I get 1 or 2 mail failure messages a day form email@example.com that show up in my spam folder. I use att/yahoo webmail that was originally @sbcglobal.net, but when I dropped att DSL, they let me keep my email account. Am I correct that if an email I send is undelivered, that the notice I receive should be from firstname.lastname@example.org or email@example.com? And am I correct in assuming that the messages from kundenserver.de are spam and are a phishing expedition? Am I correct that my email server is either att or yahoo?
