[olug] qmail relay problem

[neal r]

   I've been getting messages periodically from various places
indicating that my SMTP server is an open relay - I've got it configured
to relay for a limited number of internal addresses. I went to abuse.net
and used their web query thing and I did get this result  -  it appears
that the machine is at least accepting this form of spam - anyone know
how to lock this down?



>>> RSET
<<< 250 flushed
>>> MAIL FROM:<spamtest@[63.170.238.6]>
<<< 250 ok
>>> RCPT TO:<relaytest%abuse.net@[63.170.238.6]>
<<< 250 ok
