This was suggested to me but I have no idea how to implement with exim. Has anybody heard of this or know how to do it with both incoming and outgoing email?
"It is possible to run content-based filters inline, and in fact, that
is the only way with which you will not generate bounces to unrelated
third parties. With "inline", I mean that when the sender finishes DATA with a ".",
you run the filter, and don't return a SMTP response until the analysis
is complete, at which time you may return either a 2xx (to allow the
message to pass) or a 5xx (to indicate that the transmission has been
unsuccessful)."
