[atul]

Hello ALL,
I have already posted the spammer blocking query but Now I found that this from relay testing service that my server can was used for relaying messages!!

I took test and the last line posted as :
------------------------------------------------------
Hmmn, at first glance, host appeared to accept a message for relay.
---------------------------------------------------------

What can be done for this? How do I stop this?
THank you...

Which scanner did you use and what mail server are you running? I have a qmail server that comes up as "possible" open relay on one of those scanners.. However, it really didn't deliver the mail.. That may be the case for you too..
