Links in email defaulting to post.website.com - why?

I'll be researching this in a little while and will post back.

The original link in the email and its rewritten equivalent are both what you should expect.

The link https://originalpage.example.com should be rewritten to http://trackingdomain.example.net/<uniqueid>. When somebody hits the tracking domain, their hit is logged, and then they're immediately redirected to the original page. Again, this is standard behavior w/Marketo.

And there's nothing fatally wrong with the DNS domain(s) at this point in time in my tests.  (There is a minor misconfiguration on Marketo's side that's outside of your control.)

However, if you saw that DNS error earlier today on the tracking domain post.bofifederalbank.com, that strongly suggests that either your nameservers or one of Marketo's nameservers were having transient problems earlier. If this recurs, please post back here right away
