Dell MD3000 - Issue with email Alerts

Hello,
I have 3 sites with Dell MD3000 Clusters and I am setting up email alerts, worked fine on the first site once I spotted the antivirus was blocking the email leaving the server so I allowed that
and its working fine but on the 2nd server I have a different issue.
When I press send the test I get the below error:
