Re: How can i check for open relay on smtp port?
Is there any reason you can't just directly connect to the SMTP server on port 25 and try relaying mail through that?
If you're asking how to test relaying from an address that you know is NOT allowed to relay, you might want to try a free proxy, and connecting to the SMTP server through that. Since the proxy should not be allowed to relay, you would know whether or not it is set up correctly.
