Postfix: 2.10.1
One email address should receive email only from a known, finite list
of
senders.
All other senders' messages should be quarantined; but, this may not
be a
deal breaker.
Yes, we use amavisd and it does a good job with spam and virii. The
problem is with the unsolicited solicitations received by this
address.
Please, advise. Thank you.
One way to do this within Postfix itself (and so avoid the overhead of a
policy daemon or getting all the way to the delivery phase before
rejecting the message) is a restriction class. The
RESTRICTION_CLASS_README file in the Postfix documentation describes
almost exactly what you'd need in the 2nd example in the section titled
"Protecting internal email distribution lists" (a distribution list
being an obvious case where you may want to limit senders.)
