Passou de onde o nmap?

% netstat -p tcp -na
Active Internet connections (including servers)
Proto Recv-Q Send-Q  Local Address          Foreign Address        (state)

% nmap -p 25 192.168.1.100

Starting Nmap 4.20 ( http://insecure.org ) at 2007-01-19 21:10 BRST
Interesting ports on 192.168.1.100:

% nmap -p 25 127.0.0.1

Starting Nmap 4.20 ( http://insecure.org ) at 2007-01-19 21:10 BRST
Interesting ports on 127.0.0.1:
PORT   STATE SERVICE
25/tcp open  smtp

Nmap finished: 1 IP address (1 host up) scanned in 0.121 seconds


Detalhe: o nmap foi disparado na máquina que está com o sendmail rodando, ele
apenas está aceitando conexões na interface local (lo0 / 127.0.0.1).
