Common Elements:
1. The email or requestor asks for bank account information, credit card
  numbers, driver's license numbers, passport numbers, your mother's
maiden name or other personal information. (Automatic Red Flag!)
2. The prize promoters ask for a fee (for administration, "processing", taxes,
  etc.) to be paid in advance. A legitimate lottery simply deducts that from
  the winnings!
3. Reply addresses to these scams are usually either to a or or any other public email provider, scammers like to use these free
  services. Remember if some huge financial institution or legal firm wants you
  to contact them, they would have a private domain with their own email
4. Most of letters received are written by people who have a poor command of
  the English language with errors in punctuation, grammar and over use of
  ellipses (periods, asterisks, dashes, etc.)
5. When selling an item online, someone offers you more than your asking
  price, usually to cover the so called shipping costs and they want the item
  shipped to a different location or another country.
6. The caller or emailer is a victim and was enticed to travel to, or moved to
  Nigeria or a border to country and now needs your help to return to the United
  States. Often times offering to send "over invoiced contract" funds to you or
  deposit them into your personal bank account.
7. The confidential nature of the transaction is emphasized.
If you have received any scams by mail, turn it over to your local Postmaster.
Lottery Scams
  You've been notified that you won an International Lottery and could receive a check for $400,000(or a similar amount). All you have to do is pay the tax or administrative fee.
  Key Points
  First, its a violation of US Federal Law to play an International Lottery.
  You never have to pay to collect winnings from a legitimate lottery. You pay taxes AFTER you receive the winnings. There are no other fees.
  If you hold a winning lottery ticket, you notify the lottery (they do not notify you; not by email, not by phone, and not by mail).
According to the Federal Trade Commission, Ignore all mail and phone solicitations for foreign lottery promotions. If you receive what looks like lottery material from a foreign country, give it to your local postmaster.
