[imp] IMP and Virtual Named Host

[Brian]

hello List,

I'm new in IMP and I have one problem. I install Horde and IMP on my Server.

when I call the horde/index.php I get a Error

Not Found

 The requested URL /horde/imp/login.php was not found on this server.

The /horde/index.php are found because I see on the botten the Icons
"Horde", "Mail" and "log out"

in my errorlog of the Apache I see, the Server try to found the
/horde/imp/login.php in the default host of the apache. But the file is in a
Virtual named host default directory..

can someone help?

regards, Brian
