SMTP error from remote mail server after initial connection:
host MX-4.rodents-montreal.org [98.124.61.89]:
550-.de's whois server, whois.denic.de, is completely broken, handing
550-out no contact information at all when queried for .de domains in
550 the usual way. Such a domain has no place on a civilized network.
This is just wrong. Of course they hand out contact information!
Sorry, I had to post it here since I cannot contact you directly.
No, Mouse is right, it's broken:
$ whois uni-stuttgart.de

$ whois -h whois.denic.de uni-stuttgart.de

So then I try this:
$ telnet whois.denic.de 43
Trying 81.91.170.6...
Connected to whois.denic.de.
Escape character is '^]'.

So far, so good. The server's alive (yes, I also tried the
"alive@whois" command). But:
$ telnet whois.denic.de 43
Trying 81.91.170.6...
Connected to whois.denic.de.
Escape character is '^]'.
whois -r uni-stuttgart.de
% Error: 55000000007 Request not clearly specified
Connection closed by foreign host.
$
That's broken.
And there is little helpful documentation about how to query the whois
service at the URL given in the HELP text. I eventually found a document at
https://www.denic.de/fileadmin/public/documentation/DENIC-12p_EN.pdf
which describes how to make a whois query of this rather idiosyncratic
server. It states that it should work as I tested it - but even
adopting the example given in that document fails:
$ whois -h whois.denic.de -T status uni-stuttgart.de
% Error: 55000000007 Request not clearly specified
$
$ telnet whois.denic.de 43
Trying 81.91.170.6...
Connected to whois.denic.de.
Escape character is '^]'.
whois -T status uni-stuttgart.de
% Error: 55000000007 Request not clearly specified
Connection closed by foreign host.

Epic fail.
