Need help for following issue.
Mail from internal application still not being relayed to recipients of distribution group
But if I changed the delivery management setting from "Only senders inside my organization" to "Senders inside and outside of my organization" and I was then able to telnet to exchange from the application server in question and send the email to the distribution group in question and I see it went out to all of the recipients in the DG.
Although it is working in this way, it's not ideal, as now anyone from the outside can also send email to that DG.
So what is the better solution to this problem? Adding the Exchange server permission to the SMTP Relay receive connector.
Thank sin advance.
