Probably because the server that was contacted was so hasty it
disconnected immediately:

telnet mx0.gmx.net 25

554-{mx028} Your address is listed as dynamic on SORBS (dul.dnsbl.sorbs.net)
554 We are currently not accepting connections from such hosts.

Connection to host lost.

And so Postfix tries again and again and again...
until max_queue_lifetime is reached. :((
