As a followup, we just had this happen again on an mbox POP3 check. Using 
pine, the message appears normally. I used telnet to access the POP box 
through dovecot, issued a "RETR" command on the new message, and it was 
blank. then I issued a "RETR" command on the email before it, and again a 
RETR command on the "blank" email and it appeared normally from that point 
forward using dovecot.

Hope this helps in figuring out this issue.
