 In February 2024 Google and Yahoo announced some changes for sending
 mails:
 https://support.google.com/a/answer/81126?hl=en
 https://senders.yahooinc.com/best-practices/

 For example, both are now requiring SPF ''or'' DKIM and you need valid
 forward and reverse DNS record for your sending IPs.

 This is the requirement for all senders (for bulk senders with more than
 5000 mails per day there are even stricter rules).

 So using a Gmail address within WordPress and not having a valid SPF could
 lead to mails getting bounced for not passing the SPF check. Important
 mails (Password reset, fatal error handler, etc.) are not getting
 attention.

 Unfortunately, there is no easy way to check these settings. You need to
 know where you can set this up at your hoster or you need to know external
 tools for checking, like: https://mxtoolbox.com/SuperTool.aspx,
 https://www.nslookup.io or https://dnschecker.org/all-dns-records-of-
 domain.php

 So why not adding a DNS section to the Site Health report, adding those
 records? And some status checks where possible?

 As @swissspidy has pointed out on X/Twitter, this needs more thoughts and
 polishing before getting in core, so I have built a proof of concept as a
 plugin:

 This could easily be transformed to a patch for the Site Health component
 by me.

 I am interested in feedback and what should be changed to get this in
 core. Here or on GitHub.

 Thanks in advance!
