My student Olamide is looking into how well email setups are maintained around the globe. For this, we need many people, ideally from smaller providers, i.e., with non gmail/hotmail/yahoo addresses, to send us emails. Please consider participating in this study, and sharing it in your networks. To help us, please follow the instructions at: https://www.email-security-scans.org/ Important caveat: If your mailer validates recipient addresses before accepting mails, you might be unable to send to destination addresses that are (a) only resolvable via IPv6 only, or (b) Have broken DNSSEC, which we use to test DNSSEC validation. If this is the case, please just remove the 1-3 offending addresses from the To: header. Please also note that our test setups will test whether the host delivering mails to us is an open relay. Also note that you may receive bounces from your mailserver for some of the destination addresses, e.g., if mails can not be delivered via IPv6, or if your mail-setup validates DANE records for our DANE test domain. We do _not_ need a copy of those bounces. In case you want to get results for a domain you operate or use early, please just drop me an email from the same domain and delivering servers after you participated, and I will share the data with you. :-) Met vriendelijke groet, Dr.-Ing.
