After installing the DKIM/DMARC filter that implements PSD, I can say that the impact is unnoticeable. I didn't carry out precise measurements, I just didn't notice any delay. Perhaps because I don't get so much mail from gov.uk, but I don't think I could reliably measure a positive delay even if I were a strict correspondent of Boris. > Rather, it's primed as a possibly useful data collection exercise. Kurt also talked about reporting some findings. I'm embarrassed, I have no idea what I, as a receiver, should report. What data should I, and other receivers collect? IMHO, the experiment should be conceived as having it run by as many receivers as possible, so as to have a noticeable effect on senders. They can collect aggregate reports and make a comparison.
