Ok, understood.
In case the messages are originated from your own host, they can be
"injected" via a local protocal (using sendmail) or via TCP. Both ways
can be blocked with ACL rules.
First we need to setup an acl for non-SMTP messages
…
acl_smtp_rcpt = acl_check_rcpt
acl_not_smtp = acl_local
…
Now we create a "sub acl" to be reused later
# this returns true(!) if the sender domain is on the black list
is_blacklisted:
accept message = blacklisted for local reasons
sender_domains = …
And then reuse this in several places:
acl_local:
deny acl = is_blacklisted
accept
acl_check_rcpt:
deny acl = is_blacklisted
…
But of course you should think about some rules to allow messages *from*
the bad domain to your postmaster! They need a chance to complain! :)
