I understand you sent an email to yourself?
If you gained one $message_size upon reception and lost 2*$message_size 
upon deletion from Inbox+Sent, I would suspect quota plugin isn't active 
when the message is being delivered. How are messages delivered? Dovecot 
LDA, LMTP or an external MTA?
You really should use LDA or LMTP to handle quota accounting.
