[Exim] Should I read the manual or ?

I have users that are really spammed ... I need to bounce messages that are
sent to those people ...

I use the "lsearch*" features ...

Is that possible to make "lsearch*" fail for a particular user ?

PS : I know that there is a way to do it with the smart_user feature, but I
don't have enough time to implement it yet :(
