a great first reply for you
probably the most popular free resource is fanmail.biz
personally I love startiger because it allows you to keep track of your requests as well and tends to have information updated more regulary but they do charge to use it, around £5 per month I think I pay
other than those, a lot can be found simply with google searches
If there is anybody specific you are looking for an address for, I am always happy to help where I can
I look forward to seeing your repluies atart rolling in
