No, this is not the problem. I searched in httpd.conf but I didn't
find anything concerning my <old_hostname>.
I even deinstalled & deleted the configuration files & reinstalled apache.
Don't forget this:
FreeBSD 5.4-PRERELEASE #10: Wed Mar 9 15:40:46 UTC 2005
<my_name>@<old_hostname>:/usr/obj/usr/src/sys/GAHR
Here I have my <old_hostname> too.

It should be so, but it actually isn't.

I'm sure I didn't set my <old_hostname> anywhere else than in rc.conf

However, thank you for your advice, but it didn't solve my problem...
