A few times I've had a mail message, which I can clearly see on my iPhone using a non-Apple mail reading app, state "This message has no content" in Mac Mail and I can't see it.
I can see another thread here that states one solution is to drag the mail to another mailbox and then back. This does not work for me, no matter how much I try.
Please fix this?

Safe Boot from the HD, (holding Shift key down at startup), does the problem occur in Safe Mode?
Safe mode attempts to repair Disks & clears lots of caches, so if Safe Mode works try again in regular boot.
If you have no POP accounts & they’re all IMAP accounts then in Mail’s Mailbox menu choose Rebuild.
