An nicer/cleaner solution would be to have a new setting in the LDAP
database and having that value checked when mail is delivered. People
could then choose between blacklists and greylisting and some header
checks for example.
I know this is doable with postfix; I've used some recipient specific
filters. I've heard some people say that exim could do that as well. If
indeed it is, we should definitly try this.
Sounds like something to do post-sarge when people have a little more
time on their hands.
