WKS query handling for CSV2 star entries

If I use
	csv2["*.ucmerced.edu."] = "star.ucmerced.edu.csv2"
I get an error for WKS queries to matching domains.
	$ host -t wks eecs.ucmerced.edu engdns00.ucmerced.edu
	eecs.ucmerced.edu WKS record query refused by engdns00.ucmerced.edu

	Nov 18 02:48:24 engdns00 maradns.etc_maradns_mararc: Query from: 207.42.123.4 Ueecs.ucmerced.edu.
	Nov 18 02:48:24 engdns00 maradns.etc_maradns_mararc:  Log: Bad query received: 9\027\001\000\000\001\000\000\000\000\000\000\004eecs\010ucmerced\003edu\000\000\013\000\001

If I add a record for just that domain
	csv2["eecs.ucmerced.edu."] = "star.ucmerced.edu.csv2"
it works as expected.
	$ host -t wks eecs.ucmerced.edu engdns00.ucmerced.edu
	eecs.ucmerced.edu has no WKS record at engdns00.ucmerced.edu (Authoritative answer)

It seems that sendmail uses WKS queries so mail to my domains from such
systems has been failing due to DNS timeouts(?!).
