My mail server has been blacklisted on rfc-clueless.org RFC-Clueless DNS Real-time List The reason given by them is:

Domain shares an MX record (my.domain) for a mail exchange which is known to not handle null-addresses.

How can I solve this issue?

Hello @amstel,

Can you verify if you are using the default MX record for the domain name, and that the domain name utilized in the MX record properly resolves to an IP address? Or, are you using a custom MX record for use with a third-party mail server?

Thank you.
