tls_certificate — certificate to use for inbound and outbound mail
TLS_Certificate = "/path/to/cert"
Specifies the filename of a file containing a PEM encoded certificate that Momentum should present to remote mail exchanges (it is a client certificate). The file may contain both a certificate and a key.
The special value
none can be used to indicate that no certificate file should be used. This is useful to explicitly avoid using a certificate when a parent scope defines one.
tls_certificate is valid in the binding, binding_group, domain, ecstream_listener, esmtp_listener, global, http_listener, listen, pathway, pathway_group and peer scopes.
