Whitelist works only for "Return-Path" field

[Joao Gazzoni]

Hello,

One message have these headers:
    From: Sucesu - RS <[EMAIL PROTECTED]>
    Reply-To: [EMAIL PROTECTED]
    Return-Path: [EMAIL PROTECTED]

And the SA whitelist have this record:
    From: [EMAIL PROTECTED] yes

But SA action is:
    Jun 24 00:03:05 MailScanner[14910]: Message j5O31n4N016061 from
    ([EMAIL PROTECTED]) to mydomain.com is spam, (escore=14.85)

Why SA uses "Return-Path" field instead "From" field, to perform
whitelist checks? There is some whitelist configuration mistake?

Thanks for any suggestion.
