Sounds like this whole issue could have been solved by using as the
domain name something that only resolves internally, @localhost or
whatever.

Simplified, this expression could be rewritten:
/(not)?spam\@/ REJECT
but it still does not do what you want.

You put the .* in the wrong (useless) place rather than where you
needed it to be:
/(not)?spam.*\@/ REJECT
between the string and the '\@'.
I like to remind people of Zawinski's famous words about solving a
problem with regular expressions, thereby yielding two problems!
Perhaps you really wanted:
main.cf ::
recipient_delimiter = -
smtpd_recipient_restrictions = [ ... ] reject_unauth_destination
[ ... ]
check_recipient_access hash:/etc/postfix/dspam_check_aliases
check_sender_access hash:/etc/postfix/dspam_check_aliases
dspam_check_aliases ::
s...@example.com REJECT
nots...@example.com REJECT
Simpler, and this could be integrated with a general-purpose address
lookup, if desired.
