The database at the NIC doesn't contain much "fine-level" detail on non-USA
hosts.  In fact, the only entry seems to be for 'PL-DOM', i.e., the top-level
domain for Poland.  There are no entries for 'EDU.PL' hosts, other than the
listed name-servers (FIZYK2.FUW.EDU.PL and COCOS.FUW.EDU.PL and
INFOSERV.II.UJ.EDU.PL) for this domain.

Sounds like the user ID at that node is no longer valid, i.e., nothing fancy!
The wording of the error-message is probably peculiar to the SunOS software.
Remove the ID from your mailing-list.
