If you are using LetsEncrypt to secure a mailserver with multiple domains you will have found that all domains must send their mail from the server's domain rather than their own in order to use TLS. This occurs because postscript can only use a single domain for TLS/SSL.

In this post I will describe a method to centralize the TLS certificate in a way that allows each domain to use its own domain name for smtp.
