Solution #00007251

Scope:
Email Security Gateway

Answer:
As of latest firmware we process the following fields for per-user white lists:
Envelope from
Header From
Header Reply-to:

The RFC states that the Reply-To is part of the "originator" information. It is however an optional field. See RFC2822 section 3.6.2 Originator Fields
It's likely some mailservers use a different From: and have the real from in the Reply-To field which is why we do this.
