I suspect that Netscape uses exactly the same profile folder setup as Mozilla, seeing as it is just a rebranded Mozilla now... Presumably they store emails in each profile folder. Look under:

C:\Documents and Settings\Username\Application Data\Mozilla\Netscape\Profiles

Or something to that effect. You should be able to just copy the entire Profiles folder from the old install to the new install, and get your browser restored to exactly the same state (it worked for FF on my laptop). I see no reason why Netscape would have bothered wasting development resources on altering the Profiles.
