I think you're attacking this from the wrong angle. Whether these cameras are on a private RFC 1918 network or a public broadband network, you should be able to accomplish your goals without need of SMTP emails. If broadband you must have a DSL/cable modem/router in front of the camera with public IP on the provider side and private IP on the inside. Use dynamic DNS on the public interface to get name<->IP resolution of the modem/router. On the router, configure the DHCP server to only assign one IP address, or a range that starts and ends with the same address. Create a NAT rule for the camera IP/port. From then on access the camera by fqdn, not IP. If this is a totally private network you can assign sticky static addresses in your DHCP server so that each IP camera always receives the same address on lease renewal.
