postfix-policyd-spf-python always appends <UNKNOWN> as recepient address

[Vasya Pupkin]

Here's an example:

Feb 22 08:40:14 vps postfix/smtpd[28134]: NOQUEUE: reject: RCPT from unknown[92.255.197.74]: 550 5.7.23 <email address hidden>: Recipient address rejected: Message rejected due to: SPF fail - not authorized. Please see http://www.openspf.net/Why?s=mfrom;<email address hidden>;ip=92.255.197.74;r=<UNKNOWN>; from=<email address hidden> to=<email address hidden> proto=ESMTP helo=<92x255x197x74.static-business.kzn.ertelecom.ru>

Correct version would be:

Feb 22 08:40:14 vps postfix/smtpd[28134]: NOQUEUE: reject: RCPT from unknown[92.255.197.74]: 550 5.7.23 <email address hidden>: Recipient address rejected: Message rejected due to: SPF fail - not authorized. Please see http://www.openspf.net/Why?s=mfrom;<email address hidden>;ip=92.255.197.74;<email address hidden>; from=<email address hidden> to=<email address hidden> proto=ESMTP helo=<92x255x197x74.static-business.kzn.ertelecom.ru>

In Ubuntu 16.04 it works as intended, in Ubuntu 18.04 <UNKNOWN> is always appended instead of recipient address.

This is not a bug, but an intentional design change to, by default, better protect user privacy. See man 5 policyd-spf.conf for details. To restore the previous behaviour, add this to the policy server's configuration:

Hide_Receiver = No
