Sometimes, email can fail to work properly. Fortunately, every message comes with its own log, which details all the steps it has taken.
In Yahoo! Mail, these details are usually hidden. But if problems occur — if you get a message long after has been sent, for example — you can take a look at all the header lines of a message.
