What is the best way to determine if an email message warning is a hoax?

from spam experience, spam emails always start with dear sir/madam your bank or someone you are known to, know your name is not sir/madam also they normally have links directly from that email asking for personal info. NEVER give personal info through a link from emails even if you think there not spam. contact the correct site where the supposed email come from online and they normally have a address where you can send your suspicious email. they are hot on this topic now so you should get a reply pretty quick.
