You get hundreds of mail every day and among them perhaps at most a couple of dozens of mail are worth taking note of and the rest are either promotional or some or the other newsletter for which you have every subscribed. But all of a sudden you get a mail that is very convincingly authentic yet you suspect its nature. Such mails are more often than not viruses in discguise send by hackers to infiltrate your account. The best solution would be not to open it and get in touch with the ethical hackers of the yahoo customer service and ask them to block the source from sending further mails to you.
