can't login (pop3) - timeout

[Joel Gautschi]

hi,
I've just installed horde/imp... after installation I tried to login. but
after i pressed the "Anmelden" (login) button... it does nothing... till it
timeouts. (The page cannot be displayed/Cannot find server or DNS Error -
address is then: MYSERVER.Org/horde/imp/mailbox.php3

what's wrong?

thanks for an answer!!!
Joel
