Question : How can IPv6 be interpreted as IPv4?

Hi,

I was wondering how difficult it is to interpret IPv6 as IPv4.  If I send an email from a mail server that has an IPv6 address, how difficult would it be to deliver to a more traditional box with an IPv4 address?

can this be done, and how difficult would it be to do this?

Not that I am aware of.  There is no correlation between IPV6 addresses and IPV4 addresses so there is no way to deliver a message with an IPV6 address to a machine with only an IPV4 address.
