Morally, if neither you nor the person to whom you plan to pass the information will benefit directly then breaking the rules seems ok to me. However...
Before you gather together this list of email addresses you should probably decide EXACTLY what you plan to do with it. For instance, will you destroy it after sending out a single email, or after a certain period of time, or simply remove entries on request. Since you are on shaky ground, being absolutely clear as to your exact purpose may be helpful.
