1.You have to create the .ldif files, by using the Tools|Export function. This is a backup, as well as a way to import Addrress books.
2. the abook.mab file will contain the default address books, i.e. Personal and Collected. Any other address book which you create will be in files like abook-1.mab. and finally, if you imported a file, it will be impab.mab,etc. I have five different files in Netscape 7.2, three of which were imported.
So, there is more than one place to look, although I don't know if it will help you with the mailing lists.
But, keep in mind one thing. You are much safer by having address books separate from what is given to you. And, backup.
