As others have pointed out, this is how internet mail works. But I see
a perhaps unspoken assumption in your email that all email comes from a
particular relay machine? If so, either firewall port 25 to only allow
access from that machine, or (better) do that and add something like:
deny !hosts = : 127.0.0.1 : +relay_hosts : +inbound_relay
before any of the accepts. This can even go earlier than the rcpt time
checking if you like - acl_smtp_connect would be fine.
