Greetings,
The Sender Policy Framework (SPF) is an easy way to check whether the sender is authorized to send emails – however, it may cause some security holes if it causes too many DNS lookups.
Together with researchers from Virginia Tech and Max-Planck-Institut für Informatik, we would like to understand which challenges operators face when configuring the proper limit of DNS queries for SPF lookups and when deploying other email security protocols.
Filling out the survey should take between 5 and 10 minutes; we would highly appreciate your participation.

Please note that we do NOT collect any personal information, thus the Institutional Review Board (IRB) at Virginia Tech determined the survey as Non-Human Subjects Research.
*We will aggregate and anonymize all responses during evaluation and share the results after evaluation. *
Please do not hesitate to drop me a mail if you have questions or comments.
