That's really discouraged these days, because spammers send a _lot_ of
mail to essentially randomly-generated addresses in the hope that
something will actually get delivered to a person with a wallet, and
if you have a catch-all rather than rejecting invalid recipients, you
actually _get_ all that spam (as you've seen).
Disabling your catch-all would cure 90%-ish of this problem. How
critical is that catch-all to you?
Unfortunately, fairly critical. I made the decision to use a catch-all
back in ~1998 (when, I'm sure, you'll tell me it was still a bad idea)
:)
Email addresses that are actually used conform, typically, to a fairly
constrained set of regexps (but not a constrained list of valid
addresses...)
Ah. Let me throw another idea your way, then: milter-regex. It would allow
you to validate recipient addresses against those regexes and reject at
SMTP-time if they don't match. Then the catch-all would only apply to the
ones that match the regex but aren't at the moment actual mailboxes. Would
reducing the inbound volume that way be acceptable?
At the moment, my only niggle is that when I receive a spam to multiple
addresses at my domain, this (identified spam) is still delivered
multiple times - even when the multiple addresses all resolve to the
same local account.
I have another data point that may help you figure that out. When you sent
this reply, I assume you sent it to the list and me, either both as TO
addresses or one as a CC address. I received two separate messages with no
mention of the other recipient. It seems postfix on ingwaz is splitting
one message into multiples on outbound as well.
It still seems odd, to me, that the envelope address can't necessarily
influence the spamassassin score... The envelope address, I suspect, is
more relevant than any other address found in the headers.
It certainly can if the MTA puts the envelope TO address into the headers
and if there's a rule looking for it.

entire nature of the social contract is changed. Each man’s worth
is measured solely by his utility to the state, and as such the
value of his life rides a roller coaster not unlike the stock
market: dependent not only upon the preferences of the party in
power but upon the whims of its political leaders and the
permanent bureaucratic class. -- Mike McDaniel
