Plugin hooks in login process
Hi all;
I've setup dovecot (2.1.10) in a cluster configuration. We have two servers
acting as frontend which authenticates users and proxy them to other two
servers which handles the "real" work.
Users credentials are on a mysql cluster; we have one master, in which
read/write queries are processed, and many replicated slave, which process
read-only queries.
The frontend

post-login script and original remote ip in proxy mode
Hi,
I am running dovecot on 3 qmail-ldap server backend.
dovecot configured to use auth_pop3 wrapper for authentication.
Users logins to the qmail-ldap pop3&imap pools randomly. If a user is
mailhost is not the connected server, dovecot proxies the connection to the
user mailhost. In this case, I can not get the original client IP address
via post-logins script on user host. I see only the

Proxy connection timeouts
We are seeing a few (0-15) proxy failures like the following out of ~3m
successful proxied connections a day. Average session creation load over
our peak hour is about 47/sec. The backend servers aren't logging
anything that would suggest any internal problem like insufficient
processes to handle the load. It doesn't seem to happen when
utilization is lowest at night.

Changing Password Schemes
Good Day,
I have been following this tutorial without much luck -
http://wiki2.dovecot.org/HowTo/ConvertPasswordSchemes#CA-26af2b83a43b8100522c57565773f605c21f2f27_1
It is obvious to me that I am not following the instructions correctly
and need to be shown what I am misunderstanding.
I have an old postfix + dovecot + Roundcube mailserver

Technically creating and encrypting folder key does not require decrypting user's private key. All folder keys are encrypted with user's public key.

Changin password in LDAP
We are using now dovecot 2.0.21 with open-ldap, but this situations has already taken a quite long time. When user changes the password, we have to reload dovecot every time, otherwise the change is ignored and dovecot sees only the old password. Any ideas where the problem might exist?
Conf:
# 2.0.21: /etc/dovecot/dovecot.conf
# OS: Linux 2.6.18-308.24.1.el5 i686 CentOS release 5.9 (Final)

Can I set the proxy server and authentification from within R?
Hi,
I am using Tinn-R and somehow I cannot point it to
start a R shortcut with http_proxy settings including
authentification. It always shows the .exe.
Is there any way to set the proxy from within R or any
other ideas how to do it?
I am using R 2.4 for Windows.
Thanks a million,

doveadm purge -A via doveadm-proxy director fails after some users
Hi,
we have configured userdb and passdb in the director and try to
iterate all users and pass the "purge" command via doveadm proxy to
port 19000 on the correct director backend host.
A single purge -u username at example.org via doveadm-proxy works correctly,
but iterating over some users with -A fails.
Note: users/domains have been anonymized in output:

Moving to new password scheme
dovecot is setup on a system with MD5-CRYPT password scheme for all users, and I would like to update this to something that is secure, probably SSHA256-CRYPT, but I want to do this seamlessly without the users having to jump through any hoops.
The users are in mySQL (managed via postfixadmin) and the mailbox record simply stores the hash in the password field. Users access their accounts though

Hi

logs.

is it possible that i recieve a remote ip of user client on proxied internal
machine, cause i have only the proxy one, and that date is not a relevant to

Authentification using Linux user/password
I am writing an in-house web application with RAILS and I want users to
log-in to the application before they can do anything. Since all users
already have an accont on the linux machine where the web application
will be running, I''d like to use these accounts for authentification.
Is there a way in Ruby/RAILS to authenticate a user/password pair

Problem is for that this is a new user. The new user has no private key. I
need for generating that private key. It do not the sense encrypts
something using a key public if there is no private key. Both key public

dovecot-proxy with managesieve, director and backend dovecot imap
hi all,
I've been tasked to add sieve/managesieve to an existing dovecot cluster
running 2.1.7 on debian wheezy which is made up of 2 dovecot-proxy hosts
as directors and some back end dovecot imap hosts all running the same
version.
My problem is that I thought to put the service on the director/proxy
hosts since they wouldn't have too much load on it, but when I do I get

updating via CRAN and http
Hello,
thanks for the tips on updating packages for 1.8.0. The updating is a real
problem for me, since I've to do it sort of manually using my web-browser or
wget. I'm behind a firewall that requires http/ftp authentification (username
and passwd) for every request it sends to a server outside our intranet.
Therefore all the nice tools for automatic updating (cran, cpan ...) don't
