Convert Internet E-mail Addresses to Notes Addresses

I have a list of IBMer internet-style address that i would like to convert to Notes-style email addresses. Is there a way i can do that in Lotus Notes 8?

In Notes 7 I was able to do it by typing a comma after each internet-style address.

The reason I want to do this is that I want to:

  • eliminate duplicate recipients where I have both forms of their IBM email address

  • ensure the sent email retains notes features such as sections
