------- Comment #2 from holmgren@lysator.liu.se 2007-01-26 00:38 -------
Resolution of bug 248 means that helo_data can be set to "${lookup dnsdb
{ptr=$sending_ip_address}}" or "${lookup dnsdb
{ptr=$sending_ip_address}{$value}{$primary_hostname}}" but should that be the
default (the default currently is "$primary_hostname") or should the default be
NULL/"", and if expansion yields nothing then the outgoing interface is
reverse-looked up without involving expand_string()? It's a bit more efficient
but requires more code.

I firmly believe the default should stay as it is. (1) Changing it would be
incompatible and I expect would trip people up. (2) I am sure the vast majority
of hosts have just one IP address (or at least just one identity) and so do not
need to fiddle with this. (3) There are also hosts, I'm sure, where the reverse
lookup will not work.
