Email not configuring with Thunderbird on el8.2

Thought I had a Thunderbird configuration issue on Centos 8.2, but it looks like Fail2Ban was banning my VPN’s IP while trying to initiate the configuration details of my new email. I turned off the VPN during the configuration and it worked fine. Now I guess I’ll have to see if Fail2Ban will muck up my send/receive further down the line in the future. I’ll watch the logs.
