DirectAdmin v1.646 has been released

I know about the RFC, but is this customisable?
Outgoing mail: SMTPS mail.example.com 465 SSL/TLS

Like Gmail has?
Port for SSL: 465
Port for TLS/STARTTLS: 587

Because more and more systems are not using 465 anymore, even the biggest Dutch ISP (Ziggo) is not advertising with it anymoer. And as you can see Gmail only uses SSL on this, not TLS which is a more mode SSL protocol.
Also hotmail is using starttls on port 587 and not advertising 465 anymore.

I think some might appreciate a customisable option for this if possible.
