There is no DKIM signature. It shows right away because of the little icon on the "From" line, displayed by my DKIMStatus plugin for roundcube.- The link below "To get start" (with a spelling mistake that I didn't notice at first) point to http://oncu*****.com/bura****.com.tr/index4.html, which is obviously not the BoA website...
Still, this phishing is one of the most dangerously well crafted I've seen in a long time... Stay sharp, and don't click on these links!
