That's a desirable feature, but how to implement it?

You see an outgoing mail (IP 192.0.2.1, from toto@...,
titi@...) which matches the whitelist. You'd like to whitelist
answers of this e-mail. What tuple should be whitelisted? You don't have
the remote IP address yet.

We can whitelist (IP /.*/, from titi@..., to toto@...),
but that leave a door open for spam.
