Installing FreeBSD without sendmail

[Joe Halpin]

Sorry if this shows up twice. My mailer keeps defaulting to the wrong 
email address and I don't always catch it.

Is it possible to install FreeBSD without sendmail? My machines are
behind a NAT firewall and don't have a domain name. Every time I install
I have to wait for sendmail to timeout looking for its domain name.

Wouldn't it be more secure to not have it enabled by default anyway?
