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...
