This is what i get when i go to my webmail
Some of IMP's configuration files are missing or unreadable
conf.php
This is the main IMP configuration file. It contains paths and options for the IMP scripts. You need to login as an administrator and create the file with the web frontend under "Administration => Setup".
mime_drivers.php
This file controls local MIME drivers for IMP, specifically what kinds of files are viewable and/or downloadable.
prefs.php
This file controls the default preferences for IMP, and also controls which preferences users can alter.
servers.php
This file controls the default settings for IMP, and also defines the list of available servers if you are using the server list.
Create these files from their .dist versions in /home/httpd/html/horde/imp/config and change them according to your needs.
