Quote from <http://www.postfix.org/SMTPD_POLICY_README.html>: The Postfix policy delegation protocol is really simple. The client request is a sequence of name=value attributes separated by newline, and is terminated by an empty line. The server reply is one name=value attribute and it, too, is terminated by an empty line. Here is an example of all the attributes that the Postfix SMTP server sends in a delegated SMTPD access policy request: Postfix version 2.1 and later: request=smtpd_access_policy protocol_state=RCPT protocol_name=SMTP helo_name=some.domain.tld queue_id=8045F2AB23 sender=...@bar.tld recipient=...@foo.tld recipient_count=0 client_address=1.2.3.4 client_name=another.domain.tld reverse_client_name=another.domain.tld instance=123.456.7 Postfix version 2.2 and later: sasl_method=plain sasl_username=you sasl_sender= size=12345 ccert_subject=solaris9.porcupine.org ccert_issuer=Wietse+20Venema ccert_fingerprint=C2:9D:F4:87:71:73:73:D9:18:E7:C2:F3:C1:DA:6E:04 Postfix version 2.3 and later: encryption_protocol=TLSv1/SSLv3 encryption_cipher=DHE-RSA-AES256-SHA encryption_keysize=256 etrn_domain= Postfix version 2.5 and later: stress= [empty line] p...@rick -- state of mind Digitale Kommunikation http://www.state-of-mind.de Franziskanerstraße 15 Telefon +49 89 3090 4664 81669 München Telefax +49 89 3090 4666 Amtsgericht München Partnerschaftsregister PR 563
