Thanks, but we don't use that hostname for sending e-mail so the fact it does not exist has no relevance. If this is something that is interesting to you, you should really look up what MX records are and how they are used. |

Hi elwood, you actually use the host name while sending mail. When bugs.kali.org sends out external mail, the following IP sends the email: 208.88.127.98. The IP does EHLO with smtp.kali.org. Several mail servers (including mine) are configured to drop mails that are being send out with an non-existing DNS entry for the hostname in the EHLO message for spam blocking reasons. This results in the mails being dropped. You might want to consider adding a DNS name for this IP (and 23.239.31.82 which is also being allowed to send mails for kali.org according to your SPF record), or configure the mail server to identify as another existing hostname while sending emails to avoid your mails being dropped at some systems. |

Thanks for the report @constcast. |

This shouldn't be an issue any more since we are no longer self-hosting email |
