So far i haven't had any specific conflicts with firewalls unless if you're still insisting on outdated and old firewalls like Outpost 1.0, Sygate Firewall Free etc.Īlso, what difference does it make is Mail Shield acts as a mail client, using encrypted connection and then passing it unencrypted locally to the actual mail client compare to getting the mail encrypted directly to the mail client? And i doubt you'll gain as much security with firewall as you lose it by not using Web Shield. Click to expand.Nonsense and clearly don't understand the technology behind it.
