Sophos – PMX 6.4.8 upgrade and ignore_policy_error option
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[188.8.131.52]: 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

What to do
- Check for the existence of this configuration option within your current configuration. This will be present in your Postfix /opt/pmx/postfix/etc/main.cf file and will look like the following:
smtpd_client_restrictions = ignore_policy_error,check_policy_service inet:[127.0.0.1]:4466
- If the ignore_policy_error option is not present then no action is necessary
- If however ignore_policy_error is present then that line will need replacing with the following 2 lines immediately after upgrading to 6.4.8:
smtpd_client_restrictions = check_policy_service inet:[127.0.0.1]:4466
smtpd_policy_service_default_action = DUNNO
