[imp] Imp Timesout when trying to contact mail server.

[Alan Hicks]

I've struggled for two weeks with this with no results.  I've installed
horde and imp on a RedHat 7.2 box as per the HOW-TO linked to on Imp's
webpage.  I have all the proper RPMs installed and working.  This machine
is an e-mail server (both POP3 and IMAP) as well as the webserver, so all
the neccessary programs are running.

Whenever I attempt to login by browsing to /horde/imp/login.php and enter
a valid username and password, the requests timesout.  All it puts in the
logs is:

192.168.1.80 - - [25/Apr/2002:11:03:00 -0400] "GET /horde/css.php?app=imp
