port forward question

["Robert E. Martin" <rmartin () fishburne org>]

I have a web server inside a port fw box. This is a NAT box that runs 
iptables to allow port forwarding to a web server. I want to run a form 
script on the web server....formmail.cgi. The web server is a linux box 
with sendmail. Should I have port 25 open to the world to allow this 
form to work? I am kind of new to this so be gentle.

I suppose the real question here is , How do I allow sendmail to _send_ 
_mail_ from a dnat'd web server?
