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.
