Dear list, We need to implement TLS for one of our customers using our Postfix infrastructure (serving multiple domains) for inbound mail. The final delivery for that domain is a Exchange server, but we have a anti-virus server in front of that Exchange: internet -> postfix-relay -> AV-filter -> Exchange.
So we need to enable TLS at out postfix-relay. Lets say our server is called server.ourdomain.tld, and the customerdomain is customerdomain.tld. Do we need a cert for server.ourdomain.tld, or for customerdomain.tld? Can we add multiple domains using TLS in the future? Is this possible? Can you point me to some good how-to? Thx, P.
