With the new 3.8 version, I start the Windows Live Mail application (Build 12.0.1606) and it creates a custom firewall rule. All is happy.
But if I change that policy to the predefined “Email Client” policy, it no longer connects. I used to run version 3.5 as “Email Client” and had no problems. If I remove the predefined policy and let it create its own custom policy again, all is well.
I have just read here that people recommend giving web browsers the predefined web browser policy, so I assumed that giving an email client the predefined policy for that would be a good idea as well.
Turns out with 3.8, that causes the client to not connect.
