[Dovecot] Script to install dovecot 1.2 plus Managerootsieve to CentOS5.2
by Bruce A. Mallett 07 Apr '09

07 Apr '09

I have no idea if this is of interest to anyone but it might save you some work .. I created a script that will install Dovecot 1.2-rc2 (currently) to a CentOS5.2 installation complete with Stephan Bosch's Managesieve, postfix, virtual users, LDAP, and LDAP personal address books. Oh right! .. and Squirrelmail plus various plugins (change LDAP password, LDIF import, Avelsieve). Also self-signed certificates are created from data supplied in a configuration file. I've stuck the required files here: http://www.nightstorm.com/~bam/CentOS5.2/ I did an install to a 32 bit CentOS so it has worked at least once on that architecture. It *should* work on a 64 bit as well (I provide the RPM) but I've not personally tested it. I am by no means an expert on any of this stuff (particularly the security aspects), so I'd certainly welcome any suggestions for ways to improve on the installation, the script, life, the universe, ... ;-) - Bruce

[Dovecot] v1.2: can't access other users shared INBOX
by Sascha Wilde 06 Apr '09

06 Apr '09

Hi *, when a user A shares his INBOX with another user B, the user B can't access its content: User A: g getacl INBOX * ACL INBOX A(a)example.com lrswipkxtecda B(a)example.com lrswipkxtecd g OK Completed User B: l list "" "*" * LIST (\Noselect \HasChildren) "/" "user" * LIST (\Noselect \HasChildren) "/" "user/A(a)example.com" * LIST (\HasChildren) "/" "INBOX" * LIST (\HasNoChildren) "/" "INBOX/Gesendet" * LIST (\HasChildren) "/" "user/A(a)example.com/foobar" * LIST (\HasNoChildren) "/" "user/A(a)example.com/INBOX" l OK List completed. s1 select "user/A(a)example.com" s1 NO [CANNOT] Invalid mailbox name s2 select "user/A(a)example.com/INBOX" s2 NO [NONEXISTENT] Mailbox doesn't exist: INBOX Actually there are two bugs to observe here: 1) "user/A(a)example.com" really should be accessible to user B. Why is it listed with "\Noselect"? 2) "user/A(a)example.com/INBOX" does not exist, so the error message is correct, but why does it appear in the listing in the first place? cheers sascha -- Sascha Wilde OpenPGP key: 4BB86568 http://www.intevation.de/~wilde/ http://www.intevation.de/ Intevation GmbH, Neuer Graben 17, 49074 Osnabrück; AG Osnabrück, HR B 18998 Geschäftsführer: Frank Koormann, Bernhard Reiter, Dr. Jan-Oliver Wagner

[Dovecot] Implementation of editheaders in dovecot
by Konstantin Lepa 06 Apr '09

06 Apr '09

Hello. I wrote the hook function for deliver. I want to add support of editheaders in the plug-in for dovecot. For this purpose I wrote the function rarules_get_stream. Remover of headrs works properly, but adding does not work. I took Timo Sirainen's advice from http://markmail.org/message/skb6arnll5gaopdr . Do I use a correct way of creation of a message? I give backtrace and a part of my code.
