Interesting, and useful.
However,
deny condition = ${if match_domain{$sender_helo_name}{+local_domains}{yes}{no}}
message = Forged HELO: you are not $sender_helo_name
log_message = Forged HELO: $sender_helo_name is one of our \
local domains
Lumping in +local_domains into denials could cause problems - if your
outbound mailserver is a different machine, and people within the
company are Cc'ed, would that not trigger this ACL ?
