you have lots of options here...

1. run two sendmails.. one binded to port 25 and the other one binded to 
above port 1024 (but i prefer to use port 80 because most firewalls allowed 
port 80 to pass thru)
2. run one sendmail that binded to port 25 and make a firewall rule to 
redirect or forward port 80 to port 25
3. using dial-up vpn
