I did it a different way, I disabled the authentication on the local server for specific account. This account sends the e-mail to itself and its work.
I have Dell Storage SC 7020 and I want turn on SMTP Server. When I test server everything is fine, but mail dont work. I have issue "503 This mail server requires authentication when attempting to send to a non-local e-mail address", but I dont have any authentication option. Are there any other options out there? What can I do? [IMAGE]
