Hi, I'm Sam and have been lurking here for quite a while. I wanted to
chime in on this topic. Any effort expended on notifying the bulk
mailers as to the validity of an account at message accept isn't really
going to net any benefit. Bulk mailers spend more time farming new
addresses than maintaining their list of old addresses.
If you are trying to reduce load, you might consider just blocking the
offending MTAs with an RBL like solution, or at the firewall. For
example, I have pretty much all of asia and brazil blocked from one of
my servers. Kind of sad really, but so goes it.
The gain isn't in telling the _spammers_ they aren't welcome, the gain
is in telling _legitimate_ users whose mail was incorrectly rejected that the
mail _did_ bounce, and is not languishing in the spam-bucket waiting
to be deleted unread.
That's the gain- it makes a false rejection far less horrible a fate
than it would otherwise be.
