Why just that, and not ask for defaulting primary_hostname and/or smtp_active_hostname to the rDNS on an incoming connection? > interface = x.x.x.x > helo_data = interface_rdns Is it often that you won't know what x.x.x.x resolves to? Anyway, try this interface = x.x.x.x helo_data = ${lookup dnsdb{ptr=x.x.x.x}{$value}{[x.x.x.x]}} And hope the PTR has an RFC 2821-compliant value if it exists. FWIW, in my configuration on a box with several interfaces I have things set up for opposite effect: interface = ${lookup dnsdb{a=$primary_hostname}} That would perhaps be a more sensible default to change, if anything were to be changed here. But I wouldn't change anything if it were up to me (which it's not). I've heard multi-homed systems like this are the reason for RFC 2821's prohibition on rejecting if the HELO arg doesn't resolve to the connecting address. -- Configure bugmail: http://www.exim.org/bugzilla/userprefs.cgi?tab=email -- ## List details at http://www.exim.org/mailman/listinfo/exim-dev Exim details at http://www.exim.org/ ##
