It is related to this issue. The user reports here that it is related to a change of hostname.

Check your /etc/hosts file and make sure you have an entry pointing to your hostname.

It would seem that the Sudo program or whatever it is sent this message as an alert that there was an invalid password attempt while trying to use sudo.

When I run sudo visudo, there is a setting Defaults mail_badpass that I assume is the source of this.

Further evidence that this is from the sudo program / whatever it is called: https://groups.google.com/g/rcdevs-technical/c/oUzjW0MZs_8?pli=1

echo 'Defaults !mail_badpass' | sudo tee /etc/sudoers.d/disable_mail_badpass
