Error in milter when trying to use relaydelay.pl

I am trying to get greylisting working for the first time.

Relaydelay.pl seems to startup correctly.  It sits there waiting for
sendmail to call it.  When I configure sendmail to use relaydelay.pl I
get errors in the sendmail milter.

This is the trace and error message:

--- SIGSTOP (Stopped (signal)) @ 0 (0) ---
--- SIGSTOP (Stopped (signal)) @ 0 (0) ---
--- SIGSTOP (Stopped (signal)) @ 0 (0) ---
select(5, [4], NULL, [4], {7210, 0})                                  =
1 (in [4
], left {7210, 0})
read(4, "\0\0\0\rO", 5) = 5
select(5, [4], NULL, [4], {7210, 0})     = 1 (in [4], left {7210, 0})
read(4, "\0\0\0\2\0\0\0\37\0\0\0\177", 12) = 12
time([1139004606])         = 1139004606
send(5, "<11>Feb  3 16:10:06 perl: relaydelay: st_optionneg[79125424]:

 not fulfill action requirements 0x3f", 108, MSG_NOSIGNAL) = 108
close(4)                                = 0
_exit(0)    

This is my configuration:

Redhat Enterprise 3	2.4.21-37.Elsmp kernel
Sendmail 		8.12.11
Relaydelay.pl		0.05 (pre-release)
perl-Sendmail-Milter-0.18-7.rhel3.i386.rpm

Question - is this configuration correct?  If so what does the error
message indicate? 

If this problem has been discussed before would you point me to that
discussion.

Thank you.
