Randy, Thanks for the concern -- if I understand your email correct the issue is not that you cannot resolve donate.wikimedia.org; but it's that one of our subdomains resolves to something that's not a WMF server? If so; the behavior you're seeing, that links.email.donate.wikimedia.org goes to ?.mkt41.net is correct. What we're doing is year is using an external bulk mailer to try and ensure deliverability of fundraising mail (it turns out that we get about $1 per email so getting good deliverability is pretty important.) The bulk mailer, Silverpop, does link rewriting in the body of the email for use statistical things (we A/B test our emails and use their dashboards to do so). For what its worth our donor rights policy [1] applies to this type of data.
