That's because the stream switches to compressed mode right after
the "Content-Type" line.  It works on my home machine, but that's
with later changes to the accept string.  I see this in the trace
(indented for clarity):

while on this host (which doesn't work) I have (and since your tcpdump
shows a "compress" also, expect that it's comparable):

        GET / HTTP/1.0
        Host: mobil.t-online.de

"compress" is supposed to be handled by an external program, while
the others all have built-in support.  I didn't have "compress"
installed on my home machine, but see that there is a "ncompress"
package, and after installing that and building a copy of lynx, it
doesn't work with the site.

I'll investigate and see if the problem is a bug in lynx (which
can be repaired).
