Avast Mail Shield and mail server

I’ve read post similar to mine but have yet to find a solution. The Avast Mail Shield works fine with my gmail and road runner accounts but it does not allow me to log into my Website email. The settings for my website email are the defaults for a pop3 account setting.

I just switched from Norton Security Suite to try out Avast. As mentioned, I can log into my gmail and road runner accounts but not my website email account. I could do this previously with Norton. If I disable the Avast Mail Shield, I can log into my website mail account.

Any help would be appreciated.

Thanks,
Brandon
