Shortly later I was pleased to receive two nicely worked automated responses from Paypal:

Subject: RE: FW: Please review your billing agreement. ([pretentious number])

I would be more impressed by other Internet Services if they had similarly easy reporting and acknowledgment routines. I know my e-mails probably just went into counting routines but the feeling that they might go into an analytic engine for find distribution channels and/or origin made my morning.
I should perhaps add that I recently received a similar e-mails from two major security vendors asking me to click on links to join their advisory panels, alias complete marketing questionnaires. I forwarded them to contacts in the organisations concerned, because I could find no routines for checking whether they were was genuine, only to be told that they were !!!
