Investigate options for allowing longer DNS lookup windows.
From user report:
"I looked at the result of the $response request in postmark.../wp-mail.php and got this error:
wp-error - http request error - name lookup timed out.
It appears my dns was a bit slow. So I looked up the docs of the wp_remote_post function and added a timeout option to the $args array and that fixed it."
