Actually that is an implementation issue. Depending upon how SA is
integrated into your mail system, it could get the envelope addresses.
(I know that mine does ;).
Making the envelope 'From' address available to SA works wonders when
trying to use 'whitelist_from_rcvd' to whitelist mailing lists such
as YahooGroups. ;)

However it is good to understand that this is an issue WRT whitelisting
and to know how your particular SA kit works.

Agree here.
