Domain-based Message Authentication, Reporting and Conformance (DMARC) is an email authentication protocol. It is designed to give email domain owners the ability to protect their domain from unauthorized use, commonly known as email spoofing .
Instead, mailing list software was changed. [48] [irrelevant citation] In 2017, another working group was launched, DKIM Crypto Update (dcrup), with the specific restriction to review signing techniques. [49] RFC 8301 was issued in January 2018. It bans SHA-1 and updates key sizes (from 512-2048 to 1024-4096). [50] RFC 8463 was issued in ...
However, a strict DMARC policy may block legitimate emails sent through a mailing list or forwarder, as the DKIM signature will be invalidated if the message is modified, such as by adding a subject tag or footer, and the SPF check will either fail (if the forwarder didn't change the bounce address) or be aligned with the mailing list domain ...

The characteristic payload information of an MX record [1] is a preference value (above labelled "Priority"), and the domain name of a mailserver ("Host" above).. The priority field identifies which mailserver should be preferred - in this case the values are both 10, so mail would be expected to flow evenly to both onemail.example.com and twomail.example.com - a common configuration.
