Hello there,
my goal is to reject emails from domains that well-known use DKIM for
their outbound emails if signature is missing or invalid. But - because
I receive emails from many mailing lists - only if sender_domain is one
of these well-known senders.
Does this ACL do the job?
deny message = DKIM check failed
sender_domains = gmail.com:ebay.com:ebay.de:paypal.com
dkim_signers = gmail.com:ebay.com:ebay.de:paypal.com
dkim_verify_signers = $sender_address_domain
dkim_status = none:invalid:fail
Thanks & greetings,
Paul
