Mail Policy

Hello,

You've been referred to this page as a result of a mail delivery failure. Given you've actually followed the link in the bounce, here is some advice on what might have caused your failure.

  1. Your sender or recipient isn't valid for this server – senders and recipients must be fully-qualified.
  2. Your message must be plausibly reply-able – your domain must publish MX or A records.
  3. Your message must observe the sending domain's SPF, DKIM and DMARC policies. Generally speaking, having valid SPF and DKIM don't influence your score - but being non-compliant
  4. Your server configuration must comply with email best practices including valid forward and reverse DNS for both the sending IP and HELO (if different).
  5. Your sending IP must not be on common, high reputation IP blacklists.
  6. The content of your message must not be excessively "spammy" or malformed.
  7. You should not be sending potentially dangerous attachment formats.
  8. Your message should not have suspicious characters in the headers.
  9. Your message should not use MIME Type message/partial.

If you believe your message was rejected in error please open a support request. Please provide as much information (including the bounce message) as possible.
