André Stein a9c4bb3615 Adapted Postfix configuration to block typical spam sending ... mail servers using an enhanced client, sender and helo restriction configuration. The configuration has been adapted using this blog post: https://www.webstershome.co.uk/2014/04/07/postfix-blocking-spam-enters-server/ Basically mail servers having invalid configuration (as e.g. sending from and dynamic IP or a misconfigured hostname) will have their mails rejected. Additionnally three RBL servers are used to detect spam sending IPs: dnsbl.sorbs.net, zen.spamhaus.org and bl.spamcop.net. The results of a 12h test drive using a 100+ daily spam mail account (SpamAssasin was always enabled, just counting delivered mails to inbox not counting what SA detected): - Before: 34 incoming mails - Afer change: 6 incoming mails (82% reduction) Fixes #161.		2016-04-27 08:23:12 +02:00
