+ Postwhite is a policy server for Postfix MTA which filters incoming emails
+ based on per recipient whitelists managed by an email frontend.
+ Incoming emails are denied unless the sender address or sender domain is
+ present on the recipient's whitelist. This concept is neither new nor fancy
+ in itself, but the way Postwhite lets you manage your whitelist sure is.
+ Here is a real life example:
+ Arthur's main email address firstname.lastname@example.org is great for everyday
+ use, but he doesn't want to pollute it by using it for mailing lists,
+ websites, online shopping and such. Postwhite to the rescue! Arthur creates
+ a virtual email address email@example.com which is delivered to
+ the same mailbox. He adds this address to recipients.yml and then
+ restarts Postwhite.
+ Initially, all incoming emails will be denied, so when Arthur decides to
+ join the Betelgeuse mailing list, his whitelist has to learn about this.
+ Arthur sends an empty email to firstname.lastname@example.org which
+ puts Postwhite into learning mode for a limited period of time. In learning
+ mode, Postwhite allows and delivers any incoming mails, yet it
+ delivers a followup notification message along with it. When the first
+ email from the Betelgeuse mailing list comes in, Arthur simply replies to
+ the corresponding notification message thus adding Betelgeuse to the
