IIS SMTP Open Relay
|
|
|
| Hi
I have a IIS server configured with SMTP in a public ip address. SMTP i have
configured with "openrelay" which is vulnerable for the security threats.
Please tell me how to close the SMTP open relay in this server without
specifying a IP address or address ranges.
Becouse there are some web developers need to have a access to this server
and test the application to send mails through this SMTP relay.
Pls advice.

| In addition to SMTP AUthentication mentioned by Bernard, you could have the
web developers host their applications on your web server. That way you only
need to allow relay to 127.0.0.1
