It's also a solution, but this way the connections will be accepted by the tcpserver and a qmail-smtpd process will be started. I wouldn't do it this way.

if it is a massive spam, better filter it out with packet filter - 
iptables, ipchains pf etc, it depends from the OS you're using.

the fastest possible (the command is under linux) way to effective block 
is with route

route add -host 1.1.1.1 gw 127.0.0.1

the line in tcp.smtp (and rebuild with qmailctl cdb) also works, but is 
not as effective as packet filtering - if your server is having a 
considerable load just to deny the conenctions.

i've been in such trouble - there are guys which are trying to send to 
womehting like a wordlist of names, one connection per [EMAIL PROTECTED], 
and the server was about 3 times heavier load than usual - the guy(gal? 
gay?) was quite fast.
