Hello,

You are misparsing the logic, which essentially is

if REMOTE_SMTP_HELO_FROM_DNS is set then ignore any pre-defined setting of
REMOTE_SMTP_HELO_DATA and lookup the local host name in DNS instead.

Paul does not want to override/ignore his setting of
REMOTE_SMTP_HELO_DATA he wants exim to use it.
