Don't set RELAYCLIENT for anyone but hosts you can explicitly trust.
hosts.allow (if you insist on using inetd/xinetd) should be configured
to _allow_ connections from anywhere, but only to set RELAYCLIENT for
hosts you should relay for. Most definitely you do _not_ want to allow
relay to hotmail. ;) To set this up under inetd/xinetd, consult the man
pages for their respective programs. You might be better off to avoid
inetd/xinetd altogether, and use tcpserver instead. Great instructions
for qmail & tcpserver can be found in Life With Qmail (aka LWQ) at:
