Puremessage for Unix 6.4.8 includes an upgrade for the built in Postfix to version 3.4.5
As a result of this the previous main.cf configuration option "ignore_policy_error" is now deprecated. Installs that are currently utilizing this will need to update their main.cf file with the new configuration options to prevent Postfix rejecting mail with the following errors:
Aug 22 12:22:43 hostname postfix/smtpd: warning: unknown smtpd restriction: "ignore_policy_error" Aug 22 12:22:43 hostname postfix/smtpd: NOQUEUE: reject: RCPT from server.domain[126.96.36.199]: 451 4.3.5 Server configuration error; from= to= proto=SMTP helo=
We understand this is far from ideal and are monitoring how many people are affected by this.
[Update]: This is now documented in the release notes for 6.4.8
