This is a very broad question, so giving a specific answer is difficult to say the least, but since no one else has responded I will provide at least this much....
You are going to want to be looking at using a "hash of hashes" essentially you create a hash where each key is the email address (which you will be looking up on) and the value associated with that key is itself a hash. Here is one place to start: http://www.wdvl.com/Authoring/Languages/Perl/PerlfortheWeb/hash_of_hashes.html Or there are examples of these types of structures in the Camel, Advanced Perl Programming, and possibly the other perl related O'Reilly books.
