IMP login problem

[Damir Dezeljin]

Dear all,

I have problems with login in IMP mail system ... I have RH-7.1,
php4.0.4pl1-9, horde-1.2.4-1rh7, imp-2.2.4-1rh7 and mySQL.

When I try to login on the "login homepage" I get a listing of my mails,
but when I try to read one of them I get jumpet to the first ("login")
screen.

The problem is that my IMAP server logs me out imidiatly after login ...
some logs:
Jun 16 13:15:15 MyHost imapd[17828]: Authenticated user=dezo host=MyHost.MyDomain.si
    [127.0.0.1]
Jun 16 13:15:15 Ciril imapd[17828]: Logout user=dezo  host=MyHost.MyDomain.si
    [127.0.0.1]


Why it hapens??? Can someone help me???

I have the same instalation on the other server (some apache, php, imap,
RH-7.1, horde, imp) and there all is working fine ... what I have to
check???

Regards,
