Email forwarding through a VPN

I have an exchange server on a private network connected by broadband to the Internet through a router by NAT. The router supports PPTP and IPSEC L2TP for Access Control and Port Forwarding. I wish to use email forwarding from the company providing me with a domain name and was wondering whether it would be possible to use a public static ip address as a "virtual email server" which would route all email through a VPN from the public static ip address to the physical server which resides on the private network. In turn I would like all emails originating on the physical email server to be routed through the VPN to the public static ip and onto the Internet. Is this possible and what specificaly would I need to ask the domain name provider and email forwarder to provide for me?

--yes, it is possible, you need to configure your router to NAT/port-forwarding that piblic static IP to your private, open port at least for SMTP (TCP 25) to allow inbound email coming in.

--yes, it's possible and again NAT will do the translation from private IP to public static IP.
Assume you already got a domain name and name servers for it, otherwise, register(buy) your domain first, for example networksolutions, many of them also provide DNS service. Next you need to put a MX record in your domain name servers and let it point to your public static IP address, and that's it.
oh, one more thing: you may ask your ISP to put a reverse DNS record for your public static IP address since more and more people on the Internet is checking email sender's identity.
