How to use the Non-Local SMTP Delivery Bindings Per Domain feature on Messaging Gateway
Last Updated May 09, 2018
You want to know how the Non-Local SMTP Delivery Bindings Per Domain works.
The main goal of this feature is to allow administrators to create a separate identity for each of the company’s local domains.
Example: An administrator wants all mail sent from local domain X to be sent from IP address 1 and all mail sent from local domain Y to be sent from IP address 2. That way if users from domain X are abusive and has IP address 1 blacklisted by some outside domain, mail from domain Y are still accepted by the outside domain since all mail is sent by IP address 2.
Usually these are the necessary steps:
An administrator defines local domains
On each scanner host, the administrator associates an IP to be used for each local domain when sending non-local mail from each domain.
All non-local mail from a domain with configured IP bindings will send exclusively from the defined IP address.
NOTE: A domain can be associated with a single IP address or a range of IP addresses the MTA should bind to when sending non-local mail from the domain.
