No, actually; the most reliable way is to check the IP address of the
relay.  If outgoing mail *always* comes from the Exchange server, then
it's a piece of cake:

if ($RelayAddr eq "ip.of.exchange.box") {
   append_boilerplate(....)
}

Just a note:  The append_boilerplate function is deprecated because it
can misbehave on HTML mail.  You should really install the HTML::Parser
Perl module (and its dependencies) and use append_text_boilerplate and
append_html_boilerplate (see the mimedefang-filter man page.)

Regards,

David.
