88761 IMAP Sent Items Extract

I don't know what you would do this in it may just be playing with the server but I need all the sent items (email addresses) extracted from one of 1 domains. I don't know how to do this because I have tried with programs and it's not extracting anything... You will give me the address's in a text file with all dupes removed and i know what should be on there so no fake emails. Thanks...
