[Dovecot] Using Dovecot as Asterisk PBX voicemail server
by Kenneth Porter 13 Nov '07

13 Nov '07

I'm reading the Asterisk book, 2nd edition, and it describes how one can set up voicemail to be delivered by IMAP to a voicemail folder. Asterisk can monitor flags on the folder so that the "message available" light on one's phone tracks the state of the "read" flag in the folder. One can either dial in for one's voicemail or listen to it from one's favorite IMAP client. (Dovecot is mentioned in the book.) I'm wondering how one would set up auth for this? Asterisk needs to log in to the account to deliver the voicemail and to check its state, but I wouldn't want to put everyone's mail password in plaintext in Asterisk's voicemail.conf file. Would I set up a separate IMAP account for each user to hold their voicemail, and use simple passwords (such as the PIN they use for phone access to voicemail) in the Asterisk config? Or is there a way to set up Dovecot to allow a second user to login to a specific IMAP folder in all accounts, in the same way the local delivery agent has write access to all users' mailbox? Google's page for the book: <http://books.google.com/books?id=vtQxJ3oSm64C&dq=asterisk+book> Dovecot mentions: <http://books.google.com/books?id=vtQxJ3oSm64C&dq=asterisk+book&q=dovecot#se…>

[Dovecot] namespace public folders
by Nikolay Shopik 13 Nov '07

13 Nov '07

Hi list, Here is thing im trying to accomplish. I would like to setup public folders which resposible for delivering mails for some speical addresses like info(a)example.com. And it will be perfect if "seen" status for this folder will be saved per user. I mean if one user read message and set it as read other user should see it still as unread. As I far i know there some limitation in 1.0 tree but not in lates 1.1. My question is can I do such setup with dovecot+postfix. Im really appreciate for simple examples how can i accomplish this kind setup if it possible :)

[Dovecot] Caching?
by Bjørn T Johansen 13 Nov '07

Any way to minimize the number of sql statements that dovecot do? (and I tried adding userdb prefetch { } but number of sql calls are still the same) Am I doing something wrong or?

[Dovecot] v1.1.beta8 released
by Timo Sirainen 13 Nov '07

13 Nov '07

http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta8.tar.gz http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta8.tar.gz.sig Changes since beta7: - Added a new "raw" mail storage backend which allows opening files/streams as single mail mailboxes. deliver uses this now instead of opening the incoming mail as a mbox. So deliver should be now faster and it doesn't anymore remove Dovecot's private mbox headers if you're not using mbox. - Cache file tracks message expunges again - All kinds of other fixes - Some optimizations I think we're getting closer to v1.1 RCs.

[Dovecot] Missing deliver
by Sean Smitz 13 Nov '07

13 Nov '07

I've installed Red Hat Enterprise Linux 5 on a new server. I'm configuring sendmail and dovecot; however, /usr/local/libexec/dovecot was not created when I installed the dovecot rpm (rpm -Uvh dovecot-1.0-1.2.rc15.el5.x86_64.rpm). The problem is I can't find the deliver executable which is supposed to be in this directory. Any help would be appreciated.

[Dovecot] login_process_size too small on x86_64 Fedora/RHEL
by Tomas Janousek 12 Nov '07

12 Nov '07

Hello, as described in [253363], login_process_size of 32M is not enough on 64-bit versions of Fedora and RHEL (and possibly other distributions as well). [253363] https://bugzilla.redhat.com/show_bug.cgi?id=253363 As I understand it, there's an intersegment gap between read-only/executable and writable segments of shared libs. That's probably a security feature or something. I found a similar issue here[1], if anyone wants a comment from someone who understands it. [1] http://gcc.gnu.org/ml/libstdc++/2006-12/msg00033.html Shall we just increase login_process_size or make it arch-dependent or something? Regards, -- Tomas Janousek, SW Engineer, Red Hat, Inc.

[Dovecot] Secure authentication?
by Bjørn T Johansen 12 Nov '07

12 Nov '07

I have enabled SSL support for my dovecot installation but if I enable secure authentication in my MUA, I get an error from dovecot telling me that this is not supported.. Is this because dovecot does not support this or am I missing some config?

[Dovecot] dovecot 1.1b7: mail-cache-lookup.c: line 68: unreached
by Adam McDougall 12 Nov '07

12 Nov '07

I have since upgraded to 1.1b8 but this morning my attention was called to this error from 1.1b7: Nov 11 06:35:17 hill dovecot: IMAP(voice): file mail-cache-lookup.c: line 68: unreached Nov 11 06:35:17 hill dovecot: child 70673 (imap) killed with signal 6 Nov 11 06:35:17 hill dovecot: IMAP(voice): Connection closed bytes=262/25869 I can't say for sure but it was probably a squirrelmail connection. It wasn't me, and I wasn't even awake at the time so I don't know how to reproduce it.
