Issue Sending Mail Through SMTP. Is there a better fix than using the Domain Admin?

  • 772

Currently, we have SMTP Authentication setup via a Domain Admin account. I'm not a fan of the setup since it is a domain admin for an individuals admin account.

Is there a group that I could assign a dedicated account/service to resolve dependency on an individuals admin account?

Clarification. SMTP on the server is working, it's when SMTP is used via an application it fails. We found out recently that a domain admin account was being used for SMTP authentication because of a password expiration and the domain admin had to be set to not expire to prevent the issue. Having the domain admin configured to send email through this application creates a dependency and I'm looking to eliminate future headaches.

    It turns out that there was a Subnet/IP change and not one notified me. Here's the solution to the SMTP mail issue I had.

    1. Verified users IP/subnet with IPConfig /all
    2. Verified 220 SMTP mail connector response in the Application that the user was using via the testing feature of the application
    3. Verified the which Connector was being used by using Get-RecieveConnector to find the 220 banner correlated to the message (this may not be useful if the default 'banner' is being used)
    4. Used Exchange Control Panel (ECP) to add the Remote IP Address https://localhost/ecp/ > Mail Flow > Receive Connectors> Connector(by name)> Scoping and added the IP address for the users PC
    5. Verified by sending mail via the application SMTP mail test
