Study on understanding email configuration quality

[Tobias Fiebig <T.Fiebig () tudelft nl>]

Dear all,
I am a researcher at TU Delft in the Netherlands, looking into Security & Protocol Adoption.
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:

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. :-)
