[Dovecot] Dovecot or postfix Quota

Yes, that could be doable. Although, dovecot's LDA doesn't actually
support this. And then there's the issue of race conditions: You ask it,
accept the mail, and when you go to deliver it the user has saved gotten
another mail in the meantime. At that point, you probably should just
accept it anyway, but if the LDA checks the quota again you'll end up
with a bounce message...

Sorry, I know nothing about postfix at all. And even for exim (which I
use) I couldn't tell you off-hand, but it's most likely possible to do.
