amavis whitelist rescipient address match

[Mark Martinec]

> What address does amavis use for whitelisting? To field or envelope?

Both since 2.6.0.  Before that only the envelope sender address was used.


amavisd-new-2.6.0 release notes:

- white and blacklisting now takes into account both the SMTP envelope
  sender address, as well as the author address from a header section
  (address(es) in a 'From:' header field). Note that whitelisting
  based only on a sender-specified address is mostly useless nowadays.
  For a reliable whitelisting see @author_to_policy_bank_maps below,
  as well as a set of whitelisting possibilities in SpamAssassin (based
  on DKIM, SPF, or on Received header fields);


> For Instance, given this email, what address would match a whitelist when
> luigirosa.com MTA receives this message?
> 
> 
> Return-Path: <root at acme.com>
> X-Original-To: lrosa at luigirosa.com
> Delivered-To: lrosa at luigirosa.com
> {various Received headers omitted}
> To: logwatch at acme.com
> Subject: Postfix log summary
> Message-Id: <20110529020209.06CFA1D08507 at acme.com>
> From: root at acme.com (root)

root at acme.com and root at acme.com
(actually just one in this case, as they are the same and duplicates
are eliminated).
