SUCCESS
Relay Accepted - final response code 250
Check your email

As I can prevent this? I belive that my mail server are good configured....
The rules in optuse are bad?
I need a firewall to work better?
Any idea?
Thanks in advance.

I just tried as well. I didn't realize at first but what I did was "spamming" one of my email accounts *known* to the server. And yes, mail was sent in. It's supposed to receive mail and that's what it did!
Try the same link but then sending to your hotmail/yahoo account, or make something up. It'll say
551 Sorry members.iinet.net.au (203.59.24.150), I don't allow unauthorized relaying. You can't use me to send mail from to [address]
FAILURE
Unfortunately the program failed because...
The host machine does not relay

Opps!!!
It's really, I sending an a non local recipient and I get the error "551 Sorry members.iinet.net.au (203.59.24.150), I don't allow unauthorized relaying. You can't use me to send mail from to [address]

Thanks Urirama.
