From the measurements, we are storing per-email provider aggregated statistics on the measured outbound mailserver configuration. This includes use of email security technologies, IPv4 and IPv6 support, and whether the provider validates DNSSEC. We store this data for the purpose of ongoing scientific research into the adoption of email security measures. If you are your own provider, this information might personally identify you, and we ask you to consider this before participating. If you did participate in the study and would like to have your data deleted, please write to firstname.lastname@example.org
, and we will delete your data as soon as possible.
If you opt-out from this service, we store a hash of your email address indefinately, to block-list your address.
