Just being cautious. A bad guy could set up reverse DNS entries to
make his IP addresses look like anyone he wants. By setting -p, you're
requiring that the name and IP address are listed both forwards and
backwards.

-R disables IDENT lookups, and -H disables host name lookups. Both are
potentially useful sources of information, and in most qmail
installations won't have severe performance penalty.
