delay Sendmail start to after network settings loaded from DHCP.

not sure if there is any 'documentation correct' way of doing that but
'home crafted' one would be to move /etc/rc.sendmail to
/usr/local/etc/rc.d/blah.sendmail.sh and remove it from rc.config

hope someone here knows more proper way and can advise.
