  • Spammed by a Hacker News Enthusiast
    This is what mailinabox does (https://mailinabox.email/) to combat spam and it has worked remarkably well. In the few years I've been running my own mail server I have received ZERO spam in my inbox. For more info, the technique is called greylisting https://postgrey.schweikert.ch/. - Source: Hacker News / over 1 year ago
  • Spam domains that plague my email
    I've used Postgrey, for Postfix, and it's greatly reduced my spam. However, first emails from new folk are delayed a bit. https://postgrey.schweikert.ch/. - Source: Hacker News / almost 2 years ago
