Hi Rolf,
Well, that depends ...

I guess that depends on how impatient you are.
If you are using tcpserver (if you followed instructions at
http://lifewithqmail.org )then http://cr.yp.to/ucspi-tcp/tcpserver.html and
most of the people on this reccomend the following:
a.. -H: Do not look up the remote host name in DNS; remove the environment
variable $TCPREMOTEHOST. To avoid loops, you must use this option for
servers on TCP port 53.
a.. -l localname: Do not look up the local host name in DNS; use localname
for the environment variable $TCPLOCALHOST. A common choice for localname is
0. To avoid loops, you must use this option for servers on TCP port 53.
a.. -R: Do not attempt to obtain $TCPREMOTEINFO from the remote host. To
avoid loops, you must use this option for servers on TCP ports 53 and 113.
Hope that helps.
