What is Scanmail.at?
Scanmail is part of my bachelorthesis on TU Vienna and it's main goal is how to infer IPv6 adresses only from IPv4 connections via DNS sidechannels in mail-based applications. The data we gather is only used for research purposes and we won't use it to do any harm or damage to tested systems. We don't like spam either but we need to send actual mails for our tests, but this is limited to a maximum of 2 mails per domain and you will not ever hear from us again. If you don't want your data to be evaluated you can opt-out here and you won't receive any further mail from us. If you have any questions you can contact me on email@example.com
