Trivial.

E:\>irb --prompt xmp
addresses = ["f...@bar1.com", "f...@bar2.com", "f...@bar3.com"]
    ==>["f...@bar1.com", "f...@bar2.com", "f...@bar3.com"]
competitors = ["bar.com", "bar1.com", "bar4.com"]
    ==>["bar.com", "bar1.com", "bar4.com"]
addresses.map{|x| x.split('@').last } & competitors
    ==>["bar1.com"]
