If you want an IMAP specific method (rather than doveadm), you are 
stuck with "FETCH 1:* (RFC822.SIZE)".  With the nasty requirement - if 
you want 100% full accuracy - that you need to track responses to ensure 
that each size is only counted once.  Practically speaking this 
shouldn't happen by any reasonable server, but the warning needs to be made.
