IRS warns against e-mails scams

Today I released from "proofpoint" messages one that appeared to be from the IRS, and learned that I have a refund coming. It seemed suspicious, so I checked out the IRS official site, and learned they are again warning against e-mail scams. It is best to delete the message without opening it, according to the IRS. The IRS states it does not use email to initiate contact with taxpayers.
