I’ve followed the steps described in here : http://wiki.qmailtoaster.com/index.php/CentOS_5_QmailToaster_Install to install Qmail Toaster on Centos 5.5.

If you access the isoqlog and get this error:
Forbidden?You don’t have permission to access /qlogs-toaster/ on this server.

After you do some email traffic run this :

sh /usr/share/toaster/isoqlog/bin/cron.sh

Commands that can be used:

qmailctl stat
/home/vpopmail/bin/vadddomain domain.com password
/home/vpopmail/bin/vadduser user@domain.com password
/home/vpopmail/bin/vmoddomlimits -S domain.com // view domain limits
/home/vpopmail/bin/vpasswd // change pass
/home/vpopmail/bin/vmoduser // modify user stats

Run :

rpm -Uhv http://apt.sw.be/redhat/el5/en/i386/rpmforge/RPMS/rpmforge-release-0.3.6-1.el5.rf.i386.rpm
yum -y install ffmpeg ffmpeg-devel mplayer mencoder flvtool2
cd /usr/src
Download http://garr.dl.sourceforge.net/sourceforge/ffmpeg-php/ffmpeg-php-0.6.0.tbz2
tar jxvf ffmpeg-php-0.6.0.tbz2
cd ffmpeg-php-0.6.0
phpize
./configure
make
make install

Edit /etc/php.ini and add :

extension=ffmpeg.so

and then:

service httpd restart
