If you use the following sript all on one line it should work.  I also 
recieved some errors like you described until I put it all on one line.


 ( sleep 3 ; echo "HELO rainier" ; sleep 2 ; echo "MAIL FROM:
<you@foo.bar>" ; sleep 1 ; echo "RCPT TO: <you@foo.bar>";
sleep 1 ; echo "DATA" ; sleep 1 ; echo "Subject: subject here" ; echo ;
echo "." ; sleep 1 ; echo "QUIT" ) | telnet mail.host.somewhere 25
