Yes, that's true for tcpserver which just closes the connection when the client is blacklisted. However, using tcpsvd you can spawn a different program to handle connections from "blacklisted" clients, such as rblsmtpd with $RBLSMTPD set to "-Go away, spammer", which will result in a 551 error being sent to the client. Actually, if you place rblsmtpd in front of spamdyke in the delivery chain, you can also do this with tcpserver and spamdyke.
