PMUG members already know to be cautious and careful with email. This morning’s example just came from commspeed.net and in the list of today’s mail it looked official. With asterisks setting off capital letters of IMPORTANT, the title said "Upgrade Notification."
Without opening the suspicious thing I went to Safari and then to commspeed.net. Here in the long list of mail I could click to view it without opening it on my computer. Misspelled words and poor use of English was another warning (“canceling insolent accounts” and “all data’s will be loss”).
Going to View Full Header revealed the spammers info. I did a Grab (screen shot) of this page and the email letter screen, copied both to an email which I sent to spam.commspeed.net with my own notation, “Go after these bums!”
