I think your problems are addressed by Qmail's RELAYCLIENT
setting - setting this to null "" for local (your domain's) IP
addresses (using tcpserver to invoke qmail-smtpd). See
Dave Sill's Life with Qmail section 3.2.3, "Allowing Selective
Relaying".
If your users are not all on a fixed set of IP addresses, have
them check their mailbox before trying to send mail
(POP3 before SMTP), and apply the relevant patch from
the Qmail site (www.qmail.org).
cheers,
Andrew Richards.
