Alert. Beware of emails from known legitimate sources that look authentic but are not. Below is an example received today. The image shown is a bit fuzzy, but the original is crisp and high quality. The best way to identify the authenticity of emails and their internal links is to hover your mouse over a link and see what address is revealed.
