Forwarding Blacklist

Adding domains to this list means that users are not able to forward any emails to users of the domains. This is to prevent issues with companies that have strict spam policies and blacklist the sending server for forwarded spam.

This feature is commonly used for AOL, which blacklists servers that forward spam to their servers. If this becomes a problem, you may decide to add AOL.com to your forwarding blacklist.
