It depends on how your tcp_wrappers were compiled (with which options) and
from the contents of your hosts.allow and hosts.deny files. Lastly, it
depends what exactly you want to achieve with tcpd.
But some of these rejects can be avoided by _not_ using option PARANOID
for lines regarding SMTP, i.e. tcp-env, in the mentioned files.
