Hi team,

I'm configuring local SMTP virtual server to use the email service of tomcat webapp(pwm) which is installed in Active Directory(EC2 Windows) Server.

But when I checked the Server Manager, it says

"Message delivery to the host '*IP Address which I don't know*' failed while delivering to the remote domain '*mydomainname.com*' for the following reason: The remote server did not respond to a connection attempt.

# in the windows server
I configured the port of smtp server as 587 and I allowed 587 ports in both outbound and inbound firewalls. Also, I allowed localhost(127.0.0.1) in relay restrictions and access connection too. I chose the basic authentication with TLS encryption for the outbound security. Also, since I use local email smtp server, the security group and nacl rules are not related with this issue but I checked them also and the ports are all allowed.

# in the pwm administrator configuration
I put the basic authentication information and 127.0.0.1, 587 as a default email server of the service.

I googled this error and tried my best. Could you help me out? What do I have to check more?
