DKIM is not authenticating in Google Apps

What steps have you taken to resolve the issue?

We have tried removing the DKIM record in Cloudflare. Tested both 1024 and 2048 length and neither of them are working.

This is what I’m seeing;

v=DKIM1; k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCAZMXj8WpMkdhGQolUV3wES1lA+4nY9BuHUa3oV8DP5MnphQJbHq2zNxWH3CM6aXC7GtQuXr/LC8ncJZFDqB1YnYjqf8zoF9JWCOR1evhzcb7fTsx+DlbF0UjQp2A0z2qZ/SSgDkYSaOWvUz0cAxTZVIhjxDKRM/MawTvcq6CxUwIDAQAB

I’m guessing that MXToolbox didn’t know which selector to check.

What’s the key supposed to be?
