I have tried again and again to contact Kevin McCann at his posted email address. Here's what happens when I do:
Delivery to the following recipient failed permanently: email@example.com
Technical details of permanent failure:
Google tried to deliver your message, but it was rejected by the server for the recipient domain cruciverb.com by cruciverb.com. [22.214.171.124].
The error that the other server returned was:
