Since I now get over 5500 spams per day, I use very vigorous filters and retire temporary addresses quickly. From some locations it is no longer possible to send mail here. Sorry but it has become a serious drain on resources. The tell me mail links at the end of each page will work if you keep the Subject line intact.
