  • sent from dialup IP range
  • sent from blacklisted IP range
  • invalid from: address domains
  • from: address valid, but delivered from a mail server
    not handling that domain (SPF or so on)

To resolve:

  • add DNS A and MX entries if on a static IP
  • add addresses to whilelist
  • deliver mail over smart host / other mail server

Kind regards,
