Yes, it uses gethostbyaddr. I certainly don't trust any host name that
comes from the HELO command. However, the name that is written in the
log is the one HELO gives. Exim does not look up the FQDN unless it
needs it, in order not to waste effort.
However, to do what Neal wants is cheaper if you use Alan's suggested
config above, that uses only sender_net_accept_relay, since then Exim
does not have to call gethostbyaddr at all.
