Hello Yuma and Anne, Anne's advice about rebuilding your mailbox if all else fails is a good suggestion, but prepared for this to take some time. Here's the relevant section about troubleshooting your mail from the "Take Control of Apple Mail in Leopard" guide (SL update not out yet):
<begin excerpt> Fix Mailbox Problems Most of the time, Mail works just as you expect it to, correctly displaying all the messages you’ve filed in any mailbox when you select that mailbox. If your mailboxes begin misbehaving, though— not displaying messages you know they contain or taking an extremely long time to show their contents, for example, you can try some easy tricks to fix them. If your envelope index—a special database that Mail uses to keep track of which messages are in which mailboxes—and the other files that Mail uses to catalog messages become severely damaged, Mail may exhibit any of several symptoms, including: • Missing messages • Incorrect message counts, in which the number of unread mes- sages shown next to the mailbox name in the sidebar differs from the number of unread messages you see inside the mailbox • An empty mailbox, even though you know it contains messages • Failure to move messages into a mailbox (manually or using rules • Incorrect or missing results when searching by message headers (From, To, or Subject) If you suspect that a mailbox contains errors, the standard cure-all is to rebuild it. To do this, select the mailbox (or more than one) and choose Mailbox > Rebuild. If that doesn’t solve the problem, quit Mail, navigate to ~/Library/ Mail and drag the file Envelope Index to the Trash. When you launch Mail again, it’ll tell you that you need to “reimport” all your messages (just as it may have done when you upgraded from Tiger to Leopard). Let it do so—it’s recreating your envelope index from scratch, but don’t worry, you won’t lose any data, such as labels or message status— and when it finishes, your mailboxes should behave correctly. <end excerpt> You'll see that your problems are included in the list of symptoms that rebuilding may fix.
