I agree that DNS reverse lookup for the local host name on
startup is not necessary in normal situations.
But it may be worth mentioning that qmail-smtpd copies
$TCPLOCALHOST into Received fields. If you run qmail-smtpd
under tcpserver -l0, you will see ``Received: ... by 0 ...''
in message headers.
People may or may not think this is a problem. If you
think this is a problem and still want to avoid looking up
in DNS, just specify the (real) local host name, not 0, as
the -l option's argument.
