You started your own topic by replying to the list mail with subject
"Installation gone wrong...".

There is an official mail system which controls guido-leisker.de as its
local domain and as well your home system with the same domain?

Is that a result from trying to send mail to the real guido-leisker.de
mail server?

If guido-leisker.de is treated as you local domain, then mail will not
be send for recipients of this domain to an external MTA.

$ echo '$=w' | /usr/lib/sendmail -bt

If guido-leisker.de does not appear there, then mail to this domain will
be sent to the responsible MX or A record host. Maybe you want to add
this domain to /etc/sysconfig/local-host-names.

I am not sure what you want to achieve. You give confusing information.
Please elaborate if the hints are not enough.
