

04 May '11

I have a set of automated tests for a system that can authenticate a user by forwarding authentication details to a server. That is, in order to authenticate a user, this system logs on to, e.g., an IMAP server using the credentials supplied by the user to verify the correctness of those credentials. I've been using dovecot as the authentication server to test IMAP, IMAPs, POP3, and APOP. To run the tests (most of which are authentication failures), I configure dovecot without authentication failure delays, since obviously I don't want to wait several minutes for the tests to finish. Setting the configuration variable auth_failure_delay to 0 worked fine in Dovecot 1.2, but since Debian updated to Dovecot 2.0 it no longer works. The tests take a very long time to run. I tried changing my passwd file to include nodelay=y, but this only works in a very limited way. For the set of tests which use the correct username, but an incorrect password, this successfully disables the failure delay. However, for the set of tests which use incorrect usernames (names not found in the user database or the password database, and which therefore don't have the extra nodelay field), the failure delay still occurs. There seems to be at least two problems here. The first is that it isn't clear what effect auth_failure_delay has. The comment in the sample config file just says "Time to delay before replying to failed authentications", which is certainly an incomplete description if not totally inaccurate. This setting seems to be completely unmentioned in the 2.0 wiki. The second problem is that the nodelay extra field can only be applied on a per-user basis. There doesn't seem to be any way to apply it to all users, or to apply it to authentication attempts for non-existent users. It seems to me that the failure delay that is actually used should either be 1) the actual value of auth_failure_delay (ideally with some random variance for extra security, but recognizing 0 as meaning disabled) or 2) some multiple of auth_failure_delay, where the multiplier increases with subsequent failures up to some max delay, with 0 still giving no delay. Config information follows. Thanks. -Kevin $ dovecot -n # 2.0.12: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-686 i686 Debian wheezy/sid auth_debug = yes auth_failure_delay = 0 auth_mechanisms = plain apop auth_verbose = yes listen = 127.0.0.1 log_path = /var/log/dovecot mail_location = maildir:~/Maildir passdb { args = /etc/dovecot/passwd driver = passwd-file } protocols = " imap pop3" ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } $ cat /etc/dovecot/passwd testuser:{PLAIN}testpassword::::::nodelay=y

[Dovecot] Forwarding loop
by Brian Mihulka 04 May '11

04 May '11

I used to filter my mail through gmail with the following sieve rule. if not header :contains "X-Forwarded-To" "bmihulka(a)hulkster.net"{ redirect "bmihulka(a)gmail.com"; } With the gmail account set to forward to bmihulka(a)hulkster.net After upgrading to dovecot 1.2.9 and postfix 2.7.0 from whatever was with debian etch. I get a forwarding loop error. I don't know if this is a dovecot issue or postfix issue so I'm starting here. If anyone has any ideas or a better place to ask about this please let me know. Thanks Brian Mihulka
