spamd & grey-listing innovation

[Ed White <ed_(_dot_)_white_(_at_)_libero_(_dot_)_it>]

Hi,

I've noticed that most spam that I receive is directed to old/nonexistent mail 
addresses. Sadly my mail server reply with an "error" message and so keep 
wasting precious bandwidth.

I think that adding a new file containing only valid addresses could be an 
useful innovation. The trick is that spamd would add the grey-listing triplet 
to its database only if the destination address is present in the upsaid file 
(/etc/spamd.addresses ?).

This will permit to save a lot of bandwidth and to remove some load from the 
mail server.

Who likes it ?
