Postwhite is only a tool that helps accelerate the implementation of policies. As with many things that present themselves to Postfix admins, you need to decide what those policies are. So it's up to you to determine whether any given host's published mailers should be included in your whitelist. As of postwhite v1.3.2 (most current), web.com is not included in the default list of hosts. If you choose to add it, it's very easy to do. If any of the default hosts in postwhite are worrisome to you, it's just as easy to remove them. SteveJ
