Tried something new.  Seeing index error messages from this new message:
Dec  1 10:53:13 bubba dovecot: imap(dmiller at amfes.com): Error: FETCH [] 
for mailbox Trash UID 17487 got too little data: 266965 vs 273669
Dec  1 10:53:13 bubba dovecot: imap(dmiller at amfes.com): Error: Corrupted 
index cache file 
/var/mail/amfes.com/dmiller/mdbox/mailboxes/Trash/dbox-Mails/dovecot.index.cache: 
Broken virtual size for mail UID 17487

Without obliterating the message, just shifting it between mailboxes 
(deleting from Inbox and moving to Trash) did nothing.  However, I then 
tried moving the message to a different account - and then brought it 
back.  This eliminated the index errors, and now yields:

larger than expected (247862)

Does this help you at all?
