[Dovecot] v1.1.20 vs v1.2 & v2.0
by Adam 25 May '11

25 May '11

I am currently running v1.1.20 and was wondering if there is any compelling reason to upgrade to v1.2 or v2.0? For example is there any security updates in v1.2 or v2.0 that aren't included in v1.1.20? The other major thing I would be interested in knowing is there any speed enhancements in the newer versions? I am using basic PAM Auth and Maildir mailboxes on a Linux box. Let me know if you need any more information to answer my questions. Thanks, Adam

[Dovecot] problems with debian 5.0 and thunderbird
by Steven Jones 25 May '11

25 May '11

Hi, Does anyone have a setup guide for Thunderbird and Dovecot on Debian please? Dovecot is 1.0.15 I have Dovecot running listening on 143 and I can telnet from the XP guest but Thunderbird cant or wont talk to it. I have taken the # off listen and I get a telnet reply, no firewall is configured.... Ive set thunderbird up lots so I suspect its not Thunderbird but a dovecot config I have wrong. regards

[Dovecot] libwrap does it work on in 2.0?
by a.smith＠ukgrid.net 24 May '11

24 May '11

Hi, I noticed recently that libwrap (TCP Wrappers) is supported, although disabled by default, in the current Dovecot 2.0 but doesn't seem to be mentioned anywhere on the wiki. Is this working well/at all? Anyone care with experience using this care to share their experiences? My OS is FreeBSD, I noticed on some Linux distributions there may be issues, but this won't affect my installation. thanks Andy.

Re: [Dovecot] How to stop mail_executable from cwd to ~home

I'm all for that since I don't seem to have any need for a home directory. Any idea of how to do it with a passwd-file userdb backend? I also tried to override home directory with userdb { driver = passwd-file args = /etc/passwd home=/bundled/home/$n } but that didn't work out too well. Or is this feature a rephrasing of the current topic thread "Global fields for passwd-file database". Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] delegation of admin rights
by Ariel Biener 23 May '11

23 May '11

Hello, We're a rather largish university (largest in Israel), with some 60-70k users, using Dovecot 1.2.14 (we're cautious about moving to 2.0.x for now). We need to provide admin rights to faculty computer/IT staff, so they can have access to the mailboxes of their respective users. We use LDAP as an authentication/authorization backend. Currently, dovecot has a "master user" which can access all mailboxes. I am looking for a solution, preferably within dovecot, to create a delegation type of administration, allowing certain users to access the mailboxes of other users based on an LDAP filter or LDAP attribute value. If possible, allowing per protocol access(that is, I would like to give them IMAP access and not POP3) and within IMAP allowing only to view a mailbox, but not to change it, that would be even better. Does anyone on this list know of any IMAP proxy providing such abilities, and also, would the Dovecot team consider this as a candidate for a request for enhancement ? This would be very useful in a delegated administration environment, like most larger organizations, hosting & ISP, and other environments where delegation is an important and very much needed ability. thanks a bunch, -- Ariel -- Ariel Biener e-mail: ariel(a)post.tau.ac.il PGP: http://www.tau.ac.il/~ariel/pgp.html

[Dovecot] Crash test :)
by kjonca＠o2.pl 23 May '11

I'm considering to move my mails from maildir/mbox to mdbox. One of my doubts is: how can I restore my mails when something terrribly wrong happens. I understand that I should use doveadm import "backup_location" "mailbox" all. So I try to import with: doveadm -v import "sdbox:~/Mail/dbox-temp/spamcop/reports/" "#Dbox/spamcop/reports" all #Dbox namespace were defined as: --8<---------------cut here---------------start------------->8--- namespace { hidden = no inbox = no list = yes location = mdbox:~/Mail/Dbox prefix = "#Dbox/" separator = / subscriptions = yes type = private } --8<---------------cut here---------------end--------------->8--- dbox-temp were defined earlier as --8<---------------cut here---------------start------------->8--- namespace { hidden = no inbox = no list = yes location = sdbox:~/Mail/dbox-temp separator = / subscriptions = yes type = private } --8<---------------cut here---------------end--------------->8--- 1. when I specified for example sdbox:~/Mail/dbox-temp/spamcop/reports/ doveadm search mails under ~/Mail/dbox-temp/spamcop/reports/mailboxes/INBOX/dbox-Mails/ - am I missing something from documentation? (I expected rather ~/Mail/dbox-temp/mailboxes/spamcop/reports/dbox-Mails) 2. when I move dbox-Mails to proper place I got: doveadm(kjonca): Error: sdbox /home/kjonca/Mail/dbox-temp/spamcop/reports/mailboxes/INBOX/dbox-Mails: Invalid dbox header size doveadm(kjonca): Error: sdbox /home/kjonca/Mail/dbox-temp/spamcop/reports/mailboxes/INBOX/dbox-Mails: Invalid dbox header size And nothing were imported.
