	I've done a quick hack with MH sources (on Sun --- client) to
	comment out all lockf()s and made it always success (i.e. a file
	seems to be never locked).  Now I'm afraid of collision of MH and
	sendmail...  Anyway, isn't there any other famous program which
	uses lockf()s?

	Today there's another problem; I don't have confidence that this
	is concerned with lockf() (or rpc.statd).  A mailing-list driver
	shell script is denyed to execute by sendmail because it is
	``unsafe'' (sendmail says the script is chmod-able while I don't
	think so).  The script is on a FreeBSD machine exported through
	NFS, and sendmail is executed on a Sun SPARC.  Anybody has idea?
	(please do not say I should discard the SPARC (-_^)  ).

	Hmmm... I could hack that...
