It uses the "real" relay address and name. Early on during processing,
mimedefang.pl sets $RelayHostname and $RelayAddr based on the
X-MIMEDefang-Relay... header.

That should never happen unless you use the ACCEPT_AND_NO_MORE_FILTERING
feature. The IP validation header is always deleted in the mimedefang C
code if it is found.
