[Dovecot] Annotation plugin for dovecot
by Bernhard Herzog 02 Oct '08

02 Oct '08

Hi, as part of an effort to make dovecot usable as the IMAP component in the Kolab Groupware system <http://kolab.org/>, we've started to develop a plugin that implements the IMAP METADATA extension. The plugin is still under development and development is focused on the plugin's use in Kolab, so it will at first only implement what's immediately needed to achieve that goal. The plugin is available as a mercurial repository at http://hg.intevation.org/kolab/dovecot-metadata-plugin/ More information about the current status of the plugin is available in the README file in the sources. Regards, Bernhard

[Dovecot] Unable To Move IMAP Folder (Dovecot)
by Carlos Williams 02 Oct '08

02 Oct '08

I have a user who has a folder in his Maildir/ called "test" /home/user/Maildir/.test This folder shows up as a sub folder to his Inbox on his Thunderbird client and I tried using the "cp" command to move this over to my Maildir/ directory on the same server and when I launch Thunderbird, that folder is not visible for me. I made sure permissions are correct and even reloaded Dovecot. mail:/home/user/Maildir# cp -R .test/ /home/me/Maildir/ mail:/home/user/Maildir# chown -R me:users .test/ The permissions and ownership seem to be identical to all the folders I created as subfolders myself but for some reason, I can NOT see "test/". Does anyone know what I am doing wrong?

[Dovecot] Why my Evolution cannot delete emails in dovecot IMAP folder?
by Igor Chudov 02 Oct '08

02 Oct '08

I use Ubuntu Hardy, get mails locally and run dovecot listening on localhost. I run Evolution and have it connect to dovecot, so that I can access my mail in IMAP and be able to use mutt from remote. So far so good. It works. However, my problem is that Evolution cannot delete any messages. That is, when I click DELETE in Evolution, Evolution no longer sees the message , but the message is still there. That's not what I want, when deleting messages I want them to go away from Inbox. How can I do it? thanks i

[Dovecot] ACL plugin
by Matvey Soloviev 01 Oct '08

01 Oct '08

Hello, I am working on implementing support for the RFC4314 ACL management commands and responses in the ACL plugin included with dovecot 1.1.2. (I verified the error persists with 1.1.3 though.) While the described objective is still in the works, I have stumbled upon what I believe to be a critical issue with the handling of negative rights in the present ACL plugin - to be precise, the cache component of it handles them in the exact same way as it does positive rights, thus granting rather than retracting the individual privileges. To fix this, go to src/plugins/acl/acl-cache.c:391. The line and the one following it should read p[j] |= obj_cache->my_neg_rights[i]->mask[j]; Replace that to read p[j] &= ~obj_cache->my_neg_rights[i]->mask[j]; I hope this information is useful. Regards, M. Soloviev

[Dovecot] disbale to responded to an unrequested SSL Certificate
by Andre Hübner 01 Oct '08

01 Oct '08

Hi dovecot-list, just a easy question today ;) Customer did on Server a PCI-Test to test security to fit worldpay requirements. They found a critical risk at pop3s. (and some other things) This is the Textmesage: ############ Family: Remote Shell Access Critical 993/tcp 11875 Description: The remote host responded to an unrequested SSL Certificate. The remote SSL server should have sent back an Error message. This may indicate that the server is vulnerable to a remote flaw in the way that it handles unrequested certificates. You should manually inspect the SSL Server's configuration ############ Background is that we use a wildcard-cert which is installed on ervery machine and fits to servername. So you have to use the accredited Hostname/Servername to make clean ssl connection pop3s/imaps without warnings etc. Problem should be that server sends no error when requested with other hostname. This is significant part from dovecot.conf protocols = imap imaps pop3 pop3s ssl_disable = no ssl_cert_file = "/path/to/*.myhost.com.crt" ssl_key_file = "/path/to/*.myhost.com.key" ssl_ca_file = "/path/to/*.myhost.com.bundle.crt" Is there a Config-Option to send error when ssl-connect ist not established to in cert accredited Hostname/Servername ? Did not found something like this or did not really understand function of the options. I do not know backgrounds to this issue. Cant decide if it would be a security risk or disproportionated wishes of securityexperts but i want to satisfy this costumer. How to handle thos? Thank you Andre

[Dovecot] quota warnings clarification
by Ian B 01 Oct '08

01 Oct '08

I spent a long while trying to get quota warnings working with v1.1.3 on Centos5 before almost giving up. I configured everything as per the instructions on the Quota wiki page however no warning emails were being generated when I tested & no debug messages in the log to give any clues as to what I was doing wrong. It turns out I wasn't doing anything wrong, but just misunderstanding at what point the warnings are generated. The warning email appears to only be generated when a message is moved from one folder to another. I was expecting the warning to be generated when the INBOX was simply opened & viewed! Is this how it is supposed to work? If so, perhaps a note of clarification could be added to the wiki page? Make the switch to the world's best email. Get Yahoo!7 Mail! http://au.yahoo.com/y7mail

[Dovecot] Managesieve Quota
by Seth Mattinen 01 Oct '08

01 Oct '08

Has anyone (is anyone) working on adding quota support to dovecot's managesieve server? I was thinking about giving it a shot myself and I'd hate to duplicate work. It would be something very basic like a max bytes setting and the total sieve storage per user isn't allowed to exceed it. ~Seth
