a) Use deliver -e parameter and configure your MTA to wait on replying
to DATA command until deliver has finished. I don't know how to make
Postfix do this (or perhaps it does it by default? dunno).

b) Use quota_warning scripts on 100% quota usage to update user's "quota
full" bit in a database (or wherever) and have Postfix reject RCPT TO
command based on that information. I don't know how to do that on
Postfix's side either.
