Habe da auch nicht die Überahnung; hier das , was ich in meiner Datenbank gefunden habe:
ETRN in configuration document is for INBOUND requests.
You must configure ETRN by (also) adding a connection document.
Actions:
1.
Configuration Document Settings:
Below is an example Configuration document (from the Router/SMTP Basics tab). Note, in particular, the settings in the following fields:
a. "SMTP used when sending messages outside of the local internet domain" is "Enabled"
b. "Relay host for messages leaving the local internet domain" is "relay.company.com"
2.
Local Area Connection Document Settings:
The Connection document shown below should have the following:
a. In the Basics tab, the Destination server field should have the outbound ISP server to which you are connecting.
b. In the Replication/Routing tab, the Routing Task field should be set to "Mail Routing," the Router Type set to "Pull Only," and the Pull Routing Request Protocol field set to "SMTP."
c. In the "Request the following when issuing a pull request field" section, you must only check the "The following server/domain/hosts" field, and enter the correct domain like: mydomain.com
