I forgot to mention that there are two Yahoo email addresses involved, the glenstrek address I use on list and info@[my business name].com which is a low end commercial domain name also hosted hosted by Yahoo. One strange thing is the 2 or 3 spams to the business email addresses are clients I have done no business with recently and have done little business with over the years. These are good folks, repeat customers that just do not need my services that often. In addition one these spams was found in the Yahoo spam folder. Next time this happens I will definitely check the full headers and report back if necessary. My concern is security. If some spammer has access to my address book and can send spam spoofed from friends and associates' email address what else do they know; SS numbers, CC numbers, bank accounts, passwords??? Dan and Doug, thanks for you help and I will definitely change many passwords. --glen -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
