SMTP TLS configuration

Hi,

Trying to enable TLS on a UTM9 9.510-5

The steps i have done so far is:

1. created a certificate Signing request

2.got it signed from a public CA

3. Exported the certificate with chain as in .p12 format

4. installed the certificate via Certificate Management > New Certificate > Upload

5. under Email Protection > SMTP > Advanced > TLS Settings > selected the certificate, TLS version = TLS v1 or higher

Require TLS Negotiation Host/Nets = empty

Require TLS Negotiation Sender Domains = empty

Skip TLS Negotiation Hosts/Nets = Any

When testing SMTP TLS i Got no STARTTLS option

Should the configuration offer TLS?

any suggesting?

Kind Regards

Jesper Hanno
