In that scenario, unless Customer A was searching for >"joesmith" with a matching zip code, nothing would get sent.

Customer A knows his login name (joe) but not his password, and puts "joe" in the field for password recovery with his correct zip code. Since he (joe) has no Override E-mail address or E-mail addresses, OG is assuming that "joe@domain.com" is him and it sends that password there, but in reality "joe@domain.com" belongs to Customer B. --Mike --------------------------------------------------- To subscribe, unsubscribe or to search list archive please visit http://www.optigold.com/lists/isp.html ---------------------------------------------------
