I would first inspect the file(s) found at the following UNIX path(s):
/Users/<username>/Library/Mail/<e-mail account name>/<mailbox name>.mbox/mbox

If you want to use the Finder to do this (as opposed to the command
line), go to the Finder and choose "Go to Folder..." from the "Go"
menu. Then, enter /Users/<username/Library/Mail
When you see the 'mailbox' icons for folders ending in ".mbox", use
Control-click to get a contextual menu and then choose 'Show Package
Contents'. Next, switch to list view so you can see size of the mbox
file. Mbox files are plain text and contain all messages in sequential
order. (Note: the mbox files may be very large if there are many
e-mails.) I would check to see if all the messages are still there.
