Tom,

You need to PAT or overload all of the inside addresses to the global IP.
You can do that with one of the following commands:

ip nat inside source list NAT_INSIDE interface Ethernet0/0 overload
(Preferred method if your router uses DHCP to get outside address)
ip nat inside source list NAT_INSIDE pool NAT_POOL overload (Points to a NAT
pool which contains only one address)

As far as allowing inbound traffic, you will need to do Port Redirection as
follows:

ip nat inside source static tcp 172.16.2.0 80 216.93.95.244 80 (Maps all
inbound HTTP traffic to the local address of 172.16.2.0)
ip nat inside source static tcp 172.16.2.1 25 216.93.95.244 25 (Maps all
inbound SMTP traffic to the local address of 172.16.2.1)

HTH,
