I am setting up DKIM as per Cisco's instructions. I have generated a key, domain profile and put the ESA generated DNS txt into my DNS. If I test the DNS for DKIM from and external website the DKIM entry is seen. However, if I use the Test link in the ESA Domain Profile I get 'Warning DNS Lookup Failure. Cisco's instructions are very specific about giving DNS time to propagate but it has been 24 hrs. How does the test work? What are the likely reasons for the error (given that external web sites can see the DKIM entry)?

You are quite right, the ESA was probably using the internal DNS (priority 20) so I promoted an external DNS server to (15), and cleared the DNS cache. But, I am still getting the same error. I have checked and the external DNS is definitely active.
