So do it at SMTP RCPT time; you can control per user then, assuming the
blacklisted address is an envelope sender. e.g.:

MAIL FROM: <[EMAIL PROTECTED]>
  250 OK
RCPT TO: <[EMAIL PROTECTED]>
  550 Go away, blacklisted
RCPT TO: <[EMAIL PROTECTED]>
  250 OK

It's very easy to do this with Exim; I'm sure other MTA's/software
configurations must be able to do a similar thing.

Write a script to generate the SMTP-time access file periodically, from
individual user blacklists?
