[imp] Login problem with IMP

[Gary Hayers]

Hiya Folks,

I'm having some difficulties with Horde 2.2.3 and IMP 3.2.1. All I'm looking
to do is a standard Install to act as a Webmail client on a pop3 server on
Redhat 7.3.  For some reason that I dont know (being a relative newbie to
the Linux and PHP world) I am having a hard time loggin in to IMP, with the
following error:

Notice: Undefined index: enabled in /var/www/html/box/horde/lib/Horde.php on
line 166

Warning: Cannot modify header information - headers already sent by (output
started at /var/www/html/box/horde/lib/Horde.php:166) in
/var/www/html/box/horde/imp/redirect.php on line 106

Notice: (null)(): Certificate failure for box.hayers.org: self signed
certificate:
/C=--/ST=SomeState/L=SomeCity/O=SomeOrganization/OU=SomeOrganizationalUnit/C
N=localhost.localdomain/Email=root at localhost.localdomain (errflg=2) in
Unknown on line 0

It suggests to me that it is looking for an Imap server and not my pop3
server. If anyone has an idea of how i can solve this it would be very
helpfull.
