Did you migrate their mailboxes from another server? And store mail accounts in MySQL?
We have another user reported the same issue with migrated mailboxes and MySQL backend. You can find solution to fix it in iRedMail upgrade tutorial, from 0.7.3 to 0.7.4 (will be released tomorrow). http://www.iredmail.org/wiki/ (Sorry it's hard for me to paste direct link of this upgrade tutorial with this mobile device)

Hi again.
After several tests, I have discovered that e-mail accounts disappear when deleting emails from RoundCube.
When an user deletes a mail from inbox folder, in RoundCube, his account dissapear in iRedAmin Pro, so he can't log in again.
I see, in vmail database, in the table named 'mailbox', that this user exists, but some fields are empty (password, name, maildir, domain, and local_part).

I'm running iredmail 0.7.4-rc3, and I don't know how to upgrade to 0.7.4 stable, without risk of data or settings loss. Is there a quick and safe way to do it?

Thx.

==== Provide basic information to help troubleshoot ====
- iRedMail version: 0.7.4
- Linux/BSD distribution name and version: ubuntu Server 11.10 64 bits
- iRedAdmin-Pro-MySQL-1.3.1
- Any related log? Log is helpful for troubleshooting.

Well, now I have my Ubuntu server 11.10 with iRedMail 0.7.4 and iRedAdmin-Pro-MySQL-1.3.1. It seems it's working fine. However, Policyd is disabled. In policyd section into my 'settings.ini' file, I have these values:

enabled = false
host = 127.0.0.1
port = 3306
db =
user =
passwd  =

If I turn enabled=true, what values are valid in db, user and passwd?
I see in settings.ini.mysq.sample file these values:

db = policyd
user= policyd
passwd = passwd

but there is no database with that name in MySQL.

Is there any problem to use Policyd with iRedMail 0.7.4 and iRedAdmin Pro MySQL 1.3.1?

I've configured external access and I can connect to webui, but when I click in any option I get this error:
"Error connecting to Policyd v2 DB: could not find driver"
I have the correct values for db, username and passwd in /etc/cluebringer/cluebringer.conf
What driver I need?

I have the 'libdbd-mysql-perl' and 'php5-mysql' installed.
and these processes are running:
/usr/bin/perl /usr/sbin/cbpolicyd --config=/etc/cluebringer/cluebringer.conf
/usr/bin/perl /usr/sbin/cbpolicyd --config=/etc/cluebringer/cluebringer.conf
/usr/bin/perl /usr/sbin/cbpolicyd --config=/etc/cluebringer/cluebringer.conf
/usr/bin/perl /usr/sbin/cbpolicyd --config=/etc/cluebringer/cluebringer.conf
/usr/bin/perl /usr/sbin/cbpolicyd --config=/etc/cluebringer/cluebringer.conf

This is the log entry when I try to click on any option:

www.dominio.com:80 87.219.157.215 - - [06/Feb/2012:19:07:12 +0100] "GET /cluebringer/checkhelo-whitelist-main.php HTTP/1.1" 200 310

I see that in /var/log/apache2/others_vhosts_access.log

access.log and error.log don't report anything.

Also, I have a lot of errors in /var/log/cbpolicyd.log. All errors are the same:

"Use of uninitialized value $email_domain in lc at /usr/lib/postfix-cluebringer/cbp/policies.pm line 476, <_READ> line 26877."

I'm running postfix-cluebringer 2.0.10-1
