If you want to send outgoing mail directly you should, at very least,
have a static address and really you should have a static address with
full-circle DNS,

e.g.:

$ dig  +short -x 8.8.178.116
mx2.freebsd.org.

$ dig +short  mx2.freebsd.org
8.8.178.116

The requires that the ISP either sets the rDNS for you or delegates
it to your DNS server.
