Ah, that's a good point.  I've been using Postfix and Dovecot Local Delivery
Agent long enough that I'd forgotten about those folks who have their MTA drop
mail into /var/mail/%u etc which is then picked up by their imapd.  Dovecot
LDA receives from Postfix via pipe, so mail doesn't actually hit the disk
until Dovecot decides where it goes, via sieve scripts, for example.
