* | MX: Port to Debian 10. | Guilhem Moulin | 2020-05-16 | 1 |
| | | | | | | | | For postfix, don't defer if "abused legit". (I.e., DBL return code in the 127.0.1.100+ range.) This used to work for Postfix 3.1.14 (Stretch) but for 3.4.8 (Buster) the 'defer_if_reject' also applies to $smtpd_relay_restrictions, to reject_unauth_destination & reject_unlisted_recipient in particular. | |||
* | MX: Install OpenDMARC to add Authentication-Results headers. | Guilhem Moulin | 2020-05-16 | 1 |
On the infrastructure boundary. We don't reject/quarantine as it would affect members who forward their mail sent to <user@example.com> to <user@fripost.org>. Members can install Sieve rules to send any messages with failed Authentication-Results headers directly in their spambox. |
