SOLVED Missing mailboxes

[knollfinder]

Today, when I woke my iMac form sleep, I found that all of my mailboxes had disappeared, not the standard system boxes (inbox, sent, etc). I can't find any help in the help links.

You need to move your mouse over your account name, then you will see a >. Click on the > to expand and show your mailboxes.
