I m very much confused that can one have the i.d example@google.com Becoz someone has made such an i.dandsending me stupid e- mails
yeah you can get Real one if you work for google but if you are getting spam then it's just one using some kind of script/programs to spam you and he isn't related to google check the message header anyways
i think that you can send from any bulk email sending software , there have one option for enter reply mail adress ,
im getting all this crap from a microsoft one saying i won $1,000,000 from some email address lottery. I sent them a abusive email because it was so obvious it was fake, who would give away $1,000,000 geez.
If you think it is a spam mail you can check wheter it is spam or not http://www.snopes.com/ But they do not have each and every spam mail on their database. But many popular spam mails are listed there. This one is one of the popular spam: http://www.snopes.com/inboxer/nothing/billgate.asp I don't know who and why they are doing that and what they are going to get?
