that looks like a named syslog message to me....
here's another view:
$ host -C sgsp.edu.pl
sgsp.edu.pl NS ns.sgsp.edu.pl
ns.sgsp.edu.pl administrator.sgsp.edu.pl (33 900 600 86400 3600)
!!! sgsp.edu.pl SOA expire is less than 1 week (1 day)
sgsp.edu.pl NS arwena.nask.waw.pl
ns.sgsp.edu.pl administrator.sgsp.edu.pl (33 900 600 86400 3600)
*** sgsp.edu.pl SOA record at arwena.nask.waw.pl is not authoritative
sgsp.edu.pl has lame delegation to arwena.nask.waw.pl
That's from host version 991529 from ftp://ftp.nikhef.nl/pub/network/host.tar.Z

Any delegation of a zone to a server that is not authoritative for that
zone -- i.e. an NS record that points to a server which doesn't
secondary the zone.

I don't know what produced that, but:
$ host -t mx sgsp.edu.pl
sgsp.edu.pl MX 10 mail.sgsp.edu.pl
!!! sgsp.edu.pl MX host mail.sgsp.edu.pl is not canonical

The target name of an MX RR _MUST_ be a canonical hostname -- i.e. a
name that when resolved in the DNS returns an A RR.
(the same rule applies for NS RRs too)
