[admin] Inconsistent DNS record?

[Edi Weitz]

I've received various bounces from common-lisp.net mailing lists today
which looked like this:

      host mx.freenet.de[195.4.92.211] said: 550 inconsistent or no
      DNS PTR record for 80.68.86.115 (see RFC 1912 2.1) (in reply to
      RCPT TO command)

Is there a problem with the c-l.net DNS setup?

Cheers,
Edi.
