Hello Dave! (What are you doing Dave? - 2001 Joke :-) ) I'm not certain about this, but it seems possible that your cable modem provider could be blocking port 25 to external IPs. I know that my cable ISP would be none too chuffed if they found me running an SMTP server, but your situation could be different. If you can't find any other problems, then contact their technical support department to ask if this is the case. Just don't expect them to know what FreeBSD is when you call! :-) Also, even if the aren't blocking port 25, they may not like you running a server on it anyway; that is the situation I have with my cable ISP. So asking them about it may tip them off that you are trying to do it! Just a thought... Andrew.
