I setup the Mail Server DNS as localhost because SMTP server is installed in my local machine. and also
mail server username
password
Receipt EMail sends from
New Order Notifications send to
Send Receipt EMails
has correct credentials. But still when i tried to "send test mail" (Send Test button), its throwing an following exception,
Mail Error occurred - Exception=Failure sending mail.
Unable to connect to the remote server
No connection could be made because the target machine actively refused it 127.0.0.1:25.
What could be the issue?
