I'm having an issue getting SMTP (outgoing) communication to work for a program on an application server.
I need help from an expert to identify what SMTP settings i would need to apply for my situation. I currently have it set as SMTP port 25 no TLS, no authentication required. Ive tried many combinations of those settings as well. All have failed.
I can access any of the servers we need to piece this together and also have access to Exchange in all regards.
The program in question is Manage Engine Service Desk and we have an on-premise Exchange 2013 CU 19 environment. The server the program resides on is Windows Server 2012 R2.
I'm curious about powershell commands that reveal the current SMTP settings and can maybe test connectivity from the application server to exchange itself, things like that. Im really stumped on why this doesn't work. I think it should be easy. Than again when we say Exchange i envision a large mountain. :)
Thank you for any help on this
