    for line in f:
        names.append(line.rstrip("\n")

myEmails=set(names)

with open(outputfile) as fd, open("emails.txt", "w") as output:
    for line in fd:
        for name in names:
            c=line.rstrip("\n")
            if name in myEmails:
                print name #for console
                output.write(name) #for writing to file
