Postfix IPv6 Defaults

According to Postfix mail list [1] Postfix RPM has IPv6 enabled by default.

Postfix source code distribution has IPv6 DISABLED by default for security reasons.

It could be better to disable IPv6 because IPv6 autoconf could break security.

  • You are telling the wrong people.

    CentOS is a bug for bug rebuild of RHEL. If it’s enabled in RHEL then it WILL be enabled in CentOS, regardless.

    If you have concerns then you need to file a bug with Red Hat for them to address it in RHEL. Any changes will then filter down to CentOS. That’s how it works :-)
