Hi all. I was getting email from my webservers email address, but it
wasn't really my webserver.

Made a restriction class that said only accept mail to this address if
and only if it is in fact from my webserver:

######################################
### SMTP Restriction CLASS Section ###
######################################
                                                                                        smtpd_restriction_classes = from_freemail_host, spam_haters, only_from_my_webserver
only_from_my_webserver = check_client_access
hash:/etc/postfix/my_webserver_hosts,
        reject Hmm. You look like my webserver but are Not.
...

and my_webserver_hosts contains:
host.mywebserver.tld OK
...

and in smtp_recipient_restrictions:
...
hash:/etc/postfix/recipient_access

and recipient_access contains:
address_frommywebserver.tld only_from_my_webserver
...

This works as expected except, I can't seem to issue the response I'd
like to give to those sending MTA's who have illegally harvested the
address. --"Hmm. You look like my webserver but are Not."

Hope this helps someone else.
Comments welcome.

Regards,
Eric
