Can CGP send using TLS 1.2 when forwarding mail to a smarthost? (SMTP / Sending , Forward to...)

My client's ISP tells me TLS 1.2 is enabled on their server and they are going to retire 1.0 within a few months.
Send Encrypted (at the bottom of the same page) is configured properly.

However, in the logs, the TLS version used always seems to be 1.0:
12:32:03.191 2 TLS-000006 created(TLSv1.0,ECDHE_AES256_SHA) -> [x.x.x.x]:587 for SMTP-000007
12:32:03.277 4 SMTP-000007(*) TLS-000006 secure(ECDHE_AES256_SHA) connection opened

I don't know enough about TLS to be sure whether or not the issue is on CGP side or on the ISP side.
