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. Additionally, you can ask us to store the emails you sent us for up to two weeks, so you can download them later.
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 iuse the delete button on the report to delete your data.
If you opt-out from this service, we store a hash of your email address indefinately, to block-list your address.
