Hello, when you connect to my email server from the internet I am able to get the internal FQDN after mail submission. I tested it and am able to see two types of 2.6.0 DSN's
- 250 2.6.0 <46885057-751b-4029-9cvd-98c837c05acc@W2K8R2-ESP2-1.domain.com> [InternalId=3180] Queued mail for delivery
- 250 2.6.0 [InternalId=3185] Queued mail for delivery
I want to make it so that the first DSN is different for the Internet Receive Connector, I don't want any internal information leaking out to anyone. Can this be achieved?
