Symptoms

I have subscriptions like example1.com, example2.com. How can I set multiple ip-adresses/ssl-certs on a postfix mail-node?

I want customers to be able to use mail server names like mail.example1.com and mail.example2.com.

Resolution

It is not possible to use multiple IP addresses on mail service node, and as a result multiple SSL certificates. Postfix Mail node works as shared Mail server and use one IP address.

Corresponding feature request was created: TP-141162. It will be implemented in future product updates.
