Thanks for this information.
I have added a deny which uses these variables to the acl_smtp_rcpt ACL
so that these type of e-mails coming from the internet via our company
relay to our local MTA are rejected:
deny sender_domains = +local_domains
hosts = +company_relays
message = From spoofed sender: '$sender_address'
coming from host: $sender_host_name [$sender_host_address] - discard!
Thanks
