Use Postfix to send mails with Windows Servers.

[guif]

hi!

I have a server with Postfix running and I think that it's running correctly because, If i put:

echo "" | mail -s "titulo" correo@gmail.com

...I recive inmediatly the mail

Now I would like to use this server to send mails from Windows servers.
I have the program smtpsend.exe to send mails. I use this command:

smtpsend.exe 11.0.1.3 -s"subject" -fusuario1@gmail.com -tusuario2@gmail.com

And the result is:

<<< 554 5.7.1 <-fusuario1@gmail.com>: Relay access denied smtpsend: expected 250

What's the problem?

thanks!
