I know, I'd just like it to raise a red flag or banner somewhere. In
corporate environments, i see reply-to hardly being used
Think it's a similar red flag like 'emails originating outside the
organization' (speaking of which can MailScanner flag that at the top of
an email rather than at the bottom?)
