Its a bit of a fake test that one - the problem is not what the mail says sometimes but what it does - i.e. does it actully send you to the proper site etc. I.e. Does the link to
www.paypal.com actually take you there.
Also, if it says it will suspend you account its probably fake or if it is mis-spelt its probably fake as well.
If you get a mail and your unsure always manually enter the site into your browser and never click the link, assuming of course that you actually have an account with the people who claim to be sending you a mail.
