Do you think the mail that I received from this address is a spam ?

100% scam.

While there is a USAFIS green card diversity (DV) lottery, that email did NOT come from the US government.

The US government uses "dot gov" email addresses NOT "usa.com", NOT "yahoo.com" or anything else. The US government notifies winners via the United States postal service by sending paperwork to their home address NEVER via email. The next email will be from another of the scammer's fake names and free email addresses pretending to be the "diversity lottery official" and will contain a list of made-up fees to be paid in cash, and only by Western Union or moneygram.

Western Union and moneygram do not verify anything on the form the sender fills out, not the name, not the street address, not the country, not even the gender of the receiver, it all means absolutely nothing. The clerk will not bother to check ID and will simply hand off your cash to whomever walks in the door with the MTCN# and question/answer. Neither company will tell the sender who picked up the cash, at what store location or even in what country your money walked out the door. Neither company has any kind of refund policy, money sent is money gone forever.

Now that you have responded to a scammer, you are on his 'potential sucker' list, he will try again to separate you from your cash. He will send you more emails from his other free email addresses using another of his fake names with all kinds of stories of great jobs, lottery winnings, millions in the bank and desperate, lonely, sexy singles. He will sell your email address to all his scamming buddies who will also send you dozens of fake emails all with the exact same goal, you sending them your cash via Western Union or moneygram.

Do you know how to check the header of a received email? If not, you could google for information. Being able to read the header to determine the geographic location an email originated from will help you weed out the most obvious scams and scammers. Then delete and block that scammer. Don't bother to tell him that you know he is a scammer, it isn't worth your effort. He has one job in life, convincing victims to send him their hard-earned cash.

Whenever suspicious or just plain curious, google everything, website addresses, names used, companies mentioned, phone numbers given, all email addresses, even sentences from the emails as you might be unpleasantly surprised at what you find already posted online. You can also post/ask here and every scam-warner-anti-fraud-busting site you can find before taking a chance and losing money to a scammer.

If you google "fake green card lottery", "fraud diversity DV lottery scam", green card Western Union scam" or something similar you will find hundreds of posts of victims and near-victims of this type of scam.

Be wise. Any E-Mail that asks you for money is a SCAM! The infallible giveaway is the words "you won" when you didn't enter. Put that in your Scam Folder for later reporting to the proper authorities, should you choose. BIG SCAM!

Of course, it is a scam, Florina! Stop opening them! Opening spam mail tells the spammer that your address is a valid one and they send you loads and loads more!

Yes. Slice it up with a little cheese. Put on English muffins and bake for 20 minutes.

Of course it is spam. Anyone you don't know who asks you to send them is a spammer.

Never open emails from people you don't know ~ and do not send any money to them ~ it will be a con ~

Yep, looks like spam to me. I wouldn't open it.

FAKE! don't send any money to people you don't know!

Yep,

delete it, never respond to it...
