I use Windows Firewall Control and only when I disable it does it allow Ymail to sync.

I have other (non yahoo) emails but they are not blocked when Firewall is enabled.

I'm not getting any notification request to allow Yahoo so I how on earth am I gonna fix this? It just blocks sits there, forcing me to manually turn off filter just so that one mail account syncs. So my request is obvious, I do I permanently allow Yahoo to pass through?
