relay problem again

OK, what am I doing wrong?

1996-12-16 12:47:06 refused relay (host) to ctaylor@??? from <karen.elmore@???> H=smtpgw.cws.comsat.com [134.133.176.130]

configure says:

sender_host_accept_relay = *.comsat.com
sender_address_relay = *comsat.com

That's all it says in configure regarding relay.

Since smtpgw.cws.comsat.com should match sender_host_accept_relay, why
is it rejected?

BTW, a test program (that allowed me to pretend to be whatever sender
I like) would be handy. I know I can use telnet, but that's tedious.
