Hi - now after long search i know the login problem with IE. It is not possible to log in because the domain is registered by another registrar then the webspace. I changed the DNS (nameserver) of the domain to the webspace DNS, but that causes that login error with IE (Firefox works fine).

What can i do that it works also with IE?
This is what i have done:

mydomain.com (registered at X)
redirect to my server
(ns.server.com & ns2.server.com)
The Nameservers have 2 different IP-Addresses
(maybe thats the Problem - should i add only one Nameserver?)

there are the settings
*.mydomain.com (wildcard) Type A and
mydomain.com Type A
*.mydomain.com (wildcard) Type MX (priority 100)
mydomain.com Type MX (priority 100)

There i can select more types (A, AAAA, CNAME, MX, SPF or NS) - is this right what i have done?

And why this dont work with IE?

in my zone file for a root domain I've got:

* TTL(14400) IN CNAME mydomain.com.

and then the wildcard in the apache serveralias. So maybe try the CNAME rather than an A record. The different name servers shouldn't be a problem as that's the preferred way rather than having both on the same server.
