Hi all,
Hope someone can shed some light on my question. My company has 1 domino server, 1 domain(xxxxx.net), 225 users, we use a third party service for virus and spam protection (Messagelabs). Our mx record points to a cluster of MessageLab servers and then is scanned/checked and then we receive email to our server. Our domino server also is setup to relay all outbound back to Messagelabs for outbound scanning to ensure we are not sending virus/spam out.
Now for the issue. We are fixing to go through an email rebranding project with other companies owned by our corporate company. Our corporate company (domain is yyyyy.com) has decided to use another third party service which will allow for all of our companies (different domains) to appear as one domain without changing the existing email platforms or email addresses used by each individual company. So basically by using this third party service, the yyyyy.com domain will be used by all companies. The corporate domain (yyyyy.com) will point to the third party service/server, email alias will be setup for all of the subdomains and then mail will be routed to the individual companies and their domains. Example: f.lastname@yyyyy.com will somehow forward to firstname_lastname@xxxxx.net.(my domain).
I’m trying to get a better understanding of how exactly this will work. I’m guessing inbound will work, however currently our outbound relay is pointed back to our Messagelabs server cluster for scanning, so what points it back to the "other"third party server that changes our address.
The other service is called Blackspider and they offer Smart Host services.
Any help in understanding how this might work would be much appreciated.
